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...

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Dementia l: Introduction01:22

Dementia l: Introduction

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...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Alzheimer Disease l: Introduction01:29

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...
Traumatic Memory01:20

Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual remembers mundane...

Area of Science:

  • Neuroscience
  • Sports Medicine
  • Neuropathology

Background:

  • Sports-related concussion and chronic traumatic encephalopathy (CTE) have gained significant public and scientific attention.
  • CTE was initially described in boxers with a history of head trauma and shares some neuropathological similarities with Alzheimer's disease, notably tau protein deposition.
  • The condition is characterized by cognitive, mood, behavioral, and motor skill impairments, often manifesting after a latency period following repeated head impacts.

Purpose of the Study:

  • To summarize the current understanding of sports-related concussion and chronic traumatic encephalopathy (CTE).
  • To highlight the neuropathological characteristics and suspected pathophysiology of CTE.
  • To emphasize the critical need for early identification and prevention strategies.

Main Methods:

  • Review of historical descriptions of CTE, starting from Martland's 1928 report on boxers.
  • Analysis of clinical and histopathological findings in professional athletes, including former National Football League (NFL) players.
  • Comparison of CTE neuropathology with Alzheimer's disease, focusing on protein deposition patterns (tau vs. amyloid).

Main Results:

  • CTE is associated with a history of repeated concussive and subconcussive blows to the head.
  • Histopathological findings show a predominance of tau protein deposition, distinguishing it from Alzheimer's disease.
  • A significant lag period exists between head trauma and the onset of CTE symptoms.

Conclusions:

  • The pathophysiology of CTE remains incompletely understood, with speculative roles for excitotoxic amino acids and microglial activation.
  • Reducing repeated head impacts is crucial for the prevention of CTE.
  • Further research is essential for early identification and effective management of this neurodegenerative condition.
