There are different types of problems; classifying them can help us address, research, analyze, and solve them. I have known people who've struggled with mood and focus. Knowing if it's caused by a disease (depression), circumstance (losing a loved one), or intentional behavior (playing video games when they should've been sleeping), helps determine what sort of treatment is likely to be effective. Medicating a person for a character flaw is just as dangerous as castigating them for a disease.
