Can paint strokes help identify Alzheimer’s?
A new University of Liverpool study published in 'Neuropsychology!' shows that it may be possible to detect neurodegenerative disorders in artists before they are diagnosed. Psychologist Dr Alex Forsythe from the University's School of Psychology and her team, working with Dr Tamsin Williams of Tees, Esk, and Wear Valleys NHS Trust, Vale of York and Maynooth University, Ireland, examined 2092 paintings from the careers of seven famous artists who experienced both normal ageing and neurodegenerative disorders. Of the seven, two had suffered from Parkinson's disease (Salvador Dali and Norval Morrisseau), two had suffered from Alzheimer's disease (James Brooks and Willem De Kooning) and three had no recorded neurodegenerative disorders (Marc Chagall, Pablo Picasso and Claude Monet). Fractal analyses The brushstrokes of each of the paintings were analysed using a method of applying non-traditional mathematics to patterns known as 'Fractal' analyses to identify complex geometric patterns. Fractals are mathematical characterisations of self-repeating patterns often described as the 'fingerprints of nature'. They can be found in natural phenomena such as clouds, snowflakes, trees, rivers, and mountains. This method has also been used to determine the authenticity of major works of art.
