Brief Summary:
The Evidence Amyloid Study EEG (EASE) establishes an open-label, longitudinal cohort study to measure of neurological functioning during the onset and progression of cognitive decline in preclinical Alzheimer's patients using quantitative electroencephalography (qEEG) measures (P300, P50, and reaction time). Participants will be scanned using the ElectroCap (FDA Class II) and/or the WAVi headset with the WAVi EEG P300/P50 system, along with the structured clinical interviews and assessments for baseline screening or mild cognitive impairment which are standard of care.

Study Type : Observational [Patient Registry]
Estimated Enrollment : 2000 participants
Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 24 Months
Official Title: Quantitative EEG for Assessment of Mild Cognitive Impairment Associated With Preclinical Alzheimer's Disease - Evidence for Amyloid Indication Study
Actual Study Start Date : July 20, 2018
Estimated Primary Completion Date : November 15, 2020
Estimated Study Completion Date : November 30, 2020

Group/Cohort Intervention/treatment
Early stage of MCI symptoms
Subjects with cognitive decline representing MCI symptomology and with previous PET amyloid-beta (Aβ) imaging results.
Device: EEG scan
WAVi EEG and evoked potential platform. Participants will be scanned using the ElectroCap (FDA Class II) and/or the WAVi Headset with the WAVi Co EEG P300 system, along with the structured clinical interviews and assessments for the various ailments or baseline screenings

Primary Outcome Measures :
  1. Patient meeting Appropriate Use Criteria (AUC) with EEG brain scan - P300 and P50 will be measured for correlation between P300 and P50 with amyloid deposition. [ Time Frame: 10 days ]
    Test whether qEEG P300 and P50 waveform amplitudes and auditory response times will lead to correlation with amyloid deposition

Inclusion Criteria:

  • 65 and older;
  • Medicare beneficiary;
  • Diagnosis of MCI or dementia, according to DSM-IV and/or National Institutes of Aging-Alzheimer's Association criteria, verified by a dementia specialist within 24 months (American Psychiatric Association. 2000; McKhann et al. 2011; Albert et al. 2011);
  • Cognitive complaint verified by objectively confirmed cognitive impairment;
  • Alzheimer's disease is a diagnostic considerationExclusion Criteria:
  • Head MRI and/or CT within 24 months prior to enrollment;

Exclusion Criteria:

  • Normal cognition or subjective complaints that are not verified by cognitive testing.
  • Knowledge of amyloid status, in the opinion of the referring dementia expert, may cause significant psychological harm or otherwise negatively impact the patient or family.
  • Scan being ordered for nonmedical purposes (e.g., legal, insurance coverage, or employment screening).
  • Cancer requiring active therapy (excluding non-melanoma skin cancer);
  • Life expectancy less than 24 months based on medical co-morbidities;
  • Residence in a skilled nursing facility.
