The Bingo Card Sign as an Early Symptom of Alzheimer's Disease

Alzheimer's disease (AD) is characterized pathologically by irreversible protein misfolding-induced neuronal loss, and clinically by progressive impairments in memory, judgment, decision making, literacy and numeracy. We report a patient referred to Memory Clinic with a single complaint, "reduced capacity to play bingo." We suggest that the capacity to successfully play bingo may afford clinical clues indicating an early symptom of dementia and inquiries about bingo participation may be a useful when assessing individuals for dementia. Bingo requires the use of multiple cognitive skills which are impaired by AD, including number recognition, letter recognition, short term memory and concentration. With the game of bingo steadily gaining in popularity it may become an easily utilized line of questioning to detect indications of dementia prior to the development of currently recognized clinical symptoms.
