Nimodipine, sold under the brand name Nimotop among others, is a calcium channel blocker used in preventing vasospasm secondary to subarachnoid hemorrhage (a form of cerebral hemorrhage). It was originally developed within the calcium channel blocker class as it was used for the treatment of high blood pressure, but is not used for this indication.
Trauma is the most common cause of intracranial hemorrhage. It can cause epidural hemorrhage, subdural hemorrhage, and subarachnoid hemorrhage. Other condition such as hemorrhagic parenchymal contusion and cerebral microhemorrhages can also be caused by trauma. [3]
A non-contrast Cat Scan of the head should be utilized as the primary imaging modality during initial diagnosis. Prognosis and treatment are determined by location and size of the hemorrhage. [5] Subarachnoid hemorrhage is most commonly caused by the rupture of an aneurysm, usually at the base of the brain.
A subarachnoid hemorrhage brought on by a ruptured aneurysm, or less frequently, other forms of brain hemorrhages (such intracerebral or subdural hemorrhages), is usually the origin of the abrupt increase in intracranial pressure that frequently precedes the onset of Turner's syndrome.
Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or major disability than ischemic stroke or subarachnoid hemorrhage, and therefore constitutes an immediate medical emergency.
Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke.
On the other hand, trauma, which generally originates from terminal vascular network, is a common cause of spinal cord hemorrhage for all four subtypes, namely haematomyelia, subarachnoid hemorrhage, subdural hemorrhage and epidural hemorrhage. [9] There is a correlation between anticoagulating drugs and hemorrhagic stroke. [9]
