A majority of amyloid PET scans led physicians to change how they managed a patient’s disease. The effect on later outcomes is yet to be come.
Transcranial, alternating electrical current restored neuronal synchrony in older people, rejuvenating working memory. For an hour or two.
A fleet of patient-derived neurons show that while an APP mutation shifts where γ-secretase takes its first bite, PS1 mutations blunt the enzyme’s second cut. Eventually, all mutations drive up the Aβ42:40 ratio.
Researchers publish 14 new AD variants. This includes one near WWOX, a gene that encodes a protein linked to tau and lipid metabolism.
Human cells show more phenotypic variation than mouse microglia, but the two match up well overall.
