Intellectual disability and dementia are two distinct conditions, each with its unique set of characteristics and challenges. However, recent research has shed light on the interesting connection between these two conditions.
Intellectual disability, often referred to as developmental delay or cognitive impairment, is a condition characterized by limitations in intellectual functioning and adaptive behaviors. These limitations manifest before the age of 18 and can affect an individual’s ability to communicate, learn, and function independently.
In contrast, dementia is a syndrome with symptoms that impact memory, thinking, judgment, communication, and personality changes. The symptoms of dementia typically develop in older adults, although early-onset forms can affect younger individuals.
According to the Alzheimer’s Society of Canada, “one in 20 Canadians over age 65 has Alzheimer’s disease, the most common form of dementia. After 65, the risk of developing Alzheimer’s disease doubles approximately every five years, with one in four Canadians over 85 having Alzheimer’s disease.”
Among individuals with Down’s Syndrome, however, the risk is a lot higher. At the age of 50, individuals with Down’s Syndrome have a 30% chance of developing Alzheimer’s Disease; and, at the age of 60, they have a 1 in 2 risk for developing Alzheimer’s disease compared to the general population.
One of the main reasons for this increased risk is the extra chromosome associated with this genetic anomaly. Individuals with Down Syndrome have an extra chromosome, chromosome 21, which contains the genes that produce the proteins that cause the amyloid plaques seen among individuals with Alzheimer’s Disease.
In a recent interview I have given with Evan Kelly, Communications Manager on his Encouraging Abilities podcast, I talked about the risk of dementia among individuals with intellectual disabilities including the critical role caregivers play in preventing and managing dementia in this population.
Challenges in Diagnosis and Management
Diagnosing dementia in individuals with intellectual disabilities can be challenging due to communication difficulties and pre-existing cognitive impairments. Symptoms may be attributed to the individual’s baseline intellectual functioning, leading to delayed diagnosis and intervention. Moreover, healthcare providers may not always receive adequate training to recognize dementia in this population.
Like the general population, individuals with intellectual disabilities are living longer due to advancements in healthcare. With increasing age, the risk of developing dementia also rises, making this connection more significant as the population ages.
Managing dementia in individuals with intellectual disabilities requires a tailored approach. Whether you are a family or professional caregiver, we cannot emphasize enough that you play a crucial role in making observations, noting changes in behaviour and abilities, and communicating these changes to doctors and specialists. Here are a few strategies that could be helpful:
Early Detection: Regular cognitive assessments and screenings can help detect dementia in its early stages, enabling prompt intervention and support.
Supportive Environment: Creating a supportive living environment with familiar routines and minimal disruptions can help individuals with intellectual disabilities manage their dementia symptoms better.
Caregiver Education: Caregivers and support staff should receive training in dementia care tailored to the needs of individuals with intellectual disabilities. This includes communication techniques, behavior management, and strategies to address specific challenges.
Multidisciplinary care: A team approach involving physicians, psychologists, speech therapists, and occupational therapists can provide holistic care for individuals with both conditions.
The connection between intellectual disability and dementia highlights the importance of addressing the unique needs of this vulnerable population. As research continues to uncover the intricacies of this relationship, it is essential to advocate for improved awareness, education, and support for those at the intersection of these two conditions.
At Dementia Solutions, we’ve made it our mission to demystify dementia behaviour and continue to explore person-centred, creative, non-pharmacological solutions to manage dementia-related behaviours. We believe that awareness creation and skill-building through education is the most effective and powerful tool we have to promote and maintain the well-being of both the person with dementia and their caregiver.
If you need support in your caregiving experience or would like to learn more about our educational opportunities, please reach out to us at [email protected] and we would be more than happy to support you.
