Apraxia and Alzheimer's Disease: Review and Perspectives.
Summary of "Apraxia and Alzheimer's Disease: Review and Perspectives."
Apraxia is one of the cognitive deficits that characterizes Alzheimer's disease. Despite its prevalence and relevance to diagnosing Alzheimer's disease, this topic has received little attention and is without comprehensive review. The review herein is aimed to fill this gap by first presenting an overview of the impairment caused in different clinical situations: pantomime of tool use, single tool use, real tool use, mechanical problem solving, function and manipulation knowledge tasks, and symbolic/meaningless gestures. On the basis of these results, we then propose alternative interpretations regarding the nature of the underlying mechanisms impaired by the disease. Also presented are principal methodological issues precluding firm conclusions from being drawn.

Several reports suggest that the reelin protein could play a role in Alzheimer pathophysiology. This led us to ask whether genetic variability in the reelin pathway may increase the risk of developing...
We describe a patient with corticobasal syndrome in whom neuropathological examination on autopsy revealed Pick and Alzheimer diseases in comorbidity. Corticobasal degeneration is a tauopathy usually...
Chagas disease (CD), also known as American trypanosomiasis, is caused by the flagellated protozoan Trypanosoma cruzi, and affects an estimated 8 to 10 million people worldwide. In Latin America, 25 m...
Although vitamin E and memantine have been shown to have beneficial effects in moderately severe Alzheimer disease (AD), evidence is limited in mild to moderate AD.
The global prevalence of dementia is as high as 24 million, and has been predicted to quadruple by the year 2050. In the US alone, Alzheimer disease (AD) - the most frequent cause of dementia characte...
The purpose of this study is to identify potential biomarkers that may predict the development of Alzheimer's disease in people who carry an Alzheimer's mutation.
ALADDIN is a research study to investigate the safety and effectiveness of leuprolide (a hormone drug) to improve the cognitive function and slow the progression of Alzheimer's disease (AD...
The purpose of this study is to test if the investigational medication ABT-089 is a safe and effective treatment for Alzheimer's disease.
The purpose of this observational study is to examine patterns of treatment care for patients with Alzheimer's disease in a real-world arena and to examine the association with different o...
The purpose of this study is to learn whether treating individuals with Alzheimer's disease and depression with the anti-depressant medication sertraline (Zoloft) is helpful to people with...
Medical and Biotech [MESH] Definitions
Impaired ambulation not attributed to sensory impairment or motor weakness. FRONTAL LOBE disorders; BASAL GANGLIA DISEASES (e.g., PARKINSONIAN DISORDERS); DEMENTIA, MULTI-INFARCT; ALZHEIMER DISEASE; and other conditions may be associated with gait apraxia.
Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER DISEASE. Neuropil threads are made up of straight and paired helical filaments which consist of abnormally phosphorylated microtubule-associated tau proteins. It has been suggested that the threads have a major role in the cognitive impairment seen in Alzheimer disease.
Vaccines or candidate vaccines used to prevent or treat ALZHEIMER DISEASE.
Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment.
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE.
