==Overview==
==Overview==
[[Intraparenchymal hemorrhage]] is one of the common causes of [[stroke]]. Although less prevalent than [[ischemia]], [[intraparenchymal hemorrhage]] has the highest [[mortality rate]] among all the causes of [[stroke]]. It is associated with multiple risk factors, with [[hypertension]] being the most common among them. It occurs more commonly in the older population. Diagnosis is made using [[Ct-scan]] or [[MRI brain]]. Owing to its poor prognosis, early diagnosis and management are of paradigm importance.

Although less prevalent than [[ischemia]], [[intraparenchymal hemorrhage]] has the highest [[mortality rate]] among all the causes of [[stroke]]. It is associated with multiple risk factors, with [[hypertension]] being the most common among them. It can be classified into primary or secondary type depending upon the underlying etiology.

Overview

Intraparenchymal hemorrhage is one of the common causes of stroke. Although less prevalent than ischemia, intraparenchymal hemorrhage has the highest mortality rate among all the causes of stroke. It is associated with multiple risk factors, with hypertension being the most common among them. It can be classified into primary or secondary type depending upon the underlying etiology. Intraparenchymal hemorrhage occurs more commonly in the older population. Diagnosis is made using Ct-scan or MRI brain. Owing to its poor prognosis, early diagnosis and management are of paradigm importance.

Differentiating intraparenchymal hemorrhage from other Diseases

  • Intraparenchymal hemorrhage must be differentiated from ischemic stroke. But it is difficult to differentiate between the 2 based on clinical features. Therefore, neuroimaging should always be used to confirm the diagnosis.
