Confirmed (NIH release + Nature news, Sept. 23, 2026)

On Sept. 23, 2026, the National Institutes of Health announced a PsychAD Consortium single-cell atlas of the dorsolateral prefrontal cortex using more than 6.3 million nuclei from 1,494 donors, spanning Alzheimer’s-related dementias, schizophrenia, and bipolar disorder. Nature news covered the same-day collection of studies.

On Sept. 23, 2026, the National Institutes of Health announced a PsychAD Consortium single-cell atlas of the dorsolateral prefrontal cortex.

The atlas uses more than 6.3 million nuclei from brain tissue of 1,494 donors, from infants to centenarians.

The donors span Alzheimer’s-related dementias, schizophrenia, and bipolar disorder.

National Institute on Aging director Richard Hodes called it the most comprehensive population-scale molecular mapping of these disorders to date.

Nature news the same day said the work was published in a collection of eight studies, including three papers in Nature.
