Methods: Clinical and pathological information was abstracted from histopathologically confirmed ALSP cases identified by a systematic literature search. A new case of ALSP presenting as bvFTD was also described. Results: We retrieved 51 ALSP cases. Mean age of onset was 42.2 years. Mean disease duration was 6.2 years, with 24 cases lasting 4 years or fewer. Fourteen cases had 3 or more of the 6 key bvFTD features. White matter hyperintensities on T2-weighted MRI, motor symptoms, seizures and amnesia were common. Conclusion: ALSP can underlie FTD syndrome, as well as rapidly progressive dementia. %I Karger Publishers
