Image of the Week: Do you recognize this neurodegenerative disorder?

A 71-year-old male returns for his annual health exam with concerns over progressive memory deterioration. He reports feeling well but is unable to state what he did yesterday or name the current month. His daughter mentions that he frequently forgets to feed the dog and often prepares the same meal twice in one night. On exam, he is pleasant and cooperative but has difficulty following multistep instructions. Further testing—including the clock drawing above—emphasizes visuospatial and orientation impairments. His Mini-Mental State Examination score is 19/30. Investigations reveal nonspecific slow waves on EEG and functional imaging shows abnormal blood flow in the medial temporal and parietotemporal areas of the cortex. Learn more about this case, take the quiz, and join the conversation on Figure 1.
