Approach to Approach to Intracranialemergency Intracranialemergency
Neurologic symptoms
Weakness, difficulty speaking, concentrating, swallowing, or thinking, imbalance, sensory changes, visual problems, and headache.
Altered mental status
Dizziness and vertigo
HeadacheHeadache
KEY CONCEPTS
Headache is a common presenting complaint in the emergency department. The emergency physician must distinguish between benign primary headache disorders and the more serious and potentially life-threatening secondary causes of headache.
The majority of patients do not have abnormal neurologic findings; therefore, the key to a successful diagnosis is a thorough and systematic history.
Patients with the following headache presentations are at risk for serious underlying disease:
• sudden explosive headache; • first or worst headache; • new-onset headache after age 50; • headache associated with papilledema, alteration
in or loss of consciousness, or focal neurologic symptoms;
• headache after head trauma; • subacute headache with increasing frequency or
severity; • headache associated with fever, cancer, or
immunosuppression; • headache triggered by exertion, sexual activity, or
Valsalva maneuver.
The need for diagnostic studies is dictated by the suspected secondary cause of headache
Historical danger signs in patients with headache
SeizuresSeizures
Stroke
Stroke means “ rapidly developed clinical signs of focal (global)
disturbance of cerebral function lasting more than 24 hours or
leading to death, with no appearance cause other than a
vascular origin.”
KEY CONCEPTS
• Patients presenting with the signs and symptoms of an acute ischemic stroke within 3 hours of symptom onset should be evaluated for thrombolytic therapy within the following recommended target time frames: Door to physician: 10 minutes Door to CT completion: 25 minutes Door to CT reading: 45 minutes Door to drug treatment: 60 minutes
• Carotid Doppler, MRA, or CT angiography studies are recommended before discharging a patient with TIA.
• Avoid overaggressive blood pressure management in patients with acute ischemic stroke.
• Accurate time of symptom onset should be documented for all patients with stroke.
• Assessment of gait is essential to rule out posterior circulation stroke in patients presenting with vertigo.
KEY CONCEPTS
• Patients presenting with the signs and symptoms of an acute ischemic stroke within 3 hours of symptom onset should be evaluated for thrombolytic therapy within the following recommended target time frames: Door to physician: 10 minutes Door to CT completion: 25 minutes Door to CT reading: 45 minutes Door to drug treatment: 60 minutes
Figure 99-2 A, CT scan taken 2 hours, 50 minutes after large right middle cerebral artery occlusion. There are subtle, ultra-early ischemic changes, including loss of the gray-white interface (arrows) and subtle evidence of sulcal effacement. B, CT scan of same patient approximately 8 hours after symptom onset shows acute hypodensity (arrows) and more prominent sulcal effacement.

Figure 99-1 The CT slice with the largest area of hemorrhage is identified. The largest diameter of the hemorrhage on this slice is measured in centimeters (A). The largest diameter 90 degrees to A on the same slice is measured (B). C is the approximate number of 10-mm slices on which the intracerebral hemorrhage was seen. The volume of the hemorrhage equals A multiplied by B, multiplied by C, divided by 2 (ABC/2).
