Research study demonstrating impact of aphasia on the quality of life for people

Aphasia Has Greater Negative Impact on a Person’s Quality of Life than Cancer or Alzheimer’s Disease.

  • Researchers studied health-related factors affecting quality of life for hospital residents in Ontario, Canada.
  • They examined the impact of 60 different diseases and 15 conditions on quality of life of 66,193 people.
  • Results showed aphasia has the largest negative impact on quality of life, more than cancer and Alzheimer’s disease.
  • The negative effects of aphasia on an individual’s quality of life includes their inability to communicate with and engage their family, friends, doctors and their wider community.
  • Health care providers should act so as to significantly improved services for people with aphasia as people with aphasia frequently cannot express their wants and needs unassisted.
  • The next stage is to ensure that those who have the power to influence the provision of services from health and social systems are fully aware of the impact that aphasia has and the impact that services for aphasic people and their relatives can have when readily provided.
