Figure 8

Distribution of post-diagnosis lifespan in ad/dementia (months). The figure presents the distribution of months after the diagnosis when individuals diagnosed with AD/dementia passed away. Among the individuals with available data in the dataset, 49.16% of those diagnosed with AD and 46.53% of those diagnosed with dementia had passed away as of February 2023. As evident from the figure, individuals with AD/dementia diagnoses who have passed away are predominantly within a close time frame to the diagnosis. In fact, 41.43% of those diagnosed with AD and 39.51% of those diagnosed with dementia had passed away within 12 months after diagnosis. This is supported by the negative correlation calculated at the level of (-0.7) between the total months survived post-diagnosis and AD, and (-0.77) between dementia. In other words, a decrease in the total months survived is observed among individuals diagnosed with AD.
