Plasma and CSF neurofilament light chain distinguish neurodegenerative from primary psychiatric conditions in a clinical setting.

People with neurodegenerative disorders (ND) frequently face diagnostic delay and misdiagnosis. We investigated blood and cerebrospinal fluid (CSF) neurofilament light chain (NfL) to distinguish ND from primary psychiatric disorders (PPD), a common challenge in clinical settings. Plasma and CSF NfL levels were measured and compared between groups, adjusting for age, sex, and weight. A total of 337 participants were included: 136 ND, 77 PPD, and 124 Controls. Plasma NfL was 2.5-fold elevated in ND compared to PPD and had strong diagnostic performance (area under the curve, [AUC]: 0.86, 81%/85% specificity/sensitivity) that was comparable to CSF NfL (2-fold elevated, AUC: 0.89, 95%/71% specificity/sensitivity). Diagnostic performance was especially strong in younger people (40-<60 years). Additional findings were cutoffs optimized for sensitivity and specificity, and issues important for future clinical translation. This study adds important evidence for a simple blood-based biomarker to assist as a screening test for neurodegeneration and distinction from PPD, in clinical settings. NfL levels were significantly higher in ND versus PPD. Plasma NfL showed strong diagnostic performance, comparable to CSF NfL, to distinguish ND from PPD. Diagnostic performance was higher in younger people, where diagnostic challenges are greater. Further research is needed on analytical and reference range factors, for clinical translation. These findings support a simple screening blood test for neurodegeneration.

A Baseline Model of PTSD From the ACES Cohort.

Post-traumatic stress disorder (PTSD) is a primary military psychiatric condition with complex etiology including strong genetic and/or environmental influences. Environmental influences and demographics can play a role in supporting underlying genetic traits for clinical utility evaluation as risk modifying factors. We are undertaking an IRB approved study to evaluate polygenic scores of PTSD risk in the adverse childhood experience and serotonin (ACES) transporter cohort. Baseline demographic characteristics and statistical modeling of 291 active duty service members from ACES cohort were used and excluded individuals with traumatic brain injury-induced loss of consciousness, pre-deployment PTSD or anxiety disorder, and pre-deployment prescription of antidepressants or psychoactive medications. Summary of categorical and numerical variables were evaluated using chi-square and t-test, respectively. We model PTSD risk and associated scores using linear and logistic regressions. The ACES subset was 79.1% males, multi-ancestry, and mean age of 38.3 years. Most PTSD individuals received behavioral therapy (89.6%) and/or prescribed antidepressants (67%) had higher scores in ACES, combat exposure scales, PTSD checklist military version, neurobehavioral symptom inventory, Pittsburg sleep quality index, insomnia severity index, and composite autonomic symptom score surveys and were less likely to expect future deployment. A positive correlation between age, total months deployed, ACES, CES, PCL-M, and positive-PTSD diagnosis were consistent but not in older individuals, who were more likely and frequently deployed although increasing risk for combat exposure. Demographic characteristics of the ACES cohort fit a coherent model of risk for PTSD to evaluate polygenic scores. Additional research is merited to understand PTSD effects on these confounding factors.

Skin Diseases in Patients With Primary Psychiatric Conditions in Northern India: A Cross-Sectional Study.

The relationship between skin diseases and psychiatric illnesses is bi-directional and is manifested as cause and effect. Psychiatric disorders such as stress, anxiety, and depression are seen to be instrumental in the development and progression of dermatological diseases on one hand, while on the other hand, cosmetic disfigurement caused by dermatological diseases is responsible for psychological distress in patients. The present study was conducted to investigate the spectrum of dermatological disorders in psychiatric patients to offer them holistic treatment andprovide them with a better quality of life. This cross-sectional, observational study wasconducted at a tertiary medical care center. A total of 170 psychiatric patients referred to the dermatology department for different dermatological manifestations were enrolled in the study. A demographic profile of the patients was done, and an association between dermatological diseases and psychiatric illnesses was done. Out of 170 study participants, 88 (51.8%) were females, and the rest (82, 48.2%) were males.A total of 13 major types of dermatological conditions were noted; among them, fungal infection (43, 25.3%) was the most common, followed by eczema (18, 10.6%), parasitic infestation (17, 10.0%), pigmentary disorder (13, 7.6%), acne (11, 6.5%), bacterial infection (11, 6.5%), pruritic disorder (11, 6.5%), hair disorder (9, 5.3%), drug reaction (9, 5.3%), papulosquamous disorder (7, 4.1%), and viral infection (6, 3.5%). Skin conditions other than the above-mentioned were present in 15 (8.8%) patients.The most common psychiatric illness in the present study was major depressive disorder (41, 24.1%), followed by generalized anxiety disorder (38, 22.4%) and psychosis not otherwise specified (34, 20.0%). Other psychiatric illnesses included in the study were bipolar affective disorder (22, 12.9%), schizophrenia (18, 10.6%), obsessive-compulsive disorder (12, 7.1%), and mixed anxiety depressive disorder (5, 2.9%). The findings of the present study depict that psychiatric patients with dermatological manifestations show a spectrum of dermatological conditions, primarily of infectious (fungal, parasitic, or viral) nature. This might be associated with a relatively poor hygienic status of psychiatric patients and thus their increased susceptibility to these disorders. Most of the time, the susceptibility to these skin conditions seemed to be opportunistic and unaffected by the type, duration, and level of control of psychiatric illness.

New onset gender dysphoria in bipolar affective disorder - A case series

Gender confusion in the context of mania is very less frequently described in the literature. The actuality of a primary psychiatric condition in gender identity complaint has significant bearing on the applicable operation and prognostic. This case series describes cases of bipolar affective complaint presenting in a manic occasion whose mania was marked by hypersexuality and the desire to be of opposite gender. Both of these symptoms resolved with treatment of the manic occasion. Case 1 describes a 17-year-old male presenting with an episodic illness, with current manic episode. He is currently interested in boys and has started enjoying feminine activities. Upon treatment, his symptoms showed improvement. Case 2 describes a 22-year-old gay male, with a total duration of 7 years, current episode mania. Now, he is considering himself a lesbian and feels he is mentally a modern female. After 4 months of treatment, there was significant improvement in his complaints and he stopped cross-dressing as a female. Case 3 shows a 21-year-old female, with manic episode. After 1 month, the patient began acting and speaking more like a boy. The patient has shown improvement while taking lithium 900 mg, divalproex sodium 1000 mg, risperidone 6 mg, and chlorpromazine 150 mg. Gender dysphoria occurring along with a psychotic episode and resolving with management of the primary psychiatric disorder are rarely recorded. The central issue in similar cases is a proper workup and diagnosis. Psychiatrists should be aware of this scenario so that proper treatment strategies for gender incongruence can be planned and not be brushed aside as “just another symptom.”

Psychodermatological Disorders in Patients With Primary Psychiatric Conditions: Cross-Sectional Study.

Psychodermatological disorders (PDs) and their associations with mental health problems are one of the most frequent research themes in dermatology outpatient settings. Surprisingly, very few studies have been conducted to evaluate PDs among patients with primary psychiatric conditions. As such, the relationship between preexisting psychiatric conditions and comorbid PDs is underrepresented in the literature. This study examined the prevalence and distribution of PDs among adults with primary psychiatric conditions and determined their association with underlying psychiatric diagnoses. We conducted a cross-sectional analysis at a tertiary health care facility in southwestern Nigeria. Comorbid PDs were identified and classified using preexisting classification systems. A bivariate analysis was conducted to determine the association between PDs and underlying psychiatric conditions. The level of statistical significance was set at P<.05. The study included 107 patients with mental health disorders, of whom 64 (59.8%) were female. The mean age of the patients was 40.73 (SD 13.08) years. A total of 75 (75/107, 70%) patients had at least one comorbid PD. The prevalence of PDs was highest in patients with affective disorders (15/20, 75%) and least in those with schizophrenia (45/66, 68%). PDs associated with delusions or hallucinations and somatoform symptoms were 9 and 13 times more frequent in patients with anxiety disorders compared to those with other psychiatric conditions (P=.01; odds ratio [OR] 9.88, 95% CI 1.67-58.34 and P=.003; OR 13.13, 95% CI 2.34-73.65), respectively. In contrast, patients with schizophrenia were significantly less likely to be diagnosed with dermatoses resulting from delusions or hallucinations (P=.002; OR 0.04, 95% CI 0.00-0.75). A weak but significant negative association was also found between psychophysiological PDs and anxiety disorders (ϕ=-0.236; P=.02). This study provides important insights into the overwhelming burden of psychodermatological conditions in patients with mental health disorders and specific associations with underlying psychiatric diagnosis.

Exploring real-world symptom impact and improvement in well-being domains for tardive dyskinesia in VMAT2 inhibitor-treated patients via clinician survey and chart review.

Two vesicular monoamine transporter 2 (VMAT2) inhibitors are approved in the United States (US) for the treatment of tardive dyskinesia (TD). There is a paucity of information on the impact of VMAT2 inhibitor treatment on patient social and physical well-being. The study objective was to elucidate clinician-reported improvement in symptoms and any noticeable changes in social or physical well-being in patients receiving VMAT2 inhibitors. A web-based survey was offered to physicians, nurse practitioners, and physician assistants based in the US who prescribed valbenazine for TD within the past 24 months. Clinicians reported data from the charts of patients who met the inclusion criteria and were allowed to recall missing information. Respondents included 163 clinicians who reviewed charts of 601 VMAT2-treated patients with TD: 47% had TD symptoms in ≥2 body regions, with the most common being in the head or face and upper extremities. Prior to treatment, 93% of patients showed impairment in ≥1 social domain, and 88% were impaired in ≥1 physical domain. Following treatment, among those with improvement in TD symptoms (n = 540), 80% to 95% showed improvement in social domains, 90% to 95% showed improvement in physical domains, and 73% showed improvement in their primary psychiatric condition. In VMAT2-treated patients with TD symptom improvement, clinicians reported concomitant improvement in psychiatric disorder symptoms and in social and physical well-being. Regular assessment of TD impact on these types of domains should occur simultaneously with movement disorder ratings when evaluating the value of VMAT2 inhibitor therapy.

The Primary Psychiatric Conditions: Clinical Characteristics

Abstract Primary psychiatric conditions are those conditions, wherein the cutaneous manifestations are secondary to functional psychopathology in the brain. These comprise of psychiatric disorders with dermatologic manifestations and include conditions such as dermatitis artefacta, delusions of parasitosis, obsessive–compulsive disorders, body-focused repetitive behavior disorders, or somatoform disorders. Herein, we describe the clinical features and diagnostic methods of the individual primary psychiatric conditions, most of which have definitive diagnostic criteria in Diagnostic and Statistical Manual of Mental Disorders, and discuss the differential diagnoses encountered in clinical practice, in brief.

1020 Modafinil Induced Psychosis

Abstract Introduction Modafinil has been used for the treatment of numerous different conditions, including daytime somnolence (EDS). Modafinil is a non-amphetamine central nervous system (CNS) stimulant with wakefulness-promoting properties. There have been few reported cases of psychosis associated with modafinil use, however a large majority of those were seen in patients with a history of primary psychiatric disturbances. Report of case(s) We present a case of a 48 year old female coming for evaluation of excessive daytime somnolence. She completed polysomnography and a multi sleep latency test (MSLT) which revealed mildly elevated AHI, but no sleep onset rapid eye movements (SOREMPs). A diagnosis of idiopathic hypersomnia was subsequently made and 200mg of modafinil up to twice daily was prescribed for her. Patient initially tolerated the modafinil well, however she began having delusions and she subsequently required psychiatric evaluation. These delusions primarily consisted of her believing she was under surveillance and had conspiracy theories against her. She also described having auditory hallucinations as well, especially voices telling her about these conspiracy theories. She also demonstrated poor insight into her medical condition as she refused to discontinue modafinil. Upon evaluation, routine labs including complete blood count, chemistry profile and urine drug screens were completed to rule out any secondary causes of psychosis. It was therefore recommended by psychiatry to discontinue modafinil as there was concern that the delusions were occurring secondary to medication use. The patient's psychotic delusions seemed to dissipate after this. A multidisciplinary meeting was held regarding management of patients' excessive daytime sleepiness (EDS) and a decision was made to begin the patient on pitolisant, a histamine receptor antagonist. The patient was able to achieve great benefit with this medication. Conclusion The presented case illustrates a patient who began having psychosis after beginning modafinil 200mg twice daily. Psychosis is a much more rare side of modafinil and providers should become aware of it. Therefore, patients who are prescribed modafinil should be carefully followed for psychosis development, even when they are previously healthy and have no history of any primary psychiatric conditions.

Acute Psychosis

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

From CoNFLict to Confidence: Solving a Diagnostic Dilemma Using Neurofilament Light – A Case Report

Distinguishing neurodegenerative from primary psychiatric conditions is often challenging for clinicians, particularly when assessing older people presenting with neuropsychiatric symptoms. Measurement of fluid biomarkers of neurodegeneration is an emerging approach offering improved diagnostic accuracy. This report explores the use of emerging fluid biomarkers to address diagnostic challenges, framed around a case where the diagnosis of delirium with dementia was revised based on biomarker analysis, enabling treatment of a primary mood disorder with disabling psychiatric symptoms.

Thermal grill illusion of pain in patients with chronic pain: a clinical marker of central sensitization?

The thermal grill illusion of pain (TGIP) is a paradoxical burning pain sensation elicited by the simultaneous application of innocuous cutaneous warm and cold stimuli with a thermode ("thermal grill") consisting of interlaced heated and cooled bars. Its neurophysiological mechanisms are unclear, but TGIP may have some mechanisms in common with pathological pain, including central sensitization in particular, through the involvement of N-methyl- d -aspartate receptors. However, few studies have investigated TGIP in patients with chronic pain and its clinical relevance is uncertain. We hypothesized that the TGIP would be increased in comparison with controls in patients with fibromyalgia or irritable bowel syndrome, which are regarded as typical "nociplastic" primary pain syndromes related to changes in central pain processing. We compared the sensations elicited by a large range of combinations of temperature differentials between the warm and cold bars of a thermal grill applied to the hand between patients with fibromyalgia (n = 30) or irritable bowel syndrome (n= 30) and controls (n = 30). The percentage of TGIP responses and the intensity and unpleasantness of TGIP were significantly greater in patients than controls. Furthermore, positive correlations were found between TGIP intensity and clinical pain intensity and between TGIP intensity and the cold pain threshold measured on the hand. These results are consistent with our working hypothesis of shared mechanisms between TGIP and clinical pain mechanisms in patients with nociplastic chronic pain syndromes and suggest that TGIP might represent a clinical marker of central sensitization in these patients.

Malignant Catatonia: A Review for the Intensivist.

Catatonia is a clinical syndrome characterized by psychomotor, neurological and behavioral changes. The clinical picture of catatonia ranges from akinetic stupor to severe motoric excitement. Catatonia can occur in the setting of a primary psychiatric condition such as bipolar disorder or secondary to a general medical illness like autoimmune encephalitis. Importantly, it can co-occur with delirium or coma. Malignant catatonia describes catatonia that presents with clinically significant autonomic abnormalities including change in temperature, blood pressure, heart rate, and respiratory rate. It is a life-threatening form of acute brain dysfunction that has several motoric manifestations and occurs secondary to a primary psychiatric condition or a medical cause. Many of the established predisposing and precipitating factors for catatonia such as exposure to neuroleptic medications or withdrawal states are common in the setting of critical illness. Catatonia typically improves with benzodiazepines and treatment of its underlying psychiatric or medical conditions, with electroconvulsive therapy reserved for catatonia refractory to benzodiazepines or for malignant catatonia. However, some forms of catatonia, such as catatonia secondary to a general medical condition or catatonia comorbid with delirium, may be less responsive to traditional treatments. Prompt recognition and treatment of catatonia are crucial because malignant catatonia may be fatal without treatment. Given the high morbidity and mortality associated with malignant catatonia, intensivists should familiarize themselves with this important and under-recognized condition.

Acute medical workup for new-onset psychosis in children and adolescents: A retrospective cohort.

No consensus exists about which medical testing is indicated for youth with new-onset psychotic symptoms. We conducted a chart review of youths aged7-21 years who were medically hospitalized for workup of new-onset psychotic symptoms from January 2017 through September 2020 in a free-standing children's hospital. The sample included 131 patients. At discharge, 129 (98.5%; 95% confidence interval [CI]: 94.5-99.8) were diagnosed with a primary psychiatric condition, 1 was diagnosed with levetiracetam-induced psychosis, and 1 with seronegative autoimmune encephalitis. Notably, 33 (25.2%; 95% CI: 18.0-33.5) had incidental findings unrelated to psychosis, 14 (10.7%; 95% CI: 6.0-17.3) had findings that required medical intervention but did not explain the psychosis, 12 (9.2%; 95% CI: 4.8-15.5) had a positive urine drug screen, and 4 (3.1%; 95% CI:0.8-7.6) had a neurological exam consistent with conversion disorder. In conclusion, extensive medical testing in the acute setting for psychosis had a low yield for identifying medical etiologies of new-onset psychotic symptoms.

A review of the diagnosis and management of pediatric psychodermatologic conditions: Part II.

Pediatric psychodermatologic conditions encompass both primary dermatologic conditions with psychiatric comorbidities and primary psychiatric conditions with self-induced dermatologic manifestations. Detection, diagnosis, and management of primary psychiatric conditions with dermatologic manifestations are challenging due to patient-perceived stigma and lack of educational opportunities for dermatology providers. This two-part series highlights the most up-to-date evidence-based data and management techniques of some of the more common dermatoses of primary psychiatric conditions in children. Part I includes trichotillomania, skin picking disorder, and onychophagia, and part II covers dermatitis artefacta, body dysmorphic disorder, and delusions of parasitosis by proxy, with special considerations for family dynamics.

The Psychiatric Misdiagnosis of Behavioral Variant Frontotemporal Dementia in a Colombian Sample.

Objective: To describe the demographic characteristics, initial psychiatric diagnoses, and the time to reach a diagnosis of probable behavioral variant frontotemporal dementia (bvFTD) in a public psychiatric hospital in Cali, Colombia.Methods: We retrospectively reviewed the medical records of 28 patients who were diagnosed with probable bvFTD based on a multidisciplinary evaluation that included a structural MRI, neuropsychological testing, functional assessment, and neurological exam. Prior to this evaluation, all patients were evaluated by a psychiatrist as part of their initial consultation at the hospital. The initial consultation included the Neuropsychiatric Inventory and diagnoses based on the DSM-V. Demographics, clinical features, and initial psychiatric misdiagnoses were extracted from clinical records and summarized in the full sample and by gender.Results: The study sample had a mean education of 10.0 years (SD = 4.9) and 68.0% were female. In the full sample, 28.6% were initially diagnosed with dementia, and 71.4% with a psychiatric disorder. The psychiatric diagnosis at initial consultation differed by gender. Women were most likely to be diagnosed with depression (26.3%) or bipolar disorder (26.3%), while the men were most likely to be diagnosed with anxiety (33.3%) or a psychotic disorder (22.2%). Psychotic symptoms were common (delusions, 60.7% and hallucinations, 39.3%), and the pattern of neuropsychiatric symptoms did not differ by gender.Conclusions: This is one of few case series of bvFTD in a Colombian population, where bvFTD is a recognizable and prevalent disorder. In this psychiatric hospital, the majority of patients with bvFTD were initially diagnosed with a primary psychiatric condition. There was a gender difference in psychiatric diagnosis, but not in neuropsychiatric symptoms. In this sample, the rate of psychiatric misdiagnosis, as well as the psychotic symptoms, were higher compared to rates described in other countries. These results highlight the need for interventions to improve bvFTD diagnosis in under-represented populations.

Novel neurostimulation approaches: Focus on neuropsychiatric symptoms

Neuropsychiatric symptoms (NPS) such as depression, apathy and agitation are common in neurocognitive disorders such as Alzheimer's disease (AD) and its prodrome, Mild Cognitive Impairment (MCI). Importantly, the presence of NPS is a prognostic indicator of future decline in MCI and AD and reduces quality of life in both patients and caregivers. Pharmacological interventions for NPS in neurocognitive disorders have not been shown to be effective and moreover, often have unfavourable side effect profiles for older adults due to age-related changes in pharmacokinetics and pharmacodynamics and the presence of comorbid medical conditions. Non-pharmacological approaches such as neurostimulation are increasingly being applied to treat primary psychiatric and neuropsychiatric conditions and hold promise for treatment of NPS in neurocognitive conditions, both from a symptom management point of view, and as a potential disease-modifying intervention for neurocognitive disorders. In this session, we will review novel neurostimulation modalities including transcranial direct current stimulation (tDCS), deep transcranial magnetic stimulation (dTMS), and photobiomodulation and their application to treatment of NPS in MCI and AD. Preliminary findings will be reviewed from ongoing clinical trials of neurostimulation for NPS in neurocognitive disorders: 1) Transcranial direct current stimulation (tDCS) combined with exercise for treatment of apathy in AD (Dr. Krista Lanctôt); 2) TDCS for treatment of agitation in AD (Dr. Sanjeev Kumar); 3) Deep transcranial magnetic stimulation (dTMS) for depression in MCI or AD [ClinicalTrials.gov Identifier: NCT03665831] (Dr. Linda Mah); 4) Photobiomodulation therapy for AD and as a potential treatment for NPS in neurocognitive disorders (Dr. Corinne Fischer).

Agitated Psychiatric Patient.

This scenario was developed to educate emergency medicine residents about the diagnosis and management of the agitated psychiatric patient. The prevalence of agitation among patients in the emergency department is increasing, with an estimated 1.7 million events occurring annually in the United States.1 There are various methodologies for de-escalation, including verbal and chemical de-escalation and physical restraints. Chemical and/or physical restraints are sometimes necessary to ensure patient and staff safety when verbal de-escalation is ineffective, particularly since agitation is the leading cause of hospital staff injuries.2 Chemical restraints have been shown to be less physically traumatizing to patients.3 4 Adverse events associated with physical restraints include persistent psychological distress, blunt chest trauma, aspiration, respiratory depression, and asphyxiation leading to cardiac arrest.5 In regards to chemical restraints, adverse event reporting has been heterogeneous among studies, but the most consistent reported events involve respiratory compromise such as desaturation, airway obstruction, and respiratory depression.3 A study measuring QTc (corrected QT interval) after high-dose intramuscular ziprasidone or haloperidol did not demonstrate any QTc longer than 480 msec.6 Other events linked to chemical restraints include uncommon cardiovascular events and extrapyramidal side effects from medications.3 The main classes of medications utilized for chemical restraint include first-generation antipsychotics (eg, haloperidol and droperidol), second-generation antipsychotics (olanzapine, quetiapine, risperidone, aripiprazole, and ziprasidone), benzodiazipenes (eg, lorazepam and midazolam), and N-methyl-D-aspartic acid (NMDA) receptor antagonists (eg, ketamine).7,8 It is important to exclude other medical causes of agitation, consider the differential diagnoses, and then select a medication that is tailored to address underlying etiologies while remaining cognizant of the side effect profiles of these chemical agents.Educational Objectives: At the conclusion of the simulation session, learners will be able to: 1) Obtain a relevant focused history and physical examination on the agitated psychiatric patient. 2) Develop a differential for the agitated psychiatric patient, including primary psychiatric conditions and other organic pathologies. 3) Discuss the management of the agitated psychiatric patient, including the different options available for chemical sedation. 4) Prioritize safety of self and staff when caring for an agitated psychiatric patient. This session was conducted using simulation with a standardized patient, followed by a debriefing session and lecture on the presentation, differential diagnosis, and management of the agitated psychiatric patient. Debriefing methods may be left to the discretion of participants, but the authors have utilized advocacy-inquiry techniques. This scenario may also be run as an oral board examination case. The residents are provided a survey at the completion of the debriefing session to rate different aspects of the simulation, as well as provide qualitative feedback on the scenario. This survey is specific to the local institution's simulation center. Feedback from the residents was overwhelmingly positive, although many stated that they felt some degree of intimidation or stress from the standardized patient who did not break from their role throughout the scenario.The local institution's simulation center feedback form is based on the Center of Medical Simulation's Debriefing Assessment for Simulation in Healthcare (DASH) Student Version Short Form9 with the inclusion of required qualitative feedback if an element was scored less than a 6 or 7. This session received mostly 7 scores (extremely effective/outstanding). This is a physically safe method for reviewing management of the agitated psychiatric patient. There are multiple potential presentations of the agitated psychiatric patient, as well as varying underlying etiologies. These scenarios may be tailored to the needs of the learner, including identifying agitation, pharmacologic review, and de-escalation techniques.

Psychopharmacology in dermatology: Treatment of primary psychiatric conditions in dermatology.

The role of psychotropic drugs in psychodermatology is still debatable, due to the quality of the evidence that supports it. There are several case reports and open trials with variable results. There is an additional difficulty in finding therapists trained in effective psychotherapy techniques, justify the need for more research on the available pharmacological options. The present review emphasizes pharmacological treatment in psychodermatology, specifically in cases of primary psychiatric disorders that are expressed with self-inflicted cutaneous signs and symptoms, in which drugs can play a central role in ameliorating symptoms or be useful in combination with psychotherapeutic approach of these disorders.

A combination of total tau and neurofilaments discriminates between neurodegenerative and primary psychiatric disorders.

Neuropsychiatric symptoms are commonly observed in neurodegenerative diseases. No biomarker is currently available to diagnose psychiatric conditions. As a consequence, the distinction between psychiatric and neurodegenerative disorders can be challenging in daily practice. This retrospective study included a cohort of 64 primary psychiatric patients (PSY) and 162 patients suffering from various neurodegenerative disorders (NDG). Total tau (t-Tau), phosphorylated tau (p-Tau), Aβ1-42 peptide (Aβ1-42) and neurofilament light chain protein (NfL) were analysed in cerebrospinal fluid. The discrimination between PSY and NDG patients was assessed using both individual and combined analysis of cerebrospinal fluid markers. Cerebrospinal fluid t-Tau and NfL exhibited the best diagnostic performances: they were able to discriminate between PSY and each subgroup of NDG patients. t-Tau had the highest sensitivity (93.8%) but a poor specificity (67.3%). Indeed, some NDG subgroups exhibited low t-Tau levels comparable to PSY patients. A sequential combination t-Tau + NfL improved the characterization of patients, especially in these particular subgroups, increasing specificity up to 89.6% without modification of sensitivity. Finally, this combination of markers led to a high classification rate of 90.7% for the whole cohort of patients. The sequential combination t-Tau+NfL enables the biological detection of neurodegeneration in patients with psychiatric features. This association of markers seems to be a promising strategy for a differential diagnosis in clinical practice between primary psychiatric conditions and neurodegenerative disorders, thus improving medical care of patients.
