Parkinson’s Disease and Headaches: A Cross‐Sectional Study

Migraine and Tension-type Headache in Parkinson's Disease and Progressive Supranuclear Palsy/Corticobasal Syndrome

Objective

To compare the prevalence and characteristics of migraine and tension-type headache (TTH) among patients with Parkinson's disease (PD), progressive supranuclear palsy/corticobasal syndrome (PSP/CBS), and healthy controls (HCs).

Methods

This cross-sectional study involved the collection of data from consecutive PD (n = 81) and PSP/CBS (n = 21) patients along with 104 HCs. Migraine and TTH were diagnosed using the International Classification of Headache Disorders 3rd edition criteria. Demographic data, PD or PSP/CBS details, and the presence and characteristics of migraine and TTH were collected. Montreal Cognitive Assessment Scale, Patient Health Questionnaire-9, and Pittsburgh Sleep-Quality Index were used to assess cognition, depression, and sleep quality, respectively.

Results

A comparable proportion of PD and PSP/CBS patients reported lifetime headache (46.9% vs 23.8%; P = 0.06). TTH was more common, observed in 84.3%, 100%, and 93.5% of PD, PSP/CBS, and HCs with lifetime headache, respectively. A comparable proportion of participants in all three groups had bilateral (P = 0.10), dull-aching headache (P = 0.09), and occurring <5/month (P > 0.99). The mean severity score of headache among three groups was comparable (P = 0.39). Although the demographic and clinical characteristics of PSP/CBS patients with and without headache were comparable, PD patients with headache had a higher MDS-UPDRS-III score than those without. More than two-third PD and all PSP/CBS patients with lifetime headache reported headache improvement following parkinsonism onset.

Conclusion

The prevalence and characteristics of migraine and TTH were comparable in PD, PSP/CBS, and HCs. Headache was associated with greater motor severity in PD. Following parkinsonism onset, headache improved in the majority of PD and PSP/CBS patients with lifetime headache.

Normal glymphatic system function in patients with new daily persistent headache using diffusion tensor image analysis along the perivascular space

OBJECTIVES

To investigate the glymphatic function in patients with new daily persistent headache (NDPH) using the diffusion tensor image analysis along the perivascular space (DTI-ALPS) method.

BACKGROUND

NDPH, a rare and treatment-refractory primary headache disorder, is poorly understood. There is limited evidence to suggest that headaches are associated with glymphatic dysfunction. Thus far, no studies have evaluated glymphatic function in patients with NDPH.

METHODS

In this cross-sectional study conducted in the Headache Center of Beijing Tiantan Hospital, patients with NDPH and healthy controls were enrolled. All participants underwent brain magnetic resonance imaging examinations. Clinical characteristics and neuropsychological evaluation were examined in patients with NDPH. ALPS indexes for both hemispheres were measured to determine the glymphatic system function in patients with NDPH and healthy controls.

RESULTS

In total, 27 patients with NDPH (14 males, 13 females; age [mean ± standard deviation (SD)]: 36.6 ± 20.6) and 33 healthy controls (15 males, 18 females; age [mean ± SD]: 36.0 ± 10.8) were included in the analysis. No significant differences between groups were observed in the left ALPS index (1.583 ± 0.182 vs. 1.586 ± 0.175, mean difference = 0.003, 95% confidence interval [CI] of difference = -0.089 to 0.096, p = 0.942), or right ALPS index (1.578 ± 0.230 vs. 1.559 ± 0.206, mean difference = -0.027, 95% CI of difference = -0.132 to 0.094, p = 0.738). Additionally, ALPS indexes were not correlated with clinical characteristics or neuropsychiatric scores.

CONCLUSION

No glymphatic dysfunction was detected in patients with NDPH by means of the ALPS method. Additional studies with larger samples are needed to confirm these preliminary findings and improve the understanding of glymphatic function in NDPH.

Migraine, Tension-Type Headache and Parkinson's Disease: A Systematic Review and Meta-Analysis

Background and Objectives: The relationship between migraine and tension-type headache (TTH) with Parkinson's disease (PD) is controversial, while a common pathophysiological link remains obscure. The aim of this systematic review is to investigate the association between PD, migraine and TTH. Materials and Methods: Following PRISMA, we searched MEDLINE, WebofScience, Scopus, CINAHL, Cochrane Library and ClinicalTrials.gov up to 1 July 2022 for observational studies examining the prevalence and/or associations of PD with migraine and TTH. We pooled proportions, standardized mean differences (SMD) and odds ratios (OR) with random effects models. The risk of bias was assessed with the Newcastle-Ottawa scale (PROSPERO CRD42021273238). Results: Out of 1031 screened studies, 12 were finally included in our review (median quality score 6/9). The prevalence of any headache among PD patients was estimated at 49.1% (760 PD patients; 95% CI 24.8-73.6), migraine prevalence at 17.2% (1242 PD patients; 95% CI 9.9-25.9), while 61.5% (316 PD patients; 95% CI 52.6-70.1) of PD patients with migraine reported headache improvement after PD onset. Overall, migraine was not associated with PD (302,165 individuals; ORpooled = 1.11; 95% CI 0.72-1.72).However, cohort studies demonstrated a positive association of PD among lifetime migraineurs (143,583 individuals; ORpooled = 1.54, 95% CI 1.28-1.84), while studies on 12-month migraine prevalence yielded an inverse association (5195 individuals; ORpooled = 0.64, 95% CI 0.43-0.97). Similar findings were reported by 3 studies with data on the TTH-PD relationship (high prevalence, positive association when examined prospectively and an inverse relationship on 12-month prevalence). These data were not quantitatively synthesized due to methodological differences among the studies. Finally, PD patients suffering from any headache had a lower motor unified Parkinson's disease rating scale (UPDRS) score (503 PD patients; SMD -0.39; 95% CI -0.57 to -0.21) compared to PD patients not reporting headache. There is an unclear association of headaches in genetic PD cohorts. Conclusions: Observational data suggest that migraine and TTH could be linked to PD, but the current literature is conflicting.
