The y-axis is labeled "Number of Publications" so I have to assume it's showing the number of papers written on each malady over the years, though I'm not sure how the number sometimes goes down. You'd expect the numbers to steadily rise over time, depending on funding/interest.
The aging population could account for some of the rise in the past few years.
