Can an iPad app lift mood and sharpen mind after stroke?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * first-time stroke that occurred 6 months or more prior to study initiation * executive dysfunction as defined by a score of less than 1 standard deviation below age-adjusted normative score on at least one test of executive function in the screening assessment * diagnosis of Major Depressive Episode assessed by the Structured Clinical Interview for the DSM-5 (SCID). * at least moderate depressive symptoms as defined by Montgomery Asberg Depression Rating Scale ≥ 18 * motor function sufficient to operate an iPad and use a pen, based on self-report and observation * if treated with an antidepressant medication, must be on a stable dose for a minimum of 8 weeks at the time of study enrollment. * able to adhere to all testing and study requirements and willingness to participate in the full study duration Exclusion Criteria: * receptive aphasia as determined by a score of 2 or 3 on the NIH Stroke Scale \[NIHSS\] item 9 ("Best Language") * dysarthria that makes speech unintelligible (score of 2 on NIHSS item #10) * severe visual impairment or hemispatial neglect (score of 3 on NIHSS item #3 or score of 2 on NIHSS item #11) * patient already enrolled in ongoing concurrent cognitive rehabilitation (note that if a subject is already enrolled in psychotherapy, this will not be grounds for exclusion) * non-fluency in English * presence of or history of significant neurologic or neurodegenerative disorder other than stroke * presence of dementia based on dependence in basic ADLs due to cognitive deficits * history of psychosis or mania (evaluated using the SCID). * active suicide ideation (assessed via the Columbia Suicide Severity Rating Scale) * severe executive dysfunction (based on clinical judgment during screening evaluation) precluding use of the iPad * severe depression-even in the absence of active suicidal ideation-based on the screening evaluation and clinical judgment of the PI, which warrants a higher level of care and/or immediate referral to psychiatric services. * pregnancy * any other clinical or medical reason in the PI's initial screening evaluation that suggests the study is not appropriate for the participant.
