Alzheimer’s Disease & AD Related Dementia (AD/ADRD)

NDRI’s Human Tissue and Organs for Research Resource (HTORR) Program has been funded by the National Institutes of Health (NIH) for over 30 years to support research programs across multiple disciplines, including neuroscience. It is through the HTORR program that NDRI provides biomedical investigators with human organs and tissues from normal donors as well as Alzheimer’s Disease and AD-related dementia (AD/ADRD) donors using customized procurement, processing, and preservation and distribution protocols. NDRI recently received a supplemental grant from the National Institute on Aging (NIA) to increase its focus on AD/ADRD. 

We tailor human tissue acquisition to meet the specific needs of approved research projects. NDRI can provide tissue types for all of your experimental needs. This includes:

  • CNS and PNS structures - brain, spinal cord, dorsal root ganglia, sympathetic ganglia, peripheral nerves
  • Fixed tissue, frozen tissue, or fresh tissue shipped on ice in culture media with antibiotics
  • Tissues from any body system
  • CSF and plasma, from ADRD living patients with MMSE and relevant clinical information


NDRI was recently awarded a research resource grant of $334,446 from the National Institute on Aging (NIA) to support the development of the Ocular Tissue Resource for Alzheimer’s Disease (OTRAD). While significant advances continue to be made with the identification of blood-based biomarkers for Alzheimer’s disease (AD), there is an emergent interest in the use of ocular imaging or other ocular biomarkers as a parallel approach in early detection of the disease.
