improving cognitive health in covid-19 survivors

Conditions: Cognitive Dysfunction; Covid19

Summary: the primary objective of this study is to investigate the efficacy of akl-t01, a remotely-delivered digital cognitive intervention, relative to a waitlist control in improving cognitive functioning in covid-19 survivors.

emerging evidence suggests a subgroup of survivors of covid- 19 have residual difficulties with cognition and daily functioning. these deficits are pronounced in cognitive domains including attention, learning and executive skills, and may continue to impact quality of life after recovery from other covid-19 symptoms. this study aims to investigate the efficacy of akl-t01 (akili interactive), a remotely-delivered digital cognitive intervention, in targeting and improving cognition and functional outcomes in individuals recovering from covid-19. the efficacy of the akl-t01 intervention will be measured relative to a waitlist control group.

Eligibility criteria:
inclusion criteria: * male or female 18-89 years of age * documentation of a deficit in cognitive function (score \> 1 standard deviation below normal range) compared to age-adjusted normative data) on at least one screening measure of attention and executive function (oral trail making test, stroop test, or frsbe) * previous diagnosis of covid-19 confirmed via sars-cov-2 polymerase chain reaction (pcr) test (or reported experience of covid-19 symptoms with a documented positive antibody test or clinical diagnosis based on symptoms and accompanying physician's note) documented in the electronic medical record or in other existing medical records * access to and self-report of ability to connect wireless devices to a functional wireless network. * ability to follow written and verbal instructions (english) as assessed by the pi and/or coinvestigator. * able to comply with all testing and study requirements and willingness to participate in the full study duration exclusion criteria: * history of neurologic disorder prior to covid-19 diagnosis, such as parkinson's disease, multiple sclerosis, alzheimer's disease, stroke, brain tumor, or dementia. * history of severe mental illness (e.g., schizophrenia, psychosis, history of suicide attempt in the last year) or substance use disorder, recent history (in the past year) of symptoms of psychosis * participant is currently considered at risk for attempting suicide by the investigator, has made a suicide attempt within the past year, or is currently demonstrating active suicidal ideation or self-injurious behavior. * motor condition (e.g., physical deformity of the hands/arms) that prevents game playing as reported by the participant or observed by the investigator * recent history (within 6 months prior to screening/baseline) of substance use disorder * history of seizures (excluding febrile seizures), a tic disorder, significant tics, a current diagnosis of tourette's disorder. * color blindness as determined by self-report * regular use of psychoactive drugs other than antidepressants or benzodiazepines, including stimulants that in the opinion of the investigator may confound study data/assessments. * any other acute medical condition that may interfere with participation or interpretation of the results * previous exposure to akl-t01.
