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...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Summary

Friedreich's ataxia (FRDA) causes gray and white matter loss in the cerebellum and dorsal medulla. This brain atrophy correlates with disease duration and clinical severity.

Area of Science:

Neuroimaging
Neurology
Genetics

Background:

Neuropathological studies of Friedreich's ataxia (FRDA) predate current genetic diagnostic methods.
Voxel-based morphometry (VBM) offers unbiased, whole-brain quantitative analysis of gray matter (GM) and white matter (WM) volume changes.

Purpose of the Study:

To quantitatively assess brain structural damage in FRDA patients using VBM.
To correlate observed brain volume changes with disease duration and clinical severity.

Main Methods:

VBM analysis was performed on 22 genetically confirmed FRDA patients and 25 healthy controls.
Clinical deficits were evaluated using the International Cerebellar Ataxia Rating Scale and Inherited Ataxia Clinical Rating Scale.
Results were correlated with disease duration.

Main Results:

FRDA patients exhibited symmetrical GM and WM volume loss in the dorsal medulla, infero-medial cerebellum, rostral vermis, and dentate nucleus.
No significant volume loss was detected in the cerebral hemispheres.
Cerebellar and medullary atrophy correlated significantly with clinical deficit severity and disease duration.

Conclusions:

FRDA is characterized by significant GM and WM loss predominantly in the cerebellum and dorsal medulla.
These structural changes are directly associated with the clinical manifestations and progression of the disease.
