Spinal muscular atrophy (SMA) has been known as a clinical entity for 130 yearsis still recognized today as the most severe autosomal recessive neuromuscular disease (5q,13,2) in pediatrics. Until 2015, SMA treatment was limited to ventilatory, nutritional, and physical therapy support. Currently, the existence of genetic treatments: gene modification by inclusion of exon 7 to the SMN2 gene (nusinersen and risdiplam) or insertion of the SMN1 gene through the adeno-associated viral transporter (onasemnogene) have radically modified the clinical evolution of children with SMA,especially if they are treated early. This review details the effects of the 3 treatments currently in use worldwide.

The pediatric neuroimmunology field has made significant progress in the last decade. Now, is possible to recognize primary demyelinating diseases, paraneoplastic syndromes, inflammatory (vasculitis), and granulomatous disorders that affect the central nervous system; at the same time, it is important to exclude neurologic manifestations caused by infections, toxic agents, and metabolic problems. An early diagnosis is imperative to institute treatment as soon as possible, improving outcomes. ⋯ We review the evidence and recommendations for the use of steroids in autoimmune demyelinating diseases, acute disseminated encephalomyelitis, optic neuritis, neuromyelitis optica, multiple sclerosis, among others. We will focus on current therapies, including high doses of intravenous methylprednisolone, followed by its progressive reduction, as well as intravenous immunoglobulin or plasmapheresis as second line therapies. Early institution of these treatments can save the patient's life and decrease their risk of permanent disability.

The International League Against Epilepsy (ILAE) recently socialized the proposed classification for epileptic syndromes of neonatal onset and up to the first 2 years of age, dividing them into self-limited epileptic syndromes and epileptic and developmental encephalopathies (DEEs). In this review we will focus on DEEs, defined as disorders in which there is developmental impairment related to both the underlying aetiology independent of epileptiform activity and epileptic encephalopathy. ⋯ The importance of early recognition of epileptic encephalopathies lies not only in the control of epileptic seizures, but also in stopping deterioration by trying to change the course of the disease. It is essential to know the etiology, avoiding medications that can exacerbate seizures and worsen the course, applying precision m edicine as well as identifying candidate patients for early epilepsy surgery.

Tuberous sclerosis complex is an autosomal dominant genetic multisystemic disorder caused primarily by mutations in one of the two tumor suppressor genes TSC1 or TSC2, resulting in increased activation of the mTOR pathway. Regarding clinical manifestations, a wide range of phenotypic variability exists, with symptoms constellations that may differ in affected organs (brain, skin, heart, eyes, kidneys, lungs), age of presentation and severity, but usually with great impact in biopsychosocial aspects of health and in quality of life. ⋯ Subependymal giant cell astrocytomas may require surgical procedures or mTOR inhibitors treatment. mTOR inhibitors may also be useful for other comorbidities. To improve quality of life of patients with tuberous sclerosis complex, it is essential to be able to deliver an integrated approach by specialized multidisciplinary teams, coordinated with primary care physicians and health professionals, that include access to treatments, attention of psychosocial aspects, and an adequate health care transition from pediatric to adult care.

Attention deficit hyperactivity disorder (ADHD) is the most prevalent and frequent neurodevelopmental disorder in neuropediatrics, child psychiatry and child psychology consultations. The greater awareness of this condition, the information and, above all, the socio-cultural acceptance, has led to an earlier diagnosis, leading to more timely and effective treatment. Individualizing each case through systematic tools such as neuropsychological studies and their neuroanatomical and neurobiochemical correlation, related to ADHD, together with algorithms that analyze executive functions, is essential to indicate the optimal pharmacological treatment, together with the application of appropriate non-pharmacological therapies. Multimodal treatment, with cognitive behavioral intervention and pharmacological treatment, is the most effective therapeutic approach.
