About this study
Official title: A Crossover, Randomized Block Sequence, Double-Blind, Placebo-Controlled Trial for Nicotinamide Riboside in Subjective Cognitive Decline and Mild Cognitive Impairment in Aging
In this research study we want to learn more about whether taking Niagen, a daily supplement containing a form of Vitamin B3, will improve cognitive function, mood, and daily activity in people with Subjective Cognitive Decline (SCD) or Mild Cognitive Impairment (MCI).
Read the detailed description
Over a 6 month period, we will ask study participants to take both Niagen or a placebo for 8 weeks each and complete research visits ever 4 or 8 weeks. Most research visits will involve a blood draw, cognitive testing, and mood questionnaires. We will ask you to come to our center 4-5 times to complete some study activities in-person. There will be an option to participate in a lumbar puncture sub-study, in which participants would have up to 3 lumbar punctures. There will also be an option to participate in an MRI sub-study, in which participants would have up to 3 MRIs over the course of the study. In between research visits, we will also ask the participants to wear a Fitbit activity tracker and play computerized brain games a few times a week. This will enable us to get a snapshot of each subject's functioning levels day to day and better determine whether or not the supplement is having an effect on the participant.

What is being measured
The primary outcome is the main question the study is designed to answer.
The Effect of Niagen vs PBO on Cognition as Measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).
The primary outcome of this study will be objective measures of cognitive performance measured with the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) at baseline, crossover, and the end of study. RBANS has a mean score of 100 with a standard deviation of 15. Scores range from 40 to 160. Higher scores indicate normal cognition.
Measured: From baseline through end of study at 16 weeks
