Brief memory loss after a head impact is caused by brain cell injury. This condition is primarily considered a mild concussion. The main symptom of concussion is a relatively mild level of impaired consciousness. Individuals with severe symptoms should seek medical attention at a hospital. Avoid spicy and stimulating foods, refrain from greasy foods, avoid strenuous exercise, get adequate rest, and maintain a positive and relaxed mood.
