Ed Gein, a notorious American criminal and murderer, has often been described in various ways regarding his mental state. While "retarded" is an outdated and offensive term, modern assessments suggest that Gein likely had some mental health issues or cognitive impairments, but there is no clear or consensus diagnosis of intellectual disability. His bizarre behavior and crimes have been linked more to severe psychological disorders, such as psychosis or schizophrenia, rather than just intellectual impairment.
