Cerebral Edema ll: Pathophysiology

31
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...

Hemorrhagic Stroke ll: Pathophysiology

57
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Hemorrhagic Stroke l: Introduction

41
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Cross-bridge Cycle01:26

Cross-bridge Cycle

108.9K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Alzheimer Disease ll: Pathophysiology

44
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...

Summary

Crossed cerebellar atrophy, a rare condition, results from damage to the opposite side of the brain. This atrophy may stem from disruptions in the corticopontocerebellar pathway above the tentorium.

Area of Science:

  • Neurology
  • Neuroscience
  • Cerebellar Diseases

Background:

  • Crossed cerebellar atrophy is an infrequent consequence of lesions in the contralateral cerebral hemisphere.
  • It has been observed following supratentorial infarcts, tumors, arteriovenous malformations, and hemorrhages.

Purpose of the Study:

  • To elucidate the underlying mechanisms of crossed cerebellar atrophy.
  • To investigate the relationship between supratentorial lesions and cerebellar degeneration.

Main Methods:

  • Review of existing literature on crossed cerebellar atrophy.
  • Analysis of case studies reporting supratentorial lesions and subsequent cerebellar changes.

Main Results:

  • Crossed cerebellar atrophy is consistently associated with contralateral supratentorial pathologies.
  • The condition highlights the interconnectedness of cerebral and cerebellar structures.

Conclusions:

  • The interruption of the corticopontocerebellar pathway at the supratentorial level is the likely cause of crossed cerebellar atrophy.
  • Understanding this pathway is crucial for diagnosing and managing cerebellar abnormalities.
