Abstract
A coexistência de perturbações psiquiátricas com abuso / dependência de
substâncias ilícitas é um problema de saúde pública global. Devido a escassez de
estudos acerca do Perfil Neuropsicológico em toxicodependentes, este estudo centra-se
na investigação de uma das perturbações psiquiátricas mais devastadoras e
incapacitantes da atualidade na patologia dual, a esquizofrenia. Estima-se que 75 a 85%
dos doentes com esta patologia mental apresentem alterações das funções cognitivas.
O objetivo primordial deste estudo é descrever o Perfil Neuropsicológico de
indivíduos com esquizofrenia e dependentes de substâncias e simultaneamente
comparar as diferenças no funcionamento cognitivo entre indivíduos policonsumidores
com diagnóstico de esquizofrenia com indivíduos policonsumidores sem diagnóstico de
patologia psiquiátrica. A amostra foi formada por 40 participantes, divididos em dois
grupos: um grupo com 20 indivíduos do sexo masculino policonsumidores com
diagnóstico de esquizofrenia e um grupo com 20 indivíduos do sexo masculino
policonsumidores sem diagnóstico de patologia psiquiátrica.
Os resultados demonstraram que os indivíduos com esquizofrenia e com
policonsumos apresentam défices cognitivos estatisticamente significativos em várias
funções cognitivas (atenção concentrada e velocidade de processamento, inibição de
respostas automáticas, flexibilidade mental, memória de trabalho, capacidade de
planificação e estratégia de ação e capacidade visuoconstrutiva) comparativamente aos
indivíduos sem diagnóstico de patologia psiquiátrica e com policonsumos. Conclui-se,
então que indivíduos com patologia dual são mais vulneráveis aos efeitos tóxicos das
substâncias ilícitas.
The coexistence of psychiatric disorders with abuse / dependence on illicit substances is a global public health problem. Due to the lack of studies about the Neuropsychological Profile in drug addicts, this study focuses on the investigation of one of the most devastating and disabling psychiatric disorders of the present day in the dual pathology, schizophrenia. It is estimated that 75 to 85% of patients with this mental disorder show evidences of altered cognitive functions. The main objective of this study is to describe the Neuropsychological Profile of individuals with schizophrenia and dependence substance and also compare the differences in cognitive functioning between diagnosed with polydrug user with individuals without a diagnosis of psychiatric pathology. The sample consisted of 40 participants, divided into two groups: a group of 20 male polydrug user individuals diagnosed with schizophrenia and one group with 20 male polydrug user individuals without a diagnosis of psychiatric pathology. The results revealed that individuals with schizophrenia and polydrug show statistically significant cognitive deficits in various cognitive functions (concentrated attention, speed processing, inhibition of automatic responses, mental flexibility, working memory, planning capacity and action strategy and visuoconstructive capacity) compared to individuals without a diagnosis of psychiatric disorder and polydrug. We also conclude that individuals with dual pathology are more vulnerable to the toxic effects of substances.
