Is There An Association Between A Gluten Intolerance And Alzheimer’s Disease?

April 2, 2011 · Filed Under Alzheimers Disease 

Could immune reactions to gluten lead to the symptoms associated with Alzheimer’s disease? This is an intriguing question and I suspect that the connection is very likely.

Immunological reactions to gluten can lead to brain atrophy, nerve damage, nutrient deficiencies, hypoperfused (low blood flow) brain regions, vasculitis (inflamed blood vessels in the brain), and white matter lesions in the brain. This could potentially contribute to  to Alzheimer’s disease or dementia symptoms.

One study mentioned that two patients with Alzheimer’s disease were later found to have celiac disease. Once a gluten-free diet was initiated, their cognitive symptoms improved (15). The study findings are not really that surprising, immune reactions against gluten and cross reactions against brain tissue can occur with a gluten intolerance and this could contribute to cognitive decline. Associated nutrient deficiencies (with intestinal villi damage) can certainly affect a patient’s cognitive abilities as well.

I think researchers need to look closer at this possibility. Many families are negatively impacted by this disease. If gluten is the underlying culprit, a therapeutic gluten-free diet would be an attractive treatment that may improve their cognitive status.

This study just mentioned the possible connection to celiac disease, I strongly suspect that non-celiac gluten intolerance could also contribute to Alzheimer’s disease. Therefore negative celiac tests wouldn’t rule out this possible connection. Testing for non-celiac gluten intolerance would also need to occur.

    Thanks for posting this, Shelly. A family friend has unfortunately just been put in a home because of her Alzheimer’s. We suspect she has celiac and gluten sensitivity, as she has had thyroid issues and other health problems. We tried to tell her and her doctors, but it went nowhere, and it was just too late. She is rapidly declining and does not know her own husband at this point. It’s so very sad.

    Looking at various family members, I suspect a strong connection to gluten as well as to sugar (diabetes of the brain) as an underlying cause of Alzheimer’s Disease.

    So sad! It can be very difficult to advocate due to the lack of awareness in the medical profession with nurses and doctors. Perhaps it might help if the doctor looks at this study along with some research that demonstrates the neurological and cognitive symptoms that can be associated with a gluten intolerance. It would be interesting to see what kind of effect a trial gluten-free diet (along with vitamins, probiotics and omega 3 supplements) would have on her cognitive status, even at this point. Testing for additional food allergies might be beneficial as well.

    Best of luck Alison:)

    Listening to the car radio the other day I heard a statement from the commentator that a gluten-free diet could aid in memory deficit and with omega-3 would improve memory considerably in the elderly. I am researching this gluten-free diet now and as an RN would like as much info on alz. disease as is available. At age 74 I still work 30-40 hours a week. I would like to continue as retirement is not at all what I thought it would be. Thanks Doug Hamilton, Ocala,Fl
