ADHD and Anxiety Disorder Comorbidity in Children and Adults: Diagnostic and Therapeutic Challenges.

PURPOSE OF THE REVIEW: In this review, we focus on overlapping features of ADHD and anxiety disorders, and will discuss how an anxiety disorder comorbidity leads to diagnostic and treatment challenges in patients with ADHD, in consideration of the accumulated available knowledge. RECENT FINDINGS: The presence of overlapping symptoms, changes in the diagnostic criteria, and the use of divergent diagnostic tools and informant effects can complicate the diagnosis of this comorbidity. Due to the ongoing debate about the etiology, psychopathology, and diagnostic features of the association between ADHD and anxiety disorders, choosing appropriate treatment options emerges as a challenge. A novel methodology, standardized interview tools, and new statistical analysis methods are needed to define the phenotype of this co-occurrence more clearly. It is important to uncover the developmental nature of this comorbidity with follow-up studies that may explain the etiology and underlying neurobiological basis, and ultimately lead to more effective treatment approaches.

Is malignancy associated with pericardial effusion fluid volume or fluid character?

INTRODUCTION: Pericardial effusion develops due to different etiologies. The main goals of our study are to understand the etiology and determine whether the amount of pericardial effusion is significant in terms of malignancy. MATERIAL AND METHODS: 142 patients with pericardial effusion, who met the criteria between 1 January 2014 and 1 January 2019, were retrospectively analyzed. All of these patients underwent operation with the subxiphoidal approach. The fluid samples were sent to the microbiology and pathology laboratories for evaluation. Patients underwent follow-up after 1 month. RESULTS: Of the patients included in this study, 72 (61%) of 118 patients were operated on under general anesthesia with a laryngeal mask, and 46 (39%) underwent sedation and local anesthesia. The etiologies found in patients were as follows: effusions resulting from malignancy in 27 (22.9%), idiopathic in 24 (20.3%), cardiac causes (depending on the use of anticoagulants or postoperation) in 22 (18.6%), uremia in 20 (16.9%), infection in 18 (15.3%), and heart failure in 7 patients. The amount of fluid drained from the patients was 661.61 ± 458.34 mL. Out of 27 patients with malignancy, 21 (77.8%) had drainage over 500 mL of effusion fluid, and 6 (22.2%) had drainage under 500 mL. Patients who had positive results tended to have drainage over 500 mL compared with patients who had negative results in terms of malignancy (P = .033). CONCLUSION: The subxiphoidal approach to pericardial effusion is an easily applicable operation, whether therapeutic or diagnostic. The advantages of the subxiphoidal approach include drainage of all of the fluid and ease of sampling the pericardial fluid. We believe that the amount of fluid drained can lead us to consider malignancy as an etiology.

Comparison of Short and Mid-Term Mortality and Morbidity in Patients With Severe Aortic Stenosis (Intermediate/High Risk) Who Underwent Transcatheter Aortic Valve Replacement and Surgical Aortic Valve Replacement.

Treatment protocols for severe aortic valve stenosis include surgical aortic valve replacement (SAVR), balloon valvuloplasty, transcatheter aortic valve replacement (TAVR), and medical  treatment. Because the success rates are getting higher with both SAVR and TAVR, making the right treatment decision is important. This study retrospectively shows the short- (1 month) and mid-term (6 months) mortality and morbidity rate differences between 2 groups of patients, who arrived to our hospital from January 2014 through October 2018. The first group consists of 54 patients who underwent mid-high risk SAVR operations at Istanbul University-Cerrahpasa, Institute of Cardiology, Department of Cardiovascular Surgery. The second group consists of 57 patients who underwent TAVR at the Cardiology Department. Preoperative evaluation showed that the mean age of the SAVR group (71.5 years) was higher than the TAVR group (80 years). Also, the history of previous cardiac valve replacement surgery significantly was higher in the SAVR group than the TAVR group (P = .028). There were no significant differences between the remaining preoperative tests and diagnostic procedures. Of the patients who underwent SAVR, 3.7% experienced postoperative cardiac arrhythmias, while the 17.5% of patients from the TAVR group experienced cardiac arrhythmias after the procedure. This difference between the groups were statistically significant. Mortality rate was 9.3% in the SAVR group and 5.3% in the TAVR group. The mortality rate was not statistically different between the groups. There was no significant difference between the groups in the means of neurological incidents. The TAVR group had more vascular complications (17.9% to none) and pacemaker implantations (21.4% to 1.9%). Minor or major bleeding was the most common reason for admission to the hospital after SAVR. Seven out of 10 patients experienced bleeding. Aortic regurgitation was more common in the TAVR group at the first and sixth month following the procedure. Ratios between the gradient values were higher in the SAVR group (P < .001). Peak gradient values at the sixth month following the procedure were lower than the values of the first month (P < .040). Aortic regurgitation symptoms increased with patients at the mid-term follow-up appointment. To prevent the vascular complications in the TAVR group, preoperative peripheral vascular examination thoroughly should be performed. Considering that bleeding disorders are the main reason the SAVR group arrived to the hospital, INR values should closely be monitored. There seems to be no mortality difference between the groups at the six-month follow up, but studies should continue with more patients and long-term results.

Proton Magnetic Resonance Spectroscopy in Social Anxiety Disorder.

In the present study, 24 nonmedicated patients with social anxiety disorder (SAD) were compared with 24 healthy control subjects to assess metabolite levels in the anterior cingulate, insula, caudate, and putamen using proton magnetic resonance spectroscopy. The ratio of N-acetylaspartate (NAA)/creatine (Cr) was significantly higher in patients with SAD than in healthy control subjects in the anterior cingulate and insula. NAA/Cr ratios in the insula correlated positively with the Liebowitz Social Anxiety Scale total scores in patients with SAD. Our results support the significance and biochemical involvement of the anterior cingulate and insula in the pathophysiology of SAD.

Predictors of early or late treatment seeking in patients with social anxiety disorder.

BACKGROUND: Social anxiety disorder (SAD) is common in the general population and usually begins at an early age. It is well established that patients with SAD rarely seek treatment, and their first treatment contact usually takes many years after onset. The aim of this study was to determine the predictors of early and late treatment seeking in patients with SAD. METHODS: This study enrolled 180 patients with generalized SAD. The mean and median durations between the emergence of SAD and first treatment contact were 15 and 14 years, respectively. Multiple linear regression with the backward elimination method was applied to assess the factors that affect the amount of time between occurrence of the disorder and first treatment contact. RESULTS: Older age, earlier onset of SAD, and lower level of education were associated with late treatment seeking, whereas earlier onset of comorbid major depressive episodes and lifetime history of comorbid obsessive-compulsive disorder were associated with earlier treatment seeking. CONCLUSIONS: Age of onset, comorbid psychiatric conditions, and level of education are associated with the timing of treatment seeking in patients with SAD. It is important to try to change the common perception that SAD is a personality trait rather than a psychiatric disorder.

Age of onset in social anxiety disorder: Relation to clinical variables and major depression comorbidity.

BACKGROUND: The aim of this study was to determine the rates of early- and late-onset social anxiety disorder (SAD) and to investigate the effects of onset time on clinical characteristics and the course of SAD. METHODS: A total of 377 patients with SAD were assessed using a sociodemographic data form, the Liebowitz Social Anxiety Scale (LSAS), Beck Depression Inventory (BDI), and the Global Assessment of Functioning (GAF). Three hundred patients with SAD onset before age 18 were classified as members of the early-onset group, whereas 77 patients with SAD onset at age ≥ 18 comprised the late-onset group. The 2 groups were compared in terms of sociodemographic and clinical characteristics, comorbidity, and scale scores. RESULTS: The rate of SAD onset before age 18 was 79.6%. Compared with the late-onset group, the early-onset group had a younger age at first depressive episode, higher rate of atypical depression, higher LSAS and BDI scores, and lower GAF scores. CONCLUSIONS: In cases of early onset of SAD, symptom severity of both SAD and comorbid depression increased and functionality decreased. It is important to assess and treat SAD patients at a younger age because early-onset SAD may be associated with a more severe course and higher rate of major depression comorbidity.

The clinical impact of mood disorder comorbidity on social anxiety disorder.

BACKGROUND: High comorbidity rates of mood disorders have been reported in patients with social anxiety disorder (SAD). Our study aims to identify the frequency of comorbid Axis I disorders in patients with SAD and to investigate the impact of psychiatric comorbidity on SAD. METHODS: The study included 247 patients with SAD. Thirty eight patients with bipolar depression (SAD-BD), 150 patients with major depressive disorder (SAD-MDD) and 25 patients who do not have any mood disorder comorbidity (SAD-NOMD) were compared. RESULTS: Around 90% of SAD patients had at least one comorbid disorder. Comorbidity rates of lifetime MDD and BD were 74.5% and 15.4%, respectively. There was no comorbidity in the SAD-NOMD group. Atypical depression, total number of depressive episodes and rate of PTSD comorbidity were higher in SAD-BD than in SAD-MDD. Additionally, OCD comorbidity was higher in SAD-BD than in SAD-NOMD. SAD-MDD group had higher social anxiety severity than SAD-NOMD. CONCLUSIONS: Mood disorder comorbidity might be associated with increased severity and decreased functionality in patients with SAD.

Endovascular treatments of atherosclerotic renovascular disease: a narrative review and literature search.

In recent years, endovascular treatments have become more common in patients with renal artery stenosis and aneurysm. Although the treatment algorithms are not universally accepted, endovascular therapy can be readily utilized for the appropriate indications in the context of surgical treatment for renovascular diseases. The most important factor to consider is that the correct indication is applied for such treatment. Although the applied procedures are believed to have minimal risk, any complications that occur may result in major problems. Moreover, the pathology that is being treated (e.g., hypertension, high serum creatinine concentration, or low glomerular filtration rate) must be well defined. As stent and balloon technologies continue to be developed, more positive results are expected in the coming years. In the present study, we reviewed the endovascular treatment algorithms for atherosclerotic renovascular disease and performed a narrative review of the current literature.

Impact of obsessive-compulsive disorder comorbidity on the sociodemographic and clinical features of patients with bipolar disorder.

BACKGROUND: In this study, our aim is to determine the prevalence rates of obsessive-compulsive disorder (OCD) comorbidity and to assess the impact of OCD comorbidity on the sociodemographic and clinical features of patients with bipolar disorder (BD). METHODS: Using the Yale-Brown Obsessive Compulsive Scale Symptom Checklist and Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-IV/Clinical Version on bipolar patients, 2 groups, BD with OCD comorbidity (BD-OCD) and BD without OCD comorbidity, were formed. These groups were compared for sociodemographic and clinical variables. RESULTS: Of 214 patients with BD, 21.9% of them had obsession and/or compulsion symptoms and 16.3% had symptoms at the OCD level. Although there was no statistically significant difference between the frequency of comorbid OCD in BD-I (22/185, 11.9%) and BD-II (3/13, 23.1%) patients, but OCD was found to be significantly high in BD not otherwise specified (10/16, %62.5) patients than BD-I (P < .001) and BD-II (P = .03). Six patients (17.1%) of the BD-OCD group had chronic course (the presence of at least 1 mood disorder episode with a duration of longer than 2 years), whereas the BD without OCD group had none, which was statistically significant. There were no statistically significant differences between BD-OCD and BD without OCD groups in terms of age, sex, education, marital status, polarity, age of BD onset, presence of psychotic symptoms, presence of rapid cycling, history of suicide attempts, first episode type, and predominant episode type. LIMITATIONS: Main limitation of our study was the assessment of some variables based on retrospective recall. CONCLUSIONS: Our study confirms the high comorbidity rates for OCD in BD patients. Future studies that examine the relationship between OCD and BD using a longitudinal design may be helpful in improving our understanding of the mechanism of this association.

The Features of Comorbidity of Childhood ADHD in Patients With Obsessive Compulsive Disorder.

Objective: Our aim is to investigate the impact of childhood ADHD comorbidity on the clinical features of obsessive compulsive disorder (OCD). Method: Ninety-five adult outpatients with a diagnosis of OCD were assessed by using the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version, ADHD module, and the Yale-Brown Obsessive Compulsive Scale. Patients with or without childhood ADHD were compared in terms of the sociodemographic and clinical features, psychiatric comorbidities, and rating scales. Results: The rate of episodic course of OCD (p < .001), religious and sexual obsessions (p = .009, p = .020, respectively), lifetime comorbidity of bipolar disorder (BD), social anxiety disorder (SAD; p = .001, p = .009, respectively), and tic disorder (TD) comorbidity (p < .001) were higher in the OCD + ADHD group than in the OCD without ADHD group. Conclusion: Childhood ADHD may be associated with higher rates of BD, SAD, and TD comorbidity and episodic course of OCD as well as higher frequency of certain types of obsessions.

Is it possible to predict atherosclerosis in the ascending aorta by the patient's lipid panel?

INTRODUCTION: Atherosclerosis is a chronic inflammatory event characterized by stiffness and thickening of the vascular walls. In our daily practice, we assume the atherosclerotic potential of the patient by following the total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triglyceride levels (lipid panel). We aimed to understand the relation between the HDL, LDL, cholesterol levels and the atherosclerosis in large vascular structures such as the ascending aorta. MATERIAL AND METHODS: We have searched for atherosclerosis in the aortic tissue samples from 48 patients. It is a study in which we examine the correlation of preoperative cholesterol values (HDL, LDL, triglyceride, total cholesterol) by dividing the patients into two groups according to the presence of plaque. RESULTS: Forty-three (89.6%) male and 5 (10.4%) female patients between 39 and 81 years of age were included in the study. There was no statistically significant difference between the patients' preoperative cardiovascular risk assessments. The free T3 values were within the normal range in all patients, but there was a difference that patients in the non-atherosclerosis group had lower values. There was no statistically significant difference between the two groups' HDL, LDL, total cholesterol, or triglyceride parameters. CONCLUSIONS: As a result, in our study, no significant difference was found between HDL-C, LDL-C, triglyceride, total cholesterol values and the pathological process of aortic atherosclerosis. As a result of this study, we believe that it was necessary to correct the error margins of these parameters. In addition, it required the need for a clearer laboratory parameter to demonstrate atherosclerosis.

Is there a prodrom period in patients with social anxiety disorder? A discussion on the hypothesis of social anxiety disorder development secondary to attention-deficit/hyperactivity disorder.

The association between social anxiety disorder (SAD) and attention-deficit/hyperactivity disorder (ADHD) is poorly established. In fact, increasing and converging evidences suggest that there is a close relationship between the two disorders. High comorbidity rate between these two disorders, follow-up studies showing high rates of later development of SAD in ADHD and treatment studies in which ADHD medications have been helpful for both conditions all indicate this relationship. Recently, we have published a hypothesis regarding the development of SAD secondary to ADHD. In this hypothesis, we recognized that patients with SAD seem to go through a prodromal period that we labeled as "pre-social anxiety." Detecting patients in this period before meeting full-blown SAD criteria provides early intervention and prevention of SAD. New, comprehensive follow-up studies which will investigate whether ADHD causes later SAD secondarily are needed. In the current review, taken into account our developmental hypothesis, we will discuss whether high comorbidity of SAD and ADHD is a chance finding (i.e., the two disorders are found in cases with no causal relationship between them) or can SAD develop secondarily due to childhood ADHD. Is there a prodrom period in patients with SAD as in cancer or psychosis patients? We are going to summarize the overlapping features of SAD and ADHD in terms of child/parents interaction and family issues, aversive childhood experiences, social skill deficits, and development of cognitive distortions.

Comorbidity in social anxiety disorder: diagnostic and therapeutic challenges.

Comorbid disorders are highly prevalent in patients with social anxiety disorder, occurring in as many as 90% of patients. The presence of comorbidity may affect the course of the disease in several ways such as comorbidity in patients with social anxiety disorder (SAD) is related to earlier treatment-seeking behavior, increased symptom severity, treatment resistance and decreased functioning. Moreover, comorbidities cause significant difficulties in nosology and diagnosis, and may cause treatment challenges. In this review, major psychiatric comorbidities that can be encountered over the course of SAD as well as comorbidity associated diagnostic and therapeutic challenges will be discussed.

Clinical Effects of ADHD Subtypes in Patients With Social Anxiety Disorder.

Objective: Our aim in this study is to evaluate the impacts of inattentive and combined types of childhood ADHD (ADHD-I, ADHD-C) in patients with social anxiety disorder (SAD). Methods: A total of 142 adult outpatients with a primary diagnosis of SAD were included. All patients were assessed by using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), ADHD module and a clinical and sociodemographic data form and scales were filled out. Results: Childhood ADHD comorbidity rates was found to be 88 (62%) in patients with SAD, and 63 of these patients had the diagnosis of ADHD-I. ADHD-I group had higher scores of social anxiety and avoidance and had earlier onset of SAD than the ADHD-C group. Conclusion: The inattentive subtype of ADHD may have a more specific relationship with SAD than ADHD-C.

Intrinsic functional connectivity in social anxiety disorder with and without comorbid attention deficit hyperactivity disorder.

Neuroimaging research about social anxiety disorder (SAD) points to hyperactivity in the fear circuit and altered connectivity between the fear circuit and the intrinsic connectivity networks that modulate it. We investigated intrinsic functional connectivity changes in SAD patients by taking into consideration the commonly overlooked comorbidity of attention deficit hyperactivity disorder (ADHD). We compared intrinsic functional connectivity alterations in 16 patients with pure SAD, 18 patients with SAD and comorbid ADHD and 21 healthy controls using seed-to-voxel functional connectivity analyses. Hypoconnectivity of the right fusiform gyrus with the left lingual gyrus was the unique difference between whole SAD group and healthy controls, while in the pure SAD group the fusiform gyrus displayed hypoconnectivity with the posterior default mode network (DMN) regions. In contrast, ADHD comorbidity was associated with hyperconnectivities of the salience network (SN) with the fusiform cortex and the posterior DMN regions, and hyperconnectivities of the posterior DMN with visual, somatosensory and motor cortices. The dichotomic dissociation of the SAD related functional connectivity changes into hypoconnectivities in the pure SAD group vs hyperconnectivities in the SAD-ADHD group leads also to the question, whether ADHD treatment can be considered an alternative for selected SAD cases.

Development of social anxiety disorder secondary to attention deficit/hyperactivity disorder (the developmental hypothesis).

Social anxiety disorder (SAD) may develop secondary to childhood attention deficit/hyperactivity (ADHD) in a subgroup of the patients with SAD. Patients pass through a number of identifiable stages of developmental pathways to SAD as they grow up. Patients with ADHD have maladaptive behaviours in social settings due to the symptoms of ADHD. These behaviours are criticized by their parents and social circle; they receive insults, humiliation and bullying. After each aversive incident, the individual feels shame and guilt. A vicious cycle emerges. The patients then develop social fears and a cognitive inhibition that occurs in social situations. The inhibition increases gradually as the fear persists and the individual becomes withdrawn. Patients start to monitor themselves and to focus on others' feedback. Finally, performative social situations become extremely stimulating for them and may trigger anxiety/panic attacks. If this hypothesis is proven, treatment of 'patients with SAD secondary to ADHD' should focus on the primary disease.

Dissociative disorders in the psychiatric emergency ward.

OBJECTIVE: The aim of this study was to determine the prevalence of dissociative disorders among emergency psychiatric admissions. METHOD: Forty-three of the 97 consecutive outpatients admitted to the psychiatric emergency unit of a university hospital were screened using the Dissociative Experiences Scale (DES). Seventeen (39.5% of the 43 evaluated) patients with a DES score above 25.0 were then interviewed with the Dissociative Disorders Interview Schedule and the Structured Clinical Interview for Dissociative Disorders. RESULTS: Fifteen emergency unit patients (34.9% of the 43 evaluated participants) were diagnosed as having a dissociative disorder. Six (14.0%) patients had dissociative identity disorder, 6 (14.0%) had dissociative disorder not otherwise specified, and 3 (7.0%) had dissociative amnesia. The average DES score of dissociative patients was 43.7. A majority of them had comorbid major depression, somatization disorder, and borderline personality disorder. Most of the patients with dissociative disorder reported auditory hallucinations, symptoms associated with psychogenic amnesia, flashback experiences, and childhood abuse and/or neglect. CONCLUSIONS: Dissociative disorders constitute one of the diagnostic groups with high relevance in emergency psychiatry.

The Presence of Childhood Attention Deficit/Hyperactivity Disorder May Be Associated With Interpersonal Sensitivity in Patients With Social Anxiety Disorder.

The goal of this study was to evaluate a possible association between childhood attention deficit/hyperactivity disorder (ADHD) and interpersonal sensitivity in patients with social anxiety disorder (SAD). The study involved 125 adult outpatients with a primary diagnosis of SAD. To evaluate childhood ADHD, the ADHD module of the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL) was used. Clinical and sociodemographic data were collected and clinical rating scales were completed. Mean total scores on the Interpersonal Sensitivity Measure were significantly higher in the group with SAD and ADHD than in the group with SAD without ADHD. Interpersonal Sensitivity Measure total scores were positively correlated with the severity of SAD symptoms and negatively correlated with mean age of onset of SAD. The presence of childhood ADHD may be associated with greater interpersonal sensitivity in patients with SAD.

Extended-release methylphenidate monotherapy in patients with comorbid social anxiety disorder and adult attention-deficit/hyperactivity disorder: retrospective case series.

BACKGROUND: The relationship between social anxiety disorder (SAD) and attention-deficit/hyperactivity disorder (ADHD) is a subject which has recently become a topic of interest for research. METHODS: In this study, 20 patients with comorbid SAD and adult ADHD who were treated with extended-release methylphenidate monotherapy were evaluated retrospectively. RESULTS: Clinical response for both ADHD and SAD symptoms was observed in 17 of 20 patients. Overall, one patient did not respond to treatment and two patients dropped out of treatment at the beginning due to adverse effects. CONCLUSION: Extended-release methylphenidate improved both SAD and ADHD symptoms and was generally well tolerated. Further studies are required to investigate the relationship between SAD and ADHD.
