[Sleep in chronic neuropediatric diseases].

The prevalence of sleep disorders (SD) is notoriously increased in children with chronic neurological disease, with a negative bidirectional link that aggravates their symptomatology and has a negative impact on the quality of life of the child and their families. Identifying and recognizing this association is key for the child neurologist since the treatment of SD significantly improves daytime symptomatology in neurodevelopmental disorders, epilepsy, primary headaches, cerebral palsy and neuromuscular diseases.

[Arterial ischemic stroke in childhood].

Despite advances in the identification and recognition of risk factors for pediatric arterial ischemic stroke, little progress has been made in hyperacute treatment. The most frequent risk factors are arteriopathies, cardiopathies, and thrombophilia. Early confirmation with neuroradiological studies is key to consider reperfusion therapies, which have limited evidence in pediatrics but a good safety profile.

[Sleep disorders and their impact on neurodevelopment].

Sleep is the main activity of the developing brain and indispensable for the maturation of the central nervous system. Sleep habits are influenced by biological, social and cultural factors and play a role in learning and memory processes. It is estimated that 25-50% of children have sleep difficulties.

[Bilateral paramedian thalamic infraction due artery of Percheron occlusion].

Introduction: Artery of Percheron (AOP) is an anatomical variant responsible for the bilateral irrigation of both the medial thalami and rostral sector of the brainstem. Its obstruction causes infarcts in these areas.

Objective: To describe a clinical case of AOP infarction, highlighting the clinical and imaging fin dings to consider this pathology in the pediatric population with acute altered state of consciousness.
