Evidence suggests that in Parkinson’s disease, a breakdown in lysosomal function allows lipids to build up within cells. Variants of the GBA1 gene, the strongest genetic risk factor for sporadic PD, ...

Alzforum webpages for each DIAN-TU-eligible variant now state “DIAN-TU eligibility: Yes” near the top of the page and an explanation under the Pathogenicity section (see, for example, PSEN1 M146V ).

Space, An Early Frontier. When a brain region is tau-negative by SUVR (green arrow, left), spatial extent (dark blue) correlates better with measures of disease severity than does SUVR (light blue).

For one, microglia hovering around plaques—the type that express the most TREM2—reportedly become desensitized to stimulation ...

Unger was able to nip calcium transients in the bud by injecting a “puff” of sTREM2 into the mouse brain with a pipette; this temporarily silenced nearby neurons, and it did so in wild-type or TREM2 ...

See α-Synuclein. Candidate tracer SY08 detects α-synuclein deposits in the brainstem (right) and parietal cortex (left) of ...

A new consortium aims to speed the pace of basic science discovery in AD and related diseases. A future AI assistant is to ...

Vaccine Step Down. A person’s probability of developing dementia over seven years increased with age. It was higher in the ...

Early onset familial Alzheimer disease (eFAD) is hereditary and marked by Alzheimer disease symptoms that appear at an unusually early age. Symptoms can start in a person's thirties, forties, and ...

The gene PSEN2 encodes presenilin-2, a subunit of γ-secretase, the aspartyl protease responsible for Aβ generation. Missense mutations in PSEN2 are a rare cause of early onset Alzheimer's disease.
