Confabulation due to ACom rupture

  • Differential Diagnosis for Confabulation: Thiamine-deficiency (Wernicke-Korsakoff), cerebrovascular lesions (rupture of anterior communicating artery aneurysm, rostral brainstem, bithalamic, hypothalamic lesions), traumatic brain injury, space occupying lesion – malignancy, hydrocephalus, herpes encephalitis, neurosyphilis, nicotinic acid deficiency, multiple sclerosis, dementia.
  • Modifiable Risk factors for intracranial arterial aneurysms are smoking and hypertension.  Patients with ADPKD have a 12% chance of having intracranial aneurysms.  Other conditions that carry a higher risk of intracranial arterial aneurysms are Ehlers-Danlos, Moyamoya and familial aneurysms.
