Researchers have discovered a pattern of genetic glitches and behavioral features, such as delayed walking, in some cases of autism spectrum disorder (asd) that could ultimately lead to identification of subgroups and improved treatment. Major psychiatric disorders, such as schizophrenia and bipolar disorder, have been shown in numerous studies to have significant genetic factors involved in their etiology the effects of environment and gene-environment interactions on the expression of the disorders are thought to be important, but need more study. Since its inception, the national institute of mental health (nimh) has recognized the importance of genetics in understanding mental disorders from the earliest epidemiological studies to today’s molecular approaches, the institute has invested broadly in genetics research in hopes of discovering the interplay between genes and the.

Nonetheless, they concluded, one implication of the study is that genetics can contribute to prediction and prevention of psychiatric diseases, along with the identification of molecular targets. Mental disorders to better prevent, detect, and treat mental illness and to alleviate such consequences mental illness is associated with many contributing and/or causative factors. Researchers have discovered that five major mental disorders may be linked to the same common inherited genetic variations, according to a study published in the journal nature genetics. Most genetic diseases are the direct result of a mutation in one gene however, one of the most difficult problems ahead is to further elucidate how genes contribute to diseases that have a complex pattern of inheritance, such as in the cases of diabetes , asthma , cancer , and mental illness.
