“From Active to Apathetic” (Current Psychiatry, February 2005) reports the decline of a 66-year-old man’s cognitive function as “sudden.”
If the decline was truly sudden, Drs. Rehan Aziz and Rajesh Tampi should have listed many more differential diagnoses than they did. At least major depression or so-called pseudodementia should have been included.
Except for apparent dementia related to some gross organic cerebral lesions, most of the dementias listed in the article would not suggest a pathological process deemed as sudden.

Dr. Tampi responds
Dr. Liu makes a very good observation that depression should be among the differential diagnoses for early dementia. We did not consider depression in our patient because:
- Decline was not ‘sudden,’ although the headline used that word. The changes in cognitive functioning, behaviors, and activities of daily living were unfolding for more than a year before the family brought him to our clinic for evaluation. His cognitive deficits were also severe enough to be in the moderate range for a dementia.
- The patient’s flat affect and lack of initiative were consistent with a frontal executive dysfunction as there was no subjective report of depressive symptoms. Also, family members noticed no neurovegetative depressive symptoms.
- The patient was started on bupropion and then was switched to citalopram. Neither medication resolved his apathy.
We included only the most common differential diagnoses for frontotemporal dementia. Including other neurodegenerative conditions would have made our case review very long and confusing.
