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.

Study shows how tau aggregates promote Alzheimer’s disease

If looked deep into the brain of a patient with Alzheimer’s disease or those suffering from the most types of dementia or the concussion-associated syndrome, called chronic traumatic encephalopathy (CTE), there would be hairball-like tangles of a protein known as tau—a common suspected culprit.

Study shows that neural stem cells age quickly

A research team has revealed that neural stem cells (NSCs)—that is, the stem cells of the nervous system—age quickly.

Study finds an amyloid link between melanoma and Parkinson’s disease

Parkinson’s disease is a neurodegenerative disorder and melanoma is a type of skin cancer but on the surface, these disorders do not seem to have much in common.

Study sheds new light on age-related neurodegenerative disorders

Neurons cannot simulate their DNA and hence they work continuously to repair any damage caused to their genome.

Retinoic acid induces synaptic plasticity in the human brain

Neuroscientists agree that a person's brain is constantly changing, rewiring itself and adapting to environmental stimuli. This is how humans learn new things and create memories. This adaptability and malleability is called plasticity.

New genetic evidence points to novel therapies for “silent” stroke

According to a study, researchers have discovered new genetic clues in individuals who had experienced small but often apparently “silent” strokes.

Nutritional supplement may reduce the risk of strokes caused by a rare genetic disorder

Researchers from Children's Hospital of Philadelphia (CHOP) have discovered that a widely used nutritional supplement may significantly reduce the risk of fatal strokes caused by a rare genetic disorder.

Processed meat consumption associated with increased risk of dementia

Scientists from the University of Leeds's Nutritional Epidemiology Group used data from 500,000 people, discovering that consuming a 25g serving of processed meat a day, the equivalent to one rasher of bacon, is associated with a 44% increased risk of developing the disease.

Comprehensive mutation map helps better understand the biological processes underlying Alzheimer's

A study published in the journal eLife made all the possible mutations in the amyloid beta peptide and tested how they influence its aggregation into plaques, a pathological hallmark of Alzheimer's disease.

Two new Alzheimer’s genes discovered

AZoLifeSciences speaks to researchers from Tianjin Medical University about their latest research that led to the discovery of two new genes that are linked to Alzheimer's disease.

New signaling pathway prevents the overproduction of RNA-protein complexes

Neurodegenerative diseases, such as various forms of senile dementia or amyotrophic lateral sclerosis (ALS), have one thing in common: large amounts of certain RNA-protein complexes (snRNPs) are produced and deposited in the nerve cells of those affected - and this hinders the function of the cells.

Neuronal and glial circuits form loosely coupled super-network within the brain

Tohoku University scientists have shown that neuronal and glial circuits form a loosely coupled super-network within the brain.

First-in-human clinical trial to test safety, efficacy of gene therapy for Alzheimer's disease

Researchers at University of California San Diego School of Medicine have launched a first-in-human Phase I clinical trial to assess the safety and efficacy of a gene therapy to deliver a key protein into the brains of persons with Alzheimer's disease (AD) or Mild Cognitive Impairment (MCI), a condition that often precedes full-blown dementia.

Ancestral backgrounds can influence Alzheimer's disease risk, finds study

Genetics contributes to the risk of developing Alzheimer's disease, and the APOE gene is the strongest genetic risk factor, specifically the APOE4 allele.

TBI: Increased levels of immune cells promote inflammation that may worsen brain damage

Immediately after a traumatic brain injury and as long as one year later, there are increased levels of immune cells called ILCs in the brain promoting inflammation, which can worsen brain damage, scientists report.

Researchers discover genetic risk factor for stroke

A research team from Geisinger Health System has detected a common genetic variant as a risk factor for stroke, particularly in patients aged more than 65.

Study shows how AFV3-109 protein with slipknot structure folds and unfolds based on temperature

Scientists from the Pacific Quantum Center of Far Eastern Federal University (FEFU) figured out how the AFV3-109 protein with slipknot structure folds and unfolds depending on temperature. The protein is typical for the viruses of the oldest single-celled organisms that can survive in the extreme conditions of underwater volcanic sources - archaea. The research outcome appears in PLOS ONE.

KAIST researchers identify mechanism underlying plasticity in adult brains

Developing brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections — the ones that are repeatedly introduced, such as how to avoid danger — are nurtured and reinforced, while connections deemed unnecessary are pruned away.

Anti-diarrhea drug could be used to induce cell death in glioblastoma cell lines

The research group led by Dr Sjoerd van Wijk from the Institute of Experimental Cancer Research in Paediatrics at Goethe University already two years ago found evidence indicating that the anti-diarrhea drug loperamide could be used to induce cell death in glioblastoma cell lines.

New model shows how the brain uses "gating" phenomenon to control information

Getting computers to "think" like humans is the holy grail of artificial intelligence, but human brains turn out to be tough acts to follow. T
