Results from quantitative MRI and neuropsychological testing show unprecedented improvements in ten patients with early Alzheimer’s disease (AD) or its precursors following treatment with a programmatic and personalized therapy. Results from an approach dubbed metabolic enhancement for neurodegeneration are now available online in the journal Aging.
The study, which comes jointly from the Buck Institute for Research on Aging and the UCLA Easton Laboratories for Neurodegenerative Disease Research, is the first to objectively show that memory loss in patients can be reversed, and improvement sustained, using a complex, 36-point therapeutic personalized program that involves comprehensive changes in diet, brain stimulation, exercise, optimization of sleep, specific pharmaceuticals and vitamins, and multiple additional steps that affect brain chemistry.
“All of these patients had either well-defined mild cognitive impairment (MCI), subjective cognitive impairment (SCI) or had been diagnosed with AD before beginning the program,” said author Dale Bredesen, MD, a professor at the Buck Institute and professor at the Easton Laboratories for Neurodegenerative Disease Research at UCLA, who noted that patients who had had to discontinue work were able to return to work and those struggling at their jobs were able to improve their performance. “Follow up testing showed some of the patients going from abnormal to normal.”
One of the more striking cases involved a 66-year old professional man whose neuropsychological testing was compatible with a diagnoses of MCI and whose PET scan showed reduced glucose utilization indicative of AD. An MRI showed hippocampal volume at only the 17th percentile for his age. After 10 months on the protocol a follow-up MRI showed a dramatic increase of his hippocampal volume to the 75th percentile, with an associated absolute increase in volume of nearly 12 percent.
In another instance, a 69-year old professional man and entrepreneur, who was in the process of shutting down his business, went on the protocol after 11 years of progressive memory loss. After six months, his wife, co-workers and he noted improvement in memory. A life-long ability to add columns of numbers rapidly in his head returned and he reported an ability to remember his schedule and recognize faces at work. After 22 months on the protocol he returned for follow-up quantitative neuropsychological testing; results showed marked improvements in all categories with his long-term recall increasing from the 3rd to 84th percentile. He is expanding his business.
