Treatable clinical ailments
Medication Unintended effects
Early indications of neurodegenerative disorder
Usual getting old versions
Hope for Management and Prevention
Even when MCI can not be reversed, there are methods to most likely sluggish progression. The AAN did discover encouraging evidence linking training with improved memory in individuals with MCI.
