9. An 82-year-old woman is brought to the physician by her granddaughter because of a 6-week
history of increasing forgetfulness. She is a retired schoolteacher and lives independently. Her
granddaughter is concerned because on several occasions she has left the stove on when she went
to bed. During conversations with her granddaughter, she has difficulty remembering past events
and seems unconcerned about her memory lapses. The patient describes trouble sleeping through
the night and has had a decreased appetite resulting in a 4.5-kg (10-lb) weight loss over the past
month. She has a history of similar symptoms 2 and 5 years ago that were successfully treated with
medication. She appears unkempt and has poor personal hygiene. Her temperature is 37 C (98.6 F),

psychomotor retardation, a flat affect, impaired ability to recall past events, and trouble repeating
three numbers in sequence. She is unable to recall the names of recent presidents. Her serum urea
nitrogen (BUN) level is 25 mg/dL, and serum creatinine level is 1.7 mg/dL.
