Validation for Treatment of the Mental Challenges in Down Syndrome

The following was written by Linda Blevins, one of Changing Minds Foundation's founding members. Her son with DS is 16 and been on treatment for 5 years.

Choline improves Cognition in Down syndrome mice models.
The Changing Minds Foundation protocol is based upon scientific research. The newest research supports the CMF science based protocol for the treatment of cognitive challenges in Down syndrome.
CMF protocol recommends the use of phosphotidyle choline (PC) rather than just plain choline. PC is more potent and is the active form the body needs. The link to the CMF web site explains more about PC.

A number of scientific studies have vailidated the CMF protocol which targets critical cycles that function poorly in Down syndrome. These cycles produce invaluable neurotransmitters that are needed for learning, focus, attention, memory production and growing neurons for connection and signalling. (Who doesn't think that's important???)..Though sometimes we don't appreciate the new behaviors that come from growing a brain. Yet, I love the educational progress. Jordan's current school lessons examples:

More Choline for Pregnant, Nursing Women Could Reduce Down Syndrome Dysfunction, Guard Against Dementia

ScienceDaily (June 4, 2010) — More choline during pregnancy and nursing could provide lasting cognitive and emotional benefits to individuals with Down syndrome and protect against neurodegenerative conditions such as Alzheimer's disease, suggests a new Cornell study of mice.
The findings, published June 2 in Behavioral Neuroscience, could help lead to increasing the maternal dietary recommendations for choline (currently 450 milligrams a day during pregnancy, 550 milligrams for lactation), a nutrient found in egg yolks, liver, nuts and such vegetables as broccoli and cauliflower.

"We found that supplementing the maternal diet with additional choline resulted in dramatic improvements in attention and some normalization of emotion regulation in a mouse model of Down syndrome," said lead author Barbara Strupp, professor of nutritional sciences and of psychology. The researchers also found evidence for "subtle, but statistically significant, improvement in learning ability in the non-Down syndrome littermates."

In addition to mental retardation, Down syndrome individuals often experience dementia in middle age as a result of brain neuron atrophy similar to that suffered by people with Alzheimer's disease. Strupp noted that the improved mental abilities found in the Down syndrome mice following maternal choline supplements could indicate protection from such neurodegeneration "in the population at large."

Strupp and her co-authors tested Down syndrome model mice born from mothers fed a normal diet and those given choline supplements during their three-week pregnancy and three-week lactation period, as well as normal mice born from mothers with and without additional choline. The choline-supplemented mothers received approximately 4.5 times more choline (roughly comparable to levels at the higher range of human intake) than unsupplemented mothers.

At six months of age, the mice performed a series of behavioral tasks for about six months to assess their impulsivity, attention span, emotion control and other mental abilities.

In addition to dramatic improvements in attention, the researchers found that the unsupplemented Down syndrome model mice became more agitated after a mistake than normal mice, jumping repeatedly and taking longer to initiate the next trial, whereas the choline-supplemented Down syndrome model mice showed partial improvement in these areas.

"I'm impressed by the magnitude of the cognitive benefits seen in the Down syndrome model mice," Strupp said. "Moreover, these are clearly lasting cognitive improvements, seen many months after the period of choline supplementation."

Strupp noted that the results are consistent with studies by other researchers that found increased maternal choline intake improves offspring cognitive abilities in rats. However, this is the first study to evaluate the effects of maternal choline supplementation in a rodent model of Down syndrome. This is also one of the few studies that has evaluated offspring attentional function and effects in mice, rather than rats, Strupp noted.

Previous studies of humans and laboratory animals have shown that supplementing the diets of adults with choline has proven to be largely ineffective in improving cognition. "Although the precise mechanism is unknown, these lasting beneficial effects of choline observed in the present study are likely to be limited to increased intake during very early development," Strupp said.

The study, funded in part by the National Institutes of Health (NIH), was part of the dissertation of Jisook Moon, Ph.D. '06. Other Cornell collaborators included Myla Strawderman, research associate in nutritional sciences; David Levitsky, professor of nutrition and of psychology; May Chen '07 and Shruti Gandhy '07.

Strupp and collaborators have received additional NIH funding to study the neural mechanisms underlying the positive cognitive effects of perinatal choline supplementation observed in this study.

  1. I love this study. I am a believer that good nutrition make the different in the womb for our kids with Trisomy 21. I am not a scientist, but a mom who followed her instincts during pregnancy and I ate as healthy as it can be. Results I have a child with Down syndrome who his therapists has said his greatest skills are cognition and fine motor. Please keep doing this type of research. Other research should be doing is eliminating artificial sugar from the diet of pregnant women expecting kids with Trisomy 21. This may help in the improvement of low muscle tone before birth.
