Dementia symptoms include memory loss, confusion and difficulty following a conversation.
About 850,000 people in the UK have dementia, according to the Alzheimer’s Society.
There’s currently no cure for the condition, but some treatments and lifestyle changes could help to slow down its progress.
Eating more sodium-rich foods could lower your risk of dementia, scientists have now claimed.
Low sodium levels in patients’ blood could increase their risk of developing dementia, according to US researchers.
Hyponatremia – low sodium-blood levels – was linked to a decline in cognitive function as patients aged.
Men with lower amounts of sodium were 30 per cent more likely to develop cognitive impairment, the scientists said.
They were also 37 per cent more likely to suffer from cognitive decline over time.
“Slightly lower sodium levels in the blood are likely to be unnoticed in clinical practice,” said researcher Dr Kristen Nowak.
“Because both slightly lower serum sodium levels and mild changes in cognitive function are common occurrences with advancing age, future research on this topic is important – including determining whether correcting lower sodium levels affects cognitive function.”
Foods rich in sodium include bacon, salami, olives, pickles and ham.
Hyponatremia symptoms include nausea, vomiting, tiredness, seizures and muscle spasms.
But, eating too much sodium-rich foods could have life-threatening consequences.
Eating too much sodium increases the risk of high blood pressure.
The condition could lead to heart attacks, heart disease and strokes.
Kidney disease could also be caused by eating too many sodium-rich foods.
