Background
It was defined by IASP (International Association for the Study of Pain) in 1994 as a consequence of injury or disease affecting the somatosensory system.
So NP refers to pain that originates from injury or disfuncion of the nervous system,
including diseases of the peripheral or central nervous system.
The patient with neuropathic pain may have concomitant non-neuropathic pain and it should be consider that NP may be the first manifestation of a systemic disease.
A wide variety of abnormalities can cause NP,
i.e.,
metabolic disease,
infection,
ischemia,
injury,
entrapment,
connective tissue disease,
acquired immunodeficiency,
malignancy,
drugs,
and toxins.
Although NP may develop without any identifiable cause (intercostal neuralgia,
idiopathic polyneuropathy,
etc).
We can classify neuropathic pain syndromes in mononeuropathies (post-traumatic neuroma,
nerve or radicular compression and idiopathic causes),
polyneuropathies (ischemic,
metabolic),
deafferentation (postherpetic neuralgia,
amputation neuromas and phantom limb syndrome) and Complex Regional Pain Syndrome.
Central nervous system diseases includes thalamic stroke,
Wernicke's encephalopathy,
multiple sclerosis,
HIV encephalopathy and granulomatous diseases.
