What is Headache Attributed to Other Non-Vascular Intracranial Disorder? (Definition/Background Information)

Headache Attributed to Other Non-Vascular Intracranial Disorder is a headache disorder that occurs secondary to any non-vascular intracranial disorder, except for the following (since described elsewhere):

• Conditions causing increased cerebrospinal fluid pressure such as:
  • Idiopathic intracranial hypertension
  • Intracranial hypertension from metabolic, toxic or hormonal cause
  • Intracranial hypertension from chromosomal disorder
  • Intracranial hypertension from hydrocephalus
• Conditions causing low cerebrospinal fluid pressure such as:
  • Post-dural puncture procedure
  • Cerebrospinal fluid fistula
  • Spontaneous intracranial hypotension
• Non-infectious inflammatory intracranial diseases such as:
  • Neurosarcoidosis
  • Aseptic (non-infectious) meningitis
  • Lymphocytic hypophysitis
  • HaNDL syndrome
• Intracranial neoplasia, including:
  • Colloid cyst of the third ventricle
  • Carcinomatous meningitis
  • Hypothalamic or pituitary hypersecretion or hyposecretion
  • Intrathecal injection
• Epileptic seizures
• Chiari malformation type I

The headache that develops is known to improve and regress on undertaking suitable management of the underlying non-vascular intracranial disorder. Similarly, a progression of the disorder, in the absence of adequate treatment, can worsen the headache.

The criteria for diagnosis of Headache Attributed to Other Non-Vascular Intracranial Disorder as outlined by the International Headache Society (IHS) is given below:

• A non-vascular intracranial disorder known to be able to cause headache, other than those described above, has been demonstrated
• Any headache fulfilling the criterion below

Evidence of causation demonstrated by at least two of the following:

• Headache has developed in temporal relation to the onset of the non-vascular intracranial disorder
• Either or both of the following
  • Headache has developed or significantly worsened in parallel with worsening of the non-vascular intracranial disorder
  • Headache has significantly improved in parallel with improvement of the non-vascular intracranial disorder
• Headache has characteristics typical for the non-vascular intracranial disorder
• Other evidence exists of causation

Not better accounted for by another ICHD-3 diagnosis.
