This current study assessed neurocognitive functioning in a carefully selected sample of schizophrenia patients with and without heavy cannabis use and healthy controls. All subjects were negative for any other substance use. Schizophrenia subjects had impaired neurocognitive functions across a wide range of tasks compared to healthy controls. Cannabis using schizophrenia patients had focused impairments on tasks of attention, and the findings suggest an impulsive pattern of response among these patients.
本研究评估了在精心挑选的伴有和不伴有重度大麻使用的精神分裂症患者样本以及健康对照组中的神经认知功能。所有受试者均未使用任何其他物质。与健康对照组相比，精神分裂症患者在广泛的任务中表现出神经认知功能受损。使用大麻的精神分裂症患者在注意力任务上表现出注意力集中障碍，研究结果表明这些患者存在冲动反应模式。
