Objective:
Assess the contribution of structural and functional neuroimaging methods to the diagnosis of dementia.
Methods:
This was a retrospective chart and imaging review. Participants were 24 inpatient dementia cases from a general hospital-based, university medical psychiatry unit. Data from clinical charts and imaging results were reviewed.
Results:
Most common initial diagnoses were dementia NOS and vascular dementia (VD); most common discharge diagnoses were VD, Alzheimer's, Dementia NOS and dementia with Lewy bodies. Most diagnostic changes occurred following family meetings or SPECT/PET, with fewer changes after CT/MRI.
Conclusions:
Diagnostic steps that contributed the most to the final diagnosis were the family meeting and the functional neuroimaging evaluation.
