FAQs
What are some less stigmatizing alternatives to "mental illness"?
Consider using terms like "mental health condition", "psychological disorder", or "emotional wellbeing challenge" to reduce stigma and promote a more positive perspective.
How can I use the term "mental illness" in a sentence respectfully?
Frame your sentences to focus on the individual's experience rather than labeling them. For example, instead of "He is mentally ill", say "He is living with a mental illness" or "He is experiencing symptoms of a mental health condition".
What's the difference between "mental illness" and "mental health"?
"Mental health" refers to overall psychological wellbeing, while "mental illness" describes specific diagnosable conditions that affect a person's thinking, feeling, or behavior. Good mental health does not preclude the possibility of experiencing a mental illness at some point.
Is it appropriate to use "mental illness" to describe everyday stress or anxiety?
No, using "mental illness" to describe everyday stress or anxiety trivializes the experiences of people living with diagnosed mental health conditions. It's important to distinguish between temporary stress and persistent, impairing symptoms of a mental illness.
