New research has revealed the impact the timing of taking hormone replacement therapy (HRT) in women has on developing Alzheimer's disease.
The study, published in the journal Neurology online, found that depending on the type of hormones used and the timing of the therapy, there was either an increased or decreased risk of Alzheimer's in the future.
Commenting on the results of the research, Dr Simon Ridley, head of research at Alzheimer's Research UK, called for more studies to be carried out investigating the effect of HRT.
He said: "Any medication may carry a number of potential benefits and drawbacks and anyone who is concerned about hormone replacement therapy should speak to their GP."
Dr Ridley added delaying the onset of Alzheimer's disease by five years could halve the number of people who die with the condition.
TauRx Therapeutics recently announced that it will begin two phase III clinical trials on a drug intended to slow or stop the progression of Alzheimer's.
