Please don't desert family members with dementia - they need us and we need them
"A survey found that 42% of the public think there is no point in keeping up contact at this stage.
But the Alzheimer's Society said family visits stimulated feelings of happiness, comfort and security.
Even as the condition progresses, it said people with dementia can still hold an "emotional memory".
This means they continue to feel happy long after a visit or experience that they may have forgotten."
