Longevity & AgingNew Digital Tool Detects Memory Decline Years Before Symptoms Appear
A London health tech startup called Prema Cognition has raised $730,000 to expand PREMAZ, a digital cognitive assessment built with the University of Cambridge Memory Lab. Unlike standard memory tests that only flag problems after noticeable decline, PREMAZ measures subtle shifts in how precisely the brain stores and retrieves information — potentially catching early Alzheimer's warning signs years sooner. The tool is already deployed across 30-plus clinics in the UK and US. Early detection matters increasingly because newer Alzheimer's therapies appear most effective at the earliest disease stages, before irreversible brain damage occurs. The round was oversubscribed, drawing investors from biotech, pharma, and longevity healthcare, signaling growing conviction that cognitive health is central to the future of aging medicine.
