Origin: [F. paroxysme, Gr. , fr. to sharpen, irritate; para` beside, beyond + to sharpen, from sharp.]
Paroxysmal attacks or paroxysms are a sudden recurrence or intensification of symptoms, such as a spasm or seizure. These short, frequent and stereotyped symptoms can be observed in various clinical conditions. They are usually associated with multiple sclerosis or 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, paroxysmal nocturnal hemoglobinuria. It has also been noted as a symptom of gratification disorder in children. Paroxysmal attacks in various disorders have been reported extensively and ephaptic coupling 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. Most reported paroxysmal attacks are painful tonic spasms, dysarthria and ataxia, numbness and hemiparesis.
