Inclusion criteria

Inclusion criteria: All participants must meet the following criteria in order to be eligible to participate in this study: - Age between 18 and 90 years; - Dutch speaking., Additional inclusion criteria patient population: - Stroke patients are eligible if they had ischemic stroke. The diagnosis of stroke will be made by an experienced neurologist based on the presence of an acute focal deficit and/or an associated lesion on computed tomography (CT) or magnetic resonance imaging (MRI); - Patients with demonstrable or subjective visual impairments due to suspected brain damage (e.g. tumours, head injury) are also eligible.

Exclusion criteria

Exclusion criteria: A potential subject who meets any of the following criteria will be excluded from participation in this study: - History of alcohol or drug abuse; - Psychiatric disorders which could affect / have affected cognitive function; - Neurological history (exception: for the patient population a history of previous stroke is not an exclusion criterion); - Any other non-neurological disorder influencing cognitive functioning; - Pre-existent cognitive decline as defined by a score of 3.6 or higher on the short Informant Questionnaire on Cognitive Decline in the Elderly-IQCODE Dutch version); - Pre-existent dependency in activities of daily living., Additional exclusion criteria patient population: - Inability to be examined post-stroke due to severe disturbances in consciousness or inability to comprehend task instructions; - Contra-indication for MRI scanning.

Design outcomes

Primary

MeasureTime frame
Performance on experimental computerised tests of specific visual abilities and associated lesion characteristics.

Secondary

MeasureTime frame
- Performance on post-hoc tests of individual patients who show selective visual impairments to address hypotheses derived from the Goodale & Milner model and contrast them with predictions based on the patchwork model. - Performance on neuropsychological tests that tap into different cognitive abilities such as memory or attention.
