I know someone already talked about mental health, but I would just like to generalize this to overuse and misuse of all neurological diseases. Words like "OCD", "autistic", "Alzheimer's", "migraine", "psychopath", "Tourette's", and other terms are often used to describe individuals who do not have those conditions.
Misdiagnosis is, unfortunately, a common occurrence even in real life. Physicians who have spent eight years of their lives in school, working 80+ hours a week to learn how to diagnose neurological disorders are subject to misdiagnosis. Unfortunately, misdiagnosis and misinformation has perpetuated stigmas surrounding these disorders and caused real harm to real people who have them. If we, as authors, allow our media to be filled with even more misrepresentation, we are perpetuating those harmful stereotypes.
OCD doesn't mean someone who is clean.
Autistic doesn't mean someone who is socially awkward.
Alzheimer's doesn't mean any elderly person with memory impairment.
Tourette's doesn't mean someone who curses a lot.
Psychopath doesn't mean a mass murderer.
And, most close to my heart because of my career choices, migraine doesn't mean a bad headache.
Thanks for reading my rant.
