Medical professionals have cautioned that a recent study linking Hormone Replacement Therapy (HRT) with dementia has "fundamental limitations".
The Danish study, published in the British Medical Journal, involved more than 60,000 women aged over 60, from 2000 to 2018.
Those using the drug containing both oestrogen and progestin hormones were 24 per cent more likely to go on to be diagnosed with the debilitating condition.
