Eficácia do uso da Fluoxetina no Tratamento do Transtorno dos Comportamentos Obsessivo-Compulsivo em Autistas / Effectiveness of Fluoxetine use in the Treatment of Obsessive-Compulsive Behavior Disorders in Autistic Persons

RESUMO Objetivo: Verificar a eficácia do uso da fluoxetina no tratamento do transtorno do espectro autista (TEA). Métodos: Efetuou-se uma revisão sistemática da literatura a partir da questão de pesquisa “Em pacientes portadores do transtorno do espectro autista, o uso da fluoxetina em comparação ao placebo, é eficaz no tratamento dessa condição?”. Para seleção dos artigos realizou-se uma busca nas seguintes bases de dados: Biblioteca Virtual em Saúde (BVS) e PUBMED, utilizando-se como critérios de elegibilidade apenas ensaios clínicos randomizados e de qualquer ano. A amostra final foi composta por seis artigos. Resultados: em mais de 60% dos estudos, o tratamento com a fluoxetina resultou na redução dos comportamentos obsessivo-compulsivos encontrados no TEA. Os demais resultados foram conflitantes ou inconclusivos. Conclusão: Embora a maior parte dos estudos tenha apresentado que o uso da fluoxetina como redutor dos comportamentos obsessivo-compulsivo, não se pode asseverar eficácia comprovada devido ao número limitado de pesquisas e pelo pequeno grupo de pessoas que foram randomizadas. Mesmo não havendo uma comprovação “universal” os médicos optam por utilizar este medicamento desde que seja ponderado os riscos e benefícios.

The Emergence of Kleptomania in Children and How to Cope with Therapy

kleptomania in children, signs and triggers of kleptomania in children, and Overcoming Kleptomania in Children. Since committing fraud, the kid would, on the whole, feel satisfied. Kleptomania is often linked to depression or obsessive-compulsive behavior. Kleptomaniacs steal on the spur of the moment, with little prior planning. Kleptomania is caused by a chemical imbalance in the brain that occurs during a head injury. Several approaches to overcoming kleptomania in children can be used, including parental approaches, Islamic approaches, talking to a psychiatrist, giving the child love and encouragement, including the child in athletic activity, psychotherapy and Rational Emotive Counseling, and opioid rehab against the child to discourage the offender from being more serious.

Influence of Diazepino[1,2-a]benzimidazole derivative (DAB-19) on behavioral aspects of animals

Introduction: Diazepino[1,2-a]benzimidazole derivatives showed anxiolytic (EPM, L/D box, Vogel test), antidepressant (Tail Suspension test, Porsolt test), anticonvulsant (Pentylenetetrazole-Induced seizures) and analgesic (Tail-Flick, Hot Plate) actions, which were described earlier (Spasov et al. 2020). 11-(4-tert-butylbenzyl)-2,3,4,5-tetrahydro[1,3]diazepino[1,2-a]benzimidazole hydrobromide (compound DAB-19) has evident anxiolytic, antidepressant and anticonvulsant effects. In the present study, compound DAB-19 was screened for its influence on animals` behavior patterns, such as aggression, obsessive-compulsive behavior, emotional lability, and unsociability. Materials and methods: 112 outbred white animals (rats and mice) were used. Compound DAB-19 (2.34 mg/kg, p.o.) and diazepam (2 mg/kg, p.o.) were injected to the treatment groups. Using an Open Field (OF) test, we evaluated a spontaneous motor activity, a search activity of mice and a degree of their emotionality. During a Marble Burying (MB) test, we monitored anxiolytic and anticompulsive effects of DAB-19. Using a Resident-intruder (RI) test, we evaluated a degree of aggression in the experimental animals, properties of their social interaction, as well as defensive and individual behavior. Results and discussion: Compound DAB-19 has positive influence on the search activity, mood stabilizing activity and antiaggressive actions. Administration of both DAB-19 (2.34 mg/kg, p.o.) and diazepam (2 mg/kg, p.o.) reduced anxiety-like behavior in OP, RI and MB tests, as indicated by a significantly increased number of entries to the center of OP; a decreased number of marbles buried in MB and reduced aggressive behavior in RI. It was stated that using DAB-19 leads to a decrease in affective reactions of the animals – aggression, obsessive-compulsive behavior, neurotic condition and emotional instability. Conclusions: The compound (DAB-19) produces anxiolytic-like effects, compared with those of diazepam, in various anxiety paradigms.

Obsessive-Compulsive Behavior Isn't Necessarily a Bad Thing

It is difficult to believe that in about 1960 practically nothing was known about the thymus and some of its products, T cells bearing αβ receptors for antigen. Thus I was lucky to join the field of T cell biology almost at its beginning, when knowledge about the cells was just getting off the ground and there was so much to discover. This article describes findings about these cells made by others and myself that led us all from ignorance, via complete confusion, to our current state of knowledge. I believe I was fortunate to practice science in very supportive institutions and with very collaborative colleagues in two countries that both encourage independent research by independent scientists, while simultaneously ignoring or somehow being able to avoid some of the difficulties of being a woman in what was, at the time, a male-dominated profession.

Citalopram Improves Obsessive-Compulsive Crossword Puzzling in Frontotemporal Dementia

Behavioral variant frontotemporal dementia (bvFTD) is characterized by severe changes in personality/behavior. Recent studies have provided evidence that a decrease in serotonin receptors and neuronal loss in the raphe nuclei play a role in the bvFTD pathology. Serotonergic antidepressants have been reported to diminish behavioral disturbances in bvFTD, particularly repetitive behaviors, disinhibition, apathy, sexually inappropriate behaviors, and hyperorality. Here, we present the case of an 80-year-old Caucasian male patient with clinically and biomarker supported bvFTD (“probable” bvFTD; disease-specific alterations in 18F-fluorodesoxyglucose positron emission tomography and magnetic resonance imaging). The patient exhibited behavioral disinhibition, apathy, a loss of empathy, perseverative behavior during testing, hyperorality, changes in diet, and executive deficits in neuropsychological testing. Remarkably, he failed in solving crosswords by systematically filling in the blanks by letters in alphabetical order (A, B, C, D, etc.), indicating obsessive-compulsive behavior. One year later, the patient visited the clinic again for a follow-up investigation. He had taken 20 mg of citalopram per day for 1 consecutive year. Remarkably, he had regained the ability to fill in crossword puzzles correctly, although the neuropsychiatric inventory showed overall only small improvement in behavioral impairment. A regimen of 20 mg citalopram per day over the course of 1 year led to a specific improvement in one of the bvFTD core symptoms, obsessive-compulsive behavior, most pronounced in solving crossword puzzles. This case contributes to the understanding of the neuropharmacological correlates of bvFTD and supports the treatment of bvFTD’s behavioral symptoms with selective serotonin reuptake inhibitors.
