Cerebrovascular Disorders

Learn what causes cerebrovascular disorders, the symptoms, diagnosis, and treatments available to improve your quality of life.


Cerebrovascular disorders are a group of diverse and complex neurological diseases which affect the arteries of the brain. These disorders can range from mild to severe and have the potential to cause significant disability and even death. In this review, we will discuss the pathophysiology of cerebrovascular disorders in detail, including common risk factors, pathological processes, and the physiological consequences of these disorders.

Risk Factors for Cerebrovascular Disorders

Cerebrovascular disorders are caused by a variety of risk factors, the most common of which are age, gender, race, and genetics.

Age is a major risk factor for cerebrovascular disorders, as the prevalence of these disorders increases with age. The risk is highest in individuals over the age of 65.

Gender is also a risk factor for cerebrovascular disorders, with men being more likely to develop these disorders than women.

Race is also a factor, with African Americans and Hispanics having a higher risk of developing these disorders than other racial groups.

Genetics can also play a role in the development of cerebrovascular disorders. The presence of certain genetic mutations, such as those related to clotting factors, can increase the risk of developing these disorders.

Other risk factors for cerebrovascular disorders include high blood pressure, high cholesterol, diabetes, smoking, and alcohol abuse.

Pathological Processes of Cerebrovascular Disorders

The pathological processes of cerebrovascular disorders are complex and varied, but can generally be divided into two categories: arterial ischemia and hemorrhagic stroke.

Arterial ischemia occurs when the arteries supplying blood to the brain become narrowed or blocked due to a buildup of plaque, a clot, or a tear in the artery wall. This causes a decrease in blood flow to the brain, leading to a lack of oxygen and nutrients, which can damage or even kill brain cells.

Hemorrhagic stroke occurs when a weakened artery wall ruptures and bleeds into the brain. This can cause swelling and pressure in the brain, which can lead to permanent damage or death.

Physiological Consequences of Cerebrovascular Disorders

The physiological consequences of cerebrovascular disorders vary depending on the severity of the disorder and the area of the brain affected.

For mild cases, symptoms may include headache, dizziness, confusion, and difficulty speaking or understanding speech.

For more severe cases, symptoms may include paralysis, seizures, coma, and even death.

In addition to these physical symptoms, cerebrovascular disorders can also have a significant psychological impact, leading to depression, anxiety, and other psychological issues.


In conclusion, cerebrovascular disorders are a group of complex and diverse neurological diseases which can have severe consequences for those affected. Risk factors for these disorders include age, gender, race, genetics, and lifestyle factors such as smoking and alcohol abuse. The pathological processes of these disorders include arterial ischemia and hemorrhagic stroke, and the physiological consequences can range from mild to severe, including paralysis, coma, and even death.
