What happens if the internal capsule is damaged?
Damage to this area can affect functions like speaking, chewing, and swallowing. As a result, individuals may struggle to swallow (dysphagia), have difficulty with eating, and/or struggle with speech (dysarthria and other motor speech disorders) after an internal capsule stroke.
What does the internal capsule do in the brain?
The internal capsule describes a region deep in the brain that functions as a communication pathway. The internal capsule allows communication between areas of the cerebral cortex and areas of the brainstem.
What is the blood supply of internal capsule?
The internal capsule and basal nuclei are supplied by perforating branches of the anterior cerebral artery (ACA), Heubner’s artery, middle cerebral artery (MCA), internal carotid artery (ICA) and anterior choroidal artery (AChA).
What is inside internal capsule?
The internal capsule (IC) is a white matter structure composed of bundles of myelinated fibers that course past the basal ganglia. It is located in the inferomedial portion of each cerebral hemisphere and separates the caudate nucleus and thalamus from the lentiform nucleus.
Why is the internal capsule vulnerable to the damaging effects of adverse vascular events?
IC CVA. The internal capsule is prone to cerebrovascular accidents because the perforating arteries that supply the region are predisposed to occlusion or rupture due to their small diameter.
Where is the internal capsule of the brain?
What travels through internal capsule?
Introduction to the Exam for Internal Capsular Stroke The internal capsule, a white matter structure, is a unique location where a large number of motor and sensory fibers travel to and from the cortex.
What is internal capsule stroke?
Weakness of the face, arm, and/or leg (pure motor stroke) Known as one of the classic types of lacunar infarcts, a pure motor stroke is the result of an infarct in the internal capsule. Pure motor stroke caused by an infarct in the internal capsule is the most common lacunar syndrome.
