Numerous medical diseases that have an impact on the brain's blood arteries and cerebral circulation are grouped under the umbrella term "cerebrovascular disease." In these conditions, the arteries that feed the brain with nutrients and oxygen are frequently harmed or distorted. An ischemic stroke, mini-stroke, and occasionally a haemorrhagic stroke are the most typical presentations of cerebrovascular illness. Due to its ability to alter blood vessel structure and cause atherosclerosis, hypertension is the main risk factor for stroke and other cerebrovascular illnesses. Because cerebral perfusion is reduced as a result of brain blood artery narrowing brought on by atherosclerosis. Smoking and diabetes are two more stroke risk factors.

Strokes that are ischemic can result from narrowed brain arteries, but haemorrhagic strokes can also be caused by persistently high blood pressure, which tears blood vessels.

Signs and symptoms

Acute strokes, which happen when the brain's blood flow is impaired, are the most typical presentation of cerebrovascular disorders. Stroke symptoms typically appear quickly and include vision abnormalities, balance issues, weakness on one side of the face or body, numbness on one side of the face or body, and difficulty speaking or understanding. An extremely intense, sudden headache, nausea, stiff neck, and a loss of consciousness can be symptoms of hemorrhagic strokes. The location and extent of the stroke's involvement will affect the symptoms. Brain swelling, or edema, can happen, raising intracranial pressure and possibly leading to brain herniation.

Migraines, epileptic seizures, cognitive impairment, and migraines are further signs of cerebrovascular illness. However, until an acute stroke develops, cerebrovascular illness may go unnoticed for years. Additionally, certain people with uncommon congenital cerebrovascular illnesses could start showing these symptoms as early as childhood [1-5].


Congenital: Congenital diseases are illnesses that can be inherited through genes or are afflictions that are present at birth. Congenital cerebrovascular illnesses include CADASIL, germinal matrix haemorrhage, and arteriovenous malformations (cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy).  Aberrant blood vessel tangles are known as arteriovenous malformations. Veins are typically protected from the increased blood pressure that occurs in arteries by a capillary bed that divides them from arteries. Because arteries and veins with arteriovenous malformations are joined directly, there is a higher chance of venous bleeding and rupture. Brain arteriovenous malformations have a 2-4% annual rupture risk. However, many arteriovenous malformations are asymptomatic and go undetected for the entirety of a person's life.

When frail blood arteries within a premature baby's germinal matrix break, it causes bleeding into the brain known as a germinal matrix haemorrhage. A highly vascularized region of the developing baby's brain called the germinal matrix is where neurons and glial cells are created. When a baby is born early, before 32 weeks, the chance of germinal matrix haemorrhages increases. Hemorrhage risk is increased by the stresses that are exposed after birth and by the blood vessels' fragility. Flaccid weakness, seizures, strange posture, or erratic breathing are examples of signs and symptoms.

The Notch 3 gene, which is on chromosome 19, is where mutations in the CADASIL hereditary condition are brought on. A transmembrane protein with an unknown function is encoded by the Notch 3 gene. The increase of this protein in tiny to medium-sized blood vessels is brought on by the mutation. Early onset of this disease in adults is frequently accompanied by headaches, stroke, depressive symptoms, and cognitive decline. White matter alterations in the brain and evidence of previous strokes are both seen on MRI. Gene testing can verify the diagnosis.

Idiopathic: Idiopathic illnesses are ones that develop suddenly and for no apparent reason. An illustration of an idiopathic cerebrovascular illness that causes cerebral blood arteries to constrict and occlude is moyamoya. Stroke or transient ischemic attack is the most typical manifestation, but children's cognitive deterioration may also be a presenting sign. Although some people may not have symptoms until age, the disease may start to manifest in youth.


There are several less frequent causes of cerebrovascular illness besides hypertension, such as congenital or idiopathic conditions such CADASIL, aneurysms, amyloid angiopathy, arteriovenous malformations, fistulas, and arterial dissections. Many of these illnesses can go unnoticed until an acute occurrence, like a stroke, takes place.

Seizures and headaches are less common symptoms of cerebral vascular disorders. Vascular dementia can be brought on by any of these conditions because they all cause ischemic brain damage.
