A Promising New Approach to Alzheimer’s Disease Treatment
A groundbreaking new study has revealed a potential breakthrough in the treatment of Alzheimer’s disease, inspired by a compound found in everyday herbs.
Carnosic acid, commonly found in rosemary and sage, is renowned for its antioxidant and anti-inflammatory properties. However, its instability in its pure form has hindered its therapeutic potential.
In a recent development, researchers in California have successfully synthesized a stable derivative of carnosic acid that has shown promising results in mouse models of Alzheimer’s disease.
The mice treated with the stable derivative exhibited improved memory, increased neuron synapses, reduced inflammation, and enhanced removal of toxic proteins associated with Alzheimer’s.
Alzheimer’s disease is characterized by the loss of synapses, leading to impaired neuron communication and memory decline. The findings of this study address multiple hallmarks of the disease, offering new hope for effective treatment.

Dr. Stuart Lipton, a neuroscientist from the Scripps Research Institute, commented on the study’s findings, stating, “We observed significant improvements in memory across various tests with the drug, almost restoring it to normal levels.”
One of the primary challenges faced by the researchers was stabilizing carnosic acid in a form that could effectively cross the blood-brain barrier. Through meticulous experimentation, they identified a di-acetylated derivative (diAcCA) that demonstrated improved bioavailability and reached therapeutic levels in the brain rapidly.
In a three-month study involving mice with Alzheimer’s, those treated with diAcCA showed no signs of toxicity and exhibited reduced accumulation of Alzheimer’s-related proteins in their brains.
Dr. Lipton highlighted the compound’s anti-inflammatory and antioxidant properties, which led to increased synaptic density and decreased levels of misfolded proteins implicated in Alzheimer’s pathology.
While these findings are promising, further clinical trials are essential to validate the efficacy of diAcCA in human subjects. The researchers are optimistic about its potential application in other inflammatory conditions such as type 2 diabetes and Parkinson’s disease.
The prospect of combining diAcCA with existing Alzheimer’s treatments is also being explored, with hopes of enhancing their effectiveness and minimizing side effects. As diAcCA is a modified form of the safe-to-consume carnosic acid, the development of new medications could be expedited.
Dr. Lipton concluded, “This novel compound has the potential to enhance the efficacy of current Alzheimer’s therapies and pave the way for innovative treatment strategies.”
