Young adults with psychotic-spectrum disorder have lower odds of attaining educational goals, partly due to cognitive problems. Cognitive remediation (CR) could improve cognitive- and potentially academic functioning. The current study examined an adapted CR-intervention ‘Mindset’ aimed at academic functioning for people with a psychotic-spectrum disorder in secondary education. Pilot-feasibility study of Mindset including the experience of nine participants with psychotic-spectrum disorder who received Mindset and six CR trainers. Post-CR interviews with participants and trainers were subjected to qualitative evaluation. Furthermore, preliminary results from pre- to post-CR changes on the College Self-Efficacy Inventory (CSEI), Cognitive Problems and Strategies Assessment (CPSA) and Multidimensional Students’ Life Satisfaction Scale (MSLSS) are presented using Reliable Change Index (RCI) and effect-sizes (Cohen’s d). Qualitative evaluation showed that overall experience with Mindset was positive for participants and trainers. Mindset was not experienced as too difficult and aligned well with education. However, tailoring to the individual is required. Effect sizes in change from pre- to post-CR were small for school satisfaction (d = 0.25) and self-reported cognitive problems (d = 0.12), small to medium for increases in self-efficacy (d = 0.49) and large for increases in strategy use (d = 3.58). Feasibility of Mindset was good in terms of adaptation and expansion, implementation and limited efficacy. However, concerning acceptability, drop-out prior to Mindset was high and Mindset needs adjustment in terms of individual tailoring and language. Future studies have to attest to its efficacy.

Most severe mental disorders have their onset between the age of 17 and 27, a time when many young adults begin participating in secondary or post-secondary education. The cognitive deficits typically associated with psychiatric disorders, especially psychotic disorders, increase the risk of leaving school early, which can lead to a reduction in employment opportunities later on in life and, in turn, a poorer long-term prognosis. Therefore, specific interventions aiming to improve these cognitive functions are needed. Cognitive remediation (CR) aims to improve cognitive functioning and may increase real-world functioning in educational performance. This study aims to examine the feasibility and applicability of a CR training named Mindset for students with psychotic disorders in the Netherlands.

BackgroundPhysical exercise in cancer patients is a promising intervention to improve cognition and increase brain volume, including hippocampal volume. We investigated whether a 6-month exercise intervention primarily impacts total hippocampal volume and additionally hippocampal subfield volumes, cortical thickness and grey matter volume in previously physically inactive breast cancer patients. Furthermore, we evaluated associations with verbal memory.MethodsChemotherapy-exposed breast cancer patients (stage I-III, 2–4 years post diagnosis) with cognitive problems were included and randomized in an exercise intervention (n = 70, age = 52.5 ± 9.0 years) or control group (n = 72, age = 53.2 ± 8.6 years). The intervention consisted of 2x1 hours/week of supervised aerobic and strength training and 2x1 hours/week Nordic or power walking. At baseline and at 6-month follow-up, volumetric brain measures were derived from 3D T1-weighted 3T magnetic resonance imaging scans, including hippocampal (subfield) volume (FreeSurfer), cortical thickness (CAT12), and grey matter volume (voxel-based morphometry CAT12). Physical fitness was measured with a cardiopulmonary exercise test. Memory functioning was measured with the Hopkins Verbal Learning Test-Revised (HVLT-R total recall) and Wordlist Learning of an online cognitive test battery, the Amsterdam Cognition Scan (ACS Wordlist Learning). An explorative analysis was conducted in highly fatigued patients (score of ≥ 39 on the symptom scale ‘fatigue’ of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire), as previous research in this dataset has shown that the intervention improved cognition only in these patients.ResultsMultiple regression analyses and voxel-based morphometry revealed no significant intervention effects on brain volume, although at baseline increased physical fitness was significantly related to larger brain volume (e.g., total hippocampal volume: R = 0.32, B = 21.7 mm3, 95 % CI = 3.0 – 40.4). Subgroup analyses showed an intervention effect in highly fatigued patients. Unexpectedly, these patients had significant reductions in hippocampal volume, compared to the control group (e.g., total hippocampal volume: B = −52.3 mm3, 95 % CI = −100.3 – −4.4)), which was related to improved memory functioning (HVLT-R total recall: B = −0.022, 95 % CI = −0.039 – −0.005; ACS Wordlist Learning: B = −0.039, 95 % CI = −0.062 – −0.015).ConclusionsNo exercise intervention effects were found on hippocampal volume, hippocampal subfield volumes, cortical thickness or grey matter volume for the entire intervention group. Contrary to what we expected, in highly fatigued patients a reduction in hippocampal volume was found after the intervention, which was related to improved memory functioning. These results suggest that physical fitness may benefit cognition in specific groups and stress the importance of further research into the biological basis of this finding.
