Differential diagnoses

  1. Alzheimer disease: Memory impairment is the cardinal symptom of Alzheimer disease. It is typically insidious and affects memory of recent events (i.e., the ability to remember 3 words a few minutes after repeating them). Other cognitive domains are typically also affected, presenting in this case with impaired spatial orientation (i.e., getting lost), impaired orientation (to time in this case), and impaired attention (i.e., inability to spell a word backwards). This patient is also at higher risk of Alzheimer disease because of her age, sex, history of hypertension, and lack of exercise.
  2. Normal pressure hydrocephalus (NPH): The triad of normal pressure hydrocephalus consists of urinary incontinence, dementia, and gait impairment, and this patient does have the first two features. However, her lack of gait impairment makes this diagnosis less likely than Alzheimer disease.
  3. Pseudodementia: Depression can cause memory impairment (which is then called pseudodementia) among many other symptoms, some of which this patient has: fatigue, low mood, loss of interest, lack of energy, inability to concentrate, poor sleep, and poor appetite. However, depression symptoms can also be symptoms of Alzheimer disease, which is more likely in this case because the patient's forgetfulness pre-dates her depression symptoms. Moreover, the onset of pseudodementia is usually sudden, rather than insidious, as in this case.
