Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a longitudinal, multi-center, prospective study of aneurysmal subarachnoid haemorrhage patients in neurosurgical units in Hong Kong.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators aim to recruit a total of 240 aneurysmal subarachnoid haemorrhage patients. The schedule for neuropsychological and functional assessments will be phased in at the second to third week, the third month, and the twelve months after the initial haemorrhage.
