Acute agitated delirious state associated with Taser exposure.

Area of Science:

• Emergency Medicine
• Neuroscience
• Forensic Science

Background:

• Taser devices are widely used as nonlethal force, often presumed to have a favorable safety profile.
• However, associations between Taser use and in-custody mortality, particularly in agitated individuals, remain a concern.
• The mechanisms underlying these associations, and the potential for Taser exposure to induce agitation, are not well understood.

Observation:

• A case report details a 37-year-old male with no prior psychiatric history who experienced multiple Taser exposures during an arrest.
• Following exposure, the individual developed acute agitation and delirium in the emergency department, necessitating sedation and intubation.
• Medical evaluations, including toxicology, imaging, and psychiatric assessments, did not reveal alternative causes for the observed state.

Findings:

• The patient exhibited a prolonged state of refractory delirium lasting three days post-Taser exposure.
• Toxicology results showed therapeutic methadone levels and trace marijuana, deemed insufficient to explain the acute behavioral changes.
• The absence of pre-existing psychiatric conditions or significant substance abuse in the patient strengthens the potential association with Taser use.

Implications:

• This case is the first to report a temporal association between Taser exposure and the onset of acute agitation and delirium in an otherwise non-agitated individual.
• The findings suggest that Taser devices, despite their intended use, may paradoxically precipitate agitated or delirious states.
• Further research is crucial to elucidate the neurophysiological effects of Taser exposure and its potential to induce psychiatric emergencies.
