This frequent blood disorder is defined by a decrease in red blood cells. These cells carry oxygen, so frequent fatigue is a common symptom. The condition suffers from more than three million Americans. Some studies have found a link between anemia and an increased risk of dementia in older adults. One of the most common causes of anemia is iron deficiency, which may be the result of poor diet; it can also be a side effect of some medicines.
It worries that by removing oxygen from the brain, anemia can lead to the type of damage that occurs in people with Alzheimer's disease. The results of an 11-year study involving over 2 500 people aged 70-79 showed that people with anemia had a 40 percent higher risk of developing dementia than people who did not have anemia.

Depression and anxiety

"There is plenty of evidence that people who are committed to developing Alzheimer's dementia are sometimes the first thing you see is depression or anxiety," explains MD Pierre Tariot, director of the Banner Alzheimer's Institute in Phoenix, Arizona. However, scientists say these mood disorders may not be just a symptom of Alzheimer's disease – they can in fact be risk factors for developing this disease. Because depression and anxiety can increase cortisol stress hormone levels, one theory is that chronically high levels of cortisol can damage the brain.
Interestingly, antidepressant drugs are being studied as a potential treatment for Alzheimer's disease. "Some antidepressants have an antiamyloid [a protein associated with Alzheimer’s] properties with sufficient credibility that there are two antidepressant studies to see if we can derail the Alzheimer's with these drugs, "says Dr. Tariot, making sure you know these 10 early signs of Alzheimer's disease.

The link between diabetes and Alzheimer's disease is relatively strong. "Diabetes is probably a risk factor for many reasons," says Dr. Tariot. "The top of the list is that the disease leads to abnormal inflammatory responses in multiple organs – including the brain – and another reason is that the insulin signaling pathway is also one of the pathways involved in the breakdown of amyloid and finally diabetes contributes to cerebrovascular disease [conditions that raise the risk of stroke], a major factor in Alzheimer's disease. "
Nearly 21 million Americans suffer from diabetes and it is estimated that 54 million of them have prediabetes, Alzheimer's Association claims. But the disease can be controlled by dietary changes and lifestyle changes and medication, if necessary, to reduce the risk. Learn about more than 70 simple ways to prevent diabetes.
