What is Conduction velocity of nerves is NOT affected by which of the following? and explain in detail?
Motor neuron disease is at anterior horn cell, pyramidal neurons and not the nerves. Thus the conduction velocity in the nerves is normal. Leprosy - Affects nerves and both sensory nerve conduction /motor nerve conduction studies may demonstrate reduced amplitude in affected nerves but occasionally may reveal demyelinating features. Charcot-Marie-Tooth disease (CMT) -MC hereditary neuropathy and has reduced motor nerve conduction velocity A.I.D.P -Segmental demyelination in the spinal cord and peripheral nerves. Early features-prolonged F-wave latencies Prolonged distal latencies Reduced amplitudes of compound muscle action potentials, d/t involvements of nerve roots and distal motor nerve terminals
