Correlates of Incident Cognitive Impairment in the REasons for Geographic and Racial Differences in Stroke (REGARDS) Study

Objective: To identify approximately 500 cases of incident cognitive impairment (ICI) in a large, national sample adapting an existing cognitive test-based case definition and to examine relationships of vascular risk factors with ICI. Method: Participants were from the REGARDS study, a national sample of 30,239 African-American and White Americans. Participants included in this analysis had normal cognitive screening and no history of stroke at baseline, and at least one follow-up cognitive assessment with a three-test battery (TTB). Regression-based norms were applied to TTB scores to identify cases of ICI. Logistic regression was used to model associations with baseline vascular risk factors. Results: We identified 495 participants with ICI of 17,630 eligible participants. In multivariable modeling, income (OR 1.83 CI 1.27,2.62), stroke belt residence (OR 1.45 CI 1.18,1.78), history of transient ischemic attack (OR 1.90 CI 1.29,2.81), coronary artery disease(OR 1.32 CI 1.02,1.70), diabetes (OR 1.48 CI 1.17,1.87), obesity (OR 1.40 CI 1.05,1.86), and incident stroke (OR 2.73 CI 1.52,4.90) were associated with ICI. Conclusions: We adapted a previously validated cognitive test-based case definition to identify cases of ICI. Many previously identified risk factors were associated with ICI, supporting the criterion-related validity of our definition.     

The impact of child sexual abuse on the course of bipolar disorder: a systematic review

Maniglio R. The impact of child sexual abuse on the course of bipolar disorder: a systematic review.
Bipolar Disord 2013: 15: 341–358. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd. Objectives: The aim of this review was to elucidate the impact of child sexual abuse on all clinical phenomena that occur after the onset of bipolar disorder, including associated clinical features that are not part of the diagnostic criteria for the disorder. Methods: Five databases were searched and supplemented with a hand search of reference lists from retrieved papers. Study quality was assessed using a validated quality assessment tool. Blind assessments of study eligibility and quality were conducted by two independent researchers to reduce bias, minimize errors, and enhance the reliability of findings. Disagreements were resolved by consensus. Results: Eighteen studies that included a total of 2996 adults and youths with bipolar disorder and met the minimum quality criteria necessary to ensure objectivity and not invalidate results were analyzed. Across studies, child sexual abuse was strongly (and perhaps directly) associated with posttraumatic stress disorder; whereas it was less strongly (and perhaps indirectly) related to suicide attempts, alcohol and/or drug abuse or dependence, psychotic symptoms, and an early age of illness onset. In regard to the association between child sexual abuse and other clinical variables concerning the course of bipolar disorder, evidence was scant or conflicting. Conclusions: Child sexual abuse is associated (either directly or indirectly) with some clinical phenomena that represent a more severe form of bipolar disorder. Although such a traumatic experience may directly affect the development of posttraumatic stress disorder, the effects of early sexual abuse on later suicidal behavior, substance abuse, and psychotic symptoms may operate through the mediating influences of certain psychopathological or neurobiological variables.     

Behavioral parent training to address sleep disturbances in young children with autism spectrum disorder: a pilot trial

Objectives

A large percentage of children with autism spectrum disorders (ASD) have bedtime and sleep disturbances. However, the treatment of these disturbances has been understudied. The purpose of our study was to develop a manualized behavioral parent training (BPT) program for parents of young children with ASD and sleep disturbances and to test the feasibility, fidelity, and initial efficacy of the treatment in a small randomized controlled trial (RCT).

Participants and methods

Parents of a sample of 40 young children diagnosed with ASD with an average age of 3.5 years were enrolled in our study. Participants were randomized to either the BPT program group or a comparison group who were given nonsleep-related parent education. Each participant was individually administered a 5-session program delivered over the 8-week study. Outcome measures of feasibility, fidelity, and efficacy were collected at weeks 4 and 8 after the baseline time point. Children’s sleep was assessed by parent report and objectively by actigraphy.

Results

Of the 20 participants in each group, data were available for 15 participants randomized to BPT and 18 participants randomized to the comparison condition. Results supported the feasibility of the manualized parent training program and the comparison program. Treatment fidelity was high for both groups. The BPT program group significantly improved more than the comparison group based on the primary sleep outcome of parent report. There were no objective changes in sleep detected by actigraphy.

Conclusions

Our study is one of few RCTs of a BPT program to specifically target sleep disturbances in a well-characterized sample of young children with ASD and to demonstrate the feasibility of the approach. Initial efficacy favored the BPT program over the comparison group and suggested that this manualized parent training approach is worthy of further examination of the efficacy within a larger RCT.     

Screening for sleep dysfunction after traumatic brain injury

Numerous studies on the high prevalence of sleep disorders in individuals with traumatic brain injury (TBI) have been conducted in the past few decades. These disorders can accentuate other consequences of TBI, negatively impacting mood, exacerbating pain, heightening irritability, and diminishing cognitive abilities and the potential for recovery. Nevertheless, sleep is not routinely assessed in this population. In our review, we examined the selective screening criteria and the scientific evidence regarding screening for post-TBI sleep disorders to identify gaps in our knowledge that are in need of resolution. We retrieved papers written in the English-language literature before June 2012 pertinent to the discussion on sleep after TBI found through a PubMed search. Within our research, we found that sleep dysfunction is highly burdensome after TBI, treatment interventions for some sleep disorders result in favorable outcomes, sensitive and specific tests to detect sleep disorders are available, and the cost-effectiveness and sustainability of screening have been determined from other populations. The evidence we reviewed supports screening for post-TBI sleep dysfunction. This approach could improve the outcomes and reduce the risks for post-TBI adverse health and nonhealth effects (e.g., secondary injuries). A joint sleep and brain injury collaboration focusing on outcomes is needed to improve our knowledge.     

Prevalence and risk factors of hyperprolactinemia among patients with various psychiatric diagnoses and medications

Abstract

Objectives: Hyperprolactinemia is a common adverse event associated with psychotropic medications (mainly antipsychotics) used in the management of schizophrenia and bipolar disorders. The aim of this study was to estimate the prevalence of hyperprolactinemia in psychiatric patients and to evaluate its association with various psychiatric diagnoses and the use of various psychotropic medications.

Methods: A cross-sectional observational study was conducted between July 2012 and June 2014. Patients were recruited from a number of hospitals located in the five regions of Saudi Arabia. Hyperprolactinemia was defined as blood prolactin levels >25?ng/mL in females and >20?ng/mL in males, regardless of the presence of symptoms.

Results: A total of 997 patients (553 males and 444 females) were included in the current analysis. The average blood prolactin level was 32.6?±?44.1?ng/mL, with higher levels among females than males (42.9?±?61.3 versus 24.4?±?18.6, p?<?.001). The prevalence of hyperprolactinemia was 44.3%, with no significant gender difference (41.9% in females versus 46.3% in males, p?=?.164) but with huge variability according to individual antipsychotic and other psychotropic medications. In the multivariate analysis adjusted for demographic and clinical characteristics, hyperprolactinemia was independently and positively associated with using antipsychotic medications (OR?=?2.08, 1.26–3.42, p?=?.004). Additionally, previous hospitalisation, diabetes and hypothyroidism were positively associated, whereas having primary depressive disorders was negatively associated.

Conclusions: We report a high prevalence of hyperprolactinemia among a large sample of psychiatric patients in Saudi Arabia, which was linked to the use of antipsychotic medications. Routine measurement of blood prolactin levels for all patients maintained on antipsychotic agents is recommended, regardless of symptoms.     

Prevalence of insomnia symptoms: results from an urban district in Ankara,Turkey

Objective. Characteristics of insomnia symptoms in Turkey are not well established. The goal of this study was to determine the prevalence of insomnia and related symptoms in an urban district of Turkey. Method. The study was carried out in Ankara, in an urban district with a population of 2665. Out of the 1332 people in the sample, 1034 in the 15–65 age range were included in the study. Interviews were conducted according to the “Sleep Disorders Assessment Questionnaire” developed by the researchers. The Insomnia Severity Index (ISI) was also given to the subjects with a sleep problem to measure the subjective quality and quantity of insomnia symptoms. Results and conclusion. A total of 29.4% of all participants reported a sleep problem, out of which 23.7% defined one or more of the insomnia symptoms which included difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), early morning awakening (EMA), non-restorative sleep (NRS) and sleep deprivation (SD). Insomnia risk was found to be significantly increased with age, female sex, smoking and chronic medical illness. A total of 75.9% of participants who reported insomnia symptoms did not seek medical help for their complaint. According to the ISI, among the subjects with insomnia symptoms, 79 (32.2%) had subthreshold insomnia, 43 (17.6%) had clinical insomnia, 12 (4.9%) had severe clinical insomnia, while 88 (35.9%) did not score in the range indicating insomnia. The findings are discussed in the light of previous research and in relation to sociocultural factors emphasizing the need for public education on sleep disorders as medical conditions.     

Psychiatric disorders and left-handedness in children living in an urban environment

The objective of this study was to conduct an analysis of left-handed children treated in an urban mental health clinic to investigate the frequency and severity of psychiatric disorders compared to right-handed peers. Data on handedness, diagnoses, hospitalizations and severity of mental disorders were collected on 692 consecutive children, 4–18 years old (M = 10.1, SD = 3.2), referred for psychiatric evaluation. Left-handed children were 18.2% of patients in the study, a rate significantly higher than left-hand dominance in the USA (p < .05). Compared to children with right-handedness, logistic regression analysis yielded 31% [odds ratio (OR) = 1.31, 95% confidence interval (CI): 1.15–1.50] higher odds of having more psychiatric diagnosis, 70% (OR = 1.70, 95% CI: 1.10–2.62) increased odds of anxiety, 53% (OR = 1.53, 95% CI: 1.03–2.27) increased odds of depression and 78% (OR = 1.78, 95% CI: 1.21–2.62) increased odds of oppositional defiant disorder for children who were left-handed. Left-handed children had increased odds of being prescribed antipsychotic and anxiolytic medication uses, 53% and 86% increased odds, respectively, and 66% (OR = 1.66, 95% CI: 1.08–2.55) increased odds of psychiatric hospitalizations. Left-handedness was a phenotypic risk factor for psychiatric disorders and increased severity of psychiatric disorders.     

Suicidal and violent behaviour in mood disorders: A major public health problem. A review for the clinician

Abstract

Suicide attempt, and particularly completed suicide are relatively rare events in the community, but they are very common among psychiatric patients. Since over 90% of suicide victims suffer from (mostly untreated) current major mental disorders (particularly from major depressive episode), psychiatric risk factors are the clinically most useful predictors, especially if psychosocial and demographic risk factors are also pesent. Violent behaviours associated with mood disorders constitute a related yet independently also important aspect of this illness, and assessment and management of violence is a key component of everyday psychiatric practice. While most people with current mental disorder are not violent, violence is more common among seriously mentally ill individuals than in healthy persons. This is particularly true for untreated schizophrenics and untreated patients with major mood disorders, first of all in the cases of comorbid substance use disorders, mainly among those with current mania or postpartum depression. Although specific clinical studies are lacking, it is very lilely that successful acute and long-tem treatment of mood disorders can reduce the risk of violent behaviour in this patient population.     

Motives for Suicide Attempts--the Views of the Patients

This study was designed to investigate the motives patients give for attempting suicide and the associations between these motives and diagnosis, various psychiatric features, suicidal intent and socio-demographic characteristics. The Motives for Parasuicide Questionnaire (MPQ), comprising 14 suggested motives, was presented to 53 patients at a psychiatric ward that specialized in suicide attempters. Escape motives were very common, whereas interpersonal motives were rare. Patients with substance abuse, anxiety, or personality disorders more often chose communicating motives and mentioned higher numbers of motives than those with mood or adjustment disorders. Hopelessness was positively associated with a stated wish to die and with escape motives, and negatively correlated to communicating/unclear motives. Suicidal intent was related to some motives. The psychiatric disorder or mental state seems to be more important than socio-demographic characteristics for the choice of motives. Further studies are required to investigate the associations between psychiatric features and motives, as well as the clinical usefulness of such assessments.     

Prognosis of postpartum psychiatric disorders in a Turkish sample

Objective

The postpartum period represents a time of increased risk for psychiatric disorders. Postpartum depression is especially very common. Many aetiological risk factors have been reported for postpartum psychiatric disorders. The purpose of this study was to evaluate the postpartum psychiatric disorders in a Turkish sample and discuss their course.

Methods

The files of 6000 inpatients who were admitted to Gazi University School of Medicine Psychiatry Department were evaluated retrospectively, and 67 patients were chosen whose psychiatric illness had began puerperally. These patients were grouped according to age of onset of the illness, number of episodes and the type of these episodes, their postpartum psychiatric diagnoses and illness prognosis.

Results

Of 6000 patients, 67 (1.11%) were diagnosed as having a postpartum psychiatric disorder: 56.7% (n=38) were diagnosed as having a postpartum psychotic disorder, while 35.8% (n=24) as having an affective disorder. Forty-seven patients (70.1%) received a diagnosis of major psychiatric disorder during their follow-up.

Conclusion

These results show that postpartum diagnoses may show a chronic course and cause a life-time psychiatric illness and therefore patients should be monitored carefully for psychotic symptoms even after the acute period is over.
