Pontius syndromeJoe Segen2016-11-16T13:39:48+00:00
Definition A transient neuropsychiatric state in which a previously normal person, often a social loner, ‘snaps’ and commits unpremeditated and remorseless acts of extreme violence–e.g., homicide and mass murder
Clinical findings The episode may be preceded by hallucinations or déjà vu, and accompanied by nausea, tachycardia, incontinence, delusions of grandeur
The validity of this syndrome is uncertain, and attributed by Pontius to an engendering neurophysiologic trigger, which she believed ‘kindles’ a limbic seizure. There has been concern that validation of the syndrome might invite its misuse as a legal defense for what might be defined as irrational or motiveless murders; if proven valid, Pontius syndrome could be responsible for 1% of homicides committed each year in the US.
Synonyms Irrational murder, limbic psychotic trigger reaction, motiveless murder
