Clinical characteristics, diagnostic challenges, and outcome of paroxysmal sympathetic hyperactivity in pediatric patients: a retrospective cohort study in a tertiary hospital setting

PSH in pediatric patients predominantly arises from non-traumatic brain injuries, presenting with nonspecific symptoms that often lead to misdiagnosis. This study underscores the importance of early and accurate diagnosis in improving patient outcomes. Clonidine shows potential as a life-saving intervention in this context. These findings highlight the need for further research to refine diagnostic criteria and optimize treatment strategies for pediatric PSH.
