Blood plasma reveals shared pathways in neurodegenerative diseases (Links to an external site)

Carlos Cruchaga

Scientists know that many proteins and pathways are involved in the development and progression of neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease and frontotemporal dementia (FTD), and that these proteins can be detected in the plasma of people with the conditions. But it hasn’t been clear exactly which proteins are distinct to one disease […]

AI-based brain-mapping software receives FDA market authorization (Links to an external site)

A new AI-based technology that rapidly maps the brain to locate sensitive areas that control speech, vision, movement and other critical functions has received authorization from the Food and Drug Administration (FDA), enabling it to be marketed to hospitals with the aim of enhancing the precision of neurosurgeries. The technology was developed by researchers and […]

NIH-funded Phase 2B clinical trial for NMDAR encephalitis treatment continues to successfully enroll patients at dozens of sites, including WashU Medicine

The ExTINGUISH NMDAR Encephalitis Trial

An ongoing clinical trial designed to answer critical questions regarding treatment protocols for anti-NMDA receptor encephalitis, a relatively rare but often devastating condition, is continuing to expand trial sites and enroll participants, building excitement in the medical and patient communities. At Washington University School of Medicine in St. Louis, David Clifford, MD, the Melba and […]

Research untangles role of stress granules in neurodegenerative disease (Links to an external site)

Scientists from St. Jude Children’s Research Hospital and Washington University in St. Louis report mechanistic insights into the role of biomolecular condensation in the development of neurodegenerative disease. The collaborative research, published in Molecular Cell, focused on the interactions that drive the formation of condensates versus the formation of amyloid fibrils and how these relate to […]

Sleep aid blocks neurodegeneration in mice (Links to an external site)

A new study by WashU Medicine researchers suggests that lemborexant and sleep aids that work the same way could help treat or prevent damage caused by harmful buildup of the protein tau in multiple neurodegenerative diseases, including Alzheimer’s. Shown are cross-sections of brain tissue from two mice genetically prone to tau accumulation. Treatment with lemborexant (right) results in larger volume in the hippocampus (central purple spiral), important for memory, and a smaller gap in brain tissue (white space) compared with no treatment (left).

A common sleep aid restores healthier sleep patterns and protects mice from the brain damage seen in neurodegenerative disorders, such as Alzheimer’s disease, according to new research from Washington University School of Medicine in St. Louis. The drug, lemborexant, prevents the harmful buildup of an abnormal form of a protein called tau in the brain, […]

Overlooked cell type orchestrates brain rewiring (Links to an external site)

Colored bursts indicate activity in astrocyte cells in a mouse brain. Exposure to a signaling chemical called norepinephrine triggers a coordinated wave of activity. The lab of Thomas Papouin, assistant professor of neuroscience at WashU Medicine, discovered that astrocytes are responsible for modifying brain activity in response to norepinephrine.

Researchers at Washington University School of Medicine in St. Louis have upended decades-old dogma of how connections between brain cells are rearranged during states of heightened vigilance or attention. The team found that a brain chemical associated with alertness, attention and learning alters brain connectivity and function not by acting directly on neurons, the cells […]

WashU Medicine researchers identify potential for repurposing Prozac to treat rare epilepsy (Links to an external site)

Christina Gurnett, MD, PhD, and Lawrence Salkoff, PhD, are lead authors on a case report that describes how Prozac can be used in the treatment of children with rare forms of epilepsy.

A team of WashU Medicine researchers has discovered a promising new use for Prozac, which is the brand name of the antidepressant fluoxetine, in the treatment of children with rare forms of epilepsy. In a Frontiers of Pharmacology case report published earlier this year, the researchers describe how fluoxetine treatment of two siblings with developmental and epileptic encephalopathy […]

Most people say they want to know their risk for Alzheimer’s dementia, fewer follow through (Links to an external site)

As researchers make progress in understanding how Alzheimer’s disease develops, there are growing opportunities for healthy research participants to learn their risk of developing Alzheimer’s disease dementia in the future. While many organizations often advocate for investigators to share risk estimates with individual participants, there are ethical concerns around doing so, given that there are […]
