Brief Summary

Schizophrenia is heterogeneous and often disabling a disease that affects 1% of the population. Current psychopharmacological treatment significantly eliminates the presence of positive symptoms (especially delusions and hallucinations) and partly also negative symptoms (social withdrawal or abulia). In contrast, the cognitive deficits associated both with schizophrenia and depression are only limitedly influenced by pharmacological treatment.The cognitive impairment represents an important part of schizophrenia symptomatology and it has a severe negative impact on patients' quality of life. In depression is the impairment milder but still significantly contributes to patients' daily functioning. The profound deficit was repeatedly documented in the area of declarative and working memory. In this study, we study the effectiveness of virtual environment rehabilitation program focused on declarative memory, working memory and attention in comparison to standard paper-pencil rehabilitation led by an occupational therapist.

Interventions

The participants attended 10-15 computer sessions during 6-12 weeks. Each session lasted 30 minutes and consisted of the set of virtual environment tasks (Shooting Range,Virtual Supermarket Shopping Task and Objects). Shooting range demands differentiation of targets from non-targets and focuses on training of selective attention, psychomotor speed and inhibition control. Virtual Supermarket Shopping requires memorizing the shopping list and searching for products in the supermarket area. Objects requires memorizing of the spatial and temporal context while searching for objects.

Paper-pencil rehabilitation - Virtual environment rehabilitationVirtual environment rehabilitation - Paper-pencil rehabilitation

The participants in the paper-pencil rehabilitation attended 10-15 paper pencil sessions for 6-12 weeks. Each session lasted 45 minutes. Each paper-pencil session starts with a warm-up game. The session continues with a set of paper-pencil tasks focused on attention, fine motor skills, recall, short-term and long-term memory, verbal fluency, visual search, cognitive flexibility, abstraction and executive functions, numerical abilities. The tasks are adapted according to the participant´s abilities.
