What Is Dementia?

Dementia is a collection of symptoms resulting from certain brain disorders where two or more functions have significant impairment, such as memory and language skills. Experts believe that many factors contribute to Dementia, and it often presents as a combination of progressive symptoms affecting personality, behavior, memory, language, mood, and motor skills.

What Dementia Is Not

Dementia is not a specific disease; it is a syndrome. Rather, it describes a wide range of medical conditions that affect the brain, including Alzheimer’s disease (AD), Vascular Dementia, Lewy Body Dementia, Frontotemporal Dementia (FTD), Huntington’s disease, and Creutzfeldt-Jakob disease, and more.

Dementia is not characterized by memory loss alone. While it is one of the common symptoms of Dementia, memory loss by itself does indicate Dementia. Healthcare providers may diagnose Dementia if two or more brain functions have significant impairment without loss of consciousness, and there are declines in cognitive performance over time. 

Dementia is not widely considered a “normal” part of aging. While mild changes in cognition are common to experience as people mature, Dementia is different in its ability to cause a severe disruption in daily life and functioning.

While certain conditions can masquerade as Dementia and may be treatable, the pathologies that cause Dementia are not considered curable. While no cure exists for Dementia today, several symptom management techniques are available for consideration, including medications, non-medical therapies, and even alternative medicine.

Types of Dementia

As referenced in this useful Dementia help infographic, the major types of Dementia include:

  • Alzheimer’s disease (AD) – A progressive brain disorder that typically begins slowly destroys short term memory and other mental functions

  • Vascular Dementia (multi-infarct) – The loss of cognitive function caused by multiple mini-strokes

  • Lewy Body Dementia (LBD) – A progressive condition that is sometimes accompanied by hallucinations that may cause a decline in reasoning, mobility (slight tremors, falls), and function due to damaging microscopic deposits on the brain.

  • Frontotemporal Degeneration (FTD) – An umbrella term for brain disorders that affect the nerve cells in the frontal and/or prefrontal lobes, causing the lobes to shrink, which most affects executive functions like decision making.

  • Traumatic Brain Injury (TBI) – A disruption of brain function usually caused by a violent blow, bump, or jolt of the head (concussion).

  • Wernicke-Korsakoff Syndrome (WKS) – A neurological disorder caused by a deficiency in thiamin (vitamin B1).

  • Creutzfeldt-Jakob disease – A rapidly degenerative brain disorder experts believe caused by an abnormal isoform of a cellular glycoprotein called prion protein.

  • Huntington’s disease – A rare and inherited condition that causes a breakdown of the brain’s nerve cells, triggering movement, cognitive, and psychiatric symptoms.

  • Multiple Sclerosis (MS) – A brain and spinal cord disease where the immune system attacks the protective covering of nerves, disrupting communication between the brain and body.

  • AIDS Dementia complex – A loss of mental skills in people with late-stage AIDS affecting thinking, reasoning, learning, understanding, and moving.

  • Chronic Traumatic Encephalopathy (CTE) – A neurodegenerative disease thought to be caused by repeated concussions

The First Stages of Dementia

While initial Dementia symptoms are unique to each person, a few of the early signs can include: 

  • Short term memory loss

  • Normal daily activities become difficult

  • May lose the ability to solve problems

  • May be unable to control emotions

  • Personality changes

  • Agitation

  • Desires to "go home" or leave their house

  • May see things that aren’t there

  • Repeating questions

  • Inability to retrace steps

  • Frequently misplacing items

  • Forgetting the functions of everyday items

  • Difficulty remembering the names of objects or close relatives

As the condition progresses, people living with Dementia may experience personality changes and behavioral challenges, such as delusions and hallucinations. For additional Dementia help, consult your doctor or medical specialist to understand symptoms and behaviors unique to one's specific situation.

How to Help Someone With Dementia

If you’re helping to care for a person living with Dementia, there are many tips and resources to guide your journey. The following are a few helpful suggestions for how to care for someone with Dementia:

  • Learn post-diagnosis steps. Reference the practical steps we outlined in this infographic on Dementia help after diagnosis, including getting a written diagnosis, considering a second opinion, and creating a plan of care.

  • Make it legal. If you are responsible for a loved one’s care, ensure you have the proper legal rights to do so by becoming the designated Power of Attorney (POA) or conservator or guardian.

  • Educate yourself on the diagnosis. Learn as much as you can about the diagnosis to help you understand the person living with Dementia with compassion and empathy. These health information links and brain health resources may also help shed light.

  • Think about the future. Determine the amount and type of long-term care your loved one will need, such as a caregiving service or assisted living facility, and begin researching the options early so that you’re prepared.

  • Reference free online training resources. Look to Dementia help organizations such as the Dementia Society, UCLA, Morningside Ministries, and Johns Hopkins School of Nursing that provide free online videos, education, and training for caregivers of people living with Dementia.


  • Make home safe. Make the home environment Dementia-friendly with simple adjustments to noise levels, lighting, color schemes, labeling, safety measures to prevent accidents, etc.

  • Rely on routines. Develop and adhere to predictable routines to help reduce confusion and frustration.

  • Use technology. Helpful Dementia technologies can bring joy to a person you know, living with Dementia. Browse our award-winning S.M.A.R.T. winners, including SingFit™ for music health, SafeWander device, and Joy for All Companion Pet toys.

  • Communicate with care. When talking to a parent or loved one living with Dementia, use their name to get their attention, offer simple phrasing with short sentences, and take care not to talk to them as a child.

  • Use patience and compassion. Be patient by allowing plenty of time to speak to avoid startling, confusing, or agitating, and avoid correcting things they may not remember correctly.

  • Follow medical advice. Adhere to your loved one’s healthcare provider’s advice for daily exercise and activities, dental care, nutrition, bathing and skincare, and medications.

  • Get a DSA Aware & Share card. Request a complementary Aware & Share Card that you or your loved one can present to people in hotels, restaurants, hospitals, stores, and elsewhere to quietly request extra TLC for communicating with respect and dignity.
