[Autistic spectrum disorders, attention deficit disorders, hyperactivity and emotional dysregulation: masking and approach].

Autism Spectrum Disorders (ASD) and Attention Deficit Hyperactivity Disorders (ADHD) are Neurodevelopmental Disorders (ND) that frequently coexist together and have etiological, biological, and clinical factors in common. The comorbidity of both neurodevelopmental disorders is associated with a delay or lack of ASD diagnosis and the development of perceptual, emotional, cognitive and behavioral alterations related to Emotional Dysregulation (ED) is common. When both TN are not diagnosed in childhood, they frequently receive wrong diagnoses at later ages, the most frequent being Borderline Personality Disorder (BPD). The clinical presentation of the association of ASD and ADHD, the association with ED, differentiation of BPD, and evaluation and intervention are here analyzed. The comorbidity ASD, ADHD, ED is a more severe disorder associated to polypharmacology and hospital admissions.
