Wikipedia Meaning and Definition on 'Paroxysm'
Paroxysmal attacks are short, frequent and stereotyped symptoms that can be observed in various clinical conditions. They are usually associated with multiple sclerosis, pertussis, but they may also be observed in other disorders such as encephalitis, head trauma, stroke, asthma, trigeminal neuralgia, breath-holding spells, epilepsy, malaria, tabes dorsalis, and Behçet's disease. It has also been noted as a symptom of Gratification disorder in children.
Paroxysmal attacks in various disorders have been reported extensively and ephaptic transmission of demyelinated nerves has been presumed as one of the underlying mechanisms of this phenomenon. This is supported by the presence of these attacks in multiple sclerosis and tabes dorsalis, which both involve demyelination of spinal cord neurons. Exercise, tactile stimuli, hot water, anxiety and neck flexion may provoke paroxysmal attacks. Mostly reported paroxysmal attacks are painful tonic spasms dysarthria and ataxia, numbness and hemiparesis. They are typically different from other transient symptoms by their brevity (lasting no more than 2 minutes), frequency (from 1-2 times/day up to a few hundred times/day), stereotyped fashion and excellent response to drugs (usually carbamazepine). Withdrawal of symptoms without any residual neurological finding is another key feature in their recognition.[See more about Paroxysm at Dictionary 3.0 Encyclopedia]
