Montelukast Therapy for Alzheimer's Disease

Start: September 25, 2019
End: October 2022
Enrollment: 150

What Is This Study About?

This clinical trial will test montelukast, a medication used to treat asthma, on the memory and thinking in people with mild cognitive impairment and early Alzheimer's dementia. Participants will be randomly assigned to take either the study drug or a placebo, starting at 10 mg daily and rising to 20 mg and 40 mg, for one year. Researchers will look at brain imaging, cognitive function, and biomarkers from a lumbar puncture to measure the effect.
