Final answer:
Migraines tend to be unilateral, although they can be bilateral in some cases.
Step-by-step explanation:
Migraines are typically experienced on one side of the head, although they can be bilateral in some cases. A unilateral migraine refers to a headache that affects only one side of the head. This is often accompanied by other symptoms such as nausea, sensitivity to light and sound, and visual disturbances.
For example, a person may experience a migraine on the right side of their head, characterized by a throbbing pain, while the left side remains unaffected.
