One particularly bad episode of my mother beating the hell out of me…

This is not easy and I don’t really want to do this or subject you to it, but apparently you have to face these things, come to terms with them, grieve over them and release them Many of the books, almost all of the books I’ve read say this. So here goes…

One particularly bad episode of my mother beating the hell out of me was when I was four years old. She came to pick me up from preschool. We got home. I was chewing gum that a friend of mine had given me. I was not allowed to chew gum because my mother thought I would get cavities. But my friend had offered it to me, and being the forbidden fruit, I had taken it and popped it in my mouth.

My mother saw me chewing. She asked what I had in my mouth. I became very scared and said it was candy and spit it out on the ground before we went inside the house. She asked me again inside and I didn’t say anything. She went outside, found the piece of gum I’d spit out, came in and started punching me in my face. She had rings on. She hit me as hard as she could, when her hand got tired, she took off her shoes and hit me with those.

I had black eyes, a bloody nose, fat lips, bleeding copiously. The house was dark and I sat there, blood dripping from my face , black and blue marks getting bigger on my body. How does a four year old handle this onslaught from the one person who was supposed to love her? I don’t remember, I have no emotional memories of this event even though it is recorded in my brain vividly and accurately. The first emotion I remember was after the incidence. When my mother saw what she had done to me and felt guilty and came over and started to clean the blood off my face. I felt pure hatred. I felt anger. I knew what she had done was wrong. I knew I did not deserve it, and I hated her for it.

These kinds of things happened regularly, whenever she felt like it, she would completely lose control and beat me into a pulp. She used shoes, sticks, large cutting board sized wooden boards, hitting me against walls and furniture and leave me bleeding and bruised. With my hatred of her growing every time.

Finally, she dragged me by my hair, up to a second floor room. I was 14 years by then, bigger than her. She was whaling on me, hitting me, kicking me, when I got so angry, I lifted my hand to strike her. I didn’t hit her, but I wanted to. She immediately stopped. Went downstairs and told my aunts that I tried to hit her. They all came to me and said “How could you lift your hand on your mom, you must apologize!” I just looked at them and thought, FUCK that, I won’t apologize! And I didn’t.

I hated my mother, almost all the time. Of course I did love her, too. Very confusing, she wasn’t horrible to me all the time, but whenever she wanted to, she pummeled me. She had no control, no one to whom she was accountable. All my relatives except my adored grandmother looked the other way, but my grandmother was bedridden by then and couldn’t do much about it except shout at my mother to stop. My mother shouted back and told my grandmother that I was her daughter and she could do whatever she wanted with me. Not quite true, but that’s what she, in her crazed mind, thought.

From four years of age to 14, I was horrendously abused, blood, gore, she probably broke my nose, I do have a broken nose. Black and blue marks. Hidden with clothes so I could go to school, or I simply stayed at home if I looked too much like hell.

Did I deserve this, NO! Can anyone wonder why my flight or fight response is overactive?
Did I get love, affection, encouragement? Yes, from my grandmother. Did it make a difference, of course it did. Did it wipe out all the effects of the abuse inflicted upon me by my mother? No. Did it negate the fact that my father abandoned me at age 5? No.

Sometimes I wonder how, after suffering all this, without addressing it, how have I survived? Strength. That’s how. I was strong enough to know that my mother was wrong when I was 4 years old. I must have cried, I don’t remember it, but I was strong enough to get up the next morning, and the next morning and the next and go on with my life, never knowing when the insane woman would beat me to a pulp again.

I was strong enough to forgive her in the late 1990’s, realizing that this old woman was not the same person who abused me, this old woman was my mother who was as sorry as she could be that she abused me. We did have a good relationship for a few years before she passed away in 2005.

Now I am doing all the inner child work that adult survivors of child abuse have to do to get their lives back. I am 55 years old and what happened to me when I was 3, 4 years old still affects me. So I am reparenting myself, letting myself experience and mourn what happened to me and I am hoping that will make me “whole” again. That’s what the books, therapists, psychologists, that’s what everyone says. Be there for the frightened child, the “inner child,” be loving and comforting to her and things will get better.

I think what this means is to make my fight or flight response less triggerable. When I am feeling intense emotions, possibly out of place, then if I can calm myself down and not have a cow, that’s progress. Imagine the child I was, how could I NOT have an overactive fight or flight? Of course I did. Any little thing could have been an inducement for my insane mother to beat the living daylights out of me. So now, I have to reprogram my brain to not feel things at the catastrophic levels I used to as a child. I’m thinking that’s what we’re doing with all this inner child stuff. Self calming, self soothing.

I am reading books, upon books. Gleaning whatever is appropriate for me and hoping that I will heal. I feel I am healing. I am healing. Every time my fight or flight gets insane, I calm myself down. I also remind myself that I am not alone, in that many others have gone through this and worse, and I have many friends and family members who love me, and whom I love dearly. I’ve put two pictures in this post, one the absolute most happiest day of my life, the day my son was born, with my mother holding him. She was not the same person in this pictures as the one who abused me, and I forgive her with all my heart and tell her that I love her and I hope her spirit is in peace. The second picture is of the day we took my son home. Another very happy day of our lives. And so we move on and heal and grow and live our lives with strength and love.

Sometimes life is not fair. But lemonade’s still good!

Aral my newborn baby!

A very happy day as well! Two days after my son was born. Taking him home!

Depression is more than a mental disorder: It affects the whole organism

http://www.neuroscientistnews.com/clinical-updates/depression-more-mental-disorder-it-affects-whole-organism
An international team of researchers lead by the University of Granada (UGR) has scientifically proven, for the first time, that depression is more than a mental disorder: it causes important alterations of the oxidative stress, so it should be considered a systemic disease, since it affects the whole organism.

The results of this work, published in the Journal of Clinical Psychiatry, could explain the significant association that depression has with cardiovascular diseases and cancer, and why people suffering from depression die younger. At the same time, this research may help finding new therapeutic targets for the prevention and treatment of depression.
The lead author of this work is Sara Jiménez Fernández, PhD student at the UGR and psychiatrist at the Child and Adolescent Mental Health Unit at Jaén Medical Center (Jaén, Spain). The co-authors are the UGR Psychiatry professors Manuel Gurpegui Fernández de Legaria and Francisco Díaz Atienza, in collaboration, among others, with Christoph Correll from the Zucker Hillside Hospital (New York, USA).
This research is a meta analysis of 29 previous studies which comprise 3961 people, and it is the first detailed work of its kind about what happens in the organism of people suffering from depression. It studies the imbalance between the individual increase of various oxidative stress parameters (especially malondialdehyde, a biomarker to measure the oxidative deterioration of the cell membrane) and the decrease in antioxidant substances (such as uric acid, zinc, and the superoxide dismutase enzyme).
The researchers have managed to prove that, after receiving the usual treatment against depression, the patients’ malondialdehyde levels are significantly reduced, to the point that they are indistinguishable from healthy individuals. At the same time, zinc and uric acid levels increase until reaching normal levels (something that does not occur in the case of the superoxide dismutase enzyme).

Antipsychotic Treatment for Bipolar Disorder Not Always Effective After Six Months

Ok first of all, sorry, but I have to say this, is Dr. Yatham the Indian cousin of (ugh) Donald Trump? Wow excellent combover, Lakshmi!

Alright, got that out of my system, lets get on to business, in this study they say that patients with bipolar 1 who stayed on mood stabilizers (lithium or Valproate) and antipsychotics (risperidone or olanzapine) for over a year did no better than patients who only stayed on the medications for 24 weeks. These are typical antipsychotics. They have severe side effects like bad weight gain and tardive dyskenisia, normally these antipsychotics are prescribed for schizoaffective disorder and schizophrenia as well.

“beyond six months of use, those taking risperidone experienced manic or depressive episodes as frequently as the placebo group. Those taking olanzapine, on the other hand, had the fewest episodes when using the medication over a whole year rather than stopping use after 24 weeks, making the year-long treatment most effective for that drug. Risperidone tended to delay mania, while olanzapine tended to delay depression.”

My personal experience: taking 900 mg/day of Lithium Carbonate ER, and 100 mg of Quetiapine Fumarate has kept me stable for over a year now. That is, mood-wise. Of course the childhood abandonment and abuse issues are no picnic, none at all, they are unpleasant, painful, not any fun! But if I hadn’t been stable mood-wise, I would not have been able to tackle these. And time it is, to tackle these.

So gratitude and love and laughter for all.

Lakshmi N. Yatham, M.D. - Brain & Behavior Research Expert on Bipolar Disorder

Lakshmi N. Yatham, M.D.

Some antipsychotic medicines commonly used to treat a type of bipolar disorder may not have clear benefits after six months of use, researchers have found.

Some antipsychotic medicines commonly used to treat a type of bipolar disorder may not have clear benefits after six months of use, researchers have found.

There are different types of bipolar disorder. Bipolar I — what most people associate with the illness — is characterized by periods of mania (intense elevated mood, increased energy and speed of thinking, reduced sleep etc) and severedepression (low mood, no interest or motivation, lack of pleasure, suicidal thoughts etc) . This new study is the first to compare the effectiveness of certain antipsychotics in treating this type of bipolar disorder longer-term, following a period of mania.

Publishing their findings online October 13 in Molecular Psychiatry, the research team was led by Lakshmi N. Yatham, M.D., of the University of British Columbia, a 1996 NARSAD Young Investigator (YI) grantee who went on to receive Independent Investigator (II) grants in 1999 and 2003.

The study focused on people with Bipolar I being treated with a combination of an antipsychotic (risperidone or olanzapine) and a mood stabilizer (lithium or valproate). The patients enrolled in the study had recently experienced manic episodes. To compare how the antipsychotics worked over long periods, some patients continued on whichever antipsychotic they were already taking, for another six months or one year in conjunction with lithium or valproate. Others, serving as controls, took placebos (or dummy pills) instead of antipsychotics along with lithium or valproate. Then, the three groups were compared: How long did it take before each patient experienced another depressive or manic episode?

Overall, the researchers found, patients were less likely to have a mood episode if they continued on antipsychotics for 24 weeks rather than taking placebos . However, the benefits of continuing antipsychotics beyond 24 weeks were not apparent as the proportion of patients that had a mood episode was not different between 24 and 52 groups.

The team noted that extended use of both antipsychotics was accompanied by weight gain in patients — clinically significant weight gain on olanzapine in 35% of patients after a year of use, and some weight gain in 15%-17% of patients on risperidone with any length of use. This suggests that the relief provided by these drugs should be considered against the potential for significant weight gain.

The researchers also observed some differences between the two types of antipsychotics as regards their longer-term usefulness, and the types of mood episodes each antipsychotic medicine helped to prevent , although they caution that these findings must be considered preliminary . For instance, beyond six months of use, those taking risperidone experienced manic or depressive episodes as frequently as the placebo group. Those taking olanzapine, on the other hand, had the fewest episodes when using the medication over a whole year rather than stopping use after 24 weeks, making the year-long treatment most effective for that drug. Risperidone tended to delay mania, while olanzapine tended to delay depression. To unpack the effects of different treatments, the researchers say, future work should examine other types of antipsychotics as well as non-antipsychotic treatments like psychotherapy, and do so in a larger patient group.

Is Depression Just Bad Chemistry?

Hmmm, seems it’s more than that. It’s not just lower levels of Serotonin, like those cute little rock people show us in the commercial for Zoloft. Some antidepressants that decrease Serotonin levels actually help with the symptoms of depression. Seems a lot of areas in the brain, eg. the amygdala, the hypothalamus, the anterior cingulate cortex, all may be of different sizes and activities than in people who do not suffer from depression. Also deep brain stimulation of the subcallosal cingulate gyrus alleviates depression symptoms. Well, it seems the whole thing is much more complicated than little rock people becoming happy and hopping around with little bluebirds… the red bolds are mine.

http://www.scientificamerican.com/article/is-depression-just-bad-chemistry/

A commercial sponsored by Pfizer, the drug company that manufactures the antidepressant Zoloft, asserts, “While the cause [of depression] is unknown, depression may be related to an imbalance of natural chemicals between nerve cells in the brain. Prescription Zoloft works to correct this imbalance.” Using advertisements such as this one, pharmaceutical companies have widely promoted the idea that depression results from a chemical imbalance in the brain.

The general idea is that a deficiency of certain neurotransmitters (chemical messengers) at synapses, or tiny gaps, between neurons interferes with the transmission of nerve impulses, causing or contributing to depression. One of these neurotransmitters, serotonin, has attracted the most attention, but many others, including norepinephrine and dopamine, have also been granted supporting roles in the story.

Much of the general public seems to have accepted the chemical imbalance hypothesis uncritically. For example, in a 2007 survey of 262 undergraduates, psychologist Christopher M. France of Cleveland State University and his colleagues found that 84.7 percent of participants found it “likely” that chemical imbalances cause depression. In reality, however, depression cannot be boiled down to an excess or deficit of any particular chemical or even a suite of chemicals. “Chemical imbalance is sort of last-century thinking. It’s much more complicated than that,” neuroscientist Joseph Coyle of Harvard Medical School was quoted as saying in a blog by National Public Radio’s Alix Spiegel.

Indeed, it is very likely that depression stems from influences other than neurotransmitter abnormalities. Among the problems correlated with the disease are irregularities in brain structure and function, disturbances in neural circuitry, and various psychological contributions, such as life stressors. Of course, all these influences ultimately operate at the level of physiology, but understanding them requires explanations from other vantage points.

Are Your Chemicals out of Balance?
Perhaps the most frequently cited evidence in support of the chemical imbalance hypothesis is the effectiveness of antidepressants, many of which increase the amounts of serotonin and other neurotransmitters at synapses. Zoloft, Prozac and similar selective serotonin reuptake inhibitors (SSRIs) result in such an increase and can often relieve depression, at least when it is severe. As a result, many believe that a deficiency in serotonin and other neurotransmitters causes the disorder. But just because a drug reduces symptoms of a disease does not mean that those symptoms were caused by a chemical problem the drug corrects. Aspirin alleviates headaches, but headaches are not caused by a deficiency of aspirin.

Evidence against the hypothesis comes from the efficacy of a newly developed antidepressant, Stablon (Tianeptine), which decreases levels of serotonin at synapses. Indeed, in different experiments, activation or blockage of certain serotonin receptors has improved or worsened depression symptoms in an unpredictable manner. A further challenge to the chemical imbalance hypothesis is that many depressed people are not helped by SSRIs. In a 2009 review article psychiatrist Michael Gitlin of the University of California, Los Angeles, reported that one third of those treated with antidepressants do not improve, and a significant proportion of the remainder get somewhat better but remain depressed. If antidepressants correct a chemical imbalance that underlies depression, all or most depressed people should get better after taking them. That they do not suggests that we have only barely begun to understand the disorder at a molecular level. As a result, we must consider other, nonchemical leads.

This Is Your Brain on Depression
A possible clue lies in brain structures. Imaging studies have revealed that certain brain areas differ in size between depressed and mentally healthy individuals. For example, the amygdala, which responds to the emotional significance of events, tends to be smaller in depressed people than in those without the disorder. Other emotional regulatory centers that appear to be reduced in volume are the hippocampus, an interior brain region involved in emotional memory, the anterior cingulate cortex, which helps to govern impulse control and empathy, and certain sections of the prefrontal cortex, which plays an important role in emotional regulation. Nevertheless, the effects of these shrinkages on depression, if any, remain an open question.

Neuroimaging studies have revealed that the amygdala, hypothalamus and anterior cingulate cortex are often less active in depressed people. Some parts of the prefrontal cortex also show diminished activity, whereas other regions display the opposite pattern. The subcallosal cingulate gyrus, a region near the anterior cingulate, often shows abnormal activity levels in depressed individuals. These differences may contribute to depression, but if they do, scientists are not sure how.

In 2012 neurosurgeon Andres M. Lozano of the University of Toronto and his associates studied the effects of deep brain stimulation of the subcallosal cingulate gyrus in depressed patients who had not benefited from standard treatments. The intervention led to a significant reduction in symptoms of depression, supporting the idea that a dysfunction in this brain area may be involved in the illness.

Findings also point to a crucial role for psychosocial factors such as stress, especially when it arises from a loss of someone close to you or a failure to meet a major life goal. When someone is under a good deal of stress, a hormone called cortisol is released into the bloodstream by the adrenal glands. Over the short term, cortisol helps humans cope with dangers by mobilizing energy stores for flight or fight. But chronically high cortisol levels can harm some bodily systems. For example, at least in animals, excess cortisol reduces the volume of the hippocampus, which in turn may contribute to depression. Despite such data, we still do not know if stress alters the human brain in ways that can lead to depression.

Seeing the Elephant
Throughout this column, we have described associations between various brain changes and depression. We have not talked about “causes,” because no studies have established a cause-and-effect relation between any brain or psychosocial dysfunction and the disorder. In addition, depression almost certainly does not result from just one change in the brain or environmental factor. A focus on one piece of the depression puzzle—be it brain chemistry, neural networks or stress—is shortsighted.

The tunnel-vision approach is reminiscent of a classic story in which a group of blind men touch an elephant to learn what the animal looks like. Each one feels a different part, such as the trunk or the tusk. The men then compare notes and learn that they are in complete disagreement about the animal’s appearance. To understand the causes of depression, we have to see the entire elephant—that is, we must integrate what we know at multiple scales, from molecules to the mind to the world we live in.

Exercise, Reading, Healing

I went to the gym today to begin using my personal training sessions. My trainer, Jaime, measured me and I am so thrilled, I found out my waist is 25 inches! Also, I did 25 sit ups, 20 pushups, and the “wall sit” for over 2 minutes! I could have kept sitting too 🙂 Pretty good stats for the beginning. I feel really happy, and excited to be embarking on a physical fitness journey again. I’ve let exercising slide a bit, but it is time. The beach is only a few months away haha.

Sorry for the “Dear Diary” tone of this post, but that’s all I have today, and actually, considering I feel a real sense of wellbeing, it is enough for me 🙂

The reason I’ve been ignoring the physical side of me is because I’ve been intensively working on the emotional, abandonment, abuse issues and healing from them. I have read one book (a long one), and I still have many more on my list. And happily, what I have learned from the book I’ve read and from perusing many others, as well the wise people who wrote them, is that healing is possible! It is very possible! And unbelievably so, but I have been feeling the beginnings of healing inside me. I recognize my “inner child”, or Little, and I recognize when she is feeling scared and I know to give her love and reassurance. That is healing! Not to get beside myself, and feel bereft, and look to something or someone outside of my self for help or love or anything. But to give this love and reassurance to my self, that is healing! And I am doing this all the time now. And, so, as a result, I am feeling emotionally stronger, more resilient and much less needy. Hallelujah!

Below are the books I have ordered. I have read “From Abandonment to Healing” by Susan Anderson.  And  I’ll be starting “Changing Course” by Claudia Black next.

“Anchored to the fate of my life” by Pieces of Bipolar

Such truth and pain in these words, and such strength. Unless you’ve been through this, you’ll never know. But then I’ll never know what you’ve walked through either. Life demands strength, we cannot be weak and wallow and expect to thrive. After everything, after the fall, after the storm, after it all, the one standing is the strong one.

How Walking in Nature Changes the Brain (hint: it’s good!)

http://mobile.nytimes.com/blogs/well/2015/07/22/how-nature-changes-the-brain/?utm_source=FB&utm_medium=social&utm_campaign=FB_paid&referer=http://m.facebook.com

JULY 22, 2015
A walk in the park may soothe the mind and, in the process, change the workings of our brains in ways that improve our mental health, according to an interesting new study of the physical effects on the brain of visiting nature.

Most of us today live in cities and spend far less time outside in green, natural spaces than people did several generations ago.
City dwellers also have a higher risk for anxiety, depression and other mental illnesses than people living outside urban centers, studies show.
These developments seem to be linked to some extent, according to a growing body of research. Various studies have found that urban dwellers with little access to green spaces have a higher incidence of psychological problems than people living near parks and that city dwellers who visit natural environments have lower levels of stress hormones immediately afterward than people who have not recently been outside.
But just how a visit to a park or other green space might alter mood has been unclear. Does experiencing nature actually change our brains in some way that affects our emotional health?
That possibility intrigued Gregory Bratman, a graduate student at the Emmett Interdisciplinary Program in Environment and Resources at Stanford University, who has been studying the psychological effects of urban living. In an earlier study published last month, he and his colleagues found that volunteers who walked briefly through a lush, green portion of the Stanford campus were more attentive and happier afterward than volunteers who strolled for the same amount of time near heavy traffic.
But that study did not examine the neurological mechanisms that might underlie the effects of being outside in nature.
So for the new study, which was published last week in Proceedings of the National Academy of Sciences, Mr. Bratman and his collaborators decided to closely scrutinize what effect a walk might have on a person’s tendency to brood.
Brooding, which is known among cognitive scientists as morbid rumination, is a mental state familiar to most of us, in which we can’t seem to stop chewing over the ways in which things are wrong with ourselves and our lives. This broken-record fretting is not healthy or helpful. It can be a precursor to depression and is disproportionately common among city dwellers compared with people living outside urban areas, studies show.
Perhaps most interesting for the purposes of Mr. Bratman and his colleagues, however, such rumination also is strongly associated with increased activity in a portion of the brain known as the subgenual prefrontal cortex.
If the researchers could track activity in that part of the brain before and after people visited nature, Mr. Bratman realized, they would have a better idea about whether and to what extent nature changes people’s minds.
Mr. Bratman and his colleagues first gathered 38 healthy, adult city dwellers and asked them to complete a questionnaire to determine their normal level of morbid rumination.
The researchers also checked for brain activity in each volunteer’s subgenual prefrontal cortex, using scans that track blood flow through the brain. Greater blood flow to parts of the brain usually signals more activity in those areas.
Then the scientists randomly assigned half of the volunteers to walk for 90 minutes through a leafy, quiet, parklike portion of the Stanford campus or next to a loud, hectic, multi-lane highway in Palo Alto. The volunteers were not allowed to have companions or listen to music. They were allowed to walk at their own pace.
Immediately after completing their walks, the volunteers returned to the lab and repeated both the questionnaire and the brain scan.
As might have been expected, walking along the highway had not soothed people’s minds. Blood flow to their subgenual prefrontal cortex was still high and their broodiness scores were unchanged.
But the volunteers who had strolled along the quiet, tree-lined paths showed slight but meaningful improvements in their mental health, according to their scores on the questionnaire. They were not dwelling on the negative aspects of their lives as much as they had been before the walk.
They also had less blood flow to the subgenual prefrontal cortex. That portion of their brains were quieter.
These results “strongly suggest that getting out into natural environments” could be an easy and almost immediate way to improve moods for city dwellers, Mr. Bratman said.
But of course many questions remain, he said, including how much time in nature is sufficient or ideal for our mental health, as well as what aspects of the natural world are most soothing. Is it the greenery, quiet, sunniness, loamy smells, all of those, or something else that lifts our moods? Do we need to be walking or otherwise physically active outside to gain the fullest psychological benefits? Should we be alone or could companionship amplify mood enhancements?
“There’s a tremendous amount of study that still needs to be done,” Mr. Bratman said.
But in the meantime, he pointed out, there is little downside to strolling through the nearest park, and some chance that you might beneficially muffle, at least for awhile, your subgenual prefrontal cortex.

Cool News: Raising Body Temperature Can Relieve Depression

 Apparently, depressed patients have higher body temperatures. So increasing their temp even more so that the body’s cooling mechanism kicks in and cools the body and brain is a good thing. It alleviates depression for up to 6 weeks. Ok.

http://bipolarnews.org/?p=3660&utm_source=twitterfeed&utm_medium=twitterRaising body temperature by a few degrees may produce antidepressant effects as the body’s cooling mechanisms kick in. At the US Psychiatric and Mental Health Congress in 2015, researcher Charles Raison described a study comparing the effects of exposing participants to a special heating coil in a tent that retained the heat until their body temperatures increased by a few degrees to those of a sham procedure that did not raise body temperature. Those participants whose body temperature was increased had a lower body temperature the following day, and their depression improved as their bodies cooled. These improvements lasted six weeks or more.
Depressed patients tend to have elevated body temperatures. Raison suggests that raising body temperatures even more prompts the body’s cooling mechanisms to compensate, bringing cooling activity to normal levels from the skin to the brain and improving depression.

Blocking inflammation prevents cell death, improves memory in Alzheimer’s disease

 Once again, the immune system, specifically inflammation, plays a huge role in Alzheimer’s, a neurodegenerative disease. Mental illness, in some ways, is very close to a neurodegenerative disease. I wonder, I always wonder, what if it’s the immune system and inflammation that is responsible for diseases such as bipolar d/o or schizophrenia. 

http://www.neuroscientistnews.com/research-news/blocking-inflammation-prevents-cell-death-improves-memory-alzheimers-disease

Using a drug compound created to treat cancer, University of California, Irvine (UCI) neurobiologists have disarmed the brain’s response to the distinctive beta-amyloid plaques that are the hallmark of Alzheimer’s disease.
Kim Green and colleagues with UCI’s Institute for Memory Impairments and Neurological Disorders found that flushing away the abundant inflammatory cells produced in reaction to beta-amyloid plaques restored memory function in test mice. Their study showed that these microglia cells contribute to the neuronal and memory deficits seen in this neurodegenerative disease. Results appear in the journal Brain.

“Our findings demonstrate the critical role that inflammation plays in Alzheimer’s-related memory and cognitive losses,” said Green, an assistant professor of neurobiology & behavior. “While we were successful in removing the elevated microglia resulting from beta-amyloid, further research is required to better understand the link among beta-amyloid, inflammation and neurodegeneration in Alzheimer’s.”  

The neurobiologists treated Alzheimer’s disease model mice with a small-molecule inhibitor compound called pexidartinib, or PLX3397, which is currently being used in several phase 2 oncology studies and a phase 3 clinical trial to treat a benign neoplasm of the joints.
The inhibitor works by selectively blocking signaling of microglial surface receptors, known as colony-stimulating factor 1 receptors, which are necessary for microglial survival and proliferation in response to various stimuli, including beta-amyloid. This led to a dramatic reduction of these inflammatory cells, allowing for analysis of their role in Alzheimer’s. The researchers noted a lack of neuron death and improved memory and cognition in the pexidartinib-treated mice, along with renewed growth of dendritic spines that enable brain neurons to communicate.
Green said that although the compound swept away microglia, the beta-amyloid remained, raising new questions about the part these plaques play in Alzheimer’s neurodegenerative process.
In healthy tissue, microglia act as the first and main form of immune defense in the central nervous system. But in a disease state, such as Alzheimer’s, microglia appear to turn against the healthy tissue they were originally assigned to protect, causing inflammation in the brain. The beta-amyloid plaques in brain areas related to Alzheimer’s disease are rich with these rogue microglia, Green added.
“Our work is telling us that these cells may contribute to the disease process, and targeting them with such specific drugs is a promising new approach,” he said.
