As a whole the promise behind the uses of both fMRI and sMRI as biomarkers for determining and testing brain activity in individuals at risk for Alzheimer disease or already suffering from Alzheimer’s disease is great. Separately neither sMRI nor fMRI hold an advantage over the other when it comes to being used as biomarkers for Alzheimer’s disease. This is because they really measure two separate things within the same structure. sMRI measures the anatomy and pathology of the brain where fMRI measures and examines brain activity. However, the two used in combination with each other are far more advantageous and allows clinicians to track changes in brain structures anatomically and functionally over time as a whole. When it comes to†¦show more content†¦These areas are monitored because Alzheimer’s Disease, a form of dementia, is due to degenerative atrophy of neurons and synapses which cause decreases in activity, functionality, and size, within these areas. This is why Alzheimer’s Disease is bookmarked by memory loss, confusion, disorientation about time and place, poor judgment, and changes in mood, behavior, and personality. However, when it comes to the use of sMRI and fMRI as biomarkers for determining and testing brain activity in individuals at risk for Alzheimer disease the validity of their use is not so straight forward. Making an accurate diagnosis of Alzheimer’s Disease during the early stages of the disease is a hard one to make. Which means making an accurate diagnosis before any clinical symptoms occur is extremely hard. This is why the majority of biomarkers including sMRI and fMRI are only available as a research tool and are not yet accepted in clinical practice when it comes to diagnosing patients before the onset of any clinical symptoms. With the little success Alzheimer’s Disease medications/interventions have had, many researchers have shifted their focus to a new population group. The new population group is patients who do not yet exhibit Alzheimer’s symptoms but whose brains physically show possible pre-Alzheimer’s disease precursors. Researchers want to see if they can find some kind of common deterioration in brain function and structure in pre-Alzheimer’sShow MoreRelatedThe Selection Criteria For These Patients1500 Words   |  6 PagesAnalysis This study sought to find specific neural differences between bipolar patients with a history of delusions versus those without, and it was seemingly successful in doing so. However, before we can accept the results at face value we must first understand the benefits and the limitations of the methodology in order to put the results into context. The study was generally well designed and its findings are for the most part coherent to other literature in the field.

There are still teens who either did not want to participate or who are not having any form of sexual activity. From the statistic we can confer that education about sexual health is something that is not being administered in schools and thus willRead MoreThe Effects Of Anterograde Amnesia And Its Diagnostic Criteria2724 Words   |  11 Pagesas other forms of amnesia, but it is still incorrectly portrayed. Anterograde amnesia refers to the inability to retain new information, while still having intact memories that occurred before brain damage (Carlson, 2014). There have been several studies that focus on anterograde amnesia and its diagnostic criteria, course, associated features, assessment, etiology, underling neurobiological mechanisms, treatments, and future research. Researchers mention that there are two forms of long term memoryRead MoreMandatory Minimum Sentencing For The United States Essay1751 Words   |  8 PagesInstitute (SMRI) and founder of the Treatment Advocacy Center (TAC), says â€Å"Between 1980 and 1995, the total number of individuals incarcerated in American jails and prisons increased from 501,886 to 1,587,791, an increase of 216 percent.
