Bottom Line: Sure, cognitive impairment can definitely come about with out dementia. Delicate cognitive impairment (MCI) signifies a middle ground concerning typical getting old and dementia, and lots of treatable disorders could cause cognitive indications which are fully reversible.
Understanding the Spectrum
Cognitive perform exists on a spectrum from regular growing older to intense dementia. Mild cognitive impairment (MCI) is actually a problem involving issues with memory and other mental functions which can be larger than ordinary age-related modifications but not as considerable since the decrease viewed using a dementia.

Reversible Causes of Cognitive Impairment
A lot of cognitive issues don't have anything to do with dementia and may be wholly treatable. A research from the Journal of Dementia & Neuropsychologia discovered that just about twenty% of cognitive disorders could have reversible results in, which means they are often dealt with.
Typical reversible brings about involve:

Thyroid, kidney or liver complications
Sleep apnea along with other snooze Diseases

Treatable healthcare situations
Medication Unwanted effects
Early indications of neurodegenerative ailment
Usual growing old versions
Hope for Management and Prevention
