Emergency Department Evaluation is Urgently Indicated
A 79-year-old patient with severe headache for 3 days and dizziness should go to the emergency room immediately for urgent evaluation. This presentation contains multiple red flags that warrant immediate medical assessment, including new-onset severe headache in an older adult, prolonged duration, and associated neurological symptoms.
Critical Red Flags Present
This patient exhibits several concerning features that mandate urgent evaluation:
- New headache in elderly patient (>50 years) - This is a well-established red flag requiring immediate neuroimaging consideration 1, 2
- Severe, persistent headache lasting 3 days - Prolonged duration with severity suggests potential serious underlying pathology 2
- Associated dizziness - Neurological symptoms accompanying headache increase concern for cerebrovascular events, including stroke or cerebral venous thrombosis 1, 3
- Age 79 years - Older adults presenting with these symptoms have higher rates of serious pathology and require more intensive evaluation 4, 5
Immediate Emergency Department Evaluation Required
Initial Assessment Priorities
The ED evaluation should focus on excluding life-threatening causes:
- Neuroimaging with MRI (preferred) or CT - Brain MRI with and without contrast is recommended to evaluate for structural abnormalities, signs of increased intracranial pressure, stroke, hemorrhage, and secondary causes of headache 3, 2
- MR venography (MRV) - Should be considered to rule out cerebral venous thrombosis, which can present with persistent headache and dizziness 1, 3
- Vital signs with blood pressure monitoring - Severe hypertension can cause headache and dizziness, and hypertensive emergency (BP >180/110 mmHg) requires immediate intervention 3, 6
- Complete neurological examination - Focus on mental status, cranial nerve function, motor/sensory deficits, and fundoscopic examination for papilledema 2
Laboratory Testing in ED
Essential blood work includes:
- ESR and CRP - To evaluate for giant cell arteritis (temporal arteritis), which is critical in patients over 50 with new headache, especially if scalp tenderness or jaw claudication present 1, 2
- Complete blood count and metabolic panel - To assess for infection, anemia, electrolyte abnormalities, and renal function 3
- Glucose and hemoglobin A1c - If vasculopathic etiology suspected 1, 2
Specific Concerns in This Age Group
Cerebrovascular Events
Older adults with headache and dizziness are at increased risk for:
- Stroke or transient ischemic attack - Cerebral hemorrhage, subarachnoid hemorrhage, and ischemic stroke can present with severe headache and dizziness 7
- Cerebral venous thrombosis - Can present with persistent headache and neurological symptoms, requiring prompt diagnosis 1, 3
Giant Cell Arteritis
This is a critical consideration in patients over 50:
- Temporal artery evaluation - Check for scalp tenderness, jaw claudication, or temporal artery abnormalities 1, 2
- Immediate treatment if suspected - High-dose corticosteroids should be initiated immediately if giant cell arteritis suspected, even before biopsy confirmation 2
Increased Intracranial Pressure
Signs requiring immediate attention include:
- Papilledema on fundoscopic exam - Indicates elevated intracranial pressure 1
- Progressive worsening - Headache that progressively worsens over days suggests space-occupying lesion or other serious pathology 1, 2
Why Outpatient Management is Inappropriate
Do not attempt outpatient management or delay ED evaluation for the following reasons:
- Older adults (especially >75 years) presenting to ED with neurological symptoms have high rates of appropriate urgent/emergent conditions requiring immediate intervention 4, 5
- The combination of severe headache, dizziness, and advanced age represents high-risk features that cannot be adequately evaluated in outpatient settings 2
- Time-sensitive conditions like stroke, cerebral venous thrombosis, and giant cell arteritis require immediate diagnosis and treatment to prevent permanent neurological damage or death 1, 2, 7
- Older adults have increased complexity and higher hospitalization rates when presenting with these symptoms 5
Common Pitfalls to Avoid
- Do not assume this is migraine - While migraine can occur in older adults, new-onset headache after age 50 requires exclusion of secondary causes first 1, 2
- Do not prescribe triptans without evaluation - Triptans are contraindicated in patients with cerebrovascular disease, uncontrolled hypertension, and multiple cardiovascular risk factors common in this age group 1, 7
- Do not delay for outpatient imaging - Urgent neuroimaging in ED setting is required, not scheduled outpatient studies 3, 2
