Neurostorming in Brain Injury
Characteristics of Neurostorming
- Neurostorming, also known as paroxysmal sympathetic hyperactivity (PSH), is characterized by episodes of tachycardia, hypertension, tachypnea, hyperthermia, diaphoresis, and posturing, according to Praxis Medical Insights 1
- Symptoms of neurostorming typically occur in a paroxysmal pattern with periods of relative normalcy between episodes, as noted by Praxis Medical Insights 2
- Episodes of neurostorming can be triggered by external stimuli such as repositioning, suctioning, or other care activities, as reported by Praxis Medical Insights 1
Brain Injury Patterns Associated with Neurostorming
- Hypoxic-ischemic brain injury can trigger neurostorming without diffuse axonal injury being present, as found in a study published in Circulation 3
- Symptomatic hypoxic-ischemic injury with diffuse brain cell death can present with global neurological signs, according to the Journal of the American College of Cardiology 4
- Focal traumatic lesions affecting autonomic centers or pathways can cause neurostorming, as noted by Praxis Medical Insights 2
Diagnostic Considerations
- Non-contrast CT is the first-line imaging modality in acute traumatic brain injury but has limitations in detecting both diffuse axonal injury and early signs of neurostorming, as stated by Praxis Medical Insights 1
- MRI is indicated when CT results are normal but persistent unexplained neurologic findings are present, according to Praxis Medical Insights 1, 2
Management Implications
- Management of neurostorming focuses on symptom control regardless of underlying etiology, as recommended by Praxis Medical Insights 2
- Treatment strategies for neurostorming include maintaining adequate cerebral perfusion with systolic BP >110 mmHg, as suggested by Praxis Medical Insights 2
- Controlling ventilation through intubation and mechanical ventilation when necessary is a treatment strategy for neurostorming, as noted by Praxis Medical Insights 2
- Preventing secondary brain injury through avoidance of hypocapnia is a key aspect of neurostorming management, according to Praxis Medical Insights 2
- Early physical therapy to prevent contractures is a recommended treatment strategy for neurostorming, as stated by Praxis Medical Insights 2
