Genetic Factors
Genetic factors are the strongest risk factor for psychosis. It is estimated that up to 80% of the risk of developing psychosis is due to genetic factors. Studies have shown that having a first-degree relative with psychosis increases the risk of developing psychosis by up to 10-fold. Additionally, the risk is further increased if the relative has a more severe form of psychosis.
Environmental Factors
Environmental factors can also increase the risk of developing psychosis. The most common environmental risk factors include: exposure to childhood trauma, exposure to substances such as cannabis, poverty, social isolation, and urban living. Additionally, certain medical conditions, such as autoimmune diseases, can also increase the risk of developing psychosis.
Psychological Factors
Psychological factors, such as stress, can also increase the risk of developing psychosis. Stress can cause an individual to have difficulty managing their emotions, which can lead to a psychotic episode. Additionally, certain personality traits, such as being more introverted or having less emotional stability, can also increase the risk of developing psychosis.
