Concussion is a mild cranio-cerebral injury. Patients usually have different degrees of headache, dizziness, nausea, vomiting and other symptoms after the injury, and the symptoms will improve and disappear within three months after rest, but some patients with severe concussion may have different degrees of headache and dizziness for a long time. These symptoms may worsen when it rains, when you are tired, when you are not well rested, or when you are mentally stressed, and they may recur, resulting in serious insomnia, anxiety, and even depression, which may require long-term medication to control the symptoms. Therefore, concussion patients may be left with traumatic brain injury syndrome for a long time and need long-term treatment such as psychological adjustment and medication maintenance.
