DOI: 10.1007/s00701-025-06566-9
Abstract: Overstimulation of the autonomic nervous system (ANS) in the acute phase after traumatic brain injury (TBI) may lead to paroxysmal sympathetic hyperactivity (PSH) syndrome. This study aimed to investigate the impact of the relationship between… read more here.

DOI: 10.1007/s12028-024-02149-1
Abstract: Severe traumatic brain injury (TBI) can lead to transient changes in autonomic nervous system (ANS) functioning and development of paroxysmal sympathetic hyperactivity (PSH) syndrome. Clinical manifestation of ANS disorders may be obscured by therapeutic interventions… read more here.

DOI: 10.1089/neu.2020.7597
Abstract: Paroxysmal sympathetic hyperactivity (PSH) occurs in ~10% of patients following acute severe brain injury. Whilst PSH is associated with worse outcomes there are no clinical practice guidelines to inform treatment. We aimed to systematically review… read more here.
