Abstract: Our paper on loss of neurons in the Nucleus Basalis of Meynert (now considered part of the cholinergic basal forebrain) in Alzheimer disease (AD) stimulated scientific interest in this little studied brain region. Our subsequent studies associated pathology in the basal forebrain with other dementias, such as Parkinson's disease, and with neurotransmitter receptor changes, such as in nicotinic receptors. We and many others worked to develop medications to treat AD through cholinergic mechanisms and eventually four cholinesterase inhibitors were approved. However the effect sizes of currently available drugs are modest and ethical issues in conducting research in dementia are challenging. …In Cleveland we came to focus on the goals of improving quality of life and the importance on non-pharmacological approaches to treatment. International efforts were organized to improve the efficiency of drug development and to focus on important cultural and pharmacoeconomic issues. Eventually I became concerned about the very way we conceive AD and related concepts like MCI (mild cognitive impairment). As the hundredth anniversary of the first case approaches I am helping to organize meetings to reflect deeply on what we have learned and how to imagine creating a more positive future for persons affected by what I used to call AD.
