Alzheimer, a chronic neurodegenerative disease, usually starts slowly and worsens gradually. It causes 60% to 70% of dementia cases. Difficulty in remembering recent events (short-term memory loss) is the most prominent early symptom. As the disease progresses, patients may have problems such as impaired language, disorientation (including easily getting lost), mood swings, loss of motivation, ...

Early accurate detection of Alzheimer disease (AD) and its prognostic stage, i.e., Mild Cognitive Impairment (MCI) is getting more and more vital. A novel approach is applied for the diagnosis of very mild (CDR0.5) to mild (CDR-1) Alzheimer disease patients from normal controls combining morphometric features along with MMSE (Mini Mental State Examination) score. The combined features are fed i...

Alzheimer disease is characterized by a loss of cholinergic neurons in the basal forebrain and a decrease in acetylcholine levels. Currently, cholinesterase inhibitors, drugs that act by inhibiting the enzyme responsible for the hydrolysis of acetylcholine, are the only therapy for the treatment of Alzheimer disease approved by the Food and Drug Administration. The cholinesterase inhibitors hav...

Microglia are the principal immune cells of the brain. In Alzheimer disease, these brain mononuclear phagocytes are recruited from the blood and accumulate in senile plaques. However, the role of microglia in Alzheimer disease has not been resolved. Microglia may be neuroprotective by phagocytosing amyloid-b (Ab), but their activation and the secretion of neurotoxins may also cause neurodegener...

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 ...

Abstract Alzheimer’s disease (AD) is the most common cause of dementia in elderly people. The prevalence of Alzheimer diseases is increasing in the world due to population aging. Metabolic disease such as diabetes and obesity play important role in Alzheimer disease. Hyperglycemia can play important role in brain damage. It causes cognitive impairments, functional and structural alterations in...

the most popular animal models of alzheimer’s disease (ad) are transgenic mice expressing human genes with known mutations which do not represent the most abundant sporadic form of the disease. an increasing number of genetic, vascular and psychosocial data strongly support that the octodon degus, a moderate-sized and diurnal precocial rodent, provides a naturalistic model for the study of the ...
