background: alzheimer's disease as a neurodegenerative disorder is the commonest type of dementia. a growing number of genes have been reported as the risk factors, which increase the susceptibility to alzheimer's disease. apolipoprotein e ( apoe) , which its ε4 allele has been reported as a risk factor in late onset alzheimer's disease (ad), is the main cholesterol carrier in the brain. the ma...

alzheimer's disease (ad) is a chronic neurodegenerative disease that accounts for 60 to 80 percent of all dementia cases. the exact cause of alzheimer`s disease is still unknown, but recent studies suggest neuro-inflammation as an important part of the pathogenesis of the disease. this brings in mind using non-steroidal anti-inflammatory drugs (nsaid) as treatment or prevention of the dise...

neurodegenerative disease are characterized by the progressive loss of neurons from specific origins of the cns .alzheimer disease (ad) is a neurodegenerative disorder which affect brain regains that control memory and ability to learn. it is estimated that 27 million people are affected word wide and this number is expected to triple by 2050 due to increase of the population life expectancy. a...

background: despite the outbreak in dental science, oral and dental complications in alzheimer are of the unsolved problems. it is assumed that tumor necrosis factor-α, which is a key factor in alzheimer, has a relation with periodontal complications in patients with alzheimer disease. the present study evaluated the effect of chronic periodontitis on serum levels of tumor necrosis factor-α in ...

alzheimer disease (ad) is a neurodegenerative disorder marked by cognitive and behavioral impairment. amyloid beta (aβ) peptides are involved in ad as the main component of amyloid plaques found in the brain. recent in vivo and in vitro studies have shown that there is a lot of substances that alter aβ pathogenesis of ad. aβ induces toxicity lead to increasing ros. in the other hand, 5-ht6 and ...

conclusions both task-related and resting fmri techniques have the potential to detect early brain dysfunction related to ad. however, the use of fmri in ad populations thus far has been limited to a relatively small number of research groups. results bold fmri is considered to reflect the joined synaptic activity of neurons through mri signal changes because of alterations in blood flow, blood...

objectives: the aim of present study was to investigate the effect of cognitive rehabilitation, a new and non-pharmacological approach to reduce memory and other cognitive deficits in alzheimer's disease. methods & materials: this study was a quasi-experimental research, in singlesubject study-with control group- and based on an a-b design. that was conducted in two groups of control and e...
