Visual stress could be a symptom of Chronic Fatigue Syndrome

University of Leicester research team discovers vision-related abnormalities that could help in diagnosis of illness.
People suffering from Chronic Fatigue Syndrome (CFS) could experience higher levels of visual stress than those without the condition, according to new research from the University of Leicester.
CFS, also known as Myalgic Encephalomyelitis (ME), is a condition that causes persistent exhaustion that affects everyday life and doesn't go away with sleep or rest. Diagnosis of the condition is difficult as its symptoms are similar to other illnesses.
A research team from the University of Leicester led by Dr Claire Hutchinson from the Department of Neuroscience, Psychology and Behaviour has examined patients with and without CFS and has found that those suffering from the condition are more vulnerable to pattern-related visual stress, which causes discomfort and exhaustion when viewing repetitive striped patterns, such as when reading text.
The results of the study, which is published in the journal Perception, could help in the diagnosis of CFS, as the findings suggest that there are visual system abnormalities in people with ME/CFS that may represent an identifiable and easily measurable behavioural marker of the condition.
Dr Hutchinson explained: "Diagnosis of ME/CFS is controversial. With the exception of disabling fatigue, there are few definitive clinical features of the
condition and its core symptoms, overlap with those often prevalent in other conditions. As a result, ME/CFS is often a diagnosis of exclusion, being made as a last resort and possibly after a patient has experienced a series of inappropriate treatments of misdiagnosed disorders.
"It is imperative therefore that research focuses on identifying significant clinical features of CFS/ME with a view to elucidating its underlying pathology and delineating it from other illnesses. Doing so will help researchers and healthcare professionals gain important insights into the condition, aid diagnosis and, in the longer term, inform evidence-based therapeutic interventions."
