Characterizing MyMood Patterns of Use

Bipolar DisorderMood Disorders2 more

MyMood is an electronic mood-charting tool available to the general population of Sunnybrook Health Sciences Centre (SHSC). This project aims to characterize duration and frequency of use of MyMood by users characteristics and determine if there is any significant variability in duration and frequency of use attributable to users' age, sex, self-reported diagnosis of a mood disorder, and/or prior treatment.

A Comprehensive Assessment and Follow up Descriptive Study on Bipolar Disorder

Bipolar DisorderUnipolar Disorder

The purpose of this study was to investigate the reliability and validity of the bipolar index (BPX) to diagnosis bipolar disorder, and to verify the stability of it in identifying bipolar disorder; the secondary purpose was to understand the dynamic changes of bipolar disorder in natural status.

Medibio Depression Monitoring Study

DepressionBipolar3 more

An objective measure of treatment response could be a valuable new tool in the armamentarium of depression management, and this holds true for stimulation-based and pharmacological therapies alike. Hence, the Medibio Depression Monitoring Study will use the Medibio analytics platform to characterize autonomic, circadian, and sleep patterns before and during the initial 8 weeks of pharmacologic therapy for moderate-to-severe depression. The study will also explore any differences in these measures between treatment responders and non-responders, and between depression subtypes, including bipolar and unipolar depression. The study will also characterize longitudinal, ambulatory EEG measures throughout the observation period.

Influence Factors and Cognitive Characteristics in Unipolar and Bipolar Depression:Based on the...

Cognitive Impairments

Cognitive impairment is the core symptom of unipolar and bipolar depression, which seriously affects the prognosis of the disease and the rehabilitation of social function. There is no unified conclusion in the field and severity of cognitive impairment, and the cause of cognitive impairment is unknown, which may be related to many factors. In this study,the THINC-it tool was used to study the characteristics of cognitive impairment in unipolar and bipolar depression by longitudinal follow-up, which provides a theoretical basis for the differential diagnosis of unipolar and bipolar depression. Early identification and intervention of risk factors can improve the prognosis of the disease.

Antidepressant Treatments and Cognitive Function of Bipolar Patients

Bipolar DisorderCognition

Patients with bipolar disorder (BD) have a wide range of neurocognitive dysfunction, which lead to impaired psychosocial function and reduced quality of life. Therefore, improving neurocognitive function has become an important goal of BD treatment. Aiming at this, some clinical studies have been performed but failed to illustrate significant positive efficacies of pharmacological therapy or non-pharmacological therapy, which could attribute in part to insufficient understanding on the risk factors that affect the neurocognitive function of BD patients. Delayed diagnosis of BD is so common that a lot of patients receive long-term antidepressant treatment before of diagnosis of unipolar depression. There is controversy about whether antidepressant treatment in early stage would affect the neurocognitive function of BD patients. In view of the high prevalence of delayed diagnosis and the use of antidepressants, it is of great scientific significance and clinical value to clarify this matter and other factors that may potentially affect the neurocognitive function of BD patients.

Racing and Crowded Thoughts in Mood Disorders

Bipolar Disorder

Racing thoughts relate to subjective acceleration of thinking which has been essentially associated with manic episodes in bipolar disorder. Qualitatively, the phenomenology of racing thoughts in major depression seems to differ from rumination and pure manic racing thoughts: thoughts of all kinds accumulate in the patient's head. Recent qualitative evidence is consistent with the existence of these two kinds of "thought overactivity" related to mood disorders. In order to evaluate this and better understand the psychopathological and cognitive mechanisms that underlie thought overactivity in mood disorders, we have created a 34-item self-questionnaire - the Racing and Crowded Thoughts Questionnaire (RCTQ) and a number of neuropsychological tasks (time perception, cognitive flexibility). Also, given the relationship between mood disorders and creativity, it is likely that thought overactivity is related to increased creativity. We aim at evaluating this relationship through the French version of the Cognitive Processes Associated with Creativity scale (CPAC).

Bipolar Disorder

Genetic transition is important in the etiology of bipolar disorder (BD). So, evaluation of children of BD parents and diagnosed with and BD children whether or not brain has affected zones. These groups were compared to healthy controls and whether or not the mental health of children is influenced will be evaluated by the clinical investigation.

The Antiatherogenic Properties of HDL in Psychiatric Patients With and Without Antipsychotic Therapy...

SchizophreniaSchizoaffective Disorder1 more

Background: Among individuals with schizophrenia, there is an increased prevalence of obesity, dyslipidemia ,diabetes mellitus and related conditions such as cardiovascular disease. People with severe mental illnesses, such as schizophrenia, depression or bipolar disorder, have worse physical health and reduced life expectancy compared to the general population. Number of epidemiological studies of patients with schizophrenia have documented a higher incidence of cardiovascular disease than in the general population, and patients with schizophrenia may be at an elevated risk for cardiovascular disease even in the absence of antipsychotic treatment. Affinity for the H1 receptor is most closely linked to increased weight gain, although affinity for D2, 5-HT1A, 5-HT2C and a2-receptors may also be involved. Drug affinity for the H1, M3 and 5-HT2C receptors is correlated with an increased risk of diabetes. High-density lipoprotein cholesterol (HDL-C) concentration in the blood is independently and inversely associated with an increased risk of cardiovascular disease(CVD). However many patients with 'normal' or even 'elevated' plasma HDL experience clinical events. HDL may not always be atheroprotective and in some conditions, it paradoxically enhances the process of atherosclerosis. In addition to its role in reverse cholesterol transport, HDL shows many other protective properties towards atherosclerosis. HDL inhibits the chemotaxis of monocytes , prevents endothelial dysfunction and apoptosis, prohibit slow-density lipoprotein (LDL ) oxidation, and stimulates the proliferation of endothelial cells and smooth muscle cells. These anti-inflammatory, antioxidative, antiaggregatory, anti-coagulant, and pro-fibrinolytic activities are exerted by different components of HDL Aim of the study: To investigate the functional properties of HDL in psychiatric patients before and during antipsychotic therapy. Patients and methods: The blood will be drawn at baseline before the initiation of antipsychotic drugs and 2 months under the antipsychotic treatment. Study procedures: Full lipid profile including triglycerides, LDL-C, Total cholesterol, HDL-cholesterol, apo AI, apoAII and apoB100. Serum Paraoxanase Activity LDL oxidation and resistance to oxidation (measured by conjugated diens formation during incubation in the presence of copper). HDL composition: total and unesterified cholesterol, triglycerides and phospholipids, TBARS content before and after exposure to AAPH as a major indicator of oxidative stress, PON activity using phenylacetate as a substrate, apoA1and PAF. Serum parameters e.g. Diacyl glycerol acyltransferase activity, free ApoA1 and LCAT activity. 3 [H]-Cholesterol efflux will be measured by incubating J744 macrophages with serum. Radioactivity will measured by β counter in the cell lysate and the medium. Statistical methods: One-way AVOVA and Student's t-test for paired samples will be used for comparison of multiple groups and paired samples, respectively. p<0.05 will be considered significant.
