Neurosis is a group of psychiatric disorders that have a certain personality basis and often have psychosocial influences in their onset. The main manifestations are anxiety, depression, fear, obsessions, hypochondriasis, somatization symptoms, or neurosis symptoms. Anxiety is an inner experience of fear, depression or panic from mild tension and slight discomfort. A neurological disorder in which anxiety is the main clinical phase is called anxiety disorder. There are two main clinical forms of anxiety disorders: panic disorder and generalized anxiety. Generalized anxiety is generally anxiety and fear without a clear objective object or specific content. In addition to anxious mood, there are significant vegetative symptoms such as dizziness, palpitations, chest tightness, dry mouth, frequent urination, sweating, tremors and other autonomic symptoms and muscle tension, as well as motor restlessness. Panic disorder is a neurological disorder in which panic attacks are the primary and main clinical phase. And panic attacks as secondary symptoms are seen in many different psychiatric disorders. Obsessive-compulsive disorder has obsessive-compulsive symptoms as the main clinical phase. It is characterized by the coexistence of conscious self-compulsion and counter-compulsion. The patient experiences that the ideas or impulses originate from the ego but are against his or her will; he or she resists but is unable to control them; he or she is aware of the abnormality of the compulsions but is unable to get rid of them. The patient is aware of the abnormality of the compulsive symptoms but cannot get rid of them. Somatoform disorder is a neurological disorder characterized by a persistent fear or belief in the predominance of various somatic symptoms. Patients repeatedly seek medical attention for these symptoms, and various negative medical tests and physicians’ explanations fail to dispel their doubts. Even if some kind of somatic disorder is sometimes present, it does not explain the nature or extent of the symptoms complained of, or their distress and predominant perceptions. Patients often deny the presence of psychological factors. There is a refusal to explore the possibility of a psychological etiology. Patients often have a degree of self-centeredness and believe that their disorder is somatic in nature and become indignant if the patient cannot convince the physician to accept this. Somatization disorders present with a wide variety of frequently changing somatic symptoms that can involve any system or organ of the body, most commonly gastrointestinal discomfort (e.g., pain, hiccups, acid reflux, vomiting, nausea, etc.), abnormal skin sensations (e.g., itching, burning, tingling, numbness, soreness, etc.), skin spots, sexual and menstrual complaints are also common, and significant depression and anxiety are often present. Patients have undergone numerous tests for this purpose, with no positive findings. Hypochondriasis is dominated by a persistent dominant notion of fear or belief in a serious physical illness, for which the patient has repeatedly sought medical attention, and various negative medical tests and explanations by the physician have failed to dispel his or her doubts. These symptoms are often of a chronic and fluctuating course and are accompanied by severe and long-standing social, interpersonal and family behavioral disturbances that rarely resolve completely.
