Figure 3

Time of onset of pre-diseases before AD/dementia diagnosis (Months). The visual labeled as "1" represents the distribution of pre-diseases just before AD, while the visual labeled as "2" shows the distribution for individuals diagnosed with dementia. As can be seen from the figure, the diseases that occur just before receiving an AD/dementia diagnosis are organ failures and cerebrovascular events. Hypertension, on the other hand, appears approximately 3 years before the diagnosis. Additionally, the year just before the AD/dementia diagnosis is a period with a high likelihood of developing pre-diseases.
