Alcoholic tremor is a common clinical symptom of alcoholic cerebral atrophy. Alcoholic cerebral atrophy refers to the irreversible reduction of brain tissue due to chronic alcohol consumption. It is controversial whether this disease constitutes an independent clinicopathological disorder. Some authors consider alcoholic cerebral atrophy to be a pathological concept, a term that first originated from studies of cerebral angiography. The term refers specifically to relatively young alcoholics with or without clinical signs of brain lesions, with brain imaging demonstrating enlarged lateral ventricles and widened frontal sulci. There are corresponding findings in modern imaging. A small amount of reasonable alcohol consumption may be beneficial, and avoiding long-term heavy drinking is the main measure to prevent brain atrophy due to alcoholism. The following points should be noted for the prevention of alcoholic tremor: 1. enhance nutrition, improve nutritional status, maintain dietary balance and psychological health; 2. read more books and newspapers, frequently participate in group activities and moderate participation in exercise; 3. enhance cognitive activities and try to recover previous life experiences and abilities.
