The prevalence and clinical features of the night eating syndrome in psychiatric out-patient population.

OBJECTIVE: In this study we aimed to investigate the prevalance and clinical correlations of night eating syndrome (NES) in a sample of psychiatric outpatients. METHOD: Four hundred thirthy three consecutive psychiatric out-patients older than 18years were evaluated in the outpatient clinics using clinical interview according to the DSM-IV with regard to psychiatric diagnosis. Participants were also screened for presence of NES utilizing both clinical interview and self report based on Night Eating Questionnaire (NEQ) instruments. Sociodemographic and clinical features such as age, gender, education level, socioeconomic level and body mass index (BMI) were also recorded. The Body Shape Questionnaire (BSQ) and the Symptom Checklist-90 Revised (SCL-90R) were administered. RESULTS: Based on the proposed diagnostic criteria of the NES via utilizing clinical interview method, 97 (32 male, 65 female) of the sample met diagnostic criteria for NES. The point prevalence of NES was 22.4%. No statistically significant differences were found between the two groups in terms of age, gender, marital status, education and BMI. The patients with NES had higher NEQ, BSQ and SCL-90R subscale scores than patients without NES. Prevalance of depressive disorder, impulse control disorder, and nicotine dependency was higher among patients with NES. No differences were found with regard to the medication (antipsychotics, antidepressants and mood stabilizers). CONCLUSION: Night eating syndrome is prevalent among psychiatric outpatients and associated with depression, impulse control disorder, and nicotine dependency. Body dissatisfaction and higher symptom severity are also other risk factors for the development of NES.

Relationship of Internet addiction with cognitive style, personality, and depression in university students.

BACKGROUND: The aim of the study was to investigate the relationship of dysfunctional attitudes, self-esteem, personality, and depression with Internet addiction in university students. METHODS: A total of 720 university students participated in the study in Bülent Ecevit University English Preparatory School which offers intensive English courses. Students were evaluated with a sociodemographic data form, Beck Depression Inventory (BDI), Dysfunctional Attitudes Scale form A (DAS-A), Internet Addiction Scale (IAS), Rosenberg Self-Esteem Scale (RSES), and Eysenck Personality Questionnaire Revised/Abbreviated Form (EPQR-A). RESULTS: The results indicated that 52 (7.2%) of the students had Internet addiction. There were 37 (71.2%) men, 15 (28.8%) women in the addicted group. While the addicted groups' BDI, DAS-A perfectionistic attitude, need for approval, RSES, EPQR-A neuroticism, and psychoticism scores were significantly higher, EPQR-A lie scores were significantly lower than those of the non addicted group. According to the multiple binary logistic regression analysis, being male, duration of Internet usage, depression, and perfectionistic attitude have been found as predictors for Internet addiction. It has been found that perfectionistic attitude is a predictor for Internet addiction even when depression, sex, duration of Internet were controlled. CONCLUSIONS: To the knowledge of the researchers, this study is the first study to show the dysfunctional attitudes in Internet addiction. It can be important to evaluate dysfunctional attitudes, personality, self-esteem and depression in people with Internet addiction. These variables should be targeted for effective treatment of people with Internet addiction in cognitive behavioral therapy.

The mediator role of ruminative thinking style in the relationship between dysfunctional attitudes and depression.

BACKGROUND: The main aim of the present study was to examine whether ruminative thinking styles (brooding and reflection) mediate the effects of dysfunctional attitudes on depressive symptoms. METHODS: 120 psychotropic drug-naive first episode depression patients recruited from Bulent Ecevit University School of Medicine psychiatry department and Zonguldak State Hospital psychiatry department outpatient clinics were involved in the study. Participants completed the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Beck Depression Inventory (BDI), Dysfunctional Attitude Scale (DAS) and Ruminative Responses Scale (RRS-short version). Regression analyses together with the Sobel tests were performed for testing the mediator hypothesis. RESULTS: According to the path model, the level of brooding fully mediated the relationship between dysfunctional attitudes and depressive symptomatology but reflection did not play a mediator role in the relationship between dysfunctional attitudes and depressive symptoms. CONCLUSIONS: Assessment of brooding with both mental status examination and specific measurements and focusing on brooding as an intervention strategy would be beneficial components for an effective treatment of depression.

The comorbidity of adult attention-deficit/hyperactivity disorder in bipolar disorder patients.

OBJECTIVE: High comorbidity ratio of bipolar mood disorder (BMD) with Axis I and Axis II diagnoses is reported in the literature. The possible relationship between BMD and attention-deficit/hyperactivity disorder (ADHD) in all age groups has been attracting more attention of researchers due to highly overlapping symptoms such as excessive talking, attention deficit, and increased motor activity. In this study, we aimed to investigate the prevalence of ADHD comorbidity in BMD patients and the clinical features of these patients. METHODS: Of 142 patients, who presented to the Bipolar Disorder Unit of Zonguldak Karaelmas University Research and Application Hospital between the dates of August 1, 2008 and June 31, 2009 and diagnosed with BMD according to DSM-IV criteria consecutively, 118 patients signed informed consent and 90 of them completed the study. They all were in euthymic phase during the study evaluations. A sociodemographical data form, Wender-Utah Rating Scale (WURS), ADD/ADHD Diagnostic and Evaluation Inventory for Adults, and Structural Clinical Interview for DSM-IV Axis I Disorders, Clinical Version (SCID-I) were applied to all participating patients. RESULTS: A total of 23.3% of all patients met the criteria for A-ADHD diagnosis along BMD. No difference was detected regarding sociodemographical features between the BMD+A-ADHD and the BMD without A-ADHD groups. The BMD+A-ADHD group had at least one extra educational year repetition than the other group and the difference was statistically significant. The BMD starting age in the BMD+A-ADHD group was significantly earlier (p=0.044) and the number of manic episodes was more frequent in the BMD+A-ADHD group (p=0.026) than the BMD without ADHD group. Panic disorder in the BMD+A-ADHD group (p=0.019) and obsessive-compulsive disorder in the BMD+C-ADHD group (p=0.001) were most frequent comorbidities. CONCLUSIONS: A-ADHD is a frequent comorbidity in BMD. It is associated with early starting age of BMD, higher number of manic episodes during the course of BMD, and more comorbid Axis I diagnoses.

Sleep disorders in Behçet's disease, and their relationship with fatigue and quality of life.

Behçet's disease, a systemic vasculitis, can cause varying degrees of activity limitation, fatigue and quality of life impairment. To date, there have been no studies regarding sleep disturbance and its relationship with fatigue and life quality in Behçet's disease. We aimed to evaluate sleep disorders and polysomnographic parameters, and to determine their relationship with fatigue and quality of life in Behçet's disease. Fifty-one patients with Behçet's disease without any neurological involvement were interviewed regarding sleep disorders. Twenty-one subjects with no sleep complaints were included as the control group. Sleep-related complaints were evaluated in a face-to-face interview. Sleep quality, excessive daytime sleepiness, fatigue, depression, anxiety, disease activity/severity, and quality of life questionnaires and an overnight polysomnography were performed. Prevalences of restless legs syndrome (35.3%) and obstructive sleep apnea syndrome with/without other sleep disorders (32.5%) were higher than in the control group and the general population. Fatigue was higher in patients with restless legs syndrome and obstructive sleep apnea syndrome, and in those with lower minimum oxygen saturation; hence, only patients with restless legs syndrome had quality of life impairment. Sleep efficiency index and sleep continuity index were lower, and wake after sleep onset, respiratory disturbance index and apnea-hypopnea index were higher than in controls (P < 0.01). Neither sleep disorders nor polysomnographic parameters were related to disease activity and severity. In conclusion, it is important to question sleep disorder followed by a polysomnography, if necessary, in order to improve quality of life and fatigue in Behçet's disease.

Antipsychotic prescriptions in a university hospital outpatient population in Turkey: a retrospective database analysis, 2005-2006.

OBJECTIVE: The aim of this study is to document the sociodemographic and the clinical profile of patients who are on antipsychotic (AP) medication prescribed in outpatient mental health clinic of a university hospital. METHODS: A retrospective chart review was conducted for all outpatient files between 2005 and 2006 at the Zonguldak Karaelmas University, Medical Faculty Hospital, Department of Psychiatry in Turkey. All patients prescribed AP with regular follow up were recruited for the study. The type of AP and the route of administration were recorded. The diagnosis, age and gender of the patients were also evaluated. RESULTS: We reviewed 1606 patients' files. APs were prescribed in 27.6% of the patients. Atypical antipsychotics (AAPs) represented 75.1% and typical antipsychotics (TAPs) represented 24.9% of all antipsychotic prescriptions in our study. The main psychiatric diagnoses associated with a TAP prescription were: psychotic disorders (6.5%), major affective disorders (49.5%), anxiety disorders (36.4%), and other psychiatric diseases (7.4%). The main psychiatric diagnoses associated with an AAP prescription were: psychotic disorders (35.1%), major affective disorders (31.1%), anxiety disorders (27.8%), somatoform disorders (2.4%) and other psychiatric diseases (6.4%). Twenty-eight of these patients (6.3%) were prescribed more than one AP, 45 patients were prescribed mood stabilizer (10.2%) and 272 patients were prescribed antidepressant agents (61.2%) in addition to AP. CONCLUSIONS: The results reflect the particular use of AAPs in present study population. In line with the published data, the results of this study show that AAPs and TAPs are widely used in those with major affective disorders and psychotic disorders. These findings also underline the widespread off-label use of APs in the treatment of other psychiatric disorders.

A review of liver function tests during treatment with atypical antipsychotic drugs: a chart review study.

OBJECTIVE: Atypical antipsychotic drugs commonly cause asymptomatic increase in the liver enzymes and serum bilirubin levels. However they rarely may induce a serious hepatic toxicity. In this article we aimed to evaluate the effect of atypical antipsychotic drugs namely olanzapine, risperidone and quetiapine on the hepatic enzymes and serum bilirubin levels in psychiatric patients. METHOD: Chart reviews of 312 patient followed-up at Psychiatry Department of Zonguldak Karaelmas University Hospital were examined in detail. The patients whose baseline and follow-up liver function tests including alanine aminotransfeaminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alkaline phosphotase (ALP) and serum bilirubin that were measured before and within the treatment period of first and sixth months were enrolled. Forty eight males and 62 females whose ages ranging from 12 to 65 years were eligible for this study (no pregnant case was present). RESULTS: The repartition according to treatment is as follows: olanzapine (n=33), risperidone (n=29), and quetiapine (n=48). Two of the 110 patients (1.8%) presented with increased AST levels of up to 4 fold and ALT of thrice the basal level and needed to stop treatment (AST increase in one female with olanzapine 20 mg/day; ALT increase in one male with olanzapine 30 mg/day). Thirty of the 110 patients (27.2%) showed asymptomatic increases in ALT, AST, GGT and serum bilirubin levels in the first month of the study. After 6 months of the treatment, abnormalities in the liver function tests were observed in 25 patients (22.7%). CONCLUSION: These results were in accordance with previous studies that asymptomatic increase of liver enzymes are common but significant liver enzyme elevations are rare during atypical antipsychotic treatment. We suggest that obtaining baseline liver enzyme tests before atypical antipsychotic therapy and monitoring regularly specifically in patients with risk factors for liver damage during therapy.

Psychopathology, depression and dissociative experiences in patients with lichen simplex chronicus.

OBJECTIVE: Psychogenic factors may play a contributory role in the development or persistence of lichen simplex chronicus (LSC). The objective of this study was to evaluate the psychiatric profile of patients with LSC including depression and dissociative experiences. METHOD: Dermatology outpatients with a LSC (n=30) were compared with outpatients with tinea in which psychological factors are regarded as negligible (n=30). All subjects were given psychiatric scales including the Symptom Checklist-90-Revised (SCL-90-R), Hamilton Rating Scale for Depression (HAM-D) and Dissociative Experience Scale (DES). RESULTS: All mean SCL-90 scores for general psychopathology were higher in the LSC compared to the control group. HAM-D and DES scores were significantly higher in the LSC group (P<.05) as well. In addition, the number of patients whose total DES score of 30 and above was higher in the LSC group. CONCLUSIONS: Psychiatric symptoms appear relatively common among patients with LSC. Further research is needed to confirm the possible role of dissociative tendencies in the etiology of LSC.

[Validation of the Turkish version of the mood disorder questionnaire for screening bipolar disorders]. / Duygudurum Bozukluklari Olçegi'nin Türkçe Uyarlamasiniin Bipolar Bozukluk Taramasinda Geçerligi.

OBJECTIVES: The aims of the study were to validate the Turkish version of the Mood Disorder Questionnaire (MDQ) as a screening tool and to determine its optimum cut-off value for bipolar disorder. METHODS: Validation of the Turkish version of the MDQ was conducted on a sample of 309 consecutive patients who attended the psychiatry outpatient unit of 2 different university hospitals. The Structured Diagnostic Interview for DSM-IV Axis I Disorders (SCID) was used as a gold standard test and receiver operating characteristic (ROC) analysis was used to evaluate test performance of the MDQ. RESULTS: In all, 36 (11.7%) patients received a diagnosis of bipolar disorder (type I and II, and bipolar disorder not otherwise specified), 185 (86.1%) were diagnosed as having at least one Axis I psychiatric disorder other than bipolar disorder, and 7 (2.2%) had no psychiatric disorder according to SCID results. Sensitivity and specificity results indicated that the best Turkish MDQ cut-off point was 7 (sensitivity: 0.64; specificity: 0.77), the cut-off point 5 had 0.81 sensitivity and 0.53 specificity, and the cut-off 6 had 0.75 sensitivity and 0.63 specificity. CONCLUSION: The Turkish MDQ has satisfactory psychometric properties for screening bipolar disorder. The psychometric properties of the Turkish MDQ and its ease of use make it a useful tool for screening bipolar disorders, though further population-based research is required to confirm these results.

Frontotemporal hypoperfusion detected by 99mTc HMPAO SPECT in a patient with olfactory reference syndrome.

Olfactory reference syndrome (ORS) is a rare psychiatric condition with an unclear etiology showing great interindividual variance in its course and treatment response. Although the core symptom of the disease is preoccupation with imagined body odor that persists despite reassurance, clinical presentations mimic various psychiatric illnesses. There have been several case reports of underlying general medical conditions related to ORS, such as epilepsy, arteriovenous malformation and substance abuse. However, to our knowledge, there has been no report on regional blood flow changes detected in patients with ORS. In this brief report, we present the case of a patient with ORS who underwent unnecessary surgery and was referred twice by surgeons. The phenomenology, nosological features and differential diagnosis of ORS are also discussed with regard to its relationship with affective disorders.

Open-label study of adjunct modafinil for the treatment of patients with fatigue, sleepiness, and major depression treated with selective serotonin reuptake inhibitors.

Despite the efficacy of selective serotonin reuptake inhibitors (SSRIs) in the treatment of major depression, a significant number of patients show partial or no remission of symptoms. Some evidence suggests that psychostimulant augmentation may be helpful in treating patients with residual symptoms of depression. The efficacy of modafinil in augmenting SSRIs in depressed patients with residual fatigue or excessive daytime sleepiness has yet to be systematically investigated. In a series of 25 patients with major depressive disorder, according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, who showed significant residual symptoms after an adequate SSRI trial (12 wk) and who were evaluated according to the Fatigue Severity Scale (FSS), subjects with scores > or = 4 were given open-label modafinil augmentation for a minimum of an additional 6 wk. Treatment response was assessed prospectively with the FSS, the Epworth Sleepiness Scale (ESS), and the Hamilton Rating Scale for Depression (HAM-D) during the first visit and at the second and sixth weeks. Twenty-one of 25 patients in this series who were treated with modafinil and SSRIs completed the 6-wk augmentation trial. At end-point assessment, all patients showed significant improvement in fatigue and sleepiness in FSS and ESS scores, as well as in HAM-D scores (P<.01). In the second week, 29.4% of patients had a HAM-D score <7, which was defined as remission; this rate was 64.7% in the sixth week. The rate of patients whose HAM-D score dropped by more than 50%, defined as responders to treatment, was 41.1% and 76.4% in the second and sixth weeks, respectively. Results of this preliminary, open-label trial suggest that modafinil may be effective in augmenting ongoing SSRI treatment for a portion of patients with major depression who have residual fatigue and sleepiness. Larger, placebo-controlled trials appear warranted to investigate the clinical efficacy and tolerability of modafinil augmentation of SSRI treatment in these patients.

Childhood trauma and suicide risk in the population living in Zonguldak Province.

INTRODUCTION: No previous study has investigated the association between early trauma and suicidal behavior in Zonguldak. The aim of this study was to investigate the incidence of childhood abuse and neglect in the general population living in Zonguldak province and the relationship between childhood trauma and suicidal ideations and attempts. METHODS: The present study was carried out with 897 people in the general population, as assessed in a representative sample from Zonguldak province. The cluster sampling method was used. After obtaining written consent from the people who agreed to participate in the study, the Socio-demographic Information Form, Suicide Probability Scale, Childhood Trauma Questionnaire, Beck Depression Inventory, and Beck Anxiety Inventory were administered. RESULTS: The lifetime prevalence of suicidal ideations was 18.3% among those who experienced at least one type of early trauma, and it was 9.6% among those without a history of childhood trauma (P < 0.001). Only emotional abuse exhibited a significantly high odds ratio for lifetime suicidal ideations (odds ratio [OR] = 3.168, 95% confidence interval [CI] = 1.731-5.798) and attempts (OR = 3.467, 95% CI = 1.343-8.952). Emotional neglect showed a high odds ratio only for lifetime suicidal attempts (OR = 3.282, 95% CI = 1.287-8.371). There were significant correlations among the Beck Depression Inventory, Beck Anxiety Inventory, and Suicidal Probability Scale sub-scores and all six Childhood Trauma Questionnaire scores. DISCUSSION: Emotional abuse and neglect in childhood are significantly associated with lifetime suicidal ideations and attempts in the general population living in Zonguldak province. Therefore, clinicians should be aware of the importance of the childhood trauma in the patients with suicidal ideations and attempts.

Evaluation of the hippocampus and the anterior cingulate gyrus by proton MR spectroscopy in patients with post-traumatic stress disorder.

PURPOSE: Previous studies have shown that post-traumatic stress disorder (PTSD) is associated with lymbic system dysfunction. The purpose of this study is to evaluate whether or not the neuronal integrity in hippocampus and anterior cingulate gyrus is affected in PTSD as assessed by proton magnetic resonance spectroscopy. MATERIALS AND METHODS: Single voxel MRS was performed in 10 PTSD patients and 6 healthy subjects in two cerebral areas highly involved in the pathophysiology of PTSD (the hippocampus and the anterior cingulate gyrus). Spectra were obtained using PRESS sequence. Voxel sizes were 3.7 cm3 (hippocampus) and 6-7.2 cm3 (anterior cingulate gyrus). Metabolite ratios of NAA/Cr and Cho/Cr were calculated and compared to the control subjects. The severity of PTSD in the patient group was evaluated by Clinician-Administered PTSD Scale. RESULTS: Analysis of the proton MR spectra showed reductions in NAA/Cr ratio in bilateral hippocampus of PTSD subjects as compared to normal controls (p < 0.001), whereas Cho/Cr ratios were increased (p < 0.001). Reductions in NAA/Cr ratio were found in the the anterior cingulate gyrus of PTSD subjects as compared to normal controls (p < 0.01), whereas Cho/Cr ratios did not differ significantly (p > 0.05). CONCLUSION: Changes in the metabolite ratios provide support for either neuronal dysfunction or neuronal loss both in the hippocampus and the anterior cingulate gyrus and may be associated with reduced neuronal integrity. Further studies with MRS in larger patient populations are needed to clarify the relationship between brain structures and neurobiology of PTSD.

The Relationship between Quality of Life and Cognitive Functions, Anxiety and Depression among Hospitalized Elderly Patients.

OBJECTIVE: Older people seek not only a longer life, but also a better quality of life (QOL). Our aim was to find out the relationship between QOL and socio-demographic factors, social activities, cognitive status, depression and anxiety symptoms among medically ill and hospitalized elderly people in Turkey. METHODS: Two hundred forty three patients age 65 years or older were examined. The Socio-demographic Data Survey, the Mini Mental State Examination (MMSE), the Geriatric Depression Scale-short form (GDS-15), the Beck Anxiety Inventory (BAI) and the World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-OLD) were applied to participants. The independent samples t-test and analysis of variance (ANOVA) were used to analyze quantitative data. Pearson's correlation and linear regression analysis were performed. RESULTS: The total score for QOL was significantly higher for those who saw their family members and relatives frequently rather than rarely (p=0.002), who were always busy with social activities rather than rarely or never (p<0.001), who had more years of education (p=0.003), and who were frequently exercising (p=0.023). According to linear regression analysis, the WHOQOL-OLD total score increased by 0.295 and -0.936 units, while MMSE and GDS-15 scale scores increased one unit respectively (ß=0.295, t=1.979, p=0.04; ß=-0.936, t=-4.881, p<0.001). CONCLUSION: Cognitive disabilities, depression, and other psychiatric problems along with medical disease negatively affect the QOL of elderly patients. While performing medical assessment regarding elders, detecting and treating cognitive disabilities and depression is very valuable in improving the QOL of elderly patients.

The Effect of Dressing Styles and Attitudes of Psychiatrists on Treatment Preferences: Comparison between Patients and Psychiatrists.

INTRODUCTION: Recently, different dressing styles and attitudes of psychiatrists have been proposed to enhance the interaction between patients and the physician. The aim of the present study was to investigate the preferences of dressing style and attitudes of a psychiatrist of the patients referred to an outpatient psychiatry clinic and the perception of psychiatrists regarding the preferences of the patients. METHODS: One hundred and fifty-three patients referred to the outpatient psychiatry clinic of the Bülent Ecevit University School of Medicine, and 94 psychiatrists have been included in the present study. RESULTS: When the images of psychiatrists were evaluated in terms of referral for treatment, trust in treatment, and willingness to share their confidential matters, both groups gave minimum scores to causal/sports dress style. While psychiatrists preferred to dress in a suit, casuals, and white coat, the preference order was white coat, casual dress, and suit in the patient group. There was a significant difference between the groups with respect to three dressing styles. CONCLUSION: It can be suggested that psychiatrists assume that patients are traditional in terms of their preference of the dressing style of a doctor and doctor-patient relationship, and a white coat is important to enhance the treatment adherence of patients.

Acute dystonia during pegylated interferon alpha therapy in a case with chronic hepatitis B infection.

Interferon (IFN) is the most widely prescribed drug of choice for chronic hepatitis B infection, which is a common health problem in our country. Therapy with IFN-alpha may be associated with a number of neuropsychiatric symptoms, such as Parkinsonism, akathisia, seizure, and depressive disorders. In this case report, we present clinical and laboratory findings of a case with chronic hepatitis B that developed acute dystonia soon after the first dose of pegylated interferon alpha. As far as we know, this is the first report in English literature indicating such an adverse effect of pegylated interferon alpha.

Relationship of Cognitive Functions with Daily Living Activities, Depression, Anxiety and Clinical Variables in Hospitalized Elderly Patients.

INTRODUCTION: Cognitive impairment in elderly patients, which may be a sign of dementia, depression, anxiety or medical diseases, has been determined as a risk factor for functional loss. In this study, we aimed to investigate the frequency of cognitive impairment and to investigate the relationship of cognitive status with sociodemographic variables, daily living activities, anxiety and depression in elderly inpatients. METHOD: The sample of this cross-sectional and descriptive study consists of 243 patients aged 65 years and older who were hospitalized in Bülent Ecevit University Hospital. A sociodemographic questionnaire,, the Mini-Mental State Examination (MMSE), Activities of Daily Living Scale, Lawton-Brody Instrumental Daily Activities Scale, Geriatric Depression Scale (GDS) and the Beck Anxiety Inventory were used for data collection. RESULTS: One hundred and six (43.6%) patients were female and 137 (56.4%) were male. The patients were divided into two groups according to the Mini-Mental State Examination (MMSE) 23/24 cut-off score. The cognitive decline was statistically significantly more frequent in patients who were older, female, less educated, low socioeconomic status, and living in rural areas. There were more problems in the basic and instrumental activities of daily living and nutrition in patients with cognitive decline. Anxiety and depression scores were higher in this group. In our study, although the frequency of cognitive decline and depression according to GDS were 56% and 48%, respectively; we found that only 10.5% of patients applied to the psychiatrist, and 9.3% of patients received psychiatric treatment. CONCLUSION: Cognitive decline may cause deterioration in the daily living activities, nutrition and capacity for independent functioning. Older age, female, low education, low socioeconomic status and living in rural area are important risk factors for cognitive impairment. Cognitive decline in older age may be associated with depression and anxiety. We assume that when cognitive decline, depression and other psychiatric problems are unidentified, it may contribute to deterioration of mental health in medically ill elderly.

Pain perception in patients with bipolar disorder and schizophrenia.

OBJECTIVE: Pain perception is reported to be altered in patients with depression and schizophrenia. However, few studies have investigated the pain perception in patients with bipolar disorders. We therefore aimed to compare pain sensitivity between patients with bipolar disorder, schizophrenia and controls. METHODS: Study groups consisted of 30 patients with bipolar disorder, and control groups consisted of 27 patients with schizophrenia and 59 healthy subjects. Pain perception was assessed with cold pressor test (CPT) by exposure to ice-water. RESULTS: Patients with schizophrenia had significantly higher pain thresholds (PTh) than patients with bipolar disorder. There were no differences between the PTh of patients with schizophrenia and healthy control subjects. However, patients with bipolar disorder had significantly lower pain tolerance (PT) in the CPT than patients with schizophrenia and corresponding healthy control subjects. CONCLUSIONS: The higher PTh in the schizophrenia group compared with the bipolar group found in this study supports further investigation of a potential difference in the pain perception between patients with schizophrenia and bipolar disorder. Theoretical implications of these findings and possible relevant behavioural and neurochemical mechanisms are discussed.
