Before explaining in greater detail the main risk factors for psychosis, it should be mentioned that psychosis does not normally develop from a single cause, since in reality it is usually caused by the appearance and interaction of various factors (genetic or biological factors, environments, lifestyle, etc.)

Among these risk factors are a number of medical problems capable of causing psychosis, such as the following: abuse of alcohol or some drugs, as well as during withdrawal from this type of substance, some brain diseases, some tumors, dementia, HIV, some drugs, cerebrovascular accidents or strokes or some types of epilepsy, among others. Below we will explain in more detail what the main risk factors for psychosis consist of.

Some studies in this regard have shown as a result that the accumulation of circumstances or traumatic events during early ages makes a person more vulnerable to the possibility of developing a mental disorder, including psychotic disorders.

5. Some obstetric and perinatal complications

These types of complications would be some of the main risk factors for psychosis since the perinatal period, according to experts, is a period of maximum vulnerability. Among the factors associated during this period with the possible subsequent development of a psychosis are the following: birth premature, low birth weight, viral infections in the second trimester of pregnancy, complications in childbirth, malnutrition in pregnancy, etc.
