Metabolic Patterns of 18 F-FDG in Dementia

Dementia syndromes are a leading cause of morbidity and mortality in the elderly population. Unfortunately, there are limited treatment options, especially in advanced cases. This creates a diagnostic dilemma, as the dementia syndromes often overlap in clinical presentation early in the disease process. 18F-FDG has been utilized to help differentiate between the various causes of dementia based upon differing areas of altered brain metabolism, allowing for an appropriate treatment regimen to be initiated.
