US scientists believe they have uncovered one of the mechanisms that enables the brain to form memories. Synapses - where brain cells connect with each other - have long been known to be the key site of information exchange and storage in the brain. But researchers say they have now learnt how molecules at the site of the synapse behave to cement a memory.

The results showed that as BMI increased, brain volume decreased - a finding that has been reported in other studies. But the findings also showed a closer connection between abdominal fat and the risk of dementia. The link between visceral fat around the central organs and smaller brain volume was independent of overall weight.

A test could indicate whether people in their 40s are more likely to develop dementia later in life, scientists say. But wouldn't many of us rather not know? It is a devastating, heart-breaking, life-shattering condition - and one with an enormous impact not just on those who live with it, but on their loved ones too. Dementia robs from us our memories and our ability to think - the very brain functions that shape our sense of self...
