Light Therapy Intervention in Individuals With Parkinson's Disease
What this study is about
The study looks to investigate the effects that light therapy delivered to the frontal cortex could have on Parkinson's disease related symptoms ( both cognitive and motor). The therapy is a non invasive technique that deliverers low level wavelength light to the front part of the head for 12 minutes. for this study the therapy will be done 3 times a week for 6 weeks.
View original scientific description
The study looks to investigate the effects that light therapy delivered to the frontal cortex could have on Parkinson's disease related symptoms ( both cognitive and motor). The therapy is a non invasive technique that deliverers low level wavelength light to the front part of the head for 12 minutes. for this study the therapy will be done 3 times a week for 6 weeks. To measure the potential effects on the therapy in Parkinson symptoms, we will do a set of cognitive and motor test before and after the intervention to measure any changes as well as control for any potential markers such as age, sex, disease level, medication and exercise.
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
- Diagnosis of Parkinson disease
Exclusion criteria
- Participants who are unable to comply with study visit/testing requirements (e.g. participants who cannot go off PD medication for the pre-, post-, and 3-month assessments).
- Participants who are unable to provide consent.
- Participants with a Deep Brain Stimulation (DBS) device.
- Participants who have a history of a psychiatric disorder
- Participants with PD who have other concurrent movement/neurological conditions, including dystonia, dementia, epilepsy etc.
- Participants with a clinical diagnosis of PD that is not considered primary (e.g. vascular parkinsonism) or participants where an atypical form of parkinsonism is suspected (e.g., progressive supranuclear palsy, multiple system atrophy).
- Participants with a history of cancer (whether treated with chemotherapy and/or radiotherapy or not).
- Participants with a history of a recent concussion or any facial, neck, or head injury within the last 6 months. UD IRB Approved: 03/12/2025 IRBNet ID#: 2277769-2 I/C from Rev. 01/2024 Page 3 of 10 Participant's Initial's \_\_\_\_\_\_\_\_
- Known injury or disease that might interfere with motor function in the proposed experiments (e.g., stroke, traumatic brain injury, extrapyramidal dysfunction, neuromuscular disease, orthopedic problems that impair movement).
- Participants with a history of photosensitivity.
- Participants who are not able to walk unassisted for 2 minutes

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.
