The impact of prescribed psychotropics on youth

Shaheen E Lakhan and Gareth E Hagger-Johnson — 2007-10-20

Many psychotropics prescribed to children are unlicensed or off-label. This article uses the two most prescribed psychotropics (MPH and SSRIs) to illustrate various concerns about their impact on youth. Many mental illnesses begin in childhood or early adulthood, warranting a treatment of some kind. However, commentators have argued that prescribing is influenced by five myths: (1) children are little adults; (2) children have no reason to develop depression or anxiety; (3) psychiatric disorders are the same across adults and children; (3) children can be prescribed lower doses of the same drug; (5) drugs are preferable to alternative treatments and are more successful. Several lines of evidence suggest that these are incorrect assumptions. We update readers with recent research in relation to these myths, concluding that researchers should clarify child/adult differences for psychotropics, attend to the growth of "cosmetic" use of psychotropics in children and adolescents, and address concerns about the diagnostic validity of mental illness in the current DSM classification system.

Duloxetine and suicide attempts: a possible relation

Bilal A Salem and Elie G Karam — 2008-06-11

The possible increase of suicidal ideation with some antidepressants is still a matter of debate. We are reporting two cases of suicidal attempt that occurred concomitantly with the use of Duloxetine. To our knowledge there is no prior publication about a possible Duloxetine related increase in the risk of suicidality .

Knowledge about childhood autism among health workers (KCAHW) questionnaire: description, reliability and internal consistency

Muideen O Bakare, Peter O Ebigbo, Ahamefule O Agomoh and Nkem C Menkiti — 2008-06-06

Background: Knowledge and awareness about childhood autism is low among health workers and the general community in Nigeria and other Sub-Saharan African countries. Poor knowledge and awareness about childhood autism, especially among health workers can compromise early recognition and interventions which had been known to improve prognosis in children with autism. In formulating policy and designing interventions for these children, there is need to develop a reliable tool that can be used in assessing baseline knowledge about childhood autism among health workers and the impact that future continued education and awareness campaign may have on such baseline knowledge. Knowledge about childhood autism among health workers (KCAHW) questionnaire was designed for this purpose. Methods: The KCAHW questionnaire is a nineteen (19) item self-administered questionnaire that is divided into four domains. KCAHW questionnaires were distributed to fifty (50) psychiatric nurses involved in community mental health services in South-Eastern Nigeria to complete. After two weeks period, the KCAHW questionnaires were re-administered to the same fifty (50) psychiatric nurses to assess their knowledge about childhood autism and to assess the test-retest reliability and internal consistency of this questionnaire. Results: KCAHW questionnaire showed good test-retest reliability when the mean domain and total scores at first and second time administration were compared. The four mean domain scores and the mean total scores at first and second time administration were significantly correlated. The questionnaire also had a good overall internal consistency when the mean scores of the four domains were correlated with mean total scores (Cronbach's alpha = 0.97). Conclusion: The KCAHW questionnaire is a reliable tool for assessing knowledge of health workers about childhood autism. It would be a useful tool in improving early recognition of features of autism among affected children in Sub-Saharan African and other developing countries of the world where knowledge and awareness about childhood autism is low.

Affective psychosis, Hashimoto's thyroiditis, and brain perfusion abnormalities: case report

2007-12-20

Background: It has recently become evident that circulating thyroid antibodies are found in excess among patients suffering from mood disorders. Moreover, a manic episode associated with Hashimoto's thyroiditis has recently been reported as the first case of bipolar disorder due to Hashimoto's encephalopathy. We report a case in which Hashimoto's thyroiditis was suspected to be involved in the deteriorating course of mood disorder and discuss potential pathogenic mechanisms linking thyroid autoimmunity with psychopathology.Case presentationA 43-year-old woman, with a history of recurrent depression since the age of 31, developed manic, psychotic, and soft neurological symptoms across the last three years in concomitance with her first diagnosis of Hashimoto's thyroiditis. The patient underwent a thorough medical and neurological workup. Circulating thyroperoxidase antibodies were highly elevated but thyroid function was adequately maintained with L-thyroxine substitution. EEG was normal and no other signs of current CNS inflammation were evidenced. However, brain magnetic resonance imaging evidenced several non-active lesions in the white matter from both hemispheres, suggestive of a non-specific past vasculitis. Brain single-photon emission computed tomography showed cortical perfusion asymmetry particularly between frontal lobes. Conclusion: We hypothesize that abnormalities in cortical perfusion might represent a pathogenic link between thyroid autoimmunity and mood disorders, and that the rare cases of severe Hashimoto's encephalopathy presenting with mood disorder might be only the tip of an iceberg.

Animal-assisted therapy with farm animals for persons with psychiatric disorders: effects on self-efficacy, coping ability and quality of life, a randomized controlled trial

Bente Berget, Øivind Ekeberg and Bjarne O Braastad — 2008-04-11

Background: The benefits of Animal-Assisted Therapy (AAT) for humans with mental disorders have been well-documented using cats and dogs, but there is a complete lack of controlled studies using farm animals as therapeutic agents for psychiatric patients. The study was developed in the context of Green care, a concept that involves the use of farm animals, plants, gardens, or the landscape in recreational or work-related interventions for different target groups of clients in cooperation with health authorities. The present study aimed at examining effects of a 12-week intervention with farm animals on self-efficacy, coping ability and quality of life among adult psychiatric patients with a variety of psychiatric diagnoses. Methods: The study was a randomized controlled trial and follow-up. Ninety patients (59 women and 31 men) with schizophrenia, affective disorders, anxiety, and personality disorders completed questionnaires to assess self-efficacy (Generalized Self-Efficacy Scale; GSE), coping ability (Coping Strategies Scale), and quality of life (Quality of Life Scale; QOLS-N) before, at the end of intervention, and at six months follow-up. Two-thirds of the patients (N = 60) were given interventions; the remaining served as controls. Results: There was significant increase in self-efficacy in the treatment group but not in the control group from before intervention (SB) to six months follow-up (SSMA), (SSMA-SB; F1,55 = 4.20, p= 0.05) and from end of intervention (SA) to follow-up (SSMA-SA; F1,55 = 5.6, p= 0.02). There was significant increase in coping ability within the treatment group between before intervention and follow-up (SSMA-SB = 2.7, t = 2.31, p = 0.03), whereas no changes in quality of life was found. There were no significant changes in any of the variables during the intervention. Conclusion: AAT with farm animals may have positive influences on self-efficacy and coping ability among psychiatric patients with long lasting psychiatric symptoms.

What every psychiatrist should know about PANDAS: a review

2008-05-21

The term Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus infections (PANDAS) was coined by Swedo et al. in 1998 to describe a subset of childhood obsessive-compulsive disorders (OCD) and tic disorders triggered by group-A beta-hemolytic Streptococcus pyogenes infection. Like adult OCD, PANDAS is associated with basal ganglia dysfunction. Other putative pathogenetic mechanisms of PANDAS include molecular mimicry and autoimmune-mediated altered neuronal signaling, involving calcium-calmodulin dependent protein (CaM) kinase II activity. Nonetheless the contrasting results from numerous studies provide no consensus on whether PANDAS should be considered as a specific nosological entity or simply a useful research framework. Herein we discuss available data that could provide insight into pathophysiology of adult OCD, or might explain cases of treatment-resistance. We also review the latest research findings on diagnostic and treatment.

The relationship between anxiety, depression and illness perception in tberculosis patients in Pakistan

2008-02-26

ObjectiveAs the rates of TB world over have increased during the past 10 years, there has been a growing awareness of depression and its role in the outcome of chronic disorders. Though depression is common in patients with TB no study as yet has examined the prevalence of depression in this group in Pakistan. We aimed to determine the presence of depression, anxiety and illness perceptions in patients suffering from Tuberculosis (TB) in Pakistan. Methods: 108 consecutive outpatients with tuberculosis completed the Hospital Anxiety and Depression scale (HADS) and the Illness Perception Questionnaire (IPQ). Results: Out of 108 patients, 50 (46.3%) were depressed and 51 (47.2%) had anxiety. Raised depression and anxiety scores were associated with an increase in the number of symptoms reported (HADS Depression: r = 0.346, p = < 0.001), more serious perceived consequences (HADS Depression: r = 0.279, p = 0.004, HADS Anxiety: r = 0.234, p = 0.017) and less control over their illness (HADS Depression: r = 0.239, p = 0.014, HADS Anxiety: r = 0.271, p = 0.005). Conclusion: We found that about a half of patients in our sample met the criteria for probable depression and anxiety based on HADS score. Negative illness perceptions were clearly related to reports of mood symptoms. As depression and lack of perceived control over illness in those suffering from tuberculosis are reported to be independent predictors of poor adherence further studies to investigate their relationship with medication adherence are required.

Immigration, social integration and mental health in Norway, with focus on gender differences

Odd Steffen Dalgard and Suraj Bahadur Thapa — 2007-10-30

Background: Studies have shown that social integration may have a positive as well as a negative effect on the mental health of immigrants, depending on the social circumstances.Aims of the studyTo investigate the relationship between social integration and psychological distress in immigrants in Oslo, Norway, with focus on gender differences. Methods: The study was based on data from a community survey in Oslo (N = 15899), and included 1448 immigrants from non-Western and 1059 immigrants from Western countries. Psychological distress was measured by a 10 items version of Hopkins Symptom Check List (HSCL-10), and social integration was measured by an index based on four items: Knowledge of the Norwegian language, reading Norwegian newspapers, visits by Norwegians and receiving help from Norwegians. Information on paid employment, household income, marital status, social support and conflicts in intimate relationships was also included in the study. Results: The non-western immigrants showed a higher level of psychological distress than the immigrants from western countries. In men this could be explained by the combination of less social integration, less employment, lower income, less social support and more conflicts in intimate relationships among non-western compared to western immigrants. In women the difference in level of psychological stress could not be explained by these variables, even if it was reduced. A reason for this seemed to be that social integration in non-western immigrants had a different effect on mental health in men and women. In men, social integration showed a positive effect through employment and income, as well as a positive effect in other areas. Also in non-western women social integration showed a positive effect through greater access to employment and income, but this effect was levelled out by integration causing problems in other areas. Conclusion: Unexpectedly, social integration in non-western immigrants was associated with good mental health in men, but not in women. A possible explanation for this might be that the traditional female role in these countries is more challenged by social integration into a Western country than the male role, resulting in conflicting norms, threat to the self and/or loss of identity.

Quetiapine as add-on treatment for bipolar I disorder: efficacy in preventing relapse of depressive episodes

2007-09-24

ObjectiveTo assess the long-term response to add-on quetiapine therapy in patients with bipolar I disorder who were not adequately responding to standard medications. Methods: Outpatients with bipolar I disorder (DSM-IV-TR) responding inadequately to standard treatment were observed before and after the addition of quetiapine. Symptom severity was evaluated using the Clinical Global Impressions scale for Bipolar Disorder (CGI-BP) each month. Relapses included hospitalization, treatment in a day hospital or clinic, scores ≥ 1 point higher than previous CGI-BP scores and/or upward titration of quetiapine or other medications. Results: Sixty-one patients (age range of 18–68 years) were observed prospectively for an average of 7.5 months (range 3–18 months) prior to addition of quetiapine and subsequently followed for an average of 15.7 months (range 6–42 months). The final mean quetiapine dose was 537.1 ± 91.7 mg/d. Prior to quetiapine addition, an annual relapse rate of 2.09 episodes was recorded, relating to 0.94 depressive and 1.15 manic or mixed episodes. Following quetiapine addition, annual relapse rates were reduced to 0.61 episodes, representing 0.14 depressive and 0.46 manic or mixed episodes. Compared with the period of add-on quetiapine treatment, the relative risk of relapse prior to quetiapine therapy was 3.4 for all episodes (χ2 = 24.8, P < 0.001), 6.7 for depressive episodes (χ2 = 24.7, P < 0.001), and 2.5 for manic or mixed episodes (χ2 = 9.0, P < 0.05). Conclusion: This naturalistic follow-up study provides preliminary evidence for the efficacy of long-term add-on quetiapine treatment in the prevention of relapses of manic or mixed and depressive episodes of bipolar I disorder, and particularly in the prevention of depressive episodes.

Executive function abnormalities in pathological gamblers

2008-03-27

Background: Pathological gambling (PG) is an impulse control disorder characterized by persistent and maladaptive gambling behaviors with disruptive consequences for familial, occupational and social functions. The pathophysiology of PG is still unclear, but it is hypothesized that it might include environmental factors coupled with a genetic vulnerability and dysfunctions of different neurotransmitters and selected brain areas. Our study aimed to evaluate a group of patients suffering from PG by means of some neuropsychological tests in order to explore the brain areas related to the disorder. Methods: Twenty outpatients (15 men, 5 women), with a diagnosis of PG according to DSM-IV criteria, were included in the study and evaluated with a battery of neuropsychological tests: the Wisconsin Card Sorting Test (WCST), the Wechsler Memory Scale revised (WMS-R) and the Verbal Associative Fluency Test (FAS). The results obtained in the patients were compared with normative values of matched healthy control subjects. Results: The PG patients showed alterations at the WCST only, in particular they had a great difficulty in finding alternative methods of problem-solving and showed a decrease, rather than an increase, in efficiency, as they progressed through the consecutive phases of the test. The mean scores of the other tests were within the normal range. Conclusion: Our findings showed that patients affected by PG, in spite of normal intellectual, linguistic and visual-spatial abilities, had abnormalities emerging from the WCST, in particular they could not learn from their mistakes and look for alternative solutions. Our results would seem to confirm an altered functioning of the prefrontal areas which might provoke a sort of cognitive "rigidity" that might predispose to the development of impulsive and/or compulsive behaviors, such as those typical of PG.
