Clinical decisions made with and without the input of CT were compared. The study was based in an outpatient referral centre for the assessment of memory disorders and dementia. The study involved 146 participants who were diagnosed with dementia after their first clinic visit, had Mini Mental State Examination scores &gt;12, were aged &gt;65 years, and had no history of neurologic disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>CT impacted on diagnosis in an average of 12% (\u00b12), and on treatment plan in 11% (\u00b12) of cases.
