A searing pain around the eye and on one side of the head wakes up Niranjan on most nights. It lasts between 15 minutes to an hour and on some days returns after short periods of respite.

Enlarged fluid-filled spaces around cerebral small blood vessels were linked to cognitive decline, a prospective study of older adults showed.
Severe perivascular space pathology in both the basal ganglia and the centrum semiovale, or in the centrum semiovale alone, was tied to a greater drop in global cognition over 4 years, reported Matthew Paradise, MBChB, MSc, of the University of New South Wales in Sydney, Australia, and co-authors.
Large perivascular space dilation in both brain regions was an independent predictor of dementia across 8 years of follow-up (adjusted OR 2.91, 95% CI 1.43-5.95,
P=0.003), with stronger effects at either year 4 or 6, the researchers wrote in
Simple vision tests can predict Parkinson s dementia before it begins
Simple vision tests can predict which people with Parkinson s disease will develop cognitive impairment and possible dementia 18 months later, according to a new study by UCL researchers.
The study, published in
Movement Disorders, adds to evidence that vision changes precede the cognitive decline that occurs in many, but not all, people with Parkinson s.
In another new study published today in
Communications Biology, the same research team found that structural and functional connections of brain regions become decoupled throughout the entire brain in people with Parkinson s disease, particularly among people with vision problems.
