Does this explain “the smell”?

“While the smell has been described as stale, medicinal, musty or simply "old person," the Japanese have developed a more elegant term: kareishu. In one study, Japanese researchers traced the odor to a chemical compound called 2-nonenal. The compound is a byproduct of other chemical breakdowns and emits a "greasy" or "grassy" odor as the molecules exit the skin and are released into the air. Researchers discovered that 2-nonenal was the only odor compound whose presence became stronger with age.”

It sounds like there might be other "chemical scents" involved in PD also :

Interesting, thanks. I wonder how and why the different compounds are produced.

Being different areas of the world, perhaps native diet is a factor too.

isn't it an interesting twist that the disease that has rendered my sense of taste and smell useless is responsible in part for my own "old man smell".
