Recurrent Major Depressive Disorder

BackgroundWhite matter (WM) impairments have been reported in patients with bipolar disorder (BD) and those at high familial risk of developing BD. However, the distribution of these impairments has not been well characterized. Few studies have examined WM integrity in young people early in the course of illness and in individuals at familial risk who have not yet passed the peak age of onset.MethodWM integrity was examined in 63 BD subjects, 150 high-risk (HR) individuals and 111 participants with no family history of mental illness (CON). All subjects were aged 12 to 30 years.ResultsThis young BD group had significantly lower fractional anisotropy within the genu of the corpus callosum (CC) compared with the CON and HR groups. Moreover, the abnormality in the genu of the CC was also present in HR participants with recurrent major depressive disorder (MDD) (n = 16) compared with CON participants.ConclusionsOur findings provide important validation of interhemispheric abnormalities in BD patients. The novel finding in HR subjects with recurrent MDD – a group at particular risk of future hypo/manic episodes – suggests that this may potentially represent a trait marker for BD, though this will need to be confirmed in longitudinal follow-up studies.

Although there is a broad base of literature on depression among elderly patients and on mania in younger patients, there is a relative paucity of information on bipolar disorder in the elderly population. While the quantities of data reflect the relative prevalences of these illnesses, there is evidence to suggest that classification of mania in the elderly with respect to age of onset, natural course, family history, and pathophysiology may be useful in understanding the heterogeneous etiologies of this syndrome. This paper presents a review of the literature on the incidence and course of illness in late-life bipolar disorder. Further, dilemmas of diagnostic classification in relation to associated risk factors will be discussed.

The diagnosis and treatment of bipolar disorders (BPD) in children is currently one of the biggest challenges and area of controversy in the field of child psychiatry. Bipolar disorders encompass several affective disorders that involve alterations in the degree of activity, content and form of thinking that are characterized by biphasic episodes of mood. This group of disorders affect approximately 1% of the world population and begin in youth (the average age of onset of ~20 years). However, in some studies a delay of 5 years has been observed since the presentation of symptoms at the beginning of the treatment. Currently, the diagnosis of TBP in children and adolescents should be based on the same set of symptoms applied to adults, as well as the general principles of the treatment. The research carried out around this disorder has resulted in changes in the conceptualization and approach of this pathology, now conceived as a group of disorders that share changes in mood and other cardinal symptoms, of a chronic and progressive nature that impacts in a negative way in those who suffer them.

Long Term Follow Up

Behcet disease is rare in children. There are only two reports of Behcet disease in childhood, describing seven patients. Three pediatric patients are described, in whom the age of onset ranged from 6 to 11 years. Aphthous stomatitis and arthritis were present in all of the patients; genital ulcers, iridocylitis, erythema nodosum, and CNS involvement were present in two patients. Other manifestations included Stevens-Johnson-like eruption, fever of unknown origin, and testicular involvement. All of the patients responded to glucocorticoids; two were also treated with colchicine and one was treated with chlorambucil. In two patients, follow-up of more than 10 years was done, with complete cure in one patient and benign course of illness in the other. Because of the rarity of the disease in childhood and the difficulty in making the diagnosis, there is not enough awareness by pediatricians concerning this disease.

Course Of Illness

Thirty-eight elderly patients with primary depressive illness (Feighner criteria) were followed up for 7–31 months. In the absence of persistent organic signs and severe physical illness, age of onset (first depressive episode after 60) but not age was significantly related to course of illness. Compared to early onset depressives, late onset depressives were more likely to remain completely well during the follow-up period and less likely to have frequent or disabling relapses.

IntroductionAge of onset of illness may be useful in explaining the heterogeneity among older bipolar patients.ObjectiveTo examine the relationship of age of onset with clinical, demographic and behavioral variables, in older patients with bipolar disorder.MethodsThis was a cross-sectional, descriptive and analytical study, including 24 patients suffering from bipolar disorders, aged 65 years or more and followed-up in outpatient psychiatry unit at Hedi Chaker university hospital in Sfax in Tunisia. We used a standardized questionnaire including socio-demographic, behavioral and clinical data. Age of onset was split at age 40 years into early-onset (< 40 years; n = 12) and late-onset (≥ 40 years; n = 12) groups.ResultsThe mean age for the entire sample was 68.95 years. The mean age of onset was 39.95 years. The majority (60%) of patients were diagnosed with bipolar I. Few meaningful differences emerged between early-onset and late-onset groups, except that tobacco use was significantly higher in the late-onset group (66.6% vs. 16.6%; P = 0.027). No significant differences between the early-onset and late-onset groups were seen on demographic variables, family history and number of medical diagnoses or presence of psychotic features.ConclusionOur study found few meaningful behavioral differences between early versus late age at onset in older adults with bipolar disorder.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Distinct Grouping

Discriminant and canonical variate analyses were performed using 302 patients, on whom ratings of lifetime psychopathology and course of illness had been made. DSM–III diagnoses were used to form the criterion groups. Bipolar disorder emerged as a distinct grouping, but there are reasons for dissatisfaction with its definition. The remaining patients formed a ‘schizodepressive continuum’, but this also had a tendency to bimodality. It is possible that the distinction between schizophrenia and depression was obscured by inadequacies in the data and the inclusion of excessive numbers of patients with schizoaffective depression in this study.

It appears that bipolar patients suffer from cognitive difficulties whereas they are in period of thymic stability. These intercritical cognitive difficulties are fairly stable and their severity is correlated with the functional outcome of patients. Nevertheless, the profile of cognitive impairment varies significantly from study to study quantitatively and qualitatively. According to the studies, the authors find difficulties in terms of learning, verbal memory, visual memory, working memory, sustained attention, speed of information processing, functions executive. On the other hand, deficits of general intelligence, motor functions, selective attention, and language are not usually found. One of the reasons for the heterogeneity of results is the difficulty of exploring cognition in bipolar disorder. Many factors must be taken into account, such as the presence of residual mood symptoms, the longitudinal history of the disorder (age of onset, number of episodes due, among others, the neurotoxic impact of depressive episodes and deleterious cognitive effects). (length of hospitalization), level of disability severity, comorbidities (particularly addictive).

Objective. Several studies with contradictory results from different cultures about association of methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism in schizophrenia and bipolar disorders. Little is known about this association in Arab culture and Egypt. So the present study aimed to assess the association of MTHFR C677T polymorphism in bipolar disorder (BD) and schizophrenia in comparison to control group. The association between MTHFR C677T polymorphism and the age at onset in schizophrenia or BD was also studied.Methods. Polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) were used to examine the genotype and allele frequencies of MTHFR C677T polymorphism in 149 healthy subjects and 134 bipolar and 103 schizophrenia patients.Results. In BD and schizophrenia, there was a higher prevalence of MTHFR C677T polymorphism than healthy subjects. Earlier age at onset was found in patients with BD, carrying one copy of the T allele or CT genotypes but not in patients with schizophrenia.Conclusion. The present findings suggest that the MTHFR C677T polymorphisms are likely to be associated with the risk of developing BD and schizophrenia and influence the age at onset of BD but not the age at onset of schizophrenia.
