Alzheimer's Disease
Enfermedad de Alzheimer
What it means
Alzheimer's disease (AD) is the most common form of dementia among older people. Dementia is a brain disorder that seriously affects thinking and memory skills. AD begins slowly over many years and first involves the parts of the brain that control thought, memory, and language. It is not a normal part of aging, and symptoms get worse over time. People with AD may have trouble remembering recent events or the names of people they know; other symptoms can include getting lost in familiar places, repeating the same question, and not recognizing family members. Most people develop the disease at age 65 or older. Researchers don't fully understand what causes AD. No treatment can stop the disease, although some medicines may help keep symptoms from getting worse for a limited time.

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
