Clinical Trial Summary

This study evaluates the brain correlates of Cognitive Training and Aerobic Exercise in schizophrenia. A third of participants will receive Cognitive Training plus Standard Care for schizophrenia. Another third of participants will receive Aerobic Exercise Training plus Standard Care for schizophrenia. A control group will of participants will receive Standard Care plus Occupational Activities for the same duration and frequency as the experimental groups.

Description:

This study, randomized, open, controlled with schizophrenia-standard-care, is aimed to determine structural and functional brain changes associated to cognitive remediation and physical exercise in schizophrenia.

The study participants will be enrolled in the catchment area of the Hospital Psiquiatrico de Alava, in the province of Alava, Basque Region, Northern Spain.147 patients diagnosed with schizophrenia will be randomly assigned to Cognitive Training Group or Aerobic Exercise Group or a Control Group for a five-month period.

Both Cognitive Training Group patients and Aerobic Exercise Group patients will participate in training sessions of 60 min/d, 3 d/wk. Patients assigned to Control Group will receive the standard care for schizophrenia in this area plus occupational activities for the same duration and frequency than the two experimental groups.

Cognitive Training will be implemented through REHACOP, a cognitive remediation program for Spanish speaking patients with schizophrenia whose efficacy on cognitive performance and negative symptoms has already been demonstrated in patients with schizophrenia. REHACOP is a "paper & pencil" based cognitive remediation program that covers 8 cognitive domains including social cognition. It is based on the principles of Optimization, Restauration & Compensation.

Aerobic Exercise Training will consist of an intensive physical exercise program supervised by certified graduates and doctorate students of Physical Activity and Sport Sciences. Sessions will include 10-minute warming-up and 10-minute back exercises and stretches. The main part of the session will consist of aerobic exercise (20-minute indoor bicycle) and muscle-resistance and strength exercises for 20 minutes. The intensity of the sessions will be determined on a case by case basis according to the HR necessary to achieve the intensity ranges (R2-moderate and R3-high). During the sessions, the bicycle's power and pace will be individually adjusted to achieve the selected HR.

The assessment batteries, neuroimaging and Serum BDNF levels will be administered and determined at baseline and immediately following the completion of the Cognitive Remediation or Aerobic Exercise interventions.

Primary outcomes: Structural and functional brain changes will be assessed by MRI neuroimaging. A Philips Achieva 3.0T MRI system equipped with a modular 32-channel architecture. 3 different types of images will be acquired: a) T1-weighted MRI imaging, b) Diffusion Tensor imaging, c) fMRI imaging at rest and using a cognitive paradigm.

Secondary outcomes will be changes in cognitive performance, clinical and functional changes and Serum BDNF changes.

Secondary	Clinical Symptoms of Schizophrenia measured by the Positive and Negative Symptoms Scale (PANSS).	Severity of the negative symptoms will be assessed with the total score of the Subscale for Negative Symptoms of the PANSS scale, which comprises 7 items, each one measuring a specific negative symptom. Each item ranges from 1 (absence of the symptom) to 7 (extreme severity of the symptom). Total score of the Negative Subscale of the PANSS ranges from 7 (minimum score) to 49 (maximum severity). Severity of positive symptoms will be assessed with the total score of the Subscale for Positive Symptoms of the PANSS, which comprises 7 items ranging from 1 (absence of the symptom) to 7 (extreme severity of the symptom). Total score of the Positive Subscale ranges from 7 (minimun score) to 49 (maximun severity). General Psychopathology will be assessed with the total score of the General Psychopathology Subscale which comprises 16 items ranging from 1(absence of the symptom) to 7 (extreme severity of the symptom).	5 months.
Secondary	Negative Symptoms of Schizophrenia measured by the Brief Negative Symptoms Scale (BNSS).	Severity of negative symptoms will be assessed with the total score of the BNSS. Values ranges from 0 (total absence of negative symptoms) to 90 (maximum severity of negative symptoms).	5 months
Secondary	Negative Symptoms of Schizophrenia measured by the Clinical Assessment Interview for Negative Symptoms Scale (CAINS)	Severity of negative symptoms will be assessed with the total score of the CAINS scale. Values ranges from 0 (total absence of negative symptoms) to 52 (maximum severity of negative symptoms).	5 months
Secondary	Functional Outcome measured by the UCSD Performance Based Assessment of Functional Skills in Severe Mental Illness (UPSA).	The UPSA includes the following 5 subscales: Financial Skills, Communication, Comprehension/Planning, Transportation, Household Management. Total scores for each subscale are calculated by transforming raw scores into a 0- to-10 scale, yielding comparable scores on each scale. In order to have a 100-point summary score, each subscale score is multiplied by 2, yielding subscale scores ranging from 1 to 20. A summary UPSA score is calculated by summing these five scores, resulting in total scores ranging from 0 to 100. Scores of 0 represent maximum severity of functional impairment and a score of 100 represents total absence of functional disability.	5 months
Secondary	Functional Outcome measured by the World Health Organization Disability Assessment Schedule (WHODAS 2.0).	The 36-item version of WHODAS 2.0 allows users to generate scores for the six domains of functioning and to calculate an overall functioning score. The scores assigned to each of the items - "none" (1), "mild" (2) "moderate" (3), "se- vere" (4) and "extreme" (5) - are summed. A score of 36 represents total absence of disability and 180 maximum severity of disability.	5 months
Secondary	Functional Outcome measured by the Short Form (36) Health Survey (SF-36).	The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.	5 months
