Patient's question:
Older patient, intermittent psychosis, 7 cases of mental illness in family members of the same generation, will it be inherited to the daughter? Now the daughter has given birth to another daughter, will these conditions have a genetic inheritance?Doctor's answer:
Hello, mental illness refers to severe psychological disorders where patients' cognitive, emotional, volitional, and motor behaviors may exhibit persistent and significant abnormalities.Guidance: It can be said that mental illness has a genetic component, which is a concern for many relatives of patients with mental illness and the general public. Current medical research has proven that most mental illnesses are related to genetic factors. Some mental illnesses have been confirmed as genetic disorders with clear modes of inheritance, such as familial amaurotic dementia, phenylketonuria, Huntington's disease, Down syndrome, Wilson's disease, and schizophrenia. Other mental illnesses may involve genetic factors in their onset, but the extent of their role and the precise mode of inheritance are not yet certain, such as conversion disorder.
Although genetics plays a significant role in the etiology of mental illness, it is not an absolute factor. That is, children with a genetic predisposition do not necessarily develop the illness, and we cannot overlook the influence of postnatal living environments.
