Cerebral atrophy is a chronic disease, divided into physiological brain atrophy and pathological brain atrophy. The exact duration of life cannot be generalized, but needs to be analyzed in the context of individual conditions. Physiological brain atrophy refers to the natural aging that occurs with age and is a normal manifestation of human aging. For people over 60 years old, there is often physiological brain atrophy, which does not require drug intervention and does not affect life expectancy. In the case of pathological brain atrophy, which is often related to certain diseases, treatment is more difficult and usually only symptomatic with relevant medications. For example, pathological brain atrophy caused by degenerative brain diseases can manifest as memory impairment and dementia, etc. The prognosis for such patients is poor and their life expectancy is short. For patients with underlying diseases such as hypertension, diabetes and hyperlipidemia, active treatment is recommended to control blood pressure, blood sugar and blood lipids to the ideal state to prevent serious complications.
