EEG-based assessment of sustained attention in geriatric inpatients: a feasibility study.
Only a minority of referred geriatric inpatients could complete electroencephalography attention testing.
EEG-based assessment of sustained attention in geriatric inpatients: a feasibility study.
Sustained attention is a core cognitive function, frequently declines with age and neurological disease, and is highly relevant for functional outcomes in geriatric populations.
This study evaluated the procedural and methodological feasibility of electroencephalography-based sustained-attention assessments in geriatric inpatients undergoing early rehabilitative geriatric complex treatment (early rehabilitative geriatric complex treatment).
only 43 of 173 referred patients could be enrolled for electroencephalography attention testing
Geriatric participants completed standardized neuropsychological testing and two computerized attention tasks, the Psychomotor Vigilance Task (Psychomotor Vigilance Task) and a cued Go-NoGo task, during 32-channel electroencephalography recording, including a resting-state recording.
Of those, 38 could undergo structured cognitive testing, and resting-state electroencephalography and task-evoked ERPs could be recorded with adequate signal quality However, procedural feasibility was limited by substantial selection and attrition, resulting in incomplete protocol completion.
Overall, resting-state and task electroencephalography measures of sustained attention could be acquired with adequate data quality only in a selected subgroup of geriatric inpatients, who were able to participate in structured cognitive assessments, while extended and repeated assessment protocols were constrained by procedural burden, suggesting that electroencephalography-based follow-up assessments are difficult to implement under current clinical conditions.
