Effect of socioeconomic status on aphasia severity and recovery.
Low levels of educational attainment and low socioeconomic status have been significantly linked to poor health and increased incidence of disease, including Alzheimer's disease and diseases of the cardiovascular, pulmonary, renal, and gastrointestinal systems. Our goal in the present study was to determine the degree to which educational level and socioeconomic status influence initial severity of aphasia and subsequent recovery. We evaluated the records of 39 persons with aphasia twice: at about 4 months and 103 months postonset. We found early severity of aphasia to be significantly greater for subjects in the lower educational and occupational groups. However, rate of recovery (the slope of the recovery curve) was the same regardless of educational or occupational status.
