RESUMO
OBJECTIVE: Most neurodegenerative dementias present with substantial overlap in clinical features. Therefore, differential diagnosis is often a challenging task necessitating costly and sometimes invasive diagnostic procedures. A promising, non-invasive and cost-effective method is the widely available electroencephalography (EEG). METHODS: Twenty-three subjects with Alzheimer's disease (AD), 28 subjects with dementia with Lewy bodies (DLB), 15 subjects with frontotemporal dementias (FTDs), and 22 healthy controls (HC) were enrolled. Nineteen channel computerized EEG recordings were acquired. Mean relative powers were calculated using the standard frequency bands. Theta/alpha ratio (TAR), theta/beta ratio (TBR), a spectral index of (alpha + beta)/(theta + delta) and an alpha reactivity index (alpha in eyes-open condition/alpha in eyes-closed condition) were also calculated. Receiver operating characteristic (ROC) analyses were performed to assess diagnostic accuracy. RESULTS: For the comparison of EEG measures across groups, we performed a multivariate ANOVA followed by univariate ANOVAs controlling for the effects of age, with post hoc tests. Theta power and TBR were increased in DLB compared to other groups. Alpha power was decreased in DLB compared to HC and FTD; and in AD compared to FTD. Beta power was decreased in DLB compared to AD and HC. Furthermore, regional analyses demonstrated a unique pattern of theta power increase in DLB; affecting frontal, central, parietal, occipital, and temporal regions. In AD, theta power increased compared to HC in parietal, occipital, and right temporal regions. TAR was increased in DLB compared to other groups; and in AD compared to HC. Finally, alpha reactivity index was higher in DLB compared to HC and FTD. In AD, EEG slowing was associated with cognitive impairment, while in DLB, this was associated with higher DLB characteristics. In the ROC analyses to distinguish DLB from FTD and AD, measures of EEG slowing yielded high area under curve values, with good specificities. Also, decreased alpha reactivity could distinguish DLB from FTD with good specificity. EEG slowing in DLB showed a diffuse pattern compared to AD, where a posterior and temporal slowing predominated. CONCLUSION: We showed that EEG slowing was satisfactory in distinguishing DLB patients from AD and FTD patients. Notably, this slowing was a characteristic finding in DLB patients, even at early stages, while it paralleled disease progression in AD. Furthermore, EEG slowing in DLB showed a diffuse pattern compared to AD, where a posterior and temporal slowing predominated. These findings align with the previous evidence of the diencephalic dysfunction in DLB.

BACKGROUND: Here, we aimed to investigate the roles of long-term potentiation-like (LTP-like) plasticity using intermittent theta burst (iTBS) protocol and resting motor threshold (rMT) in the differential diagnosis of Alzheimer's disease (AD), diffuse dementia with Lewy bodies (DLB) and frontotemporal dementia (FTD). METHOD: We enrolled 21 subjects with AD, 28 subjects with DLB, 14 subjects with FTD, and 33 elderly subjects with normal cognitive functions into the study. We recorded rMT and percentage amplitude change of motor evoked potentials (MEPs) after the iTBS protocol in each group. RESULTS: In patients with AD and DLB, the percentage amplitude change of MEPs, and rMTs were significantly lower than in healthy subjects. However, no significant difference was observed in individuals with FTD. CONCLUSION: Our findings showed that transcranial magnetic stimulation measures, particularly rMTs and LTP-like plasticity, may be potential biomarkers to distinguish between different dementia subtypes. Impaired motor cortical excitability and synaptic plasticity were more prominent in AD and DLB than in FTD. This aligns with the evidence that cortical motor networks are usually spared in FTDs in early-to-middle stages.

PURPOSE: To asses risk of new-onset impulse control disorders (ICDs) in patients with Cushing's disease (CD) who initiated cabergoline (CBG) and to determine frequency of ICDs in CBG-treated patients with CD. METHODS: This naturalistic observational study had prospective and cross-sectional arms which included patients at five referral centers based in Istanbul. Patients who were scheduled for CBG were assigned to prospective arm. These patients underwent neuropsychological tests (Barratt Impulsiveness Scale, Minnesota Impulsive Disorders Interview, Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale, Go/No-Go Task, Iowa Gambling Task, and Short Penn Continuous Performance Test) for assessment of impulsivity and psychiatric evaluations at baseline, 3, 6, and 12 months of CBG treatment. Impulsivity and new-onset ICDs were prospectively assessed. Patients with CD with current CBG treatment for ≥ 3 months and matched CBG-naïve patients with CD were included in cross-sectional arm. These patients underwent the same neuropsychological and psychiatric assessments. The impulsivity and frequency of ICDs were compared between CBG-treated and CBG-naïve patients with CD. RESULTS: The follow-up duration of prospective cohort (n = 14) was 7.3 ± 2.3 months. One patient developed major depressive episode and another patient developed compulsive gambling after CBG. We observed no significant changes in impulsivity scores during follow-up. In cross-sectional arm, CBG-treated (n = 34) and CBG-naïve patients (n = 34) were similar in impulsivity scores and frequency of ICDs [3 patients (8.8%) vs. 2 patients (5.9%) respectively, p = 1.0]. CONCLUSION: CBG-treated patients with CD appeared to have a low risk of ICDs, suggesting that CBG still holds promise as a safe agent in CD.

Depression is one of the most important reasons for psychiatric referrals in elderly patients. Geriatric depression can be chronic and is associated with an increased risk of dementia. We aimed to determine the prognosis of major depression patients and associated risk factors regarding persistence of depression. Patients who were admitted to the tertiary geriatric psychiatric outpatient unit of Istanbul University-Cerrahpasa, Cerrahpasa Faculty of Medicine, Istanbul between January and December 2018 and were diagnosed with major depression according to DSM-5 diagnostic criteria were included in the study. A structured telephone interview was conducted with between February-April 2022. For detailed clinical evaluation, Turkish version of Structured Clinical Interview for DSM-5-Disorders/Clinician Version (SCID-5/CV-TR), Telephone Cognitive Screen (T-cogS-TR), Geriatric Depression Scale (GDS), Clinical Dementia Rating Scale (CDR), Lawton-Brody Instrumental Activities of Daily Living Scale (IADL) and Beck Anxiety Inventory (BAI) were used. Of the 123 patients interviewed, 40.9% were diagnosed with major depression and 14.6% with minor depression. 43.4% showed significant anxiety and depression symptoms. Dementia developed in 14.6% of the patients. Only 29.5% of the patients recovered completely. Hypertension, orthopedic disease or arthritis, cancer, and absence of prior work experience were found to be predictors of current depression diagnosis. Geriatric depression has an unfavorable prognosis despite continued antidepressant treatment and may even serve as a prodrome for future dementia. Timely management of co-morbid medical conditions such as hypertension can potentially improve the prognosis of geriatric depression.

OBJECTIVES: Vaccination against COVID-19 emerges as an effective strategy for combating the pandemic. While many of our patients with rheumatic diseases (RD) wonder whether it is safe to get the vaccine, vaccine hesitancy is rising among the general population. We assessed the willingness to get vaccination and its probable predictors among patients with RD compared to healthcare workers and a sample from the general population. METHODS: We conducted a web-based questionnaire survey in a cross-sectional design in 3 groups of participants just before the mass vaccination program in Istanbul, Turkey. The questionnaire sought socio-demographic variables, COVID-19 related risk factors, willingness to get vaccination, and concerns and thoughts about vaccine. COVID-19 anxiety scale (CAS) was also evaluated. RESULTS: We studied in total 732 patients with RD (Group 1), 763 individuals representing general population (Group 2) and 320 hospital workers (Group 3). Dysfunctional anxiety related to COVID-19 was found in 4.9%, 3.8% and 4.1%, in Group 1, 2 and 3, respectively. Of the patients with RD, 29.2% were willing to be vaccinated, 19.0% were unwilling and 51.8% were undecided. These were somewhat similar among the general population (yes: 34.6%, no: 23.3% and unsure: 42.1%), with significantly less undecided individuals (p < 0.001). On the other hand, hospital workers were significantly more willing (yes: 52.5%, no: 20.9% and unsure: 26.6%) (p < 0.001). Main concerns were probable side effects, unknown scientific results and having no trust. Being male, older age, working in a hospital, not having contracted COVID-19 and high scores on CAS were found to be independently associated with willingness. CONCLUSIONS: The low rate of vaccine acceptance among patients with RD, as well as general population sampling is worrying. Healthcare policies should aim to implement communication, promote confidence and increase demand for COVID-19 vaccine.

We hypothesized that patients with rheumatic diseases (RD) would have increased psychological distress during the COVID-19 outbreak; therefore, assessed their psychological symptoms and changes in their routine. A web-based questionnaire survey was conducted in a cross-sectional design in three groups of participants: (1.) patients with RD, (2.) hospital workers, and (3.) high-school teachers/academic staff. Psychiatric status was evaluated using Hospital Anxiety and Depression Scale and Impact of Event Scale-Revised scale. Overall response rate was 34.7%. We studied 771 patients with RD, 535 hospital workers, and 917 teachers/academic staff. Most of the patients with RD were unwilling to go to the hospital (86%), while 22% discontinued their medications. Biological DMARDS were the most frequent drugs whose doses were altered. Only 4% were willing to take hydroxychloroquine for protection. Moreover, the frequency of anxiety (20%), depression (43%), and post-traumatic stress (28%) among patients with RD were found to be comparable to that found among the teachers/academic staff (23%, 43% and 29%, respectively), whereas significantly less than that observed among the hospital workers (40%, 62%, and 46%, respectively) (p < 0.001). Female gender, use of social media, having a comorbid disease, or a psychiatric disorder were found to be independently associated with psychiatric symptoms in total study population. The majority of the patients were unwilling to attend outpatient visits and one-fifth skipped or stopped their immunosuppressive agents. Psychiatric symptoms in patient's and teacher's populations were of considerable clinical concern, despite being significantly lower than that observed among the hospital workers.

Akathisia is a sensori-motor phenomenon which is generally encountered as an adverse effect of antidopaminergic medications suggesting involvement of dopaminergic pathways. We recently showed nociceptive flexor reflex was altered in akathisia as compared to restless legs syndrome and therefore, these findings may indicate co-involvement of pathways other than dopaminergic ones. To examine functional status of different pathways, we investigated auditory startle reflex (ASR), startle response to somatosensory input (SSS), and trigemino-cervical reflex (TCR) in a group of patients with akathisia. Consecutive seven patients with drug-induced akathisia and age- and gender-matched healthy subjects were prospectively included in the study. The diagnosis was made by appropriate clinical criteria. Brainstem reflexes, ASR, SSS, and TCR were examined in all participants. The probability, onset latency, amplitude, and duration were measured and compared between groups. The probability and amplitudes of ASRs were significantly increased and durations of ASRs and TCRs were prolonged in the patient group. Latencies of all responses as well as patterns of startle responses were similar between groups. The results reveal hyperactivity of the ASR and TCR in drug-induced akathisia. Hyperactive ASRs and TCRs also confirm suprasegmental hypodopaminergic state in akathisia. Although we keep in mind the confounding effects due to concurrent antidopaminergic treatments and the small sample group, we speculate that hyperactive ASRs and TCRs might be related to deficient control by forebrain and limbic-mainly amygdala-network in patients with drug-induced akathisia.

PURPOSE: To determine the physical status and intelligence scores of children of acromegalic mothers and to compare them with those of children from mothers without acromegaly. METHODS: Six women with acromegaly who became pregnant under follow-up between 2010 and 2014 and their 16 children (group A) were assessed and compared with 16 children of healthy women (group B) and 15 children of women with prolactinoma (group C). The physical examinations of children were performed by the department of pediatric endocrinology and intelligence quotient (IQ) testing was undertaken by adult and pediatric psychiatry departments, using appropriate scales for their ages. RESULTS: Six of the 16 children (girls/boys: 7/9) were born after the diagnosis of acromegaly. Five of the 6 pregnancies occured when the patients were taking somatostatin analogs, none continued taking the drugs during pregnancy. The mean IQ of groups A, B, and C were 106.4 ± 12.5, 105.3 ± 12.5, and 103.2 ± 16.1 respectively (p > 0.05). The mean ages, birth percentiles, recent weight and height standard deviation scores were similar between groups (p > 0.05). Two siblings from group A and 1 child from group B were large for gestational age at birth. At recent follow-up, two children from group A were found tall for their age and one from group C was short for his age and was placed under the care of pediatric endocrinology clinic. CONCLUSIONS: Pregnancies in acromegaly seems to be uneventful and the general health status and IQ scores of children from women with and without acromegaly were found similar.

BACKGROUND: The severity of psychopathology cannot fully explain deficits in the multi-dimensional construct of insight. AIMS: The aim of this study was to evaluate the correlates and associations of clinical and cognitive insight in patients in an acute phase of psychosis and to analyse the impact of acute treatment on these variables. METHODS: This study examined 47 inpatients who were recently hospitalized with acute exacerbation of schizophrenia. All subjects were assessed at both admission and discharge with the Positive and Negative Syndrome Scale (PANSS), Schedule for the Assessment of Insight-Expanded Version (SAI-E), Beck Cognitive Insight Scale (BCIS), and a neurocognition battery. RESULTS: Patients with schizophrenia gained clinical insight after treatment. Cognitive insight did not change significantly after treatment. Insight showed significant negative correlations with positive symptoms and general psychopathology, but not with negative symptoms. Clinical insight was not associated with neuropsychological functioning in this cohort. CONCLUSION: Gaining clinical insight in the acute phase of illness was associated with the remission of positive symptoms, but not with neuropsychological functioning. Some significant correlations between clinical and cognitive insights were detected, which suggests that cognitive insight contributes to clinical insight but is not treatment-dependent. Long-term treatment may be required to understand the contribution of insight to the outcome of patients with schizophrenia.

The aim of this study is to evaluate the safety and effectiveness of rapid clozapine titration in patients with schizophrenia in hospital settings. We conducted a retrospective two-center cohort study to compare the safety and effectiveness of clozapine with different titration rates in treatment-refractory patients with schizophrenia. In the first center, clozapine was started at 25-50 mg followed by 50-100 mg as needed every 6 h on day 1, followed by increases of 50-100 mg/day. In the second center, titration was slower; clozapine initiated with 12.5-50 mg on day 1 followed by increases of 25-50 mg/day. The number of days between starting of clozapine until discharge was shorter in the rapid titration group (22.4 ± 8.72 vs 27.0 ± 10.5, p = 0.1). Number of days of total hospital stay were significantly shorter in the rapid titration group (29.6 ± 10.6 vs 41.2 ± 14.8, p = 0.002). Hypotension was more common in the rapid titration group and one patient had suspected myocarditis. Rapid clozapine titration appeared safe and effective. The length of stay following initiation of clozapine was shorter in the rapid-titration group, although this was not statistically significant. However starting clozapine earlier together with rapid titration has significantly shortened the length of hospital stay in patients with treatment refractory schizophrenia.

We investigated trends over a decade in the prescription of lithium, antiepileptics, and antipsychotic agents at discharge for patients hospitalised for acute mania. We conducted a retrospective review of medical records for 165 inpatients with acute mania who had been hospitalised in Cerrahpasa Faculty of Medicine, Department of Psychiatry during 2001-2002 and 2011-2012. Among 165 patients, prescription of olanzapine at discharge increased from 3 to 46 % (p < 0.001), while prescription of haloperidol decreased from 55 to 21 % (p < 0.001). Use of other atypical antipsychotics did not change significantly (risperidone decreased from 14 to 11 %, p = 0.5; quetiapine increased from 10 to 16 %, p = 0.2). Use of valproate, carbamazepine, and lithium did not change significantly. Use of electroconvulsive therapy in acute mania decreased by half from 27 to 13 % (p = 0.02). Typical antipsychotics alone or in combination with antiepileptics were the most common treatment regimen at discharge at 2001-2002; while 10 years later, they had been largely replaced by lithium or antiepileptics combined with second generation antipsychotics. Antipsychotic agents remained to be an important component of acute treatment of mania in our practice.

BACKGROUND: Dementia encompasses a range of neurodegenerative disorders characterized by cognitive decline and functional impairment. The identification of reliable biomarkers is essential for accurate diagnosis and gaining insights into the mechanisms underlying diseases. OBJECTIVE: This study aimed to investigate the plasma biomarker profiles associated with Brain- Derived Neurotrophic Factor (BDNF), Oxytocin, Neuronal Pentraxin-1 (NPTX1), Triggering Receptor Expressed on Myeloid Cells 2 (TREM2), Tumor Necrosis Factor-alpha (TNF-alpha), Interleukin- 1 (IL-1), and Prolactin in Alzheimer's disease (AD), dementia with Lewy bodies (DLB), frontotemporal dementias (FTD), and healthy controls. METHODS: Serum levels of the aforementioned biomarkers were analyzed in 23 AD, 28 DLB, 15 FTD patients recruited from outpatient units, and 22 healthy controls. Diagnostic evaluations followed established criteria, and standardized clinical tests were conducted. Blood samples were collected and analyzed using ELISA and electrochemiluminescence immunoassay methods. RESULTS: Serum BDNF and oxytocin levels did not significantly differ across groups. NPTX1, TREM2, TNF-alpha, and IL-1 levels also did not show significant differences among dementia groups. However, prolactin levels exhibited distinct patterns, with lower levels in male DLB patients and higher levels in female AD patients compared to controls. CONCLUSION: The study findings suggest potential shared mechanisms in dementia pathophysiology and highlight the importance of exploring neuroendocrine responses, particularly in AD and DLB. However, further research is warranted to elucidate the role of these biomarkers in dementia diagnosis and disease progression.
RESUMO
OBJECTIVES: To evaluate the microstructural integrity of brain white matter tracts in patients with Neuro-Behcet's syndrome (NBS) and Behcet's syndrome (BS) without neurological manifestations using diffusion tensor imaging (DTI) and to investigate potential utility of DTI as a surrogate biomarker of neurocognitive functioning and disease severity. METHODS: This cross-sectional study comprised 34 NBS patients and 32 BS patients without neurological involvement, identified based on the International Study Group of the Behcet's disease (ISGBD) and the International Consensus Recommendation (ICR) criteria, as well as 33 healthy controls. Cognitive functions, including attention, memory, language, abstraction, executive control, visuospatial skills, and sensorimotor performance were assessed using standardized questionnaires. DTI data were analyzed using tract-based spatial statistics (TBSS) and automated probabilistic tractography to investigate inter-group differences. Subsequently, correlations between tensor-derived parameters of white matter tracts, neurocognitive test scores, and disease severity measures were examined. RESULTS: DTI revealed decreased fractional anisotropy and increased radial diffusivity, mean diffusivity, and axial diffusivity in both supratentorial and infratentorial white matter in NBS patients, indicating widespread loss of microstructural integrity. Moreover, this loss of integrity was also observed in BS patients without neurological manifestations, albeit to a lesser extent. In NBS patients, certain white matter tracts, including cingulum bundle, were associated with poor cognitive performance across multiple domains and disease severity. DISCUSSION: DTI findings might potentially serve as a neuroimaging marker to predict the extent of neurocognitive impairment and disease severity associated with central nervous system involvement in BS.
RESUMO
CONTEXT: Dopamine agonist (DA)-induced impulse control disorder (ICD) represents a group of behavioral disorders that are increasingly recognized in patients with prolactinoma. OBJECTIVE: We aimed to examine the genetic component of the underlying mechanism of DA-induced ICD. METHODS: Patients with prolactinoma receiving dopamine agonist (cabergoline) treatment were included in the study. These patients were divided into 2 groups: patients who developed ICD due to DA and patients who did not. Patients were evaluated for polymorphisms of the DRD1, DRD3, COMT, DDC, GRIN2B, TPH2, OPRK1, OPRM1, SLC6A4, SLC6A3, HTR2A genes. RESULTS: Of the 72 patients with prolactinoma using cabergoline, 20 were diagnosed with ICD. When patients with and without ICD were compared according to genotype frequencies, OPRK1/rs702764, DRD3/rs6280, HTR2A/rs6313, SLC6A4/rs7224199, GRIN2B/rs7301328, TPH2/rs7305115, COMT/rs4680, DRD1/rs4532 polymorphisms significantly increased in patients with DA-induced ICD. CONCLUSION: Our results show that multiple neurotransmission systems affect DA-induced ICD in patients with prolactinoma.

OBJECTIVE: In parkinsonian syndromes, presentations other than current diagnostic criteria are considered atypical findings. Our goal was to identify and describe the frequency and features of uncommon manifestations of atypical parkinsonian syndromes within our group. METHODS: We retrospectively retrieved the medical records of all patients admitted to our clinic with parkinsonism between January 2011 and January 2022. We only included patients with atypical parkinsonian syndromes, in which the diagnosis was based on current clinical criteria. We retrospectively analyzed neurological, psychiatric, radiological, and electrophysiological characteristics. Typical and atypical features were classified according to the current clinical criteria and previous reports. RESULTS: We determined 51 patients with atypical parkinsonian syndromes; 46 were included, whereas five were excluded due to insufficient follow-up. The probable diagnoses were multiple system atrophy (MSA, n = 19), dementia with Lewy bodies (DLB, n = 10), frontotemporal dementia (FTD, n = 10), corticobasal syndrome (CBS, n = 3), progressive supranuclear palsy (PSP, n = 4). The prevalence of atypical findings was similar among different types of atypical parkinsonian syndromes (p = 0.847). Atypical findings were eyelid myoclonus, double vision in MSA; ataxia, myoclonus, and a typical hummingbird sign on MRI in DLB; pyramidal findings and family history in FTD; early onset, family history, and onset with psychiatric findings in PSP-like phenotype. Genetic causes were identified in the FTD-like phenotype with pyramidal findings, whereas symptom onset was early with myoclonus in the PSP-like phenotype. CONCLUSION: Atypical findings such as abnormal saccades, myoclonus, and ataxia may be a part of degenerative syndromes. However, family history, onset at an earlier age, and specific neurological findings suggest genetic syndromes.

Neurological soft signs (NSSs) and minor physical anomalies (MPAs) are consistently found at higher rates in individuals with schizophrenia compared to healthy controls. However, limited research has been conducted on these traits among the biological relatives of these patients. We aimed to identify the possible origins of these traits in schizophrenia by exploring them in patients with schizophrenia, their healthy siblings and normal controls. Ninety-six patients with schizophrenia, their 66 non-psychotic siblings and 52 healthy subjects were studied. Measures included the Neurological Evaluation Scale, a structured examination for detection of minor physical anomalies, stroop and verbal fluency tests for cognitive assessment, and scales for assessment of disease severity in patients; the Scale for the Assesment of Negative Symptoms and the Scale for the Assesment of Positive Symptoms. Increased rates of NSSs and high MPA scores were found in both the patients and their siblings as compared to normal controls. MPAs in several body regions were similar (eyes, ears, hands and feet) or correlated (innercanthal width and head circumference) between patients and their respective siblings. However, there was little similarity in palate and tongue anomalies between these subjects. These results suggest that NSSs and MPAs might represent two distinct markers of risk for schizophrenia. MPAs at different locations may also represent distinct pathological processes, such that palate and tongue abnormalities are more likely to represent non-familial rather than familial factors compared to other abnormalities.

OBJECTIVES: In an attempt to control the new coronavirus pandemic, many countries have taken unprecedented measures, such as extensive social distancing and total lockdowns of cities. Kidney transplant recipients have an increased risk for infectious diseases, including viral infections. In this study, we aimed to investigate the effects of population-wide infection control measures on the mood statuses of kidney transplant recipients. MATERIALS AND METHODS: We used an electronic survey tool to collect demographic and sociocultural data. Additionally, in the same survey, we used 2 questionnaires (the Profile of Mood States and the Hospital Anxiety and Depression Scale) to measure mood statuses of kidney transplant recipients. We also examined a control group and selected eligible participants according to age- and sex-based propensity score matching. RESULTS: We analyzed the data of 308 participants: 154 kidney transplant recipients (mean age of 39.9 ± 10.6 years; 57.1% male) and 154 control participants (mean age of 39.1 ± 10.5; 57.1% male). With regard to the Profile of Mood States questionnaire, total scores and all subscale scores, excluding vigor, were significantly lower in kidney transplant recipients than in the control group, a finding consistent with a better mood status. We found similar findings in anxiety and depression scores for the Hospital Anxiety and Depression Scale questionnaire. CONCLUSIONS: Kidney transplant recipients seem to be resilient to the psychological stress induced by social distancing and lockdown periods. Strict adherence to infection control measures is purposefully suggested in this infection-prone population.
RESUMO
Patients hospitalized with COVID-19 are at risk of developing many neuropsychiatric disorders, due to the effects of the disease on the brain and the psychosocial pressures of having the disease. The aim of the present study was to evaluate the characteristics and outcomes of patients who were hospitalized with a diagnosis of COVID-19, who underwent psychiatric consultations. The medical records of 892 patients hospitalized due to COVID-19 and the 89 among them who requested psychiatric consultations were analyzed retrospectively. After the psychiatric consultations, patients were most frequently diagnosed with delirium (38.2 %), adjustment disorder (27.0 %), depressive disorder (19.1 %) and anxiety disorder (11.2 %). Patients with delirium had longer hospital stays (p < 0.001), were transferred more frequently to intensive care units (p < 0.001), and had higher mortality rates during their hospital stays (p < 0.001), than all other patients. The need for oxygen (p < 0.001) and mechanical ventilation (p < 0.001) was also significantly higher in delirium patients, as well as in patients who received other psychiatric diagnoses. Neuropsychiatric disorders develop in patients receiving inpatient treatments in COVID-19 wards, and these disorders negatively affect the prognosis of COVID-19. Our findings suggest that the presence of neuropsychiatric disorders in in-patients with COVID-19 might be associated with the negative outcomes of the disease.

We investigated the psychiatric symptomatology and the protracted symptoms in patients who had recovered from the acute COVID-19 infection. Two hundred and eighty-four patients completed a web-based or a paper survey on socio-demographic and clinical data. The psychiatric status was assessed using Impact of Events Scale-Revised (IES-R), Hospital Anxiety and Depression Scale (HADS), Pittsburgh Sleep Quality Index (PSQI), and MINI suicidality scale. Patients completed a checklist for the protracted symptoms that were experienced after the acute infection. After a mean of almost 50 days following the diagnosis, 98 patients (34.5%) reported clinically significant PTSD, anxiety, and/or depression, with PTSD being the most common condition reported (25.4%). One hundred and eighteen patients (44.3%) reported one or more protracted symptom(s). Predictors of PTSD symptom severity were the female gender, past traumatic events, protracted symptoms, stigmatization, and a negative view on the COVID-19 pandemic. PTSD symptom severity was the sole independent predictor of the protracted symptoms. Our results suggest that COVID-19 patients are prone to substantial psychological distress in the first few months after the infection. The protracted symptoms were frequent in this period, and these were closely related to the posttraumatic symptoms.
