Bottom Line: Yes, cognitive impairment can definitely come about with no dementia. Mild cognitive impairment (MCI) signifies a Center ground concerning standard getting older and dementia, and several treatable situations can cause cognitive signs or symptoms which are absolutely reversible.
Comprehending the Spectrum
Cognitive purpose exists on a spectrum from standard aging to extreme dementia. Moderate cognitive impairment (MCI) is really a problem involving issues with memory along with other psychological capabilities that are better than usual age-related adjustments although not as major as the decline witnessed that has a dementia.

In several scenarios, the indicators of MCI may possibly remain exactly the same or even improve.
MCI can often be reversed if a typical wellbeing issue (for example sleep deprivation) is causing the decrease. In Individuals cases, addressing the fundamental result in can dramatically make improvements to cognition.
Forms of MCI Outcomes
Exploration exhibits three doable paths for people with MCI:

Treatable health-related situations
Medication Negative effects
Early signs of neurodegenerative disease
Normal getting old variants
Hope for Administration and Prevention
Even when MCI can not be reversed, there are methods to probably slow development. The AAN did come across encouraging evidence linking physical exercise with better memory in those with MCI. Performing exercises can supply mental and social stimulation though increasing blood circulation towards the Mind, potentially even prompting the release of molecules that maintenance brain cells and create connections concerning them.
Investigation suggests that protecting healthier Way of life patterns—which include normal training, very good nutrition, social engagement, and psychological stimulation—might enable delay or protect against progression to dementia.
