Dementia is a term used to describe a decline in cognitive function that affects a person’s daily life. It is a common condition among older adults, but it can also occur in younger individuals. When dementia occurs in individuals under the age of 65, it is known as early-onset dementia.

In this article, we will explore what early-onset dementia is, its causes, and its symptoms.

What is Early-Onset Dementia?

Early-onset dementia is a form of dementia that affects individuals under the age of 65. It is estimated that around 5% of all dementia cases are early-onset. This condition is often misdiagnosed or overlooked because it is not commonly associated with younger individuals.

Early-onset dementia can have a significant impact on a person’s life, as it can affect their ability to work, care for themselves, and maintain relationships. It is important to understand the causes and symptoms of this condition to seek proper treatment and support.

Causes of Early-Onset Dementia

The causes of early-onset dementia are similar to those of dementia in older adults. The most common cause is Alzheimer’s disease, which accounts for around 50% of all dementia cases. Other causes include:

  • Vascular dementia: This type of dementia is caused by reduced blood flow to the brain, often due to a stroke or other cardiovascular issues.
  • Frontotemporal dementia: This type of dementia affects the frontal and temporal lobes of the brain, leading to changes in behavior and personality.
  • Lewy body dementia: This type of dementia is caused by abnormal protein deposits in the brain, leading to cognitive and movement issues.
  • Traumatic brain injury: A severe head injury can increase the risk of developing dementia later in life.

In some cases, early-onset dementia may be caused by genetic factors. For example, individuals with a family history of Alzheimer’s disease may be more likely to develop the condition at a younger age.

Symptoms of Early-Onset Dementia

The symptoms of early-onset dementia are similar to those of dementia in older adults. However, they may present differently in younger individuals. Some common symptoms include:

  • Memory loss: This is often the first and most noticeable symptom of dementia. Individuals may have difficulty remembering recent events or important information.
  • Difficulty with daily tasks: As dementia progresses, individuals may struggle with tasks that were once easy for them, such as cooking, cleaning, or managing finances.
  • Changes in behavior and personality: Dementia can cause changes in mood, behavior, and personality. Individuals may become more irritable, agitated, or withdrawn.
  • Difficulty with language: As dementia affects the brain, individuals may have trouble finding the right words or understanding what others are saying.
  • Confusion and disorientation: Individuals with early-onset dementia may become confused about their surroundings or have difficulty recognizing familiar places.
  • Difficulty with motor skills: As dementia progresses, individuals may have trouble with coordination and movement.

It is important to note that these symptoms may vary from person to person and may not all be present in every case of early-onset dementia.

Seeking Support and Treatment

If you or a loved one is experiencing symptoms of early-onset dementia, it is important to seek support and treatment as soon as possible. Early diagnosis and treatment can help slow the progression of the condition and improve quality of life.

The first step is to consult with a doctor who specializes in dementia and can properly diagnose the condition. They may conduct cognitive tests, brain imaging, and blood tests to determine the cause of the symptoms.

Once a diagnosis is made, there are various treatment options available, including medication, therapy, and lifestyle changes. It is also important to seek support from family, friends, and support groups to help cope with the challenges of living with early-onset dementia.

Dementia Awareness and Education

Dementia is a complex condition that can have a significant impact on individuals and their families. It is important to raise awareness and educate others about the causes, symptoms, and treatment options for dementia, including early-onset dementia.

Understanding Alzheimer’s Disease

Alzheimer’s disease is the most common cause of dementia, accounting for around 60-80% of all cases. It is a progressive brain disorder that affects memory, thinking, and behavior. While it is most commonly associated with older adults, it can also occur in younger individuals.

There is currently no cure for Alzheimer’s disease, but there are treatments available that can help manage symptoms and improve quality of life.

Supporting Dementia Research

Research is crucial in understanding and finding a cure for dementia. Organizations such as the Alzheimer’s Association and the Dementia Society of America are dedicated to funding research and providing support for individuals and families affected by dementia.

By supporting these organizations and participating in events such as the Walk to End Alzheimer’s, we can help raise awareness and funds for dementia research.


Understanding early-onset dementia, a condition that affects individuals under the age of 65, is crucial, especially in the context of assisted living for dementia patients. This condition can profoundly impact their lives, necessitating specialized care and support. It is imperative to comprehend the causes and symptoms, enabling timely intervention and appropriate assistance. 

By fostering awareness and contributing to dementia research, we can collectively strive toward finding a cure for this intricate and devastating condition. Let’s persist in educating ourselves and others about dementia, extending our support to those affected, particularly within the realm of assisted living for dementia patients, where tailored care and understanding are paramount.
