When is a 100% accurate diagnosis of Alzheimer's disease possible ? 1 ) after the first two symptoms have occurred 2 ) after a blood test has detected antibodies for the disease 3 ) after a brain biopsy when the individual is alove 4 ) after an autopsy when the individual is dead

Step 1
- Option 1 suggests diagnosis after the first two symptoms have occurred. However, symptoms of Alzheimer's can be similar to those of other conditions, making a diagnosis based solely on symptoms less reliable. - Option 2 mentions a blood test detecting Show more…

A recent ScienceDaily article talked about a possible new early diagnostic test for Alzheimer's disease (AD). All of the statements below are true except: Select One: The eye test is based upon the accumulation of beta-amyloid plaques. The test shows increased pupil dilation as a possible indicator of AD. Tau protein tangles are the earliest indications of AD. The brain region associated with the pupillary response is the locus coeruleus.

Questions Exactly what is Alzheimer's disease? Is it the same as EOFAD? After looking at the PET scans in Figures 1 and 2 below and doing some reading in the textbook (Nussbaum, 2007), discuss how the brain is affected and how this leads to particular symptoms in Alzheimer's disease. Evaluate the information in the third paragraph of the narrative. Do you think EOFAD qualifies as a multifactorial disease? List your reasons below. Part II - Another story In the case study 4 in the textbook, there is a story about Alzheimer's disease with a different narrative. Read the "history and physical finding" and fill in the following table that contrasts the two cases. Suzanne's case L.W.'s case Onset of the disease in family member Symptoms Affected gene Questions: In Suzanne's case, she knew her risk of having EOFAD before she had any symptoms. If she had the genetic test which confirms the presence of the allele, there is a high chance that she will have the familial Alzheimer's disease. However, L.W.'s diagnosis was not confirmed until her death, eight years after she developed dementia. What has contributed to the lack of certainty or prediction in L.W.'s case? The apolipoprotein E gene (APOE) encodes for a protein in the lipid metabolism. Various alleles have been identified in the general populations (Table 12-10). Alzheimer's disease is positively associated with some allele combinations whereas is negatively associated with other allele combinations (Table 8-7). Study these tables and answer the following questions. According to the tables, which allele is positively (increases the risk) associated with the development of Alzheimer's disease? What are the control groups in these studies? The frequency of all three genotypes with Æ4 is 0.64 in AD patients and 0.31 in the control group in the United States; 0.47 in AD patients and 0.17 in the control group in Japan. Interpret these data. L.W. has the genotype Æ4/Æ4. According to Table 12-10, she has a 30-50% genetic risk for Alzheimer's disease, known as the late-onset Alzheimer's disease (LOAD) which typically develops after 60 years old. Is LOAD a complex disease? Present all your supporting arguments. Part III - How about the risk factors? What information provides further evidence that the environment affects the development of Alzheimer's disease? List them all here.

5. What statement BEST explains why eating disorders are less common in males than in females? Compared with females, males are less concerned with how they are judged by others. Eating disorders are overdiagnosed in females. Males are less susceptible to brain chemistry changes than females are. Males are more likely to achieve weight loss through exercise than through dieting. 6. Which statement about Alzheimer's disease is TRUE? It can be treated with a combination of antianxiety and antipsychotic medications. Its onset typically occurs prior to age 65. It is currently incurable and difficult to treat. Most people diagnosed with Alzheimer's disease die from it within a year after being diagnosed. 12. When is bulimia nervosa or anorexia nervosa most likely to begin? at the legal age to create social media accounts and engage with others online at the onset of puberty, when bodies change and begin taking on a more adult form upon entry into college, when fear of the "freshman fifteen" becomes overwhelming after a period of intense dieting that has been successful and has earned praise from others 15. The symptoms of vascular neurocognitive disorder: develop slowly begin suddenly. are silent. develop in the same way as those for Alzheimer's disease. 17. Which is NOT a personality tendency that would be included in the newly proposed diagnosis that is called personality disorder—trait specified (PDTS)? manipulativeness attention seeking hostility sexual promiscuity 18. Which person would be MOST likely to cut out sweets, then eliminate more and more types of foods, but not engage in forced vomiting? someone experiencing restricting-type anorexia nervosa someone experiencing purging-type anorexia someone experiencing bulimia nervosa someone experiencing acute-type bulimia 20. Among elderly persons who would benefit from mental health services, MOST: do not get the treatment they need. see a mental health care provider but are noncompliant with their treatment plans. resist using these services even when opportunities are available. seek services from those who are not qualified to offer effective treatment.
