CEREBRAL VASOSPASM Meaning and
Definition
-
Cerebral vasospasm is a medical condition characterized by the narrowing or constriction of the blood vessels within the brain. Specifically, it refers to the spasm or tightening of the smooth muscles that line the cerebral arteries, which are responsible for supplying necessary oxygen and nutrients to the brain tissue.
This condition typically arises as a complication following a brain hemorrhage, such as a ruptured brain aneurysm or a traumatic head injury. The accumulation of blood in the brain can trigger an inflammatory response, leading to the release of certain chemicals that constrict the blood vessels. As a result, the blood flow to the affected area is significantly reduced, depriving the brain of vital oxygen and nutrients.
Cerebral vasospasm can have severe consequences and pose a significant threat to brain function. It can lead to cerebral ischemia, a condition characterized by inadequate blood supply to the brain, and subsequent ischemic stroke if left untreated. Common symptoms of cerebral vasospasm include severe headaches, neurological deficits, confusion, slurred speech, and even loss of consciousness.
Diagnosis of cerebral vasospasm typically involves medical imaging techniques, such as computed tomography angiography (CTA) or magnetic resonance angiography (MRA), which can provide visualization of the constricted blood vessels. Treatment options may include medications to control blood pressure, alleviate symptoms, and prevent further complications. In more severe cases, surgical procedures like cerebral angioplasty or endovascular therapy may be necessary to restore blood flow and alleviate the vasospasm.

Etymology of CEREBRAL VASOSPASM
The word "cerebral" originates from the Latin word "cerebrum", which means "brain". It is derived from the Proto-Indo-European root *ker- or *keres, meaning "to grow".
The term "vasospasm" is composed of two parts: "vaso-" and "-spasm". "Vaso-" refers to blood vessels and is derived from the Latin word "vas", meaning "vessel". "-Spasm" comes from the Greek word "spasmos", which means "convulsion" or "contraction".
Therefore, the term "cerebral vasospasm" refers to the narrowing or spasm of blood vessels in the brain.
