Frontotemporal lobar degeneration - Radiopaedia.org
WEBMay 6, 2024 · Frontotemporal lobar degeneration (FTLD) is the pathological description of a group of neurodegenerative disorders characterized by focal atrophy of the frontal and/or temporal cortices. These results in variable clinical manifestations collectively known as frontotemporal dementia (FTD) syndromes.
