Yangxue Qingnao Granules (Pills)Drug
Participants who, in routine clinical practice, were prescribed Yangxue Qingnao Granules/Pills for acute headache relief and/or preventive management were enrolled. Treatment initiation, dosing, frequency, and duration were determined by the treating physician and the patient and were not assigned by the study protocol. During the 12-week observation period, participants were followed and outcomes were recorded, including relief of up to four headache episodes (for those using the medication for acute treatment) and longitudinal symptom measures at weeks 4, 8, and 12 (for those receiving preventive management).

What is being measured
The primary outcome is the main question the study is designed to answer.
Headache Days
The number of days of headache is the number of days in which headache occurs.
Measured: long term: 10 years
MRI change
Patients will accept MRI scans will be done at baseline and once per year.
Measured: long term: 10 years
Genetic analysis of familial headache
Blood samples will be collected from all participants who consent to participate in the study, for the purposes of genetic analysis of familial headache.
Measured: 1 year
Montreal Cognitive Assessment (MoCA)
The Montreal Cognitive Assessment (MoCA) will be used to assess changes in cognitive functions.
Measured: long term: 10 years
Mini-Mental State Exam (MMSE)
The Mini-Mental State Examination (MMSE) is a 30-point questionnaire that is used in clinical and research settings to assess cognitive function.
Measured: long term: 10 years
Migraine Disability Assessment (MIDAS)
The MIDAS is a 7-item questionnaire designed to quantify headache-related disability over a 3- month period. The MIDAS score is the sum of missed work or school days, days at work or school plus days of household work where productivity was reduced by half or more, missed household work days, and missed non-work activity days due to headaches in the last 3 months.
Measured: long term: 10 years
Generalized Anxiety Disorder (GAD-7)
GAD-7 is a proven, self-administered and concise tool for screening and diagnosing mental health disorders, which has been tested in the field in office practice. The GAD-7 scale score ranges from 0 to 21.
Measured: long term: 10 years
Patient Health Questionnaire (PHQ)-9
The PHQ-9 is the depression module, which scores each of the 9 DSM-IV criteria as "0" (not at all) to "3" (nearly every day). A PHQ-9 score total of 0-4 points equals "normal" or minimal depression. Scoring between 5-9 points indicates mild depression, 10-14 points indicates moderate depression, 15-19 points indicates moderately severe depression, and 20 or more points indicates severe depression.
Measured: long term: 10 years
Pain freedom at 2 hours
It refers to the complete resolution of headache symptoms within 2 hours after taking the investigational drug, without the use of any rescue medication, and without recurrence of headache during this period.
Measured: 2 hours post-dose
Secondary outcomes (17)
Social and demographic data, medical history
Social and demographic data, medical and medication history will be collected at initial screening.
Measured: long term: 10 years
Use of Rescue Medication
Frequency of Rescue medication will be collected by eDiary.
Measured: long term: 10 years
Moderate / Severe Headache Days
Moderate / severe headache days are defined as a day in which moderate or severe pain persists for at least 4 hours, or headache lasts for one day after successful medication for acute headache. These definitions allow the use of relatively simple headache diaries. Subjects were required to indicate whether headache was present (yes / no), peak (mild / moderate / severe) severity and duration (< 4h or 4h), type of acute drug intake, and response to treatment should also be recorded.
Measured: long term: 10 years
Pain severity
Pain severity were captured through Visual analogue scale (VAS) for pain, a continuous scale comprised of a horizontal line, anchored by "no pain" (score of 0) and "worst imaginable pain" (score of 10).
Measured: long term: 10 years
MEG
Patients will accept MEG.
Measured: long term: 10 years
PET
Patients will accept PET scan.
Measured: long term: 10 years
EEG
Patients will accept EEG scan.
Measured: long term: 10 years
Proteomics
Blood, urine and Cerebrospinal fluid samples will be collected from all participants who consent to participate in the study, for the purposes of Proteomics at baseline and month 12.
Measured: 1 year
Microbiome
Saliva samples will be collected from all participants who consent to participate in the study, for the purposes of Microbiome at baseline and month 12.
Measured: 1 year
Headache Impact Test (HIT-6)
The HIT-6 is a 6-question assessment used to measure the impact headaches have on a participant's ability to function on the job, at school, at home, and in social situations. It assesses the effect that headaches have on normal daily life and the participant's ability to function.
Measured: long term: 10 years
European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L)
EQ-5D-3L is a generic instrument for use as a measure of health status. The EQ-5D-3L consists of 2 components-the EQ-5D descriptive system and the EQ VAS. The descriptive system comprises of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). The respondent is asked to indicate his/her health state by ticking (or placing a cross) in the box against the most appropriate statement in each of the 5 dimensions.
The EQ VAS records the respondent's self-rated health on a vertical, VAS where the endpoints are labelled "Best imaginable health state" and "Worst imaginable health state." The scoring range of the EQ VAS is from 0 (worst imaginable health) to 100 (best imaginable health).
Measured: long term: 10 years
Migraine Specific Quality of Life Questionnaire, Version 2.1 (MSQ v2.1)
The MSQ v2.1 is a 14-item questionnaire designed to measure health-related quality-of-life impairments attributed to migraine in the past 4 weeks. It is divided into 3 domains: Role Function Restrictive assesses how migraines limit one's daily social and work-related activities; Role Function Preventive assesses how migraines prevent these activities; and the Emotional Function domain assesses the emotions associated with migraines.
Measured: long term: 10 years
Pittsburgh Sleep Quality Index (PSQI)
The Pittsburgh Sleep Quality Index (PSQI) is an effective instrument used to measure the quality and patterns of sleep.
Measured: long term: 10 years
Columbia-Suicide Severity Rating Scale
C-SSRS will be administered to study subjects at each study visit to assess possible suicidal ideation and behavior. Reports of suicidal ideation with intent to act (endorse item 4 or 5) and reports of actual, aborted, or interrupted suicide attempts or a behavior preparatory for making an attempt indicate subjects at high risk for suicide.
Measured: long term: 10 years
Absence of the most bothersome symptom
It refers to the complete resolution of the patient's self-identified most bothersome migraine-associated symptom (including photophobia, phonophobia, nausea, etc.) within 2 hours after taking the study medication.
Measured: 2 hours post-dose
Patient Global Impression of Change (PGIC) Scale
The Patient Global Impression of Change (PGIC) Scale is a single-item, patient-reported measure of overall change in symptoms, activity limitation, mood, and overall quality of life since starting treatment at this institution. Scores range from 1 to 7, where 1 = no improvement (or condition worsened) and 7 = very large improvement; higher scores indicate better improvement (better outcome).
Measured: 10 years
Fatigue Impact Scale (FIS)
Fatigue Impact Scale (FIS) is a standardized questionnaire assessing the impact of fatigue on daily functioning (cognitive, physical, and psychosocial domains). Each item is scored 0-4; the total score ranges from 0 to 160 (sum of 40 items). Higher scores indicate greater fatigue impact (worse outcome).
Measured: 10 years
