Brain overwork mainly refers to the process of prolonged or intense brain activity, because the products of brain cell metabolism accumulate in large quantities and are not obviously metabolized out, which will lead to the patient’s nutrient channels being blocked and blood circulation being poor, causing the activity of the cerebral cortex to be inhibited, which will have such a performance. Symptoms such as dizziness, headache, memory loss, lack of concentration, depression, irritability, poor appetite, fatigue and weakness, frequent yawning, and reduced responsiveness are all signs of brain fatigue. Some patients also have certain changes in mood and personality due to brain fatigue, for example, patients may be irritable and easily provoked, and patients’ calculation ability may be reduced.
