RESUMO
The aim of this study was to investigate the relationships among childhood trauma, dissociative experiences, and internet gaming disorder (IGD) in young adults diagnosed with attention deficit hyperactivity disorder (ADHD) and age- and gender-matched controls. Forty participants diagnosed with ADHD at a university hospital psychiatric outpatient clinic and 40 healthy controls completed a test battery that included a sociodemographic form as well as the Adult ADHD Severity Rating Scale (ASRS), Childhood Trauma Questionnaire (CTQ), Dissociative Experiences Scale (DES), Somatoform Dissociation Questionnaire (SDQ), and Internet Gaming Disorder Scale - Short Form (IGDS9-SF). The CTQ (t = -4.61, p < .01), DES (t = -4.71, p < .01), SDQ (t = -2.40, p < .01), and IGDS9-SF (t = -4.89, p < .01) scores were significantly higher in the ADHD group than in the control group. A hierarchical regression analysis that explained 50% of unique variance in internet gaming disorder (IGD) indicated that being male (ß = 0.41, t = 4.61, p < .001) and having an ADHD diagnosis (ß = 0.48, t = 5.49, p < .001) are robust predictors. Additionally, the DES score, which indicates the severity of psychoform dissociation (ß = 0.34, t = 2.43, p = .017), was found to be significantly associated with IGD after controlling for ADHD diagnosis and childhood trauma. While excessive gaming may increase dissociative symptoms, the mental state of dissociative experiences may be a predisposing factor for IGD; however, further studies are needed to investigate these claims.

Childhood trauma and dissociative experiences are suggested to be predisposing transdiagnostic factors for attention deficit /hyperactivity disorder (ADHD) as well as many psychiatric disorders. Trauma-related symptoms such as motor restlessness, emotional instability, and concentration problems can mimic, trigger, or exacerbate ADHD symptoms. Moreover, given the relationship between ADHD and trauma-induced distress, it has been suggested that dissociative experiences and attention problems may reveal overlapping characteristics. The aim of this study was to investigate the associations between dissociative experiences and attention deficits by carrying out mixture analysis. A thousand and thirty-seven participants volunteered to the online investigation. Participants completed a test battery that included a sociodemographic form as well as the Adult ADHD Severity Rating Scale (ASRS), Wender Utah Rating Scale (WURS), Childhood Trauma Questionnaire (CTQ), Dissociative Experiences Scale (DES), and Somatoform Dissociation Questionnaire (SDQ). Item responses on the DES and attention deficit symptoms as indexed by the ASRS were subjected to latent class analysis. The three-latent-class model outperformed alternative mixture models. Mixture analysis classified the sample into three homogenous subgroups as follows: (1) No/low dissociation or attention problems; (2) Moderate dissociation with attention problems; and (3) High dissociation with attention problems. High dissociators with attention problems were characterized by heightened scores on somatoform dissociation and emotional neglect. No/low dissociation or attention problems latent class reported significantly lower scores on hyperactivity/impulsivity, depression, attention deficit in childhood, and sexual abuse than both moderate and high dissociation latent classes. High dissociators and moderate dissociators significantly differed on conduct problems and physical abuse. We concluded that impulsive hyperactivity, depression, and childhood sexual abuse were common features in heightened dissociation latent classes, as well as attention deficit.
RESUMO
PURPOSE: Individuals can generally be divided into morning, neither and evening types according to behavioral, psychological, and biological variables including appetite levels, usual meal times, sleep times, and melatonin secretion. These factors together identify a person as being part of a certain chronotype, i.e., as feeling more efficient either in the morning (morning type) or later in the day (evening type). Food addiction is defined as addictive behavior toward palatable foods and is thought to be one of the underlying risk factors for obesity. Our aim in this study was to investigate the relationship between circadian rhythm differences and food addiction via insomnia and impulsivity in university students. METHOD: Participants were 1323 university students, filled out a package of psychological tools, including the Morningness-Eveningness Questionnaire, Insomnia Severity Index, Barratt Impulsiveness Scale Short Form, and Yale Food Addiction Scale. Logistic regression analysis was used to investigate direct relation of food addiction with insomnia, impulsivity and obesity, and mediation regression analysis was used to investigate the indirect effect of circadian rhythm differences on food addiction. RESULTS: Our findings indicated that evening types were more prone to insomnia and impulsivity, and also insomnia and impulsivity significantly contributed to the variance of food addiction. Although there was no significant linear relationship between circadian rhythm differences and food addiction, evening-type circadian preferences were indirectly associated with higher food addiction scores mediated by insomnia and impulsivity. CONCLUSION: The most remarkable result of our work was that circadian rhythm differences seem to indirectly effect on food addiction through elevated insomnia and impulsivity. LEVEL OF EVIDENCE: Level V, descriptive cross-sectional survey.

OBJECTIVE: The Western-type diet is associated with an elevated risk of Alzheimer's disease and other milder forms of cognitive impairment. The aim of the present study was to investigate the effects of the environmental enrichment on amyloid and tau pathology in high-fat and high-sucrose-fed rats. METHODS: In total, 40 adult male rats were categorised into two main groups according to their housing conditions: enriched environment (EE, n=16) and standard housing condition (n=24). The groups were further divided into five subgroups that received standard diet, high-fat diet, and high-sucrose diet. We performed the analysis of amyloid ß-peptide (Aß) (1-40), Aß(1-42), amyloid precursor protein (APP), and tau levels in the hippocampus of rats that were maintained under standard housing conditions or exposed to an EE. RESULTS: The EE decreased the Aß(1-40), Aß(1-42), APP, and tau levels in high-fat and high-sucrose-fed rats. CONCLUSION: This observation shows that EE may rescue diet-induced amyloid and tau pathology.

OBJECTIVE: Sleep is one of the most significant of human behaviors, occupying roughly one third of human life. Sleep is a process the brain requires for proper functioning. Sleep hygiene can be described as practices to ease sleep and to avoid factors which decrease sleep quality. Inadequate sleep hygiene generally results in disturbance of daily life activities due to inability to sustain sleep quality and daytime wakefulness. Therefore, the importance of development and utilization of measures of sleep hygiene increases. The aim of the study was to assess psychometric properties of the Sleep Hygiene Index (SHI) in clinical and non-clinical Turkish samples. METHOD: Data were collected from 106 patients with major depression consecutively admitted to the psychiatry clinic of Yüzüncü Yil University School of Medicine and 200 were volunteers recruited from community sample who were enrolled at the university. The SHI, Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI) and Epworth Sleepiness Scale (ESS) were administered to the subjects. Factor structure of the SHI was evaluated with explanatory and multi-sample confirmatory factor analyses. Pearson product-moment correlation coefficients of the SHI with the PSQI, ISI and ESS were computed. Item analyses, internal consistency coefficients and intra-class correlations between two repeated applications in both patient and healthy subjects were calculated. RESULTS: The SHI revealed a unidimensional factor structure. Significant strong partial associations of the SHI with depression, insomnia and poor sleep quality and a modest partial association with sleepiness were detected. Cronbach's alphas for the SHI in community sample and patients with major depression were 0.70 and 0.71, respectively. Additionally, we found acceptable three-week temporal reliability in terms of intra-correlation coefficients of r=0.62, p<0.01 for the community sample and of r=0.67, p<0.01 among patients with major depression. CONCLUSION: The SHI revealed adequate validity and reliability to be used by researchers in Turkish sample. Current results were discussed in light of previous findings and theoretical considerations.

OBJECTIVE: There are limited comparative studies on classic and new-generation antihistamines that affect sleep quality and mood. The purpose of this study was to determine and compare the effects of classic and new-generation antihistamines on sleep quality, daytime sleepiness, dream anxiety, and mood. METHODS: Ninety-two patients with chronic pruritus completed study in the dermatology outpatient clinic. Treatments with regular recommended therapeutic doses were administered. The effects of antihistaminic drugs on mood, daytime sleepiness, dream anxiety, and sleep quality were assessed on the first day and 1 month after. RESULTS: Outpatients who received cetirizine and hydroxyzine treatments reported higher scores on the depression, anxiety, and fatigue sub-scales than those who received desloratadine, levocetirizine, and rupatadine. Pheniramine and rupatadine were found to be associated with daytime sleepiness and better sleep quality. UKU side effects scale scores were significantly elevated among outpatients receiving pheniramine. Classic antihistamines increased daytime sleepiness and decreased the sleep quality scores. New-generation antihistamines reduced sleep latency and dream anxiety, and increased daytime sleepiness and sleep quality. CONCLUSION: Both antihistamines, significantly increased daytime sleepiness and nocturnal sleep quality. Daytime sleepiness was significantly predicted by rupadatine and pheniramine treatment. Cetirizine and hydroxyzine, seem to have negative influences on mood states. Given the extensive use of antihistamines in clinical settings, these results should be more elaborately examined in further studies.

BACKGROUND: This study aims to conduct the first-ever evaluation of our previously proposed behaviors of "hemomania" in individuals engaged with nonsuicidal self-injury (NSSI). METHODS: The study encompassed 130 outpatients engaged with NSSI who applied at the psychiatry outpatient clinic. NSSI behaviors were assessed using the Inventory of Statements About Self-Injury, while psychiatric diagnoses were evaluated using the Structured Clinical Interview for DSM-5 Disorders-Clinician Version. Subsequently, participants completed the Depression Anxiety Stress Scale-21 and Short Form of Barratt Impulsiveness Scale. RESULTS: The prevalence of at least one hemomania behavior including seeing blood, tasting blood, bloodletting, and blood-drinking was observed to be 43.1% in individuals with NSSI. When participants were divided into two groups, individuals with hemomania exhibited: (1) a higher incidence of psychiatric comorbidities, increased suicide attempts, and more severe symptoms of depression, anxiety, stress, and impulsivity, (2) higher comorbidity rates of borderline personality disorder, body-focused repetitive behaviors, and dissociative disorders, and (3) elevated frequencies of certain NSSI behaviors, including cutting, biting, needle-ticking, and carving, compared to those without. CONCLUSION: Hemomania could be considered a specific impulse control disorder, characterized by heightened impulsivity and a persistent urge to obtain one's own blood. However, further studies are needed to validate this hypothesis.

OBJECTIVE: Seasonality is one of the most interesting but still elusive issue in suicide research. Linkages of seasonality in suicides to possible contributors such as gender, type of method used, and climatic factors have received attention in different cultures. We aimed at evaluating seasonal trends in suicidal behaviour according to demographic characteristics, reasons for self-destructive behaviour and means preferred in suicide. METHODS: Our aim was to assess the seasonal variation in self-destructive behaviour in terms of completed and attempted suicides in a 3-year time period from 2008 to 2010 in Van, Turkey. A total of 1448 cases were registered over a 3-year time period in the city. Seasonal deviations in demographic characteristics, reasons for suicide, and methods of suicide were evaluated. RESULTS: Seasonal distribution of both completed and attempted suicides by gender did not significantly deviate. On the other hand, we found a significant decline in self-destructive behaviours among those who were single and student in the spring. We found a peak in self-destructive behaviours in the autumn among Individuals who suffer from psychological problems. CONCLUSIONS: Subjects with psychological difficulties were more prone to commit suicide in autumn. Seasonal differences in methods of suicide used by suicidal subjects were not significant.

OBJECTIVE: Society's sleep-wake cycle and eating behaviors have altered and are considered the psychological outcomes of the coronavirus disease-2019 (COVID-19) pandemic. Our aim was to examine the relationship between sleep-wake rhythms, eating behaviors (dieting, oral control, and bulimic behaviors), and attention deficit hyperactivity disorder (ADHD) symptoms with weight gain during the COVID-19 pandemic. METHODS: The participants were 578 female university students divided into three groups based on weight change during COVID-19 who lost weight, whose weight did not change (nWC), and who gained weight (WG). The participants' information about weight change in the last year and responses to the Pittsburg Sleep Quality Index, Eating Attitudes Test, Adult ADHD Severity Rating Scale, and Wender Utah Rating Scale were collected via an online survey from January 8, 2021 to January 11, 2021. RESULTS: The sleep-wake phase was more delayed in WGs than in the other two groups. The bulimic behavior score was higher and the oral control behavior score was lower in the WG group than in the nWC group. A hierarchical regression analysis model, in which weight change scores were dependent variables, showed that mid-sleep time in second step (ß=4.71, t=2.18, p=0.03), and oral control (ß=-0.11, t=-3.24, p=0.001)/bulimic behaviors (ß=0.20, t=3.20, p=0.001) in third step were associated with weight change after controlling for both current and childhood ADHD symptoms. CONCLUSION: Chronotherapeutic approaches that regulate sleep-wake rhythm may facilitate weight control of individuals during stressful periods, such as the COVID-19 outbreak.
RESUMO
OBJECTIVE: There is mounting evidence indicating that oxidative and inflammatory processes may have an important role in the pathogenesis of panic disorder (PD). PD is a heterogeneous disease, and panic attacks are divided according to the different symptom clusters as respiratory, nocturnal, non-fearful, cognitive, or vestibular subtypes. The aim of this study was to compare whole-blood and serum superoxide dismutase (SOD), glutathione peroxidase and adenosine deaminase activities in PD patients with/without nocturnal, respiratory subtypes and healthy subjects. METHODS: The study was conducted including 60 patients with PD and 30 healthy control subjects. The Panic Attack Symptom Checklist, Panic and Agoraphobia Scale, Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale were administered to the patients. Biochemical analyses were performed after all the blood samples were collected. RESULTS: We found that whole-blood SOD and glutathione peroxidase activities of patients were significantly lower and adenosine deaminase activities of patients were higher than those of healthy controls. There were no statistically significant differences between respiratory and nocturnal subtypes. In addition, there were no marked relationships between the duration of illness and panic-agoraphobia scores of patients with nocturnal subtypes. Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale scores of patients with the nocturnal subtype were markedly higher than those of patients without the nocturnal subtype. CONCLUSION: The results suggest that oxidative and inflammatory processes may play a role in the pathophysiology of PD. These findings may support the idea that both nocturnal and respiratory subtypes of PD have different symptom clusters of the same disease.

OBJECTIVE: Previous studies have indicated that obsessive compulsive disorder (OCD) is associated with childhood traumatic experiences and higher levels of dissociation. Dissociative tendency may arise when individual attempt to incorporate adverse experiences into cognitive schema. METHODS: We investigated the possible links among childhood trauma, dissociation, and cognitive processes. We evaluated 95 patients with OCD using the Beck Depression Inventory (BDI), Thought-Action Fusion Scale (TAFS), Metacognitions Questionnaire (MCQ-30), White Bear Suppression Inventory (WBSI), Dissociative Experiences Scale (DES), and Childhood Trauma Questionnaire (CTQ-28). RESULTS: The CTQ-28 total scores were not associated with Y-BOCS total, Y-BOCS insight, BDI, TAFS, MCQ-30, and WBSI scores. The TAFS Total, MCQ-30, WBSI, and BDI scores were significantly associated with DES scores. Regression analysis revealed that MCQ-30 and WBSI scores significantly predicted the DES scores. CONCLUSIONS: These results suggest that in spite of pathological connotation of dissociative experiences, dissociation may primarily constitute a cognitive trait which is strongly associated with cognitive processes.

BACKGROUND: There is an increasing interest about the role of miRNAs in the pathogenesis of bipolar disorder (BD). In this study, we aimed to examine the role of miRNAs as potential diagnostic and clinical biomarkers in BD. METHODS: Fifteen miRNAs in plasmas obtained from BD patients (n = 66) and from the healthy control group (n = 66) were analyzed by a qPCR test. Clinical variables including lithium treatment response were assessed with various test batteries. The correlation of the miRNA levels with the clinical variables and scale scores was examined. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed using the DIANA-miRPath v.3.0 software to identify the possible target genes. RESULTS: The miR-132, miR-134, miR-152, miR-607, miR-633, and miR-652 levels were significantly increased, whereas the miR-15b and miR-155 levels were found to be significantly decreased in the patient group compared to the controls. The miR-15b-5p and miR-155-5p levels and increases in the miR-134-5p and miR-652-3p levels were calculated to have 83.3 % sensitivity and 78.8 % specificity in determining the risk of BD. miR-155-5p was associated with the disease burden and severity. Fatty acid biosynthesis and metabolism, viral carcinogenesis, the EBV infection, and extracellular matrix and adhesion pathways were highlighted as target pathways. CONCLUSION: We can conclude that miRNAs may play a role in the pathophysiology of BD through various biological pathways and that miRNAs may be used as a screening test to distinguish bipolar patients from healthy controls. Our findings will provide a basis for long-term follow-up studies with larger samples.

OBJECTIVE: The aim of the present study was to investigate the relationship between nightmares and acute myocardial infarction (AMI) occurring during sleep, and also to evaluate the influence of several related factors. METHOD: The sample comprised AMI patients who had been admitted to the coronary care unit. The patients were grouped into two categories; the asleep-AMI group consisted of 36 patients who had the onset of symptoms of AMI during sleep, and the awake-AMI group included 183 patients who had AMI while they were awake. The sleep quality and dream anxiety for the 1-month interval before AMI were assessed with Pittsburgh Sleep Quality Index (PSQI) and Van Dream Anxiety Scale (VDAS), respectively. RESULTS: Asleep-AMI patients reported significantly poorer subjective sleep quality, significantly higher global PSQI scores, and displayed significantly higher nightmare frequency, difficulty in falling asleep after a nightmare, higher autonomic hyperactivity, dream recall frequency, daytime anxiety, psychological problems, and higher global dream anxiety scores than awake-AMI patients. CONCLUSION: The present study suggests that sleep anxiety and related emotions are associated with AMI during sleep.

OBJECTIVE: To investigate the comparative efficacy of aripiprazole and risperidone as augmenting agents in the treatment of obsessive-compulsive disorder (OCD) patients who did not show a ≥35% decrease in the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) after 12-week monotherapy with selective serotonin reuptake inhibitors (SSRIs). METHODS: The study consists of two different periods of treatment: a 12-week prospective period to determine resistance to SSRI treatment and an 8-week single-blind addition period for refractory patients only. Ninety patients were randomly assigned to receive one of the SSRI treatments. Sixty-nine patients (76.6%) completed the 12-week SSRI monotherapy period. Forty-one patients (59.4%) were considered refractory and were randomised to receive either risperidone (20 patients, 3 mgr daily) or aripiprazole (21 patients, 15 mgr daily) as augmentation to SSRI treatment. Sixteen patients (76.2%) in the aripiprazole group and 18 patients (84%) in the risperidone group completed the 8-week treatment period. RESULTS: Eight patients (50%) in aripiprazole and 13 patients (72.2%) in risperidone group met response criteria of Y-BOCS decrease ≥35% at the end of the study. The risperidone group showed a significant improvement in Y-BOCS obsession scores compared with aripiprazole. CONCLUSIONS: The present findings suggest that risperidone may be more effective than aripiprazole.

OBJECTIVE: We aimed to assess whether cognitive processes change over time in patients with obsessive-compulsive disorder (OCD) receiving selective serotonin reuptake inhibitors without cognitive behavioral therapy and to investigate the factors associated with probable cognitive changes. METHODS: During the 16 weeks of the study, 55 patients who met the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for OCD received open-label treatment with sertraline (100-200 mg/d) or fluoxetine (40-80 mg/d) and were assessed using the Yale-Brown Obsessive-Compulsive Scale, Beck Depression Inventory (BDI), Thought-Action Fusion Scale (TAFS), Metacognitions Questionnaire (MCQ-30), and White Bear Suppression Inventory (WBSI). RESULTS: The Yale-Brown Obsessive-Compulsive Scale (P < .001), BDI (P < .001), TAFS morality (P < .005), MCQ-30 (P < .01), and WBSI (P < .005) scores at follow-up were significantly lower than baseline scores. When we excluded OCD patients with depressive disorder (n = 12), statistical significance in paired comparisons for MCQ and WBSI disappeared. Similarly, when OCD patients with religious obsessions (n = 16) were excluded, paired comparisons for MCQ and TAF morality were not statistically significant. Changes in BDI, TAFS morality, MCQ-30, and WBSI (P < .005) were significantly correlated with changes in severity of obsessions, but not that of compulsions. After controlling for the change in depression severity, significant correlations between changes in obsessive and cognitive scales did not continue to have statistical significance. The BDI changes (P < .05) significantly explained the changes in symptom severity in a linear regression model. CONCLUSIONS: Our findings suggest that selective serotonin reuptake inhibitors can change appraisals of obsessive intrusions via their effects on negative emotions.

OBJECTIVE: The present study examined whether obsessive beliefs change over time in the OCD patients receiving selective serotonin reuptake inhibitors (SSRIs) and the impact of obsessive beliefs in treatment response. METHODS: In the first part of a two-stage study comparing the efficacy of antipsychotics as augmenting agent in SSRI-resistant OCD patients, 57 patients were interviewed with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Hamilton Depression Rating Scale (HDRS) and Obsessive Beliefs Questionnaire-44 (OBQ-44) before and after 12-week of SSRI treatment period. RESULTS: All OBQ-44 subscale scores significantly decreased with SSRI treatment. The mean changes in OBQ-44 Importance and Control of Intrusive Thoughts (I/CT) subscale and HDRS total scores of responders were significantly higher than those of SSRI-resistant patients. The baseline OBQ-44 P/C and Y-BOCS obsession subscale scores significantly predicted the treatment resistance in a logistic regression model. CONCLUSIONS: The alleviation of negative mood by SSRIs may help the sufferer to disengage from dysfunctional appraisals. Since individuals with highly obsessive beliefs about P/C are more likely to be resistant to SSRI treatment, the treatment of OCD can be made more effective when focusing on altering appraisals about P/C.

Due to the effects of sleep on the central nervous system, it is thought that sleep disorders have a special importance in the onset, course and treatment of psychiatric diseases. Although the negative effects of sleep problems on the occurrence, recurrence and clinical course of psychiatric disorders are well known, it is reported that clinicians do not spend enough time for sleep problems in practice. This may be related to the fact that patients underreport their complaints for various reasons, insufficient examination time, and clinicians' lack of knowledge about the importance of the subject. Pharmacotherapy, psychological and behavioral interventions are options among the therapeutic approaches to sleep problems. But, it seems that clinicians tend to prefer pharmacological approaches for the treatment of sleep problems. However, it is important to choose the appropriate treatment option with considering the method preferred by the patients, who already use many and high doses of pharmacological agents, the nature of the psychiatric disorder and the sleep problem. In this context, chronotherapeutic approaches such as bright light, sleep deprivation, interpersonal relations and social rhythm therapy, and cognitive behavioral therapy techniques adapted for patients with bipolar disorder can be used in the treatment of suitable patients. In this article, the current literature about sleep-related problems observed in patients with schizophrenia and bipolar disorder is reviewed comprehensively with presenting clinical phenotypes and treatment approaches.
RESUMO
A circadian rhythm is a 24-hour rhythm controlled by a master clock, the suprachiasmatic nucleus, and driven by synchronizing internal/external zeitgebers. Food intake is one of the most important external cues/zeitgebers. Studies in humans and animals have shown that misalignment of food intake leads to chronodisruption, which is associated with metabolic disruption, obesity, and disordered eating attitudes. The term chronotype, which expresses the circadian typology, has been classified into 3 main types that represent the differences in the reflection of circadian rhythms shown in human studies on daily behaviors. It has been reported that evening-type individuals are more prone to disrupted eating attitudes, such as skipping meals, eating at night, and consuming a calorie-rich diet. In addition, eating disorders up to the diagnostic level is associated with the evening type. The bidirectional relationship between impaired circadian rhythms and disordered eating attitudes has brought chronotherapeutic interventions, which are biological rhythm-oriented treatment approaches, to the agenda. Bright light therapy has been found to reduce bulimic eating behaviors and night eating symptoms. More evidence is needed regarding the effect of chronotherapeutic approaches on metabolic disorders, disordered eating attitudes, and eating disorders associated with obesity.
RESUMO
At least half of self-mutilative individuals report that seeing their own blood is comforting, while a quarter report that they have tasted it. Bloodletting and blood-drinking behaviors have been discussed in case reports of disorders such as borderline personality disorder, bulimia nervosa, dissociative identity disorder, and psychotic disorder. The role of blood-drinking behavior, however, needs to be clarified in the psychiatric literature. This paper is the first to discuss blood-drinking behavior as a possible impulse control disorder that progresses from a desire to see or taste one's own blood. It presents the cases of two patients who report drawing blood from their own arms via syringe and drinking it. The first patient began to suck her own blood by removing scabs at age 8. The second started cutting his arm during his middle school years to reduce tension. Both eventually began to drink their own blood by draining it impulsively. This paper presents two cases with blood-drinking behavior diagnosed as impulse control disorder not otherwise specified according to the Diagnostic and Statistical Manual of Mental Disorders. We propose the term "hemomania" to describe an impulse control disorder characterized by impaired functioning due to at least one of the following urges: seeing one's own blood, self-bloodletting, and tasting/drinking one's own blood. We argue that hemomania progresses from an urge to see one's own blood to the urge to drink it, though randomized controlled studies are needed to support this claim.

Treatment resistance, medication non-adherence, and side effects of pharmacotherapeutics make treatment difficult in major depressive disorder. Sleep deprivation is a fast-acting and tolerable reinforcement treatment method. In this study, we investigated the effects of late partial sleep deprivation (PSD) therapy added to venlafaxine treatment on symptoms of anxiety and depression, sleep quality and treatment process. This study was conducted in a sample of 40 patients who were admitted to our inpatient psychiatric unit with a diagnosis of major depressive disorder. While the venlafaxine (Ven) group received only venlafaxine treatment, the venlafaxine+partial sleep deprivation (Ven+PSD) group underwent late partial sleep deprivation therapy three times in the first week in addition to venlafaxine treatment. The Hamilton Anxiety Rating Scale (HAM-A), Hamilton Depression Rating Scale (HAM-D), Beck Depression Inventory, Pittsburgh Sleep Quality Index, and Insomnia Severity Index (ISI) were administered to both groups at the baseline and at the end of the 1st, 4th, and 6th weeks and, additionally, Profile of Mood State (POMS) was administered to the Ven+PSD group before and after each PSD. The Ven+PSD group had lower HAM-D and HAM-A scores than the Ven group at the end of the 1st and 6th week. Both anxiety and depression subscale scores on the POMS showed a significant decrease after PSD in the Ven+PSD group. The mean venlafaxine dose (mg/d) was significantly lower in the Ven+PSD group than in the Ven group. Late partial sleep deprivation is a fast-acting and tolerable therapy in major depressive disorder.
