The LARRS is currently enrolling volunteers with mild cognitive impairment and healthy control subjects for a study.

Can we detect problems with thinking functions before they emerge in older adults at risk of Alzheimer's disease?

LARRS researchers want to know:
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?

Lab team members will record participants' brain waves, pupil dilation, and heart rate with non-invasive tools while engaging in different cognitive tests. This will take two hours. If eligible, participants may be compensated $50 for their time.

Individuals are eligible to participate if meeting the following 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.

Can we detect small thinking impairments in adults with multiple sclerosis by measuring their pupil size?

LARRS researchers want to know:
Is it possible to use non-invasive neurophysiological measures as potential markers of subtle cognitive impairments in individuals who are at risk for developing and worsening cognitive impairment in multiple sclerosis?

Lab team members will record participants' pupil dilation with non-invasive tools while engaging in different cognitive tests. This will take two hours. If eligible, participants may be compensated $50 for their time.

Individuals are eligible to participate if meeting the following criteria:

  1. Being cognitively intact or having mild cognitive impairment.
  2. Aged 18-65 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.

The LARRS is currently enrolling commercial truck drivers of any age for a study.

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

What LARRS researchers want to accomplish:
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.

Individuals are eligible to participate if they meet thefollowing criteria:

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

Compensation will be provided.

For more information about this study and its goals, please contact Iarina Devos, research coordinator, at idevos@kumc.edu, 913-588-7459 (711 TTY).

Coronavirus Update
In accordance with institutional policy regarding the COVID-19 coronavirus situation, research and driving evaluation activities have been suspended at this time. Updates will be posted here when available. Sorry for any inconvenience.

Activities and Updates

Researchers at the Medical University of South Carolina accepted LARRS co-director Hannes Devos to attend their Training in Grantsmanship for Rehabilitation Research workshop January 7-11 in Charleston, S.C. Organized by the National Institutes of Health for rehabilitation science grants, this intensive grant-writing program brings together nationally recognized mentors to foster future success in obtaining research grant support at the national level.

LARRS team member Amber Conn received a Parkinson's Foundation grant to conduct Mobilizing Parkinson's (balance, movement driving) workshops across Kansas and Missouri. This grant also provides free driving assessments to the Parkinson's community.

LARRS co-director Abiodun Akinwuntan has been appointed as Academic Editor of Plos One Journal.
