Cath Stanley, of the UK's Huntington's Disease Association said she was not surprised by the findings.
Cholinesterase inhibitors are not useful in dementia caused by Huntington's disease or traumatic brain injury.
CNN: Better understanding of dementia leading to more effective therapies
In 1983 researchers found the approximate location of the gene for Huntington's disease, the incurable brain illness.
The drug is also being tested against Huntington's disease, an inherited condition in which the brain slowly degenerates.
That group had isolated the gene for Huntington's disease in 1983, which paved the way for the human genome project.
DNA, medical screening by insurance companies and irksome who-to-tell questions that arise with rare, though horrible, late-onset genetic killers such as Huntington's disease.
Meanwhile, genetic carrier tests are more accurate because scientists know more about single gene disorders, such as Huntington's disease and sickle cell anemia, Faucett said.

He was only 55 years old and suffered from Huntington's Disease.
It wouldn't be doing so were it not for the Cure Huntington's Disease Initiative, a group that in 2004 turned itself into a biotech called CHDI.
Since 1983, when Huntington's disease was found to be correlated with a particular chromosome, health researchers have identified no fewer than 1, 400 diseases associated with single genes.
Compounds in preclinical tests target cystic fibrosis (30, 000 people plus a thousand new cases per year), Huntington's disease (30, 000 cases) and Rett syndrome, a rare inherited brain disorder.
For some inherited disorders such as Huntington's disease and cystic fibrosis, where a change in just a single gene causes a potentially devastating condition, highly predictive genetic tests already available.
Huntington's disease is an hereditary neurological disorder of the central nervous system that causes progressive degeneration of cells in the brain, slowly impairing a person's ability to walk, think, talk and reason.
Genes for rare inherited ills such as Huntington's disease guarantee you will get sick, but many of the new genes being discovered for diabetes and other common diseases tweak your risk by only so much, such as 30%--not enough to make you change your life.
Preventing these gobs of protein debris from wreaking havoc inside the brain may someday help fight not only Alzheimer's disease, but also Huntington's, Lou Gehrig's and Parkinson's.
