Treatable clinical ailments
Medication side effects
Early indications of neurodegenerative sickness
Standard ageing variations
Hope for Administration and Avoidance
Even if MCI can not be reversed, there are ways to probably sluggish progression. The AAN did discover encouraging proof linking training with improved memory in individuals with MCI.

Investigation indicates that maintaining balanced Life style behavior—such as frequent work out, excellent nutrition, social engagement, and psychological stimulation—might assistance delay or prevent development to dementia.
