Mild concussion usually leads to retrograde amnesia and transient consciousness disturbances in patients after the injury. Patients may also experience headaches, dizziness, loss of appetite, decline in memory, and lack of concentration. To alleviate mild concussion, it is important to first ensure that the patient gets adequate rest, avoids staying up late, and maintains a quiet environment. Secondly, it is essential to pay attention to the patient's nutritional needs, adopting a light and easily digestible diet. Thirdly, symptomatic medical treatment should be considered, especially if the patient suffers severely from headaches, nausea, loss of appetite, or insomnia. In such cases, analgesic and hypnotic medications can be used to relieve symptoms.
