Description:

Headache caused by non-traumatic intracranial haemorrhage and persisting for more than 3 months after the haemorrhage has stabilized.

Diagnostic criteria:
  1. Headache previously diagnosed as 6.2.1 Acute headache attributed to non-traumatic intracerebral haemorrhage, 6.2.2 Acute headache attributed to non-traumatic subarachnoid haemorrhage or 6.2.3 Acute headache attributed to non-traumatic acute subdural haemorrhage and fulfilling criterion C

  4. Not better accounted for by another ICHD-3 diagnosis.
Comments:

A few studies have documented headaches meeting the criteria for 6.2.4 Persistent headache attributed to past non-traumatic intracranial haemorrhage. Research is needed to identify risk factors for such persistent headache; previous history of 1. Migraine may play a role, as may anxiety/depression.

Codable subforms are 6.2.4.1 Persistent headache attributed to past non-traumatic intracerebral haemorrhage, 6.2.4.2 Persistent headache attributed to past non-traumatic subarachnoid haemorrhage and 6.2.4.3 Persistent headache attributed to past non-traumatic acute subdural haemorrhage.
