"Overview of Assisted Living Report" from 2010 stated that 54 percent of assisted living residents are 85 years or older; 27 percent are 75–84 years old; 9 percent of residents are between 65 and 74 years; and 11 percent are younger than 65 years old. 74% of assisted living residents are female; 26 percent are male. Special needs The residence may assist in arranging the appropriate medical, health, and dental care services for each resident. The resident generally chooses his or her medical doctor and dental services. Residents who have periods of temporary incapacity due to illness, injury, or recuperation from surgery often choose assisted living as a supportive option to help them recover quickly so they can return home. In the case of these short-term respite stays, assisted living residences act as the bridge between hospital and home. Short-term respite stays in assisted living are also an option for families when the primary caregiver goes out of town or is otherwise unable to provide the needed care. More recently built facilities are designed with an emphasis on ease of use for disabled people. Bathrooms and kitchens are designed with wheelchairs and walkers in mind. Hallways and doors are extra-wide to accommodate wheelchairs. These facilities are by necessity fully compliant with the Americans with Disabilities Act of 1990 (ADA) or similar legislation elsewhere. The socialization aspects of ALFs are very beneficial to the occupants. Normally the facility has many activities scheduled for the occupants, keeping in mind different disabilities and needs. Locked units Many ALFs also serve the needs of people with some form of dementia including Alzheimer's disease and others with mental disabilities, as long as they do not present an imminent danger to themselves or others. The sections of the building where these residents live are often referred to as memory care. In the United States, legislation enacted by each state defines not only the level of care, but often what conditions are prohibited from being cared for in such a home. In California, these units are not "locked" they are secured by alarms, delays, keypads needing a code, etc. However, they are not locked units like a psychiatric ward. Many ALFs will work to accommodate a person with severe forms of Alzheimer's by having separate private units. These specialized care areas are part of the main building but are secured so residents with Alzheimer's cannot leave and
