Participate in a Study

The LARRS is currently enrolling volunteers with Parkinson’s disease and healthy control subjects for a study:
Increased cognitive effort during dual-tasking and its relationship with falls in Parkinson's disease

We want to know:
How much mental effort, measured by pupil dilation, is needed during dual-tasking, and is there a relationship between increased mental effort and falls in Parkinson’s disease.

We will record participant's pupil responses during concurrent cognitive and motor activities. This will take two hours. These pupil recordings are not invasive. If eligible, participants may be compensated $50 for this time.

  1. Are 60 years of age or older
  2. Have either a diagnosis of Parkinson's disease or no neurological condition at all
  3. Have no problems with eyes or pupils, except for corrective glasses or contact lenses
  4. Are English speaking

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?

We 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?

We 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?

We 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?

We 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

Activities and Updates

Akinwuntan and Devos from LARRS presented on driving simulation for drivers with medical conditions at the annual Transportation Research Board Conference.

Jamie Myers, Abiodun Akinwuntan, and Hannes Devos were awarded the KU Cancer Center Pilot Grant for their study "Task-Evoked Pupillary Response: Assessment of Cognitive Effort for Breast Cancer Survivors"

Hannes Devos and Katie Siengsukon received research funding from the Department of Physical Therapy and Rehabilitation Science to study eye metrics of cognitive fatigability and sleepiness in multiple sclerosis.

Melike Kahya, a student in the doctoral program in rehabilitation science, has been awarded a full-time training stipend in the Kansas Training Program in Neurological and Rehabilitation Sciences, an Institutional Training Program funded by the National Institutes of Health.

Melike Kahya has been selected as an awardee of a Mabel A. Woodyard Fellowship in Neurodegenerative Disorders. This fellowship will provide her $30,000 support for tuition, research expenses, and academic traveling.
