The present study investigates visuoconstructive performance and hemispatial inattention in schizotypic college students and control subjects using the Rey-Osterrieth Complex Figure Test (CFT). Both copy and delay CFT accuracy, as well as line bisection scores on the CFT, were examined in right-handed males reporting positive schizotypy (deviantly high scorers on the Perceptual Aberration and Magical Ideation Scales; n=24) and those reporting negative schizotypy (deviantly high scorers on the revised Social Anhedonia Scale and Physical Anhedonia Scale; n=26), as well as controls (n=45). The negative schizotypy group displayed reduced visuoconstructive performance, as measured by performance on both the copy and delay trials of the CFT. We did not find a significant relationship between schizotypy and hemispatial inattention. These findings suggest that negative schizotypy may be associated with memory performance deficits, but do not support prior assertions of a relationship between hemispatial inattention and positive schizotypy.

Purpose Of Review: There continue to be a plethora of approaches to the rehabilitation of hemispatial inattention, from different forms of sensory stimulation (visual, auditory and somatosensory feedback), through all major modes of non-invasive brain stimulation to drug therapies. Here we summarise trials published in the years 2017-2022 and tabulate their effect sizes, with the aim of drawing on common themes that may serve to inform future rehabilitative studies.

Recent Findings: Immersive virtual reality approaches to visual stimulation seem well tolerated, although they have yet to yield any clinically relevant improvements.

The Mesulam Cancellation Test is a low cost, quick measure used to screen for hemispatial inattention. The task is also useful for observing a patient's organizational approach. We developed a method to quantify the organizational strategy used by patients in completing this visual scanning task.

Hemispatial inattention (HSI), a lateralised impairment of spatial processing, is a common consequence of stroke. It is a poor prognostic indicator for functional recovery and interferes with the progress during in-patient neurorehabilitation. Dopaminergic medication has shown promise in improving HSI in the chronic post-stroke period but is untested in more acute settings, e.

People with Complex Regional Pain Syndrome (CRPS) following limb injury can show neuropsychological symptoms in the absence of observable brain pathologies. These can include sensory changes, distorted body representation, and inattention to their affected limb and its surrounding space, resembling post-stroke hemispatial neglect. The precise nature and mechanisms of these neuropsychological symptoms are unclear, however insights could be gained by testing for dissociations and associations that have been observed in stroke patients.
