Lithium helps slow the progression of memory loss, raising the possibility it could be used to prevent dementia.
It has long been prescribed to treat mood swings and bipolar disorder, and research shows it can halt the advance of motor neurone disease.
Lithium compounds occur naturally and, unlike newer medicines, are not under patent which means they are more readily available for use.
A study of elderly people found that those who took lithium pills had much better memories after a year than others given a placebo.
Dr Orestes Forlenza, of Sao Paulo University in Brazil, said: “We found that lithium treatment reduced people’s cognitive decline.
“The people who received it for a year performed better on the memory and attention tasks than those who had taken the placebo.”
Although all the participants experienced a decline in their memory and cognitive functioning, this was significantly smaller in the group treated with lithium – which costs only 2.4p per 200 milligram tablet.
The treatment was also linked to a significant decrease in damaging brain fluid proteins known as tau, which are one of the hallmarks of Alzheimer’s. Read more: express.co.uk
