July 23, 2012 (Vancouver, British Columbia) — Administration of a medical food designed to improve synaptic dysfunction is associated with continuous memory improvement in patients with mild Alzheimer's disease (AD), new research shows.
Presented here at the Alzheimer's Association International Conference (AAIC) 2012, results from an open-label extension (OLE) trial of a medical nutrition product (Souvenaid, Nutricia/Danone) showed that memory performance continued to improve in drug-naïve patients with mild AD for up to 48 weeks.
These latest OLE results immediately follow those of the double-blind, randomized controlled Souvenir II study, published in the July issue of the Journal of Alzheimer's Disease, which showed significant improvement in memory performance compared with placebo over 24 weeks.
As presented by Philip Scheltens, MD, PhD, professor of cognitive neurology and director of the Alzheimer Center at the VU University Medical Center in Amsterdam, the Netherlands, the results from the 24-week OLE study "were exactly what we hoped for."

"There was no ceiling effect," he said.
Furthermore, study participants who were in the placebo group in the randomized controlled period of the trial and who were switched to the active treatment in the OLE study also experienced significant memory improvement.
"The bottom line is that we have now conducted 2 large studies with this medical food that aims to restore the function of synapses in mild to very mild Alzheimer's disease and have proven that it improves memory," Dr. Scheltens told Medscape Medical News.
He added that the findings also show that Souvenaid is "very safe and well tolerated" and confirm the results of the Souvenir I trial, the very first proof of concept study, which was published in the journal Alzheimer's & Dementia and reported byMedscape Medical News at that time
