Abnormal sleep latency and concentration-related impairment in function were more frequent in patients with chronic migraine than those with episodic migraine, a new study found. Researchers investigated the coexistence of symptoms associated with trigeminal pathways in chronic and episodic migraine and their effects on quality of life. The presence of cranial autonomic symptoms, vertigo/dizziness, cutaneous allodynia, concentration-related impairment in function, and abnormal sleep latency were sought in patients with questionnaires, and comparisons were made between episodic and chronic migraine groups. Among the details:
- 1,080 patients with migraine were included.
- Abnormal sleep latency and concentration-related impairment in function were more frequent in patients with chronic migraine vs those with the episodic form.
- These 2 symptoms were significantly more frequent in separate patient groups with cranial autonomic symptoms, vertigo/dizziness, and cutaneous allodynia than in patients without.
