‘Senior moments are not a sign of dementia’

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 found that people with dementia tend to lose awareness of memory problems two to three years before the condition develops.

US lead researcher Dr Robert Wilson, from Rush University Medical Centre in Chicago, said: “Our findings suggest that unawareness of one’s memory problems is an inevitable feature of late-life dementia, driven by a build-up of dementia-related changes in the brain.

“Lack of awareness of memory loss is common in dementia, but we haven’t known much about how common it is, when it develops or why some people seem more affected than others. Most studies of memory unawareness in dementia have focused on people who have already been diagnosed.

In contrast, this new study began following older adults before they showed signs of dementia.”

The team tracked the progress of more than 2,000 older individuals with an average age of 76 who were free of dementia at the start of the study. Over 10 years, they were given annual tests of memory and thinking ability.

Participants were also asked how often they had trouble remembering things, and to rate their memory.

For the volunteers diagnosed with dementia, memory awareness began to drop sharply an average of 2.6 years before they developed symptoms.
