![]() Other common causes of pontine stroke include diseases that affect the arteries such as small artery disease, large artery atherosclerosis (when the arteries become thickened with plaque), and cardiogenic emboli (when a blood clot travels from the heart to the brain). Hypertension and diabetes are two of the most common risk factors for all ischemic strokes and especially lacunar infarcts, a type of ischemic stroke that occurs in the deep areas of the brain such as the pons. Pontine strokes make up approximately 7% of all ischemic strokes (pontine infarct) and 10% of hemorrhagic strokes. Pontine strokes can be classified as either ischemic or hemorrhagic.Īn ischemic stroke occurs when an artery in the brain becomes blocked by a blood clot, while a hemorrhagic stroke occurs when an artery in the brain bursts. ![]() Use the links below to jump straight to any section about pontine stroke:Ī pontine stroke refers to a stroke within the pons, the largest component of the brain stem. This article will even include a rare success story of a survivor with locked-in syndrome that partially recovered. In severe cases, a pontine stroke can result in a rare condition called locked-in syndrome where the entire body except for the eyes become paralyzed.įortunately, when a stroke only affects one side of the pons (unilateral pontine stroke), the prognosis is generally good and some survivors can even achieve a full recovery with timely treatment and rigorous rehabilitation. When the disruption is caused by a blood clot in particular, it’s referred to as a pontine infarction or pontine infarct.Īs signals responsible for the body’s motor control flow through the pons, a common effect of a pontine stroke is hemiparesis, or weakness on one side of the body. When blood flow to the pons becomes interrupted, it causes a pontine stroke or pons stroke. The pons is the largest component of the brain stem.
