Reversible Causes of Cognitive Impairment

A lot of cognitive problems have nothing to carry out with dementia and may be absolutely treatable. A study while in the Journal of Dementia & Neuropsychologia found that just about twenty% of cognitive Diseases might have reversible will cause, meaning they are often dealt with.

Medical Situations:

Thyroid, kidney or liver challenges
Slumber apnea as well as other rest Conditions

Treatable medical conditions
Medication side effects
Early indications of neurodegenerative sickness
Usual growing old versions
Hope for Management and Prevention

Regardless if MCI can't be reversed, there are ways to possibly slow development. The AAN did uncover encouraging evidence linking exercise with improved memory in those with MCI.

Investigation suggests that protecting healthier Way of life patterns—like normal training, very good nutrition, social engagement, and psychological stimulation—may enable delay or protect against progression to dementia.
