Yes, there is a difference between the terms "mental disorder" and "illness," and it's essential to understand the distinctions, especially when talking about sensitive topics like depression and anxiety.
Mental Disorder: "Mental disorder" is a broader term used to describe various conditions that affect a person's thoughts, emotions, behavior, and overall mental well-being. It encompasses a wide range of conditions, including anxiety disorders, mood disorders (like depression), schizophrenia, personality disorders, and more. The term "mental disorder" is commonly used in professional and medical contexts to classify and diagnose these conditions based on recognized criteria.
Illness: "Illness" is a more general term used to describe a state of being unwell, diseased, or in poor health. It applies to both physical and mental health conditions. When used to refer to mental health, "mental illness" acknowledges that certain mental conditions can be considered illnesses that require attention, care, and treatment, just like physical illnesses.
The reason your sibling might have gotten upset with you is that some people prefer the term "mental illness" because it emphasizes the medical nature of their condition, while others prefer "mental disorder" because it doesn't carry the same negative connotations associated with the word "illness." Some individuals with mental health conditions feel that the term "illness" can be stigmatizing or make them feel like they are defined by their condition.
It's crucial to be sensitive and respectful when discussing mental health topics, especially with someone who has a personal experience with mental health issues. If your sibling prefers a specific term to describe their condition, it's best to use that term when addressing their mental health concerns. Remember that everyone's preferences and experiences are different, and open communication and empathy are key in supporting your sibling through their struggles with depression and anxiety.
