New Alzheimer's Research -- Severe Stress 2 yrs. prior to being diagnosed ...

New Trigger of Alzheimer’s Identified: Stress

October 10, 2013 
The study found that 72 percent—nearly three out of four—Alzheimer's patients had experienced severe emotional stress during the two years preceding their diagnosis. In the control group, only 26 percent, or one in four, had undergone major stress or grief. Most of the stresses encountered by the Alzheimer’s group involved:
  • Bereavement; death of a spouse, partner, or child
  • Violent experiences, such as assault or robbery
  • Car accidents
  • Financial problems, including “pension shock”
  • Diagnosis of a family member’s severe illness
When you consider all the adverse biological effects that stress and anxiety causes, it might not be such a stretch that severe stress could trigger Alzheimer’s. For example, researchers have found links between emotional distress and physical pain,3 chronic inflammation4 and even stillbirths.5

It can also wreak havoc on your gut health, which is critical to maintaining mental and physical health. Most recently, Forbes6 reported the findings of a study7 exploring the role of stress in rewiring your brain—in this case, altering your sense of smell:

“Two brain circuits that don’t typically “talk” to each other—one linked to our sense of smell and another linked to emotional processing—can become cross-wired when we experience stress-induced anxiety. The result is that stressful experiences transform normally neutral odors into bad ones...
‘After anxiety induction, neutral smells become clearly negative,’ explains Wen Li, a professor of psychology at the University of Wisconsin-Madison Waisman Center, who led the study. ‘People experiencing an increase in anxiety show a decrease in the perceived pleasantness of odors. It becomes more negative as anxiety increases.’”
