Concussion is a relatively mild form of traumatic brain injury. The main clinical manifestations are disturbances of consciousness, usually including disturbances such as unconsciousness, but typically not exceeding half an hour. There is also recent memory loss, and the inability to recall the incident causing the injury. Some patients may experience dizziness, headache, nausea, loss of appetite, insomnia, tinnitus, or difficulty concentrating and decreased memory. Additionally, a very small number of concussion patients might experience a low-grade fever.

Can you drink alcohol with a concussion?

Patients with concussions typically experience transient disturbances of consciousness after injury, such as coma, along with recent memory loss. Some also suffer from various degrees of headache, dizziness, nausea, vomiting, loss of appetite, insomnia, and other clinical symptoms. The diet for concussion patients should be light and easy to digest, avoiding spicy foods and other strong irritants, as well as avoiding alcohol, since alcohol can aggravate symptoms like headaches, dizziness, and insomnia. Therefore, patients with concussions should not drink alcohol.

How to administer first aid for a concussion

After a concussion occurs, the injured should be quickly moved from a dangerous environment to a safe area. The injured person should lie flat and rest quietly without sitting up or standing. The head can be appropriately cooled, and it is important to keep the body warm. For patients who are unconscious, it is necessary to keep the airway clear and closely observe their consciousness and pupils. If there are airway secretions or vomiting, they should be cleaned up promptly. If the patient has already experienced respiratory or circulatory problems, immediate cardiopulmonary resuscitation should be performed. After the aforementioned emergency treatment, the next step is to transport the patient to a nearby well-equipped hospital for further diagnosis and treatment.

How to alleviate a mild concussion

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.

Mild concussion symptoms

For patients with mild concussion, they often experience temporary loss of consciousness after suffering from violent blows, car accidents, falls from heights, and other accidental injuries, generally lasting no longer than 30 minutes. When patients regain consciousness, they may feel headaches, dizziness, nausea, vomiting, and have difficulty accurately recalling the incident, often referred to as retrograde amnesia. For such patients, cranial CT or MRI scans often show no significant positive signs, and it is suggested that no special treatment is necessary. Instead, patients should focus on rest, avoid overworking and exhaustion, and reduce excessive mental stimulation. The symptoms of most patients will gradually alleviate or even disappear within about two weeks.
