Eligibility
Inclusion criteria
Inclusion criteria: 1. Meets NIA-AA criteria for MCI due to AD or probable AD dementia 2. Have a global CDR score
Exclusion criteria
Exclusion criteria: 1. Meets core clinical criteria for non-AD dementia 2. Two or more first degree relatives with a history of early-onset dementia suggestive of autosomal dominant transmission, unless known pathogenic mutations in APP, PSEN1, PSEN2, MAPT, GRN and C9ORF72 have been excluded 3. Known CLIA certified mutation in an ADAD gene (APP, PSEN1, PSEN2), or other autosomal dominant genes associated with other neurodegenerative disorders (MAPT, GRN, C9ORF72) 4. Contraindications to 3T MRI (e.g., claustrophobia, pacemaker, select aneurismal clip, artificial heart valve, select ear implants, select stents incompatible with 3T MRI, metal fragments or foreign objects in the eyes, skin or body, etc.) 5. Lifetime medical history of a brain disorder other than the disorder causing dementia except for headache (exceptions are allowed at the discretion of the Site PI - e.g., seizure disorder thought to be due to EOAD). 6. MRI scan with evidence of infection or focal lesions, cortical strokes, multiple lacunes (single lacune is allowable unless it meets criteria for strategic lacune affecting cognition) 7. Any significant systemic illness or unstable medical condition, which could lead to difficulty complying with the protocol (at the discretion of the Site PI) 8. Research radiation exposure will be assessed by the study physician. If the candidate participant has had more than one nuclear medicine study in the prior 12 months for research-related purposes, study inclusion will require approval from the PET Core 9. Investigational agents are prohibited 30 days prior to entry 10. Previous enrollment in a therapeutic trial targeting amyloid or tau 11. Participation in other clinical studies with neuropsychological measures, with the exception of participants who are co-enrolled in the NACC Uniform Data Set (UDS) protocol (Note: This criterion is intended to reduce repeat measures effects during neuropsychological testing. Exceptions are allowed at the discretion of the Site PI) 12. Lifetime history of schizophrenia spectrum disorders (DSM-5 criteria) 13. Current history (in previous 12 months) of DSM-5 diagnosis of mania, bipolar disorder with or without psychotic features 14. Current history (in previous 6 months) of moderate or severe substance abuse (nicotine or caffeine is allowed) 15. Suicidal behaviors in the past 12 months or active suicidal ideations 16. Residing in a 24-hour care skilled nursing facility (at the time of screening) 17. (For optional lumbar puncture procedure only): a. Clinical laboratory values must be within normal limits or, if abnormal, must be judged to be not clinically significant by the Site PI i. Platelet count <100,000/ml ii. INR>1.2 iii. Abnormal PT or PTT at screening b. Contraindications to the procedure, including but not limited to severe degenerative joint disease, deformity of the spine, history of a bleeding disorder c. Suspected elevated intracranial pressure, Arnold Chiari malformation or mass lesion d. Use of the anticoagulant medications such as but not limited to warfarin, rivaroxaban, dabigatran 18. Deemed ineligible by the Site P
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Rate of decline on cognitive, global, and functional tests; rates of change on imaging and fluid biomarkers; Longitudinal extent and rate of brain atrophy, amyloid and tau deposition; Discovery of new AD genetic risk variants | — |
Secondary
| Measure | Time frame |
|---|---|
| (1) collection of DNA from EOAD participants for exploratory studies applying next generation sequencing; (2) collection and banking of clinical, biofluid and imaging measures for future research and sharing with the larger research community; and (3) establishing a network of EOAD sites that will enable future planning and implementation of clinical trials in EOAD. | — |
