ABSTRACT
BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder among children but symptoms may persist into adulthood. At Landspitali - the National University Hospital an interdisciplinary unit is responsible for ADHD-diagnosis and for commencing treatment of adult ADHD. The aim of this study is to evaluate the effectiveness of pharmaceu-tical treatment provided by the unit and the effects of psychiatric comorbidities. METHODS: The study is retrospective and includes all individuals ≥18 years of age who received pharmaceutical treatment in the adult ADHD unit at Landspitali 2015-2017. Individuals who had previously received treatment by the unit or were already on medication for ADHD were excluded. Information on symptoms and wellbeing before and after treatment were obtained from three questionnaires, an ADHD rating scale, DASS and QOLS. RESULTS: Of 211 patients who met inclusion criteria 144 (68%) completed the treatment provided by the unit on average 143 days. Impulsivity/hyperactivity predicted treatment failure with OR=0.96 (p=0.015). There was a statistically significant difference in all key response variables before and after pharmaceutical treatment (p<0.001). The Cohen's d effect size for ADHD variables were 3.18 for attention-deficit and 1.40 for impulsivity/hyperactivity. The effect size for quality of life was 1.00 and among the DASS subscales the maximum effect size was 1.43 for stress. Increased quality of life correlated with decreased symptoms as rated by DASS and the ADHD rating scale. Treatment success rates were significantly -higher for DASS but not for attention-deficit, impulsivity/hyperactivity and quality of life among individuals with psychiatric comorbidities alongside ADHD. Gender did not affect treatment effectiveness. CONCLUSIONS: Those who complete treatment within the ADHD unit achieve good results with decreased psychiatric symptoms and improved quality of life. Treatment discontinuation is a challenge.

RESUMEN El trastorno por déficit de atención e hiperactividad (TDAH) es la alteración neuroconductual más frecuente en la consulta pediátrica y su tratamiento comprende la terapia comportamental y el empleo de fármacos. Existe una preocupación latente por el eventual desarrollo del trastorno por el uso de sustancias (TUS) en los pacientes con TDAH tratados con estimulantes. La evidencia médica sugiere un efecto protector con respecto al consumo de sustancias psicoactivas, pero también alerta sobre el potencial abuso por parte de los pacientes y las personas alrededor. En este artículo se revisan sistemáticamente las virtudes y los riesgos de desarrollar TUS en los pacientes con TDAH en tratamiento con estimulantes.
SUMMARY The attention deficit with hyperactivity disorder is the most frequent disorder in pediatric outpatient services and its treatment involves behavioral therapy and drugs. However, there is concerning about develop substances use disorder once upon treatment with stimulants. Medicine based evidence suggests a preventive effect about psychoactive substance consumption but also warns potential abuse by patients and people around. In this paper, we systematically review worths and risks of SUD in stimulant - treated ADHD patients.

El Trastorno por Déficit de Atención con Hiperactividad (TDAH), es una de las alteraciones del neurodesarrollo de mayor prevalencia; su trinomio sintomático de desatención, hiperactividad e impulsividad, genera significativas dificultades en distintos contextos en donde se desenvuelve el niño. Este trabajo presenta el estudio de caso de un niño de 11 años, diagnosticado con TDAH con predominio de déficit de atención (TDAH-DA), medicado con metilfenidato (MFD) a 36 mg. Se buscó analizar y comparar las diferencias en el desempeño de atención y funciones ejecutivas, evaluadas a través de la batería neuropsicológica Monitoreo Cognitivo Computarizado, en relación a la presencia o ausencia de medicación. Los resultados permiten evidenciar como la suspensión de la mediación en este caso afectó el sistema pre-atencional, la atención sostenida y la flexibilidad cognitiva, y no así la atención selectiva, la fluencia de lectura, la capacidad de nominación y el output motor, en especial de la mano izquierda, los cuales incluso obtuvieron un mejor desempeño al suspenderla. Este estudio plantea los beneficios del MFD en el sistema pre-atencional y atención sostenida más que en la atención selectiva y su influencia en el detrimento de la velocidad de procesamiento.
The Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders. Its symptomatic trinomial of inattention, hyperactivity and impulsiveness generates significant difficulties within several contexts in which the child evolves. This work shows a case study of an 11-yearoldboy, diagnosed with ADHD subtype: inattentive, medicated with methylphenidate (MPH) 36mg. The aim of this study was to analyze and compare the differences regarding the development of attention and executive functions, assessed through the neuropsychological battery Cognitive Computerized Monitoring related with the presence or absence of medication. In this case, the results show how withdrawing the medication affects the pre-attentional system, sustained attention and cognitive flexibility. On the other hand, the results demonstrate that the cessation of medication does not affect selective attention, Reading fluency, naming capacity and motor output, especially the right hands motor output that even showed better performance when suspending medication. This study confirms the benefits of MPH in the pre-attentional system and sustained attention, more than selective attention and its influence in the detriment of processing speed.
