Abstract

Frontotemporal dementia is increasingly recognised as an important cause of early-onset dementia and is considered to be the second commonest neurodegenerative dementia after Alzheimer's disease. We describe the cognitive, behavioural profile and neuroimaging characteristics of 6 patients with frontal variant of Frontotemporal dementia that were evaluated at the cognitive behavioural clinic at this tertiary referral teaching hospital. All patients underwent clinical, neuropsychological, structural/functional neuroimaging, and laboratory evaluations. The male to female ratio was 1:1; mean age of onset was 54 years, and the mean duration of symptoms were 30 months. The mean scores for Addenbrooke's cognitive examination, Frontal Assessment Battery, and Mini-Mental State Examination were 70.5, 6.33 and 23.6 respectively. The mean VLOM ratio was 2.04. MRI revealed significant asymmetrical regional frontal/temporal atrophy supplemented by the evidence of circumscribed hypoperfusion in SPECT imaging. We conclude that a combination of behavioural and cognitive assessment using short bedside tests, along with structural and functional neuroimaging does facilitate early identification, and increase the diagnostic specificity of Frontotemporal dementia.
