– A brainstem stroke is a type of stroke that affects the brainstem, which is the part of the brain that connects the cerebrum (the upper part of the brain) with the spinal cord.
– The brainstem controls many vital functions, such as breathing, heartbeat, blood pressure, eye movements, swallowing, and speech.
– A brainstem stroke can occur when the blood supply to the brainstem is interrupted by a clot or a bleed in one of the arteries that supply this region.
– The discovery of brainstem stroke is not well documented, but it is likely that it was first recognized by neurologists in the late 19th and early 20th centuries, who described various syndromes associated with lesions in different parts of the brainstem. Some of these syndromes are named after the neurologists who first reported them, such as Weber's syndrome, Benedikt's syndrome, Claude's syndrome, Foville's syndrome, Wallenberg's syndrome, and others. These syndromes are characterized by specific combinations of symptoms that reflect the location and extent of damage in the brainstem.
🔅 Symptoms that indicates one maybe suffering from a brainstem stroke
– A brainstem stroke can cause serious and life-threatening symptoms, such as:
1) Weakness or numbness on one side of the face or body.
2) Double vision or loss of vision.
3) Dizziness, vertigo, or loss of balance.
4) Slurred speech or difficulty swallowing.
5) Decreased level of consciousness or coma.
6) Locked-in syndrome, a condition in which a person is fully aware but cannot move or communicate except by eye movements.
🔅 Causes of brainstem stroke
– The causes of brainstem stroke are similar to those of other types of stroke, such as high blood pressure, diabetes, heart disease, atrial fibrillation, smoking, and high cholesterol.
– However, some rare causes of brainstem stroke include: injury to an artery due to sudden head or neck movements, infection or inflammation of the blood vessels (vasculitis), or genetic disorders that affect the blood vessels (such as Moyamoya disease).
🔅 Diagnosis and treatment of brainstem stroke
– The treatment of brainstem stroke depends on the type and severity of the stroke.
– If the stroke is caused by a clot (ischemic stroke), then the first step is to dissolve or remove the clot and restore blood flow to the brain. This can be done by administering clot-busting drugs (such as tissue plasminogen activator or tPA) intravenously or by performing a mechanical thrombectomy (a procedure that uses a catheter and a device to extract the clot). These treatments are most effective if given within a few hours of the onset of symptoms.
– If the stroke is caused by a bleed (hemorrhagic stroke), then the first step is to stop the bleeding and reduce the pressure in the brain. This can be done by administering drugs that lower blood pressure and prevent further bleeding (such as antihypertensives and anticoagulants) or by performing surgery to evacuate the blood and repair the damaged blood vessel.
🔅 Recovery and prognosis
– The recovery and prognosis of brainstem stroke vary depending on the location and extent of damage in the brainstem, as well as the age and overall health of the patient. Some patients may recover fully or partially from their symptoms, while others may have permanent disabilities or die from their stroke.
– The rehabilitation process may involve physical therapy, occupational therapy, speech therapy, and psychological support to help patients regain their functions and cope with their condition. Some patients may also need long-term care and assistance with their daily activities.
🔅 Preventive measures for a brainstem stroke
– The prevention of brainstem stroke involves reducing the risk factors that can cause stroke in general, such as:
• Controlling blood pressure, blood sugar, and cholesterol levels.
• Quitting smoking and avoiding exposure to secondhand smoke.
• Eating a healthy diet that is low in fat, salt, and sugar and high in fruits, vegetables, and fiber.
• Exercising regularly and maintaining a healthy weight.
• Limiting alcohol intake and avoiding illicit drugs.
• Managing stress and practicing relaxation techniques.
• Taking medications as prescribed by your doctor.
• Seeking medical attention promptly if you experience any signs or symptoms of stroke.
• Lastly, consult with your healthcare provider if you notice the aforementioned symptoms for a check up.
