The cross-sectional study examined 54 older adults diagnosed with or suspected of having mild cognitive impairment and disturbed sleep.

Participants taking at least 5,000 IU of vitamin D daily scored more than 13 percent higher on the Montreal Cognitive Assessment.

The study was small and observational, so it cannot establish whether vitamin D improves cognition.

The NIH recommends 600 IU daily for most adults and 800 IU from age 70; 5,000 IU should be discussed medically.

Findings suggest that taking higher doses of daily vitamin D supplementation is associated with better overall cognitive performance in this population.

Joel said last month that shunt surgery had improved his condition; he is currently undergoing physical therapy.

His medical team advised him to avoid live performances for now because of sound, lighting, exertion and touring stress.

Doctors advised him not to drive after the diagnosis; he is therefore selling 70 motorcycles from his collection.

Further tests will clarify a possible return; Joel and sources close to him say retirement is not planned.

I can’t drive right now. And I can’t do performances because what the neurologist told me, every time you do a show, it’s like you’re getting a concussion.
— Billy Joel told The Hollywood Reporter in a new interview, discussing his diagnosis of normal pressure hydrocephalus (NPH) and his temporary inability to perform.
