The Cognitively Impaired Elderly: Differential Diagnosis

  • Carl Eisdorfer
  • Donna Cohen


The dramatic changes in the age structure of the U.S. population and the rest of the world over the past 150 years have profound significance for mankind. The aged, who have become one of the fastest growing components of the population, are at an increasing risk for medical and psychiatric diseases. Comprising as they do 10% of the population, the aged account for 30% of the health care costs in the United States. They account for 14% of the outpatient visits to health care facilities and they are admitted to general hospitals 2.5 times the rate of young adults. Older persons occupy 90% of the approximately 1.2 million long term care facility beds, and there are estimates of millions more in the community who could benefit from appropriate care.
