An Aspirin a Day Does Not Keep Dementia at Bay

April 9, 2020

Taking a low-dose aspirin once a day does not reduce the risk of thinking and memory problems caused by mild cognitive impairment or probable Alzheimer’s disease, nor does it slow the rate of cognitive decline, according to a large study published in the medical journal of the American Academy of Neurology. Aspirin has anti-inflammatory properties […]

Alzheimer’s disease: Inflammation triggers fatal cycle

March 26, 2020

An immune reaction in the brain seems to play a major role in the development of Alzheimer’s disease. In a way, it “adds fuel to the fire” and apparently causes an inflammation that, in a sense, keeps kindling itself. The study has now been published in the journal Cell Reports. Alzheimer’s disease is characterized by […]

A good blood supply is good for memory

March 6, 2020

Memory performance and other cognitive abilities benefit from a good blood supply to the brain. This applies in particular to people affected by a condition known as “sporadic cerebral small vessel disease.” Researchers of the German Center for Neurodegenerative Diseases (DZNE) and the University Medicine Magdeburg report on this in the journal “BRAIN.” Their study […]

Could new discovery play a role in diagnosing Alzheimer’s earlier?

March 5, 2020

Scientists have detected that a previously overlooked gene behavior could potentially lead to a new way to diagnose Alzheimer’s earlier. Published in the journal Epigenetics, an international research team’s findings – discovered in mice and confirmed in human samples – suggest that the gene Presenilin1 (PSEN1) should be monitored as a ‘biomarker’: to see what […]

Empathy can be detected in people whose brains are at rest

February 20, 2020

UCLA researchers have found that it is possible to assess a person’s ability to feel empathy by studying their brain activity while they are resting rather than while they are engaged in specific tasks. Traditionally, empathy is assessed through the use of questionnaires and psychological assessments. The findings of this study offer an alternative to […]

Binaural beats synchronize brain activity, don’t affect mood

February 20, 2020

An auditory illusion thought to synchronize brain waves and alter mood is no more effective than other sounds, according to research in adults recently published in eNeuro. The effect reported in other studies might be a placebo but could still have helpful effects for some people. Binaural beats are an auditory illusion caused by listening […]

How the brain’s immune system could be harnessed to improve memory

February 14, 2020

Inflammation can send the brain’s immune cells into damaging hyperdrive, and this has been linked to neurodegenerative diseases that affect memory, like dementia. In the new study, researchers at RMIT found that these same immune cells – known as microglia – can also be activated to have the reverse effect. When the microglia were altered in rats, their performance in simple memory tasks improved by up to 50%, rather […]

Scientists develop non-invasive method to predict onset of dementia

February 14, 2020

Information gathered from routine visits to the doctor is enough to accurately predict a person’s risk of developing Alzheimer’s disease and related dementias, according to new research led by scientists from Regenstrief Institute, Indiana University and Merck. The researchers developed and tested machine learning algorithms using data from electronic medical records to identify patients who […]

Possible increased risk of dementia, Parkinson’s, Alzheimer’s and MS

January 25, 2020

Living near major roads or highways is linked to higher incidence of dementia, Parkinson’s disease, Alzheimer’s disease and multiple sclerosis (MS), suggests new research published recently in the journal Environmental Health. Researchers from the University of British Columbia analyzed data for 678,000 adults in Metro Vancouver. They found that living less than 50 metres from […]

The pathway to Parkinson’s takes a surprising twist

November 19, 2019

In neurodegenerative conditions like Parkinson’s disease, a specific group of neurons start to perish one by one, causing movement problems and other symptoms. Scientists have long focused on finding out why these neurons die. Now it turns out, they might not even be dead. Rockefeller researchers found that affected neurons in Parkinson’s disease can shut […]
