This review summarizes the clinical, imaging, and pathological
features of frontotemporal dementia (FTD). Clinicians have become
increasingly sensitive to FTD in the differential diagnosis
of Alzheimer's disease. Clinical subgroups of FTD patients
have been recognized, including patients with progressive
non-fluent aphasia, semantic dementia, and behavioral disorder
with executive difficulty. The clinical, neuroimaging and
neuropathological profiles associated with these clinically
defined subgroups are examined. (JINS, 2002, 8,
566–583.)
