Statins May Slow Alzheimer’s Progression, Study Finds – People with Alzheimer’s dementia who took statins to lower their blood cholesterol levels may have experienced slower cognitive decline compared to those who didn’t take statins, according to a new study published in Alzheimer Research and Therapy.
The study, led by researchers at Karolinska Institutet in Sweden, is observational, meaning it can’t definitively prove that statins caused the slower decline. However, the findings add to a growing body of evidence suggesting that statins may have brain-protective effects.
“Our study suggests that statins may be protective against cognitive decline in Alzheimer’s disease,” said lead author Sara Garcia-Ptacek, an associate professor of neuroscience at Karolinska Institutet. “However, more research is needed to confirm these findings and to determine which patients are most likely to benefit from statin treatment.”
Statins and the Brain
Statins are a class of drugs that work by lowering levels of “bad” cholesterol (LDL) in the blood. They are primarily used to prevent heart disease and stroke. However, in recent years, research has suggested that statins may also have beneficial effects on the brain.
For example, some studies have shown that statins can reduce the risk of developing Alzheimer’s disease. Other studies have shown that statins can improve cognitive function in people with Alzheimer’s disease.
The new study adds to this body of evidence. In the study, researchers analyzed data from more than 15,500 people with Alzheimer’s dementia. They found that those who took statins had a slower decline in cognitive function over time, as measured by standardized tests.
More Research Needed
It is important to note that the study was observational, meaning that researchers cannot conclude that statins caused the slower cognitive decline. It is possible that other factors, such as differences in health or lifestyle, could have explained the findings.
“Our study is a first step,” Garcia-Ptacek said. “More research is needed to confirm our findings and to determine whether statins can be used to treat or prevent Alzheimer’s disease.”
Implications for Patients
The findings of the new study may have implications for patients with Alzheimer’s disease. If confirmed by further research, statins could potentially be used as a new treatment for the disease.
However, it is important to talk to a doctor before taking any new medication, including statins. Statins can have side effects, and they may not be appropriate for everyone.
Conclusion
The new study suggests that statins may slow the progression of Alzheimer’s disease. However, more research is needed to confirm these findings. If you have Alzheimer’s disease, talk to your doctor about whether statins may be right for you.
