Uncomplicated Dementia Pathway - Mild Cognitive Impairment
Mild cognitive impairment is a "grey area" between normal age-related memory loss and dementia, and is defined as objectively impaired neuropsychological test performance but intact activities of daily living.
- Most people are able to maintain their cognitive ability at a functioning level throughout their life.
- Approximately 20% of people aged over 65 years have mild cognitive impairment.
- For some people, mild cognitive impairment is a precursor to dementia. A recent meta-analysis reported that the annual conversion rate from mild cognitive impairment to dementia is approximately 5-10%. Many people with mild cognitive impairment however did not progress to dementia even with ten years follow up.
- Between 3-11% of people aged over 65 years and around 33% of people aged over 85 years have dementia.
NB: Cognitive Enhancing Medication (e.g Donezepil) is not indicated in mild cognitive impairment, and maybe potentially harmful.
Any patient in whom there is a concern regarding their cognition a Montreal Cognitive Assessment (MoCA) assessment should be performed. A final total MoCA score of 26 and above is considered normal.
