PPA, a language disorder that mostly affects men

Post Reply New Topic

I read and interesting article about Primary Progressive Aphasia, a progressive language disorder that mostly affects men. A recent study found that men who have vasectomies might have a greater risk of developing PPA.

Now I'm wondering if there is a relationship between autism and Primary Progressive Aphasia?

Autism also affects more males and females, it also affects language. One idea is that autism is caused by several genes interacting with elevated pre-natal testosterone levels, the higher the testosterone the greater the risk of developing autism.

I have not read the PPA study yet, but I'd be interested to hear if a vasectomy causes testosterone levels to change drastically, I'd expect an increase. Elevated testosterone might decrease men’s ability to cope with PPD, the disease progresses faster and is more pronounced. Or there are misdiagnoses happening, male Aspies wrongly diagnosed with PPA? Or some male Aspies develop a language disorder in later life that is mistaken for PPA?

Any thoughts?

I didn't have a vasectomy. My father didn't EITHER! HECK, for quite some time after my birth, vasectomies were considered IRREVERSIBLE! So really NOBODY in my generation could have been affected by that. WHY would it increase testosterone? They have always said there is NO change!

My symptoms in part were the REVERSE of dementia. The silly theories some come up with! MAN! ALSO,PPA would make an AS diagnosis LESS likely, not more so.
