Unknown; MRI from two affected mutation carriers showed atrophy of the medial temporal lobe. SPECT showed hypoperfusion of the posterior cingulate gyri and other cortical areas.

N2a cells transfected with mutant PSEN1 secreted significantly more Aβ42 than cells expressing wild-type PSEN1. The Aβ42:Aβ40 ratio was also increased.
