Participate in a Study

We are currently recruiting study participants for two active studies in LARRS lab.

Currently enrolling:

  • Volunteers with mild cognitive impairment
  • Healthy control subjects

With this study, we are investigating whether we can detect problems with thinking functions before they emerge in older adults at risk of Alzheimer's disease. The study also asks: Is it possible to use non-invasive neurophysiological measures as potential markers of subtle cognitive impairments in individuals who are at risk for developing Alzheimer’s disease?

In this pursuit, our lab team members will record participants' brain waves, pupil dilation and heart rate using non-invasive tools while engaging in different cognitive tests. The study will take two hours. Eligible participants may be compensated $50 for their time.

Eligibility Criteria

  1. Being cognitively intact or having mild cognitive impairment
  2. Aged more than 60 years old
  3. Have no history of other neurological conditions
  4. Have no problems with eyes or pupils, except for corrective glasses or contact lenses
  5. Have no cardiac rhythm disorders

Assessing and Improving the Cognitive and Visual Driving Fitness of Commercial Truck Drivers

Currently enrolling:

  • Commercial truck drivers of any age

With this study, LARRS researchers hope to assess drivers’ cognitive and visual fitness, establish the usefulness and effectiveness of these tests to drivers before embarking on the journey, identify potential risk factors that contribute to unsafe driving, and evaluate the effect of an intervention program to improve reduced visual, cognitive, and driving skills.

The subjects will need to come in for a visual, cognitive and mobility testing evaluation. This will take two hours. The participants will be asked to come in once a year for three years. We will give them useful information, including height, weight, BMI, that will assist them in any concerns we may find.

Results will only be kept with the research team. The goal of this study is to help participants remain safer drivers for longer.

Eligibility Criteria

  1. 18 years of age or older.
  2. Have a valid Commercial Driving License.

Compensation will be provided.
