Outcome Measures

Primary Outcomes (2)

  • Glucose Metabolism

    Continuous glucose meter 7-10-day average glucose readings before/after open-label treatment with the ketone ester in patients with PD, Parkinson's disease dementia/Lewy body dementia, and normal controls. Healthy fasting blood glucose ranges from 70 to 99 milligrams per deciliter (mg/dL), with a healthy maximum of 180 mg/dL within 2 hours of eating meals.

    Pre and post approximately 30 days of intervention

  • Clinical Dementia Rating Scale Score

    The clinical dementia rating scale is a measure of functional and cognitive performance relevant to dementia. It is scored from 0 (normal) to 3 (severe dementia). The clinical dementia rating scale will be assessed in patients with Parkinson's disease, Parkinson's disease dementia/Lewy body dementia, and healthy controls before and after open-label treatment with the ketone ester.

    Pre and post approximately 30 days of intervention

Study Arms (3)

Parkinson Disease

EXPERIMENTAL

Participants will take the ketone ester supplement for 30 days +/- 7 days. For days 1 through 7, participants will take 12.5g (25mL) of the ketone ester supplement (KetoneAid) TID, and on day 8, the dose will be increased to 25g (50mL) three times daily (TID) as tolerated. KE dose will be titrated down to a tolerated level if necessary.

Dietary Supplement: Ketone Ester (R)-3-Hydroxybutyl (R)-3-Hydroxybutyrate

Parkinson Disease Dementia/Lewy Body Dementia

EXPERIMENTAL

Participants will take the ketone ester supplement for 30 days +/- 7 days. For days 1 through 7, participants will take 12.5g (25mL) of the ketone ester supplement (KetoneAid) TID, and on day 8, the dose will be increased to 25g (50mL) TID as tolerated. KE dose will be titrated down to a tolerated level if necessary.

Dietary Supplement: Ketone Ester (R)-3-Hydroxybutyl (R)-3-Hydroxybutyrate

Healthy Controls

EXPERIMENTAL

Participants will take the ketone ester supplement for 30 days +/- 7 days. For days 1 through 7, participants will take 12.5g (25mL) of the ketone ester supplement (KetoneAid) TID, and on day 8, the dose will be increased to 25g (50mL) TID as tolerated. KE dose will be titrated down to a tolerated level if necessary.
