The QOL of adolescent migraine sufferers may be aggravated not only by migraine but also by other factors, such as anxiety and depressive symptoms, which may contribute to the poor QOL in adolescents suffering from migraine.

Neurofibromatosis type 1 is characterized by nerve sheath neurofibromas associated with a number of additional clinical features, including cerebrovascular disease. The aim of this study was to use transcranial Doppler as a screening method for identifying cerebral vasculopathy in children with neurofibromatosis type 1. Forty children with neurofibromatosis type 1, aged 5 to 18 years old, were examined by transcranial Doppler. Patients presenting with hemodynamic features of arterial stenosis/occlusion on transcranial Doppler underwent magnetic resonance angiography to confirm the findings. Magnetic resonance angiography was performed on 4 children who exhibited a transcranial Doppler hemodynamic pattern indicative of cerebral vasculopathy. Among these cases, 2 presented internal carotid artery stenosis/occlusion, 1 had bilateral middle cerebral artery stenosis, and 1 presented a normal magnetic resonance angiography result. Transcranial Doppler can be used routinely in the investigation of cerebrovascular disease in neurofibromatosis type 1 patients, where magnetic resonance angiography can be subsequently applied to confirm the diagnosis, further contributing to the prevention of cerebrovascular events.

Introduction: Sickle cell disease is the most prevalent hereditary disease in the country. The aim of this study was to use transcranial Doppler as a screening method for identifying cerebral vasculopathy in children with sickle cell disease. Methods: An epidemiologic, descriptive, and cross-sectional study was conducted. Patients aged 2-16 years with sickle cell disease and followed at a neurology referral service between January 2014 and March 2020 underwent transcranial Doppler and complementary examinations to screen for cerebral vasculopathy. Results: Screening and confirmatory examinations diagnosed 14 of 164 patients (8.5%) with cerebral vasculopathy. Regarding stroke risk, as measured by cerebral blood flow velocity, 2 of 14 patients (14.2%) were classified as conditional risk (170-199 cm/s) and 12 of 14 (85.7%) as high risk of stroke. Conclusion: Complementary examinations should be performed in all patients with changes on transcranial Doppler to confirm cerebral vasculopathy. Further studies, particularly genetic, are needed to better understand the relationship between sickle cell disease and cerebral vasculopathy.
