Memory of road signs in healthy elderly drivers and in patients with MCI or Alzheimer's Disease

Memory of road signs in healthy elderly drivers and in patients with MCI or Alzheimer's Disease

Objective: To investigate the ability of recognition and recall of context of road signs in healthy elderly drivers, drivers with Mild Cognitive Impairment (MCI) and drivers with mild Alzheimer’s disease (AD) and correlate their performance with their neuropsychological battery outcome measures.
Methods: The sample of the present study included 45 individuals; 15 patients with mild Alzheimer’s disease, 15 patients with amnestic Mild Cognitive Impairment and 15 Healthy Controls, from 65 to 85 years of age. Participants were examined in two conditions; (a) in recalling and interpreting the context of 10 common road signs via declarative memory and (b) in identifying 30 road signs with multiple-choice assistance. An evaluation of their cognitive functions was preceded by neuropsychological assessment.
Results: AD group scored worse than the MCI and Control groups in recalling the sequence of correct actions on 10 road sign test, while the MCI group had no significant difference in relation with the Control group. AD group scored worse than the MCI and Control groups in recognizing and matching the sign with the proper sentence, while the MCI group had no significant difference in relation with the Control group. Measures from the neuropsychological battery showed a positive correlation with a visuospatial tool in the MCI group and another correlation for the AD group with an episodic memory tool, both in the 30 road sign condition.
Conclusions: Patients with mild AD perform poorly in recalling the context of road signs or even recognizing them, thus revealing a part of the difficulty that Alzheimer drivers possess and exacerbates the problem of following directions or finding their way. On the other hand, MCI patients seem to be on par with healthy elderly drivers on that matter and any disturbances in their driving competence are not due to road signs.
