Concussions can cause dizziness as well as headaches and possibly transient brain dysfunction. A concussion is a brain dysfunction caused by a violent blow to the head. When the head is suddenly struck by an external force, the patient may experience a transient loss of consciousness or confusion, and after waking up, dizziness and headache may occur, and transient brain dysfunction may also occur, with changes in pupils, a drop in blood pressure, and respiratory disorders. There is no specific treatment for concussion, and the specific treatment depends on the severity of the concussion and the clinical symptoms. During the treatment period, it is necessary to avoid too strenuous exercise and pay attention to bed rest.
