Intraventricular hemorrhageIntraventricular 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.
Subarachnoid hemorrhageBleeding into the brain's subarachnoid spaceMedical conditionSubarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space—the area between the arachnoid membrane and the pia mater surrounding the brain. Symptoms may include a severe headache of rapid onset, vomiting, decreased level of consciousness, fever, weakness, numbness, and sometimes seizures. Neck stiffness or neck pain are also relatively common.
Intracerebral hemorrhageIntracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e., the parenchyma), into its ventricles, or both. An ICH is a type of bleeding within the skull and a kind of stroke (ischemic stroke being the other).
StrokeDeath of a region of brain cells due to poor blood flowMedical conditionA stroke, also referred to as a cerebrovascular accident, is a medical condition in which blood flow to a part of the brain is reduced or blocked causing cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly.
Intracranial pressureIntracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury (mmHg) and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH2O, which is a common scale used in lumbar punctures.
ParenchymaParenchyma () is the bulk of functional substance in an animal organ such as the brain or lungs, or a structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf.
EdemaEdema (American English) or oedema (Commonwealth English), also known as dropsy, hydropsy, fluid retention, or simply swelling, is the buildup of fluid in a bodily tissue. Most commonly, the legs or arms are affected. Besides observable swelling, symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. Other symptoms depend on the underlying cause.
DeathDeath is the end of an organism's life. It is the irreversible cessation of biological functions that sustain a living organism. Death is inevitable for all living things, as nature's tendency to disorder will cause all living systems to degrade and fail through various causes. The identification of the moment of death presents certain difficulties. A person may experience clinical death that is reversible, resulting in some cases in a near-death experience.
Medical emergencyA medical emergency is an acuteinjury or illness that poses an immediate risk to a person's life or long-term health, sometimes referred to as a situation risking "life or limb". These emergencies may require assistance from another, qualified person, as some of these emergencies, such as cardiovascular (heart), respiratory, and gastrointestinal cannot be dealt with by the victim themselves.
Human brainCentral organ of the human nervous systemThe human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system.
