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...

Alzheimer Disease l: Introduction

Alzheimer Disease l: Introduction

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...

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...

Alterations in Muscle Tone lll

Alterations in Muscle Tone lll

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...

Background:

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with complex pathophysiology.
Identifying key metabolic alterations in ALS is crucial for developing effective treatments and diagnostic tools.

Purpose of the Study:

To identify metabolic pathways affected in ALS patients using non-targeted metabolomics.
To discover potential therapeutic targets and diagnostic biomarkers for ALS based on metabolic signatures.

Main Methods:

Cross-sectional studies involving plasma samples from ALS patients and healthy controls.
Global metabolic profiling to detect and evaluate biochemical signatures associated with ALS.
Statistical analysis to identify significantly altered metabolites in ALS patient plasma.

Main Results:

Twenty-three metabolites were significantly altered in plasma from ALS patients across both studies.
Altered metabolites are involved in pathways related to neuronal damage, hypermetabolism, oxidative stress, and mitochondrial dysfunction.
Evidence suggests potential hepatic dysfunction associated with ALS.

Conclusions:

Metabolomics analysis provides insights into ALS pathophysiology.
Identified metabolic alterations highlight potential therapeutic targets and diagnostic biomarkers for ALS.
This approach can generate novel hypotheses for future ALS research.
