10 to 15 people per 100,000 residents take their own lives each year. The average is highest amongst pensioners.

Psychologist Fränz D'Onghia of the Luxembourg League for Mental Health explained the reasons for the statistic and how to help prevent it.

A number of risk factors can affect the mental health of the elderly. Illnesses, isolation, loss of family and friends, as well as the loss of autonomy. Many older people lose the ability to drive or even take care of themselves, which sees their mental health plummet.

Age can also affect a number of mental illnesses which are difficult to diagnose, such as depression. D'Onghia explained that classic symptoms of depression, such as difficulty sleeping, or loss of appetite and energy, are common among older people, which means depression can often go undiagnosed in the elderly.

Important signs to look out for are changes in behaviour and daily routine. D'Onghia recommended following up on such signs, or "ruptures", for example when a person stops going out or taking calls.

Preventative measures could take the form of helping the elderly to prepare for loss of autonomy, helping them find alternative methods of transport such as special bus services, or helping them integrate in retirement homes or communities.

Anyone with concerns for older people close to them should speak to their GP for guidance. The RBS centre also has resources, as well as municipalities' social offices. For acute cases, an anonymous report can be made to SOS Détresse on 45 45 45.
