Amyloid deposition in semantic dementia: a positron emission tomography study

Pittsburgh compound B ([11C]‐PIB) identifies amyloid‐β (Aβ) deposition in vivo. Asymptomatic Aβ deposition has been reported consistently in some healthy older subjects. Of patients with frontotemporal dementia, those who have later onset have a higher potential for Aβ deposition.
