Psychosis induced by abuse of ayahuasca: a case report / Psicosis inducida por el abuso de la ayahuasca: un caso clínico

A B S T R A C T Ayahuasca is a psychotropic infusion prepared by boiling the bark of Amazonian plants and has many psychopharmacological effects not fully understood. Some of those effects are used as treatment for different diseases. However, the side effects of ayahuasca, including ayahuasca-induced psychosis, are an important issue. Here we report the case of a patient who had a psychotic episode after taking ayahuasca and who was successfully treated with antipsychotic medication. Given the current spread of ayahuasca consumption in developed societies, the present case highlights the need for better understanding and regulation of the social-legal condition of ayahuasca and the need for further research. Additionally, psycho-education seems advisable in order to create awareness of the potential risks of the use of ayahuasca.

RESUMEN La ayahuasca es una bebida psicotrópica preparada a través de la cocción de plantas de la cuenca amazónica que tiene muchos efectos psicofarmacológicos no del todo estudiados. Algunos de esos efectos son usados como tratamiento de diversas patologías. Sin embargo, existen efectos secundarios de la ayahuasca que deben ser tenidos en cuenta, entre ellos psicosis inducida por ayahuasca. Reportamos un caso de un paciente que, tras autoadministración de ayahuasca, presentó un episodio psicótico y que fue satisfactoriamente tratado con antipsicóticos. Dada el uso cada vez más frecuente de ayahuasca en las sociedades desarrolladas, el caso actual resalta las necesidades de entender, regular e investigar el uso de la ayahuasca. Además, crear conciencia de los potenciales riesgos del uso de ayahuasca a través de la psicoeducación debería ser implementado.

Attention Deficit Hyperactivity Disorder Increases Nicotine Addiction Severity in Adults Seeking Treatment for Substance Use Disorders: The Role of Personality Disorders.

AIMS: To examine the role of attention deficit/hyperactivity disorder (ADHD) and impulsive personality disorders in nicotine addiction severity among treatment-seeking substance use disorder (SUD) patients. METHODS: In a cross-sectional study, we examined data from the second International ADHD in Substance Use Disorders Prevalence Study (IASP-2) on 402 adults in SUD treatment from Puerto Rico, Hungary, and Australia using diagnostic interviews for ADHD, antisocial (ASP) and borderline (BPD) personality disorders, and the self-report Fagerström Test of Nicotine Dependence (FTND). We compared SUD patients with and without ADHD on nicotine addiction severity. We tested direct and indirect pathways from ADHD to nicotine addiction and mediation through ASP and BPD. RESULTS: Overall, 81.4% of SUD patients reported current cigarette smoking. SUD patients with ADHD had higher FTND scores and smoked more cigarettes than those without ADHD, with an earlier onset and more years of smoking. ASP mediated the effect of ADHD on all aspects of nicotine addiction severity, whereas BPD did so only on some aspects of nicotine addiction severity. CONCLUSIONS: SUD patients with comorbid ADHD show more severe nicotine addiction than those without, which is largely explained by comorbid impulsive personality disorders. In SUD patients, it is important to screen for adult ADHD and other psychiatric disorders, especially those with impulse control deficits such as ASP and BPD.

Self-perceived quality of life in cocaine dependents with or without dual diagnosis / Calidad de vida autopercibida en pacientes dependientes de cocaína con o sin diagnóstico de patología dual

INTRODUCTION: Although impairment in the quality of life is common among cocaine dependent patients, there are but a few researches about the interaction between addiction and quality of life. OBJECTIVE: To study different parameters of quality of life in a sample of cocaine dependent patients and to compare patients with or without dual diagnosis. Also, to promote the importance of subjectivity in the quality of life and to propose to incorporate patients' self-perception into their treatment. METHOD: Three diagnostic interviews were administered (SCID-I, SCID-II and PRISM) and a quality of life questionnaire (SF-36) was applied between two different patient groups: Group I (cocaine dependent patients) and Group II (cocaine dependent patients with other mental disorder). RESULTS: Patients diagnosed with dual disorders (Group II) showed broader differences in perceptions of their quality of life in comparison with their clinicians. The perception of quality of life may vary depending on the presence and severity of mental disorders, and these different appreciations may explain the difficulties that clinicians face in understanding their patients' expectations and motivations. DISCUSSION AND CONCLUSION: A systematic evaluation of the subjective quality of life should be included in the management of cocaine dependent patients in order to more accurately understand the patients' perception of their treatment, motivations and expectations.

INTRODUCCIÓN: La calidad de vida de los pacientes dependientes a la cocaína se encuentra alterada y hay poca información acerca de cómo interactúa la dependencia a sustancias y la calidad de vida. OBJETIVO: Estudiar los diferentes parámetros de calidad de vida en pacientes dependientes a la cocaína con o sin diagnóstico de patología dual. Asimismo, señalar la importancia de la subjetividad en la calidad de vida y proponer la incorporación de la autopercepción de los pacientes en su tratamiento. MÉTODO: Se realizaron tres entrevistas diagnósticas (SCID-I, SCID-II y PRISM) y un cuestionario de calidad de vida (SF-36) entre dos grupos diferentes de pacientes: Grupo I (pacientes con dependencia a la cocaína solamente) y Grupo II (pacientes dependiente a la cocaína con otro trastorno mental). RESULTADOS: Los pacientes diagnosticados con patología dual (Grupo II) mostraban amplias diferencias en la percepción de la calidad de vida comparada con la percepción de sus terapeutas. La percepción de la calidad de vida podría variar dependiendo de la presencia y gravedad de los trastornos mentales asociados. Además, estas diferentes apreciaciones podrían explicar las dificultades que tiene el clínico para entender las expectativas y motivaciones del paciente de cara a su tratamiento. DISCUSIÓN Y CONCLUSIÓN: En pacientes dependientes a la cocaína debería realizarse de forma sistemática una evaluación de la calidad de vida subjetiva con el fin de conocer con mayor precisión la percepción que tienen los pacientes de su tratamiento, así como sus motivaciones y expectativas.
