The Different Types of Dementia

Dementia is a neurological disorder that affects a person’s ability to think, remember, and communicate. There are many different types of dementia, each with its distinct set of symptoms. Keep reading to learn more about the different types of dementia and how they are diagnosed.

Understanding Dementia


If a loved one has been diagnosed with dementia, you want to provide them with the best support possible. The first step in creating a supportive environment for someone struggling with dementia is learning about their diagnosis. There are many great resources to help you better understand this dreadful disease, including Alzinfo—a website that provides information about Alzheimer’s disease and other types of dementia.

Dementia is a term for a group of symptoms that affect memory, thinking, and behavior. It is caused by damage to the brain. Dementia may also be called cognitive impairment or memory loss and affects people in different ways. Some people may have trouble remembering things, while others may have trouble reasoning or planning. People with dementia may also experience changes in their mood or behavior.

Dementia is a serious condition that can make it difficult for a person to live independently. Early diagnosis and treatment are important to help preserve quality of life. Keep reading to learn more about the different types of dementia.

Early-Onset Dementia

Early-onset dementia is a type of dementia that affects people under the age of 65. It is caused by damage to the brain that impairs cognitive function, memory, and thinking skills. Early-onset dementia can lead to problems with daily activities such as bathing, dressing, and using the bathroom. In some cases, it can also lead to seizures or mobility issues. There is no known cure for early-onset dementia, but there are treatments available that can help improve quality of life.

Alzheimer’s Disease

Alzheimer’s disease is a progressive form of dementia that worsens over time and affects memory, thinking, and behavior. Alzheimer’s disease is the most common type of dementia, affecting an estimated 5.4 million Americans. It is the sixth leading cause of death in the United States.

Early signs of Alzheimer’s may include difficulty with memory, organizing thoughts, or making decisions. As the disease progresses, people with Alzheimer’s may have difficulty speaking, writing, or completing routine tasks. They may also become confused about time, people, and places.

In the later stages of the disease, people with Alzheimer’s may become agitated, restless, and lose the ability to communicate. They may also experience changes in mood and behavior, such as becoming aggressive, paranoid, or depressed.

Lewy Body Dementia


Lewy body dementia is a type of dementia that is caused by the abnormal build-up of Lewy bodies in the brain. Lewy bodies are clumps of protein that can disrupt normal brain function. This can lead to problems with thinking, movement, and mood.

Symptoms of Lewy body dementia can vary from person to person but can include problems with thinking and memory, visual hallucinations, changes in mood and behavior, trouble moving or speaking, and a decline in physical abilities.

There is no cure for Lewy body dementia, but there are treatments available that can help manage symptoms. Treatment strategies may include medications to treat symptoms such as psychosis or movement disorders, therapies to help with cognitive decline or problem behaviors, and support services to help caregivers manage their loved one’s care.

Frontotemporal Dementia

Frontotemporal dementia (FTD) is a type of dementia that affects the frontal and temporal lobes of the brain. The frontal lobe controls reasoning, planning, problem-solving, emotions, and speech. The temporal lobe controls memory and understanding of language. FTD often causes changes in behavior and personality, such as becoming more impulsive or unruly, or becoming less interested in socializing and taking care of oneself. Memory loss is not usually as severe as it is in other types of dementia.

Dementia can have a significant impact on patients and their families, so it is important to be aware of the different types and their symptoms. If you’re concerned that a loved one may be exhibiting signs and symptoms of dementia, it’s important to schedule an appointment with your health care provider.
