The Ohio chapter of the National Alliance on Mental Illness says the disease is a biological brain disorder no different than other physical ailments.
The Sandusky Register reported Friday that the group asked Cedar Point amusement park to drop the displays because they promote false stereotypes.
The group says no one would ever try to use cancer in a similar attraction to scare people.
The displays are titled “Dr. D. Menteds Asylum for the Criminally Insane” and “The Edge of Madness: Still Crazy.”
