Nearly one in five older adults say their mental health has gotten worse since the pandemic began in March 2020, and an equal percentage say their sleep has suffered in that time too. More than one in four say they're more anxious or worried than before the COVID-19 era, according to a new poll of people age 50 to 80. But the poll also reveals hopeful signs that many older adults are showing long-term resilience.
In a new study from the Department of Anesthesiology and Center for Consciousness Science at Michigan Medicine, researchers identify a key area in the cortex that appears to be the gate of conscious awareness.
Researchers have identified a set of genes, called clock genes, that control circadian rhythms. But a more complicated gene network than previously known appears related to these rhythms. In Applied Physics Reviews, scientists detail a statistical model they are using to help identify the genes involved in this network. With help from other disciplines, they hope to fully understand how these genes work together to make different people more productive at different times of day.
Pioneering neural recordings in patients with Parkinson's disease by UC San Francisco scientists lays the groundwork for personalized brain stimulation to treat Parkinson's and other neurological disorders.
researchers from the Center for BrainHealth® at The University of Texas at Dallas are investigating a potential new early indicator of the decline toward Alzheimer's disease: measuring the energy metabolism of the living human brain using cutting-edge imaging techniques.
"We confirmed the longitudinal stability of social cognition deficits in cognitively-normal people with relapsing-remitting MS, mirroring the amygdala structural damage and psychological well-being," said Dr. Genova. "These results confirm that social cognition exerts a key role in MS, affecting individuals' everyday lives. Our research highlights the need to identify treatments to improve social cognition in this population."
Research compares effectiveness of seeking social support in real-life versus over social media.
Individuals living with severe Alzheimer's disease showed remarkable improvements in behaviour and cognition within days of receiving an innovative new treatment that delivered low doses of radiation, a recent Baycrest-Sunnybrook pilot study found.
Tiny 3-D models that mimic vital aspects of the human nervous system have been developed in a step that could accelerate drug research for neurological conditions such as multiple sclerosis (MS).
The potential uses of human pluripotent stem cells in medicine are hampered by the stress of growing in a cell culture dish, which can damage their DNA and lead to cell death. NCATS researchers have devised a small-molecule cocktail that can protect stem cells from stress. They suggest that the cocktail could enhance the potential uses of stem cells, ranging from treating diseases and conditions like Parkinson's disease and spinal cord injury to genome editing.
