The aim of the study was to evaluate the level of cognitive and social functioning in two groups of schizophrenia patients using clinical tools, psychological tests, QEEG, and changes in the brain-derived neurotrophic factor (BDNF) activity in subjects’ serum.

Randomly selected men diagnosed with schizophrenia were enrolled in the study and divided into two groups. Gr. 1 was formed by patients who did not undergo a structured rehabilitation program, while Gr. 2 was formed by patients undergoing standard rehabilitation, as provided in theprogramof the Psychiatric Rehabilitation Unit. Both groups underwent a comparative analysis of demographic parameters and based on: PANSS, AIS, GSES, and BCIS, psychological tests CTT-1, CTT-2, d2, QEEG, and changes in blood BDNF levels. To assess the effect of rehabilitation, the results obtained in both groups were compared after 12 weeks and their analysis was performed in accordance with assumptions for the experimental project. The study presents research hypotheses and pre-test and post-test comparisons of the groups, on the basis of selected research tools.

The data obtained in measurement 1 indicate that both groups did not differ significantly in terms of: age, education, place of residence, treatment at outpatient facilities, medicines taken, and suicide attempts. Differences concerned: marital status, children, number of hospitalizations, and employment status. Furthermore, no significant differences were found for the studied groups concerning: serum levels of the brain-derived neurotrophic factor, values obtained on the PANSS, AIS, and GSES, and alpha/theta, theta/beta and theta/SMR ratios. The analyses performed in measurement 2 indicate that structured rehabilitation influences reduce negative symptoms, cause an increase in BDNF levels, cause an improvement in cognitive and social functioning and positively influence the perception speed and accuracy.

The positive effect of structured rehabilitation influences allows to say that rehabilitation represents a necessary part of the comprehensive psychiatric treatment and should already be implemented during the first episode of the illness.
