What condition is likely indicated by the 26-year-old pregnant female's sudden severe headache and unresponsiveness?

The scenario describes a 26-year-old pregnant female experiencing a sudden severe headache and unresponsiveness, which are critical symptoms that warrant immediate medical evaluation. The presentation strongly suggests the possibility of an intracranial hemorrhage.

Intracranial hemorrhage can occur due to various factors, including trauma, vascular malformations, or as a complication during pregnancy (e.g., ruptured aneurysm or venous sinus thrombosis). The sudden onset of a severe headache, often described as a "thunderclap" headache, along with altered consciousness (unresponsiveness), indicates a serious neurological event. These symptoms typically require urgent imaging studies such as a CT scan to confirm the diagnosis and assess the extent of bleeding.

In contrast, minor migraine headaches generally do not lead to unresponsiveness and are often associated with specific triggers or a history of similar headaches. Sinusitis typically presents with facial pain and pressure but does not cause severe headaches or loss of consciousness. Preeclampsia may lead to headaches and other symptoms like high blood pressure but would also commonly include other signs such as edema and protein in the urine, and would not typically account for sudden unresponsiveness.

Given the acute and severe nature of this patient’s symptoms, an
