Bipolar I and II versus unipolar depression: clinical differences and impulsivity/aggression traits.

OBJECTIVE: To investigate distinguishing features between bipolar I, II and unipolar depression, and impulsivity/aggression traits in particular. METHODS: Six hundred and eighty-five (n=685) patients in a major depressive episode with lifetime Unipolar (UP) depression (n=455), Bipolar I (BP-I) disorder (n=151), and Bipolar II (BP-II) (n=79) disorder were compared in terms of their socio-demographic and clinical characteristics. RESULTS: Compared to unipolar patients, BP-I and BP-II depressed patients were significantly younger at onset of their first depressive episode, and were more likely to experience their first depressive episode before/at age of 15. They also had more previous affective episodes, more first- and second-degree relatives with history of mania, more current psychotic and subsyndromal manic symptoms, and received psychopharmacological and psychotherapy treatment at an earlier age. Furthermore, BP-I and BP-II depressed patients had higher lifetime impulsivity, aggression, and hostility scores. With regard to bipolar subtypes, BP-I patients had more trait-impulsivity and lifetime aggression than BP-II patients whereas the latter had more hostility than BP-I patients. As for co-morbid disorders, Cluster A and B Personality Disorders, alcohol and substance abuse/dependence and anxiety disorders were more prevalent in BP-I and BP-II than in unipolar patients. Whereas the three groups did not differ on other socio-demographic variables, BP-I patients were significantly more often unemployed that UP patients. CONCLUSION: Our findings comport with major previous findings on differences between bipolar and unipolar depression. As for trait characteristics, bipolar I and II depressed patients had more life-time impulsivity and aggression/hostility than unipolar patients. In addition, bipolar I and II patients also differed on these trait characteristics.

Parents with bipolar disorder: are disease characteristics good predictors of psychopathology in offspring?

PURPOSE: To investigate rates of psychopathology in the offspring of subjects with bipolar disorder (BP-offspring) compared to the offspring of healthy subjects (HC-offspring) in a Spanish sample and to study possible predictors of psychopathology in BP-offspring. SUBJECTS: Fifty BP-offspring from 36 families and 25 HC-offspring from 25 families. METHODS: Psychopathology was compared in BP-offspring and HC-offspring. Factors associated with DSM-IV axis I disorders in BP-offspring were analyzed using logistic regression. RESULTS: Half of BP-offspring fulfilled the diagnostic criteria for at least one axis I disorder with attention-deficit/hyperactivity disorder (30%), anxiety disorders (14%) and affective disorders (10%) as the most frequent. After controlling for having more than one sibling in the study, the odds ratio for BP-offspring presenting an axis I disorder was 15.02 when a biological parent had bipolar disorder with a lifetime history of psychotic symptoms and 3.34 when one parent had bipolar II disorder. Moreover, a higher Global Assessment of Functioning score in the biological co-parent was associated with a significantly lower frequency of axis I disorders in BP-offspring. DISCUSSION AND CONCLUSIONS: Psychopathology in BP-offspring should be routinely assessed, with special emphasis on children from parents with specific disease characteristics (psychosis, BP II disorder) in order to establish an early diagnosis and appropriate interventions.

La terapia electroconsultiva en el tratamiento de la depresión bipolar / Electroconvulsive therapy in the treatment of bipolar depression

Desde su introducción la terapia electroconvulsiva es un tratamiento usado en los trastornos afectivos, especialmente en las fases depresivas del trastorno bipolar. El avance en su técnica lo ha convertido en una opción útil y actual tanto en el tratamiento de las fases agudas como en la prevención de las recurrencias. El objetivo de esta revisión es recoger la información disponible hasta la actualidad acerca del uso de la terapia electroconvulsiva en la depresión bipolar. Sus indicaciones, su eficacia, su predicción y su patrón de respuesta se incluyen en este trabajo, así como sus complicaciones, sus efectos adversos y sus interacciones farmacológicas. Asimismo también se recopilan las diferencias de respuesta entre la depresión bipolar y la unipolar

Since its introduction, electroconvulsive therapy is a treatment used in mood disorders, especially in the depressive phases of bipolar disorder. The advance of this technique has made it a useful and current option both in the treatment of acute phases as in the prevention of recurrences. The objective of this revision is to collect available data about the use of electroconvulsive therapy in bipolar depression. Its indications, effectiveness, prediction and patterns of response are included in this work, together with its complications, adverse events and drug interactions.
