Memory problems have been continually tied to anxiety in recent research. Studies have shown that increases in stress, anxiety, and depression can have powerful effects on a variety of types of memory. Research covered by the CBC is showing that people with more chronic levels of anxiety, depression, and worry (this group could possibly include those with generalized anxiety disorder) are more prone to develop something called mild cognitive impairment (MCI), which is seen as a precursor to Alzheimer's disease. This type of work is still in the early stages, but it hopefully is an incentive to find and continue treatment for anxiety. For more on GAD symptoms check here.
