Genetic Identification of Major Psychiatric Disorders

Most major psychiatric diagnoses are defined as descriptive syndromes based on expert consensus. Mental Disorders Diagnostic Statistics Manual (DSM) and International Disease Classification (ICD) are standard diagnostic tools used by psychiatrists and clinicians all over the world. Unfortunately, these manuals have been categorized by clinical protocols and revised every few years. Permanent revision and medical renovation of psychiatric disorders are also used to diagnose and treat psychiatric disorders such as autism spectrum disorder (ASD), schizophrenia, attention deficit hyperactivity disorder (ADHD), major depression, dilemmas It brought.

Researchers at the ADHD cross-lesion group and the other four genetically related mental disorders / diseases-psychiatric genome association researchers found that ADHD, schizophrenia, major depression, bipolar disorder, and autistic spectrum disorders According to Variation American Psychiatric Association (APA), 5% of American children suffer ADHD. However, as a result of the community survey, it is necessary to be aware that higher ratios are estimated in the US survey. These surveys asked their parents whether they received a diagnosis of ADHD from medical professionals.

In February 2013, a study found a common genetic association between five major mental illnesses, autism, ADHD, bipolar disorder, major depression, and schizophrenia. Abnormal function of the neurotransmitter system is related to various psychiatric disorders including serotonin, norepinephrine, dopamine, and glutamate system. In some cases, there are differences in the size and activity of specific brain regions. Psychological mechanisms such as cognitive (eg inference) bias, emotional influence, personality dynamics, temperament, and coping style are also involved. It has proved more difficult to reliably identify the association between a particular gene and a specific type of disease, but that the genetic variation can play an important role in the development of mental disorders Has been shown by research. It involves environmental accidents including pregnancy and childbirth
