Abstract
Caprylidene is a ketogen that, when metabolized, produces the ketones beta-hydroxybutyrate and acetoacetate, which can cross the blood brain barrier. It has been hypothesized that ketone bodies can be used as an alternate energy source by neurons with impaired glucose utilization. Caprylidene has been shown to improve cognition in patients with mild-to-moderate Alzheimer's disease (AD) who lacked an AD-predisposing allele (ɛ4) of the gene for apolipoprotein E. In this pilot study, we examined the effects of caprylidene on regional cerebral blood flow (rCBF) in patients with mild to moderate AD. Sixteen subjects with mild-to-moderate AD, based on NINCDS-ADRDA criteria, were enrolled in a double-blinded, placebo-controlled, randomized clinical trial. Fourteen subjects received treatment with caprylidene, and 2 subjects were given placebo. Subjects received 4 15O-water PET scans over the course of the study to assess rCBF: once before receiving a standard caprylidene or placebo dose and 90 min after the dose, on the first day and after 45 days of daily caprylidene or placebo consumption. The scans were examined by standardized volumes of interest (sVOI) and voxel-based statistical parametric mapping (spm) methods of analysis. Subj...Continue Reading
