Study summary

The goal of this study is to construct a large database of EEG recordings from elderly individuals in predefined groups. The purpose of this database is to select groups of EEG recordings from the database in order to compare the electrophysiology, as measured by EEG, of the groups.

In the clinical trial part all individuals are treated exactly the same and are therefore considered a single group. The categorization is performed during the data analysis.

The groups in the data analysis will initially be based on the following:

  1. Healthy controls
  2. Mild Cognitive Impairment
  3. Alzheimers Disease (AD)
  4. Lewy-body Dementia
  5. Parkinsons Disease Dementia
  6. Vascular Dementia (VaD)
  7. Frontotemporal Dementia (FTD)
  8. Depression

Other groups will be added if needed.

What researchers measure

Primary outcomes

  1. Classification system for dementia based on EEG

    The EEGs recorded in the trial will be categorized into controls or predefined clinical groups based on the participants' clinical diagnosis. The classification system will be constructed using this categorization.

    Time frame: The quality of the classification system will be evaluated regularly, at least every 6 months, up to 6 years.
