The Judgment of Line Orientation test (JLO) is a neuropsychological assessment of basic visuospatial function which requires the participant to match two probe line segments against eleven differently oriented lines. Most examinees perform normally on this assessment in the absence of neurological or psychiatric disease. Impairment on the JLO indicates visuospatial dysfunction which is associated with ischemic and hemorrhagic stroke, Alzheimer’s disease, and Parkinson’s Disease among other debilitating conditions.
