If syphilis is disappeared untreated How long will it appropriate to budge insane?

It takes pretty long- I expect on the order of 10-20 years contained by most cases, although some can rapidly progress within as quickly as 3 years.
Once syphilis cause neurological symptoms, they generally aren't reversible even if the bug is kill. A quick shot of penicillin can filch care of it long back it gets to that point.
Theres 4 stages. I know the first stage is treatable, the ultimate stage is death.
