Abstract

Dementias occurring in Alzheimer's disease, Parkinson's disease, and progressive supranuclear palsy are associated with dysfunction and death of neurons in a variety of cell populations, including cholinergic, monoaminergic, and peptidergic systems. In the present investigation of these three disorders, we demonstrated decreased levels of corticotropin releasing factor (CRF)-like immunoreactivity in the frontal, temporal, and occipital poles of the neocortex. Moreover, reductions in peptidergic immunoreactivity correlated with reductions in the activity of choline acetyltransferase, the enzyme that catalyzes the formation of acetylcholine. The reduction in cortical CRF levels may be due to abnormalities of intrinsic cortical neurons or to dysfunction in neurons that contain CRF and innervate cortex.
