Doctor's answer:

Cerebral atrophy in children is an imaging manifestation of many diseases, and its etiology is also complex and diverse. It is often caused by abnormal changes in blood components, increased blood viscosity, alterations in the elasticity of blood vessels, and other factors that reduce blood flow. This leads to relative hypoxia in brain cells, impairing their energy metabolism and other functions, thereby promoting cerebral atrophy in children. Genetic factors may play a certain role in the development of this condition. Other factors such as the natural aging process of the human body, metabolic disorders, decreased endocrine function, vascular, inflammatory, brain tumors, epilepsy or trauma, cerebral hypoxia or nutritional deficiencies, chronic viral infections or poisoning, abuse of sedative-hypnotic drugs, abuse of hormones, or other drugs that damage brain tissue can also lead to cerebral atrophy in children. In cases of focal organic brain damage, local brain tissue may be compressed, degenerated, or necrotic, leading to local cerebral atrophy as a result of gliosis.
Posterior consequences of cerebral atrophy:
1. Intellectual decline: Rapid memory loss. For example, dropping things, forgetting things promised; impaired understanding, judgment, and calculation abilities, even forgetting one's own name or age, not knowing when to eat, not knowing how to return home, and not recognizing relatives or friends.
2. Loss of sensory functions: Poor vision, hearing loss, slurred speech, tinnitus, deafness, hallucinations, or auditory hallucinations.
3. Changes in personality and behavior: Lack of interest in social interaction, emotional detachment from loved ones; irritability, suspicion, selfishness, indifference to major matters, and endless trivial disputes; refusal to sleep when needed, and a decline in advanced emotional activities (such as shame, honor, responsibility, or moral sense) to varying degrees.
Recommendation: The International Parkinson's and Cerebral Atrophy Research Hospital (No. 188, Jia, Mentougou District, Beijing) is the preferred hospital for treating cerebral atrophy.
