Kindled non-convulsive behavioral seizures, analogous to primates. A 24th case of ‘limbic psychotic trigger reaction’: Bizarre parental infanticide —might nonvoluntariness during LPTR become objectified by primate model?

Abstract

Limbic psychotic trigger reaction (LPTR) includes paroxysmal, out-of-character, motiveless, unplanned felonies (or similarly bizarre social misbehavior), all committed during flat affect, autonomic arousal and a fleeting de novo psychosis. A transient limbic hyperactivation is implicated that impairs prefrontal monitoring (judgment, planning, intent, volition, emotional participation) but preserves memory for the acts. It is hypothesized that LPTR implicates an atavistic regression to a limbic 'paleo-consciousness', exemplified by a 24th patient (parental infanticide), presented herein. He had closed head injury and borderline abnormal posterior brain pathology (EEG/CT), which might have contributed to his unusually numerous visual hallucinations.

Recurrent schizophrenia-like psychosis as first manifestation of epilepsy: a diagnostic challenge in neuropsychiatry

“…In addition, neither the EEG recordings nor the clinical presentations in patients A and B met the criteria as proposed for this condition 17. A limbic psychotic trigger reaction (LPTR), as hypothesized by Pontius et al is also very unlikely because both patients showed disorientation during the act and amnesia for the act, in the absence of the typical out of character, bizarre, unplanned involuntary behaviors that are associated with LPTR 19,20…”
