What is a capsular infarction?

A capsular infarction is a type of stroke that affects the internal capsule, a collection of nerve fibers that connects the cerebral cortex to the brainstem. It is an ischemic stroke, meaning that it is caused by a lack of blood flow to the brain.

Capsular infarctions can occur in either the anterior or posterior limb of the internal capsule. Anterior limb infarctions are more common and tend to cause motor deficits, while posterior limb infarctions can cause sensory deficits.

Symptoms of a capsular infarction can include:

* Sudden weakness or paralysis on one side of the body

* Difficulty speaking or understanding speech

* Difficulty swallowing

* Vision problems

* Sensory loss on one side of the body

* Confusion or memory loss

Capsular infarctions are a serious medical condition and can lead to permanent disability. Treatment typically involves medications to improve blood flow to the brain, surgery to remove the blockage, and rehabilitation therapy to help the person recover function.
