Can gut infection trigger Parkinson’s disease?

July 24, 2019

A new study by Montreal scientists published today in Nature demonstrates that a gut infection can lead to a pathology resembling Parkinson’s disease (PD) in a mouse model lacking a gene linked to the human disease. This discovery extends recent work by the same group suggesting that PD has a major immune component, providing new […]

Alzheimer’s missing link ID’d, answering what tips brain’s decline

July 24, 2019

Years before symptoms of Alzheimer’s disease appear, two kinds of damaging proteins silently collect in the brain: amyloid beta and tau. Clumps of amyloid accumulate first, but tau is particularly noxious. Wherever tangles of the tau protein appear, brain tissue dies, triggering the confusion and memory loss that are hallmarks of Alzheimer’s. Now, researchers at […]

Broccoli sprout compound may restore brain chemistry imbalance linked to schizophrenia

May 17, 2019

They say the results advance the hope that supplementing with broccoli sprout extract, which contains high levels of the chemical cruciferous vegetables, may someday provide a way to lower the doses of traditional antipsychotic medicines needed to manage schizophrenia symptoms, thus reducing unwanted side effects of the medicines. “It’s possible that future studies could show […]

Exercise activates memory neural networks in older adults

April 26, 2019

How quickly do we experience the benefits of exercise? A new University of Maryland study of healthy older adults shows that just one session of exercise increased activation in the brain circuits associated with memory — including the hippocampus — which shrinks with age and is the brain region attacked first in Alzheimer’s disease. “While […]

Important insight on the brain-body connection

April 22, 2019

A study conducted by University of Arkansas researchers reveals that neurons in the motor cortex of the brain exhibit an unexpected division of labor, a finding that could help scientists understand how the brain controls the body and provide insight on certain neurological disorders. The researchers studied the neurons in the motor cortex of rats […]

Early exposure to pesticides linked to small increased risk of autism spectrum disorder

April 7, 2019

Exposure to common agricultural pesticides before birth and in the first year of life is associated with a small to moderately increased risk of autism spectrum disorder (ASD) compared with infants of women without such exposure, finds a study published in The BMJ today. The researchers say their findings support efforts to prevent exposure to […]

Eyes reveal early Alzheimer’s disease

April 7, 2019

Reduced blood capillaries in the back of the eye may be a new, noninvasive way to diagnose early cognitive impairment, the precursor to Alzheimer’s disease in which individuals become forgetful, reports a newly published Northwestern Medicine study. Scientists detected these vascular changes in the human eye non-invasively, with an infrared camera and without the need […]

A nutty solution for improving brain health

March 25, 2019

Long-term, high nut consumption could be the key to better cognitive health in older people according to new research from the University of South Australia. In a study of 4822 Chinese adults aged 55+ years, researchers found that eating more than 10 grams of nuts a day was positively associated with better mental functioning, including […]

Does Food Impact Memory?

February 8, 2019

You may be familiar with the saying, “You are what you eat,” but did you know the food you eat could impact your memory? Auriel Willette, assistant professor, and his team of researchers in Iowa State University’s Department of Food Science and Human Nutrition discovered a satiety hormone that, at higher levels, could decrease a […]

This is how the brain forgets on purpose

September 13, 2018

Researchers from Ruhr-Universit?t Bochum and the University Hospital of Gie?en and Marburg, in collaboration with colleagues from Bonn, the Netherlands, and the UK, have analysed what happens in the brain when humans want to voluntarily forget something. They identified two areas of the brain — the prefrontal cortex and the hippocampus — whose activity patterns […]
