  • This number is expected to increase to 536,164 by 2025 [1]
  • Without a medical breakthrough the number of people with dementia is expected to reach 1,100,890 by 2056 [1]

  • On average symptoms of dementia are noticed by families three years before a firm diagnosis is made *

* The time between onset of dementia symptoms and diagnosis is often prolonged, leading to years of uncertainty for patients and their families. Research has shown that the average time from first symptoms to diagnosis, - as reported by informants/family - is between 1 and 3 years with symptoms recorded in general practitioners’ medical records as early as 5 years before diagnosis
