Level 5 - mechanism / opinion, no new human data
Narrative review and mechanism-based hypothesis without systematic methodology or primary trial data.
PubMed 27790150 · doi:10.3389/fphys.2016.00435
What was done
Narrative review synthesizing the clinical history, symptomatology, and postmortem neurochemical findings associated with excited delirium syndrome, psychostimulant intoxication, and acute exhaustive mania.
What was found
The abstract reports no numerical data, sample sizes, or effect estimates. Qualitatively, it states that excited delirium shares behavioral features with Bell's mania and is linked to psychostimulant abuse. It notes that postmortem brain examinations demonstrate loss of dopamine transporter regulation and increased heat shock protein 70 expression.
Why it matters
The review outlines a biological framework proposing that central dopamine dysregulation and hyperthermia directly drive autonomic failure and sudden death in agitated individuals.
Limits
This is a non-systematic narrative review providing no quantitative data, primary experimental controls, or systematic search criteria. The proposed causal mechanisms rely on mechanistic inferences without prospective human validation.
