Actos Significantly Decreases Alzheimer’s Risk

Diabetics get a lot more dementia than the average person. Yet diabetics taking FDA-approved Actos get a lot LESS dementia than the average person - 47% less. That's about half the rate. Find out more.

The primary cause of type 2 diabetes is excessive body weight and not enough exercise. It begins with insulin resistance, a condition in which cells fail to respond to insulin properly. The result is high blood sugar levels over a prolonged period.

Once the disease reaches an advanced stage, the body stops producing insulin altogether, which means that it has to be administered externally. Type 2 diabetes most commonly occurs in late adulthood.

Diabetes & Dementia

It has long been known that people with diabetes have a greater risk of developing dementia than non-diabetics. The association is so close that researchers have conceptually called Alzheimer’s “type 3 diabetes.

The natural question becomes, how does antidiabetic medication influence dementia risk? Research has been going on in this area for year with some positive results. Now, at a whole new level, neurologist Michael Heneka and the demographers Anne Fink and Gabriele Doblhammer investigated this issue in a new, breakthrough study. Their work is based on data from the years 2004 to 2010 provided by the German public health insurance company AOK. These data set comprises information about diseases and medication related to more than 145,000 men and women aged 60 and over.

Long-term treatment reduced dementia risk

The analysis confirmed previous findings that diabetics have an increased risk of developing dementia. However, it was also found that this risk can significantly be modified by Actos, also known by its generic name pioglitazone. This drug is taken as tablets. It is applied in short-term as well as in long-term treatment of diabetes as long as the body is still capable of producing its own insulin.

Treatment with pioglitazone showed a remarkable side benefit. It was able to significantly decrease the risk of dementia,” says Doblhammer. “The longer the treatment, the lower the risk.” Risk reduction was most noticeable when the drug was administered for at least two years. Diabetics given this treatment developed dementia less often than non-diabetics. Doblhammer: “The risk of developing dementia was around 47 percent lower than in non-diabetics, i.e. only about half as large.

Metformin – another frequently prescribed antidiabetic drug – also lowered the risk of developing dementia. However, the effect was lower than that of pioglitazone.

Protection against nerve cell damage

Pioglitazone improves the effect of the body’s own insulin. Moreover, laboratory tests have long indicated that it also protects the nerve cells. The current results are therefore no surprise to neuroscientist Michael Heneka. “Pioglitazone is an anti-inflammatory drug that also inhibits the deposition of harmful proteins in the brain,” he says.

However, Heneka emphasizes that the exact mechanisms are not yet understood: “Our study suggests that pioglitazone has a preventive effect. This happens when the drug is taken before symptoms of dementia manifest. Thus, it protects in particular against Alzheimer’s, the most common form of dementia. The causes for this, whether pioglitazone only has this protective effect in diabetics or if it would also work in non-diabetics – all these questions have yet to be answered. The next logical step would therefore be clinical studies. These studies would specifically investigate the effect of pioglitazone and other antidiabetics on dementia.”

Update: On the Other Hand

Newer, further investigations have shown that, in addition to the positive results above, there are also negative effects of Metformin on Alzheimer’s. To weigh the positives against the negatives, see the study,
