Completed

• Conditions: Healthy Adults

• Registration Number: NCT06376175
• Lead Sponsor: Lumos Labs, Inc.

Brief Summary

Healthy volunteers ages 25-40 from the general US population who meet the eligibility criteria and are enrolled will (a) play Lumosity games at least 20 times each in under 60 days and (b) then complete one session of task-based functional magnetic resonance imaging (fMRI) while playing Lumosity games.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 37

Inclusion Criteria

• Subjects 25-40 years of age.
• Ability to understand and speak English, follow written and verbal instructions (English), and give informed consent (English), as assessed by the PI or project manager.
• Ability to comply with all the testing and study requirements, including the ability to independently complete daily, online Lumosity games on a reliable, internet-connected device.
• Geographical location within 100 miles of the study imaging center.

Exclusion Criteria

• Current, controlled (requiring treatment) or uncontrolled psychiatric diagnosis, including but not limited to posttraumatic stress disorder, psychosis, bipolar illness, pervasive developmental disorder, severe obsessive compulsive disorder, severe depressive or severe anxiety disorder, conduct disorder, attention- deficit/hyperactivity disorder, or other symptomatic manifestations that in the opinion of the PI may confound study data/assessments.
• Current, controlled (requiring treatment) or uncontrolled neurological diagnosis, including but not limited to Alzheimer's Disease, other dementias, mild cognitive impairment, Huntington's Disease, Parkinson's Disease, multiple sclerosis, stroke, epilepsy, aphasia, or other condition that in the opinion of the PI may confound study data/assessments.
• Any other medical condition in the last 90 days that in the opinion of the PI may confound study data/assessments.
• Has been under the care of a caretaker or has not been living independently in the last 90 days.
• In the last three years has used online brain training programs (e.g., BrainHQ, Lumosity, Peak) for more than two weeks continuously.
• Known sensitivity (such as headaches, dizziness, nausea) to bright, stimulating video displays.
• History of seizures (excluding febrile seizures), or significant motor or vocal tics, including but not limited to Tourette's Disorder and photo-sensitive epilepsy.
• Visual acuity that cannot be corrected that prevents or negatively impacts computer activity.
• Pregnancy, or strong likelihood of pregnancy.
• Left-handed or ambidextrous.
• Unwillingness or inability to comply with imaging safety protocols. Inability includes but is not limited to metal implants or exposure to shrapnel.
• Any other condition that in the opinion of the PI may confound study data.
