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.
What is Polyneuropathy? Polyneuropathy, the most common form of a group of disorders known as peripheral neuropathy, is caused by damage to peripheral nerves (defined as all nerves beyond the brain and spinal cord). Peripheral nerves travel from the spinal cord to muscles, skin, internal organs, and glands.
