Q. Why does internal capsule hemiplegia called dense hemiplegia?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Internal capsule hemiplegia, also known as dense hemiplegia, is a type of paralysis caused by damage to the internal capsule in the brain. This can be due to stroke, trauma or other causes. With this type of paralysis, all motor pathways from one side of the body (the affected hemisphere) are completely blocked. The result is complete paralysis on that side of the body without any sensory deficits or loss of consciousness; it is thus considered “dense” because no communication between parts of that hemisphere can occur.
The internal capsule contains nerve fibers traveling from various regions located around it in both directions and helps direct motor signals along certain pathways within the brain itself (known as transcallosal fibers). Damage to these fibers interrupts their transmission and leads to symptoms such as weakness, lack of coordination, brief pauses in movement and/or speech, difficulty maintaining balance when walking/moving and muscle atrophy over time – all classic signs associated with dense hemiplegia. As mentioned before, there may be some severe complications resulting from this condition including permanent disability or even death depending on severity.
To diagnose internal capsule hemiplegia doctors typically use MRI scans combined with highly precise tests like diffusion-weighted imaging which make tissue damage visible while providing precise information about its effects upon neurons within affected sections – allowing them to determine whether underlying issues have been caused by strokes or tumors for example. Treatment plans normally involve physical therapy aimed at restoring movement as much as possible but medications like anticoagulants (to prevent further blood clotting) may also be prescribed if necessary alongside lifestyle changes recommended for improving overall quality-of-life!
