Examples, what are the negative consequences associated with mental illness? Do these people live as long? Are they more likely to be in prison? To drop out of school? To be unemployed? Divorced? How does it impact their friends and family? What are the costs to society etc.
Please do not select one specific mental illness to talk about. You can talk about the connection between mental illness and criminal as my research question. You can use the movie “Joker” as one of your example in the essay.
