Expatriate international health insurance customers may be interested to hear that pain relief can decrease the agitation felt by dementia sufferers.
Professor Clive Ballard from Kings College London said in a BMJ group podcast that he had recently completed research into the use of analgesia for these individuals as part of a randomised controlled trial.
There was "quite a strong outcome", he claimed, with "a very significant improvement in agitation" for the people being supplied with pain relief.
Patients in the other cluster were supplied with analgesics when they required but were not "specifically augmented in this systematic way", Mr Ballard continued.
When the supply of painkillers stopped, the improvements deteriorated, the professor continued.
He called this "a bigger effect than you see with anti-psychotics" although the drug he was supplying in most cases was just paracetamol.
Research into dementia requires a greater amount of funding as scientific enquiry into the problem has reached an "exciting time", media manager at the Alzheimer's Society Hananh Clack recently claimed.
