All rights reserved. Normal pressure hydrocephalus (NPH) is considered to be potentially treatable with the placement of a cerebrospinal fluid (CSF) shunt. Profiles of domain-specific function were analysed using three composite scales, Verbal Memory, Executive Function and Nonverbal Memory. These were the hypotheses to be tested in autopsy defined cases: (i) cerebrovascular disease is associated with deficits of executive function that are more severe than episodic memory deficits; (ii) Alzheimer's disease is associated with episodic memory impairments that are more severe than executive function deficits; (iii) neuropathological markers of Alzheimer's disease correlate with episodic memory function; and (iv) neuropathological markers of cerebrovascular disease correlate with executive function. It is not likely that the modest association between vascular pathology and executive dysfunction is simply a measurement problem. “AR activity,” the scientists added, “is increased in the brain and other organs with aging. This study evaluated the idea that the neuropathological changes of Alzheimer's disease and subcortical cerebrovascular disease cause distinctive, dissociable patterns of neuropsychological impairment such that memory failure is predominant in Alzheimer's disease, and executive dysfunction is predominant in subcortical cerebrovascular disease. Even in the case when an ischaemic event is followed closely by a decline in function, it can be difficult to be certain that the clinical picture does not reflect a potentiation of underlying Alzheimer's disease. This observation has led to the suggestion that predominant cognitive executive dysfunction might serve as a useful diagnostic marker for vascular dementia. Subjects were 62 autopsied cases from a prospective study of vascular contributions to dementia. The main effect for group was significant [F(3,53) = 7.5, P = 0.0003] as were the main effect for scale [F(2,51) = 9.0, P = 0.0005] and the group × scale interaction [F(3,53) = 6.5, P = 0.0008]. In contrast, the distribution for CVD is less distinctive: although Low Memory described only 18% of cases and Low Executive is the most common profile, Low Executive described less than half (45%) and 36% of cases fit neither pattern. Author information: (1)Department of Psychiatry. The Mixed cases had the essentially the same predominance of Low Memory profiles as did the AD cases (67%), and Low Executive was modestly more common (22%) than in AD (10%). Donor items for Executive Function consist of working memory and verbal fluency items and the Initiation—Perseveration subscale from the DRS, and Nonverbal Memory uses items from the Biber serial design learning test (Glosser, 1989). There are several major methodological strengths of the present study.
It may be, for example, that effects of vascular pathology are more pronounced in mild cognitive impairment than in normal or demented cases. Hippocampal sclerosis (HS), defined as segmental neuronal dropout and gliosis in the pyramidal cell layer, was rated on a 0–3 scale. It can, however, be overactivated if too much fructose is consumed. Add to Likebox #47589501 - healthcare infographic about early signs of alzheimers disease. Brain comorbidities in normal pressure hydrocephalus. Low Executive was nearly as common in NEB (39%) as in CVD (45%). Additionally, all cases were evaluated under a single neuropathology protocol that involved an extensive evaluation of vascular lesions, and all cases were reviewed by multiple neuropathologists who made cases ratings at consensus case conference. The term subcortical cerebrovascular disease is used here to refer to the clinical presentation in which subcortical infarcts and white matter changes, but not large cortical infarcts are evident. Similar Images . Although neuropsychological domains other than memory and executive function have been examined as potentially differing between Alzheimer's disease and vascular dementia, we chose these for two main reasons. Please enable it to take advantage of the complete set of features! Learn how your comment data is processed. Theoretically, regulating KHK-C in the brain, or regulating AMP deaminase-2 (which removes AMP, thereby reducing the ability of the cell to replenish ATP levels), might provide novel ways to prevent and treat Alzheimer’s disease.”. The critical problem with all such studies is the lack of neuropathological confirmation of clinical diagnosis. Within the item response theory framework, scales are matched when they demonstrate equivalent reliability (test information values) over a similar range of measured ability (theta). The Brain and Alzheimer's Disease During the past few decades, a great deal has been learned about the changes that occur in the brain of individuals who have late-onset Alzheimer's disease. 2020 Jun 1;20(1):273. doi: 10.1186/s12888-020-02690-1.
Autopsy studies of patients with NPH during their lifetime would elucidate the frequency of such comorbidities. Strong negative correlations were found between Braak stage and scores on Verbal Memory (R2 = 0.20, P < 0.0002), Nonverbal Memory (R2 = 0.21, P < 0.0002) and between CERAD score and Verbal Memory (R2 = 0.21, P < 0.0002) and Nonverbal Memory (R2 = 0.25, P < 0.0001).
In practice, the project neuropathologists have judged 20 to be a score that reflects substantial ischaemic pathology. Thus, cases were classified as pathology-defined Alzheimer's disease when the likelihood of Alzheimer's disease was ‘high’ or ‘moderate’ by NIA-Reagan Institute criteria unless the CVDPS score was 20 or higher in which case a diagnosis of Mixed pathology applied.
