Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

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, are a...
Traumatic Brain Injury l: Introduction01:28

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...
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...
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...
Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

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 expands, CSF and venous blood...
Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

Summary
This summary is machine-generated.

Posttraumatic headache (PTH) following concussion and mild traumatic brain injury (mTBI) is common. Despite advances in diagnosis, evidence-based treatments for PTH remain limited, relying on expert opinion.

Area of Science:

  • Neuroscience
  • Traumatology
  • Neurology

Background:

  • Posttraumatic headache (PTH) is a frequent and debilitating outcome of concussion and mild traumatic brain injury (mTBI).
  • Recent epidemiological data indicate underestimation of concussion and mTBI incidence, identifying at-risk populations.
  • Concussion induces metabolic brain dysfunction, increasing vulnerability to secondary injury.

Purpose of the Study:

  • To review recent advancements in the epidemiology, evaluation, and management of concussion, mTBI, and PTH.
  • To highlight current understanding of the pathophysiology and diagnostic approaches for PTH.

Main Methods:

  • Review of current epidemiological studies on concussion and mTBI.
  • Analysis of advanced neuroimaging techniques (MR spectroscopy, diffusion tensor imaging) for detecting acute and subacute abnormalities.
  • Evaluation of existing treatment strategies and guidelines for PTH.

Main Results:

  • Epidemiological studies reveal higher than previously thought incidence of concussion and mTBI.
  • Advanced imaging effectively identifies metabolic brain derangements post-concussion.
  • No randomized, placebo-controlled trials support specific PTH treatments; management relies on expert opinion and primary headache guidelines, predominantly migraine.

Conclusions:

  • Significant progress has been made in understanding concussion, mTBI, and PTH pathophysiology and diagnosis.
  • There is a notable lack of evidence-based treatment guidelines for posttraumatic headache.
  • Further research is needed to develop effective, evidence-based therapeutic interventions for PTH.
