Brief summary

The overall goal of this imaging trial is to evaluate crosssectional difference and longitudinal changes of \[18F\]PI-2620, a tau targeted positron emission computed tomography radioligand, in cognitively normal individuals, and subjects with mild cognitive impairment and Alzheimer's disease.

Interventions

Imaging for evaluating the accumulation of abnormal tau protein in the brain

Inclusion criteria

1. General Subject Inclusion Criteria In order to be eligible for participation in this trial, the subject must: * Be ≥ 40 and \< 85 years of age at the Screening Visit. * Be able to read at a 6th grade level or equivalent, (as determined by the investigator, and must have a history of academic achievement and/or employment sufficient to exclude mental retardation.) * Be able to speak, read, hear, and understand the language of the trial staff, and the informed consent form, and possess the ability to respond verbally to questions, follow instructions, and complete questionnaires and detailed neuropsychological test. * Have results of clinical laboratory tests/physical examination, vital signs, and ECG within normal limits (at 90 days prior to \[18F\]PI-2620 positron emission computed tomography) or clinically acceptable to the investigator at screening. * If female, not be of childbearing potential as indicated by one of the following * Each subject (or legal representative) must sign the informed consent form in accordance with local requirements after the scope and nature of the investigation have been explained to them, and before screening assessments. 2. Cognitively normal individuals 3. Subjects with Mild Cognitive Impairment 4. Subjects with Alzheimer Disease
