Gray and white matter trajectories in patients with bipolar disorder.

Objectives: Findings on brain structural abnormalities in patients with bipolar disorder (BP) are inconsistent and little is known about age-related evolution of these changes. We employed a cross-sectional, case-control study to compare structural age-related brain trajectories in patients with BP and healthy control subjects (HC) over a period of approximately 50 years. The primary aim was to understand whether white (WM) and gray matter (GM) abnormalities are present from the beginning of the illness and how they change over time.

Treatment-resistant, five-year long, postpartum-onset Capgras episode resolving after electroconvulsive therapy.

Postpartum psychosis, which rarely presents with Capgras syndrome (delusional misidentification), requires rapid symptom resolution. First-line drugs have important drawbacks, such as delayed onset of clinical response and secretion in breast milk. In this report, we report successful treatment of a treatment-resistant woman presenting with treatment-resistant Capgras syndrome, with onset during postpartum.

Mitochondrial myopathy and comorbid major depressive disorder: effectiveness of dTMS on gait and mood symptoms.

Background: Mitochondrial myopathies (MMs) often present with leukoencephalopathy and psychiatric symptoms, which do not respond to or worsen with psychiatric drugs.

Case Report: A 67-year-old woman with a 10-year history of probable chronic progressive external ophthalmoplegia, an MM, had drug-resistant, anxious-depressive symptoms. Since she had never had seizures, we proposed 20 sessions of deep transcranial magnetic stimulation (dTMS) for her depression.

Childhood traumatic experiences of patients with bipolar disorder type I and type II.

Background: Childhood trauma is an important environmental stressor associated with bipolar disorders (BD). It is still not clear if it is differently distributed between BD I and BD II. Therefore, the aim of this research was to investigate the distribution patterns of childhood trauma in BD I and BD II.

Sociodemographic, neuropsychiatric and cognitive characteristics of pathological gambling and impulse control disorders NOS in Parkinson's disease.

Despite of previous evidence supporting the association between impulse control disorder (ICD) and several demographic, clinical and therapeutic features in Parkinson's disease (PD), the relationships between pathological gambling (PG) or other variants of ICD (ICD-NOS) and specific neuropsychiatric or cognitive domains are not entirely defined. In this study, 155 PD patients without dementia or cognitive impairment underwent: i. the ICD diagnoses, using the Questionnaire for Impulsive-Compulsive Disorders, ii.

Mixed depression: clinical features and predictors of its onset associated with antidepressant use.

Background: Mixed depression (MxD) is narrowly defined in the DSM-IV and somewhat broader in the DSM-5, although both exclude psychomotor agitation as a diagnostic criterion. This article proposes a clinical description for defining MxD, which emphasizes psychomotor excitation.

Methods: Two hundred and nineteen consecutive outpatients were diagnosed with an MxD episode using criteria proposed by Koukopoulos et al.

Low-dose acetazolamide in the treatment of premenstrual dysphoric disorder: a case series.

The treatment of premenstrual dysphoric disorder (PMDD) is far from satisfactory, as there is a high proportion of patients who do not respond to conventional treatment. The antidiuretic sulfonamide, acetazolamide, inhibits carbonic anhydrase and potentiates GABAergic transmission; the latter is putatively involved in PMDD. We therefore tried acetazolamide in a series of women with intractable PMDD.

Time dysperception perspective for acquired brain injury.

Distortions of time perception are presented by a number of neuropsychiatric illnesses. Here we survey timing abilities in clinical populations with focal lesions in key brain structures recently implicated in human studies of timing. We also review timing performance in amnesic and traumatic brain injured patients in order to identify the nature of specific timing disorders in different brain damaged populations.

Neurodevelopment in schizophrenia: the role of the wnt pathways.

Objectives: To review the role of Wnt pathways in the neurodevelopment of schizophrenia.

Methods: SYSTEMATIC PUBMED SEARCH, USING AS KEYWORDS ALL THE TERMS RELATED TO THE WNT PATHWAYS AND CROSSING THEM WITH EACH OF THE FOLLOWING AREAS: normal neurodevelopment and physiology, neurodevelopmental theory of schizophrenia, schizophrenia, and antipsychotic drug action.

Results: Neurodevelopmental, behavioural, genetic, and psychopharmacological data point to the possible involvement of Wnt systems, especially the canonical pathway, in the pathophysiology of schizophrenia and in the mechanism of antipsychotic drug action.

[Olanzapine in manic/mixed patients with or without substance abuse].

Aim: To evaluate the efficacy of olanzapine in patients in their manic/mixed phase with or without comorbidity with substance abuse/dependence disorder.

Methods: In this observational, controlled, prospective study, 60 patients with a DSM-IV-TR diagnosis of bipolar disorder, manic/mixed episode (30 patients with and 30 patient without comorbidity with a substance abuse/dependence disorder) were treated with olanzapine, evaluated at discharge, and followed-up for 8 weeks. Efficacy of olanzapine was assessed by comparing the proportion of responders (an at least 50% drop in Young Mania Rating Scale [YMRS] score from baseline) and remitters (YMRS ≤ 12 and Hamilton Depression Rating Scale [HAM-D] ≤ 8) in both groups.

Citalopram-associated gambling: a case report.

Pathological gambling behaviour is a side effect of dopaminergic drugs used in Parkinson's disease, but has seldom been reported with selective serotonin reuptake inhibitors. A 58-years-old woman with somatisation disorder since the age of 20 and recent-onset major depression (at 54 years) received 40 mg/day intravenous citalopram, thereafter switching to the same dose of oral citalopram to treat her comorbid psychiatric disorders after showing poor response to paroxetine for one year. Her anxious and depressive symptoms were moderately reduced after 7 months of oral citalopram, but simultaneously, the patient admitted gambling.
