Abstract
Patients suffering from schizophrenia often experience cognitive disturbances. Cognitive rehabilitation-computerized or non-computerized-is widely known as an alternative way to enhance cognitive functioning in patients with schizophrenia. The aim of the present review was to examine the role of cognitive rehabilitation (both computerized and non-computerized) for the alleviation of cognitive impairment in schizophrenia patients. Fourteen relative studies were examined and included in the present review. The results revealed that both computerized and non-computerized cognitive rehabilitation could enhance cognitive functioning and more specifically memory, attention, executive functioning, processing speed and in a few cases, even non-cognitive impairments, such as other schizophrenia symptoms. The present results support the efficacy of cognitive rehabilitation in schizophrenia patients, regardless of whether it is computerized or non-computerized. As the randomized control trials (RCTs) are limited in number, there is urgent need for more RCTs and longitudinal studies combining different kinds of interventions, as well as systematic reviews and meta-analyses, in order to further investigate and confirm the current results.
