CISTERNOGRAM | SHOWS CSF FLOW | |
What is triple H therapy? | HYPERTENSION, HYPERVOLEMIA, HEMODILUTION | To reduce the potention for cerebral artery vasospasm. |
What is Cushing triad or reflex? | Pt. present with an increase in systolic BP, a drecrease in diastolic BP (WIDENING PULSE PRESSURE)and bradycardia. | It is a late sign of increase intracranial pressure. |
What range should cerebral perfusion pressure be maintained for autoregulation? | 50 - 150 mmHg | |
What is Broca's aphasia? | It is the inability to express oneself (Motor or expressive aphasia) | Caused by a problem in the Broca area of the frontal lobe. |
What is Wernicke's aphasia? | Sensory or receptive aphasia | Caused by problem in the Wernicke's area of the temporal lobe. |
What is dysprosody? | The lack of inflection during speech | |
Where is the Broca area located? | It is in the frontal lobe | The frontal lobe controls voluntary motor functions. |
Where is the Wernicke's area located? | It is in the temporal lobe. | The temporal lobe controls hearing |
SUBDURAL HEMATOMA | VENOUS BLEED | |
EPIDURAL HEMATOMA | ARTERIAL BLEED | |
What are A waves in ICP waveforms | Spontaneous,Rapid increases in pressure between 50 - 200 mm Hg. That last 5 minutes or more. | A waves can cause cerebral ischemia. They are the most clinical significant wave form. Immediate intervention is necessary. |

CEREBRUM | governs all sensory and motor and learning; analyzes, associates, integrates, and stores information. | |
FRONTAL LOBE | motor function; motor speech area; controls morals, values, emotions, and judgment | |
PARIETAL LOBE | integrates general sensation; governs discrimination; interprets pain, touch, temperature, and pressure. | |
What are the four lobes of the CEREBRAL CORTEX | FRONTAL LOBE, PARIETAL LOBE, TEMPORAL LOBE, OCCIPITAL LOBE | |
TEMPORAL LOBE | Auditory center; sensory speech center | |

Central cord syndrome (CCS) | It is marked by a disproportionately greater impairment of motor function in the upper extremities than in the lower ones, as well as by bladder dysfunction and a variable amount of sensory loss below the level of injury. | Central cord syndrome (CCS) most often occurs after a hyperextension injury in an individual with long-standing cervical spondylosis. |
Brown Sequard Syndrome | Ipsilateral motor loss Contralateral loss of pain and temperature | HEMISECTION OF CORD CUT |
What is battle sign? | bruising of the mastoid | Indicative of Basal skull fracture |
