Recent onset transient or episodic headaches with concerning features: risk prediction, pre-test probability, and imaging selection
Differentiating patients with headache to identify serious and life-threatening brain bleeds
Episodic headaches are a widely experienced complaint. While the majority are due to benign processes, some headaches can herald serious and life‐threatening diseases. One such cause is a type of brain bleed known as a subarachnoid haemorrhage that can present initially as a ‘sentinel bleed’. This research aims to investigate the proportion of patients presenting with transient headache and concerning features that are later confirmed to have these serious brain bleeds. This information will help to identify these patients so that they receive the appropriate scans and treatment in a timely fashion that reduces potential serious illness.
