Our case is about a 7-year-old male sent our consulting room to be studied because of a possible ADHD. A low expressive language withizing a speech therapist's treatment. The patient presents symptoms that consist of impulsiveness, low tolerance to the frustration, motive hyperactivity and disruptive behaviour at school and family situations. During his evolution the above mentioned disruptive behaviours are confirmed, the consist if isolate episodes o psycomotive excitement and heteroaggressiveness, most of the time without previous factors which caused it. After the onset of neuroleptic treatment, It's observed a notable improvement about patient's symptomatology, though his case is still been studied.

The bipolar disorder in children and teenagers is a controversial topic from which many studies that support it don’t exist at the moment. It's estimated an advantage of 0.3% – 0.5% in patients under 10-year-old. Its showing is atypical and diffuse, emphasizing the behavioral alterations, the explosivity showed as “effective storms”, the early hyperactivity and the presence of psychotic symptoms, though specific diagnostic criterias for these ages have not been elaborated. As approximately 50% of these patients have been diagnosed of ADHD previously, we consider that this clinical case is important because the main symptoms of Bipolar Disorder appear during the childhood.
