Serum Levels of Homocysteine, Vitamin B12, and Folic Acid in Patients with Alzheimer’s Disease
Background: Alzheimer's disease is the most common form of dementia in the elderly. Serum levels of homocysteine have been related to increased cortical and hippocampal atrophy. We aimed to determine the serum levels of homocysteine, folate, and vitamin B12 in patients with Alzheimer's disease. Methods: Blood levels of homocysteine and its biological determinants, folate, and vitamin B12 were m...

متن کاملHippocampal Atrophy Studying in Alzheimer's Disease Diagnosis Using Brain MRI Images
Background and Aim: For effective treatment of Alzheimer's disease (AD), it is important to accurately diagnosis of AD and its earlier stage, Mild Cognitive Impairment (MCI). One of the most important approaches of early detection of AD is to measure atrophy, which uses various kinds of brain scans, such as MRI. The main objective of the current research was to provide a computerized diagnostic...
متن کاملThymoquinone recovers learning function in a rat model of Alzheimer’s disease
Objective: Alzheimer's disease is a neurodegenerative disorder characterized by accumulation of amyloid beta in the hippocampus. In recent decades, herbal medicine has been widely used to treat many neurodegenerative disorders,as in comparison to conventional drugs, herbal remedies exert minimal side effects. Here, the effects of thymoquinone, as the main active component of Nigella sativa, on ...
متن کاملThe beneficial effects of riluzole on GFAP and iNOS expression in intrahippocampal Aβ rat model of Alzheimer’s disease
Background and Objective: Alzheimer’s disease (AD) is a neurodegenerative disorder specified by deposition of b-amyloid (Ab) and neuronal loss that leads to learning and memory disturbances. One of the most important causes of AD is glutamate-dependent excitotoxicity in brain regions that is vulnerable to AD. According to previous reported results, it was revealed that riluzole, as a glutamate ...
