The National Institute on Aging (NIA), one of the 25 institutes and centers of the National Institutes of Health (NIH), leads a broad scientific effort to understand the nature of aging and to extend the healthy, active years of life. Founded in 1974, Congress authorized the creation of the NIA to provide leadership in aging research, training, health information dissemination, and other programs relevant to aging and older people.

The NIA’s mission is to improve the health and well-being of older Americans through research, and specifically to:

  • Support and conduct high quality research on: aging processes, age-related diseases, & special problems and needs of the aged;
  • Train and develop highly skilled research scientists to accelerate research progress;
  • Develop and maintain state-of-the-art resources to accelerate research progress;
  • Disseminate information and communicate with the public and interested groups on health and research advances and on new directions for research.

Programs & Activities
The NIA sponsors research on aging through extramural and intramural programs. The extramural program funds research and training at universities, hospitals, medical centers, and other public & private organizations nationwide. The intramural program conducts basic and clinical research in Baltimore, MD, as well as on the NIH campus in Bethesda, MD.

The NIA and Aphasia
The NIA plays an important role, as its population of study (the aging population) is largely effected with a variety of causes - namely strokes - that can lead to the acquisition of aphasia.
