A stroke that damages parts of your amygdala would have what effects?

A stroke that damages parts of your amygdala would have what effects?

Fear itself: The amygdala is located in both temporal lobes. One of the chief functions is coordination of perception with fearfulness. Damage to the amygdala can have either stimulatory (fear-enhancing) or inhibitory (fear-negating) effects; either of which can be quite impairing. Other aspects of mood and behavior can be affected. Epilepsy is not infrequently a byproduct of amygdalar damage. ...Read more

What does the amygdala have to do to with the adrenal?

What does the amygdala have to do to with the adrenal?

Stress feedback loop: The amygdala is part of the limbic system of your brain. The limbic system responds to and regulates emotion; the amygdala assigns emotional "valence" to stimuli. It registers whether stimuli are threatening, leading to fight-flight responses. The adrenal can secrete stress hormones in response to all this, such as epinephrine, norepinephrine, and cortisol. ...Read more

What is the chemical make up of lariam.  What is the specific chemical in this drug that would react with the amygdala?

Mefloquine: Lariam® is mefloquine, an antimalarial drug. It can cause neuropsychiatric side effects like confusion, irrational fear, hallucinations, unusual thoughts or behavior, and others. I'm not a neuroscientist and don't know if any of these are related to the amygdala. Other antimalarial drugs usually can be substituted it. If you have such symptoms, immediately see a doctor experienced in malaria. ...Read more

Does anterior cingulate cortex turn off amygdala completely or simply make us unable to see emotions?

Does anterior cingulate cortex turn off amygdala completely or simply make us unable to see emotions?

Network analysis: Neural networks exist in the brain subserving certain functions, often specific to that network. Anterior cingulate (acc) and amygdala are in one such circuit. Disrupting communications between the two will cause changes in each component. Re-establishment of communications by re-wiring the brain (plasticity) may cause restoration of function but it may be abnormal-hence altered emotionality. ...Read more

Is the amygdala smaller in a person with OCD? I'd like to understand my brain a little better.

Is the amygdala smaller in a person with OCD? I'd like to understand my brain a little better.

Size is not at issue: Proper functioning is more the issue than size. Some efforts have been explored at retraining this 'anxiety switch'. Read this and discuss it w/ your therapist. http://www.articledashboard.com/Article/How-You-Can-Retrain-The-Amygdala-Gland-To-Cure-Obsessive-Compulsive-Disorder/242240 There may be other ideas they'll have. Best! ...Read more

Can somebody with OCD exhaust their amygdala either with thinking too much/stress or taking d-cycloserine?

Can somebody with OCD exhaust their amygdala either with thinking too much/stress or taking d-cycloserine?

No reason to worry: Please don't let this idea take any of your time or energy. The mygdala is not in any way over-worked by over-thinking. You are, but it isn't. Also, the studies on the medication's effects are w/ rats and those that show anything do not show exhaustion, merely reduction of pain reaction. Talk w/ your therapist to confirm, but trust this - there is not need for you to worry about this. Best wishes. ...Read more

Docs figured out my SympatheticNervousSystem was wayyy overactive(had extreme insomnia, fear, agitation, palps).Long-term damage to amygdala or other?

Docs figured out my SympatheticNervousSystem was wayyy overactive(had extreme insomnia, fear, agitation, palps).Long-term damage to amygdala or other?

Beta blockers: I assume that an endocrinologist has ruled out hyperthyroidism and other glandular overactivity that could cause many of your symptoms. Beta blockers,avoidance of caffeine and alcohol along with stress management therapy and judicious use of tranquillizers are possible treatments for your symptoms.I am more concerned about long term effects on the cardiovascular system than on the amygdala. ...Read more

How does dopamine and serotonin (chemically) reduce fear/anxiety in de brain? prefrontal cortex or amygdala? Or which parts of brain is involved?

How does dopamine and serotonin (chemically) reduce fear/anxiety in de brain? prefrontal cortex or amygdala? Or which parts of brain is involved?

Neurotransmitters: Medicines like Zoloft/Lexapro are serotonin reuptake inhibitors. Wellbutrin inhibits the uptake of norepinephrine and dopamine. Whether it is anxiety, irritability, anger, short fuse, or depression; these medicines regulate neurotransmitters in the brain to improve symptoms of insomnia, guilty feelings, poor concentration, fatigue, appetite disturbance, and lack of drive/interests. ...Read more
