进入姑息和支持治疗病房的患者的语言理解和认知过程评估

PRIMARY OBJECTIVES:

I. To estimate the magnitude of electroencephalography (EEG) response to verbal stimuli among cancer patients in the last days in life admitted to a palliative and supportive care unit (PSCU).

II. To examine the feasibility of conducting EEG in cancer patients in the last days of life.

SECONDARY OBJECTIVES:

I. To compare the magnitude of EEG response between impending death cohort and control cohort.

II. To determine the association between the magnitude of EEG response and clinical assessments (e.g. JFK Coma Recovery Scale-Revised [CRS-R], Glasgow Coma Scale [GCS], Richmond Agitation Sedation Scale [RASS], Memorial Delirium Assessment Scale [MDAS]) in impending death cohort and control cohort separately.

III. To determine the magnitude of EEG response to pressure/noxious stimuli in impending death cohort and control cohort separately.

IV. To examine serial EEG changes in auditory cortex activation and cognitive processing in cancer patients over the last days of life.

OUTLINE:

Patients undergo EEG over 30 minutes daily until death or discharge and complete questionnaires over 30 minutes daily until death or discharge to check level of consciousness, thought, and ability to communicate.
