What is Mild cognitive impairment?

Mild cognitive impairment is a decline in memory or thinking that is noticeable and measurable but not severe enough to interfere with daily life.

It sits between normal ageing and dementia. Some people with MCI go on to develop dementia, some stay stable, and a few improve, particularly where the cause is medication, depression or sleep.

It is diagnosed by a clinician after testing, and it is a reason to be assessed rather than a reason to panic.

Why it matters

MCI is the stage at which powers of attorney, care preferences and finances are easiest to sort out.
