Laser-Based Dementia Test Could Detect Disease Years Before Symptoms

Date: 03-apr-2025

Scientists in 2025 have developed a revolutionary laser test capable of diagnosing early-stage dementia within five minutes. This innovation marks a turning point in neurological healthcare, potentially enabling early intervention strategies before cognitive symptoms appear.

How It Works

The test uses low-level lasers to analyze the retina, detecting amyloid proteins associated with dementia. Unlike traditional brain scans, it is non-invasive, cost-effective, and can be administered at local clinics.

Implications for Global Healthcare

Detects dementia up to 10 years before symptoms
May reduce long-term healthcare costs and burden
Could become standard screening tool by 2027

Healthcare systems across the UK and Europe are already running pilot programs, with India and Japan expected to adopt the method next year.
