A vascular headache is an outdated term to describe certain types of headache which were thought to be related to blood vessel swelling and hyperemia as cause of pain. [ citation needed ] There is no doubt that some headaches are caused by vascular effects.
Arteritis is a vascular disorder characterized by inflammation of the walls of arteries, [1] usually as a result of infection or autoimmune responses. Arteritis, a complex disorder, is still not entirely understood. [2] Arteritis may be distinguished by its different types, based on the organ systems affected by the disease. [2]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
These headaches are typically bilateral, very severe and peak in intensity within a minute. [1] They may last from minutes to days, and may be accompanied by nausea, photophobia, phonophobia or vomiting. [1] Some patients experience only one headache, but on average there are four attacks over a period of one to four weeks. [1]
Diminished or absent pulses, vascular bruits, hypertension, Takayasu retinopathy, and aortic regurgitation. [9] Giant cell arteritis: Headache, scalp tenderness, jaw claudication, and blindness. [10] Primary medium vessel vasculitis [8] Polyarteritis nodosa: Mononeuritis multiplex, nodules, purpura, livedo, and hypertension. [11] Kawasaki disease
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e ...
Vascular disease is a class of diseases of the vessels of the circulatory system in the body, including blood vessels – the arteries and veins, and the lymphatic vessels. Vascular disease is a subgroup of cardiovascular disease .
Ischemia is the loss of blood flow to the focal region of the brain. This produces heterogeneous areas of ischemia at the affected vascular region, furthermore, blood flow is limited to a residual flow. Regions with blood flow of less than 10 mL/100 g of tissue/min are core regions (cells here die within minutes of a stroke).
