“…Studies on number reading have shown contradictory results, with 1 study showing that PD affects only word reading and not number reading, 8 whereas another showed that saccadic reading assessed with number reading instead of words is impaired in PD even when the semantic context is absent 24 . A study on reading performance in PD with the use of the Alouette test has also shown that PD patients read fewer words per minute 25 . The Alouette test comprises common words put together in a way that lacks meaning and therefore reduces predictability related to the reader's previous experience.…”

“… 24 A study on reading performance in PD with the use of the Alouette test has also shown that PD patients read fewer words per minute. 25 The Alouette test comprises common words put together in a way that lacks meaning and therefore reduces predictability related to the reader's previous experience. These findings indicate that language and sentence comprehension alone cannot entirely explain the differences in reading performance between PD patients and HCs.…”

Background Reading difficulties are commonly reported in Parkinson's disease (PD). So far, only a few studies have assessed reading in PD, most of them confirming a different pattern in patients compared with healthy populations. Impaired oculomotor control is an early feature of PD. Cognitive deficits, on the other hand, may appear early, but they are most prominent at later stages. Although these two factors are thought to be responsible for the alterations in reading performance, it is unclear how each factor contributes to them. Objectives To evaluate eye movements during reading in PD and healthy controls (HCs). Methods Data from 42 HCs (36% men) and 48 patients with PD (67% men) at Hoehn and Yahr stages ≤3 were analyzed. PD participants were further divided into 2 groups based on their Montreal Cognitive Assessment (MoCA) score using a cutoff of ≥26. Eye movements were recorded with Tobii Pro Spectrum, a screen‐based eye tracker with a sampling rate of 1200 Hz. Results PD participants performed fewer fixations per second (P = 0.033), with a longer mean (P = 0.037) and standard deviation fixation duration (P = 0.033) than HC, and further analysis showed that only patients with a lower MoCA score performed worse than HCs. Reading parameters were weakly associated with MoCA scores, irrespective of age and education. Conclusion Changes in the reading pattern of PD patients are probably attributed to cognitive rather than pure oculomotor alterations.
