Online learning module based around an original peer-reviewed article focusing on the diagnosis of subarachnoid haemorrhage (SAH), especially low volume SAH that may not present with typical symptoms, but requires urgent investigationRelevance to General Practice
- Headache, a common presentation in primary care, can occasionally be a symptom of a neurological condition requiring urgent neurosurgical treatment.
- While patients presenting with sudden severe ‘thunderclap’ headache, with or without associated indicative symptoms clearly need immediate investigation for probable subarachnoid haemorrhage (SAH), patients with atypical or mild symptoms of SAH are more difficult to diagnose.
- Patients with less typical symptoms may have a low volume SAH not detectable on CT but warranting further investigations. These investigations are not without risk so significant decisions must be made.
- The critical issue is the diagnosis of the haemorrhage itself as a missed haemorrhage can have devastating effects for the patient.
