Many dementia patients also suffer from depression and drugs known as selective serotonin uptake inhibitors (SSRIs) are frequently prescribed.

But the British Journal of Clinical Pharmacology reports that the risk of injuries from falls was tripled.

The Alzheimer's Society called for more research into alternative treatments.

The risk of falls following treatment with older anti-depressants is well established, as the medication can cause side effects such as dizziness and unsteadiness.

It had been hoped that a move to newer SSRI-type drugs would reduce this problems, but the latest research, from the Erasmus University Medical Center in Rotterdam, appears to show the reverse.
