Headache in the elderly may be a precursor of acute vertebrobasilar occlusion, cerebral arteritis, and tuberculous meningitis. 1. Acute vertebrobasilar artery occlusion: When acute vertebrobasilar artery occlusion occurs in elderly patients, insufficient blood supply to the brain tissues may be the precursor of dizziness and headache. 2. Cerebral arteritis: Cerebral arteritis is a kind of narrowing and occlusion of the lumen of cerebral arteries, ischemia and infarction of brain tissues in the blood-supplying area caused by factors such as infections, medicines or metabolic reactions, etc., and may appear as a precursor of headache. 3. Tuberculous meningitis: Tuberculous meningitis is a non-suppurative inflammatory disease of the meninges and spinal membranes caused by Mycobacterium tuberculosis. It is a non-suppurative inflammatory disease of the meninges and spinal membranes caused by Mycobacterium tuberculosis. It has an insidious onset and chronic course, or it can be acute or subacute, and patients may have headaches as precursors. When the elderly have headaches, they also need to consider the early symptoms of acute cerebrovascular disease, brain tumors, intracranial infections and other diseases, and they should go to the hospital in time for consultation and examination to avoid delaying the treatment time.
