Literature Review Dementia

Literature Review

According to Gavett and Stern (2012), instead of being a continuous variable, dementia epitomizes the ultimate common clinical pathway for a number of advanced (e.g., chronic traumatic encephalopathy, AD, frontotemporal lobar degeneration) and revocable (e.g., vitamin B12 deficiency, major depression, hypothyroidism) medical conditions. It is believed that the construct of dementia is best hypothesized as continually fluctuating however, evidence is showing dementia is divergent and definite. The simple fact of the presence of dementia does not give insight into its cause. From a developmental perspective of aging, knowing whether the inactive structure of dementia is unqualified or continuous does not appear to provide

Leukoaraiosis, viewed as cerebral white matter hyperintensities (WMH) on magnetic resonance imaging (MRI) or low attenuation on computed tomographic scanning (CT), is common in patients with dementia. They have found a failure of elimination of interstitial fluid (ISF) from white matter, particularly connected with cerebral amyloid angiopathy (CAA). Pathological studies and discovery of expanded perivascular spaces (PVS) by MRI in the white matter. Whereas, failure of eradication of ISF from the aging brain specifies failure in the disposal of soluble metabolites from the brain, where consequently there is a failure of homeostasis of the neuronal setting with significant consequences for the pathogenesis of dementia (Weller et al.,

The task performances of the dementia group were demonstrated by pointedly more unproductive actions, omission errors, and substitution errors when compared with younger adult and old age groups. Further, the dementia group engaged in considerably more irrelevant task actions (i.e., task actions, not related to the task at hand). Generally, the errors made by the dementia group expansively compromised their ability to complete the everyday tasks with accuracy. In many cases, alternate task actions were completed, alternate objects were used to complete tasks, and tasks were ended prematurely, or they performed irrelevant behaviors (Schmitter-Edgecombe and Parsey,
