Migraines linked to higher risk of dementia

Dementia is the most common neurological disease in older adults, whereas headaches, including migraines, are the most common neurological disorder across all ages. In a recent study in the International Journal of Geriatric Psychiatry that included 679 community-dwelling adults aged 65 years and older, migraines were a significant risk factor…

Molecule reduces accumulation of toxic protein in Parkinson’s disease model: The discovery supports GM1 ganglioside as a potential target for Parkinson’s therapy

Parkinson’s disease often begins with small tremors. Over time symptoms worsen. Tremors become shakes and stiffness takes the body hostage. People with advanced stages of the neurodegenerative disease often have trouble with coordination, walking and maintaining their balance. Currently no cure exists for the condition and available treatments only address…

Scientists map toxic proteins linked to Alzheimer’s

A team of researchers from McMaster University has mapped at atomic resolution a toxic protein linked to Alzheimer’s disease, allowing them to better understand what is happening deep within the brain during the earliest stages of the disease. The findings, published on the front cover of the current edition of…

Long work hours associated with increased risk of stroke

People who worked long hours had a higher risk of stroke, especially if they worked those hours for 10 years or more, according to new research in the American Heart Association’s journal Stroke. Researchers reviewed data from CONSTANCES, a French population-based study group started in 2012, for information on age…

Astrocytes protect neurons from toxic buildup

Astrocytes are overtaxed neurons’ pit crew. The brain cells collect damaged lipids secreted by hyperactive neurons, then recycle those toxic molecules into energy, researchers at the Howard Hughes Medical Institute’s Janelia Research Campus report May 23, 2019, in the journal Cell. It’s a mechanism to protect neurons from the damaging…
