Neuropathy means damage to the nerves. The nervous system
consists of the central nervous system (CNS), which is comprised
of the brain and the spinal cord, and the peripheral nervous
system (PNS), which consists of the nerves connecting the CNS to
the organs and muscles.  Damage to the nerves in the PNS is
termed peripheral neuropathy. As this normally affects the
nerves that control the senses, such as touch and pain, it is
often termed 'sensory neuropathy'. However, the PNS includes the
autonomic nervous system which controls body functions such as
blood flow to internal organs, emptying of the stomach and
bladder. Damage to these nerves is called autonomic neuropathy.
