A disorder in counterfactual thinking (CFT), a behavioural executive process linked to the prefrontal cortex functioning, has not been investigated in TS. CFT refers to the generation of a mental simulation of alternatives to past factual events, actions, and outcomes. It is a pervasive cognitive feature in everyday life and it is closely related to decision-making, planning, problem-solving, and experience-driven learning—cognitive processes that involve wide neuronal networks in which prefrontal lobes play a fundamental role. Clinical observations in patients with focal prefrontal lobe damage or with neurological and psychiatric diseases related to fr...

The cognitive domains affected are in particular executive functions. These comprise planning, organising, conducting, assessing and controlling actions. Dual task abilities, that is the ability to perform successive or simultaneous tasks, are not easy to be evaluated and recovered by traditional paper and pencil methods, due to their ecological and contextual nature. NeuroVR 1.5 is a cost-free virtual reality platform based on open-source software, allowing professionals to easily modify a virtual world, to best suit the needs of the clinical setting.The present study was designed to develop and test a NeuroVR based tool for the rehabilitation of shifting of attention and action planning functions using tasks reminiscent of daily life tasks. We present the virtual environment and the cognitive procedure we developed, discussing two stroke pa...
