I have seen this myself. All of the testing and guidelines are set for how males represent so, of course females will slip through the cracks as they present differently. I have heard Drs state that females can not have ASD or ADHD because they don't fit the mold. There is only one mold, the male dx and women are diagnosed with BPD/EUPD instead because society expects females to socialize in a different and more involved way that we expect males to so any deviation must be a neuroses.  This is very frustrating when you see middle aged women who could have been accommodated and assisted who had Zero help and an improper dx. The Medical and Psychology fields need to swiftly and decisively address this.
