چکیده

Alzheimer’s disease (AD) is considered a slow neuronal dysfunction process through hypoxia, ischemia and leads to apoptosis mediated senile plaques and neurofibrillary tangles (NFTs). Due to non-invasive approach of plaque characterization, computational techniques based on Brownian dynamics simulation are unique to speculate the electrostatic and kinetic properties of Acetylcholinesterase (AChE). Typically the MRI spectroscopy high choline peak and enzyme specific to Alzheimer’s Disease (specificity constant (kcat/Km) of AChE) appeared associated with apoptosis and hypoxia. A simple display between synergy of cytokines, apoptosis, elevated AChE and choline is postulated as initial events. The events may be distributed heterogeneously within the senile plaques and neurofibrillary tangles (NFTs) of Alzheimer’s Disease (AD). The role of decreased brain AChE and synergy was associated with specific Magnetic Resonance Spectroscopic (MRS) pattern profiles in AD. These findings suggest that that the altered AChE and early apoptosis events in AD may be associated with specific MR spectral peak patterns. This study opens the possibility of reduced AChE levels causing high choline and reduced N-acetyl acetate (NAA) neurotransmitter by MRS after initial apoptosis and/or inflammation to make amyloid plaques in the cerebral tissue of Alzheimer’s disease (AD) patients. These results can be useful in clinical trials on AD lesions.

Vitamin E therapy prevents the accumulation of congophilic amyloid plaques and neurofibrillary tangles in the hippocampus in a rat model of Alzheimer’s disease

Objective(s): Vitamin E may have beneficial effects on oxidative stress and Aβ-associated reactive oxygen species production in Alzheimer’s disease. But, the exact role of vitamin E as a treatment for Alzheimer’s disease pathogenesis still needs to be studied. Hence, we examined the therapeutic effects of vitamin E on the density of congophilic amyloid plaques and neur...

The effect of flavonoids in the treatment of Alzheimer’s disease: review article

Alzheimer’s disease (AD) is the most prevalent age-related neurodegenerative disorder worldwide, and no cure or prevention has been found for it. Extracellular senile plaque and intracellular neurofibrillary tangles are two important histopathological hallmarks of AD, which are both harmful for the cell. Senile plaques are composed of amyloid beta and neurofibrillary tangles are formed by hyper...
