Would quite like to defend the psychiatry camp. I want to be a psychiatrist specialising in trauma/psychotherapy - but really I want to be working in the field of global mental health in post-conflict and emergency situations, within humanitarian organisations, dealing with refugees, survivors of violence/torture etc.
Why psychiatry for me? I think it's one of the few specialities that's really interdisciplinary. There's just so much scope for broadening your interests, in terms of research, theory and practice. It's true, there is a lot we don't know about the mind yet [because, duh, it's the most complex and important organ] but that just means the scope for pioneering genetics, neurology/psychosurgery, imaging, as well as pharmacology research is vast. Equally if you like humanities, anthropology, social science, law, or public health then mental health allows you to be flexible and have those at the heart of whatever career you want.
Equally, people never realise how large and diverse the speciality really is. There is a lot of mental illness, and therefore a lot of sub-specialties. Want to deal with psychopaths? Forensics. Interested in eating disorders? Child and adolescent. Interested in more of a social approach? Learning disabilities. Interested in more of a biomedical approach? Old age psychiatry. Interested in trauma and communication? Psychotherapy. Want to deal with psychiatric emergencies in a medical hospital? Liaison. Want to deal more with the community? Addictions. A bit of everything? General adult etc. I love that it's a speciality where you do need to try your best to juggle the biological, psychological, social and cultural contexts of a patient - since so much of their illness can come down to those spheres, especially the ones which aren't immediately tangible. Yes, we often don't have signs that we can palpate - but we still have examinations regardless, and not relying on investigations/examinations just means your clinical and communication skills need to be even stronger.
At the end of the day I just cannot help but be fascinated by psychiatric patients [especially those with psychoses]. By people who believe they are entire planets, who believe they can walk through walls, who believe that everyone else is an alien imposter. The human capacity to be just so weird never ceases to amaze me. There's a lot of misconceptions about the speciality, and that has a huge impact on why people don't like psychiatry so this is my bit in trying to change some of those stock cliche phrases often bandied about by people who don't know better. Happy to talk about psychiatry with anyone interested/want to know more.
