Schizophrenia spectrum disorders are characterized by disturbances in thinking, emotions, and behavior, including subtypes such as paranoid, adolescent, and nervous. Typical symptoms include hallucinations, speech disorders, and emotional apathy, which can only be diagnosed if the symptoms persist for more than 6 months. This disease requires long-term medication maintenance treatment, combined with psychological and social rehabilitation training.

3. Mood disorders

Mood disorders mainly manifest as abnormal emotional regulation and are divided into two categories: depressive disorders and bipolar disorder. Depression is characterized by persistent low mood, while bipolar disorder alternates between depressive and manic episodes. This type of disease has a high genetic predisposition and requires attention to identifying suicide risk signals.

4. Neurodevelopmental disorders

Neurodevelopmental disorders occur in childhood, including autism spectrum disorder, attention deficit hyperactivity disorder, etc. Symptoms involve social interaction deficits, lack of concentration, or hyperactive impulses. Early behavioral intervention has a good effect, and some cases can last until adulthood.

5. Stress related disorders

Stress related disorders are triggered by major life events, including acute stress disorder, post-traumatic stress disorder, etc. Typical manifestations include traumatic re experience, increased alertness, and avoidance behavior. Psychological therapy is the main intervention method, and in severe cases, anti anxiety drugs can be used for a short period of time.
