It deals with the study of behavioral and cognitive disorders. That means, it studies behavioral traits that are seen as undesired, therefore deemed disordered. This of course means that any behavioral trait can become a disorder as soon as society considers it undesired. Also explaining why homosexuality is not a mental disorder anymore, whereas ADHD or the unruly kid in your school is now mentally defective because of society's expectation that one ought to pay attention to authorities and conform to a repetitive routine.
Depending on the philosophical or political approach, psychiatry will use different approaches when it comes to treating psychiatric disorders. Earlier by force and segregation, nowadays by forceful drugging.
Psychiatry is what Medicine would be if you replace the body with society. It deals with isolating the pathological members of society that cause "harm" or are non-productive similar to how medicine would treat tumors or warts. Clearly, there's absolutely no room for tremendous abuse there.
