Can air pollution cause Alzheimer’s? Study finds toxins' hazardous effects

The study observed how exposure to toxins and inflammation can lead to S-nitrosylation that can disrupt healthy brain function, leading to brain disorders.

S-nitrosylation, usually triggered by inflammation, aging and exposure to toxins, can lead to disruption of brain cells. (Shutterstock)

Blood test shows promise for early detection of dementia: Study

Idiopathic REM sleep behaviour disorder is associated with a very high risk of Parkinson's disease and a related condition called Dementia with Lewy Bodies.

A blood test, originally developed to detect Alzheimer's disease, could also identify which patients with the iRBD sleep disorder are most likely to develop Dementia with Lewy Bodies. (Unsplash)

Key protein identified for treating Alzheimer's disease: Study

In Alzheimer's disease, certain proteins accumulate in brain cells, forming clumps that restrict normal cell function or even cause the cell to die.

A specific variant of the tau protein, known as the 1N4R isoform, mediates the harmful effects of protein clumping in human brain cells.(Unsplash)

Brain trauma can trigger Alzheimer's disease: Study explains

The findings suggest that vascular dysfunction could be an early driver in neurodegenerative disorders rather than being caused by neuronal damage.

While ageing leads to functional changes in the vasculature, brain trauma may exacerbate and accelerate these processes even in younger patients.(Pexels)
