It has been previously demonstrated that prepulse inhibition (PPI) is modulated by neurosteroids and in vivo research in mice has shown that PPI of the startle, a well-validated index of sensorimotor gating, is reduced by the neurosteroid allopregnanolone (AP). In recent work, a group of international researchers aimed to assess whether AP might mediate the PPI-disrupting effects of acute stress.

Researchers at the University of Cincinnati have published data showing that in patients with dominantly inherited Alzheimer’s disease (AD)-causing mutations, high levels of soluble amyloid-β42 (Aβ42) in the cerebrospinal fluid (CSF) predicted a reduced risk of developing dementia over 3 years. Their work, which appeared in the Oct. 4, 2022, print issue of the Journal of Alzheimer’s Disease after earlier publication online, suggests that the problem with amyloid in AD may be a lack of soluble amyloid-β, rather than a surfeit of plaques.
