Alzheimer’s therapy for people with Down syndrome

Posted on by

Alzheimer; News from the web:

Researchers at the University of Colorado School of Medicine have been awarded a $4.6 million, five-year grant by the National Institute on Aging to study whether a potential Alzheimer’s disease treatment is safe and effective in improving cognitive function in young adults with Down syndrome.

Huntington Potter, PhD, professor of neurology, and Peter Pressman, MD, assistant professor of neurology, are principal investigators on the study of sargramostim, which is also know by the brand name Leukine, an FDA-approved drug with nearly 30 years of safe use in numerous patient populations.

“This is the first clinical trial in years to target cognition in people with Down syndrome,” said Potter, who is director of University of Colorado Alzheimer’s and Cognition Center. “We are breaking new ground in studying both of these disorders – Down syndrome and Alzheimer’s disease. We hope that this therapy will greatly improve their quality of life.”

The importance of sleep in a new study

Disrupted sleep is common in late life, the study authors wrote, and associated with changes in cognitive function — the mental capacity for learning, thinking, reasoning, problem-solving, decision-making, remembering and paying attention.Age-related changes in sleep have also been linked with early signs of Alzheimer’s disease, depression and cardiovascular disease, so the authors investigated possible associations between self-reported sleep duration, demographic and lifestyle factors, subjective and objective cognitive function, and participants’ levels of beta amyloid.

Key mechanisms behind synapse degeneration in Alzheimer’s brain discovered

Alzheimer; News from the web:

Neurobiologists have uncovered the long-sought-after mechanisms behind the maintenance and decline of key synapses implicated in brain disorders such as Alzheimer’s disease. The researchers identified the main components driving amyloid beta-associated synapse degeneration, which is found in the brains of people with Alzheimer’s. The findings suggest an alternative approach to addressing neurodegenerative disorders: protect synapses by directly blocking the toxic actions of amyloid beta.
