coffee bipolar disorder

BACKGROUND: Caffeine exposure modifies the turnover of monoamine neurotransmitters, which play a role in several neuropsychiatric disorders. We conducted a Mendelian randomization study to investigate whether higher plasma caffeine levels are causally associated with the risk of anorexia nervosa, bipolar disorder, major depressive disorder (MDD), and schizophrenia. METHODS: Summary-level data on the neuropsychiatric disorders were obtained from large-scale genome-wide association studies (GWASs) of European ancestry participants (n = 72,517 to 807,553) and meta-analyzed with the corresponding data from the FinnGen study (n = 356,077)...

INTRODUCTION: Alcohol, tobacco and coffee are commonly used substances and use in adolescence has previously been linked to mood disorders. However, few large prospective studies have investigated adolescent use in relation to mental health outcomes in adulthood. The main aim of this study was to examine the prospective associations between alcohol use, cigarette smoking and coffee consumption at age 16 and subsequent mood disorders up to 33 years of age. METHODS: Data from The Northern Finland Birth Cohort 1986 Study were used and a total of 7660 participants (49...

BACKGROUND: Numerous systematic reviews (SRs) and meta-analyses on non-genetic risk factors for Parkinson's disease (PD) development have been published with inconsistent conclusions. OBJECTIVE: This overview of SRs aimed to summarize evidence on non-genetic factors for the development of PD from the published SRs, and explore the reasons behind the conflicting results. METHODS: Three international databases were searched for SRs with meta-analyses summarized evidence on non-genetic factors for PD development...

INTRODUCTION: The offspring of bipolar parents (BO) is a high-risk population for inheriting the bipolar disorder (BD) and other early clinical manifestations, such as sleep disturbances. OBJECTIVE: To compare the presence of psychiatric disorders and sleep disturbances of BO versus offspring of control parents (OCP). METHODS: A cross-sectional analytical study was conducted that compared BO versus OCP. The participants were assessed using valid tools to determine the presence of psychiatric symptoms or disorders...

OBJECTIVES: In healthy populations, caffeine appears to have beneficial effects on health; however, patients with bipolar disorder (BD) are routinely advised to limit caffeine use in psychoeducation programmes. We aimed to examine all literature reporting whether caffeine intake/withdrawal impacts the natural course of BD, in terms of clinical outcomes. METHODS: PubMed, Embase and PsycINFO were searched (up to 17/07/2020) and all studies reporting data on individuals with BD comparing a measure of caffeine use with illness severity (symptoms of mania, depression, psychosis, anxiety, sleep or suicidality) were included...

Individuals with bipolar disorder (BD) have higher than average rates of coffee, tobacco and alcohol use. These substances may have deleterious effects on sleep quality and quantity, which may destabilize sleep/wake cycles and negatively impact the clinical course and prognosis of BD. The use of these substances may also be perceived as a self-medication attempt, for example, to induce sleep or to increase vigilance during the day. The objective of the current study was to investigate associations between the self-reported daily use of coffee, tobacco, and alcohol, and objective measures of sleep and activity patterns in adult individuals with BD...

OBJECTIVES: To characterise the people retrieved by the Royal Flying Doctor Service (RFDS) for treatment of mental and behavioural disorders, and to assess mental health care provision in rural and remote areas. DESIGN: Prospective review of routinely collected RFDS and Health Direct data. SETTING, PARTICIPANTS: RFDS aeromedical retrievals of patients from anywhere in Australia except Tasmania during 1 July 2014 - 30 June 2017 for the treatment of mental or behavioural disorders...

Lithium (Li) is a chemical element used for treating and preventing bipolar disorder (BD) and exerts positive effects such as anti-inflammatory effects as well as undesirable side effects. These effects of Li can be influenced by interaction with some nutritional elements. Therefore, we investigated the potential effects of xanthine (caffeine and theobromine) and catechin molecules present in some food beverages broadly consumed worldwide, such as coffee and tea, on Li-induced anti-inflammatory effects. In the present study, we concomitantly exposed RAW 264...

Background • This case illustrates the relationship between gut, hormonal, and brain function in that dietary change, mindfulness interventions, and detoxification led to resolution of disabling luteally exacerbated psychiatric symptoms. Summary • A 45-y-old, married, Caucasian female with a history of diagnosed bipolar disorder with psychotic features, premenstrual dysphoric disorder, panic disorder, and repeated occurrence of suicide attempts and self-mutilating behavior presented for outpatient management...

OBJECTIVE: The aim of this study was to examine the impact of excessive caffeine consumption on therapeutic outcomes in bipolar disorder. METHODS AND RESULTS: We report on a case of a patient with bipolar disorder whose psychiatric symptoms were ameliorated with the elevation of lithium concentrations after the reduction of excessive daily coffee consumption, and we review the relevant literatures. CONCLUSIONS: Excessive coffee consumption may exacerbate the therapeutic course of bipolar disorder through its effects on the mechanisms underlying bipolar disorder itself, as well as by affecting the blood concentration of lithium...

OBJECTIVES: Individuals with bipolar disorder (BP) are often misdiagnosed with major depressive disorder (MDD). In this study, we developed a Chinese version of 15-point hypomania scale (HCL-15) in order to determine its sensitivity and specificity in the diagnosis of BP and BP-II in particular. METHODS: A total of 623 individuals suffering a major depressive episode (MDE) were systematically interviewed with both Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Patient Edition, and HCL-15...

BACKGROUND: Across all ages and cultures, mankind has always used substances in order to induce pleasurable sensations or desirable psychophysical states. These substances, notably caffeine, tobacco, alcohol and chocolate, can be labeled 'social drugs'. METHODS: We analyzed the social drug habits of 562 patients suffering from mood disorders, according to DSM-IV-R criteria (major depressive episode, recurrent depression, bipolar type I and II disorders and depression not otherwise specified)...

OBJECTIVE: Abuse of illicit drugs and alcohol is prevalent in bipolar disorder (BPD) patients, and is an adverse prognostic factor. Much less is known about correlates of nicotine and caffeine consumption, but tobacco smoking is tentatively associated with suicidal behavior. METHODS: Retrospective analysis of demographic and clinical factors among 352 longitudinally assessed DSM-IV types I and II BPD patients contrasted patients with versus without consumption of nicotine or caffeine, based on univariate comparisons and multiple regression modeling...

Caffeine is the most widely consumed psychoactive substance and is a legal stimulant that is readily available to children. Caffeine has occasionally been considered a drug of abuse and the potential for dependence on caffeine has been debated. Presently, due to a paucity of clinical evidence on caffeine dependence or abuse, no such diagnosis is included in the Diagnostic and Statistical Manual of Mental Disorder-fourth edition. The authors present two cases of abuse or dependence on the caffeine contained in 'eutrophic' (energy/nutritional) beverages or caffeine preparations, followed by a review of clinical studies demonstrating evidence that some people can manifest a clinical syndrome of caffeine dependence or abuse...

BACKGROUND: Notwithstanding the emerging literature on comorbidity between obsessive-compulsive disorder (OCD) and bipolar disorder, relatively few systematic data exist on the clinical characteristics of this interface and its treatment. The aim of the present study is to address this challenge as it appears in a setting of routine clinical practice. METHOD: The sample comprised 68 patients with comorbid DSM-IV diagnoses of OCD and major depressive episode admitted and treated at the day-hospital in the Department of Psychiatry at the University of Pisa (Pisa, Italy) during a 3-year period (January 1995-December 1998)...

OBJECTIVE: Overweight and obesity are common clinical problems encountered in the treatment of bipolar disorder. We therefore assessed the prevalence and clinical correlates of overweight, obesity, and extreme obesity in 644 bipolar patients. METHOD: 644 outpatients with DSM-IV bipolar disorder in the Stanley Foundation Bipolar Treatment Outcomes Network were evaluated with structured diagnostic interviews and clinician- and self-administered questionnaires to determine bipolar disorder diagnoses, demographic and historical illness characteristics, comorbid Axis I diagnoses, medical histories, health habits, and body mass indices (BMMs)...

The prevalence of smoking among psychiatric outpatients (N = 277) was significantly higher than among either local or national population-based samples (N = 1,440 and 17,000) (52% versus 30% and 33%). The higher prevalence was not associated with the age, sex, marital status, socioeconomic status, alcohol use, coffee use, or institutionalization of the psychiatric patients. Smoking was especially prevalent among patients with schizophrenia (88%) or mania (70%) and among the more severely ill patients. Hypotheses about why psychiatric patients are more likely to smoke and why they do not have a high rate of smoking-induced illnesses are presented...

Caffeine increases anxiety in people with anxiety disorders. To determine whether caffeine exerts a similar effect in depression, the authors compared retrospective reports of caffeine intake and symptoms produced by caffeine ingestion in patients with panic disorder, patients with major depression, and control subjects. Panic patients consumed less caffeine and reported more symptoms than depressed or control subjects. Although depressed patients did not differ from control subjects in caffeine intake or most symptoms, more depressed patients reported that caffeine induced anxiety...

Lithium tremor worsened in two patients when caffeine (coffee) was eliminated from their diets. An associated reduction in renal lithium clearance resulting in increased serum lithium level is thought to be the mechanism.
