Effect of Long-term Exposure to Extremely Low-frequency Electromagnetic Fields on β-amyloid Deposition and Microglia Cells in an Alzheimer Model in Rats

Background: Recently, researchers have considered extremely low-frequency electromagnetic fields (ELF-EMFs), as one of the non-invasive therapies, in the treatment of many severe neurological disorders, including Alzheimer Disease (AD). AD is a progressive neurodegenerative disease characterized by the deposition of amyloid plaques in the brain. However, the increase in microglial cells increas...

Non-inflammatory cerebral amyloid angiopathy as a cause of rapidly progressive dementia: A case study

A 77 year-old men developed a subacute-onset, rapidly progressive cognitive decline. After 6 months of evolution, he scored 6 on the Mini-Mental State Examination and had left hemiparesis and hemineglect. The patient died 11 months after the onset of cognitive symptoms. Brain MRI showed microhemorrhages on gradient-echo sequence and confluent areas of white matter hyperintensities on T2-weighte...

Cognitive consequences of thalamic, basal ganglia, and deep white matter lacunes in brain aging and dementia.

BACKGROUND AND PURPOSE Most previous studies addressed the cognitive impact of lacunar infarcts using radiologic correlations that are known to correlate poorly with neuropathological data. Moreover, absence of systematic bilateral assessment of vascular lesions and masking effects of Alzheimer disease pathology and macrovascular lesions may explain discrepancies among previous reports. To defi...

Cholinergic neuropathology in a mouse model of Alzheimer's disease

Transgenic mice over-expressing mutant human amyloid precursor protein (PDAPP mouse) develop several Alzheimer’s disease (AD)-like lesions including an age-related accumulation of amyloid-?-containing neuritic plaques. Although aged, heterozygous PDAPP mice also exhibit synaptic and glial cell changes, that is characteristic of AD pathology, no evidence of neurodegeneration has been observed. T...
