Yes. But. 
The chart doesn’t really capture the complexity of the overall problem - there's a lot of mental illness that's not hospitalized. In reality, many (or most) of us will experience cognitive decline if we are fortunate enough to live long lives. Toward the end, serious mental decline - often lasting 1-6 months, is more than common, but it isn’t factored into this chart or treated in the same way, as it is categorically differentiated from 'mental illness'. But it is. And it's hospitalized, but not 'categorized' as such.

The brain is annoyingly just another organ (with 'magic properties', yes, but is still limited to our physics), just like the heart or liver, subject to disease, inflammation, and aging. Yet we often overlook this because our subjective experience of reality feels so distinct. But time is the most finite resource any of us has. Subjectively speaking (subjective to our lifespan) it's even more finite than Bitcoin. So the only thing more 'hard' than hard money is hard time. See what I did there - circled back to the chart. :]
