Introduction: Donepezil (DON), an Acetylcholinesterase Inhibitor (AChEI), is widely used in the treatment of Alzheimer’s Disease (AD). The current study aimed at evaluating the effect of donepezil hydrochloride on pyramidal neuron response in CA1 region of a rat model of AD. Methods: In the current experimental study, adult male Wistar rats were randomly divided into four groups: Nucleus Basal...

objective(s): alzheimer's disease (ad) is a neurodegenerative disorder in elderly patients. decrease in cholinergic neurotransmission is the main known cause in the pathophysiology of the disease. improvement and potentiation of the cholinergic system could be beneficial for treatment of the ad. acetylcholinesterase inhibitors such as donepezil can enhance the duration of action of acetylc...

Alzheimer’s disease (AD) is a neurodegenerative disorder and the most common form of dementia. Almost 47 million people suffer from dementia worldwide. AD accounts for approximately 60%–80% of all dementia cases. Three major pathologies characterize the disease: senile plaques, neurofibrillary tangles and inflammation. We review the literature on events contributing to the inflammat...

Background: Alzheimer’s disease (AD) is the most prevalent degenerative disorder of the brain among elderly individuals. Many studies indicate that oxidative stress is an important pathogenic factor which involves oxidizing macromolecules such as DNA, lipids, and proteins in AD. Green tea is a rich source of antioxidant compounds that can remove radical oxygen species. The purpose of this...

In 2016, scientists reported that human exposure to low doses of ionizing radiation (CT scans of the brain) might relieve symptoms of both Alzheimer’s disease (AD) and Parkinson disease (PD). The findings were unbelievable for those who were not familiar with neurohormesis. X-ray stimulation of the patient’s adaptive protection systems against neurodegenerative diseases was the mechanism pr...

background: alzheimer’s disease (ad) is a progressive neurodegenerative disease and nowadays the role of endothelial cell (ec) injury has been proposed in pathological process in ad. peroxisome proliferator‑activated receptor‑γ (ppar‑γ) agonist has anti‑inflammatory properties through activation in glial cells and improves vascular function and prevent atherosclerotic disease progression. the a...

alzheimer's disease (ad), the most ordinary form of dementia and extracellular accumulation of amyloid-β (aβ) in senile plaques, is an important and a main event in the pathogenesis of ad. deposition of aβ peptide initiates a spectrum of cellular responses that are interposed by the resident neuroimmune cells of the brain, the microglia. recently, a novel inflammasome signaling  pathway ha...

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 disease. ...

progressive cognitive decline is one of the hallmark symptoms of alzheimer’s disease (ad) which can be modeled by β-amyloid injection into specific regions of brain. since epigallocatechin-3-gallate (egcg) is a potent antioxidant agent which its role against oxidative stress and inflammation has been shown in prior studies, we tried to determine whether egcg administration protects against β-am...
