Comments on: Much Less Than Half a Chance? Part 1 A revolution in time.

That number needed a ~ and a decimal point (now added). I apologize for the errors. I will probably find many more typos and (hopefully only) minor errors. No matter how many times I proof the text, I invariably find errors every time I read over it again. Since I am dysnumeric, I tend to reverse numbers, drop or misplace decimal places and even plug in completely erroneous numbers. I do check and recheck numbers, but the problem is I cannot see the errors.

So, I really do appreciate corrections!

One thing I would point out is that the ~3.2% number for BDDs included some cases of sudden, catastrophic brain CVD. For this preliminary version of the paper, I did not take the time to define the criteria I used for selecting that number, but I believe it is low, and should probably be revised upwards – I just don’t have the time to run that data to ground right now. Those data probably merit a separate breakout along with their inclusion criteria, although the absolute number is likely to be small compared to AD and the other “chronic degenerative” dementias. — Mike Darwin

Do you actually mean that dementias account for 32.3% of all deaths in the USA? This seems in conflict with the referred source PDF.

The PDF says:
“The 15 leading causes of death in 2008 accounted for 81.0 percent of all deaths in the United States (Tables B and 9). Causes of death are ranked according to the number of deaths; for ranking procedures, see ‘‘Technical Notes.’’ By rank, the 15 leading causes in 2008 were:
1. Diseases of heart (heart disease)
2. Malignant neoplasms (cancer)
3. Chronic lower respiratory diseases
4. Cerebrovascular diseases (stroke)
5. Accidents (unintentional injuries)
6. Alzheimer’s disease

… With Alzheimer’s disease accounting for roughly half of all dementias (people alive with the diagnosis, not of deaths?), the above list would exceed already 90% if we take 15% for each.
