Diagnosis and treatment of migraine in the patient with depression

Clinical efficacy of escitalopram combined with botulinum toxin A in patients with generalized anxiety disorder and comorbid headache

BACKGROUND

Generalized anxiety disorder (GAD) is a common mental disorder that happens comorbidly with other diseases. Headache is a common anxiety comorbidity. Previous reports have shown that the selection of therapeutic drugs for GAD patients and comorbid headache is challenging. Therefore, our study aimed to investigate the clinical efficacy of escitalopram combined with botulinum toxin A (BoNT/A) in patients with GAD and comorbid headache and seek an alternative treatment strategy for the comorbidity of GAD and headache.

METHODS

A prospective, randomized controlled, double-blind study was performed. The eligible GAD patients with comorbid headache were randomly assigned to the BoNT/A group and the placebo group. All the patients were given oral escitalopram therapy (10-20 mg/day) for the whole duration of the study. The BoNT/A group was given local injections of BoNT/A (50 U per person), whereas the placebo group was given local saline (0.9% NaCl) injections at the beginning and 3 months after the experiments. All participants were followed up for 6 months and relevant information was collected at months 0, 1, 2, 3, and 6. Primary outcomes included the following: (1) the Generalized Anxiety Disorder 7 (GAD-7); (2) the Self-rating Anxiety Scale (SAS); (3) the Hamilton Anxiety Rating Scales (HAMA); (4) days with headache per month; (5) visual analogue scale (VAS).

RESULTS

A total of 101 patients (the sex ratio of female to male: 3.39:1) were finally included. Compared with the placebo group, the BoNT/A group showed a significant decrease in GAD-7 scores, SAS scores, HAMA scores, days with headache per month, and VAS scores at months 1, 2, 3, and 6 of follow-up (all p < 0.05). The average time to complete remission of anxiety symptoms (HAMA< 7 points) in the BoNT/A group was less than the placebo group (2 months vs. 3 months). At the same time, the results of the survival analysis showed a clear beneficial effect of BoNT/A relative to placebo on the time to remission of anxiety (log-rank test, p < 0.001). Mean daily doses of escitalopram at the sixth month in the BoNT/A group was smaller than the placebo group (12.5 mg vs. 16.04 mg, p < 0.001). The number of patients who relapsed (HAMA total score ≥ 14 points) at 6 months of follow-up in the BoNT/A group was less than the placebo group (2.2% vs. 14.9%, p < 0.05). The rates of response (HAMA subtraction rate ≥ 50%) were 93.8% for the BoNT/A group and 75.5% for the placebo group (p < 0.05), and the rates of remission (HAMA < 7 points) were 87.5% for the BoNT/A group and 64.2% for the placebo group (p < 0.01) at the sixth month.

CONCLUSION

The combination of escitalopram with BoNT/A is a significantly effective intervention in improving clinical efficacy and reducing the recurrence in patients with GAD and comorbid headache, and we believe that this approach will be an additional treatment strategy for future treatment of comorbid headache in GAD. Therefore, we recommend that escitalopram combined with BoNT/A should be given as early as possible in GAD patients and comorbid headache.

Effects of acupuncture on mental health of migraine patients: a systematic review and meta-analysis

BACKGROUND

Migraine is a neurological disease characterized by moderate to severe headache and various neurological symptoms. It is often cause mood and anxiety disorders that can seriously affect quality of life. Acupuncture has been claimed to have a role in treating neuropsychiatric disorders and is becoming increasingly popular. However, it remains unclear whether current evidence is sufficient to support acupuncture in improving mental health in migraine patients.

OBJECTIVES

This systematic review and meta-analysis aimed to investigate the effect of acupuncture on the management of pain and mood disorders in patients with migraine.

METHODS

We searched PubMed, Cochrane Library, Embase, Web of Science, Chinese National Knowledge Infrastructure (CNKI) and Wan Fang Data Knowledge Service Platform for reports, conferences and academic papers published before January 1, 2022. Randomized controlled trials (RCTs) including acupuncture, sham acupuncture and medication for migraine were included. Stata 16.0 software and Cochrane RoB2.0 were used for data processing and migration risk analysis.

RESULT

Thirteen randomized controlled trials containing 1766 migraine patients were included in the present study, the results showed that compared with sham acupuncture and medication, acupuncture seemed to have advantage in improving SAS (WMD: -5.64;95% CI: -10.89, -0.39; p = 0.035) and SDS (WMD: -4.65; 95% CI: -9.25, -0.05; p = 0.048) in migraine patients. And it seems to be more effective in improving MH (SMD: 0.77; 95% CI: 0.19, 1.35; p = 0.009), VAS (SMD: -1.06; 95% CI: -1.73, -0.4; p = 0.002;) and MSQ (WMD: 4.76; 95% CI: 2.36, 7.15; p < 0.001) than sham acupuncture and medication.

CONCLUSION

The present results suggest that, compared with Western medicine and sham acupuncture, acupuncture seems to be able to effectively improve anxiety and depression in migraine patients.And it may be more effective in improving SF36-mental health, VAS and MSQ than shame acupuncture or Western medicine. The results of this study need to be verified by higher quality RCTs.

Efficacy of Galcanezumab for Migraine Prevention in Patients With a Medical History of Anxiety and/or Depression: A Post Hoc Analysis of the Phase 3, Randomized, Double-Blind, Placebo-Controlled REGAIN, and Pooled EVOLVE-1 and EVOLVE-2 Studies

OBJECTIVE

This post hoc analysis evaluated the efficacy of galcanezumab for the prevention of migraine in patients with and without comorbid anxiety and/or depression.

BACKGROUND

Patients with migraine have a higher risk of anxiety and/or depression. Given the high prevalence of psychiatric symptoms and their potential negative prognostic impact, determining the efficacy of migraine treatments in patients with these comorbidities is important.

METHODS

The results of 2 phase 3 episodic migraine studies of patients with 4-14 migraine headache days (MHD) per month were pooled. A third chronic migraine study, which was evaluated separately, enrolled patients with ≥15 headache days per month, of which ≥8 had migraine-like features. Patients in all 3 studies were randomized 2:1:1 to placebo, galcanezumab 120 mg, or galcanezumab 240 mg. The efficacy of galcanezumab on migraine was measured in subgroups of patients with anxiety and/or depression (current or past) and patients without. A repeated measures model was used to compare treatment groups within each subgroup and to test for consistency of treatment effect across the anxiety/depression subgroups (subgroup-by-treatment interaction) during the double-blind treatment phases.

RESULTS

Among 1773 intent-to-treat patients with episodic migraine, both doses of galcanezumab demonstrated statistically significant improvements relative to placebo in overall number of MHD for the subgroups of patients with anxiety and/or depression (mean change difference from placebo [95% CI]: -2.07 [-2.81, -1.33] for galcanezumab 120 mg [P < .001], -1.91 [-2.78, -1.04] for 240 mg [P < .001]) and without anxiety and/or depression (mean change difference from placebo [95% CI]: -1.92 [-2.36, -1.47] for 120 mg [P < .001], -1.77 [-2.20, -1.33] for 240 mg [P < .001]), as was observed for the secondary outcomes of MHD with acute medication use and functional impairment. Among 1113 intent-to-treat patients with chronic migraine, those with anxiety and/or depression had significant reductions in overall MHD frequency with the 240-mg dose (mean change difference from placebo [95% CI]: -1.92 [-3.52, -0.33]; P = .018), whereas significant reductions were observed at both the 120-mg (mean change difference from placebo [95% CI]: -2.29 [-3.26, -1.31]; P < .001) and 240-mg (-1.85 [-2.83, -0.87]; P < .001) doses in patients without anxiety and/or depressions. Significant reductions (P < .01) in MHD with acute medication use were observed at both doses within both anxiety/depression subgroups and for overall functional impairment for patients without anxiety and/or depression, though neither dose significantly reduced overall functional impairment beyond placebo in the subgroup with anxiety and/or depression. In the episodic and chronic migraine studies, the subgroup-by-treatment interaction was not statistically significant for MHD, MHD with acute medication use, or functional impairment (chronic study only), suggesting a lack of evidence of differential effect between subgroups. Furthermore, differences between subgroups in the mean change differences from placebo, as well as overlapping 95% confidence intervals for the subgroups, indicated lack of a clinical or statistical difference between subgroups for these outcome variables. There was a significantly higher percentage of patients with episodic migraine attaining ≥50%, ≥75%, and 100% reductions, and a higher percentage of patients with chronic migraine attaining ≥50% and ≥75% reductions from baseline with galcanezumab compared with placebo, regardless of medical history of anxiety and/or depression.

CONCLUSIONS

A medical history of anxiety and/or depression does not seem to interfere with response to galcanezumab among patients with episodic migraine, and both doses of galcanezumab appear efficacious for these individuals regardless of this psychiatric history. Among patients with chronic migraine and comorbid anxiety and/or depression, the 240-mg dose, but not the 120-mg dose, significantly decreased overall MHD, but neither dose resulted in significantly greater functional improvement. Patients with migraine and comorbid anxiety and/or depression often require additional interventions, and this may be more important in chronic migraine.
