One of the most common symptoms associated with cerebrovascular disease is a sudden, severe headache, which can indicate a subarachnoid hemorrhage (SAH) due to a ruptured aneurysm. This headache is often described as the worst headache of one's life and is usually accompanied by nausea, vomiting, and a rapid decline in consciousness.
In the case of an ischemic stroke, which occurs when a blood clot obstructs a vessel supplying blood to the brain, symptoms can develop suddenly and may include weakness or numbness on one side of the body, difficulty speaking or understanding speech, and vision problems in one or both eyes. Patients might also experience sudden confusion, trouble walking, dizziness, and a loss of balance or coordination. These symptoms reflect the brain's areas that have become deprived of oxygen and nutrients due to the blocked blood flow.
Transient ischemic attacks (TIAs), often referred to as mini-strokes, present similar symptoms to ischemic strokes but are temporary and typically resolve within minutes to hours. TIAs serve as warning signs of potential future strokes and should be taken seriously, warranting immediate medical attention to prevent more severe episodes.
Symptoms of hemorrhagic strokes, caused by bleeding in or around the brain, can include sudden, severe headaches, nausea, vomiting, and loss of consciousness. Patients may also experience weakness or numbness, particularly on one side of the body, difficulty speaking, and visual disturbances. The onset of these symptoms is often abrupt, requiring urgent medical intervention to prevent further brain damage and complications.
For conditions like hereditary hemorrhagic telangiectasia (HHT), symptoms can include recurrent nosebleeds, visible small blood vessels on the skin and mucous membranes, and arteriovenous malformations (AVMs) in the brain that can lead to headaches, seizures, and neurological deficits if they bleed.
