Improving Your Memory (16 page)
Scientists believe that whatever triggers Alzheimer’s disease begins to damage the brain years before symptoms appear.
When symptoms emerge, nerve cells that process, store, and retrieve information have already begun to degenerate and die. Scientists regard two abnormal microscopic structures called “plaques” and “tangles” as the hallmarks of Alzheimer’s disease. Amyloid plaques (AM-uh-loyd plaks) are clumps of protein fragments that accumulate outside of the brain’s nerve cells. Tangles are twisted strands of another protein that form inside brain cells. Scientists have not yet determined the exact role that plaques and tangles may play.
Diagnosing Alzheimer’s Disease
Although Alzheimer’s symptoms can vary widely, the first problem that many people notice is forgetfulness severe enough to affect performance at home, at work, or in favorite activities. Sometimes the decline in memory may be more obvious to a family member or close friend than to the affected individual. Other common symptoms include confusion, getting lost in familiar places, and difficulty with language. The Alzheimer’s Association encourages everyone who notices these symptoms in themselves or someone close to them to consult a physician.
A skilled physician can diagnose Alzheimer’s disease with 90 percent accuracy. Because there is no single test for Alzheimer’s, diagnosis usually involves a thorough medical history and physical examination as well as tests to assess memory and the overall function of the mind and nervous system. The physician may ask a family member or close friend about any noticeable change in the individual’s memory or thinking skills.
One important goal of the diagnostic workup is to determine whether symptoms may be due to a treatable condition. Depression, medication side effects, certain thyroid conditions, excess use of alcohol, and nutritional imbalances are all
potentially treatable disorders that may sometimes impair memory or other mental functions. Even if the diagnosis is Alzheimer’s, timely identification enables individuals to take an active role in treatment decisions and planning for the future.
Alzheimer’s is the leading cause of dementia, a group of conditions that all gradually destroy brain cells and lead to progressive decline in mental function. Most diagnostic uncertainty arises from occasional difficulty distinguishing Alzheimer’s disease from one of these related disorders.
Other Causes of Dementia
Vascular dementia
results from damage caused by multiple strokes within the brain. Symptoms can be similar and can even coincide with Alzheimer’s disease and may include disorientation, confusion, and behavioral changes.
Normal pressure hydrocephalus (NPH)
is a rare disease caused by an obstruction in the flow of spinal fluid leading to a buildup of fluid in the brain. Symptoms include difficulty in walking, memory loss, and incontinence. NPH may be related to a history of meningitis, encephalitis, or brain injury and is occasionally correctable with surgery.
Parkinson’s disease
affects the control of muscle activity, resulting in tremors, stiffness, and speech difficulties. In late stages, dementia can occur. Parkinson’s drugs can improve steadiness and control but have no effect on mental deterioration.
Dementia with Lewy bodies
is a disorder that, although progressive, is often initially characterized by wide variations in attention and alertness. Affected individuals often experience visual hallucinations as well as muscle rigidity and tremors similar to those associated with Parkinson’s disease.
Huntington’s disease
is a fatal, progressive, hereditary disorder characterized by irregular movements of the limbs and facial muscles, a decline in thinking ability, and personality changes.
Frontotemporal dementia, also known as Pick’s disease,
is a rare brain disease that closely resembles Alzheimer’s, with personality changes and disorientation that may precede memory loss.
Creutzfeldt-Jakob disease (CJD)
is a rare ultimately fatal disorder of infectious or genetic origin that typically causes memory failure and behavioral changes. A recently identified form called “variant Creutzfeldt-Jakob disease (vCJD)” is the human disorder thought to be caused by eating meat from cattle affected by “mad cow disease” (bovine spongiform encephalopathy). Variant CJD tends to appear in much younger individuals than those affected by sporadic or inherited Creutzfeldt-Jakob.
Treating Alzheimer’s Disease
Currently, there is no cure for Alzheimer’s and no way to stop the underlying death of brain cells. But drugs and nondrug treatments may help with both cognitive and behavioral symptoms. Two types of drugs are currently approved by the U.S. Food and Drug Administration (FDA) to treat cognitive symptoms of Alzheimer’s disease.
One important part of treatment is supportive care that helps individuals and their families come to terms with the diagnosis, obtain information and advice about treatment options, and maximize quality of life through the course of the illness.
As the pace of research accelerates, scientists funded by the Alzheimer’s Association, the pharmaceutical industry,
universities, and our federal government have gained detailed understanding of the basic disease process at work in the Alzheimer brain. Experts believe that several of these processes may offer promising targets for a new generation of treatments to prevent, slow, or even reverse damage to nerve cells.
About the Alzheimer’s Association

Understanding the Memory Process (

When you go to the library and see a lot of colorful books on the “new books” shelf, the component of memory you are using is
sensory input.
You read through the titles and think about whether they interest you. These conscious thoughts occur in the component of memory called
working memory.
Then you find a book by a favorite author, John Grisham. You take down the book, notice how long it is, read the back cover, think it sounds familiar, and decided that you have read this book before. This process is called
encoding.
The information about the book leaves your conscious thought and goes into the component of memory called
long-term memory,
where it may be available for
retrieval
at another time. When
you get home, you notice another of Grisham’s books on your nightstand. This favorite book serves as a
cue
to remind you of the book in the library. The connection between the library book and your book at home is called
association.
