Dementia sufferers ‘stop noticing memory loss two years before condition develops'

US study shows sharp drop in memory awareness about two years before the development of symptoms

Experiencing "senior moments" may be a good sign rather than a cause for concern, research suggests. The time to worry is when you begin to stop noticing memory lapses, scientists have shown.

A study, published in the journal Neurology, found that people with dementia tended to lose awareness of memory problems two to three years before the condition developed.
