Summary
Acute stroke patients with spatial neglect show significant eye deviation towards the right. Measuring eye-in-head position on early brain scans may help diagnose this condition, independent of lesion size.
Area of Science:
- Neurology
- Neuroscience
- Clinical Diagnostics
Background:
- Conjugate eye deviation is a horizontal eye turn in acute stroke patients.
- Spatial neglect is a common neurological disorder following stroke.
- Early diagnosis of spatial neglect is crucial for effective treatment.
Purpose of the Study:
- To investigate the relationship between eye-in-head position on admission brain scans and spatial neglect in acute stroke patients.
- To determine if eye deviation is associated with spatial neglect or lesion size.
Main Methods:
- Analysis of 124 stroke patients admitted consecutively.
- Measurement of horizontal eye-in-head deviation on MRI or CT scans.
- Statistical control for lesion volume as a covariate.
Main Results:
- Horizontal eye-in-head deviation was significantly associated with spatial neglect.
- Patients with spatial neglect exhibited eye deviation towards the ipsilesional right.
- This association was independent of overall lesion volume.
Conclusions:
- Eye-in-head position on clinical brain scans can be a useful indicator of spatial neglect in acute stroke.
- This method may aid in the early diagnosis of spatial neglect, especially in the initial stroke period.

01:12Visual Agnosia
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...
01:24Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
