Brain organic disorder

Introduction Brain organic mental disorders refer to mental disorders caused by brain infections, degeneration, vascular diseases, trauma, tumors, etc., also known as brain organic psychosis. With the extension of human life, the aging population is gradually increasing, and the incidence of brain organic mental disorders is also significantly increased.

Cause

Closed and open craniocerebral injury caused by various reasons is the main factor of the disease, and the quality characteristics of the individual and the psychosocial factors after trauma have certain effects. Mental disorders caused by closed craniocerebral trauma are particularly common, and open brain injury is closely related to long-term or chronic mental disorders. The heavier the traumatic brain injury, the greater the chance of developing a mental disorder and the longer it lasts. Consciousness disorder is closely related to the damage of the diencephalon and brainstem reticular activation system. The frontal and temporal lobe lesions are prone to personality changes and psychotic symptoms.

Diagnose based on:

(1) First of all, to determine whether there is brain trauma. Understand the detailed history before and after trauma, including the time, cause, nature, degree of injury, presence or absence of consciousness, duration of disturbance of consciousness and accompanying symptoms. In the event of a work-related accident, a traffic accident, or a traumatic brain injury in a daily life dispute, it is more appropriate to be cautious in dealing with personnel relations and compensation issues. In addition to the patient's self-report, there should be circumstantial evidence, including detailed records of the doctor's rash at that time. Or invite a surgical or neurosurgeon to consult, unless there is a diagnosis of brain trauma, do not easily diagnose the sequela of brain injury.

(B) detailed neurological examination: there are no limitations of physical signs.

(3) Auxiliary examination: brain ultrasound (positive lateral position, skull base) brain ultrasound diagnosis, EEG, brain CT examination and psychological test.

(4) Exclusion of various neurosis: schizophrenia, affective disorder, pathological personality, chronic subdural hematoma and other mental disorders caused by brain organic diseases.

Differential diagnosis

In the differential diagnosis, attention is distinguished from neurosis, schizophrenia and bipolar disorder. Other brain organic diseases that cause the corresponding mental disorders should also be excluded.

Neurosis: The patient has reduced mental activity, often has anxiety and annoyance, or suffers from various physical discomforts. Physical examination cannot find brain organic disease or physical disease as the basis of his clinical symptoms; self-knowledge Mostly good, no persistent psychotic symptoms; usually do not confuse their morbid experience with objective reality, that is, the patient's actual ability to test is ultimately compromised; behavior generally remains within the limits of social norms, can be understood and accepted by others Often urgently demanding treatment. The onset is mostly related to quality, personality characteristics or mental stress; the course of disease is prolonged or episode. The course of the disease is less than 3 months or there is a short time for the author to call a neurotic reaction.

Neurosis depression: Depressive neurosis, also known as neuropathic depression, is caused by psychosocial factors and is often related to the patient's personality deviation; it is a neurotic disorder characterized by persistent low mood; There are anxiety, physical discomfort and sleep disorders. The patient has treatment requirements, but there is no obvious motor inhibition or hallucinations, delusions, and life work is not seriously affected.
