Stored Samples

Banked Tissues collected Ante-mortem

Serum, plasma, whole blood, and DNA are collected in a fasting state from all Clinical Core participants and banked. Samples are stored as 1ml aliquots at -80 degrees. Cerebrospinal Fluid (CSF) from individuals eligible and willing to complete lumbar puncture is also available.

Banked Tissue collected Post-mortem

Brain tissue and CSF obtained from deceased Clinical Core participants, as well as tissue from decedents enrolled in the Wisconsin Brain Donor Program, are available to approved investigators. Banked tissues include right hemisphere blocks from patients with Alzheimer’s disease, Mild Cognitive Impairment, cognitively healthy older controls, and individuals with other dementias, including rare forms of dementia (e.g., CADASIL, FTD).
