    baseline, 1 year

Study Arms (1)

Tau PET Scan, F-18 AV 1451

EXPERIMENTAL

All subjects will received a Tau PET scan.

Drug: F-18 AV 1451

Interventions

Tau PET scan

Also known as: Tau binding agent
Tau PET Scan, F-18 AV 1451

Eligibility Criteria

Age35 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Must be over 35 years of age and present with gradual progression of PSP-related symtoms
  • Must have an informant or study partner that can provide independent information of functioning.
  • Must meet criteria for possible or probable Progressive Supranuclear Palsy. To fulfill criteria for possible PSP, subjects must have a gradually progressive disorder with either vertical (upward or downward) supranuclear palsy or both slowing of vertical saccades and prominent postural instability with falls in the first year of disease onset. To fulfill criteria for probable PSP, subjects must have vertical (upward or downward gaze) supranuclear palsy and prominent postural instability with falls in the first year of disease onset.

You may not qualify if:

  • Subjects with concurrent illnesses that could account for their symptoms, such as traumatic brain injury, encephalitis, strokes or developmental syndromes will be excluded.
  • Women that are pregnant or post-partum and breast-feeding will be excluded.
  • Subjects will be excluded from the study if they have any of the following genetic conditions which can increase the chance of cancer: Cowden disease, Lynch syndrome, hypogammaglobulinemia, Wiskott-Aldrich syndrome, and Down's syndrome.
  • Subjects will also be excluded if MRI is contraindicated (metal in head, cardiac pace maker, e.t.c.), if there is severe claustrophobia, if there are conditions that may confound brain imaging studies (e.g. structural abnormalities, including subdural hematoma, intracranial neoplasm or large cortical infarcts), or if they are medically unstable or are on medications that might affect brain structure or metabolism (e.g. chemotherapy).
  • Subjects will also be excluded if they do not have an informant, or do not consent to research.
