Alzheimer's disease (AD) is histopathologically characterized by the presence of senile plaques, neurofibrillary tangles, and synapse loss. The main component of senile plaques is amyloid β-peptide (Aβ), which has been shown to induce oxidative stress in in vitro and in vivo studies. AD is...
In this article, we propose that impaired efficiency of glutamatergic synaptic transmission and a compensatory reduction in inhibitory neurotransmission, a process called homeostatic dishinhibition, occurs in the aging brain and more dramatically in Alzheimer's disease (AD). Homeostatic...
Alzheimer's disease (AD) and osteoporosis are common chronic degenerative disorders which are strongly associated with advanced age. Some studies suggest that low bone mineral density (BMD) is related to the increased risk of AD. We conducted a 5-year prospective study to exam the association...
Systematic studies on Alzheimer's disease (AD)-related pathology that complement clinical and epidemiological data on dementia from low and middle income countries are rare. We report the first large study on AD-related pathology in autopsy service-derived brains from an urban center in India, a...
In this paper, we argue that the current official definition for Alzheimer's disease is misleading, since it defines senile dementia (SD), a long-known incurable senile/geriatric condition, as a discrete/curable disease. This overly optimistic definition was incepted in the 1970s amid the...
Early symptoms of Alzheimer’s disease (AD) have been attributed to amyloid-β (Aβ) toxicity. The pathophysiology of AD is complex and involves several different biochemical pathways, including defective Aβ protein metabolism, neuroinflammation, oxidative processes, and mitochondrial...
Patients with Alzheimer's disease (AD) have heterogeneous rates of disease progression. The aim of the current study is to investigate whether neuropsychiatric disturbances predict cognitive and functional disease progression in AD, according to failure theory. We longitudinally examined 177...
