A study carried out by the members of the Study Group of Cephalea of the Spanish Society of Neurology (SEN) belonging to Vall d'Hebron has evaluated the prevalence of headache among the teenager Spanish population and the kind of headache more frequent within this group, as well as the link of their cephalea with comorbidities and life style.The study published at the Cephalalgia magazine - a scientific publication of the International Society of Cephaleae- had a sample of more than 15000 students with an age rate between 12 and 18 years old, belonging to several high schools of Catalonia."Adolescence is a decisive period for neurodevelopment, as during this period the brain still has lots of neuroplasticity and can adapt its structure and functions to respond in front of demands, experiences and physiological changes of the surrounding. Therefore, the impact of whatever happens to the brain during these years can trigger neuroplastic changes with long term consequences", explains Dr. Patricia Pozo Rosich, head of the Research Group Headache and Neurological Pain of VHIR and Coordinator of the Study group in Headaches of the Spanish Society of Neurology (SEN). "Nevertheless, and even though adolescence is a crucial period for some primary headaches, there is few information about the prevalence and impact of headaches in teenagers. We wanted to carry out this study to have a better knowledge in these aspects and be able to change the impact that headache has in adults", adds.As concluded in this study, 30'5% of teenagers suffer from recurrent headache, being migraine the most common kind in this sector of the population (suffered by 11'3% of the interviewed). Furthermore, almost 33% of the teenagers with headaches had, at least, one episode per week and a bit more than the 44% showed some degree of disability related to their headaches. Nonetheless, more than 73% of the interviewed that suffer headaches have no diagnosis.The study also points out that headache is drastically more frequent in girls (35,1% versus 25,5% of male teenagers), more frequent among teenagers with bad sleeping habits (36,6% vs 27,6%), among those who exercise less or don't have breakfast (37,3% vs 28,4%), smoke (10,5% vs 4,9%), or consume caffeine (30,9% vs 24,7%). On the other hand, no differences linking the academic performance, the education level of the parents, the surrounding or education system has been found. Still, 57% of the students with recurrent headache showed family history with headaches.Moreover, among the most associated comorbidities linked to the headaches, there are the allergies, asthma, chronic pain (besides the headache), and mental health and behavioral problems."Our study reflects that headache is a very common health problem among Spanish teenagers, which affects their life quality. Due to the association of the headache with a less healthy / unhealthy lifestyle ad with other medical comorbidities, the Spanish Society of Neurology finds necessary to start implementing educational initiatives that minimize the impact of this disease", points out Dr. Patricia Pozo Rosich.
