Frontotemporal lobar degeneration: diagnosis and epidemiology in a Colombian memory clinic through thirteen years (1997-2010)

Frontotemporal Dementia (FTLD) is a progressive neurodegenerative disease affecting behavior and language. With an early onset, its clinical presentation is highly heterogeneous and though its neuropathology, once thought mainly to be a tauopathy, has become increasingly complex.
