Neurosis, also known as neurosis, is not an organic lesion but a general term for mental disorders, including neurasthenia, obsessive-compulsive disorder, and anxiety disorders. They can usually be seen in a psychiatric department, neurology or psychiatry. The cause of neurosis is usually closely related to various adverse psychosocial factors, including anxiety, tension, emotional agitation and so on. Adverse emotions may affect the excitatory or inhibitory effects of the central nervous system, and there may also be dysfunctions in the regulation of the vegetative nervous system, which may cause sympathetic excitation. Symptoms of neurosis attacks are varied, generally manifested as headache, insomnia, memory loss, and some patients may also experience palpitations, chest tightness, and a sense of terror. Involvement of the vegetative nerve function may also appear in the head and a variety of visceral discomfort, including neurasthenia, fatigue, constipation, diarrhea, near-death feeling and other symptoms. Therefore, if the above symptoms occur, it is recommended to consult a psychiatrist, neurologist or psychiatrist in a timely manner, and if necessary, other departments such as gastroenterology and respiratory medicine for treatment of related symptoms, after excluding other physical diseases. Neurosis is prone to recurrent episodes, and you should pay attention to maintaining an optimistic attitude in your daily life, eliminating bad emotions in time, and reducing the triggering factors of the disease.
