Physical and Cognitive Aging Study in Older Adults
(PASOS)
What this study is about
Hispanic Americans are the fastest growing older adult group in the United States, disproportionally increasing the risk of an Alzheimer's disease and related dementias diagnosis. Efforts to reduce this risk and mitigate the related cognitive/physical declines are critical.
View original scientific description
Hispanic Americans are the fastest growing older adult group in the United States, disproportionally increasing the risk of an Alzheimer's disease and related dementias diagnosis. Efforts to reduce this risk and mitigate the related cognitive/physical declines are critical. The aim of this study is to assess the feasibility of enrolling older adults into an aging trajectory cohort, while generating preliminary data on associations of physical and cognitive aging trajectories. Our secondary objective is to generate preliminary data on the association of standard measures of physical activity and physical function with cognitive status. This study fits within our longitudinal research goal to reduce dementia incidence by understanding the mechanisms that drive the cognitive-physical aging trajectory.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- • Hispanic and non-Hispanic adults age 55-85 years, at least 8th grade education, community dwelling. Additional Inclusion for Hispanic Americans
- Self-identify as Hispanic American
- Report Spanish as primary language • No evidence of dementia or mild cognitive impairment based on cognitive screening \[i.e., Montreal Cognitive Assessment (MoCA) administered during Visit 1; ≥26 among non-Hispanic White, ≥25 among Hispanics, ≥24 among non-Hispanic Blacks (Milani et al., 2018)\]
Exclusion criteria
- Inability to provide informed consent
- Artificial joint or severe disability that would make it impossible or contraindicated performing the isokinetic test
- Sensory loss (vision, hearing) or motor deficits that would preclude participation in the experimental tasks or neuropsychological assessment
- Previous major strokes or other known significant brain abnormalities or diseases affecting the brain and/or cognition (e.g., Parkinson disease, multiple sclerosis, seizure disorder, brain surgery, moderate TBI, REM Behavior Sleep Disorder, untreated sleep apnea, etc.)
- Unstable and uncontrolled medical conditions (metastatic cancer, HIV, moderate-severe kidney disease, uncontrolled diabetes, uncontrolled hypertension, severe cardiac disease, etc.). No current cancer diagnosis.
- Current or past history of major psychiatric disturbance including schizophrenia, or active psychosis, bipolar disorder, current major depressive episode, current alcohol or substance abuse or history thereof within the past six months
- Use of antipsychotics, sedatives, or other medications with significant anticholinergic properties (due to potential influence on memory)
- Use of prescribed 'memory enhancing' medications, such as Aricept or Namenda
- Previous participation in a cognitive or physical activity training study within the last 6 months or current involvement in another study involving cognitive, physical or other intervention at the time of enrollment

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
