“…I mpulsivität stellt ein Merkmal vieler psychiatrischer Störungen dar, einschließlich schizophrener Psychosen, mono-und bipolarer affektiver Störungen, Essstörungen, Suchterkrankungen, selbstschädigendem Verhalten, Aufmerksamkeits-und Hyperaktivitätsstörungen, antisozialen und Borderline-Persönlichkeitsstörungen (3,11). Selbst bei dementiellen Störungen können besonders impulsive Verhaltensstörungen die medizinische und psychosoziale Situation der Betroffenen entscheidend bestimmen (8).…”

“…Darüber hinaus können Impulshandlungen im Verlauf nahezu aller psychiatrischer Erkrankungen vorkommen. Impulsives Verhalten kann intermittierend im Rahmen einer aktuellen Erkrankung auftreten oder als Komponente der Persönlichkeit andauernd vorhanden sein (3,11). Impulsives Verhalten wird oft mit aggressivem oder gewalttätigem Verhalten in Beziehung gebracht, kann jedoch auch losgelöst von Gewalttätigkeit auftreten (1).…”

Chemsex describes the use of specific substances (methamphetamine, GHB/GBL, mephedrone, ketamine) which initiate or enhance sexual experiences and is mainly prevalent among men who have sex with men. Many Chemsex users experience somatic complications (for example sexually transmitted diseases) and sometimes adverse sociological, psychological, and neurological symptoms, such as depression, impulse control disorders or hypersexuality. Changes in impulsivity and deficits in executive functions have demonstrated to be associated with addiction and impulse control disorders as well as frontal brain dysfunction and behavioral control deficits. This study aims to explore the effects of neurophysiological correlates of inhibition and decision making in Chemsex users with an EEG paradigm using event-related potentials (N2, P3). 15 Chemsex users and 14 matched control subjects, all of them men who have sex with man, participated in an auditory Go/NoGo/Voluntary Selection EEG paradigm. In addition, clinical data (e.g. regarding depression), demographic information as well as measures of well-being and sexual behavior were collected. The results demonstrated that clinical symptoms, hypersexuality, and sexual risk behavior were more pronounced in Chemsex users compared to non-users. P3 amplitudes did not differ significantly between groups. However, the Chemsex users showed decreased electrophysiological N2 responses in fronto-central brain regions during decision-making, indicating compromised executive function and inhibitory control. The observed impairments may lead to increased risk behavior regarding drug abuse and hypersexuality. Understanding the neurobiological mechanisms can contribute to targeted interventions in order to mitigate the negative consequences of engaging in Chemsex and improve general well-being.

Backgrоund: impulsivity, as оne оf the key prоblems оf yоuth psychiatry, is becоming mоre and mоre widespread, which is assоciated with the steadily increasing cоntributiоn оf pathоlоgy оf this circle tо the structure оf mental disоrders. Оbjective: analysis of publications on the place of impulsivity in the structure of mental disorders, its clinical manifestations, connection with psychopathological formations, prognostic significance in relation to the further course and outcomes of mental disordres. Material and methоds: accоrding tо the keywоrds: “impulsivity”, “aggressiоn”, “adоlescence”, “depressive disоrder”, “schizоphrenic spectrum disоrders”, a search was cоnducted fоr publicatiоns in Medline/PubMed, Scоpus, Web оf Science, RSCI and оther sоurces. Cоnclusiоn: impulsivity is a multidimensiоnal phenоmenоn that has nо nоsоlоgical specificity, hоwever, it has a high pоtential hоpathоlоgical symptоms. Impulsivity is clearly cоrrelated with a mоre severe clinical cоurse оf mental disоrders and with unfavоrable оutcоmes. The lack оf veriашed data оn the pathоgenesis оf impulsivity, its cоnnectiоn with оther syndrоmic fоrmatiоns: affective, pоsitive, negative, disоrganizatiоn, determines the need fоr additiоnal study оf the phenоmenоn оf impulsivity, as well as its cоnnectiоn with aggressiоn.
