Male vs Female BRAINS (Part 7)



SITE: “Your Default Brain Is Female”




F: Women think in webs, constantly connecting ideas. Since part of their corpus callosum is 25% larger than Ms, they can easily bounce back and forth between feelings and facts. They will often define a problem in broader terms, examining a wide range of potential factors before considering solutions.
Women want to process & explore. Because they tend to personalize, they’re more inclined to talk through the issue to reach understanding

M : Men’s brains gravitate toward facts & logic. They’re more likely to think in straight lines, processing facts one step at a time. They want to define & clarify a problem, so they start by isolating & eliminating issues. They’re great in a crisis, constantly scanning for potential threats & then solutions

Ms tend to depersonalize & externalize issues or problems. They need time to think through solutions, often in solitude. This gives their brain an opportunity to explore, unwind & decide what to do next.

One study found that when Ms – under stress – looked at angry faces, they emotionally disengaged. Brain scans showed lower activity in areas responsible for processing other people’s emotions (temporal pole) & facial expressions (Amygdala – re. fear / Insula – re. empathy), by measuring cortisol levels.
Stressed Fs showed more activity in those brain regions.

Both Ms & Fs release the hormone oxytocin during stressful events.
M: tend to have a “fight or flight” response to stress. Adult men’s brains (& adolescents of both genders) – show a much weaker neural response than Fs. Under stress they produce high levels of testosterone, which reduces the effects of oxytocin, making them angrier & more violent

F: Adult women tested had a strong neural response to unambiguous visual threat-signals, & generally better at evaluation it. In stressful situations they cope with a “tend & befriend” strategy – taking care of themselves, children, & forming strong group-bonds

However, their cortisol levels are 2x higher than men’s at work, but 4x higher at home. If they can’t process or collaborate with others, they don’t produce enough oxytocin, making it hard to recover from stress

Gender is a critical determinant of mental health & mental illness.….such as  depression, anxiety & somatic complaints…… Differences have been reported in age-of-onset symptoms, frequency of psychotic symptoms, course of disorders, social adjustment & long term outcome” (MORE….)

: Male brains synthesize serotonin much faster than Fs. Common male-biased conditions include autism, ADHD,
conduct disorder, dyslexia & other language impairment, retardation, Tourette’s & schizophrenia.
Re. Alzheimer’s shows in up to 90% of older men, & show significantly larger heart ventricles than healthy men

Also : Men are 3x more likely to be diagnosed with Antisocial Personality Disorder (APD).
Their lifetime prevalence rate for alcohol dependence is more than 2x higher than Fs.  In developed countries, it’s MEN – about 1 in 5, & WOMEN – 1 in 12.

: Fs are far more likely to suffer from dementia, mood disorders, PTSD after a traumatizing event, & anorexia nervosa. But if they have dyslexia, they’re more able to compensate for it than men
Unipolar depression, predicted to be the 2nd leading cause of global disability by 2020, is 2x more likely than in men

Re. Alzheimer’s, it’s found in only 8-10 % of age-matched women
Re. Schizophrenia – no heart ventricle enlargement is seen in women with the disease

Longevity gap: more than 1/2 of all U.S. women over 65 are widows, by 3-1 = for every 100 women, there are only 77 men. By age 85 they outnumber men 2.6 to 1. Re: health : “WHY do MEN LAG BEHIND? 13 FACTORs & remedies

IMP: As of 2019, the average U.S. life expectancy has been declining for 3 consecutive years. A baby born in 2017 is expected to live to age 78.6, down from 78.7 the year before (F / M averaged)
CAUSES:  Rise in drug over doses, liver disease / cirrhosis, & suicide.
Also, in the U.K. lifespan is projected to be shortened by about 5 mths.
