Smell test challenge suggests clinical benefit for some before development of Alzheimer's:

Dementia Big
Researchers at Columbia University Medical Center (CUMC) and the New York State Psychiatric Institute (NYSPI) may have discovered a way to use a patient’s sense of smell to treat Alzheimer’s disease before it ever develops. Having an impaired sense of smell is recognized as one of the early signs of cognitive decline, before the clinical onset of Alzheimer’s disease. The researchers at CUMC and NYSPI have found a way to use that effect to determine if patients with mild cognitive impairment may respond to cholinesterase inhibitor drugs to treat Alzheimer’s disease.
