multiple sclerosis
Inability to comprehend, auditory, visuals, spatial, or factory or other sensations, even though the sensory sphere is intact
agnosia
autoimmune condition that causes acute inflammation of the peripheral nerves damaging their mileage sheets, resulting increased nerve impulses, loss of reflux response, and setting muscle weakness also called infective or idiopathic polyneuritis
Guillain- Barré syndrome
