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...

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...

Summary
This summary is machine-generated.

Intracranial self-stabbing, a form of self-harm, is often linked to psychotic illness but not always suicidal. This under-recognized behavior requires further clinical attention.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Forensic Medicine

Background:

  • Limited understanding of the psychiatric profile of individuals engaging in intracranial self-stabbing.
  • Uncertainty regarding the suicidal intent and association with psychotic symptoms in these cases.

Observation:

  • A review of cases in New South Wales (NSW) and a systematic search of published literature identified 52 instances of intracranial self-stabbing.
  • Analysis revealed that 55% of cases with available diagnoses were associated with psychotic illness.

Findings:

  • Intracranial self-stabbing is not exclusively a suicide attempt and typically does not result in fatality.
  • The behavior is associated with psychotic illness in a majority of diagnosed cases.

Implications:

  • Intracranial self-stabbing is an under-recognized manifestation of self-harm.
  • Highlights the need for increased awareness and specialized psychiatric assessment for individuals exhibiting this behavior.
