Amyloid Fibrils

10.1K
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,...

Alzheimer Disease ll: Pathophysiology

27
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...

Alzheimer Disease l: Introduction

19
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Alzheimer's Disease: Overview

1.7K
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...

Dementia l: Introduction01:22

Dementia l: Introduction

29
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
This summary is machine-generated.

Senile systemic amyloidosis (SSA), linked to aging, involves transthyretin amyloid deposition in the heart, causing heart failure. Carpal tunnel syndrome in older adults may indicate early SSA, warranting diagnostic confirmation.

Area of Science:

  • Cardiology
  • Geriatrics
  • Neurology

Context:

  • Senile systemic amyloidosis (SSA) is an age-related condition.
  • Characterized by wild-type transthyretin amyloid fibril deposition.
  • Primarily affects the myocardium, leading to heart failure and arrhythmias.

Purpose:

  • To highlight the evolving understanding of SSA onset and presentation.
  • To emphasize carpal tunnel syndrome (CTS) as a potential early indicator of SSA.
  • To discuss emerging therapeutic strategies for SSA.

Summary:

  • SSA, previously considered a disease of the very elderly, now shows earlier onset around age 50.
  • Carpal tunnel syndrome (CTS) frequently precedes cardiac symptoms in SSA patients.
  • Confirmation of amyloid deposits in CTS surgery specimens from patients over 50 is recommended.

Impact:

  • Early identification of SSA through CTS screening can lead to timely intervention.
  • Understanding the broader age range and early symptoms of SSA improves diagnostic rates.
  • Potential application of transthyretin-stabilizing drugs (e.g., tafamidis) offers new hope for SSA treatment.
