Artists put brain disease on show in the frame

Some of the most famous artists in history may have left subtle clues to brain disease in their work, scientists have found.

Artists put brain disease on show in the frame

New analysis of the brushstrokes of the likes of Salvador Dali and Pablo Picasso is shining a light on how degenerative illnesses can be spotted years before other life-changing symptoms come to the fore.

Experts at Maynooth and Liverpool universities believe the insights may lead to research that could ultimately help diagnose the early stages of Alzheimer’s and Parkinson’s.

Some 2,092 paintings by seven artists were digitally stripped to black and white in a bid to uncover changing patterns and structures in the works.

Ronan Reilly, from the Department of Computer Science at Maynooth University, ran tests using non-traditional mathematics, similar to those used to study snowflakes, or to spot forged artworks attributed to the renowned abstract expressionist Jackson Pollock.

“Identifying changes in someone’s behaviour that can predict clinical diagnoses years later is very challenging,” said Prof Reilly.

“However, this data suggests that it could be possible to identify changes in the structure of a painting many years before the diagnosis of a neurological disorder.”

The work of Dali and Norval Morrisseau, who are believed to have had Parkinson’s, and James Brooks and Willem De Kooning, who had Alzheimer’s, was analysed alongside paintings by Picasso, Marc Chagall and Claude Monet, who suffered no degenerative brain illness.

The decoding revealed the artistic structures used by those with brain disease changed as they got older, becoming less complex.

Scientists believe the discovery is similar to the way the deteriorating health of a politician or writer can be spotted, as was the case with US president Ronald Reagan years before he was diagnosed with Alzheimer’s.

The research, published in the Neuropsychology journal, found no simplification in patterns and structures used by artists who aged without degenerative brain disease.

Dr Alex Forsythe, from the University of Liverpool’s School of Psychology, said: “Art has long been embraced by psychologists as an effective method of improving the quality of life for those persons living with cognitive disorders.

“We have built on this tradition by unpicking artists’ ‘handwriting’ through the analysis of their individual connection with the brush and paint. This process offers the potential for the detection of emerging neurological problems.”
