Alzheimer Disease ll: Pathophysiology

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...

Amyloid Fibrils

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

Parkinson Disease ll: Pathophysiology

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

Summary

Beta-amyloid (Abeta) may accelerate neurofibrillary tangle (NFT) formation in Alzheimer's disease (AD). This review explores four mechanisms linking Abeta to tau pathology, driving AD neurodegeneration.

Background:

Alzheimer's disease (AD) is characterized by amyloid plaques and neurofibrillary tangles (NFTs).
The relationship between beta-amyloid (Abeta) and tau proteins in AD pathogenesis remains incompletely understood.

Observation:

A growing body of evidence suggests Abeta interacts with tau, promoting NFT formation.
Abeta influences molecular and cellular pathways, leading to tau phosphorylation, aggregation, and mis-localization.

Findings:

Four mechanisms link Abeta to tau pathology: kinase activation, inflammation, impaired proteasomal degradation, and disrupted axonal transport.
Abeta may enhance tau hyperphosphorylation and NFT formation via kinase activation.
Inflammatory responses and cytokines in the AD brain can modulate tau phosphorylation.

Implications:

Understanding Abeta-tau interactions is crucial for developing effective Alzheimer's disease therapies.
Targeting these pathways could offer novel therapeutic strategies for AD.
Elucidating these mechanisms may lead to earlier diagnosis and intervention for AD.
