• severe
  • The jarring of the brain maybe so slight that it only causes temporary dizziness and headache, sometimes it maybe severe to cause a complete loss of consciousness for a period of time. (graduateway.com)
  • Tumors
  • CT scanning of the head is also used in CT-guided stereotactic surgery and radiosurgery for treatment of intracranial tumors, arteriovenous malformations and other surgically treatable conditions using a device known as the N-localizer. (wikipedia.org)
  • mannitol
  • 11,12 Other agents include rheological fluids such as hypertonic saline (HS), which has been shown to have similar effects to mannitol in various intracranial pathologies, but the duration of its action is longer. (ahajournals.org)
  • Respiratory
  • In response to rising intracranial pressure (ICP), respiratory cycles change in regularity and rate. (wikipedia.org)
  • The anaerobes often isolated from brain abscesses complicating respiratory and dental infections are anaerobic Gram-negative bacilli (AGNB, including Prevotella, Porphyromonas, Bacteroides), Fusobacterium and Peptostreptococcus spp. (wikipedia.org)
  • skull
  • Open injuries involve penetration of the scalp and skull (and usually the meninges and underlying brain tissue). (merckmanuals.com)
  • The following outline is provided as an overview of and topical guide to the human brain: Human brain - central organ of the nervous system located in the head of a human being, protected by the skull. (wikipedia.org)
  • Peripheral nervous system - consists of nerves outside the brain and spinal cord, where they are not protected by the human vertebral column, skull and the protective blood-brain barrier. (wikipedia.org)
  • The brain resides within the skull, a rigid closed compartment. (graduateway.com)
  • As a result any bleeding or swelling within the skull increases the volume of its contents and thus causing increased intracranial pressure. (graduateway.com)
  • Increased pressure to the brain within the skulls causes a downward or lateral displacement of the brain within the structure of the skull. (graduateway.com)
  • It is caused by increased pressure inside the skull. (wikipedia.org)
  • structures
  • Increased pressure above the tentorium may also involve other midbrain structures. (wikipedia.org)
  • Identifying the location of these structures on a damaged brains compared to an unaffected brain is another way of categorizing the severity of the midline shift. (wikipedia.org)
  • outcomes
  • Targeted temperature management (TTM) previously known as therapeutic hypothermia or protective hypothermia is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain. (wikipedia.org)
  • thrombosis
  • A CT scan of the brain demonstrated a comminuted-depressed fracture of the parietal bone in the midline with a rupture of the superior sagittal sinus (SSS) and secondary thrombosis (figure 1). (bmj.com)
  • Reduction
  • The Cushing reflex classically presents as an increase in systolic and pulse pressure, reduction of the heart rate (bradycardia), and irregular respiration. (wikipedia.org)
  • symptoms
  • These symptoms can be indicative of insufficient blood flow to the brain (ischemia) as well as compression of arterioles. (wikipedia.org)
  • Cushing's
  • Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia. (wikipedia.org)
  • decrease
  • This decreased flow often causes a reflexive HTN (increase in blood pressure) despite the actual decrease in intravascular volume. (wikipedia.org)
  • trials
  • These recommendations were largely based on two trials from 2002 which showed improved survival and brain function when cooled to 32-34 °C (90-93 °F) after cardiac arrest. (wikipedia.org)
  • chronic
  • The origin of brain abscess is generally an adjacent chronic ear, mastoid, or sinus infection oropharynx, teeth or lungs. (wikipedia.org)
  • tissue plasminog
  • It works by stimulating secondary fibrinolysis by plasmin through infusion of analogs of tissue plasminogen activator (tPA), the protein that normally activates plasmin. (wikipedia.org)
  • stem
  • Human brain List of regions in the human brain Lobes of the brain Brain Basal ganglia Brain stem including Medulla oblongata, midbrain, pons Cerebellum Cerebral cortex Hypothalamus Limbic including amygdala Neuroanatomy Note - in conducting brain research, information "where the other end connects" is critical to understanding neural connections, and ultimately how the brain functions. (wikipedia.org)
  • The sign is considered ominous because it is commonly associated with a distortion of the brain stem that can cause serious dysfunction evidenced by abnormal posturing and failure of the pupils to constrict in response to light. (wikipedia.org)
