Poor memory in children may be related to various factors, including malnutrition, lack of exercise, and insufficient sleep. Treatment methods include supplementing trace elements, improving cognitive function with ingredients such as neurotrophins and brain activators, and cooperate with long-term persistent rehabilitation training. However, these treatments may bring significant mental and economic pressure to families and patients, and their efficacy is uncertain. Parents should pay attention to their child’s condition in a timely manner and take them for proper treatment to alleviate the progression of the disease.
