Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

18
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...

Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

967
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

23
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component...

Increased Intracranial Pressure ll: Pathophysiology

19
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...

Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

16
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

587
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Area of Science:

  • Neurology
  • Neuroscience
  • Headache Medicine

Background:

  • Post-traumatic headache (PTH) is the most frequent secondary headache disorder.
  • PTH is a significant cause of morbidity after traumatic brain injury (TBI).
  • Its pathophysiology remains unclear, with debated roles for psychological and medico-legal factors.

Purpose of the Study:

  • To review the clinical aspects of post-traumatic headache (PTH).
  • To discuss the diagnostic criteria for PTH.
  • To highlight unresolved issues in PTH classification and understanding.

Main Methods:

  • Literature review focusing on clinical presentations of PTH.
  • Analysis of diagnostic criteria for PTH.
  • Discussion of controversies and unsolved issues in PTH.

Main Results:

  • PTH can be an isolated symptom or part of post-concussive syndrome.
  • PTH may represent an exacerbation of pre-existing headaches rather than a new onset.
  • The International Classification of Headache Disorders has attempted PTH classification, but further clarification is needed.

Conclusions:

  • Post-traumatic headache (PTH) diagnosis and management remain complex.
  • Further research is required to elucidate PTH pathophysiology and refine diagnostic criteria.
  • Understanding PTH clinical features is crucial for effective patient care and research.
