Adherence to Mood Stabilizers Using a Pharmacy Prescription Database Analysis: Assessment of the Relationship of Non-Adherence to Hospitalization Rates, Cost of Care, and Gender for Patients with Bipolar Type I DisorderKale, Andrea, Kuchanskaya, Yuliya January 2006 (has links)
Class of 2009 Abstract / Objectives: This study utilized a prescription claims database to retrospectively assess the relationship between adherence rates with a mood stabilizer in bipolar type I patients for: gender, age, psychiatric hospitalization rates, cost of services, and concomitant psychotropic medications.
Methods: Adult patients with bipolar type I disorder (N=149; F=92 and M=57) who received at least two prescriptions of a mood stabilizer (i.e., carbamazepine, lamotrigine, lithium, oxcarbazepine, and valproic acid) during a 3-month intake period were included. Adherence to the mood stabilizer was retrospectively analyzed using high: >75% (> 274 days) vs. low: < 75% (< 274 days) supply of a mood stabilizer during 12-months.
Results: Only 35.6% of the patients (N=53) met the criteria for > 75% adherence and 11.4% (N=17) met the criteria for > 90% adherence. There was a trend toward women having more days supply of a mood stabilizer compared to men (p=0.08) and older patients having a higher adherence rate with a mood stabilizer (p=0.06). The high adherence group had greater prescription costs (p<0.001) and total cost per year (R2=0.34, p=0.064) and more concomitant medications (p=0.04) than the low adherence group. Overall, there were no significant differences between the high and low adherence groups for mean hospital days, inpatient costs, and total cost of care. Among those patients that were hospitalized there was a negative correlation between adherence and inpatient cost (R2=0.49, p=0.024). Conclusions: Our findings suggest that patients with bipolar type I disorder demonstrate poor medication adherence with a mood stabilizer and that adherence rates based on a prescription claims database using two adherence categories may not be a predictive factor for psychiatric hospitalizations or cost of care.

Bipolar Disorder in the Family: Impact on Functioning and Adjustment to CollegeCrandall, Erin 08 1900 (has links)
Bipolar disorder is a serious mental disorder, affecting anywhere from 2 to 4 percent of Americans. Though research has indicated that this disorder can be devastating for patients, less is known about how the disorder impacts family members. There is no research that has considered impacts on family members adjusting to college. The purpose of the current study was to determine the extent to which having a family member with bipolar disorder impacts adjustment to college, as well as factors that might account for worse functioning. Two groups were recruited: students with a bipolar family member (n = 25) and students with no family history of the disorder (n = 50). Participants were interviewed regarding their own histories of a mood disorder, as well as mood disorder histories in their immediate families. They then completed surveys assessing adjustment to college, functioning, caregiving burden, parental relationship, and attachment style. Students with a family history of bipolar disorder had significantly lower social adjustment scores, lower personal-emotional adjustment scores, and lower financial functioning scores than students without this history. Lower scores were found even after controlling for psychopathology. Avoidant attachment behaviors, anxious attachment behaviors, and aspects of the paternal relationship were identified as potential mediators. Caregiving burden was identified as a partial mediator. Implications for families and educational institutions are discussed.

Community-Based Care for Youths With Early and Very-Early Onset Bipolar I DisorderJerrell, Jeanette M., Shugart, Margaret A. 01 August 2004 (has links)
Objective: Phenomenological and treatment differences between children and adolescents with bipolar I disorder in a public mental health system were examined. Method: A systematic medical record review was performed on a sample of 83 patients, focusing on documented DSM IV symptoms of mania or depression, attention deficit hyperactivity disorder, conduct disorder, schizophrenia, and post-traumatic stress disorder. Cross-tabulation and logistic regression analyses were performed comparing the presence/absence of symptoms for each disorder and treatments provided for children and adolescents. Results: Prepubertal patients were significantly more likely to be male, easily distracted, inattentive, detached from others, hyper-vigilant, prescribed stimulant medication, and to meet the diagnostic criteria for attention-deficit/hyperactivity disorder or Conduct Disorder than adolescents. Conclusions: Consistent with the published literature, phenomenological differences between children and adolescents are present and being recognized for differential diagnosis and treatment by community practitioners. More attention to documenting some cardinal symptoms of mania, the persistence of bipolar symptoms, and the nature of cycling for those with mixed states is needed.

Learning to ExhaleMojapelo, Lebohang January 2019 (has links)
Magister Artium - MA / My MA mini-thesis in Creative Writing is a collection of 33 poems titled Learning to Exhale. The
poems are centred around a character – a black African woman who is sharing her experiences
of mental illness. The poems revolve around memory, forgetting and remembering; going back
to the moment when the woman realises that she is ill, understanding it from the present while
working to find ways to express what bipolar disorder is and how she experiences it. The
collection also highlights her search for words and meaning to describe these experiences that
are highly traumatic. This is to create a language of expressing the indescribable. This means that
the form and structure is experimental, combining differing styles and form to show different
voices, different states of mind that swing from depression, mania to suicidal thoughts.

Attitudes and Perceptions Among African Americans About Dating Individuals with Bipolar DisorderJohnson, Casey Michelle 01 January 2019 (has links)
Individuals who experience bipolar disorder may have difficulty acquiring and maintaining relationships due to the stigma associated with mental illness. The purpose of this generic qualitative study was to examine the attitudes and perceptions of African American men and women regarding their experiences of dating and relationships with individuals who suffer from bipolar disorder. The theory used in this study was equity theory. The research question for this study explored how African American adults experience relationship acquisition and maintenance with a partner who has been diagnosed with bipolar disorder. For this generic qualitative study, there were 12 respondents. Participants were African American adults who had dated or been in a relationship with an individual diagnosed with bipolar disorder. Themes that emerged from this study were sense of relief, sense of fear, unmodified affection, benefits of the relationship, resolution of unfair situations, reluctance to participate in a relationship with an individual diagnosed with bipolar disorder again, and race intensified the relationship. The participants associated acquisition, or the early stages of the relationship, with challenges, especially if they were unaware of the diagnosis in the beginning and could not explain certain behaviors. The results of this study can be used to promote understanding about bipolar disorder and the impact of mental illness on relationships.

Developmental Dynamics of the Human Brain TranscriptomeArbabi, Keon January 2021 (has links)
Large-scale transcriptomic studies are among of the most comprehensive accounts we have of the biological processes underlying human brain development and ageing. However, many analyses and descriptive models applied to gene expression data implicitly assume that developmental change is continuous and uninterrupted. Perhaps this bias is often overlooked because the emphasis is on what is changing during development rather than how development itself is changing. Indeed, despite the richness of transcriptomic data and its capacity to recapitulate higher-order functions, few have used it to understand the dynamics of brain development. Gene expression is determined by complex, high-dimensional interactions of the gene regulatory network. Dynamic systems theory states that the interactions of components in any complex systems will converge on certain stable patterns, also known as attractor states. To approximate these stable states, the current study leveraged robust and sparse k-means clustering to identify tissue samples with similar patterns of gene expression across the transcriptome. Sample ages were then used to visualize when in developmental time these stable patterns are present. The resulting model describes the developmental dynamics of the brain transcriptome as a series of non-linear, overlapping states that progress across the lifespan. / Thesis / Master of Science (MSc)

RELATIONSHIP BETWEEN OXIDATIVE STRESS AND COMBINED ORAL CONTRACEPTIVE USE IN WOMEN WITH BIPOLAR DISORDERLenchyshyn, Jessica 17 November 2014 (has links)
Background: The objective of this thesis was to measure oxidative stress (OS) in women with Bipolar Disorder (BD) who used combined oral contraceptives (OCU). Based on our literature review, it was predicted that OCU would increase OS levels relative to non-contraceptive users (NCU) in women. Methods: Thirty-five participants (BD n=25; Control n=10) were recruited from an ongoing study based in British Columbia ‘The Systematic Treatment Optimization Program in Early Mania.’ Participants were administered psychological screening tools (Young Mania Rating Scale (YMRS), Montgomery-Åsberg Depression Rating Scale, Mini International Neuropsychiatric Interview and Hamilton Depression Rating Scale) and provided a blood sample for the assays (Lipid Hydroperoxide (LPH), Protein Carbonylation, 4-Hydroxynonenal, 3-Nitrotyrosine (3-NT) and 17-Beta Estradiol). Results: In our primary analysis we did not find differences in OS between BD and controls relative to OCU. Within our remaining analyses, only BD women (n=17) and who gave smoking status were included. We found 3-NT to be increased in OCU compared to NCU (F (1, 12) = 5.639, p = 0.035). With respect to mood stabilizer use, 3-NT was increased in OCU relative to NCU (F (1, 10) = 6.33, p=0.031). As for atypical antipsychotics, 3-NT was heightened in OCU adjunctive users compared to NCU who did not use atypical antipsychotics (F (3, 10) = 4.822, p = 0.025). As for our correlation analyses, YRMS correlated with 3-NT and LPH in OCU BD women (r(11)= 0.711, p=0.014 and r(11) = 0.676, p=0.022, respectively) and 17-Beta Estradiol correlated with LPH (r(17) = 0.598, p = 0.001). Our results are preliminary and are limited by our small sample size and various other factors (i.e. controls). Conclusion: The association between hormones and oxidative stress still remains controversial. Here we showed, after controlling for smoking, BMI and age the use of a COC significantly increased 3-NT in women with BD. Moreover, hormones may influence the relationship between OS and mood episodes. / Thesis / Master of Science (MSc)

Intracortical myelin in bipolar disorder type I and the impacts of neuregulin-1 variation and ageKidd, Katrina January 2023 (has links)
Introduction: Bipolar disorder is associated with cortical abnormalities, including deficits in intracortical myelination. Intracortical myelin follows an inverted-U trajectory over the lifetime, but this trajectory is blunted in individuals with bipolar disorder. Little is understood about which genetic factors contribute to these deficits. Neuregulin-1, a cell-signalling protein, has been shown to contribute to cortical abnormalities and increase susceptibility to related disorders. Assessing the prevalence of neuregulin-1 polymorphisms, notably rs6994992, in bipolar disorder may elucidate the genetic contributors of intracortical myelin deficits and increase our understanding of factors causing susceptibility to bipolar disorder.
Methods: 67 participants with bipolar disorder type I and 75 healthy control participants were included. T1-weighted MRI images were collected and processed to create R1 cortical maps, a proxy measure of intracortical myelin. Participant blood samples were genotyped at the rs6994992 locus. Linear models were used to test whether intracortical myelin can be predicted by age, bipolar diagnosis and NRG1 genotype.
Results: Intracortical myelin is significantly predicted by age, diagnosis and genotype together in the motor cortex (left: R2 = 0.09, p < 0.01, right: R2 = 0.06, p < 0.05), the right premotor cortex (R2 = 0.095, p < 0.001), and the right inferior frontal cortex (R2 = 0.098, p < 0.001). Age is a significant individual predictor of intracortical myelin in the right dorsal anterior cingulate cortex, the bilateral motor cortex, the right premotor cortex, and the right inferior frontal cortex.
Conclusions and Future Directions: Our study suggests that the right premotor, bilateral primary motor, and right inferior frontal cortices are regions of interest for understanding how intracortical myelin changes throughout the lifetime, especially in bipolar disorder. Future work should examine the impact of polygenic risk scores of bipolar disorder on intracortical myelin. / Thesis / Master of Science (MSc) / Bipolar disorder is associated with neurobiological changes, including cortical abnormalities, contributing to a greater disorder burden. Cortical myelination changes throughout the lifetime and larger deficits are found in individuals with bipolar disorder. However, the role of genetics in these intracortical myelin deficits is largely unknown. This thesis investigates how intracortical myelin content in various regions of the cortex is impacted by age, bipolar disorder diagnosis, and neuregulin gene variants. The goal of this research is to contribute to a better understanding of how genetics and age impact intracortical myelin in bipolar disorder to better understand the neurobiological changes of the disorder.
