LAMOTRIGINE-INDUCED MANICEPISODEINA PATIENT WITH COMORBID BIPOLAR DISORDER AND OBSESSIVE-COMPULSIVE DISORDER: CASE REPORT

The coexistence of obsessive-compulsive disorderand bipolar disorder is a prevalent issue in psychiatry.Population studies have found lifetime prevalence rates of comorbid obsessive-compulsive disorderin bipolar disorder patients ranging between 11.1% and 21%. The primary treatmentforobsessive-compulsive disorder, serotonin reuptake inhibitors, can induce manic episodes in bipolar disorder patients. This article presents a case of a 54-year-old woman with bipolar disorder and obsessive-compulsive disorder comorbidity, who experienced a manic shift after the introduction of lamotrigine, a drug commonly used for bipolar disorder and known for its mood-stabilizing properties. Although lamotrigine has been recommended, especially for patients predisposed to depressive bouts, its potential to induce manic or hypomanic states remains controversial. The presented patients reaction to lamotrigine suggests a possible link between the drug and the onset of manic episodes, especially in those with a history of bipolar disorder and obsessive-compulsive disorder. Furthermore, while lamotrigine offers benefits for bipolar depression, healthcare professionals need to exercise caution due to its potential to initiate manic or hypomanic states, especially in patients with complex clinical backgrounds. Comprehensive research and careful post-marketing observations are crucial to better understand the risk-benefit profile of lamotrigine.

New onset of mania in COVID-19 infection: A report of two cases

Background: Those who have infected with coronavirus disease 2019 (COVID-19), experience a range of symptoms, from mild and self-resolving respiratory illnesses to severe respiratory complications, as well as a range of the emotional symptoms of fear, guilt, anger, or anxiety due to the need of quarantine isolation. Clinical cases with a new onset of psychiatric symptoms in the acute stage or aftermath of COVID-19 have also been described in the literature. The impact of COVID-19 on psychological health across all stages of illness has become an area of interest in psychiatry. Methods: We at Johor Bahru, Malaysia, would like to report two patients without any history of any known psychiatric illness, who had their first manic episodes during the acute stage of COVID-19 infection. Results: Patient A was a 29-year-old married female patient, had a COVID-19 infection which were treated smoothly. But unfortunately, the devastating news of her husband's hospitalization for COVID-19 infection and the death of her sister-in-law due to the deadly virus came on the day of her discharge. Since she developed a picture of a manic episode with as elated mood, irritability, talkativeness, increased energy, decreased need for sleep, spending spree, reckless driving, excessive ideas concerning COVID-19 infection, and excessive sexual drive. She subsequently responded to treatment and was discharged with daily 600 mg of oral lithium carbonate, 200 mg of oral chlorpromazine, and 1,000 mg of sodium valproate Chrono. Patient B was a 31-year-old married homemaker and she presented herself to the emergency department for stage COVID-19 infection and witnessed resuscitation and eventual deaths of several patients diagnosed with COVID-19 infection. She was so frightened that she had become easily distracted, increasingly irritable, and talkative. Having reduced need for sleep at night, she would repeatedly call her friends and family around the clock to check if they had COVID-19 infection. She claimed to have the power to heal bone fractures with naked eyes. Furthermore, she started to see supernatural creatures around her at home. She subsequently responded to daily 750 mg of lithium carbonate and 1,000 mg of amisulpride during a 14-day inpatient stay. Conclusion: We content that our two patients had a new onset of manic episode after COVID-19 infection. We suggest that manic symptoms may have been triggered through an episode of COVID-19.

An Acute Manic Episode During 2019-nCoV Quarantine

BackgroundThe 2019-nCov pandemic is currently a stressor for the general public worldwide. In China, people who have a history of contact with infected or suspected individuals need to quarantine for at least 2 weeks. Many people experienced anxiety, panic and depression in the quarantine period. However, acute manic episode triggered by stressful events is not common and was neglected. Case presentationA 32-year-old woman with direct contact history with her infected colleagues showed elevated mood and increased activity when she was identified negative of nuclear acid amplification test, after experiencing extreme stress in quarantine. She was diagnosed with acute manic episode finally. The social zeitgeber and reward hypersensitivity theoretical models have attempted to use psychobiological perspectives to determine why life stress can trigger a mood episode, including (hypo)mania. Besides, the temporal correlation between her somatic symptoms and psychological stimuli indicated a possibility of functional disturbance under acute stress. ConclusionQuarantine is a major stressful event disrupting social zeitgebers for people who have had contact with infected individuals, especially for vulnerable individuals with a hypersensitive reward system. Stress could act as a trigger in the onset of manic episode, so psychological support should be more targeted at the vulnerable individuals in the initial phase of emergent crisis.

Neural Subtypes of Euthymic Bipolar I Disorder Characterized by Emotion Regulation Circuitry

BackgroundCurrent diagnostic strategy for bipolar disorders relies on symptomological classification. Yet, responses to both pharmacological and psychotherapeutic treatments vary widely, suggesting that underlying neuropathological differences are not well defined by current nosology. Classifying patients with bipolar disorder based on emotion regulation network (ERN) activation may account for some of the heterogeneity within the disorder. MethodsEuthymic participants diagnosed with bipolar I disorder (n = 86) and healthy subjects (n = 80) underwent functional magnetic resonance imaging scans while engaged in emotional reappraisal of negative stimuli. After determining average regional activations in key network regions, we applied agglomerative hierarchical clustering to identify subtypes of bipolar disorder. Next, we examined relations among neural subtypes, demographic variables, and mood symptoms. ResultsAnalyses revealed two primary neural subtypes of euthymic bipolar I disorder participants. The first subtype, ERN cluster 1, was characterized by increased amygdala activation and slightly increased ventrolateral prefrontal and subgenual cingulate activation, whereas ERN cluster 2 was defined by decreased amygdala activation with wider-spread prefrontal activation. Cluster 1 was associated with a higher number of hospitalizations for depression (odds ratio = 1.30, 95% confidence interval = 1.02–1.64) and later onset of manic episodes (odds ratio = 1.06, 95% confidence interval = 1.00–21.13) than cluster 2. ERN clusters of healthy subjects differed from bipolar disorder clusters and were defined by differential activation of the prefrontal cortex. ERN clusters of healthy subjects, which differed from bipolar disorder clusters, were defined by differential activation of the prefrontal cortex. ConclusionsEmotion regulation circuitry can distinguish neurobiological subtypes of bipolar disorder in the euthymic state. These subtypes, which are differentially associated with indices of illness severity and subsyndromal affective symptoms, may help to inform relapse risk and more personalized treatment approaches.

Is Mania Precipitated by Life Events?

Objectives To describe the prevelance of life events as precipitants of manic episodes in patients with bipolar affective disorder. Methods A descriptive cross sectional study. Fifty three inward patients with mania were selected by simple random sampling method during the study period of one month. The data was obtained through an interviewer administered questionnaire and Holmes and Rahe Stress scale. Results Thirty two (60.3%) of the study subjects were females and the mean age was 35.8 years (range 18-62). Bipolar affective disorder current episode mania with psychotic symptoms was the diagnosis in 52.8% (n=28). Thirty one patients (58.5%) had experienced life events in the month preceding the onset of manic episode. Eight (25.8%) of the life events were above 50 life change units of Holmes and Rahe Stress Scale. The most commonly occurring life events were marital separation (n=5, 16.1%), trouble with in laws (n=5, 16.1%) and change in living conditions (n=4, 12.9%). The other precipitant identified was defaulted treatment which was present in 43.3% (n=23), while 3.7% (n=2) share the combination of treatment default and life events. Conclusions This study reveals that life events have played an important role in precipitating manic episodes in patients with Bipolar Affective disorder.

Onset of Manic Episode during Chemotherapy with 5-Fluorouracil

The authors report a case of 5-Fluorouracil (5-FU) induced manic episode in an elderly female without any previous psychiatric history. The patient presented manic symptoms after 4th cycle of 5-FU chemotherapy after surgery of rectal cancer. After cessation of chemotherapy and administration of olanzapine and divalproex sodium, symptoms were subsided within 10 days.

Stress quotidien, routines et spectre bipolaire

Bipolar patients relapse more frequently under conditions of stress, even when compliant with prescribed medication. Although the biological bases of stress reactivity remain widely debated, the disruption of biological or circadian rhythms has been suggested as one possible mechanism through which stress increases the risk of episodes. This hypothesis has gained support from recent evidence demonstrating that the disruption of social rhythms is particularly implicated in the onset of manic episodes. However, it is currently unknown to what extent bipolar patients may differ from normal controls in terms of the basic prevalence and nature of daily life routines, or if such individuals are more sensitive to the disruption of such rhythms following exposure to stress. Using a dimensional perspective of bipolar disorder, 1728 French university students were first screened concerning diverse psychological and clinical characteristics. Two hundred and twelve individuals at high or low-risk for mood and substance use disorders were then invited to participate in a week-long period of ambulatory monitoring using the experience sampling method (ESM). During this phase, participants were given a preprogrammed PDA microcomputer which provided ambulatory assessments of behaviour and stress at fixed intervals (randomized across participants). At the end of the ESM phase, the microcomputers were collected and structured diagnostic interviews were administered to each participant. For the purposes of the current study, analyses focused on a subsample of 92 individuals, reflecting the 28 participants who met lifetime criteria for a manic (n=15) or hypomanic episode (n=13), and the 64 individuals who were free of any lifetime disorder. Data were analyzed using hierarchical nonlinear (Bernoulli) models for repeated measures. Covariates included age, sex, frequency of substance use and cognitive vulnerabilities assessed at screening. A Bonferroni correction was applied to adjust alpha levels within each category of activity, social interaction or environmental context. A total of 2777 valid ESM assessments were provided by the final sample concerning their behaviour and activities across diverse daily life contexts. Individuals having a lifetime history of mania or hypomania were significantly less likely than normal controls to have daily life routines relative to being at work, in class, having social contact with work colleagues or students, and to be performing personal hygiene activities. However, such individuals were more likely to be in the company of a romantic partner at the same moment each day. Time-lagged analyses demonstrated that, following conditions perceived as stressful, individuals with a history of mania or hypomania were less likely to repeat the same activities or behaviour of previous days concerning being at parents' or family's house, being at friends, and travelling or commuting, but more likely to be in a work environment, and in a bar or restaurant. The findings provide support for the notion of differences in daily life rhythms and routines among individuals with bipolar spectrum conditions, as well as the possibility of increased stress vulnerability in this population. Although a conservative analytic strategy was employed to minimize chance associations, the present findings can be considered only as preliminary and should be interpreted with caution in light of the moderate sample size, young age and non treatment-seeking nature of the sample. Future controlled investigations using ambulatory monitoring techniques are needed to pursue the investigation of these questions in treated samples.

The Importance of Routine for Preventing Recurrence in Bipolar Disorder

The Importance of Routine for Preventing Recurrence in Bipolar Disorder

Social rhythm disruption and stressful life events in the onset of bipolar and unipolar episodes.

An association between social rhythm disruption (SRD) and onset of manic episodes has recently been observed. Whether other types of bipolar (depressive and cycling) or unipolar depressive episodes are similarly related to SRD is unclear, as is the association between severely threatening life events and onset of bipolar manic, depressed and cycling episodes. Bipolar patients with purely manic (N= 21), purely depressed (N = 21) and cycling (N = 24) episodes, and 44 patients with recurrent unipolar depression, were interviewed with the Bedford College Life Events and Difficulties Schedule. The presence of severe and SRD events during the year prior to index episode onset was then determined. More manic than cycling and unipolar subjects experienced SRD events during 8- and 20-week pre-onset periods, and severe events during 20-week pre-onset periods. Controlling for age and prior number of episodes left most findings unchanged. An earlier finding of more manic subjects with SRD events in an 8-week pre-onset versus control period was also replicated. It appears that manic onsets are influenced by stressful life events, especially those involving SRD, in a unique manner compared to onsets of other types of bipolar and unipolar episodes. Onset of bipolar cycling episodes, in contrast, seems to be relatively unaffected by SRD or severe life events. These findings refine the hypothesis that SRD may precipitate onset of affective episodes to be specific to manic onsets.
