- Subdural Hematoma ()
A subdural hematoma forms because of an accumulation of blood under the dura mater, one of the protective layers to the brain tissue under the calvarium. The understanding of subdural hematoma relies on the knowledge of neuroanatomical sheets covering the brain. The brain is the central repository of delicate neural tissue. This network of neurons […]
- Subarachnoid Hemorrhage ()
Overall, about 20% of strokes are hemorrhagic, with SAH and Intracerebral hemorrhage (ICH) each accounting for 10%. Subarachnoid space is described as a space between the arachnoid membrane and the pia mater. It consists of the cerebrospinal fluid and the blood vessels that supply different areas of the brain. A subarachnoid hemorrhage (SAH) is defined […]
- Intracerebral Hemorrhage ()
Intracerebral hemorrhage (ICH), a subtype of stroke, is a devastating condition whereby a hematoma is formed within the brain parenchyma with or without blood extension into the ventricles. Non-traumatic ICH comprises 10-15% of all strokes and is associated with high morbidity and mortality. ICH risk factors include chronic hypertension, amyloid angiopathy, anticoagulation (medication), and vascular […]
- Battle’s Sign ()
Battle Sign (also called Battle’s Sign) is defined as bruising over the mastoid process. It is retroauricular or mastoid ecchymosis that is typically the result of head trauma. Battle sign derives its name from Dr. William Henry Battle who initially described the sign in the late 1800s. He was an English surgeon who initially described […]
- Assessment & Management of Patient’s With Spinal Cord Injuries ()
The scene size up provides the first clue of a spinal cord injury. The mechanism of injury will lead the medics to provide manual stabilization of the cervical spine during the primary survey. Initial management of the patient is always guided by the primary survey. Manually stabilizing the patient’s cervical spine is the third priority […]
- Spinal Cord Injuries ()
Introduction Spinal cord injury (SCI) is a serious medical condition, which often results in severe morbidity and permanent disability. It occurs when the axons of nerves running through the spinal cord are disrupted, leading to loss of motor and sensory function below the level of injury. Injury is usually the result of major trauma, and […]
- Skull Fractures ()
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma. If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to […]
- Protective Layers Of The Brain ()
The central nervous system (CNS) is crucial to the operation of the body and any compromise of function in the brain and spinal cord can lead to severe difficulties. The brain is protected by multiple structures. First, the bones of the skull enclose and house the brain. Underneath the skeletal structures, the brain is protected […]
- Anatomy Of The Brain ()
The brain controls many important body functions, such as emotions, vision, thought, speech, and movement. The spinal cord connects the brain to nerves in most parts of the body. This allows the brain to send messages throughout the body. The network of the brain and spinal cord is called the central nervous system (CNS). Brain Anatomy […]
- How To Determine If A Person Experienced A Head Injury Without Actually Asking them ()
Level of Consciousness Medical illness, traumatic brain injury, alcohol intoxication, drugs, and poisonings may all lead to aberrations in a patient’s neurological and physiological status in ways that cause an abnormal level of consciousness. AVPU is a straightforward scale that is useful to rapidly grade a patient’s gross level of consciousness, responsiveness, or mental status. It comes into […]
