Alzheimer's Disease Data (SEA-AD)
Seattle Alzheimer's Disease Brain Cell Atlas (SEA-AD) Study Documentation, Data, and Downloads
The Seattle Alzheimer’s Disease Brain Cell Atlas (SEA-AD) consortium strives to gain a deep molecular and cellular understanding of the early pathogenesis of Alzheimer’s disease. This page includes links to access and download raw and processed data generated as part of SEA-AD, along with documentation describing aspects of data generation from cohort selection to tissue processing, to detailed protocols for collecting and analyzing data from each modality.
Access and download data
SEA-AD includes data from multiple brain regions and data modalities. All of the data included in our public resources, along with additional data not yet fully analyzed is freely and publicly available online. This graphic summarizes all data currently available:
Values of A+B indicate the number of SEA-AD and reference donors, respectively. Abbreviations: MTG, middle temporal gyrus; A9 (also called PFC), prefrontal cortex; STG, superior temporal gyrus; V1C, primary visual cortex; MEC/LEC/EC, medial/lateral entorhinal cortex; HIP, hippocampal formation.)
The table below includes a series of files or links out to all SEA-AD data. We provide these data to the research community. Accessing, downloading, and/or using these files must be done in accordance with the Allen Institute Terms of Use and the terms of our external partners. To use our resources, you must cite them in accordance with our Allen Institute Citation Policy. To cite a dataset, cite both the primary publication and the specific dataset. Citation of the primary publication, where one exists, is required when citing the data resource in a scientific publication.
