No, Roscoe is not technically mentally disabled. He falls into that category psychologists used to call "Dull Normal." IQ right around 80. Not quite normal intelligence, but not significantly impaired to qualify for government assistance or special consideration. Prognosis: Some possibility for independent living, but will need assistance in some areas, e.g., Doctor appointments, housekeeping, etc... Career options will include grocery cart chasing, NFL punt catching.
