Although the public most often associates dementia with Alzheimer’s disease, the medical profession now distinguishes various types of “other” dementias. This book is the first and only comprehensive guide dealing with frontotemporal degeneration (FTD), one of the largest groups of non-Alzheimer’s dementias. The contributors are either specialists in their fields or have exceptional hands-on experience with FTD sufferers.

Beginning with a focus on the medical facts, the first part defines and explores FTD as an illness distinct from Alzheimer’s disease. Also considered are clinical and medical care issues and practices, as well as such topics as finding a medical team and rehabilitation interventions. The next section on managing care examines the daily care routine including exercise, socialization, adapting the home environment, and behavioral issues. In the following section on caregiver resources, the contributors identify professional and government assistance programs along with private resources and legal options. The final section focuses on the caregiver, in particular the need for respite and the challenge of managing emotions.

This new, completely revised edition follows recent worldwide collaboration in research and provides the most current medical information available, a better understanding of the different classifications of FTD, and more clarity regarding the role of genetics. The wealth of information offered in these pages will help both healthcare professionals and caregivers of someone suffering from frontotemporal degeneration.

Editorial Reviews

Library Journal
Experts estimate that around two million people in the United States suffer from severe dementia, and another one to five million experience mild to moderate cases. While most people associate dementia with Alzheimer's disease, frontotemporal degeneration (FTD) accounts for around five percent of the cases. The coauthors, son and wife of an FTD sufferer, cared for their loved one until he died at 58. This third edition of their book ably gathers the significant medical developments of the last seven years into an excellent guide for caregivers. Sections written by experts and experienced caregivers cover the medical and genetic aspects of FTD, working with health professionals, medical therapy options, rehabilitation interventions, the stages of the disease, and practical aspects of daily care. VERDICT While there is some overlap among the individual chapters, this guide presents a wealth of medical information, written in terms the interested layperson can understand, as well as practical advice. One of the few books to discuss FTD specifically, this is an invaluable resource for patients, family, and friends, as well as health-care providers.—Marcia G. Welsh, Dartmouth Coll. Lib., Hanover, NH

The most common cause of dementia is Alzheimer's disease (AD), which has dominated our thinking about neurodegenerative disorders and even determined the definition of the term dementia itself. It is clear, however, that there are many other causes of dementia. Before discussing these it is first necessary to consider what is meant by dementia and the history behind it.

The term dementia refers to a clinical syndrome, a combination or pattern of clinical features. Thus, dementia is not a disease but rather a syndrome that can be associated with many different underlying diseases. In this sense it is similar to heartburn or headache, which is caused by many different things and could require many different treatments. Therefore, the statement that somebody has dementia is an inadequate diagnostic formulation: One must always try to determine the cause by appropriate investigations.

With the syndrome dementia, impairment of cognitive function is widespread. It can involve, in different combinations, memory for events; memory and understanding of facts, language, thinking, and reasoning; and perception of the world. Identifying patients with this combination of cognitive impairment was particularly important in the days before imaging (e.g., MRI and CT). It was important to distinguish patients with a localized deficit from those with more widespread problems. Cognitive function in the brain is modular, and particular areas of the cerebral cortex are specialized for particular functions; for example, our ability to remember day-to-day events is critically dependent on the hippocampus, which is found on the inside of the temporal lobes. (See figure 1.1.)

What the Different Parts of the Brain Do

Cerebrum: This is the term for the major part of the brain. The cerebrum is responsible for many aspects of thinking, including memory, problem solving, language function, personality, mood, and response to different sensory signals from the world around us. It also plays a role in movement and in feeling the senses. It is highly developed in humans but more rudimentary in animals.

Cerebellum: This part of the brain coordinates, smoothes out, and balances movement to enable us to stand, walk, and use our arms.

Frontal lobe: This part of the brain controls our ability to use words and speech (the left side) and determines how we react to situations. The frontal lobes are also important for problem solving, mood, judgment, inhibiting impulses, and for individual personality.

Parietal lobe: This part of the brain enables us to interpret sensory input such as pain, temperature differences, vibration, and touch. The left parietal lobe is involved with planning complex movements, and the right parietal lobe is important for our sense of direction.

Occipital lobe: This part of the brain interprets what we see.

Temporal lobes: The temporal lobes are crucial for formation of new memories (remembering). This part of the brain is nearly always involved in Alzheimer's disease and may be involved in frontotemporal dementia (FTD). The left temporal lobe is also important for understanding what we hear.

Brain stem: This connects the brain with the spinal cord. Without the brainstem, we would not be able to move or feel anything. This area is also important for automatic reflexes such as breathing.

Our language functions are critically dependent on areas of the left frontal and temporal cortex in right-handed people. Patients with a discrete abnormality, such as a loss of language or dysphasia, by implication would have a focal or localized damage to the cerebral cortex. If this were of sudden onset, it would likely be a stroke, but if it were of slow onset, then it would likely be a tumor and thus require invasive and potentially dangerous investigation and surgery. On the other hand, a patient with widespread deficits would likely have a disease more diffusely affecting the cerebral cortex, such as Alzheimer's disease, and further investigation could be avoided. Historically the terms senile and presenile dementia were used merely to refer to dementias coming on late or early in life. These were most likely to be Alzheimer's disease, but again this was not a specific diagnosis as such.

More recently the definition of dementia has been made more precise. The necessity for more than one cognitive domain to be involved remains critical to the definition; however, memory, and particularly our ability to remember day-to-day events (episodic memory), has to be affected for dementia to occur. Alzheimer's disease, in which episodic memory is the most salient deficit, is the most common dementia disorder. In addition to memory impairment, there has to be at least one other domain of cognitive impairment, such as language, thinking, or perception. Furthermore, the cognitive impairment has to be significant enough to interfere with social or employment functions. In other words, the patient must be quite severely impaired. More recent definitions of dementia give less prominence to memory as causes of dementia other than Alzheimer's disease are increasingly recognized.

The different degenerative diseases that can cause the dementia syndrome tend to affect different areas of the cerebral cortex. Since different areas of the cortex are specialized for different functions, the disease will tend to have characteristic patterns of deficit. This is most apparent early in the disease. As the disease progresses, the patterns become more similar as dysfunction becomes more severe and more widespread. Clearly, as we move toward earlier diagnosis, which is essential to successful management of these diseases in the future, we will attempt to diagnose them before a patient fulfills the criteria for dementia. For example, a patient with early Alzheimer's disease may present with mild memory deficit, but this alone is not sufficient to fulfill the criteria for dementia. Similarly, many patients with frontotemporal dementia may have preserved memory early in the disease but demonstrate quite profound behavioral and personality changes. For these reasons, many specialists now believe we should begin to move away from the term dementia and to speak in terms of specific patterns of cognitive impairment and the relationship to presumed underlying diseases. The term mild cognitive impairment (MCI) has been introduced to describe patients with cognitive problems that are not severe enough to justify the term dementia.


Frontotemporal degenerations (FTDs) compose the main topic of this book, and the clinical and pathological details are discussed in the following chapters. However, the key feature of this group of disorders is the involvement by a variety of disease processes of the frontal lobes and the front part of the temporal lobes of the brain. It is this characteristic distribution or topography of the degenerative process that determines the clinical features of early personality change and language and speech impairment. There are many different underlying diseases that can present as frontotemporal degeneration. Some of these are quite specific, such as Pick's disease. Pick's disease was identified even earlier than Alzheimer's disease. Arnold Pick in Prague described two patients with prominent behavioral and language impairment. Intriguingly, it was Dr. Aloysius "Alois" Alzheimer who again applied his expertise with the microscope to the examination of the brain and demonstrated some abnormal inclusions subsequently referred to as Pick bodies. These are now known to be deposits of tau protein. The tau protein that is deposited in Pick's disease is the same as that found in the neurofibrillary tangles of Alzheimer's disease, but is deposited in a different way. Senile plaques are not a feature of Pick's disease.

The term Pick's disease has been somewhat confusing, since it has been used both as a general clinical term, essentially the same as frontotemporal degeneration, as well as a very specific pathological disease. Increasingly it is used in the latter sense.

Corticobasal degeneration (CBD) is another disease of abnormal tau. Typically it affects the parietal lobe and causes major difficulty with motor skills but can affect the frontal and temporal lobes, causing FTD.

Some cases of FTD show deposits of a protein TDP-43 found in another degenerative disorder, motor neuron disease or Lou Gehrig's disease, also known as amyotrophic lateral sclerosis (ALS). FTD can run in families, and most of the gene abnormalities have now been identified.

It is the early behavioral and personality changes and/or changes in language and speech that define this group of patients. Their memory for day-to-day events may be strikingly preserved when compared with Alzheimer's disease, and they very rarely if ever get lost until late in the disease. Three prototypic clinical syndromes have been described in association with FTD: a frontal behavioral syndrome, progressive nonfluent aphasia, and semantic dementia. The frontal syndrome is characterized by behavioral abnormalities. Patients become socially disinhibited, with some becoming apathetic. There may be changes in eating and sexual behavior. The term frontotemporal degeneration is sometimes confined to this behavioral group. Progressive nonfluent aphasia refers to patients with speech-production difficulties. Early on, they have excellent comprehension and may write well despite speaking with difficulty. As the disease progresses, they can become mute. Semantic dementia refers to patients with impairment of semantic memory. This term refers to our knowledge of meaning. Verbal semantic memory is our memory for the meaning of words, and visual semantic memory is our memory for the meaning of objects that we see. Semantic memory contrasts with our memory for day-to-day events, referred to as episodic memory. Patients with semantic memory speak fluently, but their speech is empty of meaning and they have major difficulty understanding language. With this condition there is loss of tissue in the temporal lobes.


Dementia with Lewy bodies (DLB) has been increasingly identified as an important cause of dementia in the elderly. In some studies it is believed to be the cause of dementia in up to 20 percent of the patients over sixty-five years of age. Under the microscope, the brains of people with DLB show the senile plaques of Alzheimer's disease but far fewer neurofibrillary tangles. By contrast, they show the brain-cell changes that are normally associated with Parkinson's disease, that is, a protein deposit referred to as a Lewy body, named after its original discoverer.

Patients with DLB more closely resemble patients with Alzheimer's disease than those with FTD. There is a characteristic clinical triad that favors the diagnosis, namely fluctuation in the cognitive impairment, hallucinations, and Parkinsonian syndrome.

The fluctuations in cognitive impairment can be quite dramatic and last from minutes to days. In between times, the family will often feel that the patient is normal, at least early in the disease. The hallucinations are very frequent, and patients often retain insight. They are normally of people and animals. The people may often be familiar to them and distressingly may be deceased relatives or friends. The hallucinations are rarely threatening and rarely speak to the patients. They commonly accompany misidentifications of objects in their environments. For example, an abnormally hanging curtain may be seen as a figure that then takes the form of a more definite hallucination.

The Parkinsonian syndrome is very similar to that seen in patients with classical Parkinson's disease. There is a gradual slowing of movement and of rigidity, but the tremor or shakiness of classical Parkinson's disease is less often seen. A significant proportion of patients with Parkinson's disease, particularly the elderly, will develop cognitive impairment as the disease progresses. The features are similar to DLB, but when the dementia follows a diagnosis of Parkinson's disease it is referred to as Parkinson's disease dementia.


It is often claimed that there is an epidemic of Alzheimer's disease. The disease has always been with us, but since it is a disease of old age, the numbers of cases have increased with the aging of the population. The real increase, however, has been due to current diagnosis, whereas thirty years ago many patients would simply have been diagnosed as suffering from senile dementia.

Alzheimer's original case was a lady of only fifty-one years of age who presented with dementia. Alzheimer examined her brain after death using the newly available silver stains. He was thus able to demonstrate the two characteristic microscopic features of Alzheimer's: senile plaques and neurofibrillary tangles. Senile plaques are now known to reflect deposits of an abnormal protein, beta-amyloid, within the brain but not within the neurons or brain cells themselves; this is thought to be a key event in the causation of the disease. Neurofibrillary tangles are now known to be abnormal deposits of another protein within the cell itself. This protein is tau, the microtubule-associated protein. Microtubules are the building blocks of the internal skeleton of brain cells and are essential to maintain the integrity of the extensive and complex wiring within the brain. If tau loses its function, then microtubules become unstable, and one can see the collapse of the cytoskeleton as neurofibrillary tangles.

Since Alzheimer's first case was a middle-aged lady, it was assumed that this was a rare early onset or presenile dementia. However, studies in the United Kingdom in the 1960s demonstrated that the majority of elderly patients with dementia, which had previously been called senile dementia, were in fact suffering from Alzheimer's disease.

The key clinical feature of Alzheimer's disease is an early impairment of episodic memory, our memory for day-to-day events. Patients may have difficulty recalling what has happened to them; they forget to do things; they may misplace items; they repetitively question; and as the disease progresses, they may get lost. We all experience memory lapses from time to time, but it is the inexorable progression that identifies the patient with early Alzheimer's disease. After a period of a few years, other features supervene, with increasing difficulties with language and perception of the world. This pattern reflects the early involvement of the hippocampus, as explained previously, and other parts of the temporal lobe by the disease process.


It used to be thought that impairment of blood supply to the brain was the main cause of dementia. It was believed that hardening of the arteries, or atherosclerosis, led to a reduced blood flow. This has been disproved. While blood flow may be reduced in dementia, this is a consequence of the nerve-cell loss rather than a cause. What can cause dementia is recurrent large or small strokes and nerve-cell damage from disease in the small arteries to the central parts of the brain, called small-vessel disease or Binswanger's disease.

Patients with strokes can have significant problems with cognitive impairment, such as a patient with a right-sided paralysis accompanying loss of language or dysphasia. Multiple strokes can give rise to widespread cognitive impairment, but due to motor abnormalities, it is usually obvious that these are strokes and such patients rarely come to attention because of the cognitive impairment alone. Occasionally, a stroke in particular areas of the cerebral cortex or in the center of the brain (in the thalamus), can result in quite-widespread cognitive impairment.
