What happens if the brain shrinks? Why does brain atrophy occur?

The clinical manifestations of cerebral atrophy can be divided into two categories: cerebral function decline and cognitive decline, which are mainly related to the location and degree of cerebral atrophy. Diffuse cerebral cortex atrophy is mainly characterized by dementia, mental retardation, memory impairment, personality changes, and behavioral disorders. Some are accompanied by hemiplegia and seizures.

Focal brain atrophy is dominated by personality and behavioral changes; Cerebellar atrophy is dominated by speech impairment, limb ataxia, and intention tremor.

1.Systemic symptoms.

In the early stage of the lesion, patients often experience dizziness and headache, insomnia and dreams, soreness in the waist and knees, numbness in the hands and feet, tinnitus and deafness, and gradually become sluggish, slow in movement, muttering, and answering questions that are not answered. In the physical aspect, it is often manifested as senile state of the dragon, white teeth, dryness, pigmentation, or hemiplegia, epilepsy, ataxia, tremor, etc., and neurological symptoms may or may not be present.

2.Memory impairment.

Memory loss of recent events occurs earlier, such as frequent loss of objects and forgetting promised things. As the disease progresses, it gradually leads to complete loss of memory.

3.Changes in personality behavior.

Personality changes are often an early symptom of the disease, with people becoming depressed and disliking people; or manifested as a lack of ideals, desires, and feelings for children and relatives; or have rigid and bizarre living habits, impatient personality, increased speech or verbosity, suspicious and selfish; or have a special concern for their own health and safety, often entangled by some minor discomfort; or amnesia or mania, with delusions, visual hallucinations, auditory hallucinations, aphasia, and agnosia. All high-level emotional activities, shame, responsibility, honor, and morality are reduced to varying degrees, and sleep rhythm changes may also occur.

4.Mental retardation, dementia.

It is manifested as an overall decline in intellectual activities such as comprehension, judgment, and calculation ability, unable to adapt to social life, and difficult to be competent for work and household chores; Gradually, I can't correct my name, age, I don't know how to eat and I don't know how to get hungry, I don't know how to return after going out, and I collect waste paper and miscellaneous items as treasures. In the later stage of the disease, he was bedridden all day long, unable to take care of himself, did not care for himself, incontinent and urinary, slurred speech, slurred speech, and finally complete dementia.

Cerebral atrophy is a common disease in the elderly, and the common symptoms after the disease are memory loss, emotional instability, and the ability to bear thinking has also decreased, and attention is often inattentive. Therefore, we should pay special attention to daily life and prevent it in time, and now we will talk about the causes of brain atrophy.

1. There are 5 main reasons for cerebral atrophy, which are generally related to age, with the growth of age, many elderly people's physical functions will slowly decline, and it is easy to suffer from some cerebrovascular diseases, etc., these diseases are easy to lead to cerebral ischemia and hypoxia, and then the symptoms of cerebral atrophy appear.

2. Cerebral atrophy may also be caused by poisoning, and the common one is drug poisoning, which is mostly caused by improper drug taking or drug abuse. If you don't pay attention to your body in your daily life, you may also have alcohol poisoning, heavy metal poisoning, etc., which will lead to brain atrophy.

3. Brain atrophy may also be caused by trauma, such as brain injury, sequelae of cranial surgery, etc., which can easily lead to brain atrophy.

4. Many times cerebral atrophy is caused by other diseases, the common ones are degenerative diseases, such as multiple sclerosis, cerebrovascular diseases, etc., such as cerebral arteriosclerosis, cerebral insufficiency or cerebral infarction, etc., these diseases are caused by cerebral blood ischemia and hypoxia.

5. Brain atrophy may also be caused by endocrine metabolism abnormalities, such as hyperthyroidism, diabetes, hypoglycemia and hepatic brain, etc., which will cause adverse effects on the body, and then endocrine and metabolic disorders will occur, and symptoms of brain atrophy may occur if not relieved in time.

Brain atrophy has a great impact on health, and there will be many adverse symptoms after illness, so it is necessary to pay more attention to prevention and understand the causes. There are 5 main causes of cerebral atrophy, most of which are caused by age, poisoning or trauma, and other diseases in daily life, such as cerebrovascular diseases, which may lead to cerebral atrophy.

Cerebral atrophy is a pathological change caused by a variety of diseases, and can cause cerebral atrophy due to a variety of reasons, including cerebral atrophy caused by inflammation recovery, trauma, respiration, cardiac arrest and other reasons. In addition, Mycobacterium tuberculosis, cryptococcus and other bacterial infections, as well as viral infections can cause brain atrophy. The most common clinical cerebral atrophy is brain tissue changes caused by cerebrovascular disease, cerebral ischemia, cerebral insufficiency and other reasons, which is mainly manifested by the widening and deepening of the cerebral sulcus of the brain, accompanied by changes in brain quality.

Hello, cerebral atrophy refers to a phenomenon that causes organic lesions in the brain tissue itself to atrophy due to various reasons. Pathologically, the volume of brain tissue is reduced, the number of cells is reduced, and the ventricles and subarachnoid space are enlarged.

Brain atrophy is caused by multiple factors. Heredity, traumatic brain injury, stroke, encephalitis, meningitis, cerebrovascular malformation, brain tumor, long-term seizures, excessive smoking and alcohol, malnutrition, thyroid dysfunction, gas poisoning, alcoholism, cerebral arteriosclerosis, cerebral ischemia, hypoxia, etc. can cause destruction of brain parenchyma and atrophy, deformation and disappearance of nerve cells. The main cause of cerebral atrophy is long-term chronic ischemia of cerebral blood vessels, which leads to a decrease in the deformability of red blood cells, insufficient effective blood perfusion of microvessels, brain tissue is in a state of chronic ischemia and hypoxia, and the morphology and function of brain cells are affected, that is, brain atrophy is formed.

The pathological changes showed flattening of the cerebral gyrus, widening of the sulci, enlargement of the ventricula cistern, and loss of brain weight. Most of them are cerebral cortex atrophy. Due to the different atrophy sites and scopes, it can be divided into localized and diffuse cerebral atrophy, cerebellar, olivine, pontine atrophy, cortical and ** type atrophy.
