What should I do if I hit my head and experienced memory loss?

Amnesia symptoms after head trauma, medically referred to as traumatic brain injury (TBI) or concussion, should be managed with a comprehensive approach: 1. **Emergency medical care**: Seek immediate medical attention for thorough examination to rule out serious complications such as intracranial hemorrhage. 2. **Medication treatment**: According to the physician's advice, medications such as mecobalamin dispersible tablets, vitamin B12 tablets may be used to promote nerve recovery; nootropic agents such as oxiracetam capsules, sodium citicoline capsules may be used to improve cerebral metabolism and brain function. 3. **Rehabilitation therapy**: Once the condition stabilizes, patients may require physical therapy, speech therapy, and occupational therapy to help restore impaired functions. Traditional Chinese medicine treatments such as acupuncture and massage may also help promote blood circulation and alleviate amnesia symptoms. 4. **Daily management**: Maintain good lifestyle habits and engage in appropriate physical exercise, such as swimming and hiking, to enhance physical fitness and relieve stress. Pay attention to nutritional diet, and consume more foods rich in protein and vitamins, which are beneficial for the recovery of brain nerve function.
