At What Age Can Dementia Set In?

Dementia is a term for several diseases that can affect the cognitive functions of loved ones. While dementia usually affects older adults 65 years and over, early-onset dementia can occur between the 30s to mid-60s.

Dementia can reshape the responsibilities of caregivers as dementia progresses. Memory care in senior living communities can provide personalized support for loved ones with dementia based on their care needs.

Understanding Dementia

Dementia is not a specific disease but an umbrella term that describes a range of symptoms associated with cognitive decline severe enough to interfere with daily living. It encompasses several conditions, the most common of which is Alzheimer’s disease. Other types of dementia include vascular dementia, Lewy body dementia, and frontotemporal disorders.

Dementia can present differently in individuals. Common problems resulting from dementia can affect:

Memory
Language
Problem-solving
Communication
Attention
Visual perception

Common signs of dementia can include the following:

Getting lost in familiar surroundings
Using unusual words to identify familiar objects
Forgetting the names of family members or friends
Unable to recall old memories
Unable to complete tasks independently

Risk Factors for Dementia

Dementia is not a normal part of aging. However, it does affect mostly older adults. Age is a risk factor for dementia, but other risk factors can include:

Family history: Your risk for dementia increases if you have parents or siblings with dementia
Race/ethnicity: Older African Americans and Hispanics are more likely to develop dementia
Poor heart health: Health conditions such as high blood pressure, high cholesterol, and smoking can increase your risk of dementia
Traumatic brain injury: Head injuries can increase your risk of dementia

Age & Dementia

While age itself is not a cause of dementia, it’s the highest known risk factor. Most people who develop dementia do so after the age of 65, a stage commonly referred to as late-onset dementia. However, dementia can affect individuals younger than this, referred to as early-onset or young-onset dementia.

Early-Onset Dementia

Early-onset dementia is the onset of symptoms before 65 years and accounts for up to 9% of cases. Early-onset Alzheimer’s disease can occur in people between their 30s to mid-60s. While less common, its impact is profound, often arising unexpectedly amidst careers, raising children, or when life expectations are peaking.

Late-Onset Dementia

Conversely, late-onset dementia, caused by Alzheimer’s disease, generally refers to symptoms of dementia that begin after the age of 65. Late-onset dementia presents with progressive decline in memory and other cognitive impairments.

Recognizing Early Signs of Dementia

Identifying dementia in its early stages can be challenging. Short-term memory loss, difficulty performing familiar tasks, language problems, and changes in mood or behavior can all be early signs. Awareness of these symptoms is key, both for potentially mitigating the progression of the disease and for preparing to provide appropriate care.

Symptoms of early-onset Alzheimer’s disease can include the following:

Forgetting newly learned things such as important information or dates
Repeatedly asking for the same information
Trouble with problem-solving, such as tracking bills or following a favorite recipe
Losing track of date or time
Forgetting where you are and how you got there
Problems with depth perception or other vision problems
Difficulty having conversations or finding the right words
Misplacing things and needing help to retrace steps to find them
Increasing poor judgment
Withdrawal from work and social situations
Changes in mood and personality

Diagnosing & Treating Early-Onset Dementia

Symptoms such as memory loss, confusion, difficulty with familiar tasks, and changes in mood or behavior should prompt a comprehensive evaluation by a healthcare professional. Timely diagnosis allows individuals and their families to access resources, plan for the future, and implement strategies to maximize quality of life.

There is no cure for early-onset Alzheimer’s disease. However, treatment with medication can help maintain mental function, control behavior, and slow the progression of the disease. Other ways to prevent the progression of early-onset dementia can include:

Physical activity
Cardiovascular treatment
Diabetes treatments
Antioxidants
Cognitive training

Caring for Individuals With Dementia

For family members and caregivers, understanding how to support loved ones with dementia is essential. Creating safe, structured environments, engaging in clear communication, and nurturing positive emotional interactions are all supportive strategies.

Professional support in memory care can make a significant difference in the lives of those with dementia and their caregivers. Senior communities who provide these services lean on healthcare providers, medication management, trained and qualified staff, and support for daily living activities.

Support & Care for Dementia

Dementia can occur at various ages, from early adulthood to advanced age. While it’s more commonly associated with older adults, young-onset dementia presents its own set of challenges.

Understanding the age spectrum of dementia and its associated risk factors is essential for promoting early detection and intervention. If you have a loved one with dementia, contact Sommerset Neighborhood to learn more about our community and how we can support them with the right levels of care.
