Drug treatments in Alzheimer’s disease
Open accessAbstract
Despite the significant public health issue that it poses, only five medical treatments have been approved for Alzheimer's disease (AD) and these act to control symptoms rather than alter the course of the disease. Studies of potential disease-modifying therapy have generally been undertaken in patients with clinically detectable disease, yet evidence suggests that the pathological changes associated with AD begin several years before this. It is possible that pharmacological therapy may be beneficial in this pre-clinical stage before the neurodegenerative process is established. Techniques providing earlier diagnosis, such as cerebrospinal fluid biomarkers and amyloid positron emission tomography neuroimaging, are key to testing this theory in clinical trials. Recent results from trials of agents such as aducanumab are encouraging but must also be interpreted with caution. Such medicines could potentially delay the onset of dementia and would therefore markedly reduce its prevalence. However, we currently remain a good distance away from clinically available disease-modifying therapy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
