BIOmarkers for cogNitive Impairment due to Cerebral Amyloid Angiopathy (BIONIC)

Recruitment & Eligibility

Status: Completed

Sex: Not specified

Target Recruitment: 375

Inclusion Criteria

Important notice: we plan to use left-over body fluids (CSF, serum) from neurological controls and dementia patients. We will not actively recruit new patients in these categories.
However, we plan to recruit a maximum of 40 new CAA patients to this study; therefore the inclusion and exclusion criteria listed below only apply to this category of patients. The other patient groups are only listed in this ABR form (see above) for the sake of completeness.;Inclusion criteria for CAA patients:
In order to be eligible to participate, a subject must meet the following criteria:
- Fulfilment of the modified Boston criteria for CAA (Linn, 2010; Smith, 2003)
- Subjects are mentally competent to take a decision on participation.
- Written informed consent
- Age >55 years

Exclusion Criteria

- History of neurological or psychiatric disease
- Allergy to local anesthetic agents
