Free and total testosterone correlated positively with anger and DHT correlated positively with verbal aggression and anger, whereas cortisol correlated negatively with physical aggression and anger in the AGG- group.
Conclusions: There is a link between T, DHT and externalizing behavior in male adolescents at risk for psychopathology. Due to the findings of highest androgen levels in boys with persistent externalizing behavior, a role of androgens in the development of disruptive or later antisocial disorders can be hypothesized.
Too much DHT may contribute to male pattern baldness, depression and hair growth in women, and prostate enlargement.
Testosterone activates the subcortical areas of the brain to produce aggression, while cortisol and serotonin act antagonistically with testosterone to reduce its effects.
DHT induces circuit modifications by changing the number of excitatory spine synapses in a paracrine manner, which in turn affects the cognitive function of the brain (12). Cognitive function is the result of high-level neural activity in the human brain. It mainly involves verbal, spatial and memory ability (13).
Foods rich in lycopene such as tomatoes, watermelons, carrots, and mangoes naturally block DHT production. Biotin-rich foods like berries, liver, legumes, oily fish, and bananas condition the skin and scalp creating an overall healthy environment for strong hair.
There is evidence that testosterone levels are higher in individuals with aggressive behavior, such as prisoners who have committed violent crimes. Several field studies have also shown that testosterone levels increase during the aggressive phases of sports games.
The hormonal changes of menopause, combined with its side effects, can have a significant impact on your mood. It's not out of the ordinary to experience mood swings, sadness, and even rage during this time. In fact, one study found that for 70 percent of women, irritability is the most common symptom.
Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression.
Increased DHT activity at your hair follicles is partly responsible for this hair loss, in addition to other factors, including genetic ones. High levels of DHT can shrink your hair follicles and shorten the hair growth cycle, resulting in hair loss.
DHT blockers are safe and effective for most men. However, some DHT-blocking medications may cause side effects, including sexual side effects. The most common side effects of finasteride include decreased libido, erectile dysfunction (ED) and ejaculation issues, such as a reduction in semen volume.
The use of blockers has shown lots of side effects in men. The biggest being it stops hair growth all over the body, adversely impacts the libido, leads to sexual dysfunction and also results in loss of muscle tissue.
Increased DHT (dihydrotestosterone) can be caused by conditions such as benign prostatic hyperplasia (BPH), prostate cancer, male pattern hair loss (androgenic alopecia), and excessive male-pattern hair growth in females (hirsutism).
These data indicate that T's 5alpha-reduced metabolite, DHT, can reduce anxiety behavior and that blocking metabolism to 3alpha-diol in the hippocampus can attenuate these effects.
Your attention narrows and becomes locked onto the target of your anger. Soon you can pay attention to nothing else. In quick succession, additional brain neurotransmitters and hormones (among them adrenaline and noradrenaline) are released which trigger a lasting state of arousal. You're now ready to fight.
When used this way, without proper medical supervision, testosterone has been linked to unwanted side effects such as mood swings and aggressive “roid rage.”
Testosterone did not make men respond more quickly than those on placebo, so the authors of the new study concluded that testosterone didn't increase “emotional reactivity.” Instead, testosterone “has a more restricted effect that is consistent with increasing status-enhancing aggressive and nonaggressive behaviors.”
Researchers found that increases in the thyroid hormone thyroxine, not testosterone, were linked to anger. Increases in testosterone were actually associated with forgetfulness and poor concentration (4). Interestingly, many men also turn irritable when their testosterone levels fall below normal.
Zinc for Hair Loss
It may seem strange, because even though DHT levels are raised, production is limited. Using zinc as a DHT blocker is not effective. Zinc helps to keep hormone levels regulated, which is one of the reasons why it is so effective in preventing and treating hair loss.
Is DHT hair loss reversible? Yes, a DHT hair loss treatment can help you get your lost hair line. Though, it can only happen if you act promptly.
Niacin aka Vitamin B3
Not only does niacin promote healthy blood flow in the scalp, which is good for your follicles and blocks the effects of DHT, but it also works well with other nutrients such as biotin, making both of them more effective for healthier hair.
