Brain atrophy in the elderly is usually a physiological atrophy condition, while in a few cases it is a pathological atrophy caused by dementia and Parkinson’s disease. Treatment of cerebral atrophy is mainly based on medication to improve the symptoms of cerebral atrophy to slow down the development of the disease and eliminate the causes of cerebral atrophy. Symptomatic drugs are mainly applied to nourish brain nerves and brain cells to slow down the brain function and improve the condition of brain atrophy. The drugs include Olacitant capsule, cytarabine sodium capsule, aniracetam capsule, piracetam capsule, etc. The drugs applied for the treatment of the cause are more complicated. The main causative factor of cerebral atrophy is the morphological and functional damage of brain cells caused by chronic ischemia of brain tissue, so the drugs for causative treatment include antithrombotic drugs such as aspirin enteric tablets, lipid-lowering drugs such as atorvastatin calcium tablets, anti-atherosclerotic drugs such as probucol tablets, etc.
