Neuropathological Changes in the Brains of Suicide Killers

Background: Homicide combined with subsequent suicide of the perpetrator is a particular form of interpersonal violence and, at the same time, a manifestation of extreme aggression directed against oneself. Despite the relatively well-described individual acts of homicide and suicide, both in terms...

Results: The results of our research indicate the presence of neurodegenerative changes including multiple deposits of ß-amyloid in the form of senile/amyloid plaques and perivascular diffuse plaques. Conclusions: Neurodegenerative changes found in the analyzed brains of suicide killers may provide an interesting starting point for a number of analyses. The presence of neurodegenerative changes at such a young age in some murderers may suggest preclinical lesions that affect cognitive functions and are associated with depressed moods.Tomasz StępieńJanusz HeitzmanTeresa Wierzba-BobrowiczPaweł GosekPaweł KrajewskiAgnieszka Chrzczonowicz-StępieńJarosław BerentTomasz JurekFilip BolechałaMDPI AGarticlehomicidesuicidemurderer’s brainmurder–suicideextended suicideneuropathological changesMicrobiologyQR1-502ENBiomolecules, Vol 11, Iss 1674, p 1674 (2021)
