I have searched every nook of the internet and I couldn't find a clear and to-the-point answer. Well my story is that I am a young BSc student who wants to do research on neurological conditions because as far as my knowledge goes neurologists cannot do anything about ANYTHING, things like dementia and brain damage lead the person to become completely destroyed and then eventual death is what every doctor has to see. As of current.
So I am asking if we can develop eventually effective treatments for let's say OCD or Alzheimer's? Or that will never happen because of other factors in the ecosystem and it's the rule of the nature that some people are just unfit to survive? If that's possible, and about to happen in my life time -- i.e., I can contribute -- I am in. I am gonna get a doctorate in one of the life sciences and start doing something. Like discovering genes, or understanding the pathophysiology, or discovering drugs, whatever I am competent in and able to. I just cannot see people suffer like that.
