Cause di Disforia di Genere

We don't know enough about the brain to make definite statements, except to say that at the moment, substantial evidence is absent, etc. If GID can only happen in adulthood, that doesn't add up with evidence considering how most transsexual people identified with their brain-gender well before adulthood.

Since my earliest memories I felt something was wrong. I felt like a freak from my childhood to an adult. I had to fake things that did not feel natural to me so I could blend in the best I could. You spend most of your life acting a part and otherwise I felt like I would not be accepted by my peers or my family. And you spend so much time acting and putting up walls that you forget why your doing it or who you are. I looked back on my life and I had many memories but in many ways it all felt like a fog. Even though I remember everything it felt like I was living some one ells's life. I could not make sense of why I felt that way. Back in 2013 my Dad past away and the walls I had put up started falling. Many memories I had stuffed away started coming back in a rush and realized why I spent so many years in depression and feeling miserable. At this point many would think I would go off and get HRT and get surgery, but no. I am one of the few that has elected not to because I can't stand the thought of losing everyone I love. And there are other reasons but many would not understand those. The reason why I commented is because its not something that comes about when you are an adult, you suffer from it your whole life. And I hate it when people that do not understand what a person like I and others like me go through talk about it as though they were an authority on my life. I have lived it, you have not and so can not begin to talk about what you do not know. I am not trying to be an ass but you have no idea what me and others have gone through our whole lives(not just adulthood). It is miserable existence, acting out a life that is not you at all. You realize that no one you know truly knows you but only the part you play. Like I said I love my family and even though they don't know me I know enough about them that I want to keep them in my life so I am one of the few that has chosen to remain silent, but your not family so I have no problem telling you.

Most transgender children know their true gender by age two, according to my doctors and multiple documentaries I've seen. I knew by at least age 5 and it was a huge issue for me my entire life, especially during grade school through high school. It has caused numerous health problems in my adult life because I didn't have the support and correct info. that I needed. The American Psychiatric Association no longer considers being transgender or transexual a mental disorder or illness.

Another Christian bigot promoting faux science by the other Chrisitan bigot named "Dr McHugh" who has been discredited by all medical and psychological consensus? I find it fascinating how trolls so suspiciously interested in this subject seem to crawl their way to every legitimate scientific journal/research in order to disseminate false information on the subject.
Seek help from a qualified psychologist because your well known behavior is pathological

As a transgender person I know this to be true. Transsexualism is an inter-sex condition of the the brain. I recently saw a wonderful documentary confirming this. Thank you for your post.

Catchable you mean as in, contagious?  Lou Gehrig's disease or MS isn't "catchable" neither but they are still diseases.

The main point of replacing "gender identity disorder" with gender dysphoria in the DSM-5 was to end the very type of stigma expressed in your comment. Nowhere in the DSM-5 does is say that gender nonconformity is a disease or mental illness. Gender dysphoria refers to the significant stress caused by the discrepancy between one's gender assigned at birth and the gender to which that person identifies. When the level of stress is significant enough to impair normal social and emotional functioning, a diagnosis of gender dysphoria is suitable. Science has yet to produce definitive evidence as to the cause (if any exist) so to declare GD as a choice is pure conjecture and should be dismissed as such.

I have heard of children who have gender dysphoria as a result of parents saying "I wish you were a (opposite sex)."  Things that happen while in the parents womb can impact a child - so if your mum talked to you as a girl etc it is possible that this caused gender dysphoria.
