Some culture-bound syndromes appear with similar features in several cultures, but with locally specific traits, such as penis panics. A culture-specific syndrome is not the same as a geographically localized disease with specific, identifiable, causal tissue abnormalities, such as kuru or sleeping sickness , or genetic conditions limited to ...
Twin studies have found CU traits to be highly heritable, and not significantly related to environmental factors such as socioeconomic status, school quality, or parent quality. [6] Two twin studies suggested a significant genetic influence for CU, with an estimated average amount of variation (42.5%) in CU traits accounted for by genetic ...
Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
Antisocial personality disorder (ASPD) is a personality disorder defined by a chronic pattern of behavior that disregards the rights and well-being of others. People with ASPD often exhibit behavior that conflicts with social norms, leading to issues with interpersonal relationships, employment, and legal matters.
[4] [5] Psychosocial stressors, such as unemployment and reduced job performance, may also be risk factors. [2] [20] There could also be a genetic element. A study of monozygotic and dizygotic twins found that genetic components contributed 7% to 21% of somatic symptoms, with the remainder related to environmental factors. [21]
An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics.
Similarly, several studies have shown that traits of psychiatric illnesses (such as traits of PTSD and other anxiety disorders) can be transmitted epigenetically [18] [19] Parental exposure to various stimuli, both positive and negative, can cause transgenerational epigenetic and behavioral effects.
For any trait of interest, observed differences among individuals "may be due to differences in the genes" coding for a trait and "the result of variation in environmental condition". This variability is due to gene-environment interactions that influence genetic expression patterns and trait heritability. [72]
