Summary
In a man of 47 with a 2-month history of Creutzfeldt-Jakob-disease verified neuropathologically a morphometric study of the nucleus basalis of Meynert, the major source of cholinergic innervation of the cortex, revealed a neuronal loss of 45%. The degeneration of these neurones may provide the morphological substrate of the cortical cholinergic deficiency which has been reported in this condition. The six subpopulations of the nucleus basalis were affected in different degrees. Neuronal loss was most pronounced in those subpopulations which project to cortical areas most affected by spongiosis and neuronal loss. It is suggested that maintenance of the nucleus basalis complex is a necessary condition for higher cortical function.
