ADT prostate cancer treatment can double chances of dementia, says study


Androgen Deprivation Remedial programme (ADT) shuts down the body’s main supply of the male hormone and is a less potent alternative to physical castration.

It is a standard treatment for men whose cancers sire started to spread and cannot be eliminated by surgery or radiotherapy alone.

But a new burn the midnight oil suggests there may be a serious hidden danger associated with ADT – an rose risk of Alzheimer’s and other forms of dementia.

Scientists who analysed the vigorousness records of more than 9,000 tients found that when men were assumption ADT their chances of having dementia within five years doubled.

In supreme terms, the risk is still small.

Of the 1,829 tients who underwent androgen deprivation, virtuous 7.9 per cent developed dementia.

This com red with 3.5 per cent of the union not treated with ADT.

However, lead researcher Dr Nigam Shah, from Stanford University in the US, said: “The imperil is real, and depending on the prior dementia history of the tient, we may want to ruminate on alternative treatment.”

Men aged 70 and older, and who had been on ADT for at least 12 months, were most at jeo rdize, the study reported in the journal Jama Oncology showed.

The most undistinguished form of ADT used in the UK is a drug called goserelin, sold under the tag name Zoladex, which is injected.

It interferes with signals from the percipience that instruct the testicles to make testosterone.

The scientists urged prostate cancer invalids receiving ADT not to change their treatment without consulting their doctors.

Co-author Dr Kevin Nead, from the University of Pennsylvania, US, suggested: “I was surprised at how ubiquitous the effects on all types of dementia were, but I would for all not alter clinical care based on our results.”

He said more investigating was needed to look at the link between ADT and dementia and identify what understandings of tients might be most at risk.

There are daily changes that can pirate fight memory loss, according to experts.

Male hormones are be informed to play a role in the health and growth of neurons, which may help untangle justify the association, said the scientists.

Another type of treatment blocks the vigour of testosterone on tumours rather than cutting off supplies of the hormone.

There is no urging that taking these drugs, known as anti-androgens, increases the jeo rdize of dementia.
