Insulin resistant people with type 2 diabetes are more likely to develop plaques in their brains which are associated with Alzheimer's disease.
According to the University of Michigan, dementia strikes about 50% of people who reach the age of 85. Of those, about 60% go on to develop Alzheimer's disease.
The major culprits causing Alzheimer's or nerve damage in the brain:
1. Insulin resistance/diabetes
2. Insufficient omega-3 fats
3. Aluminum toxicity
4. Mercury toxicity
5. Lack of mental/brain stimulation
6. Anticholinergic drugs
Anticholinergic drugs is one class of drugs that have been linded to increased risk of dementia and Alzheimer's disease. Available both over-the-counter and by prescription, anticholinergic drugs include night-time pain relievers, antihistamines, and other sleep aids.
Anticholinergic drugs block a nervous system neurotransmitter called acetylcholine. Those suffering from Alzheimer's disease typically have a marked shortage of acetylcholine.
