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 […]

Cultivating joy through mindfulness: An antidote to opioid misuse, the disease of despair

November 4, 2019

New research shows that a specific mind-body therapy, Mindfulness-Oriented Recovery Enhancement (MORE), increases the brain’s response to natural, healthy rewards while also decreasing the brain’s response to opioid-related cues. The study, published Wednesday in the journal Science Advances, examined data from four experiments involving 135 adults who took opioids daily for chronic pain. The study […]

Study of twins shows what’s good for the heart is good for the brain

November 4, 2019

Emory University researchers are giving us double the reasons to pay attention to our cardiovascular health – showing in a recently published study in the Journal of Alzheimer’s Disease that good heart health can equal good brain health. The American Heart Association defines ideal cardiovascular health (CVH) across seven modifiable risk factors (blood sugar, serum […]

Projected doubling of Americans living with dementia

October 30, 2019

The number of Americans living with Alzheimer’s disease or other dementias will double to nearly 13 million over the next 20 years, according to the new Milken Institute report Reducing the Cost and Risk of Dementia: Recommendations to Improve Brain Health and Decrease Disparities. Milken Institute research estimates that by 2020, roughly 4.7 million women […]

Blood-brain barrier damage occurs even with mild head trauma

October 3, 2019

In a new study of adolescent and adult athletes, researchers at Ben-Gurion University of the Negev, Stanford University and Trinity College in Dublin have found evidence of damage to the brain’s protective barrier, without a reported concussion. For the first time, the researchers were able to detect damage to the blood-brain barrier (BBB), which protects […]

Key to Learning and Forgetting Identified in Sleeping Brain

October 3, 2019

Distinct patterns of electrical activity in the sleeping brain may influence whether we remember or forget what we learned the previous day, according to a new study by UC San Francisco researchers. The scientists were able to influence how well rats learned a new skill by tweaking these brainwaves while animals slept, suggesting potential future […]
