Emerging research on the effects of a novel magnesium compound of L-Threonic Acid Magnesium Salt (L-TAMS) containing Vitamins C and D on cognitive performance suggests that supplementation may benefit individuals with Alzheimer's disease (AD). This proof of concept will assess whether supplementation with Magtein (MGT), a constant release formula of Magnesium L-threonate, Vitamin C, and Vitamin D, is associated with changes in regional cerebral metabolism in elderly people with mild to moderate dementia.
This is an open-label, two-month trial consisting of 15-20 participants aged 60 and older with mild to moderate dementia. Subjects will receive 1,800 mg/day of MgT-1219 for a total of 60 days. They will be given neurocognitive testing, blood chemistries, and FDG-PET imaging at baseline, 60 days and more testing at 180 days to assess the acute effect of MgT-1219 on hippocampal and PFC-mediated executive function, attention, reasoning, and memory. Blood draws will be conducted prior to treatment initiation to assess kidney and liver function, complete blood count, fasting plasma insulin, and red blood cell magnesium.
Our outcome measures include a combination of neuropsychological testing and neuroimaging. These will be employed to measure changes in the degree of cognitive impairment within subjects over time, as well as between subjects in the intervention and control groups. FDG-PET imaging will be used to assess the degree of synaptic activity and density within subjects at different time points in the study. These measures will be supplemented by measures of, sleep quality, daytime sleepiness, depression, and activities of daily living.
|Study Type :||Interventional (Clinical Trial)|

|Official Title:||The Use of Magnesium L-Threonate for the Enhancement of Learning and Memory in People With Mild to Moderate Dementia|
|Study Start Date :||July 2014|
|Actual Primary Completion Date :||April 2016|
|Actual Study Completion Date :||July 2016|
All participants will orally take a total of 1800 mg/day for 60 days. Oral administration includes two pills 2 hours before bed time and one pill in the morning, each pill containing 600 mg of MgT-1219.
Dietary Supplement: Magtein
Other Name: magnesium l-threonate
- Cognitive Function [ Time Frame: Baseline to 6 Month Follow Up ]
Neurocognitive assessment - Domain-specific composite scores for the four following cognitive areas include:
1a) memory composite score
1b) attention composite score
1c) learning composite score
1d) executive function composite score
- FDG-PET [ Time Frame: Baseline to Day 67 ]
Brain imaging focusing on the following anatomical regions: medial temporal region (including hippocampus andentorhinal cortex), prefrontal cortex, parietotemporal cortex, posterior cingulate cortex
We will be focusing on two outcomes of interest:
2a) FDG-PET signal strength 2b) FDG-PET signal directionality
- RBC Magnesium chemistry [ Time Frame: Baseline to Day 60 ]Magnesium red blood cell levels
