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.
Peripheral neuropathy is nerve damage in motor and sensory nerves that leads to pain, numbness and weakness. Many different conditions, infections, poisonous substances and forms of trauma can cause neuropathy. A patient should be aware of the side effects of neuropathy and know when to seek treatment.
