Bottom Line: Sure, cognitive impairment can certainly manifest devoid of dementia. Gentle cognitive impairment (MCI) signifies a middle floor in between usual growing older and dementia, and many treatable ailments may cause cognitive indications which might be completely reversible.
Comprehension the Spectrum
Cognitive function exists on the spectrum from usual getting older to significant dementia. Moderate cognitive impairment (MCI) is actually a dysfunction involving issues with memory along with other psychological capabilities which are increased than ordinary age-associated alterations although not as sizeable because the decrease witnessed which has a dementia.

A lot of cognitive issues don't have anything to perform with dementia and can be absolutely treatable. A examine in the Journal of Dementia & Neuropsychologia observed that nearly twenty% of cognitive Problems may have reversible will cause, which means they can be addressed.
Prevalent reversible will cause involve:

Thyroid, kidney or liver troubles
Sleep apnea and other rest disorders
Vitamin B12 deficiency or other nutrient deficiencies
An an infection, like a urinary tract infection (UTI)
