Placebo Effects: Brain Cures w/o Chemical Substances?

[kenny1999]

I know that if some patients are given real medicine while other some are given sweets but not told, for those who get positive effect without real medicine are placebo.

However, for the rest of those who don't have positive effect (without real medicine). Does it mean that some of the individuals could respond positively to placebo AT ALL FOR ALL MEDICINE while the rest of them never respond positively to ANY MEDICINE?

For those who could respond positively to placebo, In my opinion, it means their brain could
cure them instead of using real chemical substances, is there any research or study on these types of patients to find out how their brains are different from the other?

The placebo effect relates to how someone reports their condition. By definition, placebos do not directly improve the underlying condition.
There are certainly times when the placebo effect can have a real benefit - for example by encouraging optimism the placebo effect may also encourage the patient to take better care of himself/herself.
In such cases, someone who isn't helped by that kind of encouragement in one case, may certainly be helped by encouragement in other cases.

No. Virtually everyone responds to some medication and virtually everyone has some sort of placebo effect, especially given that certain things like pain are known to be somewhat controllable by one's mindset in some situations.

Probably, but given the extreme complexity of the brain I'd bet that there is unlikely to be any clear, noticeable, unambiguous differences that could account for someone's susceptibility to experience a placebo effect.
