2022年7月6日 · Paroxysmal sympathetic hyperactivity (PSH) is a pattern of recurrent bursts of dysregulated sympathetic activity, resulting from severe brain injury. These episodes of sympathetic activation are short, dramatic, and often triggered by stimulation.

Currently, the Paroxysmal Sympathetic Hyperactivity-Assessment Measure (PSH-AM) scale consists of two separate constructs: (1) the clinical feature scale (CFS), to identify the intensity of cardinal features, and (2) the diagnosis likelihood tool (DLT), to evaluate the likelihood of the presence of PSH, and is by far the best diagnosis tool for ...

PSH is defined as a clinical syndrome manifested by paroxysmal episodes of sympathetic activity that occur in patients with severe acute brain injury [5]. Core clinical features include tachycardia, hypertension, tachypnea, hyperthermia, sweating, and/or increased muscle tone with possible dystonic posturing.

Diagnosis of PSH is made using the paroxysmal sympathetic hyperactivity-assessment measure (PSH-AM) score, which comprises “clinical features severity” (CFS) score and “diagnosis likelihood tool” (DLT) score. A 35-year-old woman diagnosed to have echo-proven chronic rheumatic heart disease for 25 years.

A consensus set of diagnostic criteria named PSH-Assessment Measure (PSH-AM) has been developed recently, which is consisted of two components: a diagnosis likelihood tool derived from clinical characteristics of PSH, and a clinical feature scale assigned to the severity of each sympathetic hyperactivity.

Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system. Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis, and hyperthermia. [1] .

2018年3月8日 · Identifying factors that risk-stratify patients with primary brain injury for PSH is important for early and appropriate diagnosis and treatment. PSH has a varying incidence of 8–33% after acute brain injury. It occurs primarily after TBI (79.4%), hypoxic brain injury (9.7%), and stroke (5.4%) [4].
