Pick's disease ...

There is a website called "The Painter's Keys" that was run by an artist who died a few years ago leaving a huge amount of material. I used to read the letters twice weekly and often contributed to the site. I also have a collection of letters and comments that was sent to frequent contributors as a gift. Looking for something quite different under my artist name (FP), I came across this comment here: https://painterskeys.com/creative-muscle/. This is the entry copied exactly including one or two errors I obviously did not see at the time.
I don't subscribe to that website now. It lost its charm for me when his daughter took over.

Pick’s disease and art

PPA is a most intriguing subject. How many of your readers and contributors are going to start looking for signs of what is called Pick’s disease in some circles and has a number of other names: “Primary progressive aphasia; Aphasia — primary progressive; Semantic dementia; Dementia — semantic; Frontotemporal dementia; Arnold Pick’s disease”? It has always intrigued me that scientists insist that every brain has the same pattern of functions, even though not everyone is e.g. right-handed. What if the talented artist has different brain patterns from the word go? We need never know what is going on in our brains, unless some striking change in “activity” is classed as a medical condition. Autistic children are born autistic and presumably also born savants, though at birth they have never seen a piano or held a pencil. Brains presumably do not all function in the same way, so what’s to stop a congenitally different brain-layout and functioning contributing to someone being an artist of some kind? I instantly went around the Web looking for more information on this. In this article by Benedict Carey two artists who suffered from Pick’s disease are compared. The message seems to be: As long as the effects are not debilitating, it’s not such a bad idea. Unfortunately, we cannot choose which disorder we contract. Is Pick’s disease wasted on non-artists, then? I find it really uncanny that Anne Adams hit on Ravel, who died of the same disease. Birds of a feather.
