Q

Who is risk for Post-Polio Syndrome

A

Polio is a contagious (viral) disease. Only a polio survivor can develop Post-Polio Syndrome. An estimated 25-40% of polio survivors develop PPS.

Q

What causes Post-Polio Syndrome

A

The new weakness appears to be related to the degeneration of individual nerve terminals and the muscle fibers it activates. Body compensates by creating new nerve-end terminals. Over time motor neurons lose the ability to maintain the increased work demands.

Q

Pathophysiology of Parkinson’s Disease

A

[] A degenerative disease of the motor systems of the brain.
[] Progressive cell loss is noted in the substantia nigra, which carry major connections to the basal ganglia.
[] Also kills dopaminergic neurons, noradrenergic neurons, & cholingergic neurons. This produces a cellular abnormality called Lewy Bodies inside the neurons.
