  • Subjective Memory Immediately Following Electroconvulsive Therapy
  • 2017
  • Ingår i: Journal of ECT. - Philadelphia, USA : Lippincott Williams & Wilkins. - 1095-0680. ; 33:2, s. 96-103
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: The aims of the present study were to describe the short-term rate of subjective memory worsening (SMW) and identify factors of importance for SMW in a large clinical sample treated for depression with electroconvulsive therapy (ECT).Methods: This register-based study included 1212 patients from the Swedish National Quality Register for ECT. Subjective memory worsening was defined as a 2-point worsening on the memory item of the Comprehensive Psychopathological Rating Scale from before to within 1 week after treatment. Associations between patient characteristics and treatment factors were examined using logistic regression.Results: Subjective memory worsening was experienced in 26%. It was more common in women than in men (31% vs 18%; P < 0.001) and more common in patients aged 18 to 39 years than in patients 65 years or older (32% vs 22%; P = 0.008). Patients with less subjective memory disturbances before ECT had a greater risk of SMW. Patients in remission after ECT had a lower risk of SMW. A brief pulse width stimulus gave higher risk of SMW compared with ultrabrief pulse (odds ratio, 1.61; 95% confidence interval, 1.05-2.47).Conclusions: Subjective memory worsening is reported by a minority of patients. However, young women are at risk of experiencing SMW. Ultrabrief pulse width stimulus could be considered for patients treated with unilateral electrode placement who experience SMW. Each patient should be monitored with regard to symptoms and adverse effects, and treatment should be adjusted on an individual basis to maximize the clinical effect and with efforts to minimize the cognitive adverse effects.

  • Acute intermittent porphyria : comorbidity and shared familial risks with schizophrenia and bipolar disorder in Sweden
  • 2015
  • Ingår i: British Journal of Psychiatry. - London, United Kingdom : Royal College of Psychiatrists. - 0007-1250. ; 207:6, s. 556-557
  • Tidskriftsartikel (refereegranskat)abstract
    • Acute intermittent porphyria (AIP) has been associated with schizophrenia in some studies, but prior research is limited by the absence of comparison populations. Here, we linked Swedish registers to examine the risk of schizophrenia and bipolar disorder in 717 individuals diagnosed with AIP and their first-degree relatives, compared with matched individuals without AIP and their first-degree relatives. Individuals with AIP had a fourfold increased risk of schizophrenia or bipolar disorder. Similarly, relatives of individuals with AIP had double the risk of schizophrenia or bipolar disorder, suggesting that these associations may be as a result of common genetic influences.

  • Klinefelter syndrome and risk of psychosis, autism and ADHD
  • 2014
  • Ingår i: Journal of Psychiatric Research. - Oxford, USA : Elsevier. - 0022-3956. ; 48:1, s. 128-130
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Schizophrenia, bipolar disorder, autism spectrum disorders and ADHD might be overrepresented in Klinefelter syndrome, but previous investigations have yielded inconclusive results.Methods: We compared a national sample of 860 Klinefelter patients in Sweden with 86 000 matched population controls. To assess the risks of schizophrenia, bipolar disorder, autism spectrum disorder and ADHD in Klinefelter patients, we estimated odds ratios and 95% confidence intervals using conditional logistic regressions.Results: Klinefelter patients had almost four times higher risks of schizophrenia, odds ratio (OR) = 3.6, 95% confidence interval (CI) 2.0-6.7 and bipolar disorder (OR = 3.8, CI 1.8-7.6) and about six times higher risk of autism spectrum disorder (OR = 6.2, CI 4.0-9.4) and ADHD (OR = 5.6, CI 4.0-7.8).Conclusions: The risk of psychosis, autism and ADHD is increased in Klinefelter patients. These findings indicate an X chromosome-related factor in the etiology of the studied psychiatric disorders, and may also have implications for treatment of patients with Klinefelter syndrome.

  • Obsessive-Compulsive Disorder, Psychosis, and Bipolarity A Longitudinal Cohort and Multigenerational Family Study
  • 2015
  • Ingår i: Schizophrenia Bulletin. - Oxford, United Kingdom : Oxford University Press. - 0586-7614. ; 41:5, s. 1076-1083
  • Tidskriftsartikel (refereegranskat)abstract
    • Obsessive-compulsive disorder (OCD) often co-occurs with psychotic and bipolar disorders; this comorbidity complicates the clinical management of these conditions. In this population-based longitudinal and multigenerational family study, we examined the patterns of comorbidity, longitudinal risks, and shared familial risks between these disorders. Participants were individuals with a diagnosis of OCD (n = 19,814), schizophrenia (n = 58,336), bipolar disorder (n = 48,180), and schizoaffective disorder (n = 14,904) included in the Swedish Patient Register between January 1969 and December 2009; their first-, second-, and third-degree relatives; and population-matched (1:10 ratio) unaffected comparison individuals and their relatives. The Swedish Prescribed Drug Register was used to control for the potential effect of medication in the longitudinal analyses. Individuals with OCD had a 12-fold increased risk of having a comorbid diagnosis of schizophrenia and a 13-fold increased risk of bipolar disorder and schizoaffective disorder. Longitudinal analyses showed that individuals first diagnosed with OCD had an increased risk for later diagnosis of all other disorders, and vice versa. The risk of bipolar disorder was reduced, but not eliminated, when the use of selective serotonin reuptake inhibitors was adjusted for. OCD-unaffected first-, second-, and third-degree relatives of probands with OCD had a significantly increased risk for all 3 disorders; the magnitude of this risk decreased as the genetic distance increased. We conclude that OCD is etiologically related to both schizophrenia spectrum and bipolar disorders. The results have implications for current gene-searching efforts and for clinical practice.

  • The association between Darier disease, bipolar disorder, and schizophrenia revisited: a population-based family study.
  • 2015
  • Ingår i: Bipolar disorders. - 1399-5618. ; 17:3, s. 340-4
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: Darier disease is an autosomal dominant skin disorder caused by mutations in the ATPase, Ca++ transporting, cardiac muscle, slow twitch 2 (ATP2A2) gene and previously reported to cosegregate with bipolar disorder and schizophrenia in occasional pedigrees. It is, however, unknown whether these associations exist also in the general population, and the objective of this study was to examine this question.Methods: We compared a national sample of individuals with Darier disease and their first-degree relatives with matched unexposed individuals from the general population and their first-degree relatives, respectively. To examine risks for bipolar disorder and schizophrenia, risk ratios and 95% confidence intervals (CIs) were estimated using conditional logistic regressions.Results: Individuals with Darier disease had a 4.3 times higher risk of being diagnosed with bipolar disorder (95% CI: 2.6-7.3) and a 2.3 times higher risk of being diagnosed with schizophrenia (95% CI: 1.1-5.2) than matched individuals from the general population. Relatives of individuals with Darier disease had a 1.6 times higher risk of having bipolar disorder (95% CI: 1.1-2.5) than relatives of matched individuals from the general population, but no increased risk of schizophrenia (risk ratio = 0.8, 95% CI: 0.4-1.8).Conclusions: The association between Darier disease and bipolar disorder is manifest also in the population, and our data suggest that genetic variability within the ATP2A2 gene that causes Darier disease also confers susceptibility for bipolar disorder. The Darier-causing mutations merit additional attention in molecular genetic research on bipolar disorder.

  • Polycystic ovary syndrome and psychiatric disorders: Co-morbidity and heritability in a nationwide Swedish cohort.
  • 2016
  • Ingår i: Psychoneuroendocrinology. - 1873-3360. ; 73, s. 196-203
  • Tidskriftsartikel (refereegranskat)abstract
    • Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting 5-15% of reproductive-aged women and characterized by high levels of circulating androgens. Given that androgens have been implicated in the aetiology of several psychiatric disorders, it was hypothesized that women with PCOS have high risk for psychiatric comorbidity. We aimed to investigate this risk amongst women with PCOS, as well as in their siblings, to elucidate if familial factors underlie any potential associations. Using the Swedish national registers, we identified all women diagnosed with PCOS between 1990 and 2013 (n=24,385), their full-siblings (n=25,921), plus matched individuals (1:10/100) from the general population and their full-siblings. Psychiatric disorder diagnoses were identified including schizophrenia, bipolar disorder, depressive and anxiety disorders, eating disorders, personality and gender identity disorder, autism spectrum disorder (ASD), attention-deficit hyperactivity disorder (ADHD), tics, attempted and completed suicide. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using conditional logistic regression and adjusted ORs (AOR) were determined by adjustment for comorbid psychiatric disorders. Overall, women with PCOS had an increased odds of having at least one psychiatric disorder (OR=1.56 [95CI%, 1.51-1.61]). Crude ORs showed associations with nearly all psychiatric disorders included in this study. Following adjustment for comorbid psychiatric disorders, women with PCOS were still at a significantly increased risk for bulimia, schizophrenia, bipolar disorder, depressive and anxiety disorders, personality disorders, with the highest AORs for ASD (AOR=1.55 [95%CI, 1.32-1.81]) and tics (AOR=1.65 [95%CI, 1.10-2.47]). Significantly higher AORs were found for ASD in both brothers and sisters of women with PCOS, and for depressive, anxiety, and schizophrenia spectrum disorders in the sisters only. Notably, the crude ORs for attempted suicide were 40% higher in women with PCOS and 16% higher in their unaffected sisters. However, the AORs were greatly attenuated indicating that underlying psychiatric comorbidity is important for this association. Women with PCOS had higher risks for a range of psychiatric disorders not shown before. Elevated risk in their siblings suggests shared familial factors between PCOS and psychiatric disorders. This study is an important first step towards identifying the underlying mechanisms for risk of psychiatric disorders in women with PCOS. Health professionals treating women with PCOS should be aware that these patients - as well as their family members - are important targets for mental health care.

  • A History of Psychosis in Bipolar Disorder is Associated With Gray Matter Volume Reduction.
  • 2017
  • Ingår i: Schizophrenia bulletin. - 1745-1701. ; 43:1, s. 99-107
  • Tidskriftsartikel (refereegranskat)abstract
    • Psychotic symptoms are prevalent in schizophrenia, bipolar disorder, and other psychiatric and neurological disorders, yet the neurobiological underpinnings of psychosis remain obscure. In the last decade, a large number of magnetic resonance imaging studies have shown differences in local gray matter volume between patients with different psychiatric syndromes and healthy controls. Few studies have focused on the symptoms, which these syndromes are constituted of. Here, we test the association between psychosis and gray matter volume by using a sample of 167 subjects with bipolar disorder, with and without a history of psychosis, and 102 healthy controls. Magnetic resonance images were analyzed on group level using a voxel-wise mass univariate analysis (Voxel-Based Morphometry). We found that patients with a history of psychosis had smaller gray matter volume in left fusiform gyrus, the right rostral dorsolateral prefrontal cortex, and the left inferior frontal gyrus compared with patients without psychosis and with healthy controls. There was no volume difference in these areas between the no-psychosis group and healthy controls. These areas have previously been structurally and functionally coupled to delusions and hallucinations. Our finding adds further evidence to the probability of these regions as key areas in the development of psychotic symptoms.

  • The Societal Cost of Schizophrenia in Sweden
  • 2013
  • Ingår i: Journal of Mental Health Policy and Economics. - 1091-4358. ; 16:1, s. 13-25
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Schizophrenia is a disabling psychiatric disorder that has severe consequences for patients and their families. Moreover, the expensive treatment of schizophrenia imposes a burden on health care providers and the wider society. Existing cost estimates for Sweden, however, are based on relatively small patient populations and need to be confirmed in a large register-based study. Aims of the Study: To investigate the health care resource utilization and cost-of-illness in patients with schizophrenia in Sweden and to relate the costs to hospitalizations and global assessment of functioning (GAF). Methods: Hospital-based registry data were combined with national registry data from a large patient population to get reliable estimates of the costs of schizophrenia in Sweden. Schizophrenia was defined by ICD-10 codes F20; F21; F23.1,2,8,9; F25.1,8,9. Registry data on socio-demographics and disease-related healthcare resource use in outpatient and inpatient care were obtained from Northern Stockholm Psychiatry. Data on pharmaceuticals were obtained from the National Board of Health and Welfare, and data on sick leave and early retirement were obtained from the Swedish Social Insurance Agency. Costs for community mental health care were not available at the individual level, but were estimated based on previous studies and aggregate cost data from Stockholm. Resource use data from the registries were combined with unit costs from publicly available sources. The study was conducted from a societal perspective, with indirect costs valued according to the human capital method. Results: The average annual psychiatric cost per patient with schizophrenia in 2008 was 42 700 (95% CI: 41 500 44 000), based on a sample of 2 161 patients. To this should be added costs for community mental health care of 12 400 per patient, giving a total cost of 55 100 per patient. The two largest cost items in the total costs were indirect costs due to lost productivity (60%) and community mental health care (22% of the total cost). Patients who were hospitalized in 2008 had greater psychiatric costs than those who were not, (sic)71 700 vs. (sic)37 700 (p<0.0001). Psychiatric costs were significantly and negatively correlated with GAF (p<0.001). Discussion: The major strengths of the study are the relatively large sample, and the linkage of patient-level clinical data on inpatient and outpatient care with national registry data on prescription pharmaceuticals, and days on social insurance. A limitation was that costs for informal care and primary care were not included in the data, but previous studies suggest that these costs items are small compared to other costs for schizophrenia. Implications for Health Policies and Future Research: Costs were strongly related to hospitalization and GAF, suggesting that attempts to improve global functioning and avoid hospitalizations by means of effective treatment and rehabilitation might not only decrease suffering for patients and relatives, but also reduce the societal cost of schizophrenia. A detailed knowledge of the societal costs can also be helpful in evaluating the cost-effectiveness of new treatment strategies to improve the care for patients with schizophrenia.
