By Steve Bressert, Ph.D. Narcissistic Personality Disorder is a disorder that is characterized by a long-standing pattern of grandiosity (either in fantasy or actual behavior), an overwhelming need for admiration, and usually a complete lack of empathy toward others.
Idiopathic sensory-motor polyneuropathy is an illness where sensory and motor nerves of the peripheral nervous system are affected and no obvious underlying etiology is found. In many respects, the symptoms are very similar to diabetic polyneuropathy.
A number of different disorders may cause polyneuropathy, including diabetes and some types of Guillain-Barre barrÃ©. Syndrome sensory polyneuropathy is the condition of having multiple sensory, neuropathies while motor polyneuropathy refers to multiple motor. neuropathies Myelinopathy, or demyelinating polyneuropathy, is due to a loss of myelin (or of the Schwann cells that make and contain it). 2  This demyelination slows down or completely blocks the conduction of action potentials through the axon of the nerve cell.
