Autism spectrum disorder (ASD) is defined by the American Psychiatric Association as persistent deficits in social communication and interactions and restricted, repetitive patterns of behavior, interests, or activities. There are many potential etiological causes for ASD. In the United States, the combined prevalence of ASD per 1,000 children was 23 in 2018. The American Academy of Pediatrics (AAP) recommends screening specifically for ASD during regular doctor visits at 18 and 24 months to ensure systematic monitoring for early signs of ASD. Most reported concerns from parents relate to abnormal childhood developmental trajectory and history of unusual behaviors, with variability in ages when features suggestive of ASD are most noticeable. Behavioral interventions for ASD focus on minimizing the effects of developmental delays and maximizing speech/language, motor, social-emotional, and cognitive skills. Medications can be used to target comorbid conditions or problematic behaviors that interfere with progress or pose safety concerns. The financial burden on families of children with ASD is correlated with the existing societal financial safety net. Poorer outcomes are expected when the family carries a substantial share of the cost to support the development of children with ASD, especially in lower-income households.
The diagnostic process is a crucial aspect of medical practice. Psychiatric diagnosis involves information gathering, mental state assessment, hypothesis integration with laboratory or imaging when needed, and data interpretation. Clinical reasoning operates through two systems: System 1, characterized by intuitive pattern recognition; and System 2, which employs meticulous critical thinking. These systems complement each other, with System 1 being faster but riskier while System 2 offers a more planned approach. Today, the Diagnostic and Statistical Manual of Mental Disorders (DSM) and the International Classification of Diseases (ICD) are the two primary diagnostic manuals. Despite their imperfections and reliance on symptom descriptions, the DSM and ICD remain indispensable tools in psychiatry for communication, research, and clinical decision-making.
Bipolar disorder (BD) is one of the most important and potentially incapacitating mental disorders, typically characterized by the alternation of depressive symptoms with periods of elevated mood, called manic or hypomanic episodes. The present chapter provides an overview of the main aspect of this psychiatric condition, including its clinical presentation, diagnosis, pathophysiology, and therapeutic aspects. While the diagnosis and management of BD can be challenging, ongoing research has led to considerable advances in its understanding. It is expected that those advances will bring about improvements in the identification and treatment of this mental illness.
Early encounters with patients provide a valuable opportunity to understand their presenting complaints and needs. In order to do this effectively, it is important to have a structured approach to evaluating their symptoms. Using a step-by-step approach, this chapter instructs you how to understand a patient’s initial presenting complaints and assess their needs in an initial assessment. This includes setting the scene with the patient, evaluating their insomnia using a structured sleep interview, and using observation to obtain helpful and pertinent clinical information in collaboration with your patient.
this chapter reads Romeo and Juliet in the context of early modern medical communities in which people of all social groups worked together, for better or ill, to diagnose the diseases of the young. It reads the play’s interest in plants and medicines, in the illnesses of childrne (especially greensickness) and argues that narrative structure of Romeo and Juliet enacts for the audience similar communal diagnostic processes as those used outside the theatre.
Based on Dr Colin Espie's 45 years of clinical and research experience, this expert manual for clinicians and healthcare professionals shows how best to assess insomnia and deliver effective treatment in everyday practice using cognitive and behavioural therapeutics (CBTx). The book provides in-depth background on the importance of sleep, the interactions between sleep and health, what insomnia is, and insomnia's negative impact on patients. Using detailed examples, metaphors, and practical guidance, it provides clear instructions on the evaluation of sleep complaints and on the why and how of selecting and providing a specific CBTx to suit the presenting patient. Delving beyond treating patients at the individual level, the book also considers how to develop an effective and efficient insomnia service at population scale.
Echinococcosis lacks sensitive serological diagnostic tools. The echinococcosis-specific antigens Eg95, AgB8/1 and the Em18 gene sequences were fused and expressed as the novel recombinant antigens rAgB8/1-Em18-Eg95 (T3) and rEm18-Eg95 (T2), used for the diagnosis of hydatid disease, prepared into an enzyme-linked immunosorbent reaction (ELISA) kit, and evaluated for their serological diagnostic value. The relative molecular weight of the T3 protein was 88.1 kDa, the purified concentration was 1.5 mg mL−1, and the purity was 80%. The relative molecular weight of T2 protein was 79.9 kDa, the total protein concentration was 0.5 mg mL−1, and the purity was less than 50%. The overall coincidence rate of T2 protein was low, and it was impossible to distinguish between negative and positive sera. The T3 antigen was coated at 1.0 μg mL−1, the cutoff value was 0.5271, and the serum dilution ratio was 1:400. A T3 ELISA kits (96 tests) was constructed to detect the serum of 272 clinically and pathologically confirmed cases. The sensitivity of T3 was 93.8%, and the specificity was 83.3%. The parasite cross-reaction was 30%. Satisfactorily, the Pearson correlation coefficient between the T3 OD value and lesion diameter was 0.707, showing a strong correlation. T3 exhibits better antigenicity than T2, and the prepared T3 ELISA diagnostic kits reached the laboratory diagnostic level of a commercial kits. T3 can distinguish human cystic echinococcosis (CE) and alveolar echinococcosis (AE) more significantly and predict the diameter of lesions according to the OD value, which provides practical value for drug or surgical efficacy.
This chapter explores how differing expectations and experiences manifest in diagnostic interactions in the memory clinic. We do this by microanalysing communication in dementia diagnosis feedback meetings, focusing on instances of misalignment between doctors and the person living with dementia. We examine three videos from a dataset of 101 recordings from two areas in the UK, collected as part of the ShareD study. We present different interactional contexts where the person receiving a dementia diagnosis choose to align or misalign with the doctors’ interactional projects of diagnosis delivery, prescribing medication and recommending support. Examination of these instances suggests that misalignment between the assessment of symptoms may, at least in part, reflect interactional facework in the face of dementia as a challenge to self-identity.
Gender is a socially constructed concept influenced by social practices, norms, and expectations. The impact of gender differences on mental health has been long recognized, with consequences such as over-diagnosis and pathologization or under-diagnosis of some disorders depending on gender. This also has implications for the treatments that each gender receives. In this narrative review, we will analyze (a) the gender differences in the prevalence of mental disorders, (b) the explanations for gender differences in mental health, including biological, social constructionist, and sociocultural risk factors, and (c) the gender differences in the treatment of mental disorders, including differences in health-seeking behavior and treatment outcomes. Overall, there is a consistent pattern of differences in prevalence, with women more likely to have internalizing disorders (e.g., anxiety or depression) and men more likely to have externalizing disorders (e.g., antisocial personality or substance use). The explanations aimed at disentangling the reasons for these gender differences are complex, and several approaches should be considered to achieve a comprehensive explanation. In addition to biological factors (e.g., hormonal changes), social constructionist factors (e.g., biased diagnostic criteria and clinicians’ gender bias) and sociocultural factors (e.g., feminization of poverty, gender discrimination, violence against women, and prescriptive beauty standards) should be considered. Future studies in the field of mental health should consider gender differences and explore the bio-psycho-socio-cultural factors that may underlie these differences.
Difficulty falling asleep and/or maintaining sleep are common complaints in patients visiting medical clinics. Insomnia can occur alone or in combination with other medical or psychiatric disorders. Diagnosis and management of insomnia at times are perplexing. This updated study review aimed at a clinical algorithm for diagnosis and treatment of insomnia in adults. We developed an easy-to-apply algorithm to diagnose and manage insomnia that can be used by general practitioners and non-sleep specialists. To this end, our team reviewed the previous studies to determine the prevalence, evaluation, and treatment of insomnia. We used the results to develop a clinical algorithm for diagnosing and managing insomnia.
Insomnia occurs in a short (less than 3 months duration) or chronic form (≥3 months duration). Insomnia management includes both pharmacological and non-pharmacological interventions. There is ample research evidence for the impact of a variety of non-pharmacological treatments, but both types of treatments can be used for each patient. If there are any contradictions in the diagnosis process, therapists should use objective instruments, such as polysomnography, but they should not be in a hurry to use these instruments.
Schistosomiasis is a neglected tropical disease with significant health implications, particularly among children. A cross-sectional study was conducted among school-aged children (SAC) in Mwanga district, Tanzania, a region known to be co-endemic for S. haematobium and S. mansoni infection and where annual mass drug administration (MDA) has been conducted for 20 years. In total, 576 SAC from 5 schools provided a urine sample for the detection of Schistosoma circulating anodic antigen using the upconverting particle-based lateral flow (UCP-LF CAA) test. Additionally, the potential of the point-of-care circulating cathodic antigen (POC-CCA) and microhaematuria dipstick test as field-applicable diagnostic alternatives for schistosomiasis were assessed and the prevalence outcome compared to UCP-LF CAA. Risk factors associated with schistosomiasis was assessed based on UCP-LF CAA. The UCP-LF CAA test revealed an overall schistosomiasis prevalence of 20.3%, compared to 65.3% based on a combination of POC-CCA and microhaematuria dipstick. No agreement was observed between the combined POC tests and UCP-LF CAA. Factors associated with schistosomiasis included age (5–10 years), involvement in fishing, farming, swimming activities and attending 2 of the 5 primary schools. Our findings suggest a significant progress in infection control in Mwanga district due to annual MDA, although not enough to interrupt transmission. Accurate diagnostics play a crucial role in monitoring intervention measures to effectively combat schistosomiasis.
This chapter looks at Alzheimer’s disease, the most common cause of dementia. Incidence and prevalence figures are reviewed, along with an explanation of the two abnormal proteins involved in the development of the disorder, and the ‘amyloid cascade’ hypothesis. Cognitive assessment of Alzheimer’s disease is considered in terms of where this fits within the diagnostic process and diagnostic criteria. The bulk of the chapter focuses on the typical form of Alzheimer’s disease, and the chapter concludes with discussion of some atypical variants, such as posterior cortical atrophy (PCA), logopenic primary progressive aphasia (lvPPA), and frontal variant.
The process of diagnosing dementia and MCI is considered in depth in this chapter, drawing on criteria outlined in the DSM-V and ICD-11. This covers ways of assessing the two central components of a dementia diagnosis, namely the extent to which there has been a change in cognitive ability and whether there has been a change in everyday function. The contribution of neuropsychological assessment is explained, along with the use of cognitive screening measures. The difference between dementia and MCI is covered, along with how you differentiate between the two. There is also discussion of what background information to record, specifically in relation to factors which could affect cognitive function. The chapter finishes with a decision tree outlining the process involved in distinguishing between the two presentations. Having established whether dementia is present, how to determine the likely type of dementia is discussed in subsequent chapters.
Oral cancer survival rates have seen little improvement over the past few decades. This is mainly due to late detection and a lack of reliable markers to predict disease progression in oral potentially malignant disorders (OPMDs). There is a need for highly specific and sensitive screening tools to enable early detection of malignant transformation. Biochemical alterations to tissues occur as an early response to pathological processes; manifesting as modifications to molecular structure, concentration or conformation. Raman spectroscopy is a powerful analytical technique that can probe these biochemical changes and can be exploited for the generation of novel disease-specific biomarkers. Therefore, Raman spectroscopy has the potential as an adjunct tool that can assist in the early diagnosis of oral cancer and the detection of disease progression in OPMDs. This review describes the use of Raman spectroscopy for the diagnosis of oral cancer and OPMDs based on ex vivo and liquid biopsies as well as in vivo applications that show the potential of this powerful tool to progress from benchtop to chairside.
Around the world, people living in objectively difficult circumstances who experience symptoms of generalized anxiety disorder (GAD) do not qualify for a diagnosis because their worry is not ‘excessive’ relative to the context. We carried out the first large-scale, cross-national study to explore the implications of removing this excessiveness requirement.
Methods
Data come from the World Health Organization World Mental Health Survey Initiative. A total of 133 614 adults from 12 surveys in Low- or Middle-Income Countries (LMICs) and 16 surveys in High-Income Countries (HICs) were assessed with the Composite International Diagnostic Interview. Non-excessive worriers meeting all other DSM-5 criteria for GAD were compared to respondents meeting all criteria for GAD, and to respondents without GAD, on clinically-relevant correlates.
Results
Removing the excessiveness requirement increases the global lifetime prevalence of GAD from 2.6% to 4.0%, with larger increases in LMICs than HICs. Non-excessive and excessive GAD cases worry about many of the same things, although non-excessive cases worry more about health/welfare of loved ones, and less about personal or non-specific concerns, than excessive cases. Non-excessive cases closely resemble excessive cases in socio-demographic characteristics, family history of GAD, and risk of temporally secondary comorbidity and suicidality. Although non-excessive cases are less severe on average, they report impairment comparable to excessive cases and often seek treatment for GAD symptoms.
Conclusions
Individuals with non-excessive worry who meet all other DSM-5 criteria for GAD are clinically significant cases. Eliminating the excessiveness requirement would lead to a more defensible GAD diagnosis.
While previous studies have reported high rates of documented suicide attempts (SAs) in the U.S. Army, the extent to which soldiers make SAs that are not identified in the healthcare system is unknown. Understanding undetected suicidal behavior is important in broadening prevention and intervention efforts.
Methods
Representative survey of U.S. Regular Army enlisted soldiers (n = 24 475). Reported SAs during service were compared with SAs documented in administrative medical records. Logistic regression analyses examined sociodemographic characteristics differentiating soldiers with an undetected SA v. documented SA. Among those with an undetected SA, chi-square tests examined characteristics associated with receiving a mental health diagnosis (MH-Dx) prior to SA. Discrete-time survival analysis estimated risk of undetected SA by time in service.
Results
Prevalence of undetected SA (unweighted n = 259) was 1.3%. Annual incidence was 255.6 per 100 000 soldiers, suggesting one in three SAs are undetected. In multivariable analysis, rank ⩾E5 (OR = 3.1[95%CI 1.6–5.7]) was associated with increased odds of undetected v. documented SA. Females were more likely to have a MH-Dx prior to their undetected SA (Rao-Scott χ21 = 6.1, p = .01). Over one-fifth of undetected SAs resulted in at least moderate injury. Risk of undetected SA was greater during the first four years of service.
Conclusions
Findings suggest that substantially more soldiers make SAs than indicated by estimates based on documented attempts. A sizable minority of undetected SAs result in significant injury. Soldiers reporting an undetected SA tend to be higher ranking than those with documented SAs. Undetected SAs require additional approaches to identifying individuals at risk.
In this issue of BJPsych Advances Siddaway explores the challenges of assessing and treating post-traumatic stress disorder (PTSD) and complex PTSD. In this commentary I reflect on those challenges, not least of which is the need for a thorough understanding of different approaches to diagnoses. The very concept of diagnostic classification systems can be problematic, but when used sensitively they can aid communication, assessment and treatment. The relatively new diagnosis of complex PTSD may serve as a more accurate and more useful description of some psychological difficulties, leading to better treatment decisions. Good assessment, leading to accurate diagnosis, useful formulation and effective treatment takes time, and adequate resources should be allocated. Professionals can help patients to make well-informed choices about treatment options and they should offer evidence-based treatments without unnecessary delay.
Post-traumatic stress disorder (PTSD) is a complex, heterogeneous mental health problem that can be challenging to identify, assess, understand, diagnose and treat. This article provides an overview and critique of key topics, literature and principles to inform comprehensive and meticulous assessment of PTSDs. Although expert witnesses are the target audience, this article will have relevance for identifying, assessing, understanding and diagnosing PTSDs in all clinical contexts. A range of topics relevant to assessment are discussed, including: the complex relationship between trauma and PTSDs; DSM-5-TR PTSD and ICD-11 PTSD and complex PTSD diagnoses and the similarities and differences between them; the clinical presentation of PTSDs; psychological models of PTSDs; how to approach assessment and differential diagnosis; the impact of PTSD on neuropsychological abilities and functioning (disability); causation, reliability and assessing PTSDs when this is being considered as a legal defence; evidence-based interventions (medication, psychological therapy, when is the ‘right time’ for therapy, contraindications); and prognosis (if untreated, how long therapy/change takes). Given ongoing debate, the article proposes that trauma exposure is best defined in future iterations of the DSM and ICD as exposure to one or more psychologically threatening or horrific experiences that are overwhelming.
In the late 1970s, queer parents increasingly fought to maintain custody of their children from different-sex relationships. These mothers and fathers were responding in part to the gay liberation movement, which inspired them to come out and demand their rights. Also important was that the American Psychiatric Association declassified homosexuality as a mental illness, which eliminated what had been an all-but-impenetrable barrier to custody. Courts were nevertheless reluctant to grant these petitions, fearing that the children would learn to be gay or lesbian from the adults in their lives. In response to these court cases, social scientists developed research studies that concluded parental homosexuality had no effect on the future sexual orientation of children. Based on that work, family courts around the country granted custody to lesbian mothers and gay fathers in the late 1970s and early 1980s, creating the first wave of visible queer-headed families.
