Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

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 barrier loses...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Alterations in Muscle Tone ll01:12

Alterations in Muscle Tone ll

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
Cytotoxic Edema: Pathophysiology01:21

Cytotoxic Edema: Pathophysiology

Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...

This summary is machine-generated.

Normal pressure hydrocephalus is an uncommon cause of chorea, a movement disorder. This case report highlights that treating hydrocephalus with shunt placement can significantly improve chorea symptoms.

Area of Science:

  • Neurology
  • Neurosurgery

Background:

  • Chorea is a movement disorder with diverse etiologies.
  • Diagnostic challenges exist in identifying the underlying cause of chorea.
  • Hydrocephalus, particularly normal pressure hydrocephalus, is not typically recognized as a cause of chorea.

Purpose of the Study:

  • To report an unusual case of chorea secondary to normal pressure hydrocephalus.
  • To highlight normal pressure hydrocephalus as a potential, albeit rare, cause of chorea.
  • To demonstrate the efficacy of surgical intervention for this condition.

Main Methods:

  • Case report of a patient presenting with chorea.
  • Diagnostic workup including neuroimaging to identify potential causes.
  • Treatment involved cerebrospinal fluid shunt placement for normal pressure hydrocephalus.

Main Results:

  • The patient exhibited chorea as a primary symptom.
  • Normal pressure hydrocephalus was diagnosed as the underlying cause.
  • Significant improvement in chorea was observed following shunt placement.

Conclusions:

  • Normal pressure hydrocephalus should be considered in the differential diagnosis of unexplained chorea.
  • Cerebrospinal fluid shunting can be an effective treatment for chorea caused by normal pressure hydrocephalus.
  • This case expands the known spectrum of clinical presentations associated with normal pressure hydrocephalus.
