Central pain syndrome, also known as central neuropathic pain, [1] is a neurological condition consisting of constant moderate to severe pain due to damage to the central nervous system (CNS) which causes a sensitization of the pain system. [2] [3] The extent of pain and the areas affected are related to the cause of the injury. [4]
Neuropathic pain is pain caused by a lesion or disease of the somatosensory nervous system. [2] [3] Neuropathic pain may be associated with abnormal sensations called dysesthesia or pain from normally non-painful stimuli . It may have continuous and/or episodic components. The latter resemble stabbings or electric shocks.
Signs and symptoms of neuropathic pain include allodynia (pain caused by non-painful stimuli), hyperalgesia (an increase in pain perception due to painful stimuli), and paresthesia (abnormal sensations such as needle bites, tingling, itching, and decreased or loss of sensitivity).
Nociplastic pain, also known as central sensitisation, is a third category of pain that is mechanistically distinct from nociceptive pain, which is due to inflammation and tissue damage. As well as neuropathic pain, which is caused by nerve damage. [5] It may occur in combination with the other types of pain or in isolation.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Dysesthesia, along with polyneuropathy can be a symptom of nerve damage caused by Lyme disease. [4] The dysesthetic sensations continue after the successful antibiotic treatment of Lyme disease. Dysesthesia is a common symptom of a withdrawal from alcohol or other drugs. Dysesthesia is also a common symptom of multiple sclerosis. It is an ...
They have significant efficacy in treatment of peripheral and central neuropathic pain. Treatments last 4–12 hours and in general are well tolerated, and the occurrence of adverse events does not differ significantly across patients. Commonly reported side-effects are dizziness, decreased intellectual performance, somnolence, and nausea. [1]
Lasers can emit a radiant-heat pulse stimulus to selectively activate A-delta and C free nerve endings. LEP abnormalities may be indicative of neuropathic pain, while a normal LEP is often more ambiguous. LEPs can assess damage to both central and peripheral nervous systems. [6]
