Asthenic brain syndrome

Introduction Cerebral weakness syndrome is an early symptom of brain organic mental disorder. Neurosis is a type of neurosis. Although many clinical symptoms are similar, they are essentially different. Definitions refer to a series of clinical symptoms in which brain function gradually declines due to atrophy of brain cells. Common reasons are: long-term troubles, anxiety; life is too leisure after retirement, living environment is too quiet, and little contact with the surrounding people.

Cause

Although there are certain psychosocial factors in the brain weakness syndrome, it can be found that the symptoms are organic lesions. Cerebral weakness syndrome is an early symptom of brain organic mental disorder. Neurosis is a type of neurosis. Although many clinical symptoms are similar, they are essentially different. The speed is slow, the work efficiency is declining, the initiative is declining, and it is difficult to learn new knowledge without active learning, the memory is declining, and the memory decline is more obvious.

Main clinical manifestations:

(1) Affective Disorder: It is a typical symptom, which is characterized by emotional instability, emotional fragility, restrained emotional expression ability is obviously weakened, can not control emotional reaction, can not be irritated and invisible, under the stimulation of tiny trauma It shows obvious susceptibility, irritability, irritability, grievances, etc. The patient is willing to control his emotions, sometimes feels unnecessary and embarrassed, but often can't restrain himself. Therefore, some patients are troubled by this. Patients with severe illness may have emotional incontinence, that is, mandatory crying.

(2) various physical discomfort symptoms: These symptoms are often used as the main complaint symptoms, such as headache, dizziness, numbness of the limbs, walking to one side, muscle tremor, sleep disorders and so on.

(3) Inadequate attention, slow thinking, decreased work efficiency, decreased initiative, feeling that learning new knowledge is difficult without active learning, memory decline, and memory decline is more obvious.

The patient has self-knowledge and above-mentioned symptoms, and a small number of patients may be associated with anxiety symptoms and suspected symptoms. When the symptoms are mild, they are often not taken seriously. They can also be considered as symptoms of hypertension or other medical diseases. For the elderly with the above symptoms, the nervous system and laboratory tests should be performed. If evidence of cerebral arteriosclerosis is clearly found, If the head CT has a small infarct, etc., the diagnosis can be confirmed. If there is no evidence, the diagnosis cannot be denied.

Differential diagnosis

Brain weakness syndrome needs to be differentiated from neurasthenia:

The main symptoms of neurasthenia are decreased ability in all aspects and increased response to various stimuli. Psychological levels are prone to fatigue, sleep disorders, inattention, memory loss, and anxiety with horror. It is susceptibility to sound, light or various parts of the body, such as weak heart and various sexual dysfunction. The definition of neurasthenia determined at the Symposium on Neurosis in China in 1985 pointed out that patients with this disease are prone to excitement and mental fatigue, often accompanied by emotional annoyance and some psychophysiological symptoms. Some scholars believe that the fatigue of neurasthenia is selective, that is, it is not easy to be tired of the emotional experience of interest, but it is easy to be tired of those who are not interested or subconscious.

The clinical phase of cerebral weakness syndrome and neurasthenia is severely characterized by brain dysfunction; the clinical features of cerebral weakness syndrome are obvious, persistent emotional incontinence or instability, so it is also called organic emotional instability. Obstacles, the specific differences are as follows:

(1) Both headache and dizziness symptoms are similar, but vertigo is common in cerebral weakness syndrome, which is vestibular dysfunction (ischemia); neurasthenia is rare.

(2) Limb numbness, tingling symptoms, brain weakness syndrome is common, is the symptoms of peripheral nerves; neurasthenia is rare, but visible muscle pain.

(3) Affective Disorders Different neurasthenia patients may be troubled during a small part of the course of the disease, unable to relax, irritating, etc., or mild anxiety or depressive symptoms; patients with cerebral weakness syndrome Significant, persistent emotional instability, emotional vulnerability, irritability, anxiety or depression.

(4) Debilitating symptoms, neurasthenia patients with conscious mental retardation, inattention or inability to maintain, conscious physical fatigue, work and learning efficiency, memory loss, etc.; patients with cerebral weakness syndrome have similar symptoms, the difference between the two : When performing memory tests, neurasthenia is in the normal range, and patients with cerebral weakness syndrome can often find memory loss. When dealing with daily life and social activities, neurasthenia often emphasizes that their memory declines, but there is no obvious forgetting phenomenon, and patients with cerebral weakness syndrome often need to prepare a memo to remind themselves, otherwise it will affect social activities because of forgetting. .

(5) In the thinking and language expression, patients with brain weakness syndrome may have obvious thinking stagnation, speech sputum, no primary and secondary, no center (pathological description), slow thinking and other phenomena, and neurasthenia No similar symptoms.

(6) Excitatory symptoms Patients with neurasthenia may have mental excitement, increased recall and association, consciously restrained and distressed symptoms, but patients with cerebral weakness syndrome have no similar symptoms.

(7) The diseases accompanying the body and the laboratory tests for neurasthenia generally have no organic diseases in the body, laboratory tests are mostly normal; patients with cerebral weakness syndrome are often accompanied by physical diseases such as hypertension, coronary heart disease and diabetes. Abdominal examinations often have abnormal findings, such as head CT, MRI, blood lipids, EEG, memory tests, etc. can be seen abnormal, can be used as evidence of brain organic disorders.
