Pilot Study: Lipoic Acid and Omega-3 Fatty Acids for Alzheimer's Prevention

Completed · Phase 1/Phase 2 · Has a placebo group

Conditions studied: Treated Hypertension

In brief

The primary aim of the pilot study is to provide data that can be used to better determine sample size for the design of a larger clinical trial. The pilot will evaluate the effectiveness of Lipoic Acid (LA) plus Omega-3 fatty acids (Omega-3) on preventing Alzheimer's Disease (AD). The investigators will also collect data to evaluate recruitment rate, safety, and compliance over the 12 month study period.

• Geriatric Depression Scale < 5
• General health status that will not interfere with the participant's ability to complete the study.
• Screening laboratory values within normal limits or, if abnormal, deemed clinically insignificant by the investigator
• Sufficient English language skills to complete all testing

You may not qualify if…

• Alzheimer's, Dementia or other neurodegenerative disease.
• Health conditions such as cancer diagnosed < 5 years prior to enrollment (prostate cancer gleason grade < 3 and non metastatic skin cancers are acceptable), liver disease, history of ventricular fibrillation or ventricular tachycardia, major psychiatric disorder, central nervous system diseases (e.g. brain tumor, seizure disorder)

• Lipoic Acid supplementation less than 1 month prior to enrollment
• Taking systemic corticosteroids, neuroleptics, antiparkinsonian agents, and/or narcotic analgesics. Low dose sinemet and dopamine agonist taken once a day for restless leg syndrome is not an exclusion.
• Contraindications to MRI, including: subjects with intrathecal pumps, stimulators, pacemakers, aneurysm clips, non-removable hearing aids, or metal fragments in the eyes. Other exclusion criteria include the inability to lie flat on the back for 40 minutes at a time or a self-reported history of claustrophobia. Subjects with a history of hip replacement and those with well-documented, verifiable, MRI-safe cardiac stents will not be excluded from the study.
