* Most dementia patients given anti-psychotics needlessly
* Report could inform clinical practice around the world
* Global dementia cases seen doubling to 66 mln by 2030
More than 140,000 dementia patients in Britain are given anti-psychotic drugs needlessly and overprescribing of the medicines is linked to an extra 1,800 deaths in elderly people each year, a report said on Thursday.
The government-backed review showed that only around 36,000 of around 180,000 dementia patients prescribed anti-psychotics got any benefit from them -- findings it said could affect clinical practice in dementia across the world.
"Anti-psychotics are used too often in dementia," Sube Banerjee, the report's author and a professor of mental health and ageing at the Institute of Psychiatry at King's College London, said in a statement.
He said use of anti-psychotics drugs for dementia should be cut to a third of current levels in Britain and said his study would "provide international leadership in this complex clinical area."
Alzheimer's Disease International predicted in September that more than 35 million people around the world will suffer from dementia in 2010. That number is expected to almost double every 20 years, to 66 million in 2030 and more than 115 million in 2050. [ID:nN20262573]
