Reversible Causes of Cognitive Impairment
Quite a few cognitive difficulties don't have anything to accomplish with dementia and will be fully treatable. A study while in the Journal of Dementia & Neuropsychologia discovered that almost twenty% of cognitive Ailments may have reversible will cause, meaning they are often treated.
Widespread reversible causes incorporate:

Thyroid, kidney or liver problems
Snooze apnea and other rest Diseases
Vitamin B12 deficiency or other nutrient deficiencies

Treatable healthcare circumstances
Medication Unwanted effects
Early signs of neurodegenerative condition
Typical ageing versions
Hope for Management and Prevention
Regardless if MCI can not be reversed, there are methods to perhaps sluggish progression. The AAN did discover encouraging proof linking training with superior memory in individuals with MCI.
