Most of the patients with symptoms such as headache, inability to open eyes and sleepiness belong to cerebrovascular diseases. Due to lesions and hardening of blood vessels in the brain, thickening of blood vessel walls and narrowing of blood vessel lumens, resulting in poor blood flow, the brain suffers from ischemia and lack of oxygen. In this case, patients will experience drowsiness, accompanied by headache, and in severe cases, nausea and vomiting may also occur. In some patients, cervical spine disease is caused by the nerves and blood vessels that are compressed by the protruding lesions of the joints in the neck. This condition will also lead to poor blood flow, the brain suffers from ischemia and hypoxia, and symptoms of drowsiness and headache will occur. In severe cases, it will be accompanied by numbness in the arms, numbness in the fingers, and there may also be dizziness. In this case, one should go to a regular hospital to have a CT of the head, CT of the neck and routine blood tests to clarify the cause of the disease. Patients must avoid taking any medication themselves during this period to avoid medication errors.
