PPA Group
1. Are currently enrolled in the longitudinal study of frontotemporal lobular degeneration at the Dementia Research Centre (DRC) at University College London (UCL)
2. Patients with PPA will have undergone detailed neuropsychological assessments and will be classified in one of three syndromic groups: PNFA, LPA, or SD
3. Can tolerate a PET scan procedure
PCA-AD Group
1. 1.Are currently enrolled in the longitudinal study of posterior cortical atrophy at the Dementia Research Centre (DRC)
2. Patients with PCA-AD will have undergone detailed neurological assessments and will fulfil the following criteria:
2.1. Insidious onset of cognitive decline, sufficient to interfere with activities of daily living, with absence of structural lesion or significant whilte matter disease on magnetic resonnace imaging (MRI)
2.2. Relatively preserved episodic memory; deficits on standard psychological testing in at least two of four posterior cortical functions:
2.2.1. Object perception
2.2.2. Space perception
2.2.3. Calculation
2.2.4. Spelling
3. Can tolerate a PET scan procedure

Participants may be male or female.
Subjects in the cognitively normal group must be aged 55 ?- 90 years.
