Autonomy defines the ability of a person to carry out the actions of daily life. The loss of autonomy leads to dependence. It may be observed in cases of invalidity, in the elderly, or individuals suffering from illnesses such as Alzheimer's disease
or Parkinson's disease
. Autonomy encompasses intellectual, cognitive
, and motor abilities. In France, the AGGIR test is a questionnaire that measures the autonomy of an individual and establishes the need for human or material assistance.
