Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

748
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Diabetic Neuropathy

16
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...

Hemorrhagic Stroke ll: Pathophysiology

7
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...

Secondary Spinal Cord Injury llI: Pathophysiology

11
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...

Dementia l: Introduction

7
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...

Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

2
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...

Area of Science:

  • Neurology
  • Neurosurgery
  • Radiology

Background:

  • Subdural hemorrhage (SDH) is a significant cause of neurological morbidity.
  • Neurological presentations of SDH are diverse, but focal symptoms are common.

Observation:

  • Two elderly patients presented with isolated hand weakness.
  • Clinical presentation mimicked peripheral neuropathy, delaying SDH diagnosis.

Findings:

  • Subdural hemorrhage (SDH) can manifest with isolated hand weakness.
  • This atypical presentation can be misdiagnosed as peripheral neuropathy.

Implications:

  • Clinicians should consider subdural hemorrhage in elderly patients with unexplained hand weakness.
  • Prompt neuroimaging, such as CT scans, is crucial for diagnosing SDH in such cases.
  • Early diagnosis and treatment of SDH can prevent severe neurological deficits.
