Figure 2

Prevalence of total pre and post diseases among individuals diagnosed with ad and dementia. Figure 2 consists of four different graphical representations. Graphs "1" and "3" present the distribution of the total number of pre and post diseases in individuals diagnosed with AD. According to this, individuals diagnosed with AD have a prevalence of 64% for having 2–5 pre-diseases, while 47% of them have no post-diseases, and only 30% have 1 post-disease. Information related to individuals diagnosed with dementia is presented in representations "2" and "4." From these representations, it can be observed that individuals diagnosed with dementia have a prevalence of 66% for having 2–5 pre-diseases. The prevalence of post-disease among individuals with dementia is 42% for having none and 30% for having 1 post-disease. As a summary of these four graphical representations, the prevalence of experiencing different diseases before the AD/dementia condition is high.
