INTRODUCTION: Interest has grown in lithium's neuroprotective properties in neurodegenerative illnesses. We discuss the design, rationale, and implementation of a pilot feasibility, double-blind, randomized placebo-controlled trial (RCT) examining whether lithium can delay cognitive decline in older adults with mild cognitive impairment (MCI).
METHODS: The study launched in September 2017. The goal was to enroll 80 community-dwelling participants ≥ 60 years with MCI into an RCT in which they would participate for 2 years with baseline and follow-up assessment of cognition, brain imaging, and plasma-based biomarkers. Participants were randomized to lithium or placebo (1:1).
RESULTS: We enrolled 80 MCI older adults into the RCT. Baseline characteristics included a mean (standard deviation) age of 72 (7.7) years with 35 male and 45 female participants. Seventy-five participants had positron emission tomography imaging for amyloid beta (Aβ), and 66 completed 7T magnetic resonance imaging. Twenty-one participants were Aβ+ and 54 were Aβ-.
DISCUSSION: The study successfully enrolled 80 participants into an RCT examining whether lithium delays cognitive decline. The main study results will be forthcoming.
CLINICAL TRIAL REGISTRATION: NCT03185208.
HIGHLIGHTS: Eighty adults ≥ 60 years with mild cognitive impairment entered a placebo-controlled randomized controlled trial evaluating lithium's neuroprotective properties.Participants were followed for 2 years with baseline and follow-up evaluations at 1 and 2 years that included neurocognitive assessment, ultra-high-field structural neuroimaging, positron emission tomography imaging for amyloid beta and tau, and plasma-based biomarkers.Study results will be forthcoming.
