Cataract Surgery: One Operation, Many Benefits?

Researchers at Tenon Hospital in Paris found that people with mild forms of Alzheimer's disease saw an improvement in sleep patterns, cognitive functioning and mood after undergoing vision-correcting cataract surgery.

The researchers aren't sure what led to the positive effects, but hope to find answers through future studies.
