CASE STUDY

Allie, a 72 year old lady was brought to see a
neuropsychologist for an evaluation of memory loss
of a progressive nature. The symptoms had been
present for years and were getting worse. Her
memory loss originally took the form of a tendency
to repeat questions and ideas. As the symptoms
progressed, her son, reported that her mother was
having trouble reasoning and was disoriented with
regards to time, day, month and year. Frequently,
Allie did not understand were she was when outside
of home.
CASE STUDY
Her son described that his mother is still
experiencing anxiety and depression, which was
signified a personality change in her mother despite
multiple courses of medication for depression. She
is now also tended to be overall aggressive towards
others, which was not her usual manner. In
addition, her son reported that his mother had
begun to require supervision in dressing, bathing,
and grooming and required reminders to change
his clothes. Frequently, Allie would wear the same
clothes repeatedly. It was also noted that she had
become socially withdrawn.
CASE STUDY

During the doctor’s evaluation, she was very
upset when she was examined, because she did
not comprehend why she was there.
Throughout the visit, she had difficulty finding
words. Even without any other medical or
neurological evaluations, all these indications
made it obvious to the neuropsychologist that
she had classic Alzheimer’s disease in the
moderately severe stages.

PATHOPHYSIOLOGY
3 HALLMARKS OF AD:
1. Beta-amyloid plaques
- Composed of degenerating axons and
   dendrites.
- Dense deposits of protein & cellular material

LATEST RESEARCH REGARDING AD:
Medscape Medical News reported on the latest published
research in Alzheimer’s disease on November 7, 2012 indicating
individuals carrying a mutant gene for Alzheimer’s disease
demonstrate markers 20 years before onset of memory changes.
In addition to markers in the cerebral spinal fluid, the individuals
show structural changes in the brain other than the amyloid
plaques and tangles commonly found in patients with the disease.

Dr. Eric M. Reiman, the first author on this recent study,
published his results in Lancet Neurology on November 6, 2012.
His research group from the Banner Alzheimer’s Institute in
Phoenix, Arizona studied about 5000 people who carry the gene
mutation that produces Alzheimer’s disease as early as age 45
years in Colombia.
Reiman and colleagues compared carriers of the gene with non-carriers
and found structural differences in area of the brain called the
hippocampus as well as less grey matter in some parietal lobes in
individuals with the Alzheimer’s gene mutation. The parietal lobe
resides at the top of the head after the frontal lobe and before the
occipital lobe at the back of the head. The researchers used magnetic
resonance imaging to uncover the changes in the parietal lobe. These
changes occurred 20 years before the onset of memory loss. By
knowing these alterations exist early, researchers can study treatments
and measure for differences at these sites.
According to the Center for Disease Control and Prevention,
Alzheimer’s disease causes the most common form of dementia that
produces loss of thought control, memory and language. The disease
usually affects men and women over the age of 60 years. The cause of
Alzheimer’s disease remains presently unknown. Most scientists think
several factors such as genetic, environmental and lifestyle contribute
to the development of the disease. The discovery of changes in the
parietal lobe and hippocampus add significantly to progress in the
research.
The National Institute on Aging describes the
importance of clinical research for uncovering causes,
treatment modalities and disease prevention in
Alzheimer’s disease. Patients or families interested in
becoming involved in research trials can go the Clinical
Trials.gov website for more information. The research
trial website lists trials available in all 50 states and 181
countries.

Ethical Considerations
     Ethical Issues in the Early Diagnosis of Alzheimer Disease
     Matthew E. Growdon

     Mattsson N, Brax D, Zetterberg H. To know or not to know: ethical issues related to early diagnosis of
     Alzheimer’s disease. Int J Alzheimers Dis. 2010.


     While a disease-modifying treatment for Alzheimer disease (AD) remains elusive, recent advances have shed light
     on its pathophysiology, giving patients and researchers alike hope that a viable treatment will emerge. Research
     efforts have identified promising drug targets for clinical trials and uncovered cerebrospinal fluid (CSF) biomarkers
     and imaging studies that allow for preclinical detection of AD pathology. The recognition that the hallmark plaques
     and tangles of AD are detectable in the brains of individuals more then 10 years before they present with any
     cognitive changes underscored the need to validate biomarkers that could reliably detect AD and chart its
     progression.

     In April 2011, the Alzheimer’s Association [1] updated the criteria for the diagnosis of Alzheimer’s disease
     dementia for the first time in 27 years. Their report emphasizes biomarker data and lays out research guidelines
     for the preclinical diagnosis of AD meant to facilitate ongoing clinical research and drug discovery efforts [2].

     Implicit in these new guidelines is the hope that effective therapies are around the corner and the belief that
     interventions should be designed for individuals before their brains are irreversibly damaged. The well-placed
     optimism of scientific progress can obscure the humanistic dimensions of early diagnosis. In “To Know or Not to
     Know: Ethical Issues Related to Early Diagnosis of Alzheimer’s Disease,” Niklas Mattsson, David Brax, and Henrik
     Zetterberg examine the ethical issues surrounding the early diagnosis of AD. They emphasize the potentially
     harmful consequences of early diagnosis to the patient and raise important questions about personal identity and
     decision-making competence that are central to the diagnosis and management of AD. Their article is a timely
     reminder about the powerful, life-altering effects of diagnosis and, above all, the enduring need to place the
     patient’s desires and preferences at the center of the clinical encounter.

     As a point of departure, Mattsson et al. consider the potential for misdiagnosis of AD, even in the era of
     sophisticated biomarker studies. Several studies underscore the high diagnostic accuracy of cerebrospinal fluid
     (CSF) biomarkers, with sensitivity and specificity around 85-90 percent in identifying incipient AD in patients
     diagnosed with mild cognitive impairment, an intermediate stage between the expected cognitive decline of
     normal aging and the pronounced decline of dementia [3].

     However, the authors acknowledge the enduring possibility of misdiagnosis in populations or samples in which
     there is a low prevalence of disease because of false positive screening results. Furthermore, while severe
     complications are rare, lumbar punctures to obtain CSF are associated with post-LP headaches in 2-4 percent of
     patients [4]. Colloquially referred to as “spinal taps,” lumbar punctures are feared by many patients, to the point
     that there have been calls within professional circles to rename the procedure and move it into the mainstream of
     clinical practice in dementia care [5].

Most scientists think several factors such as genetic, environmental and lifestyle contribute to the development of the disease. The discovery of changes in the parietal lobe and hippocampus add significantly to progress in the research.

To know or not to know: ethical issues related to early diagnosis of Alzheimer’s disease. Int J Alzheimers Dis. 2010. While a disease-modifying treatment for Alzheimer disease (AD) remains elusive, recent advances have shed light on its pathophysiology, giving patients and researchers alike hope that a viable treatment will emerge. Research efforts have identified promising drug targets for clinical trials and uncovered cerebrospinal fluid (CSF) biomarkers and imaging studies that allow for preclinical detection of AD pathology. The recognition that the hallmark plaques and tangles of AD are detectable in the brains of individuals more then 10 years before they present with any cognitive changes underscored the need to validate biomarkers that could reliably detect AD and chart its progression. In April 2011, the Alzheimer’s Association [1] updated the criteria for the diagnosis of Alzheimer’s disease dementia for the first time in 27 years. Their report emphasizes biomarker data and lays out research guidelines for the preclinical diagnosis of AD meant to facilitate ongoing clinical research and drug discovery efforts [2]. Implicit in these new guidelines is the hope that effective therapies are around the corner and the belief that interventions should be designed for individuals before their brains are irreversibly damaged. The well-placed optimism of scientific progress can obscure the humanistic dimensions of early diagnosis. In “To Know or Not to Know: Ethical Issues Related to Early Diagnosis of Alzheimer’s Disease,” Niklas Mattsson, David Brax, and Henrik Zetterberg examine the ethical issues surrounding the early diagnosis of AD. They emphasize the potentially harmful consequences of early diagnosis to the patient and raise important questions about personal identity and decision-making competence that are central to the diagnosis and management of AD. Their article is a timely reminder about the powerful, life-altering effects of diagnosis and, above all, the enduring need to place the patient’s desires and preferences at the center of the clinical encounter. As a point of departure, Mattsson et al. consider the potential for misdiagnosis of AD, even in the era of sophisticated biomarker studies. Several studies underscore the high diagnostic accuracy of cerebrospinal fluid (CSF) biomarkers, with sensitivity and specificity around 85-90 percent in identifying incipient AD in patients diagnosed with mild cognitive impairment, an intermediate stage between the expected cognitive decline of normal aging and the pronounced decline of dementia [3]. However, the authors acknowledge the enduring possibility of misdiagnosis in populations or samples in which there is a low prevalence of disease because of false positive screening results. Furthermore, while severe complications are rare, lumbar punctures to obtain CSF are associated with post-LP headaches in 2-4 percent of patients [4]. Colloquially referred to as “spinal taps,” lumbar punctures are feared by many patients, to the point that there have been calls within professional circles to rename the procedure and move it into the mainstream of clinical practice in dementia care [5].
