Glossary of Elder Care Terms — The Words You'll Hear and What They Mean

When you step into the role of supporting an aging parent or older relative, you'll quickly discover that doctors, nurses, social workers, and insurance representatives use a language all their own. Medical offices, hospital hallways, and insurance paperwork are filled with acronyms and terms that can feel completely foreign. You'll hear words like "comorbidity" and "prior authorization" and wonder if everyone else just knows what these mean by instinct. They don't. These are the terms people learn by necessity, often in the middle of a stressful situation.

This glossary exists so you don't have to ask someone to explain a term three times before you feel confident you understand it. You'll find yourself in conversations where you need to know the difference between Medicare and Medicaid, or understand why a doctor keeps talking about palliative care versus hospice. These aren't small distinctions—they affect decisions about care, costs, and your parent's quality of life. Understanding the language helps you advocate more effectively for your older relative and make better-informed decisions about their care.

The terms below are organized by category to make them easier to find. When you hear one of these words, come back to this list. You're not behind for not knowing these things already.

Medical Terms You'll Hear in Doctor's Offices and Hospital Settings

Dementia is a decline in mental ability that affects memory, thinking, and the ability to perform daily tasks. It's not a specific disease but rather a group of symptoms caused by conditions like Alzheimer's disease or stroke. Unlike normal aging, dementia interferes significantly with daily functioning. It develops gradually and gets worse over time. You might notice your parent forgetting recent conversations, getting lost in familiar places, or struggling to manage finances. Dementia isn't something that happens to everyone as they age, and it's worth taking seriously when someone shows these signs.

Delirium is a confused mental state that comes on suddenly, often within hours or a day. Unlike dementia, delirium is usually temporary and caused by something specific like infection, medication, low blood sugar, or sleep deprivation. A person with delirium might be disoriented, agitated, or unusually drowsy. It's an important distinction because while dementia is a long-term condition, delirium often improves once the underlying cause is treated. When an older person suddenly becomes confused during a hospital stay or after starting a new medication, delirium is often the culprit.

Comorbidity simply means having two or more chronic conditions at the same time. Your parent might have both diabetes and high blood pressure, for example. This is important because these conditions often interact with each other and with medications, making treatment more complex. It's why a doctor treating your parent's heart condition needs to know about their arthritis and kidney issues—everything connects. Understanding your parent's comorbidities helps you see why they might be taking multiple medications and why management can feel complicated.

Palliative care focuses on relieving pain and symptoms, maintaining comfort, and improving quality of life,even while pursuing curative treatment. A person receiving palliative care can still be undergoing chemotherapy or other aggressive treatments. The goal is to make sure that while treating the disease, the person feels as good as possible. This care can happen at any stage of serious illness, not just at the end of life. Palliative care teams often include doctors, nurses, social workers, and specialists focused on symptom management.

Hospice is a specific type of end-of-life care focused entirely on comfort when curative treatment is no longer the goal. Typically, hospice is pursued when someone has a terminal diagnosis and fewer than six months to live. It emphasizes pain management, emotional support, and spiritual care. Hospice teams work to help someone die peacefully and with dignity, and they support the family through the process. Hospice is not giving up on your parent; it's shifting the focus from prolonging life to ensuring the time left is as comfortable and meaningful as possible.

Insurance Terms That Will Come Up Repeatedly

Deductible is the amount of money your parent has to pay out of pocket each year before insurance coverage kicks in. If the deductible is $1,500, your parent pays the first $1,500 of health care costs. After that, insurance starts sharing the cost. Deductibles reset each year. Some plans have lower deductibles (you pay less before coverage starts) and higher copays (you pay more for each visit). Other plans do the opposite, trading lower premiums for higher deductibles.

Copay is a fixed amount your parent pays for a specific service,say $15 for a doctor visit or $50 for an emergency room visit. It's the same amount every time for that service. Copays are usually paid at the time of service. They don't count toward the deductible; they're separate costs.

Coinsurance is different from a copay. After the deductible is met, coinsurance is the percentage of costs that your parent pays while insurance pays the rest. For example, your parent might pay 20% and insurance pays 80%. This continues until the out-of-pocket maximum is reached.

Prior authorization is permission your parent needs from the insurance company before a treatment or service is covered. The doctor's office usually handles requesting this, but sometimes you'll need to follow up to make sure it was approved. Without prior authorization, the insurance company might refuse to pay, leaving your parent responsible for the full cost. It can slow down treatment, which is frustrating, but it's an important step to verify coverage.

Out-of-pocket maximum is the most money your parent will have to pay in a year for covered health care services. This includes deductibles, copays, and coinsurance. Once this maximum is reached, insurance covers 100% of remaining covered services for the rest of that year. This is an important number to know because it gives you a ceiling on what you might spend.

Care Settings Have Different Meanings and Different Levels of Care

Assisted living is a residential setting where older adults live in private or shared apartments but have access to help with daily activities like bathing, dressing, and medication management. They can still manage many things independently. Meals are typically provided in a communal dining room. Assisted living is not a medical facility, though staff are trained in personal care. It works well for people who need some help but don't require skilled nursing care.

Skilled nursing facility (sometimes called a nursing home or SNF) provides medical care supervised by nurses. A doctor oversees care, and nurses administer medications and treatments. These facilities work for people recovering from surgery or hospitalization who need medical supervision but not full hospital-level care. Some people stay short-term for rehabilitation; others live there permanently.

Memory care is a specialized type of assisted living or skilled nursing designed specifically for people with dementia or Alzheimer's disease. Rooms are often less institutional in appearance, staff are trained in dementia care, and the environment is designed to be calming and to prevent wandering. These communities understand the specific challenges of caring for someone with memory loss.

Independent living communities are residential settings for older adults who don't need help with daily care but want community, activities, and support services nearby. Many independent living communities serve people in their 70s and 80s who are still quite active and want social engagement and convenient services in one place.

Financial Terms Related to Government Benefits

Medicare is a federal insurance program for people age 65 and older (and some younger people with disabilities or specific conditions). It covers hospital care, doctor visits, and some preventive services. Medicare has different parts,Part A covers hospital care, Part B covers doctor visits, Part D covers prescription drugs. It's funded through payroll taxes, and eligibility is based on age and work history, not income.

Medicaid is a joint federal and state program that helps low-income individuals and families pay for health care. Unlike Medicare, Medicaid is income-based, and eligibility and coverage vary significantly by state. Medicaid can cover nursing home care and long-term services, which Medicare generally does not cover. This is an important distinction when planning long-term care for someone with limited resources.

Supplemental Security Income (SSI) is a federal program that provides monthly cash assistance to people with limited income and resources who are age 65 or older, or blind, or have disabilities. Unlike Social Security, which is based on work history, SSI is based on need. The amount is modest,designed to provide basic living expenses,but it can be a critical resource for older adults with no savings.
