Translated title:
Pedestrian's behavior with mild Alzheimer Disease or Mild Cognitive Impairment and how could it be predicted by neuropsychological measures
Summary:
Objective: The aim of the current study was to investigate if the neuropsychological tests examining attentional, executive and visuospatial abilities could be a predictive factor of the pedestrian behavior of patients with mild Alzheimer Disease or Mild Cognitive Impairment as well as to explore how these patients behave as pedestrians (velocity, orientation, crossing in junctions) in contrast to cognitive intact elderly.
Method: Fifteen participants with mild AD, 15 patients with MCI and 15 healthy elderly pedestrian were asked to take a short walking trip outside of the University General Hospital ‘’Attikon’’ in Greece, allowing recording their behavior in real – life traffic conditions. They also underwent a neuropsychological evaluation.
Results: According to the applied One – Way ANOVA analysis the three groups differ significantly in the variables of orientation and velocity, but they did not differ in crossing behavior. AD patients presented to be more disorientated and slower in contrast with MCI patients and healthy elderly. Finally, attentional, executive and visuospatial functions were more strongly associated with crossing decisions in junctions and walking speed than with the orientation ability.
Conclusion: Our findings suggest that neuropsychological tests measuring attention, executive and visuospatial abilities seem to play a more important role in prediction of pedestrian behavior of AD and MCI patients, especially in crossing and walking speed.
