Below you will find a series of commonly asked questions on memory disorders, diagnosis and treatment of memory disorders, living with Alzheimer's and information on memory and aging research. Click on the topic below for the full list of questions and answers.
What are memory disorders?
Memory disorders are brain-based conditions that affect retention and recollection of memories. Everyone experiences some lapse of memory periodically, and some decline in memory is normal as we age. However, with memory disorders, people have more significant memory loss that may interfere with their work, social activities, personality, behavior, and ability to perform daily tasks. Impairments in memory may be due to many conditions, Alzheimer's disease, vascular dementia caused by small strokes in the brain, diabetes or high blood pressure, normal pressure hydrocephalus (NPH), or even depression.
What is Alzheimer’s disease?
Alzheimer's disease (AD) is a specific type of dementia and the most common form. It is a progressive, degenerative disease that causes slow decline of nerve cells in the brain. Individuals with AD experience progressive and irreversible loss in thinking abilities, including language and memory. Changes are also witnessed in mood, personality, sleep-wake cycles, and behavior. In AD, nerve cells involved in learning and short-term memory are affected early which is the reason memory loss is one of the first symptoms of Alzheimer's disease.
What is dementia?
Many different conditions and diseases cause dementia. The term "dementia" is used loosely to describe severe memory loss and impairment in other thinking (or "cognitive") abilities that interfere with the individual's daily life and social interactions.
What is the difference between Alzheimer's disease and dementia?
Dementia refers to a category of disorders that involve memory loss while Alzheimer's disease is a specific disease. Alzheimer's disease causes dementia, however, several other diseases or conditions, such as stroke, Parkinson's disease, head injury, and vitamin deficiency can also cause dementia.
What are the stages of Alzheimer’s disease?
Alzheimer's disease has three stages: early (mild), middle (moderate), and late (severe). A person in the early stage of Alzheimer’s may:
- Find it hard to Remember things.
- Be repetitive.
- Get lost in familiar places.
- Lose things or put them in odd places.
- Have trouble handling money and paying bills.
- Take longer than normal to finish daily tasks.
Importantly, the first changes present within the brain may begin 20 or more years before diagnosis.
Those in the middle stage of Alzheimer’s exhibit:
- Increased memory loss and confusion.
- Difficulty recognizing family and friends.
- Difficulty learning new things and coping with new situations.
- Trouble completing tasks with multiple steps.
- Impulsive behavior.
- Forgetting the names of common items.
- Delusions, or paranoia.
The mild to moderate stage may last between 2 and 10 years.
In the late stage, people:
- Lose the ability to communicate.
- May sleep more.
- Lose weight.
- Have trouble swallowing.
- May be incontinent.
Severe Alzheimer’s may last between 1 and 5 years.
What is vascular dementia?
While Alzheimer’s disease is the most common type of dementia, the second most common type of dementia is vascular dementia. Vascular dementia is associated with problems in the circulation of blood to the brain (cerebrovascular disease). Risk factors for this type of dementia include:
- High blood pressure.
- Diabetes mellitus.
- High cholesterol.
- History of transient ischemic attacks (TIA).
- Heart rhythm abnormalities.
- Evidence of disease in arteries elsewhere in the body.
What is mild cognitive impairment?
An individual with mild cognitive impairment, or MCI, is able to take care of themselves and go about their normal daily activities, but they have subtle problems with memory and thinking. Some signs of MCI are losing things often, forgetting appointments, and having trouble finding the right words to say. MCI can be an early sign of Alzheimer’s disease—but not everyone with MCI will develop Alzheimer’s.
How can one recognize Alzheimer's disease from normal memory loss or ordinary forgetfulness?
Everyone experiences memory lapses and forgetfulness from time to time and some decline in memory ability is a normal part of aging. For example, as an individual approaches middle age, his or her ability to recall newly learned information, such as recalling people’s names or specific words, may begin to slip. These memory problems do not get worse over short periods of time and do not interfere much with the ability to do daily activities. People may compensate for these normal memory changes by repeatedly going over things to be remembered, linking them in their mind with something already well known, or keeping lists of things to do. In contrast, the memory loss in Alzheimer's disease is much greater than expected for age. The memory lapses are more frequent and severe and interfere with the ability to manage daily activities.
Are there warning signs for Alzheimer's disease?
What is typically the first sign?
- Memory Loss That Affects Day-to-Day Function. It is normal to occasionally forget appointments or phone numbers. However, a person with Alzheimer's disease may forget things more often and not remember them later. The disease prevents the person from making new memories. Memories of things from long ago often remain after the ability to learn new information is lost.
- Difficulty Performing Familiar Task. Busy people can be so distracted from time to time that they may forget what they are doing. For example, one may forget to serve the vegetables during dinner, but will remember to serve them at the end of the meal. A person with Alzheimer's disease may be unable to prepare any part of a meal or forget they ate it.
- Problems With Language. Everyone has trouble finding the right words sometimes, but a person with Alzheimer's disease may forget simple words or substitute the wrong words, making his or her sentences difficult to understand. The conversation of a person with Alzheimer's disease may wander excessively.
- Disorientation of Time and Place. It is normal to forget the day of the week or your destination-for a moment. But a person with Alzheimer's disease can have persistent problems remembering the date, day of the week, or time. They may have more trouble finding their way while driving and may occasionally get lost.
- Poor or Decreased Judgment. People may sometimes put off going to the doctor if they have an infection but eventually will seek medical attention. A person with Alzheimer's disease may not recognize the need for a doctor at all. Another example of poor judgment is that a person with Alzheimer's disease may dress inappropriately, wearing heavy clothing on a hot day, or two shirts. People with Alzheimer's disease may become distracted and unsafe while doing routine activities such as cooking or driving.
- Problems with Abstract Thinking. Trouble balancing a checkbook may be an early warning of a more serious problem.
- Misplacing Things. We all misplace things from time to time. Frequently misplacing items may indicate an underlying memory disorder. Later in the illness, a person with Alzheimer's disease may put things in inappropriate places: an iron in the freezer or a watch in the sugar bowl and forget that they put them there. They may also accuse others of stealing when they are unable to find things they need.
- Changes in Mood or Behavior. Everyone becomes sad or moody from time to time. Depression may be the first sign of an underlying memory disorder in an older person. Someone with Alzheimer's disease can exhibit a wide range of mood or behavioral changes. For example, they may display rapid mood swings - from calm to tears to anger - for no apparent reason, or become abnormally irritable, depressed, or agitated. They may have changes in their eating, sleeping, and hygiene and may engage in repetitive purposeless behaviors such as rummaging through closets and drawers.
- Changes in Personality. People's personalities can change somewhat with age. But a person with Alzheimer's disease can change dramatically, becoming, suspicious or withdrawn. Changes may also include apathy or indifference, fearfulness or anxiety, or acting inappropriately.
- Loss of Initiative. It is normal to lose interest and motivation in housework, business activities, or social obligations, but most people regain their initiative. A person with Alzheimer's disease may become very passive and require cues and prompting to become involved in daily activities. The symptoms of apathy are not distressing to the patient but can be very disturbing for the caregiver and family.
How is Alzheimer's disease diagnosed?
Testing brain tissue for plaques and tangles is the only definitive way to diagnose Alzheimer’s disease. This is done during a brain autopsy after someone dies. While a person is still living, doctors are only able to make a diagnosis of “possible” or “probable” Alzheimer’s disease and this requires a full physical and neurological examination to rule out other causes of dementia. Screenings include blood tests to measure thyroid function and vitamin B12 levels, an MRI or CT scan of the brain to exclude other causes of dementia such as strokes, tumors, or hydrocephalus (excessive fluid build-up in the brain), and cognitive testing for memory, language, and other cognitive difficulties.
What treatments are there for Alzheimer's disease?
There is no medical treatment currently available to cure or stop the progression of Alzheimer's disease. However, the Food & Drug Administration (FDA) has approved four drugs that may temporarily relieve some symptoms of the disease or slow its progression. These are tacrine (Cognex®), donepezil (Aricept®), rivastigmine (Exelon®), and galantamine (Reminyl®). Many other new promising drugs are now being developed - some of which may be available within the next few years. Medication and non-drug therapies are also available to reduce some of the changes in behavior associated with Alzheimer's disease, such as depression, sleeplessness, and agitation.
Are there side-effects from the medication prescribed for Alzheimer's disease?
Generally, donepezil (Aricept®), rivastigmine (Exelon®), and galantamine (Reminyl®) are well tolerated. Symptoms such as nausea, vomiting, loss of appetite, and loose stools might occur but are usually transient. It is recommended to take Reminyl® and Exelon®with a full meal. Because of side effects associated with tacrine, including possible liver damage, it is very rarely prescribed. There is no evidence or reason to believe that combining the drugs would be any more beneficial than taking either one alone, and it is likely that combining the drugs would result in greater side effects.
What vitamins and herbal supplements are protective against Alzheimer's disease?
Research into the production of free radicals in the brain in Alzheimer's disease have suggested that antioxidants, such as vitamin E, vitamin C, and Ginko Bilbao may be useful in treating or slowing the progression of the disease. However, more research needs to be done in this area before the effectiveness or lack thereof of these supplements can be verified.
- Vitamin E. An article published in the New England Journal of Medicine demonstrated that Vitamin E can slow the disease course in patients with moderate-severe Alzheimer's disease. An article published recently in the Journal of the American Medical Association suggested that high levels of dietary vitamin E might be protective against the development of Alzheimer's disease. This study found a benefit when patients ate vitamin E in the form of natural foods, but found no benefit when it was taken as a vitamin supplement. More studies need to be done to understand the protective role that this vitamin may play. Vitamin E supplements are frequently prescribed and have become a part of a standard treatment regimen for most people with Alzheimer's disease.
- Vitamin C. Vitamin C, like Vitamin E, plays an antioxidant role by neutralizing free radicals and preventing cell death. More studies need to be done to investigate whether Vitamin C can limit Alzheimer's disease progression.
- Ibuprofen and other Nonsteroidal anti-inflammatories (NSAIDS). There is evidence that NSAIDS may play a preventative role in the development of AD but have no benefit on disease course in people diagnosed with AD, more research is needed. The role of NSAIDS in Alzheimer's disease is an active area in AD research and its benefits, if any, are unclear.
- Gingko biloba. Gingko biloba has antioxidant and vasodilating properties. Several clinical trials have suggested that gingko is effective in the treatment of Alzheimer's disease (AD). There have been some contraindications of gingko when using anticoagulants, so you should speak with your physician before starting on this, or any supplement. A recent study in Journal of the American Medical Association showed no benefit for gingko in patients with AD and we do not currently recommend it.
Are people with Alzheimer's disease aware of their symptoms?
Patients in the early stages of Alzheimer's disease may have awareness of their memory and other deficits. However, awareness of memory and other problems generally decreases as the disease progresses.
Can people with Alzheimer's disease live alone?
Approximately 25 percent of Americans with Alzheimer's disease live alone. However, as the condition progresses, patients may need more help and it is especially important for family and friends to provide supervision for tasks that the person with AD can no longer do for themselves. Family members, friends, and community services can help. Information is available on home care services, meals, transportation, and day care from the Alzheimer's Association or a primary care physician. Arrangements can be made for direct deposit of checks such as retirement pensions and/or Social Security benefits. Home-delivered meals are available. At some point people with AD will need to live in a supervised setting either with family, an assisted living facility, or a nursing home.
If an individual has been diagnosed with Alzheimer's disease, should they continue to drive?
Whether or not a person with Alzheimer's disease can continue to drive is dependent on the progression of the disease and their remaining functional abilities. Individuals who still drive should be encouraged to limit their driving to short distances in areas that are familiar to them. Caregivers should try to gauge whether they feel that the person is driving safely. After evaluation in the Memory Clinic, our staff can advise patients and their families regarding driving safety, and refer patients for driving safety evaluations if indicated.
Should a person tell friends and family that they have been diagnosed with Alzheimer's disease?
People with Alzheimer's disease will need support and assistance from others as they experience changes brought on by the disease. While telling friends and family may cause some emotional stress, it is important to tell people early on so that an effective and caring support network of family and friends can be established.
Do all people with Alzheimer's disease wander? Do all get irritable?
Behavior problems are common in AD, especially as the disease progresses. Depression and irritability may occur early. Suspiciousness is common. Apathy is the most common behavioral symptom. Restlessness, wandering, agitation, impulsiveness, delusions, and hallucinations may occur later. These behavioral symptoms can be very distressing to caregivers and family members. It is important to have the support of family and friends. Support groups may help. Medications may help. Your family doctor may refer you to a geriatric psychiatrist who specializes in managing behavioral problems in dementia.

Is Alzheimer's disease hereditary? Does having a parent who has the disease increase my chances of developing it? If so, are there any tests that clarify my risk?
The average worldwide lifetime risk of developing any type of Alzheimer’s disease is about 5 percent by age 65, 10 to 15 percent by age 75, and 20 to 40 percent by age 85. Individuals who have a parent with Alzheimer’s disease have about twice the average risk of getting the disease, that is, among 65-year-olds with an affected parent, about 10 percent will develop Alzheimer’s disease.
Having a brother or sister with Alzheimer’s disease also doubles the risk. The likelihood of developing the disease continues to increase as the number of affected relatives increases, and having more than one affected sibling appears to cause the greatest increase in risk. This increased risk occurs because children and parents may share certain genes, the basic units of heredity that provide a blueprint for many biological and behavioral characteristics. The influence of a gene may be large or small. Tests are available that can determine whether a person carries Alzheimer’s disease genes. It is important to understand, however, that even people with Alzheimer’s disease genes may not develop the disease.
In addition, an Alzheimer's disease diagnosis approaches 90 percent accuracy without genetic testing. Therefore, genetic testing is usually not essential, but is recommended in those patients with early onset of symptoms (early onset AD is associated with greater likelihood of a genetic link) and a positive family history. Most experts regard genetic testing as an acceptable part of clinical trials as long as participants give informed consent and understand the procedure’s purpose and limitations thoroughly. Most experts recommend that the complex analysis involved in characterizing such one-of-a-kind gene mutations be carried out at a major academic center and that individuals receive genetic counseling as part of the testing process. Genetic counselors help people explore emotional and legal implications as well as scientific and technical issues before testing proceeds; after testing is completed, they explain and interpret results and help people accept the outcome.
Why is early diagnoses of Alzheimers Disease important?
An early diagnosis of Alzheimer’s Disease helps families to plan for the future and make legal and financial arrangement while allowing the person with Alzheimer’s to take part in the decision-making process. Early diagnosis can also allow for the person to begin medications that can help slow the disease progress. Importantly, early diagnosis can allow the person to take part in clinical research trials that could change the future of the disease.
What is clinical research and why is it an important part of Alzheimer's disease research?
Clinical research includes studies (observing and gathering data from large groups of people) and trials (testing a medicine, therapy, or intervention in a group of people). Clinical trials are important as they allow researchers and doctors to determine if a medication or treatment is successful in slowing or preventing the disease progression. Our clinic has many opportunities for clinical research, click here to see our current trials.
What is beta-amyloid?
Beta-amyloid is a sticky protein that gradually builds up, forming plaques within the brain of those with Alzheimer’s disease. The plaques accumulate between nerve cells in the brain, blocking their communication.
What is tau?
Tau is a protein that, under normal conditions, allows vital cell transport to occur within the brain. In Alzheimer’s Disease, tau collapses into twisted strands which stops the cell from obtaining essential supplies and nutrients. Cells with these tau tangles eventually die.
What are plaques and tangles?
Plaques are abnormal clusters of beta-amyloid protein. Tangles are twisted strands of tau protein. Plaques and tangles accumulate in the brain of those with Alzheimer’s disease. Specific types of recently developed PET scans are able to detect this accumulation. Previously, all plaque and tangle quantification was done through autopsy.
What are PET scans?
Positron emission tomography (PET) uses small amounts of radioactive material, called radiotracers, and a specialized camera and computer to “see” your organs and tissues. In Alzheimer’s research, PET scans are used to detect beta-amyloid and tau accumulation, as well as healthy and diseased tissue through use of a variety of radiotracers. The PET scan procedure begins with the technician placing an IV in your hand or arm and injecting the radiotracer. A period of time will pass as your brain absorbs the radiotracer. After the radiotracer is absorbed, you will enter the PET scanner, a large round machine similar to an MRI machine. The PET scanner will use a specialized camera to detect the radiotracer within your brain. You will not feel anything as this process occurs.
What is an MRI?
An MRI is a test that uses a large magnetic field and radio wave energy to recreate images of structures within the body. In Alzheimer’s research, MRIs are often used to image the brain as a whole, as well as specific structures within the brain. MRI images can tell doctors if brain tissue volume is shrinking, whether large or small strokes have occurred, and whether specific brain areas are displaying abnormalities.
What is a lumbar puncture?
A lumbar puncture is a procedure in which a doctor places a small needle between the vertebra in the back and into the spinal canal. Cerebral spinal fluid (CSF), the liquid that surrounds the brain and spinal cord, is collected and analyzed for a variety of components. In Alzheimer’s research, the CSF is often analyzed for beta-amyloid and tau proteins, as well as levels of investigational medications (if the person is enrolled in a research trial).
Research trials involve “cognitive testing.” What is this?
Cognitive testing refers a variety of assessments designed to measure a persons memory and thinking abilities. In Alzheimer’s research, cognitive testing often entails surveys, questionnaires, interviews, and sessions with a trained cognitive rater or doctor.
Can I stop participating in a study after I sign up?
Of course. Before beginning any research trial you will be told of each and every step that the study will entail. All of your questions will be answered and should you feel comfortable continuing in the trial, you will sign a consent form. At any point, you are free to withdraw your consent and stop participating in the study.
Who will know I am in a research trial?
All the procedures done for a research trial are done independent of your insurance or primary care doctor. The only people that will know you are in a trial are the people at the clinic who are involved in the trial and the people that you decide to tell. We work hard to make sure your information is kept confidential.
Can I sign up for any research trial I want?
No, there are strict criteria that must be met to enroll in a research trial. Our clinic doctors will determine which studies they believe you may be a good candidate for and, after signing consent, you will enter into a screening period. If you meet all criteria during the screening period, you will be enrolled in the trial. If you do not meet the necessary criteria for a study, there may be others that you will qualify for. You can only be enrolled in one clinical trial at a time.
What is a placebo?
A placebo is an inactive substance designed to look like a medication. Drug trials are often ‘placebo-controlled’ meaning that some of the participants in the trial are not receiving the drug being tested, but are instead receiving a substance made only to look like the medication. Often a placebo is called a sugar pill because it does not contain any active medicines. Placebo groups serve as control groups in research. Results are compared between the placebo group and the active medication group to determine if the medicine is having an effect.
