Age of onset ranged from 34 to 74. Initial diagnoses included 15 bvFTD, 9 ALS, 1 FTD-ALS, 2 alcoholic dementia, 1 mild cognitive impairment, 1 psychosis/schizophrenia, and 1 atypical Alzheimer disease. The common presenting symptoms are behavioural (47%) and language (47%), followed by executive dysfunction (40%), affective changes (40%), motor weakness (33%), memory problems (30%), and extrapyramidal symptoms (10%). ALS increased to 50% of the subjects in longitudinal follow up, and had a negative impact on survival (2.8 yrs +/- 1.5 with ALS vs. 8.4 +/- 3.8 without ALS).Conclusions: While patients with FTD and ALS associated with C9ORF72 hexanucleotide expansion have a common molecular mechanism and typical pathology, their initial clinical presentations can be quite variable and may overlap with other clinical syndromes. Early recognition requires a high clinical acumen. Other genetic or environmental factors may influence the presentation of clinical phenotype.Supported by: Canadian Institutes of Health Research [operating grants #179009, #74580] and the Pacific Alzheimer Research Foundation [center grant C06-01].Disclosure: Dr. Hsiung has nothing to disclose.
