Öğe Anxiety, depression and post-traumatic stress disorder symptoms in adolescents during the COVID-19 outbreak and associated factors(Wiley-Hindawi, 2021) Selcuk, Engin Burak; Demir, Arzu Caliskan; Erbay, Lale Gonenir; Ozcan, Ozlem Ozel; Gurer, Huseyin; Donmez, Yunus EmreIntroduction Outbreaks of infectious diseases have negative effects on mental health. Currently, there is very little information about the psychological effects of the COVID-19 pandemic on adolescents and associated factors affecting their mental health. The aim of the present study is to determine the severity of anxiety, depression and post-traumatic stress disorder (PTSD) symptoms in adolescents during the COVID-19 outbreak, and to investigate the associated factors with these symptoms. Methods The present study was conducted with a total of 447 adolescents. Psychiatric symptoms were evaluated by the use of DSM-5 Level 2 Anxiety Scale, DSM-5 Level 2 Depression Scale and National Stressful Events Survey PTSD Short Scale. The association between age, gender, residential area, presence of COVID-19 in the participant, presence of COVID-19 in the family or environment and psychiatric symptoms were evaluated with linear regression analysis. Results The mean age of participants was 15.06, and 38.3% of the participants were men and 61.7% were women. The rate of participants with moderate or high levels of anxiety, depression and PTSD symptoms was 28%, 37.6% and 28.5%, respectively. High age and living in an urban area were associated with increased anxiety, depression and PTSD symptoms. In addition, female gender was associated with increased depression symptoms, and the presence of COVID-19 in the family or environment was associated with increased anxiety symptoms. Conclusion The present study shows that adolescents have serious levels of anxiety, depression and PTSD symptoms during the COVID-19 pandemic. These results emphasise the need for mental health interventions that are appropriate for the characteristics of this age group.Öğe ASSOCIATION OF BDNF / TRKB AND NGF / TRKA LEVELS IN POSTMORTEM BRAIN WITH MAJOR DEPRESSION AND SUICIDE(Medicinska Naklada, 2021) Erbay, Lale Gonenir; Karlidag, Rifat; Oruc, Mficahit; Cigremis, Yilmaz; Celbis, OsmanBackgroundÖğe Brain Tumors and Atypical Psychiatric Symptoms: Two Case Presentations(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2018) Akan, Mustafa; Erbay, Lale Gonenir; Erbay, Mehmet Fatih; Unal, Suheyla[Abstract Not Available]Öğe Does Psychodrama Affect Perceived Stress, Anxiety-Depression Scores and Saliva Cortisol in Patients with Depression?(Korean Neuropsychiatric Assoc, 2018) Erbay, Lale Gonenir; Reyhani, Ismail; Unal, Suheyla; Ozcan, Cemal; Ozgocer, Tuba; Ucar, Cihat; Yildiz, SedatObjective Little is known about the effects of psychodrama group therapy on the level of stress, anxiety and depression of the group members, and the biological markers of stress. The aim of this study test cortisol level as a biological reflection of some mental characteristics gained by the psychodrama method in coping with stress. Methods Depressive patients aged between 18 and 65 years, who diagnosed with depression according to DSM-5, without psychiatric comorbidity, who do not use drugs and were available for psychodrama were enrolled into the study. These patients were evaluated using the Perceived Stress Scale, State-Trait Anxiety Inventory and Beck Depression Inventory. In order to observe the circadian rhythm of cortisol, samples were collected from the participants before lunch, before dinner and before going to sleep on the day before psychodrama and on the 0, 15th, and 30th minutes after awakening in the morning of the psychodrama day; as well as just before and after the psychodrama session. Saliva cortisol level just before the initial session of psychodrama group therapy was compared with the saliva cortisol level just after the last psychodrama session at the end of 16 weeks. Results Statistically significant difference was determined between the scores of perceived stress scale, STAI-1, STAI-2, beck depression inventory and salivary cortisol level before and after psychodrama session. There was significant decrease in both the scale scores and salivary cortisol after vs. before psychodrama. Conclusion This results is important as it shows the biological aspect of clinical improvement. Further studies would provide us with better understanding of the effects of psychodrama group psychotherapy on depressive mood and biological projections by means of short-term and long-term follow-up studies.Öğe Does psychodrama affect perceived stress, anxiety-depression scores and saliva cortisol in patientswith depression?(Korean neuropsychıatrıc assoc, rn 522, g-fıve central plaza 1685-8 seocho 4-dong, seocho-gu, seoul, 137-882, south korea, 2018) Erbay, Lale Gonenir; Reyhani, Ismail; Unal, Suheyla; Ozcan, Cemal; Ozgocer, Tuba; Ucar, Cihat; Yildiz, SedatObjective Little is known about the effects of psychodrama group therapy on the level of stress, anxiety and depression of the group members, and the biological markers of stress.

Method: A total of 72 morbidly obese women admitted to the Endocrinology Department, whose BMI scores were 40 or over, and 28 healthy women age-matched with the morbidly obese group, whose BMI scores were under 30 were included in this study. Considering the effects on sexual functioning, the patients and the control group were evaluated by a psychiatric specialist. women with a psychiatric disorder according to DSM-5, taking medicines that could affect sexual functions, and those with a chronic physical or any neurological disease or being pregnant or breastfeeding were excluded from the study. A sociodemographic data form and the Arizona Sexual Experiences Scale (ASEX) were administered to both the treatment and control group. Results: Statistical analyses revealed that morbidly obese female patients more frequently suffered from sexual dysfunction compared to the control group. The Arizona Sexual Experiences Scale (ASEX) and all subscale scores except the sexual satisfaction rate were significantly higher in morbidly obese female patients than in the control group. There was no correlation found between the BMI and sexual function in the analyses conducted. Conclusion: In our study, morbidly obese female patients were found to show more impairments in all areas of sexual functions except sexual satisfaction rate when compared to the control group. Previous studies have suggested that obesity is the cause of sexual dysfunction in men; however, the same relationship could not be demonstrated in women. In a limited study of female patients, conflicting results were attributed to the inability to control variables. The fact that variables such as depression, anxiety, and chronic physical illness, which may affect sexual function, had been assessed in our study is important for accurately interpreting the findings. The data in our study reveals the importance of investigating sexual functions in morbidly obese female patients.Öğe Effects of Electroconvulsive Therapy on Some Inflammatory Factors in Patients With Treatment-Resistant Schizophrenia(Lippincott Williams & Wilkins, 2016) Kartalci, Sukru; Karabulut, Aysun Bay; Erbay, Lale Gonenir; Acar, CerenObjectives Electroconvulsive therapy (ECT) is the most effective option for several psychiatric conditions, including treatment-resistant schizophrenia. However, little is known about the molecular mechanism of action of ECT. The link between inflammatory system and schizophrenia is the focus of recent studies. However, the impact of ECT on inflammatory functioning in this disorder remains elusive. Whether ECT could modulate inflammatory factors in patients with schizophrenia was examined. Methods Plasma levels of interleukin-4 (IL-4), transforming growth factor- (TGF-), myeloperoxidase (MPO), and nuclear factor-B (NF-B) activation were analyzed in 20 schizophrenic patients, mainly with resistant to antipsychotic medication disorders, and in 20 sex- and age-matched healthy controls. Disease severity was evaluated using the Brief Psychiatric Rating Scale. All patients were followed with measurement of the inflammatory factors before and after ECT treatment and compared with the controls. Results Patients with schizophrenia had markedly raised NF-B and but decreased TGF- levels compared with healthy controls. On the other hand, no significant differences were found for the levels of IL-4 and MPO levels. The clinical improvement during repeated ECT was accompanied by a gradual and significant increase in IL-4 and TGF- level, but MPO and NF-B activation were left unaffected. Increases in TGF- were negatively correlated with the change in Brief Psychiatric Rating Scale scores after ECT. Conclusions It is shown that ECT, while increasing the anti-inflammatory response such as the levels of IL-4 and TGF-, it did not affect the levels of MPO and NF-B activation in this study.Öğe Evaluation of CSF flow dynamics in patients with schizophrenia using phase-contrast cine MRI(Elsevier Ireland Ltd, 2021) Kartalci, Sukru; Erbay, Mehmet Fatih; Kahraman, Aysegul; candir, Fatih; Erbay, Lale GonenirPatients with schizophrenia show progressive clinical deterioration. Brain abnormalities have been suggested in these patients, including enlargement of the lateral ventricles, increased cerebrospinal fluid (CSF) volume and reductions in the frontal and temporal lobes. CSF flow pathology is a central factor in the development of many neurological disorders, but much less is known about the role of CSF flow dynamics in schizophrenia. In this study, parameters of CSF flow dynamics at the aqueduct level of 50 schizophrenic patients were compared to those of 50 controls using phase-contrast cine magnetic resonance imaging. Patients had lower peak velocity, lower net forward volume, and lower average flow over the range studied than controls. The average velocity was significantly lower in patients exhibiting violent behavior compared to non-violent patients. The aqueduct tendedto be larger in schizophrenic patients with earlier age of onset of the disorder. Furthermore, as the number of hospitalizations increased, the average velocity and flow over the range studied decreased commensurately. This study demonstrated that CSF flow dynamics are altered in patients with schizophrenia. The results indicated that additional studies of CSF flow dynamics in schizophrenia are needed, along with volumetric examinations of the brain, to elucidate the pathophysiology of the disease.Öğe Evaluation of Transcranial Magnetic Stimulation Efficiency in Major Depressive Disorder Patients: A Magnetic Resonance Spectroscopy Study(Korean Neuropsychiatric Assoc, 2019) Erbay, Mehmet Fatih; Zayman, Esra Porgali; Erbay, Lale Gonenir; Unal, SuheylaObjective Repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for major depressive disorder (MDD). This study evaluated the antidepressant effect of rTMS and examined how it affected N-asetyl aspartate (NAA), choline (Cho), creatine (Cr), lactate (Lac), inyoinositol (mins), glutamate (Glu), glutathione (GSH), and glutamine (Gln) metabolite levels in the left dorsolateral prefrontal cortex (DLPFC) of MDD patients who were not receiving antidepressant medication. Methods In total, 18 patients (10 female, 8 male) were evaluated. Each patient underwent H magnetic resonance spectroscopy (H-MRS) before and within 3 days of completion of TMS therapy. All patients completed 20 sessions of rTMS directed at the left DLPFC over a 2-week period. The Hamilton Depression Scale (HAMD) scores of patients were calculated, and their responses to treatment were assessed within 1-3 days of completion of TMS. Results We found statistically significant differences in HAMD scores before and after rTMS. Moreover, the peak metabolite ratios of NAA/Cr, GSH/Cr, and Gln/Cr were significantly higher after rTMS compared to those before rTMS. Conclusion Increased understanding of the mechanism of action of TMS will improve its application and may stimulate development of new generation therapeutic agents.Öğe IL-4, TGF-?, NF-?B and MPO levels in Patients with Treatment Resistant Schizophrenia(Turkiye Sinir Ve Ruh Sagligi Dernegi, 2016) Kartalci, Sukru; Erbay, Lale Gonenir; Zayman, Esra Porgali; Otlu, Onder; Karabulut, Aysun Bay; Kartalci, GulsenObjective: Schizophrenia is a chronic psychotic disorder in which genetics and environmental factors such as infection and the corresponding immune response play a role in the etiopathogenesis. The aim of this study was to compare some immune factors such as nuclear factor-kappa B (NF-kappa B) activation, myeloperoxidase (MPO), the anti-inflammatory cytokine interleukin-4 (IL-4), and regulatory cytokine transforming growth factor-beta (TGF-beta) in schizophrenia patients and an age- and gender-matched control group. Method: Plasma levels of IL-4, TGF-beta, MPO, and NF-kappa B activation in 20 subjects with treatment-resistant schizophrenia and 20 age- and gender-matched healthy controls were analyzed. Disease severity was evaluated using the Brief Psychiatric Rating Scale (BPRS). Results: Plasma TGF-beta levels were found to be significantly lower and NF-kappa B to be significantly higher in antipsychotic treatment-resistant schizophrenia patients than in controls in this study. No significant differences were found between the patient and control groups for serum IL-4 and MPO levels. Conclusion: The low TGF-beta level in treatment-resistant schizophrenia patients in the symptom exacerbation period indicates that there is inadequate Th1/Th2 balance. Large-scale studies are required to investigate whether this is responsible for resistance in schizophrenia. The fact that the increase in NF-kappa B that we found in treatment resistant schizophrenia patients in this study has also been reported in the first attack in untreated schizophrenia patients in previous studies indicates that NF-kappa B plays a role in the disorder's physiopathology from the beginning.Öğe Is There Any Relation Between Pseudoexfoliation Syndrome and Alzheimer's Type Dementia?(Taylor & Francis Inc, 2013) Cumurcu, Tongabay; Dorak, Ferhat; Cumurcu, Birgul Elbozan; Erbay, Lale Gonenir; Ozsoy, ErcanPurpose: To investigate the frequency of Alzheimer-related dementia in patients with pseudoexfoliation syndrome (PEX). Methods: Sixty-seven patients with PEX and 67 age-, gender-, and educational-background-matched control subjects were compared for the presence of Alzheimer-related dementia according to DSM-IV-TR. The effects of cataract, glaucoma, additional ocular and systemic disease on the dementia incidence were also evaluated in patients with PEX and the control group. Results: The frequency of Alzheimer-related dementia was higher in patients with PEX (p = 0.0001). The frequency of dementia in patients who had cataract was higher than in patients without cataract (p = 0.003). There was also an association between additional ocular disease and dementia (p < 0.05). However, there was no association between systemic disease and dementia (p > 0.05). Furthermore, there was no difference for the frequency of dementia between patients who had glaucoma or not among patients with PEX (p = 0.953). Conclusion: The increased frequency of Alzheimer-related dementia in patients with PEX is important and a possible association between PEX and Alzheimer's disease could be present.Öğe Neurosteroid Levels in Patients with Obsessive-Compulsive Disorder(Korean Neuropsychiatric Assoc, 2015) Erbay, Lale Gonenir; Kartalci, SukruObjective Changes in serum neurosteroid levels have been reported in stress-related disorders such as anxiety and depression, but not in patients with obsessive-compulsive disorder (OCD). We thus investigated such changes in patients with OCD. Methods We compared the serum levels of progesterone, pregnanolone, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulphate (DHEA-S), cortisol and testosterone in 30 patients with OCD and 30 healthy controls. Results When male and female patients were evaluated together, DHEA and cortisol levels were significantly higher in patients with OCD than the control group. When the genders were evaluated separately, DHEA and cortisol levels were higher in female patients than the female controls. The increase in DHEA levels in female patients is likely an effect of the hypothalamic-pituitary-adrenal (HPA) axis. In contrast, cortisol levels in male patients were higher than the control group, while testosterone levels were lower. The increased cortisol and decreased testosterone levels in male patients likely involves the hypothalamic-pituitary-gonadal (HPG) axis. Conclusion These findings suggest that neurosteroid levels in patients with OCD should be investigated together with the HPA and HPG axes in future studies.Öğe No evidence of androgenic neurosteroid involvement in pediatric OCD(Elsevier Science Bv, 2015) Erbay, Lale Gonenir; Ozcan, Ozlem Ozel; Kartalci, Sukru; Yuksel, Tugba; Kutuk, Meryem OzlemCertain androgenic neurosteroids have been shown to have a relationship with anxiety disorders in adults. Demonstrating these changes in pediatric patients as well is important in terms of elucidating the etiology of these disorders. The aim of this study was to investigate the testosterone, DHEA-S and cortisol levels in pediatric obsessive-compulsive disorder (OCD) patients. A total of 39 pediatric OCD patients aged 7-16 years and 34 healthy children of similar age and gender were included in this study. Serum total testosterone, DHEA-S and cortisol levels were measured by using the ELISA method and their relationship with clinical data was investigated. No statistically significant difference was found between the patient and control groups in terms of testosterone, DHEA-A and cortisol levels in the analyses performed (p=0.175, p=0.642. p=0.842. respectively). The results of this first study have revealed that testosterone, DHEA-S and cortisol levels in pediatric OCD patients are not different than in the controls. However, the fact that these neurosteroid levels have been found to differ between adult patients and controls previously indicates that neurosteroid changes may be a finding that appears during the course of anxiety disorders.

Nevertheless, allopregnanolone, a neurosteroid, in OCD patients has not been investigated in this limited number of studies. Allopregnanolone is considered to have a role in the pathogenesis of many psychiatric disorders. Accordingly, the present study aimed to investigate the relationship between the neurosteroid allopregnanolone and OCD. Methods: The study included 40 OCD patients diagnosed based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) diagnostic criteria and 40 healthy control subjects. The study participants completed the Yale-Brown Obsessive Compulsive Scale. Taking the diurnal rhythm of neurosteroids into consideration, blood samples for determination of plasma allopregnanolone levels were obtained from all patients and controls between 09: 00 and 10: 00 in the morning after 12 hours of fasting, tobacco abstinence, and 30 minutes of resting period. Plasma allopregnanolone level was analyzed using the enzyme-linked immunosorbent assay (ELISA). Results: No significant difference was determined between the patient and control groups regarding serum allopregnanolone levels. Evaluation of the allopregnanolone levels of the patients for each obsession type according to its presence and absence revealed no significant difference in any of them. Evaluation of the allopregnanolone levels of the patients for each compulsion type according to its presence and absence revealed that the allopregnanolone level of the patients with counting-organizing compulsive behavior was lower than that of those without. Discussion: Although there was no difference between OCD patients and controls regarding plasma allopregnanolone level, it is difficult to make a conclusion that allopregnanolone level does not play a role in the etiopathogenesis of disease. Conducting further studies, which would analyze allopregnanolone level in materials other than plasma such as cerebrospinal fluid using multiple analyses and separately evaluates females and males with higher number of patients, is of importance to enlighten at least some aspects of allopregnanolone-OCD relationship. Moreover, significantly lower plasma allopregnanolone level particularly in a single type of compulsion brings in mind again the suggestion that different etiopathogenesis might have a role in the symptom subtypes of OCD, which has begun to be discussed in the recent years.Öğe Plasma allopregnanolone levels in drug-free, comorbidity-free obsessive-compulsive disorder(Cumhurıyet unıv tıp fak psıkıyatrı anabılım dalı, cumhurıyet unıv tıp fak psıkıyatrı abd, sıvas, 58140, turkey, 2018) Ince, Lara Utku; Erbay, Lale GonenirObjective: Although there are studies in the literature focusing on the relationship between neurosteroids and psychiatric disorders, the studies on patients with obsessive-compulsive disorder (OCD) are limited in number.

Sixty-seven patients who were diagnosed with OCD were included in the study out of the patients who were admitted to Malatya Training and Research Hospital psychiatry outpatient clinic. The research data were collected using Yale Brawn Obsessive Compulsive Scale (YBOCS), Beck Depression (BDS) and Beck Anxiety Scales (BAS), Childhood Trauma Questionnaire-28 (CTQ-28), and Suicide Probability Scale (SPS). CTQ was detected as 35 in 36 of 67 patients who were included in the study. Aggression (p = 0.003), sexual (p = 0.007) and religious (p = 0.023) obsessions and rituelistic (p = 0.000) compulsions were significantly higher in the group with CTQ >= 35. Mild correlation was detected between the SPS score and the scores of CTQ. Correlation remained even when the effect of BAS and BDS scores were excluded. At the end of our study, childhood traumas were found to be associated with obsessive symptoms. In the group with childhood trauma, increased suicide probability was detected independently from depression and anxiety.Öğe Serum IL-1, IL-2, IL-4, IL-6, IL-10, TNF-?, and IFN-? levels in drug-free, comorbidity-free obsessive-compulsive disorder patients(Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2018) Erbay, Lale Gonenir; Akti Kavuran, Nursel; Taskapan, Cagatay; Ince, Lara Utku; Yologlu, Saim; Temelli, Husniye Gul; Unal, SuheylaObjective: Increasing evidence suggests that certain inflammatory factors, especially cytokines, can lead to neurochemical and behavioural changes via their role in the brain signalling system. Studies investigating cytokine abnormalities in obsessive-compulsive disorder (OCD) have yielded conflicting results thus far. The aim of this study was to investigate the serum IL-1, IL-4, IL-6, IL-10, TNF-alpha, and IFN-gamma levels in drug-free, comorbidity-free patients with OCD. Methods: Forty comorbidity-free, drug-free OCD patients and 40 age-and sex-matched healthy volunteers were included in the study. Clinical severity was assessed using the Yale-Brown Obsessive-Compulsive Evaluation Scale (YBOCES). Results: IL-1 levels were significantly higher and IL-2, IL-6, and TNF-alpha levels were significantly lower in patients than in controls. No differences were observed in IL-4, IL-10, and IFN-gamma levels. However, a negative relationship was found between IL-1 levels and compulsive symptoms (YBOCES) in OCD patients. Conclusions: Our findings suggest the possible role of cytokines in the pathogenesis of OCD. It is important to continue investigating the role of cytokines and other immunological markers in both the etiology and treatment of OCD.Öğe Stuttering after testosterone administration: A case report(Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2012) Kartalci, Sukru; Erbay, Lale Gonenir; Ozcan, Ozlem Ozel; Yuksel, Tugba; Unal, SuheylaStuttering is defined as a disturbance in the normal fluency and time patterning of speech. There are two kinds of stuttering: developmental and acquired. However, the etiology of stuttering is controversial; it is well known that the sex of the patient clearly influences stuttering. There is a higher incidence of stuttering in males than in females. Furthermore, although stuttering is common in children, it often resolves before adulthood in especially females. Environmental influences, such as stressful social situations which are associated with elevated androgen secretion, may also contribute to the persistence of stuttering. Considering all this together, one of the reasons underlying this gender difference in stuttering may be sex hormones. Acquired stuttering can occur at all ages and can be caused by pharmacological agents. Testosterone is an androgenic drug that has diverse side-effects, but an extensive review of the literature has failed to show stuttering as one of the complications. We present a case in which testosterone was implicated as a potential cause of stuttering. (Anatolian Journal of Psychiatry 2012;13:82-84)Öğe Testosterone and DHEA-S levels with chronic tic disorder in children(Elsevier Science Bv, 2016) Erbay, Lale Gonenir; Kartalci, Sukru; Ozcan, Ozlem Ozel; Demir, Arzu Caliskan; Uyumlu, Ayse Burcin; Kutuk, Meryem OzlemThe neurobiological basis of tic disorders is thought to be a series of interactions including genetic, environmental and gender related factors. Being male is thought to be an especially important risk factor in the pathogenesis of tics. Our aim in this study was to investigate gender-related hormones such as testosterone, dehydroepiandrosterone sulfate (DHEA-S) and cortisol in tic patients. A total of 26 patients who had not entered puberty and had been diagnosed with chronic tic disorder and 25 healthy children were included in the study, Serum total testosterone, cortisol and DHEA-S levels were measured and the relationship with clinical data was investigated. The testosterone and DHEA-S levels of the patient group were higher than that of the control group (P=0.019, P=0.025) but no statistical difference was found between the cortisol levels (P=0.642). No statistical correlation was found between total tic severity, general disturbance, movement tic subscale scores and the DHEA-S (P=0.77, P=0.45, P=0.819 respectively) and testosterone levels (P=0.954, P=0.669, P=0.909 respectively). The results of this study reveal an elevation of testosterone and DHEA-S levels in patients. Future studies with a larger number of patients are likely to help elucidate the importance of these androgens in tic disorder. (C) 2016 Elsevier Inc.

The effect of sex on development and chronicity of stuttering is well known; it is more common and chronic in males. We aimed to investigate the relationship between developmental stuttering and serum testosterone levels in this study. Materials and methods: In this study, we evaluated a total of 50 children (7-12 years of age); eight (16%) were female and 42 (84%) were male. Twenty-five children who stutter and 25 typically fluent peers with the same demographic properties (ages between 7 years and 12 years) were included in this study. The testosterone levels of the two groups were determined in terms of nanogram per milliliter (ng/mL) by enzyme-linked immunosorbent assay. The difference between the means of the two groups was analyzed. Results: The medians of the testosterone levels of the stutterer and control groups were determined as 20 ng/mL (range =12-184 ng/mL) and 5 ng/mL (range =2-30 ng/mL), respectively. Testosterone levels of the stutterer group were significantly higher than in the control group (P=0.001). Besides, there was a significant correlation between the severity of the stuttering and testosterone levels in the stutterer group (P=0.0001). Conclusion: The findings of this study show that testosterone may have an effect on the severity of developmental stuttering and on the clinical differences between sexes. However, further investigations are needed to show that testosterone may play a role in the etiology of developmental stuttering.
