I am astonished to hear people say that PMDD is some sort of illness invented by the drug industry.
I agree. I have more than PMS...you can call it PMDD, severe PMS, crazy...whatever. It's as real as cancer in a patient. The thing is most cancer patients can be diagnosed and treated where as many people with PMS are still fighting for answers on how to treat the symptoms.
I personally feel that the 3-8% is a bit low for PMDD because it only makes sense that many women do not report their "craziness" to researchers/Doctors. For example, if a woman was complaining of having suicidal thoughts to her doctor, more times than not they will be thrown into a hospital pumped full of drugs and be diagnosed with major depression.
You hear on the news "She was a wonderful mother, loved her children...yet no one can explain why she killed them". A theory of mine is that the severe cases of PMS may have cause these incidents. I'm not saying that it is the only source but right now I'm working on a theory. Especially for those mothers that have done horrible crimes and has never been a trouble maker and had a reputation of being a "soccer mom"/perfect citizen.
