Neurologist Flags 2 Sensory Loss Risks for Dementia as Study Says Nearly Half of Cases May Be Preventable

Summary
Dr. Kellyann Niotis said vision and hearing loss are often-overlooked dementia risk factors and urged people to stay current on annual eye and hearing screenings.
A 2024 Lancet study found nearly half of dementia cases worldwide could potentially be prevented by addressing modifiable risks, including sensory loss.
Niotis said the link may reflect reduced brain stimulation and knock-on effects such as less social engagement and exercise when sight or hearing deteriorates.
Warning signs include halos, color changes and words seeming to jump on the page for vision, while hearing loss is often first noticed by friends or family.
She pointed to practical prevention steps—ear protection around loud noise, sunglasses and less direct UV exposure, plus screen breaks that can also support brain-healthy activity.
