Impact of paroxysmal sympathetic hyperactivity on nutrition management after brain injury: A case series

Abstract

Objective: To review the nutritional requirements of all new inpatient brain injury admissions presenting with Paroxysmal Sympathetic Hyperactivity (PSH) in the rehabilitation setting.

Methods: RABIU is a 25-bed Regional facility in Northern Ireland which opened in 2006. All records of patients with a single episode non-progressive acquired brain injury admitted to RABIU from 2006 until the present were reviewed for evidence of PSH. Dietetic assessment and management was examined and recorded.

Results: Four patients with persisting paroxysmal sympathetic hyperactivity were identified. All patients displayed dystonia and posturing and had clinically important percentage weight loss. All had nutrition and/or hydration requirements markedly above their estimated requirement for slow weight gain, despite adjustment for brain injury. All four had posture-related complications of their dystonia and nutrition.

Conclusion: Careful monitoring of nutrition, hydration and mineral supplementation is paramount in patients presenting with paroxysmal sympathetic hyperactivity after brain injury. It is argued that morbidity may be reduced by aggressive and expert nutrition management.
