A Survey Study to Assess the Accessibility of the Nerivio Device At School

This is a retrospective survey-study to assess the accessibility, preference, and frequency of adolescents using Nerivio by itself, in combination with pharmacological medications, or not at all, in the school setting. The study population is prescribed Nerivio users, under the age of 18 years old, who have used the Nerivio device at least once.

Study group: Participants will be recruited from Nerivio's user database. An invitation message will be sent via emails and/or in-app notifications to Nerivio users who are (1) under the age of 18 years old, and (2) treated with Nerivio at least once. Adolescents who meet these criteria will be invited to answer a screening questionnaire verifying eligibility.

Adolescents who are found eligible will be offered the opportunity to participate in the study. If they are willing, they will first be directed to an Informed Consent Form (e-ICF) to be signed by the participant's parent/legal guardian. A copy of the completed form will be automatically sent to the parent/legal guardian upon completion. If the parent/legal guardian consents via the e-ICF to his/her child's participation, an electronic assent form will follow and must be signed by the adolescent patient. A copy of the assent form will be automatically sent to the parents and the adolescent patient. Once both electronic consent forms are signed, the adolescent patient will be enrolled in the study and will be directed to the study survey.

Primary outcome measures:

Percent of adolescents' who prefer treating headaches due to migraine when they are at school with Nerivio alone, relative to other options (combination, pharmaceutical, not treating while in school).

Secondary outcome measures:

1. \- Distribution of barriers to adolescents who report the necessity to treat their headaches due to migraine while at school, including the need to leave class for treatment, lack of availability of treatments while at school, and time delay to treat headaches.
2. \- Distribution of treatments used by adolescents at school to treat migraine headaches prior to being prescribed Nerivio (specific pharmaceutical agents, or not treating at all) reflecting convergence to using Nerivio at school.

• Nerivio (Device): Nerivio is a prescribed Remote Electrical Neuromodulation (REN) device for treatment of migraine

Primary outcomes

• Nerivio usage at school [1 year]: Percent of adolescents who prefer treating headaches due to migraine when they are at school with Nerivio alone, relative to other options (combination, pharmaceutical, not treating while in school).

Secondary outcomes

• Limitations to migraine treatment at school [1 year]: Distribution of barriers to adolescents who report the necessity to treat their headaches due to migraine while at school, including need to leave class for treatment, lack of availability of treatments while at school, time delay to treat headaches.
• Types of migraine treatments during school [1 year]: Distribution of treatments used by adolescents at school to treat migraine headaches prior to being prescribed Nerivio (specific pharmaceutical agents, or not treating at all) reflecting convergence to using Nerivio at school.

Sex: All, ages: any to 18 Years

Inclusion Criteria:

* Age ≤18 years old at registration to the Nerivio app
