The outbreak and the quick expansion of SARS-CoV-2, from December 2019 to nowadays, have forced countries around the world to resolve virus containment measures, in order to slow down the contagion curve. Between these measures, the situation of lockdown, as well as the isolation or the limitation of social contact, between the citizens, has caused an unknown psychological impact. Certain groups, (elderly, children and teenagers or clinical population, for instance), produce serious fears between the professionals, due to their greater vulnerability and the ignorance around the short and long-term damages. The main purposes of this work are; first of all to know the lockdown´s consequences in children and teenagers diagnosed with attention deficit hyperactivity disorder (ADHD), sleep related problems and executive functions. Secondly to compare the effects produced on the variables previously mentioned with normotypic subjects, that is to say a group submit to lockdown and another group not confine. The findings show that the clinic confine group has high levels of state-anxiety, sleep and executive functions problems, as well as can be seen differences between both groups, detrimental to ADHD group confined in all measured variables.
