Letter to the Editor May/June 1999

The article "SPECT May Help Resolve Dementia Diagnosis," in the January/February issue fails to mention EEG in diagnosis of dementia, a test cheaper than SPECT and CT. EEG is quite sensitive, correlates with prognosis, and is specific withing a given clinical context.

Your title "May Help Resolve" may generate unnecessary referrals for SPECT scanning in this situation. At a time of rigorous health care funding, we need to utilise only those tests which are clearly going to benefit the patient in a cost-effective manner. This article does not advance that goal.

Sincerely,

P.S. The cost of EEG versus SPECT scanning is $51.20 and $162.50 respectively.
