PATHOLOGIES
brain stem stroke
A brain stem stroke occurs when blood flow to the brain stem, the lower part of the brain that connects to the spinal cord, is interrupted due to a blockage (ischemic stroke) or bleeding (hemorrhagic stroke). The brain stem is crucial for controlling vital bodily functions such as breathing, heart rate, and consciousness. It also facilitates communication between the brain and body, as it houses many of the body’s motor and sensory pathways. A stroke in this area can have severe and widespread effects on the body.

Symptoms of a brain stem stroke can vary widely depending on the specific area affected. They may include dizziness, vertigo, double vision, slurred speech, difficulty swallowing, weakness or numbness in the arms or legs, loss of coordination, and difficulty breathing. In severe cases, a brain stem stroke can result in locked-in syndrome, where a person is conscious but unable to move or communicate except through eye movements.
Risk factors for brain stem strokes are similar to other strokes and include high blood pressure, diabetes, high cholesterol, smoking, obesity, and atrial fibrillation.
Diagnosis typically involves imaging tests such as CT scans or MRIs to determine the type and location of the stroke. Additional tests, such as carotid ultrasounds or echocardiograms, may identify underlying causes like blockages or clots.
Treatment depends on whether the stroke is ischemic or hemorrhagic. Ischemic strokes may be treated with clot-busting drugs (tPA) or mechanical thrombectomy to restore blood flow, while hemorrhagic strokes may require surgical intervention to stop bleeding and relieve pressure on the brain.
Recovery from a brain stem stroke can be challenging due to its critical role in bodily functions, but rehabilitation focused on physical, occupational, and speech therapy is essential for improving quality of life.
