Cerebrovascular Disease Quiz

Study Notes

Symptoms of Stroke

Sudden onset of weakness or numbness on one side of the body is a typical symptom of an acute stroke.
Difficulty speaking or understanding speech, known as aphasia, may occur during a stroke.
Visual disturbances, such as sudden blurred or decreased vision in one or both eyes, can indicate a stroke.

Congenital Cerebrovascular Disease

A form of congenital cerebrovascular disease can include arteriovenous malformations (AVMs), which are abnormal connections between arteries and veins.

Risk Factors for Stroke

Atrial fibrillation is the major risk factor for strokes caused by embolism, as it can result in blood clots forming in the heart.

Primary Risk Factor for Stroke

Hypertension (high blood pressure) is the most important contributing factor for stroke and cerebrovascular diseases, significantly increasing risk.

Presentations of Cerebrovascular Disease

Common presentations include transient ischemic attacks (TIAs), strokes, and chronic neurological deficits, like weakness or sensory loss.
Patients may experience cognitive deficits or changes in personality due to compromised blood flow.

Causes of Cerebrovascular Disease

Less common causes include conditions such as vasculitis and infections, while traditional causes involve atherosclerosis and hypertension.
Recognizing these differences is critical for diagnosis and treatment.

Hereditary Disorders and Aneurysms

Disorders like connective tissue diseases (e.g., Ehlers-Danlos syndrome) are associated with intracranial aneurysms, while certain hereditary disorders may not contribute to aneurysm risk.

Arterial Tears

The term "arterial dissection" defines tears in the internal lining of arteries, which can lead to ischemic events or stroke.

Risk Factors for Intracranial Aneurysms

Factors such as smoking and high blood pressure are recognized risks, while conditions like diabetes do not have conclusive associations with aneurysms.

Idiopathic Cerebrovascular Disorder

The term "Moyamoya disease" describes an idiopathic cerebrovascular disorder characterized by progressive narrowing and occlusion of intracranial blood vessels, leading to strokes.
