Characteristics and management of headache among psychiatric outpatients at a Japanese general hospital: A retrospective study with an exploratory CGRP case series.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aim: Headache is one of the most frequent somatic complaints in psychiatric practice and is often attributed to underlying mental disorders. However, primary headache disorders-particularly migraine and tension-type headache (TTH)-commonly coexist with psychiatric conditions. Evidence from psychiatric outpatient settings remains limited. Methods: We conducted a retrospective chart review of all psychiatric outpatients who visited our 600-bed regional general hospital between April 1, 2023, and March 31, 2024. Among 2525 patients, we identified 360 individuals with headache-related insurance diagnoses and extracted data on headache labels, treating departments, and prescribed medications. For calcitonin gene-related peptide (CGRP)-targeted monoclonal antibodies, we extended the observation period to March 31, 2025, to describe an exploratory case series including additional prescriptions. Results: Of 2525 psychiatric outpatients, 360 (14.3%) carried a headache-related insurance diagnosis. The most frequent labels were "headache" (203/360, 56.4%), migraine (92/360, 25.6%), and TTH (46/360, 12.8%); cluster headache and medication-overuse headache (MOH) were each recorded in 1/360 (0.3%). Headache care was most often delivered within psychiatry (153/360, 42.5%), followed by neurology (42/360, 11.7%), neurosurgery (40/360, 11.1%), general internal medicine (28/360, 7.8%), and rheumatology/collagen-vascular disease (15/360, 4.2%). Commonly documented agents included nonsteroidal anti-inflammatory drug (NSAIDs) (40/360, 11.1%), acetaminophen (38/360, 10.6%), triptans (23/360, 6.4%), Japanese Kampo formulas (16/360, 4.4%), and CGRP monoclonal antibodies (6/360, 1.7%). At the agent level, acetaminophen ( Conclusion: In a psychiatric outpatient cohort, primary headaches were common and frequently managed within psychiatry. CGRP-targeted therapy yielded headache relief even under psychiatric comorbidity, while psychiatric symptoms did not uniformly improve, underscoring the need for parallel mental-health interventions alongside headache-specific care. Strengthening cross-specialty pathways and early headache evaluation within psychiatry are warranted.
