Neurological deterioration affects approximately one-third of patients with primary intracerebral hemorrhage (ICH) and increases the risk of death and dependency. However, the risk factors of early neurological deterioration (END), such as biochemical parameters, neuroimaging, and systemic complications, are not well documented in primary ICH, and the effective predictors of END is unknown.~This multicenter observational study aims to seek out the risk factors of END in patients with primary ICH and to investigate the association between END and outcome.
