Headache at high school: clinical characteristics and impact.

Although migraine (MH) and tension type headache (TTH) are the most common and important causes of recurrent headache in adolescents, they are poorly understood and not recognized by parents and teachers, delaying the first physician evaluation for correct diagnosis and management. The purpose of this study is to assess the knowledge about headache impact among the students of a Communication Private High School in Rimini city, and to evaluate the main different types of headaches interfering with school and social day activities. A self-administered questionnaire interview was given to students of the last 2 years of high school; ten items assessed the headache experience during the prior 12 months, especially during school time: the features and diagnosis of headaches types (based on the 2004 IHS criteria), precipitating factors, disability measured using the migraine disability assessment (MIDAS); therapeutic intervention. Out of the 60 students, 84 % experienced recurrent headache during the last 12 months. 79 % were females, aged 17-20 years; a family history was present in 74 % of headache students, in the maternal line; 45 % of subjects were identified as having MH and 27 % TTH; 25 % had morning headache and 20 % in the afternoon; fatigue, emotional stress and lack of sleep were the main trigger factors for headache, respectively in 86, 50 and 50 % of students; 92 % of headache students could not follow the lessons, could not participate in exercises and physical activity because of the headache; none had consulted a medical doctor and the 90 % of all students had never read, listened or watched television about headache. This study remarks on the need to promote headache educational programs, starting from high school, to increase communication between teachers-family-physician and patient-adolescents, with the goal to have an early appropriate therapeutic intervention, improvement of the quality of life and to prevent long-term headache disease in the adult age.

Primary headache and epilepsy: a multicenter cross-sectional study.

The prevalence and characteristics of interictal headache, epilepsy and headache/epilepsy comorbidity were assessed in 858 women and 309 men aged 18-81 years from headache and epilepsy centers in Italy. The research hypothesis was that comorbidity among patients with either disorder would be expected to be higher than in the general population. Interictal headache was diagnosed in 675 cases (migraine 482; tension-type headache 168; other types 25), epilepsy in 336 (partial 171; generalized 165) and comorbidity in 156 (1.6% from headache centers; 30.0% from epilepsy centers). Patients with epilepsy, headache and comorbidity differed in a number of demographic and clinical aspects. However, for both headache and epilepsy, a family history of the same clinical condition was equally prevalent in patients with and without comorbidity. These findings do not support the purported association between headache and epilepsy.

Undertreatment in patients with primary headaches attending headache centres.

Undertreatment in patients with primary headaches was evaluated in 600 patients attending 7 headache centres in Lombardy by assessing the rates of acute and prophylactic treatments used before the first visit and the rates of prescription of acute and prophylactic treatments after the visit at the headache centre. Our results clearly showed that most headache patients are likely to receive suboptimal treatments, confirming the utility of headache centres as well as the need for promoting education of GPs and the development of appropriate networks to reduce undertreatment rates, in order to highlight the negative impact caused by primary headache on individuals and on the society.

Underdiagnosis of primary headaches: results of a survey on patients attending headache centres.

Underdiagnosis of primary headaches was evaluated in 504 patients attending six Headache Centres in Lombardy. We found high figures of missed diagnoses (no diagnosis of a specific headache form), and of misdiagnosis (non-concordance between previous diagnoses made by the GP and the final diagnoses given by the headache specialist). We note that underdiagnosis in headache patients may have negative consequences, enhancing the risk of progressive worsening of primary headache syndromes, increasing their impact on individuals and on society, and favouring medication overuse.

Headache and anxiety-depressive disorder comorbidity: the HADAS study.

Psychiatric comorbidity (prevalence and types) was tested in a naturalistic sample of adult patients with pure migraine without aura, and in two control groups of patients, one experiencing pure tension-type headache and the other combined migraine and tension-type headaches. The study population included 374 patients (158, 110 and 106) from nine Italian secondary and tertiary centres. Psychiatric comorbidity was recorded through structured interview and also screened with the Mini International Neuropsychiatry Interview (MINI). Only anxiety and depression were investigated. Psychiatric disorders were reported by 49 patients (14.6%; 10.9% of patients with migraine, 12.8% of those with tension-type headache and 21.4% of those with combined migraine and tension-type headaches). The MINI interview detected a depressive episode in 59.9% of patients with migraine, 68.3% of patients with tension-type headache and 69.6% of patients with combined migraine and tension-type headaches. Depression subtypes were significantly different across groups (p=0.03). Anxiety (mostly generalised) was reported by 18.4% of patients with migraine, 19.3% of patients with tension-type headache, and 18.4% of patients with combined migraine and tension-type headaches. The values for panic disturbance were 12.7, 5.5 and 14.2, and those for obsessive-compulsive disorders were 2.3, 1.1 and 9.4% (p=0.009). Based on these results, psychopathology of primary headache can be a reflection of the burden of the disease rather than a hallmark of a specific headache category.

Bovine spongiform encephalopathy and Creutzfeldt-Jakob disease: facts and uncertainties underlying the causal link between animal and human diseases.

Following an outbreak of bovine spongiform encephalopathy (BSE) in dairy cows in the United Kingdom (UK), 153 definite and probable human cases of new variant Creutzfeldt-Jakob disease (nvCJD) have been reported, almost exclusively in the UK. Although exposure to the BSE agent is the most plausible interpretation for the occurrence of nvCJD, the causal link between the BSE prion and nvCJD is still debated. This review discusses the pros and cons of nvCJD as a separate nosographic entity, the scientific basis for a correlation between BSE and nvCJD, the validity of the current diagnostic criteria for CJD and nvCJD, the contribution of epidemiology to the detection of a causal relation between BSE and nvCJD, and the present and future directions of the epidemiological research on BSE, CJD and nvCJD.
