    This disorder appears to be a relatively common in pediatric population. Its ocurrence is associated with significant morbidity, comorbidity and functional impairment in adults, surprisingly few studies investigating the psychopathology of trichotillomania actually they included teenagers or children. Recent reviews have shown the efficacy of cognitive-behavioral pediatric trichotillomania, therapy but have also noted problems with relapse; these same reviews have mentioned the general lack of benefit associated with treatment only with selective inhibitors of serotonin reuptake. Recent developments in pharmacotherapy has been suggested that other medicines atypical antipsychotics, opioid blockers and modulators glutamate are promising as treatments for trichotillomania, both children and adults. This article has the overall objective to conduct a general review of the prevailing trends in pediatric trichotillomania, emphasizing the evaluation of pathology and the most current treatment recommendations. The Grimm Brothers,

    Although such therapies era promising, more effective drugs in combat of symptoms such as anxiety and irritability are lacking, as well as reducing symptoms in a broader way without pronounced side effects. Autism was first referenced in by the researcher Bleuler, being characterized by the same as, the loss of contact with reality, later in the 40s, Kanner published studies related to the theme, in his reports, he exposed, among other psychopathological characteristics, the Difficulty for autistic children to remember people who were present in their childhood [2].

    Regarding of its etiology, autism has several gaps in relation to its causes, starting from this assumption, we have as main known causes the genetic predisposition, as the expression of specific genes that culminate in the appearance of ASD or even rare mutations without previous cases in the family, its etiology is also linked to environmental factors that interfere with the development of the individual, for example possible early lesions that may affect the cerebellum, which may indicate one of the greatest ASD development risks.

    Serotonin plays a crucial role in autism pathology, since it is a neurotrophic agent during the early stages of human development, so changes in the transport of this neurotransmitter during this stage of life lead to neurological damages that may lead to the development of disorders, such as autism and also epilepsy [3,4,5]. Despite the various hypotheses presented and some scientific confirmations of the pathophysiological characteristics of ASD, its pathogenesis is still controversial and in many points unknown [6,7].

    The treatment of autism consists of methods that seek to reduce its symptoms as well as reduce the number of episodes that cause major disorders, such as gene therapies not yet analyzed in this case , behavioral therapies with the presence of psychologists and psychiatrists, and finally, pharmacological therapies, among them, stimulants, tricyclic antidepressants, selective serotonin reuptake inhibitors SSRIS , mood stabilizers and dopamine antagonists [7,8,9,10].

    Administration of atypical antipsychotics is Currently one of the most widely used pharmacological therapies in ASD, its greatest differential in relation to typical or first generation antipsychotics, although it has some advantages, especially in its lower rate of reported side effects such as www. The analyzed drugs in the present review were Risperidone and Aripiprazole, second-generation drugs, which are reported in the literature as having considerably positive pharmacological effects, such as less aggressive reactions than first generation antipsychotics [11,12,13].

    After initial survey, Title and Abstract had been read. The main criterion for identifying an atypical antipsychotic is the significant difference between doses required to induce antipsychotic effect and extrapyramidal effects. The action mechanisms of these drugs can be observed in diverse ways, they may be total or partial antagonists of dopaminergic receptors, specifically D2 and D4 receptors associated or not with 5-HT receptors, as well as being antagonists of serotonergic, noradrenergic, histaminergic, cholinergic receptors and also act in the gonadotropic modulation or in the prefrontal cortex [14,15,16].

    This class of drugs emerged in the mids, in Europe, with the discovery of Clozapine. However, it was observed that this drug formed granulocytopenia, which led to its withdrawal from the market. However, in , clozapine was again important as an antipsychotic drug after a clinical study by Herbert Meltzer researchers, who observed improvement of symptoms without extrapyramidal effects [17,18].

    Currently there are several atypical drugs, risperidone, aripiprazole, amisulpride, clozapine, paliperidone, olanzapine, quetiapine, ziprasidone, asenapine, iloperidone, lurasidone and cariprazine. Initially, atypical drugs are used in clinical practice for the refractory treatment of schizophrenia.

    After studies, in , risperidone and aripiprazole were approved by the US Food and Drug Administration FDA as a treatment of autism aimed at improving the symptoms of irritability, aggression and self-injury in children and adolescents [19,20]. Risperidone Risperidone is a second-generation antipsychotic drug that is very used for ASD worldwide.

    The use of this medication started in when it was approved by U. Food and Drug FDA , initially for the treatment of schizophrenia in adults. Later, in , the FDA also approves the risperidone use for treating irritability, aggression and hyperactivity related with ASD in adults and children, at least 5 years old.

    This drug is one of the few antipsychotic medications suitable for pediatric patients [21,22,23]. The risperidone action mechanism is associated with the high affinity for D2 and 5-HTA2 dopamine and serotonin receptors, respectively. However, has also affinity for other receptors, like a1-adrenergic, a2-adrenergic and H1-histaminergic.

    It is believed that those dopamine and serotonin receptors antagonisms is responsible for the benefits effects in some ASD symptoms and reduced the extra pyramidal symptoms compared with typical antipsychotic [24, 25, 26].

    Risperidone use in the ASD treatment is available in oral formulations, like tablets 0. The recommendation doses according to FDA depends of the tolerability and response of the patient, in most of the cases the effective dose range is between 0.

    The potential efficacy in the irritability and aggressive behavior control was show in various acute studies, one of them was a double-blind study in children and adolescents 5 to 17 years old who was given daily doses of risperidone for eight weeks when compared with the control group that was receiving placebo.

    Long-term studies were also developed, one of them with children and adolescents years of age during However, clinic trials were showing adverse effects associated with use of this medication, like increased appetite, weight gain, hyperprolactinemia, enuresis, somnolence, fatigue, sedation, pyrexia, and upper respiratory tract infection. A recent review about the pharmacotherapies in the ASD treatment emphasizes that this medication administration should be based on the individual patient analysis need, considering the potentials risks and the therapy benefits [33,34,35].

    Second-generation antipsychotics, often called atypical antipsychotics, have a lower propensity to cause TD tardive dyskinesia and EPS extrapyramidal symptoms.

    Studies have shown that this drug was approved to treat schizophrenia, mixed and manic states of bipolar I disorder as monotherapy or as an adjunct to either lithium or valproate and as adjunctive treatment for major depressive disorder MDD in adults. Aripiprazole has been evaluated in several open label studies and two large placebo-controlled trials in children with autistic disorder. In these studies, this drug has been found to be effective in the treatment of children and adolescents with irritability associated with autism [36].

    It is important to note that the aripiprazole is a partial agonist at the D 2 dopamine , D3 and 5-HT1A serotonin receptors. The effects, at these kind of receptors, are hypothesized to be the mechanism of action for all indications. Partial agonism at 5-HT1A has anxiolytic effects, and is also hypothesized to be associated with reduced risk of EPS [37,38,39].

    Evidence from two randomized controlled trials suggests that aripiprazole can be effective in treating some behavioral aspects of ASD in children. After treatment with aripiprazole, children showed less irritability, hyperactivity, and stereotypies repetitive, purposeless actions. Aripiprazole is presented in different pharmaceutical and dosage forms, such as tablets 2; 5; 10; 15; 20 and 30 mg , oral solution up to 25 mg , orally disintegrating tablets 10; 15 mg and injection solution 5.

    Although aripiprazole has been noted to be safe and generally well tolerated in most of the studies in PDDs pervasive developmental disorders , some concern remains over its propensity to cause weight gain, EPS and sedation common one. Moreover, there are also some other side effects, which sometimes may occur, such as change in prolactin and abnormal movements mild sialorrhea and tremor; muscle stiffness [39,40].

    This class of drugs apparently has few side effects and in most cases they are effective, but in a limited range of symptoms of ASD, it is necessary that other pharmacological and adjuvant therapies be evaluated as a new therapeutic approach in the treatment of ASD.
