Constant rumination is clinically involved in a wide range of disorders, which can be schizophrenia, depression, anxiety, phobias, and also obsessive-compulsive disorder. But the content of ruminations is different. Patients with schizophrenia tend to have ruminations related to hallucinations, delusions, and schizophrenics have poor coordination with their surroundings and often have no self-awareness. In contrast, patients with depression tend to have recurrent thoughts about the past, presenting with depressed mood, slow thinking responses, feelings of uselessness, incompetence, and despair, and often have self-denial, feeling incompetent, worthless, and unloved about themselves. In contrast, patients with anxiety disorders rumination are often inexplicably worried, accompanied by symptoms of plant nerve dysfunction. Phobic patients are fearful and worried about specific things and tend to have ruminations about specific situations, accompanied by plant nerve dysfunction and avoidance behaviors. In OCD, the repeated thoughts are often compulsive, and some patients have compulsive behaviors, such as compulsive checking and washing. The constant rumination may be compulsive thinking, such as compulsive exhaustion, and so on. Therefore, it is necessary to analyze the specific problem and further examination of the relevant content is needed.
