Diagnostic Approach to Paresthesia of Head, Face, and Back with Lightheadedness

Primary Diagnostic Considerations

The International Classification of Headache Disorders recognizes sensory aura presenting as "pins and needles" as a positive aura symptom, which typically spreads gradually over ≥5 minutes, lasts 5-60 minutes, and may be unilateral 1
Migraine-associated dizziness accounts for 14% of adult vertigo cases and can present without headache, making it critical to consider even without classic migraine symptoms 2
Vestibular symptoms of moderate to severe intensity lasting 5 minutes to 72 hours, combined with migraine features, define vestibular migraine 1
Lightheadedness and spatial disorientation are characteristic vestibular symptoms 1

Isolated transient vertigo and paresthesias may precede vertebrobasilar stroke by weeks or months 3
The presence of additional neurological signs (dysarthria, dysmetria, dysphagia, sensory/motor loss) suggests central causes like stroke 4
Gaze-evoked nystagmus that does not fatigue distinguishes central from peripheral causes 3

MRI brain with and without contrast is the study of choice when CNS pathology is suspected 9
Neurological symptoms (dysarthria, dysmetria, dysphagia, sensory/motor loss) mandate urgent imaging 4
The diagnostic yield of imaging in nonspecific dizziness without vertigo, ataxia, or neurologic deficits is extremely low (<1% for CT, 4% for MRI) 2

Migraine prophylaxis and trigger avoidance are recommended for migraine with aura or vestibular migraine 2
Consider triptans for acute episodes if headache component present 1
Manual therapy combined with vestibular rehabilitation exercises is most effective for cervicogenic dizziness 2
Cognitive behavioral therapy and appropriate anxiolytic management are recommended for anxiety/panic disorder 2
Urgent vascular neurology consultation for stroke prevention strategies is necessary for vertebrobasilar insufficiency 3
