Abstract

Alzheimer's disease (AD) is one of the most common neurodegenerative diseases. AD patients usually present symptoms, such as cognitive dysfunction, progressive memory loss, and other manifestations. With the increasing number of AD cases worldwide, there is an urgent need to develop effective drug treatments. Currently, drugs targeting AD symptoms may not change or prevent the progression of the disease. Curcumin, a polyphenol extracted from the turmeric herb, has been used for the treatment of AD. In this review, we summarized both cellular and animal studies and described the mechanism of action of curcumin in altering the pathological features of AD. Curcumin attenuates the formation of amyloid-β plaques and promotes its decomposition, reduces the phosphorylation of tau, improves its clearance rate, and binds with copper to reduce cholesterol. It changes the activity of microglia, suppresses acetylcholinesterase, regulates insulin signal transduction, and exhibits antioxidant properties. Studies have found that curcumin can promote nerve repair and has a significant effect on AD. However, the low bioavailability of curcumin may hinder its use as a therapeutic agent. If this limitation can be overcome, curcumin may emerge as a promising drug for the treatment of AD.

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.
