Abstract

Several diagnostic symptoms of the visual-processing deficit Meares-Irlen/Visual Stress Syndrome are remarkably similar to symptom manifestations reported by individuals with chronic fatigue syndrome (CFS). We surveyed the specific incidences of nine widely-recognised symptoms of visual stress (VS) in a group of subjects (n=20) previously diagnosed with CFS. The presence of each symptom of VS in the CFS group was compared to its respective presence in both an age and sex matched healthy comparison group (n=46), and an age and sex matched group comprised of individuals (n=14) diagnosed with VS. Results showed the frequencies of all nine VS symptoms in the CFS-diagnosed group to be significantly higher (p=.032 – p<.0005) than in the comparison group, with only two symptoms being statistically less frequent in the CFS group than in the VS-diagnosed group. The average number of VS symptoms reported by the CFS group was also significantly higher than the comparison group, yet not significantly different from the VS group. Thus, the occurrence of VS symptoms in subjects diagnosed with CFS appears to be far greater than previously reported, which in turn may indicate the interplay of some yet to be identified underlying factor(s) common to both conditions.

Resumen

Algunos síntomas del Síndrome de Estrés Visual/Meares-Irlen son similares a los informados por individuos con síndrome de fatiga crónica (SFC). Se evaluó la incidencia de nueve síntomas ampliamente reconocidos de estrés visual (EV) en un grupo de sujetos (n=20) con síndrome de fatiga crónica. La presencia de cada síntoma de EV en el grupo con SFC se comparó con un grupo control de sujetos sanos (n=46) y con un grupo de individuos (n=14) con diagnóstico de EV, equiparables en sexo y edad. Los resultados mostraron una frecuencia en los nueve síntomas de EV en el grupo diagnosticado SFC significativamente mayor (p=0,032-p<0,0005) que en el grupo de comparación, con sólo dos síntomas estadísticamente menos frecuentes en el grupo SFC que en el grupo EV. El número medio de síntomas EV señalados por el grupo SFC también fue significativamente mayor que el del grupo de comparación, aunque no significati vamente diferente el grupo EV. Por lo tanto, la presencia de los síntomas de EV en sujetos con diagnóstico de SFC parece ser mucho mayor que la informada, lo que puede indicar la interacción de algún factor/s subyacente/s aún no identificado/s comunes a ambas condiciones.
