Often mistaken for stress or exhaustion, early-onset Alzheimer’s disrupts the lives of at least 28,000 Canadians, accounting for between 2% and 8% of all neurocognitive disorder cases in the country.
We’ll help you recognize the signs of early-onset Alzheimer’s, understand its progression, and learn to live better with this form of the disease.
Early-onset Alzheimer’s, also known as young-onset Alzheimer’s, is a form of Alzheimer’s disease that occurs in adults under the age of 65. This means it generally affects people with busy professional lives and many family responsibilities, both of which are severely impacted by the disease.
Fortunately, knowledge and prompt diagnosis can pave the way to the right resources and a better quality of life.
Although it is possible for people as young as 18 to develop early-onset Alzheimer’s, it usually develops between the ages of 50 and 64. Onset before 40 is very rare. These cases are often linked to specific hereditary genetic mutations.
The signs of early-onset Alzheimer’s are similar to those of regular (late-onset) Alzheimer’s, but are often mistakenly attributed to stress, fatigue, or overwork, delaying diagnosis and treatment.
This form of Alzheimer’s is often detected later because its symptoms can be explained by other causes in younger people. As such, it’s important to know the signs to ensure that the disease can be diagnosed and managed as soon as possible.
Early-onset Alzheimer’s generally progresses through three distinct stages, each with its own challenges.
Early-onset Alzheimer’s often progresses more quickly than late-onset Alzheimer’s, in part because people are diagnosed later.
Genetics play a more important role in early-onset Alzheimer’s than in its other form. Certain inherited genetic mutations can considerably increase the risk of developing the disease before the age of 65.
Other factors can also contribute to the development of early-onset Alzheimer’s disease:
Smoking, a sedentary lifestyle, an unbalanced diet, a chronic lack of sleep, and social isolation can also increase the risk of developing early-onset Alzheimer’s.
Getting a diagnosis quickly is the key to ensuring the best possible treatment for early-onset Alzheimer’s. A doctor will help rule out other possible causes for the symptoms, such as depression, vitamin deficiencies, or thyroid problems.
Usually, confirming a diagnosis requires the following tests:
Early diagnosis makes it easier to plan for the future, while the person with Alzheimer’s is still able to participate in important decisions (financial arrangements, advance medical directives, family support plans, etc.). This gives them some control over their own life.
Although there is no cure for early-onset Alzheimer’s, there are several ways to slow progression and improve quality of life.
Certain medications can temporarily stabilize or slow cognitive decline in Alzheimer’s patients. These treatments can’t reverse existing damage in the brain, but they can offer much-needed respite and help patients maintain function for longer.
Your pharmacist can recommend medications, explain how they work, and help you manage possible side effects.
Complementary therapies play just as important a role as drugs in the management of early-onset Alzheimer’s. Here are a few examples:
When used in combination, these therapies help maintain abilities for as long as possible and improve the overall well-being of the person with Alzheimer’s.
No one should face Alzheimer’s on their own. A strong support network is essential. Here are some of the resources available to support and equip people with Alzheimer’s and their families.
