Cerebral blood supply insufficiency headache is only transient tension headache or spasmodic headache in mild cases, etc. In severe cases, when it develops into cerebral infarction, persistent recurring headache can occur. Cerebral insufficiency of blood supply is usually due to the narrowing of cerebral blood vessels, resulting in headaches caused by lack of oxygen to brain tissue. When cerebrovascular stenosis is mild, patients may feel a tightening sensation in the head, as well as dull pain and vascular-like throbbing headache in the bilateral frontal area and temple area. When cerebral blood supply insufficiency leads to cerebral vascular spasm, spasm-like pain in the head may occur, and the nature of headache may vary from person to person. Long-term cerebral blood supply insufficiency can cause cerebral white matter laxity, degeneration, and development of cerebral infarction, which may manifest as repeated dizziness, headache, and may be accompanied by memory loss, forgetfulness and other symptoms. When headache caused by insufficient cerebral blood supply occurs, you should consult a doctor in time to check the narrowing of cerebral blood vessels and decide on the treatment plan under the doctor’s guidance.
