Fundamentally, a caregiver is someone who provides care to another person or persons in need of assistance.

This can be a nurse, doctor, certified nursing assistant, or family caregiver. Professional in-home caregivers, also known as home care aides, primarily provide assistance with the Activities of Daily Living (daily human functions such as hygiene, eating, bathing, and toileting), these are referred to as ADLs.

Caregivers can provide care just about anywhere including in the home, hospital settings, or assisted living facilities.
