The impact of insomnia disorder on adult attention-deficit/hyperactivity disorder severity: A six-month follow-up study.

BACKGROUND AND OBJECTIVES: The longitudinal relationship between insomnia disorder and adult attention-deficit/hyperactivity disorder (ADHD) has been scarcely investigated. This study aimed to evaluate the relationship between the remission of insomnia disorder and adult ADHD clinical severity, psychiatric and medical comorbidities, and the health-related quality of life (HRQoL) in a 6-month follow-up. METHODS: Ninety-two adult patients with ADHD and insomnia disorder (52.2% males; mean age 39.5 ± 11.0 years) were comprehensively assessed at baseline, 3 months, and 6 months of a follow-up period. The evaluation included semi-structured interviews (for ADHD and comorbidity assessment), the Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Epworth Sleepiness Scale. The diagnosis of ADHD and insomnia disorder was performed according to DSM-5 criteria. At baseline and follow-up, psychoeducation/sleep hygiene and, if necessary, pharmacological were prescribed for insomnia. RESULTS: Eighty-seven patients completed the 6-month follow-up. Insomnia disorder remission was reported in 72.4% of cases and was related to a greater improvement in ADHD symptoms and severity throughout the follow-up period. Additionally, an improvement in psychiatric comorbidities and better HRQoL were associated with insomnia disorder remission. CONCLUSION: The current study highlights that the treatment of insomnia disorder in ADHD adult patients may have an important role in the outcome of ADHD therapeutic approaches by reducing their severity.

[Drug-induced mania and hypomania: analysis of a case of lamotrigine-induced mania]. / Manía e hipomanía inducida por fármacos: análisis de un caso de manía inducida por lamotrigina.

INTRODUCTION: Lamotrigine is an antiepileptic medication approved as a mood stabilizer for the prevention of depressive episodes in bipolar disorder. Among its adverse reactions, it may present maniac symptoms, despite being an idiosyncratic adverse effect and low incidence. CASE REPORT: We present the case of a 58-year-old patient, diagnosed with bipolar disorder since her youth and who has required multiple therapeutic schemes. After a pharmacological change from lithium to lamotrigine in progressive ascending doses, she presented a mania decompensation, temporally consistent with the initiation of lamotrigine, and that was accentuated with increasing dose. The symptoms disappear when lamotrigine is withdrawn and a pharmacological approach is carried out. When evaluating the case according to the causality criteria of Naranjo et al, we found a possible result. CONCLUSION: Although lamotrigine-induced manifest symptoms have been previously documented, it is important to take this adverse effect into account, given the affective and behavioral repercussions. Further studies are needed to understand the bilateral relationship of this effect from a clinical and neurobiological point of view.

TITLE: Manía e hipomanía inducida por fármacos: análisis de un caso de manía inducida por lamotrigina.Introducción. La lamotrigina es un antiepiléptico aprobado como estabilizador del ánimo para la prevención de episodios depresivos en el trastorno bipolar. Entre sus reacciones adversas puede presentar sintomatología maniforme inducida, a pesar de ser un efecto adverso de carácter idiosincrático y baja incidencia. Caso clínico. Presentamos el caso de una paciente de 58 años, con diagnóstico de trastorno bipolar desde su juventud y que, a lo largo de la evolución de su patología, ha precisado múltiples esquemas terapéuticos. Tras un cambio farmacológico de litio a lamotrigina en dosis ascendentes progresivas, presenta descompensación maniforme, concordante temporalmente con el inicio de la lamotrigina y que se acentúa con el aumento de la dosis. La sintomatología desaparece al retirar la lamotrigina y realizar un abordaje farmacológico. Al evaluar el caso según los criterios de causalidad de Naranjo et al, encontramos un resultado posible. Conclusión. Aunque se ha documentado previamente sintomatología maniforme inducida por lamotrigina, es importante tener en cuenta este efecto adverso, dada la repercusión a nivel afectivo y conductual. Son necesarios más estudios para entender la relación bilateral de este efecto desde un punto de vista clínico y neurobiológico.

Pharmacological Treatment of Insomnia Symptoms in Individuals with Substance Use Disorders in Spain: A Quasi-Experimental Study.

INTRODUCTION: Pharmacological treatment of insomnia in patients with addictions has been hardly investigated and there are few researches about it in an inpatient detoxification. The aim of this study was to describe the outcomes of the pharmacological treatment of insomnia in SUD patients admitted to a detoxification unit in Spain, with a focus on the primary substance of abuse and co-occurring mental disorders. METHODS: A quasi-experimental study was conducted in 481 addicted in patients, who were admitted for substances detoxification in Vall d´Hebron University Hospital, Barcelona, Spain, from 2010 to 2015. The patients underwent systematic evaluation of axes I and II psychiatric disorders (SCID-I, SCID-II, and CAADID). Insomnia was evaluated using a night time sleep log. Substance-dependent patients, who had insomnia during hospital detoxification, received a psychotropic medication with hypnotic effect, keeping the regular clinical practice without randomization. RESULTS: At discharge, insomnia was considered to have been alleviated in 63.8% (n = 204) of patients while 36.2% (n = 116) of patients remained with insomnia disturbances. Comparing hypnotic treatments it was observed that mirtazapine and clotiapine were the treatment that corrected the insomnia more frequently. DISCUSSION: Since insomnia is not corrected in all patients, it should be further investigated in medications with hypnotic purpose. Based on the results of this work, randomized clinical trials might be proposed.

Higher severity of cocaine addiction is associated with tactile and somatic hallucinations.

BACKGROUND: The aim of this study is to describe the features of cocaine-dependent patients who have had cocaine-induced tactile/somatic hallucinations (CITSH), and to analyze the association with addiction-related variables and psychiatric comorbidity, comparing patients with CITSH, patients with cocaine psychotic symptoms (CIP) and no CITSH, and patients without any psychotic symptom. METHOD: A cross-sectional study was conducted in 767 cocaine-dependent patients in an outpatient treatment center for addictions. The following data were obtained: sociodemographic characteristics, CIP information, addiction-related variables and psychiatric comorbidity. A bivariate and multivariate analysis was performed. RESULTS: Of the whole sample, 6.6% reported CITSH at some point of their lives, 48.4% had suffered some CIP other than CITSH, and 45% had not experienced any psychotic symptom. According to multivariate analysis, risk of overdose increases by 12.1 (OR) times the probability of having had CITSH compared patients with CIP-no-CITSH. Other variables associated to patients with CITSH were: age of drug use onset, presence of episodes of overdose, prevalence of psychotic disorder induced by cocaine. In general, in all variables studied, patients with CITSH presented worse clinical features (addiction variables and psychiatric comorbidity) than patients with CIP without CITSH and non-CIP group. CONCLUSION: CITSH are usually associated with other psychotic symptoms induced by cocaine. The patients who experienced CITSH are more severe cases compared both with patients with CIP without CITSH and patients without CIP. Increased risk of overdose is an important issue in this type of patients.
