Biology - accessing/treating brain

?
If apart of brain is damaged, how can we tell which part it is from the patient?
effects on the patient can determine where brain is damaged because different areas of brain controls certain things (e.g if patient's vision is wrong, there could be something from with area of brain that control vision)

Why is it hard to treat disorders in brain?
brain is complex (carrier between blood and brain that only let certain substances through - hard to drugs to reach. Also we don't fully understand brain yet) and delicate (easily damaged - hard to reach certain areas without damaging others)
