3. High sensitivity to light and sound
There are a series of neurologic findings associated with migraine pain, and the most common is high sensitivity to light and/or sound. They are clinically named photophobia and phonophobia, and usually appear when there’s an insult to the meningeal linings of the brain, which is why they are listed as symptoms of meningism or meningeal involvement.
This symptom is very important in the diagnosis of migraines, and patients must either have nausea and vomiting, high sensitivity to light and/or sound, or both symptoms at the same time. Other less common neurologic findings that some patients may report in cases of migraines are paralysis or weakness in one side of the body, vertigo, difficulty to speak or coordinate speech, and other symptoms we will describe when talking about migraine auras.
