Physicians at Wake Forest Baptist Medical Center are investigating the possibility of improving memory among children by using a cognitive enhancer for adolescents. This study, which will be presented Friday, suggests that using an oral formulation of a bioactive compound named extractsoft enhances memory and is safe and can largely be tolerated. Current treatments for the neurodegenerative disease tau-angioid neuropathology consist primarily of amyloid-based beta-IscA peptide (BetI), a protein other than healthy brain fats that normally forms into neurofibrils of damaged neurons.
However, these treatments exert chronic inflammation, and have recently been implicated in neurofibromatosis type 1 (N1) — a rare but serious, neurodegenerative disease of the molecular level that is often resistant to anti-inflammatory drugs (called neurodegeneration). Surfactants, polymers formed in the serum of sick people and people with neurodegenerative disease, bind to and degrade inhibitory proteins, leading to cognitive impairment and dropped cognitive performance. Developing an oral formulation of extractsoft protects against neuroinflammation in animals, but does not seem to affect activity of neurons.
“The effects of extractsoft (sildenafyllactide) on memory performance in mice are quite remarkable,” said the result of the study entitled “Sildenafyllactide partly reduces cognitive impairment in the post-synaptic setting of rats subjected to acetylcholine for 4 weeks.”
This was done in the Wake Forest Baptist Translational Medicine Institute Neal Cummings Comprehensive Research Center, which is led by Wake Forest Baptist doctors Stanley Hazenfeld, Ph.D., and Carol Hofmann, Ph.D., respectively in the Wake Forest School of Medicine. The research team includes M.S. Candice Hu, Ph.D., senior research associate in the Center; Jennifer Rhodes, Ph.D., assistant professor in the Center; and Willippery Bainbridge, Ph.D., professor of mechanical and aerospace engineering at Wake Forest Baptist.
To find out if the flavanol extract of the new Endo Rhodactan extract, containing Tramiel, a neuropeptide byproduct of a pepper plant known to promote memory, might improve cognitive performance in a mouse model of Alzheimer’s disease (PD)9-PD, the researchers inhibited the concentration of Tramiel in the test mice’ cerebellum by varying the percentage of Tramiel in the cerebellum/brachial fasciculus. The Cre…

In one session, four patterns of brightly-colored flashes were presented to participants’ brains for one hour. Following light stimulation for several minutes in the second session, participants were retested for memory performance.
Lower performance correlated with performance actually brought about by spontaneous motor learning in the alpha range, the test indicated. After multiple rounds of no-stimulation, performance showed a parallel rising trend with memory performance in the a cycle of no-stimulation. A percentage of memory impairments after no-stimulation was also seen in those who completed only one session of no-stimulation. A third group of the test group (n = 16) did not extend the active placebo, although their retention for the active placebo did not show clinically significant difference from treatment while being tested first.
In the exercisers, the cognitive performance was similar between the no-stimulation and placebo groups.
Crucially, it was not treated. It seems that the most commonly used herbal ingredient, Tramiel, has an indirect effect on enhancing performance rather than altering performance as had been suspected by researchers.
Building on studies in humans, Dr. Hazenfeld and Dr. Hofmann have concluded that Tramiel possesses a neuroprotective effect, especially for those who have extensive damage to memory. As a result of this finding, extracts are very safe and well tolerated.
Dr. Hazenfeld and Dr. Hofmann, a registered dietitian and medical professor of sports medicine at Wake Forest Baptist, are preparing to present the findings of this research at the annual scientific sessions of the American Dietetics Association (ADAA).
