Who is affected by Cushing syndrome? The people most commonly affected by Cushing syndrome are children, teenagers and adults, mostly those ages 25 to 50. People who take cortisol medication (for example, to treat asthma and rheumatoid arthritis) are especially vulnerable. Some 70% of people with Cushing syndrome are women or people assigned female at birth (AFAB) and 30% are men or people assigned male at birth (AMAB).

Mental illness also seems to affect people who write about Cushing's Syndrome.

My dad was diagnosed with cushing's in the 70s. It was really rare then. He was one of six or seven patients and the only male across the US that his endocrinologist was treating. He developed it while in Vietnam so I tend to suspect it was AO or other pesticides and chemicals being used then. Today it is much, much more common. Again i think chemicals (food additives and enviromental) are causing havoc. I was very young when my dad had it (corrected by surgery) so I don't remember any odd behavior nor do I recall any talk of it. That woman is beyond erratic and bizarre. I would be very, very surprised to find out drugs weren't involved as well.
