When Alzheimer's begins in middle age, misdiagnosis may be more likely. This rare form of Alzheimer's affects work, finances and family.By Mayo Clinic Staff
Early-onset Alzheimer's is an uncommon form of dementia that strikes people younger than age 65. Glenn E. Smith, Ph.D., a neuropsychologist at Mayo Clinic, Rochester, Minn., answers questions about this condition.
Of all the people who have Alzheimer's disease, about 5 percent develop symptoms before age 65. So if 4 million Americans have Alzheimer's, at least 200,000 people have the early-onset form of the disease.
Early-onset Alzheimer's has been known to develop between ages 30 and 40, but that's very uncommon. It's more common to see someone in his or her 50s who has the disease.
Some people with early-onset Alzheimer's have the common form of the disease, and experts don't know why these people get the disease at a younger age than others do.
For most, however, early-onset Alzheimer's runs in the family. They're likely to have a parent or grandparent who also developed Alzheimer's at a younger age.
Early-onset Alzheimer's that runs in families is linked to three genes that differ from the APOE gene that can increase your risk of Alzheimer's in general. The genetic path of inheritance is much stronger in early-onset Alzheimer's. If you have a genetic mutation in one of those three genes — the APP, PSEN 1 or PSEN 2 — you may develop Alzheimer's before age 65.
That's a personal decision that only you can make. Anyone who's considering it should pursue genetic counseling — to examine the pros and cons beforehand.
For example, it may be helpful to consider how a positive test may affect your eligibility for long-term care, disability and life insurance.
On the other hand, if you know you carry a form of the early-onset genes, you may be able to take steps to make it easier for you and your loved ones to cope with the effects of the disease.
There's a perception that it does, but it's not backed up by hard data. It depends on what endpoint you're using in your measurement. If the endpoint is admission to a nursing home, that may occur earlier for the early-onset group — but only because their spouses or partners may have more things to deal with, such as children and jobs, than older spouses do.
For example, people who have early-onset Alzheimer's often still have children at home. They or their spouses or partners may have elderly parents that need care, too. Often, people may find themselves overwhelmed with caring for elderly parents, the loved one with early-onset Alzheimer's and their children all at the same time.
Fortunately, resources are available to support people with Alzheimer's to care for themselves and function on their own as long as possible. Many resources are also available for caregivers. Support that can be essential when dealing with early-onset Alzheimer's.
Accurate diagnosis is critical so that you can explain your condition to your employer and perhaps arrange a lighter workload or more convenient schedule. For family reasons it is even more crucial.
The diagnosis is fundamental in helping the family respond with appropriate understanding and compassion. In addition, a complete evaluation will rule out reversible forms of dementia that might improve with treatment.
Alzheimer's disease has a tremendous impact at any age. But we don't expect to see dementia at a young age, so problems emerging at work or home may be misunderstood. People with early-onset Alzheimer's may lose relationships or jobs instead of being identified as medically ill or disabled.
Before your condition significantly affects your ability to do your job, talk to your employer. What you can do:
- Find out if you can switch to a position that better suits your emerging limitations.
- Familiarize yourself and your spouse, partner or caregiver with your benefits, and find out whether an employee assistance program is available.
- Explore what benefits may be offered to you under the Americans with Disabilities Act.
- If you feel overwhelmed, consider reducing your hours or taking time off.
The loss of intimacy is something poignant with early-onset Alzheimer's. Many people who develop late-onset Alzheimer's have already been widowed. But couples in their 40s or 50s are often in the middle of their lives together.
Spouses or partners face the possibility of spending many years without an active partner. Losing the romantic component and changing to a caregiver status complicates the relationship. Try to:
- Communicate about changes you're experiencing and ways in which your needs also may have changed. Don't be afraid to ask for help.
- Find new activities that you can enjoy together.
- Keep a folder of resources you may need as the disease progresses.
- Find a counselor who works with couples facing issues you feel challenged by, such as sexuality and changing roles in the relationship.
A diagnosis of early-onset Alzheimer's also can be difficult for your children, who may not understand what you may go through. Children may blame themselves, become angry or react in any number of ways. Try to:
- Find activities you can enjoy together.
- Stay engaged and talk with your children honestly about what you're experiencing.
- Find a support group for children, and invite your kids to some of your counseling sessions. Make your child's school counselor and social worker aware of your condition.
- Keep a written, video or audio record of your thoughts, feelings and experiences for your children. They'll appreciate your sharing your wisdom and memories.
People with early-onset Alzheimer's often have to quit work, and this loss of income is a serious concern. Finances get even tighter if spouses or partners also quit their jobs to become full-time caregivers.
Some medical benefits and many social-support programs won't provide assistance unless the person with Alzheimer's is older than age 65. Younger people may need special waivers to get into such programs. What you can do:
- Talk with a financial planner and an attorney to help you plan for your future financial needs.
- Ask your employer whether early retirement is an option.
- Explore what benefits may be available to you through Social Security, Medicare or Medicaid.
- Organize your financial documents and make sure your spouse or partner understands and can manage your family's finances.
Key elements of Alzheimer's care are education and support. This is especially true given the unique social challenges of early-onset Alzheimer's. Getting connected to services such as support groups can help you identify resources, gain a deeper understanding of the disability and learn ways to adapt.
Remember, you're not alone. Many resources are available to assist you, your family and caregivers to cope with this disease. Options for support may vary depending on where you live.
Be sure in the early stages of the disease that you and your spouse or partner do research and establish a plan for managing the progression of your condition. Knowing you have a plan and have identified support and resources will help everyone in the future.
