Childhood trauma can severely affect the development of the brain, resulting in the alteration of neural circuits which are involved in emotional regulation and threat detection. Childhood trauma has been associated with a wide array of mental health disorders such as bipolar disorder, anxiety, post traumatic stress disorder (PTSD), and depression.
Having a close family member affected by a mental illness is the largest known risk factor, to date. [6] However, linkage analysis and genome-wide association studies have found few reproducible risk factors. [1] Heterogeneity is an important factor to consider when dealing with genetics. Two types of heterogeneity have been identified in ...
Any damage to the brain can cause a mental disorder. The brain is the control system for the nervous system and the rest of the body. Without it, the body cannot function properly. [71] Increased mood swings, insane behavior, and substance abuse disorders are traumatic brain injury (TBI) examples. Findings on the relationship between TBI ...
When it comes to brain health, some things are out of your control. Age is the biggest risk factor for developing dementia, according to the World Health Organization, but others such as genetics ...
Huntington's disease (HD) is a rare autosomal dominant neurodegenerative disorder caused by mutations in the huntingtin gene (HTT). HD is characterized by loss of medium spiny neurons and astrogliosis. [30] [31] [32] The first brain region to be substantially affected is the striatum, followed by degeneration of the frontal and temporal ...
The brain plays a big part in the aging process, and scientists think they’ve pinpointed the specific cells that control it.. In a study of mice, researchers at the Allen Institute identified ...
Around 65% of people have some kind of health problem as a result of congenital genetic mutations. [7] Due to the significantly large number of genetic disorders, approximately 1 in 21 people are affected by a genetic disorder classified as "rare" (usually defined as affecting less than 1 in 2,000 people). Most genetic disorders are rare in ...
“Social activities, like visiting with friends or participating in clubs, or having hobbies that engage your mind, also seem to have benefits in preserving brain health and preventing cognitive ...
