Dementia News and Research

RSS

Dementia is not a specific disease. It is a descriptive term for a collection of symptoms that can be caused by a number of disorders that affect the brain. People with dementia have significantly impaired intellectual functioning that interferes with normal activities and relationships. They also lose their ability to solve problems and maintain emotional control, and they may experience personality changes and behavioral problems, such as agitation, delusions, and hallucinations.

Scientists Uncover Inner Workings of Biomolecular Condensates Linked to ALS

Inside the cell reside many tiny assembly factories and warehouses that gather together all of the proteins and RNAs-which carry out instructions from our DNA-that a living being needs.

Scientists Map Five Major Epochs of Brain Wiring Across Human Life

Neuroscientists at the University of Cambridge have identified five "major epochs" of brain structure over the course of a human life, as our brains rewire to support different ways of thinking while we grow, mature, and ultimately decline.

Discovery Reveals Unexpected Role for OTULIN in Controlling Tau Expression

Scientists have uncovered a surprising mechanism by which a brain enzyme called OTULIN controls the expression of tau, the protein that forms toxic tangles in Alzheimer's disease.

Targeting Rhoa to Restore Function in Hematopoietic Stem Cells

Aging is defined as the deterioration of function overtime, and it is one of the main risk factors for numerous chronic diseases.

Rare Stress-Sensitive Neurons Hold the Key to Healthy Brain Blood Flow

While the exact causes of neurodegenerative brain diseases like Alzheimer's and dementia are still largely unknown, researchers have been able to identify a key characteristic in affected brains: reduced blood flow.

Study Reveals How Blood Vessels Drive Neuron Movement in the Brain

Researchers have discovered how newly created neurons depend on blood flow in the adult brain to travel from their site of origin to their final location.

Disrupted Circadian Rhythms Alter Gene Activity in Alzheimer’s Disease

Alzheimer's disease is notorious for scrambling patients' daily rhythms. Restless nights with little sleep and increased napping during the day are early indicators of disease onset, while sundowning, or confusion later in the day, is typical for later stages of the disease.

Cellular Switches Direct Supplies During Memory Formation

When we form a memory, brain cells need to deliver supplies to strengthen specific neural connections.

St. Jude Researchers Uncover Dual Role of ASPL in Stress Granule Assembly and Disassembly

Stress granules are droplet-like protein hubs that temporarily shield fragile RNA from cellular stresses such as toxins. VCP is a protein essential for breaking up stress granules and has been linked to neurodegenerative diseases.

How GBA Mutations Drive Cognitive Decline in Parkinson's Disease

Parkinson's disease causes both movement and cognitive deficits, and for a long time both were thought to be caused by the accumulation of a protein called alpha-synuclein in the brain.

Novel Fluorescent Reporter Technology Enables Real-Time Visualization of Apoptosis Inside Cells

Cells in our body are programmed to die after a certain period of time-a natural process known as apoptosis or "cell suicide."

Genetic Signatures of Neural Progenitor Cells Uncovered in the Adult Brain

For much of the 20th century it was thought that the adult brain was incapable of regeneration. This view has since shifted dramatically and neurogenesis – the birth of new neurons – is now a widely accepted phenomenon in the adult brain, offering promising avenues for treating many neurological conditions.

Feline Dementia May Explain Synapse Loss in Alzheimers

The study uncovers amyloid-beta's role in glial-mediated synapse loss in feline cognitive dysfunction, enhancing understanding of Alzheimer's disease.

Tracing the Genetic Mosaic of India Through Ancient Ancestry and Modern Genomes

India's population is genetically one of the most diverse in the world, yet it remains underrepresented in global datasets.

Proteomic Signature in Blood Predicts Dementia and Diabetes Risk

A blood-based proteomic signature predicts healthspan, linking protein levels to disease risk and mortality, paving the way for targeted aging interventions.

New Study Links Gut Health to Cognitive Loss in Parkinson’s

Investigating gut bacteria's impact on Parkinson's, this study highlights potential dietary and hygiene interventions to support brain health.

UC Davis Study Links Specific microRNAs to Mental and Neurological Disorders

A study in Nature Aging from researchers at the UC Davis School of Medicine has identified specific microRNAs - non-coding RNAs that regulate gene expression within cells - that likely contribute to bipolar disorder, depression, schizophrenia, post-traumatic stress disorder (PTSD) and Parkinson's disease.
