Choline Part 2

Tomorrow we will get back to the green tea extract and DYRK1 A gene because there are more issues to discuss but today let's look at one little study that showed positive results for the Down syndrome mouse.
Here is the study abstract:
Behav Neurosci. 2010 Jun;124(3):346-61.

Perinatal choline supplementation improves cognitive functioning and emotion regulation in the Ts65Dn mouse model of Down syndrome.

In addition to mental retardation, individuals with Down syndrome (DS) also develop the neuropathological changes typical of Alzheimer's disease (AD) and the majority of these individuals exhibit dementia. The Ts65Dn mouse model of DS exhibits key features of these disorders, including early degeneration of cholinergic basal forebrain (CBF) neurons and impairments in functions dependent on the two CBF projection systems; namely, attention and explicit memory. Herein, we demonstrate that supplementing the maternal diet with excess choline during pregnancy and lactation dramatically improved attentional function of the adult trisomic offspring. Specifically, the adult offspring of choline-supplemented Ts65Dn dams performed significantly better than unsupplemented Ts65Dn mice on a series of 5 visual attention tasks, and in fact, on some tasks did not differ from the normosomic (2N) controls. A second area of dysfunction in the trisomic animals, heightened reactivity to committing an error, was partially normalized by the early choline supplementation. The 2N littermates also benefited from increased maternal choline intake on 1 attention task. These findings collectively suggest that perinatal choline supplementation might significantly lessen cognitive dysfunction in DS and reduce cognitive decline in related neurodegenerative disorders such as AD.

They supplemented with choline which crosses the Blood Brain Barrier (protective barrier for the brain) with a transport system. Phosphatidylcholine (PC) passes through the BBB because it  is fat soluble. I'm always thinking about making it as easy as I can for the body. So, my choice of supplementation is PC as opposed to free choline.
