Brain atrophy, a condition commonly seen in middle-aged and elderly patients, leads to a decline in memory, resulting in symptoms such as forgetfulness, insomnia, and poor mental health. Mild brain atrophy can gradually improve through the use of drugs that nourish brain cells and regular functional exercise. It is advisable to regularly choose drugs that nourish brain cells, eat foods like walnuts, sunflower seeds, and avocados, and engage in intellectual exercises, such as playing chess or playing games that develop intelligence, all of which are effective in treating brain atrophy.
