What are the sequelae of subarachnoid hemorrhage

Sequelae such as hydrocephalus, headache, and head discomfort can occur after subarachnoid hemorrhage.
The blood clots in the subarachnoid space block the flow channels of cerebrospinal fluid, resulting in hydrocephalus due to the retention of cerebrospinal fluid. After subarachnoid hemorrhage, some of the cerebral blood vessels spasm, which in turn causes headache and head discomfort. These sequelae may be cured with treatment.
If subarachnoid hemorrhage is followed by complications such as cerebral herniation, it may cause a series of sequelae such as hemiplegia.
