A study in mice concluded that memory problems associated with age may be driven by our gut microbiome and that the vagus nerve may be key to reversing it.

Researchers identified in mice a microbiome–gut–brain pathway in which age-associated changes in gut microbes increase medium-chain fatty acids that impair vagal sensory signaling and hippocampal ...

Researchers create a massive single-cell atlas of the aging mouse brain, revealing how epigenetic changes and "jumping genes" drive neurodegeneration.

When myelin breaks down, white matter in the brain deteriorates, a change commonly seen with aging. At the same time, microglia, the brain’s primary immune cells, can shift from protective responders ...

Neurodegenerative diseases affect more than 57 million people globally. The incidence of these diseases, from Alzheimer's to Parkinson's to ALS and beyond, is expected to double every 20 years. Though ...

Salk researchers create epigenetic atlas of cell type-specific changes in the aging mouse brain, representing eight different brain regions and 36 different cell types to show clear epigenetic ...

Surviving cancer at a young age may come with an unexpected cost: faster aging at both the cellular and brain levels. Researchers found that survivors often show signs of being biologically older than ...

New research suggests childhood cancer survivors may experience accelerated biological aging from treatments, potentially ...

An international research team has uncovered new insights into healthy brain aging. The researchers found that aging leads to the accumulation of defective energy molecules in the brains of aged mice, ...

As we age, the composition and function of proteins in the brain change, affecting how well our brain performs later in life—influencing memory, responsiveness, and the risk of neurodegenerative ...

There's research connecting poor dental care to higher dementia risk. We explore the connection between oral health and brain function and share practical steps to protect your cognitive health ...

You’ve likely experienced it: a day when your mind just feels a bit slow — finding the right words takes effort, processing feels sluggish, and recalling information takes longer than usual. People ...
