Impact of severity of drug use on discrete emotions recognition in polysubstance abusers

Resting-state Abnormalities in Heroin-dependent Individuals

“…The most consistent finding was the abnormal recognition of negative emotions that is independent of abstinence length (Fernández-Serrano et al, 2010).Abstinent PSA showed poorer facial recognition of anger, fear and disgust and sadness, despite the length of abstinence but no significant difference was found in recognition of neutral or positive emotions, including surprise and happiness, relative to the control group (Fernández-Serrano et al, 2010). The duration of cocaine use was positively correlated to poorer processing of fear and anger, whereas the severity of cocaine use could predict weaker anger recognition (Fernández-Serrano et al, 2010). On the contrary, Woicik et al (2009) reported no abnormal emotional processing in cocaine abusers, compared to the healthy group.…”

“…Emotion recognition is essential to social readjustment and interaction (Blair, 2003;Fernández-Serrano et al, 2010). However, neural substrates that are responsible for emotion recognition are also involved in drug addiction(Verdejo-García and Bechara, 2009)and thus they were found to be impaired (Rosselli and Ardila, 1996;Reay et al, 2006;Homer et al, 2008).To the best of our knoweledge, the relationship between heroin addiction and emotion recognition has not been studied, but a lot of work has been conducted on other illicit drugs such as alcohol (Frigerio et al, 2002), polysubstance abuse (Foisy et al, 2005;Fernández-Serrano et al, 2010), opiates (Kornreich et al, 2003), cocaine (Kemmis et al, 2007) and psychostimulants (Verdejo-García et al, 2007a).…”

“…In other words, a network member observing the substance use by the other members has the tendency to mimic the friends' behavior (Reifman et al, 2006;Bohnert et al, 2009) Emotion recognition is essential to social readjustment and interaction (Blair, 2003;Fernández-Serrano et al, 2010).

Alterações na percepção emocional em usuários de cannabis

“…O consumo médio apresentado pelos usuários (crônicos e abstinentes) era de 2 aRevista da Biologia (2014) 13(1) ib.usp.br/revista mental. Usuários de cannabis requerem maior tempo para a identificação de emoções em faces (Platt et al, 2010), sem, no entanto, exibirem alterações quanto a acurácia durante a observação de imagens estáticas (Fernández-Serrano et al, 2010;Platt et al, 2010) e dinâmicas (Platt et al, 2010). A dessensibilização a estímulos estressores encontrada por Somaini et al, 2011, é uma forte evidência de que as alterações cognitivas podem sim ser observadas a nível comportamental.…”
