Cognitive decline should not be considered a normal characteristic of aging.

Researchers studied brain slices from aged mice and demonstrated that changes in the electrical activity of the brain can alter cognition. The results were published in the journal EMBO Molecular Medicine.

In a previous study, researchers had found that slower electrical conduction in the brain is associated with poor cognition in older rodents.

In the more recent study, the scientists reported that reduced nerve transmission in the older rodent brain can be rescued by cholesterol perfusion.

The new cholesterol guidelines will ensure that tens of millions of asymptomatic Americans will be encouraged to take statin drugs in order to lower their cholesterol.

But there is no good data showing that an asymptomatic person will benefit from lowering their cholesterol level with chemicals.

Unfortunately, there are a host of adverse side effects associated with statins, including sudden amnesia, memory loss, and a decline in brain function.

None of these side effects should be a surprise. The brain has the highest cholesterol content in the body.

Cholesterol is required to protect the brain and ensure nerve signal transmission.
