Can Cognitive Impairment Occur Without Dementia?

Bottom Line: Sure, cognitive impairment can definitely manifest with no dementia. Moderate cognitive impairment (MCI) represents a middle floor in between usual getting older and dementia, and several treatable conditions can result in cognitive symptoms which might be wholly reversible.
