Abstract:
The article presents the results of pilot study implemented to determine cognitive disorders in patients taking "Spice". The purpose of research is to identify targets of psychological correction interventions to prevent cognitive deficiency in patients addicted to synthetic cannabinoids. The pilot sampling consisted of 30 patients taking "Spice". The control group consisted of 30 healthy individuals. Along with social consequences, one of the important focuses of the study was investigation of cognitive sphere of patients. A number of pathopsychologic tests was applied. The study established that patients demonstrated disorders of various functions of memory, attention, mental pace and thinking. In particular, disorders of short-term, long-term and mediate memory and mental tempo were revealed. Also, reduced activity of attention took place. The distortion and decreasing of generalization and poor prehension occurred reliably more often as compared with control group. The established cognitive disorders in patients taking "Spice" can be considered as targets for psychological correction interventions to prevent cognitive deficiency in patients addicted to synthetic cannabinoids.
