Code: 0 Organic mental disorder
Classification: (0) Organic mental disorder
(0) Organic mental disorder
Diagnostic criteria: Organic mental disorders are a group of mental disorders caused by brain diseases or physical diseases. Mental disorders caused by brain diseases include neurodegenerative diseases, cerebrovascular diseases, intracranial infections, brain injuries and brain tumors. Mental disorders caused by physical diseases are only part of the symptoms of primary physical diseases, and can also be collectively referred to as symptomatic mental disorders accompanied by infection and toxic mental disorders.
Symptom standard
(1) physical, nervous system and laboratory examination certificate;
(2) There are encephalopathy, brain injury, or physical diseases that can cause brain dysfunction, and at least the following 1 items: ① mental retardation syndrome; ② Amnesia syndrome; ③ Personality change; ④ Consciousness disorder; ⑤ Psychotic symptoms (such as hallucination, delusion, tension syndrome, etc.). ); ⑥ Emotional disorder syndrome (such as mania syndrome and depression syndrome). ); ⑦ Separation (transformation) syndrome; 8 neurosis-like syndrome (such as anxiety syndrome, emotional fragility syndrome, etc.). ).
Daily life or social function is seriously damaged.
The occurrence, development and course of mental disorders are related to primary organic diseases.
Exclusion criteria lack sufficient evidence to prove that mental disorders are caused by other reasons (such as psychoactive substances).

(00) Alzheimer's disease.
Code: 00 Alzheimer's disease.
Classification: (0) Organic mental disorder
(00) Alzheimer's disease.
Diagnostic criteria: Alzheimer's disease is a group of primary brain degenerative diseases with unknown etiology. Many diseases occur in the old age, the onset is hidden, and the progress is slow and irreversible (2 years or longer), mainly intellectual damage. Pathological changes were mainly cortical diffuse atrophy, sulcus gyrus widening, ventricular enlargement, a large number of neurons, senile plaques, neurofibrillary tangles, granular vacuoles and other diseases, and the contents of choline acetylase and acetylcholine decreased significantly. Most patients who started to get sick before the age of 65 have a family history of the same disease, and the lesions develop rapidly, especially in the temporal lobe and parietal lobe, which often leads to aphasia and apraxia.
Symptom standard
(1) conforms to the diagnostic criteria of organic mental disorder;
(2) Comprehensive mental retardation;
(3) There was no sudden stroke-like attack and no signs of focal nervous system damage in the early stage;
(4) No clinical or special examination suggests that mental disorder is caused by other physical or brain diseases;
(5) The following features can support the diagnosis, but they are not necessary: ① The function of higher cortex is impaired, which may lead to aphasia, agnosia or apraxia; 2 indifference, lack of active activities, or irritability, social behavior out of control; ③ Parkinson's symptoms and seizures may occur in advanced severe cases; ④ Physical, nervous system or laboratory examination proved that there was brain atrophy;
(6) Autopsy or neuropathological examination is helpful for diagnosis.
Serious standards, daily life and social functions are obviously damaged.
According to the slow course of the disease, the development of the disease can be suspended, but it is difficult to reverse.
Exclusion criteria exclude mental retardation caused by brain organic diseases such as cerebrovascular disease, mental retardation caused by mental disorders such as pseudodementia and depression, or benign amnesia of the elderly.
This indicates that dementia with Alzheimer's disease can coexist with vascular dementia. If the attack of cerebrovascular disease is superimposed on the clinical manifestations and medical history of Alzheimer's disease, it can cause a sudden change of mental disorder symptoms. These cases should be diagnosed (and coded) in a dual way. If vascular dementia occurs before Alzheimer's Harmo's disease, the diagnosis of Alzheimer's Harmo's disease may not be made according to the clinical manifestations.

ICD code: F00.9
(0 1) Mental disorders caused by cerebrovascular diseases
Code: 0 1 Mental disorder caused by cerebrovascular disease
Classification: (0) Organic mental disorder
(0 1) Mental disorders caused by cerebrovascular diseases
Diagnostic criteria: on the basis of cerebrovascular wall lesions, combined with changes in blood composition or hemodynamics, it leads to cerebral hemorrhage or ischemia, leading to mental disorders. Generally, the progress is slow, the course of disease is fluctuating, and the condition is often aggravated by stroke. When the compensation is good, the symptoms can be alleviated, so the clinical manifestations are varied, but in the end they often develop into dementia.
Symptom standard
(1) conforms to the diagnostic criteria of organic mental disorder;
(2) The distribution of cognitive defects is uneven, some cognitive functions are obviously impaired, some are relatively preserved, such as memory is obviously impaired, while judgment, reasoning and information processing are only slightly impaired, and insight can be well maintained;
(3) Personality is relatively complete, but some patients have obvious personality changes, such as egoism, paranoia, out of control, indifference or irritability;
(4) There is at least 1 evidence of focal brain injury: history of stroke, spastic paralysis of unilateral limb, positive plantar extension reflex, or pseudobulbar palsy;
(5) the history, examination or laboratory evidence of cerebrovascular disease;
(6) Autopsy or pathological examination of cranial nerves is helpful for diagnosis.
Serious standards, daily life and social functions are obviously damaged.
The occurrence, development and course of mental disorders are related to cerebrovascular diseases.
Exclusion criteria exclude consciousness disorder caused by other reasons, intellectual disorder caused by other reasons (such as Alzheimer's disease), emotional and mental disorder, mental retardation and subdural hemorrhage.
It shows that the mental disorder caused by cerebrovascular disease can coexist with Alzheimer's disease dementia, and when the clinical manifestations of Alzheimer's Harmo disease overlap with the onset of cerebrovascular disease, they can be diagnosed side by side.

ICD code: F0 1.0
Code: 0 1.2 Mental disorders caused by cortical vascular diseases
Classification: (0) Organic mental disorder
(0 1) Mental disorders caused by cerebrovascular diseases
Diagnostic criteria: the disease usually begins at the age of 50 ~ 60, and about half of them are complicated with hypertension, mainly with the deterioration of intelligent steps. It can suddenly or gradually develop after a short ischemic attack. Cerebral infarction caused by cerebrovascular diseases often causes mental retardation. Generally, atherosclerosis of carotid intima leads to the shedding of microemboli, which leads to the infarction of cerebral arterioles. Infarction is usually small and usually progresses slowly. Stroke attacks are often caused by cerebral hemorrhage, cerebral infarction or cerebral thrombosis, which leads to acute aggravation and fluctuation of course. Therefore, the patient may have a short history of multiple cerebral ischemia and stroke, and the symptoms and signs of the nervous system are limited, such as transient paraplegia, aphasia and visual impairment. Mental symptoms are varied, mental retardation is limited for a long time, and eventually it develops into complete dementia. There are often many small lacunar infarcts in brain tissue.
diagnostic criteria
(1) conforms to the diagnostic criteria of mental disorders caused by cerebrovascular diseases;
(2) Evidence of cerebrovascular disease, such as multiple ischemic stroke, localized nervous system damage and brain imaging, such as CT and MRI.
(3) After several small ischemic attacks in brain parenchyma, mental damage gradually appeared. In the early stage, it is a limited mental disorder with relatively complete personality, and in the later stage, it changes personality and develops into comprehensive dementia;
(4) The onset is slow, the course of disease is fluctuating or stepped, and there may be a period of clinical improvement, which usually develops into dementia within 6 months.
Description includes dementia with multiple cerebral infarction.
