Neurology in Primary Care

Neurological presentations account for 10–15% of all GP consultations. Most are benign and manageable in primary care — but the stakes for missing a serious diagnosis are high. Headache, dizziness, and weakness are among the most common and most anxiety-provoking presentations. Know the red flags, act fast on strokes, and refer strategically.
