Depression as an intellectual discapacity?

>If thats the case, sheep would be the most intelligent species on earth

Not at all. Just commenting on how intelligence leads to depression. Makes it seem like there are fundamental limits on intelligence after a certain level.

>Makes it seem like there are fundamental limits on intelligence after a certain level.
I don't really think so. I think that most genes linked to intelligence must also be linked with depression. But there is a few who aren't. There are lots of genius who were pretty happy with their lives. Einstein or Feynman are examples of that.

not this wankery nonsense again

Actually the medical definitions band ways of treatment and diagnosis of disease are just as difficult or inconsistent as in psychiatry. The major difference is that there has been a microscopic technological revolution in biology. We do not have such technology in psychiatry. I guess psychiatry is like early medicine. Neither medicine or psychiatry are strictly sciences I'd say. I think the labels used can and often are uneven though I think that's more to do with difficulty in diagnosis.

Its a mood disorder and has little to no impact on intellect

I feel a lot of it is just stereotype. I feel people didn't hear about it from papers and probably don't have any.

I've actually seen papers where schizophrenia is linked to lower intelligence and higher intelligence is actually protective against schizophrenia unlike some stereotypes suggest. Wouldn't be surprised if same with any other mental illness.

People associate art and mental illness too but it's probably not mentally I'll people being especially creative (e.g. genetically). I
Havent read about it desu but shouldny just accept stereotypes without thinking
maybe just mental illness makes good material/ inspirations out of struggle.

A while ago I was read that depression was evolutionarily advantageous as in times of hardship it is better to keep your head down and expend less energy. Extrapolating from this, suicide could be explained as killing yourself cpuld be benifitial to the species during hardship as you wouldnt be consuming others resources, populations adjusting themselves for scarcity.

I don't buy those evolutionary explanations. In no way does a behaviour need to have survival value to exist. Those explanations are all ad hoc and purely speculative.

It's a matter of semantics in my opinion. Practicing medicine or being a doctor is honestly an applied branch of biology. That 'branch of biology' is the Medical Sciences which is very much a science.
Medical Sciences is broad in it's focus, but narrow in it's application. We can say this because MedSci takes things like chemistry, physics, biology and pretty much distills them regarding their application to human and animals. This can be elaborated further.

Psychiatry is a field of MedSci and Med. The reason for this is mostly thanks to huge advancements in technology and Neuroscience (and genetics). One can even say that, at this point, psychiatry has almost become an applied neurology of sorts.

This has allowed psychiatry to understand why and how particular psychiatric conditions behave and come about, thus allowing Med practitioners to treat patients more effectively and even study these conditions in more detail.
