Losing interest in hobbies and other activities in older age could be an early sign of dementia, according to scientists.
Apathy in older people suggests a loss of grey matter and offers doctors a new tool with which to identify a group of the population at risk of developing Alzheimer’s disease.
A study showed elderly people who are apathetic but not suffering depression have shrinking amounts of grey and white matter – neurons in the brain that control memory and communication respectively.
