Objective: Paroxysmal sympathetic hyperactivity (PSH) can occur in up to 10% of severe traumatic brain injury (TBI) patients and is associated with poorer outcomes. A consensus regarding management is lacking. We provide a practical guide on the multi-faceted clinical management of PSH, including pharmacological, procedural and non-pharmacological interventions. In addition to utilizing a standardized assessment tool, the use of medications to manage sympathetic and musculoskeletal manifestations (including pain) is highlighted. Recent studies investigating new approaches to clinical management are included in this review of pharmacologic treatment options.
Conclusion: While studies regarding pharmacologic selection for PSH are limited, this paper suggests a clinical approach to interventions based on predominant symptom presentation (sympathetic hyperactivity, pain and/or muscle hypertonicity) and relevant medication side effects.

This systematic review and meta-analysis was conducted to identify a 'normative' sympathetic response to isometric handgrip and post-exercise circulatory occlusion. Structured searches of databases were performed until June 2024. We included all primary studies (other than systematic reviews and meta-analyses), and inclusion criteria were: population (all populations); intervention (isometric handgrip and post-exercise circulatory occlusion); comparator (baseline); and outcome (MSNA).

Purpose: To revisit the pharmacology and real-world use of carbidopa in the management of autonomic disorders.
Methods: To identify articles suitable for this review, a search of the PubMed database was conducted in January 2025 using the keywords "Carbidopa," "MK-486," and "L-alpha-methyldopa hydrazine."
Results: The pharmacotherapeutic role of carbidopa extends beyond the management of Parkinson's disease.
Electrophysiological Changes in Simulated Atrial Sheets Due to Sympathetic Hyperactivity.
Annu Int Conf IEEE Eng Med Biol Soc
July 2024
The electrophysiological changes in the atria due to sympathetic hyperactivity during episodes of psychological distress are unclear. We simulated sympathetic hyperactivity by rapidly pacing atrial sheets with increasing adrenergic stimulation (AS) spatial densities. We measured changes to the electrophysiological parameters of atrial sheets, such as captured waves (CW), conduction speed (CS), slope of depolarization (SoD), isolated conduction channels (ICC), and wavefront ratio (WFR), using videos and action potential signals.

Guillain-Barré syndrome (GBS) is an acute inflammatory peripheral nerve disorder mediated by autoimmune mechanisms. However, its co-occurrence with autoimmune encephalitis (AE) is rare. We present a 51-year-old man who initially presented with symmetrical numbness and weakness in all limbs, followed by hallucinations, behavioral abnormalities, and consciousness disturbances.

Paroxysmal sympathetic hyperexcitation (PSH) refers to a clinical syndrome characterized by a sudden increase in sympathetic excitability caused by severe brain injury. This study aims to investigate the effectiveness and practicality of combining transcranial direct current stimulation (tDCS) with medication to treat PSH and employ non-linear electroencephalography (EEG) to assess changes in cortical activation post-intervention. 40 PSH patients were randomly assigned to receive either active tDCS or sham tDCS treatment over an 8-week period.
