Inhaled Insulin for Alzheimer’s Dementia: An Editorial

Rate This

Alzheimer’s dementia (AD) is a progressive disorder with no identifiable cause or effective treatment. All the drug treatments available today appear to have major side effects and the cognitive improvement is only marginal.

Now there is a study showing that intranasal insulin spray may be of benefit in patients with Alzheimer’s dementia. The latest study done by Suzanne Craft, PhD, from the Veterans Affairs Puget Sound Health Care System in Seattle, reveals that individuals who received 20 IU of intranasal insulin daily for four months had improvement in their cognition and overall function (1).

The researchers indicate that insulin is critical for normal brain function and alteration in its metabolism may be a contributing factor to the development of Alzheimer's disease. The researchers mention that because some patients with AD have lower levels of insulin in the brain, perhaps delivering supplemental can help improve cognition.

The present study showed that both the 20 and 40 IU of insulin led to preservation of function in carrying out daily living activities in AD patients. This improvement was not seen in patients with milder symptoms. In additon, the researchers found no change in the AD biomarkers like tau protein.

More importantly, a few patients also underwent PET assessment after completion of the study. The imaging studies revealed less dementia-related hypometabolism in several areas of the brain in patients receiving insulin. In this study no serious adverse reactions were noted.

Similar studies in animals have also shown that insulin may be acting via receptors in the frontal cortex (2).

So what does this mean for the consumer?

While these results may sound impressive they are fraught with errors. To date, there is no imaging technique that can reliably make a diagnosis of Alzheimer's dementia.

Moreover, there is no reliable way to measure insulin levels in the brain, asides from autopsy specimens. To claim that AD patients have low levels of insulin is false, because there is no scientific evidence for this statement that I have read.

In my opinion the study is not bona fide at all.

there is little liklihood for hypoglycemia because of mode of administration ,intranasal.

There wereno adverseaffects reported in this and some smaller studies prior to this one.

Ther is a higher incidence of Ad in diabetics.

As we look at the treatment options for Alzheimer's Disease let us keep an open mind as to all options available. There is not a known cure for Alzheimer's as yet. We hope to see this sometime, hopefully not far down the road. In the meantime the use of pharmaceutical medications have at least helped Alzheimer's patients to have some success. There are also natural supplements which-with the use of the pharmaceuticals-may take things a step further. Many people who have participated in medical research have seen significant changes. In as little as 24 months people have been able to go back to some form of occupations. So many of us are not aware of this because unless someone pays to have this heard it is kept under a rock. God Bless those who take that extra step to look a little deeper. Most of us are too devastated to do so and need help from those who keep an open mind. My book, The Dynamite Story of Alzheimer's Recoveries reflects hope for Alzheimer's
disease patients and caregivers. Unfortunately the press does not care to cover this information.
