Dystonic storm: a practical clinical and video review

Abstract: Dystonic storm is a frightening hyperkinetic movement disorder emergency. Marked, rapid exacerbation of dystonia requires prompt intervention and admission to the intensive care unit. Clinical features of dystonic storm include fever, tachycardia, tachypnea, hypertension, sweating and autonomic instability, often progressing to bulbar dysfunction with dysarthria, dysphagia and respiratory failure. It is critical to recognize early and differentiate dystonic storm from other hyperkinetic movement disorder emerg… Show more

“…So far, no study has specifically addressed the pathophysiology of SD. It has been postulated that in patients with underlying dystonia, increased spasms severity may result from an increased pallidal output . A recent review has highlighted the similarities between epilepsy and paroxysmal dyskinesias, including their episodic nature, triggering factors, and the therapeutic response to the same drugs .…”

“…Overall, neurosurgery is the most successful strategy (effective in 33.7% of episodes) . The most recent proposed treatment algorithm suggested a management that divides decision making into the following 2 periods: the first 24 hours, when supportive therapy should be initiated and appropriate patients should be identified early as candidates for pallidal DBS or IBT, and the subsequent 2 to 4 weeks, when the aim is the symptomatic control of dystonia and supportive therapies …”

“…This study shows that SD is a lifetime threat. 6,9,10 The spectrum of disorders that produce SD is large. Frequently associated neurological signs and significant morphological alterations support the concept of network-level impairment, including cortical involvement, 11 and explain the complexity of dystonic conditions and the risk of progression into SD.…”

“…The limited therapeutic efficacy of anti‐dystonia drugs and the potential risk of mortality necessitate immediate implementation of emergency procedures for status dystonicus . Although the reported cases of status dystonicus are limited, the efficacy of early, aggressive treatment with pallidal DBS has been suggested .…”
