Abstract

Purpose of Review

Dysautonomia, now known as paroxysmal sympathetic hyperactivity (PSH) is a phenomenon described by fever, hypertension, tachycardia, and diaphoresis among other symptoms affecting patients after traumatic brain injury. The goal of this review is to review the diagnosis, treatment, and outcomes of patients with PSH based on the most current literature.

Recent Findings

Most recently, PSH has been better defined with a specific scoring system that can be applied in the clinical setting. Treatment of PSH is still quite clinically variable.

Summary

PSH has been described for decades, but has only achieved consensus definition. Treatment remains variable institutionally. Much further investigation is needed to systematically assess the multiple currently utilized treatment modalities, and their effect on long-term outcomes based on the current defining criteria.
