Dementia digital biomarkers & neurotech

Alzheimer's disease (AD), which accounts for 60% of the dementia population and mostly affecting people over 65 years old, though 5% of people with Alzheimer's are often younger than the above mentioned;
Vascular dementia, which occurs when blood vessels in the brain are damaged, reducing blood flow to brain cells, and it affects about 20% of the dementia population;
Dementia with Lewy bodies, which affects about 10-15% of the dementia population (Lewy bodies are small round clumps of protein that build up inside nerve cells);
Frontotemporal dementia, which primarily affects people aged between 45 and 64, accounts for fewer than 5% of dementia cases - symptoms may include changes in personality, memory loss, confusion and difficulty with day-to-day tasks.
