Dr. Camilla Clark, of the University College London, interviewed parents and friends of 48 patients with frontotemporal dementia, dementia manifested by a gradual change in the nature of “good manners” notes The Guardian . Condition: they had to know the last 15 years before the disease develops. Dr. Clark protocol was to assess whether or not cynical or totally absurd jokes could be regarded as symptoms of impending dementia. Of those surveyed, many noted that the sense of humor of their relatives had indeed changed over the years.

Patients were observed trying to watch comedies schoolboy good child, such as those of Mr Bean, and displaced more films like Monty Python. Demented patients were much more likely to prefer the humor of Monty Python as other subjects of the same age in good health, says the English site The Independent.

Changes in behavior observed (sometimes up to nine years before the diagnosis) were manifested, according to the relatives of patients with a heightened cynicism and laughter in tragic circumstances. Dr. Clark even notice that this inappropriate humor sometimes borders on bad taste, “like the man who laughed while his wife was scalded.” Another guffawed at the announcement of a natural disaster or the sight of a badly parked car. “ I have asthma, and sometimes laughs when I have trouble breathing,” further evidence that parent.

This study reinforces the idea that in addition to the memory loss that comes first to mind, there are indeed many other symptoms of dementia that affect the daily lives of sufferers. According to the WHO, 47.5 million people are victims of dementia in the world.
