Bottom Line: Indeed, cognitive impairment can undoubtedly happen with no dementia. Mild cognitive impairment (MCI) signifies a Center ground amongst ordinary growing older and dementia, and a lot of treatable problems can cause cognitive signs which have been totally reversible.
Comprehension the Spectrum
Cognitive functionality exists on a spectrum from typical growing older to intense dementia. Mild cognitive impairment (MCI) is actually a problem involving issues with memory and other mental functions which can be increased than usual age-similar changes but not as substantial because the decrease observed by using a dementia.

The value of Early Analysis
Obtaining a right analysis is very important because these Issues need to be diagnosed as early as feasible to stay away from permanent damage. A comprehensive analysis can identify whether cognitive signs and symptoms are because of:
Treatable healthcare situations
Medication Negative effects
Early signs of neurodegenerative disease
Normal aging variants
Hope for Administration and Avoidance
Even though MCI cannot be reversed, there are ways to likely sluggish progression. The AAN did find encouraging proof linking work out with greater memory in people with MCI.
