Cerebral embolism

From WikiMD's Wellness Encyclopedia

Cerebral Embolism is a neurological disorder that occurs when a blood clot, also known as an embolus, is formed in one part of the body and travels through the bloodstream to the brain. This can lead to a stroke if the clot blocks a blood vessel in the brain, preventing oxygen and nutrients from reaching the brain cells.

Causes[edit | edit source]

The most common cause of a cerebral embolism is atrial fibrillation, a heart condition that causes the heart to beat irregularly. Other causes can include heart disease, infection, and cancer. In some cases, a cerebral embolism can occur as a result of a medical procedure or surgery.

Symptoms[edit | edit source]

Symptoms of a cerebral embolism can vary depending on the area of the brain that is affected. Common symptoms can include sudden numbness or weakness in the face, arm, or leg, especially on one side of the body, confusion, trouble speaking or understanding speech, difficulty seeing in one or both eyes, and severe headache with no known cause.

Diagnosis[edit | edit source]

Diagnosis of a cerebral embolism typically involves a physical examination, a review of the patient's medical history, and imaging tests such as a computed tomography (CT) scan or magnetic resonance imaging (MRI) to view the brain and detect any blockages.

Treatment[edit | edit source]

Treatment for a cerebral embolism aims to remove or dissolve the clot, restore blood flow to the brain, and prevent further clots from forming. This can involve medication, surgery, or other procedures. In some cases, rehabilitation may be needed to help the patient recover lost skills or learn new ways of performing tasks.

Prevention[edit | edit source]

Prevention of cerebral embolism often involves managing risk factors such as high blood pressure, diabetes, and high cholesterol. Lifestyle changes such as regular exercise, a healthy diet, and quitting smoking can also help reduce the risk.
