A 76-year-old man complained about progressive dull feelings and weakness of the distal lower limbs that gradually progressed over a couple of months to the proximal legs and the hands. In addition, there was minor myalgia in the proximal muscles. He had had a myocardial infarction with cardiac arrhythmia three years earlier. He was treated with amiodarone afterwards. He did not have visual complaints and was otherwise healthy. He did not drink alcohol or use other drugs. He had not been treated with cytostatic drugs.
Race/ethnicity and sleep disturbances are associated with dementia risk.
Aims
To explore racial–ethnic disparities in sleep disturbances, and whether race/ethnicity moderates the relationship between sleep disturbances and dementia risk among older adults.
Method
We analysed ten annual waves (2011–2020) of prospective cohort data from the National Health and Aging Trends Study, a nationally representative USA sample of 6284 non-Hispanic White (n = 4394), non-Hispanic Black (n = 1311), Hispanic (n = 342) and non-Hispanic Asian (n = 108) community-dwelling older adults. Sleep disturbances were converted into three longitudinal measures: (a) sleep-initiation difficulty (trouble falling asleep within 30 min), (b) sleep-maintenance difficulty (trouble falling asleep after waking up early) and (c) sleep medication usage (taking medication to sleep). Cox proportional hazards models analysed time to dementia, after applying sampling weights and adjusting for sociodemographic characteristics and health.
Results
Black, Hispanic and Asian respondents exhibited higher frequencies of sleep-initiation and sleep-maintenance difficulties, but had less sleep medication usage, compared with White older adults. Among Hispanic respondents, sleep-initiation difficulty was associated with significantly decreased dementia risk (adjusted hazard ratio (aHR) = 0.34, 95% CI 0.15–0.76), but sleep-maintenance difficulty was associated with increased dementia risk (aHR = 2.68, 95% CI 1.17–6.13), compared with White respondents. Asian respondents using sleep medications had a significantly higher dementia risk (aHR = 3.85, 95% CI 1.64–9.04). There were no significant interactions for Black respondents.
Conclusions
Sleep disturbances are more frequent among older Black, Hispanic and Asian adults, and should be considered when addressing dementia disparities. Research is needed to explore how certain sleep disturbances may elevate dementia risk across different racial and ethnic subgroups.
An introduction and overview of intellectual disability. The American Psychiatric Association (APA) diagnostic criteria for intellectual disability (DSM-5 criteria) are covered: Deficits in general mental abilities; Impairment in adaptive functioning for individual’s age and sociocultural background which may include communication, social skills, person independence, and school or work functioning; All symptoms must have an onset during the developmental period; The condition may be subcategorised according to severity based on adaptive functioning as mild, moderate, or severe. The chapter also covers the role and evidence base for medication and key issues when prescribing for people with intellectual disability.
People with intellectual disability are more likely to experience mental health difficulties, and their treatment responses may differ from those in the general population. This book, written by leading clinical practitioners from around the world, provides comprehensive guidance on prescribing for people with intellectual disability, as well as general information on their clinical care. The guidelines have been conceived and developed by clinicians working in intellectual disability services. Combining the latest evidence and expert opinion, they provide a consensus approach to prescribing as part of a holistic package of care, and include numerous case examples and scenarios. Now in its fourth edition, this update reflects the changes in prescribing practice; it places emphasis on clinical scenarios and case examples and includes input from service users and their families. This is a practical guide for busy clinicians, and a valuable reference for all primary and secondary healthcare professionals.
This chapter reviews current options for pharmacological interventions for treating dementia and MCI. For the last 20 years, ACHe inhibitors have been the main option for symptomatic treatment of dementia. The evidence base for their effectiveness is considered. More recent developments are reviewed for pharmacological interventions intended to be disease-modifying. These aim to remove beta amyloid protein, which is the hallmark of Alzheimer’s disease, with the aim of halting the disease’s progress. This is an emerging field, with an evidence base which is still developing, but represents an exciting development.
To explore the views of general practitioners (GPs) and nurses on type 2 diabetes (T2D) management, including the use of recently funded T2D medications in New Zealand (NZ) and their perceived barriers to providing optimal care.
Background:
T2D is a significant health concern in NZ, particularly among Māori and Pacific adults. Characterised by prolonged hyperglycaemia, T2D is generally a progressive condition requiring long-term care.
Methods:
Semi-structured interviews were conducted between July and December 2022 with 21 primary care clinicians (10 GPs and 11 nurses/nurse prescribers) from nine different general practice clinics across the Auckland and Waikato regions of NZ. Framework analysis was conducted to identify common themes in clinicians’ perceptions and experiences with T2D management.
Findings:
Three themes were identified: health-system factors, new medications, and solution-based approaches. Lack of clinician time, healthcare funding, staff shortages, and burn-out were identified as barriers to T2D management under health-system factors. The two newly funded medications, empagliflozin and dulaglutide, were deemed to be a positive change for T2D care in that they improved patient satisfaction and clinical outcomes, but several clinicians were hesitant to prescribe these medications. Participants suggested that additional education and specialist diabetes support would be helpful to inform optimal medication prescribing and that better use of a multi-disciplinary team (clinical and support staff) could support T2D care by reducing workload, addressing cultural gaps in healthcare delivery, and reducing burnout. An improved primary care work environment, including appropriate professional development to support prescribing of new medications and the value of collaboration with a non-regulated workforce, may be required to facilitate optimal T2D management in primary care. Future research should focus on interventions to increase support for both clinical teams and patients while adopting a culturally appropriate approach to increase patient satisfaction and improve health outcomes.
To quantify the proportion of referrals sent to Crumlin Cardiology Department for cardiac screening prior to commencement or modifying attention deficit hyperactivity disorder medication and assess the number detected with a clinically significant abnormality.
Methods:
A prospective audit was performed over a 6-month period, from November 2021 to April 2022 inclusive. Referrals sent via outpatient department triage letters, electrocardiogram dept. email, and walk-in electrocardiogram service were screened for those pertaining to commencing or modifying medication for children with attention deficit hyperactivity disorder. Each referral was coded against National Institute for Health and Care Excellence guidelines to determine the degree of clinical details given. Reported abnormalities, recommended management, and correspondence were recorded.
Results:
Ninety-one referrals were received during the 6-month audit period. More than half lacked a clinical indication for referral (53/91, 58.2%), with fewer than one third (26/91, 28.5%) meeting National Institute for Health and Care Excellence criteria for referral for cardiology. Eighty (80/91) referrals had clinical outcomes available for review (missing outpatient department information and age outside of service range accounted for eleven referrals with unavailable clinical outcomes). Of the eighty clinically reviewed referrals, seventy-two (72/80, 90%) were reported as normal with no cardiology follow up required. Eight referrals (8/80, 10%) were reviewed in the Cardiology Outpatient Department prior to commencement or modifying attention deficit hyperactivity disorder medication. Of these, only one (1/80 1%) had a clinically significant abnormality which was a potential contraindication to attention deficit hyperactivity disorder medication use, and this referral was appropriate as per National Institute for Health and Care Excellence guidelines.
Conclusion:
Routine screening prior to attention deficit hyperactivity disorder medication prescription in the absence of clinical indications (as per National Institute for Health and Care Excellence) contributed to delays in medication initiation among young people with attention deficit hyperactivity disorder. Unnecessary referrals have resource implications for cardiology clinical team. Improved adherence to National Institute for Health and Care Excellence guidelines would provide benefits for patients and clinicians.
Coinciding with the 75th anniversary of John Cade's seminal publication that first reported lithium's antimanic efficacy, we briefly recount the salient findings of the historic paper and draw attention to the important psychiatric research in Britain that reinforced its findings and the critical British opinions that likely impeded its clinical use.

Bipolar depression is an important and difficult to treat facet of bipolar disorder. However, it poses a number of challenges to the clinician. This chapter offers an overview of the difficulties in diagnosing bipolar depression and the main risks associated with it, whilst emphasising the factors which differentiate it from unipolar depression. Following this, there is an overview of the official guidance and evidence base for treatment options. There is an especial focus on pharmacotherapy, but the chapter also reviews psychotherapy, ECT, as well as emerging treatment options, such as sleep interventions and ketamine.
Changing practice patterns caused by the pandemic have created an urgent need for guidance in prescribing stimulants using telepsychiatry for attention-deficit hyperactivity disorder (ADHD). A notable spike in the prescribing of stimulants accompanied the suspension of the Ryan Haight Act, allowing the prescribing of stimulants without a face-to-face meeting. Competing forces both for and against prescribing ADHD stimulants by telepsychiatry have emerged, requiring guidelines to balance these factors. On the one hand, factors weighing in favor of increasing the availability of treatment for ADHD via telepsychiatry include enhanced access to care, reduction in the large number of untreated cases, and prevention of the known adverse outcomes of untreated ADHD. On the other hand, factors in favor of limiting telepsychiatry for ADHD include mitigating the possibility of exploiting telepsychiatry for profit or for misuse, abuse, and diversion of stimulants. This Expert Consensus Group has developed numerous specific guidelines and advocates for some flexibility in allowing telepsychiatry evaluations and treatment without an in-person evaluation to continue. These guidelines also recognize the need to give greater scrutiny to certain subpopulations, such as young adults without a prior diagnosis or treatment of ADHD who request immediate-release stimulants, which should increase the suspicion of possible medication diversion, misuse, or abuse. In such cases, nonstimulants, controlled-release stimulants, or psychosocial interventions should be prioritized. We encourage the use of outside informants to support the history, the use of rating scales, and having access to a hybrid model of both in-person and remote treatment.

This chapter gives an overview and update on functional neurological disorder (FND), also known as dissociative neurological symptom disorder and previously known as conversion disorder. FND is the presence of neurological symptoms that are not explained or explainable by a neurological disorder. FND has been assumed to be a purely stress-related psychiatric disorder, but over the recent decades, this simplistic conception has been supplanted by more nuanced models of symptom generation. FND is no longer a diagnosis of exclusion. Instead, wherever possible, it is ruled-in by distinct features of history and examination, the latter known as positive clinical signs. There have been concurrent advances in the biological understanding of FND, exemplified by functional neuroimaging studies that have indicated that FND can be distinguished from, for example, feigned symptoms mimicking the disorder. FND encompasses multiple subtypes, from seizures to motor disorders to sensory abnormalities. Symptoms often co-occur, sometimes in a striking fashion.
Current treatment options for FND are limited, and many patients have severe long-term symptoms despite best-available treatment including psychological therapies and medication. Nevertheless, there are simple, and sometimes effective, steps that clinicians can take to manage and treat patients.
Dentists require a comprehensive understanding of drugs used in clinical practice in order to safely prescribe and manage medication use in their patients. Handbook of Dental Therapeutics provides practical coverage of drugs in dentistry. This text draws together the latest recommendations for Australia and Aotearoa New Zealand, covering common drugs dentists administer and prescribe, perioperative management considerations, oral adverse effects and drug safety. Dedicated chapters on how therapeutics affect children, pregnant and breastfeeding women, and elderly patients enable readers to prescribe and administer medications across the lifespan. Concisely written, the text is a practical guide which includes dosage recommendations and practice points. Diagrams, graphs and tables summarise complex information to ensure readers have readily accessible information on the drugs most commonly used in dentistry. Handbook of Dental Therapeutics is an essential text that equips dental students and dentists with succinct, clinically relevant information about all aspects of drugs in dentistry.
This study aimed to develop an efficient data collection and curation process for all drugs and natural health products (NHPs) used by participants to the Canadian Longitudinal Study on Aging (CLSA). The three-step sequential process consisted of (a) mapping drug inputs collected through the CLSA to the Health Canada Drug Product Database (DPD), (b) algorithm recoding of unmapped drug and NHP inputs, and (c) manual recoding of unmapped drug and NHP inputs. Among the 30,097 CLSA comprehensive cohort participants, 26,000 (86.4%) were using a drug or an NHP with a mean of 5.3 (SD 3.8) inputs per participant user for a total of 137,366 inputs. Of those inputs, 70,177 (51.1%) were mapped to the Health Canada DPD, 20,729 (15.1%) were recoded by algorithms, and 44,108 (32.1%) were manually recoded. The Direct algorithm correctly classified 99.4 per cent of drug inputs and 99.5 per cent of NHP inputs. We developed an efficient three-step process for drug and NHP data collection and curation for use in a longitudinal cohort.
The dichotomies of ‘typical/atypical’ or ‘first/second generation’ have been employed for several decades to classify antipsychotics, but justification for their use is not clear. In the current analysis we argue that this classification is flawed from both clinical and pharmacological perspectives. We then consider what approach should ideally be employed in both clinical and research settings.
Adverse effects are a common concern when prescribing and reviewing medication, particularly in vulnerable adults such as older people and those with intellectual disability. This paper describes the development of an app giving information on side-effects, called Medichec, and provides a description of the processes involved in its development and how drugs were rated for each side-effect. Medications with central anticholinergic action, dizziness, drowsiness, hyponatraemia, QTc prolongation, bleeding and constipation were identified using the British National Formulary (BNF) and frequency of occurrence of these effects was determined using the BNF, product information and electronic searches, including PubMed.
Results
Medications were rated using a traffic light system according to how commonly the adverse effect was known to occur or the severity of the effect.
Clinical implications
Medichec can facilitate access to side-effects information for multiple medications, aid clinical decision-making, optimise treatment and improve patient safety in vulnerable adults.
Autonomic nervous system (ANS) dysregulation might be relevant to the pathophysiology of fatigue and cognitive impairment in depression and perhaps should be considered when making prescribing decisions.
Aims
To determine the relationship of self-reported ANS symptoms with fatigue, cognition and prescribed medication in people with a diagnosis of depression, in comparators without depression but with other mental health, neurodevelopmental or neurodegenerative disorders (active controls) and in healthy controls.
Method
Cross-sectional analysis of an opportunistic sample from England. Self-reported data were collected on demographics, diagnosis, medication, ANS symptoms (Composite Autonomic Symptom Scale-31, COMPASS-31) and fatigue (Visual Analogue Scale for Fatigue, VAS-F). A subsample completed cognitive tests (THINC-it), including the subjective Perceived Deficits Questionnaire five-item version (PDQ-5). Spearman's correlation and mediation models were used to explore the relationship between COMPASS-31, VAS-F and PDQ-5 scores.
Results
Data were obtained for 3345 participants, 22% with depression. The depression group had significantly (P < 0.01) more severe autonomic dysregulation as measured by COMPASS-31 scores (median 30) than active (median 23) and healthy controls (median 10). The depression group had significantly higher symptom severity (P < 0.01) than both control groups on the VAS-F and PDQ-5. Overall, there was a significantly positive correlation (P < 0.01) between COMPASS-31, VAS-F scores (Spearman's rho rs = 0.44) and PDQ-5 scores (rs = 0.56). COMPASS-31 scores mediated greater symptom severity on the VAS-F and PDQ-5 for those with depression. COMPASS-31 scores remained significantly different between the depression group and both control groups independently of medication.
Conclusions
People with a diagnosis of depression report worse fatigue and cognition than active and healthy comparators; this appears to be mediated by ANS dysregulation.

Violence from older adults is a challenge for healthcare services. Risk factors include those common to working-age adults, namely substance misuse, active psychotic symptoms and inadequate care, and those more typical in older age, including cognitive impairment, acute confusion and pain. Aggression is a barrier to good care and a challenge to manage in older adults who are more vulnerable to medication effects and side effects. Medications must be used with caution. Prevention of violence through sensitive person-centred care and management of risk factors is recommended, as is non-pharmacological management. Here, we review management through non-pharmacological and pharmacological measures.

This chapter considers the use of medication as an emergency response in the management of violent and disturbed behaviour. It addresses the complex factors surrounding the decision to use rapid tranquillisation, followed by reviewing the risks and benefits of specific medication options. This is discussed within the context and continuum of acute patient care, in keeping with good practice principles, and with consideration to the relevant patient-related and medication-related risks. The current evidence for using medication or ECT in the management of a medium- and longer-term risk of violence in the context of mental illness is briefly reviewed. The recommendations are applicable to all inpatient mental health units in the United Kingdom.
Recent systematic reviews and meta-analyses conclude that similar social cognitive impairments are found in autism spectrum disorder (ASD) and schizophrenia spectrum disorder (SSD). While methodological issues have been mentioned as a limitation, no study has yet explored the magnitude of methodological heterogeneity across these studies and its potential impact for their conclusion. The purpose of this study was to systematically review studies comparing social cognitive impairments in ASD and SSD with a focus on methodology. Following the PRISMA guidelines, we searched all publications on PubMed, PsycINFO, and Embase. Of the 765 studies identified in our data base searches, 21 cross-sectional studies were included in the review. We found significant methodological heterogeneity across the studies. In the 21 studies, a total of 37 different measures of social cognition were used, 25 of which were only used in 1 study. Across studies, the same measure was often said to be assessing different constructs of social cognition – a confusion that seems to reflect the ambiguous definitions of what these measures test in the studies that introduced them. Moreover, inadequate differential diagnostic assessment of ASD samples was found in 81% of the studies, and sample characteristics were markedly varied. The ASD and SSD groups were also often unmatched in terms of medication usage and substance use disorder history. Future studies must address these methodological issues before a definite conclusion can be drawn about the potential similarity of social cognitive impairments in ASD and SSD.
Psychological and pharmacological therapies are the recommended first-line treatments for common mental disorders (CMDs) but may not be universally accessible or utilised.
Aims
To determine the extent to which primary care patients with CMDs receive treatment and the impact of sociodemographic, work-related and clinical factors on treatment receipt.
Method
National registers were used to identify all Stockholm County residents aged 19–64 years who had received at least one CMD diagnosis (depression, anxiety, stress-related) in primary care between 2014 and 2018. Individuals were followed from the date of their first observed CMD diagnosis until the end of 2019 to determine treatment receipt. Associations between patient factors and treatment group were examined using multinomial logistic regression.
Results
Among 223 271 individuals with CMDs, 30.6% received pharmacotherapy only, 16.5% received psychological therapy only, 43.1% received both and 9.8% had no treatment. The odds of receiving any treatment were lower among males (odds ratio (OR) range = 0.76 to 0.92, 95% CI[minimum, maximum] 0.74 to 0.95), individuals born outside of Sweden (OR range = 0.67 to 0.93, 95% CI[minimum, maximum] 0.65 to 0.99) and those with stress-related disorders only (OR range = 0.21 to 0.51, 95% CI[minimum, maximum] 0.20 to 0.53). Among the patient factors examined, CMD diagnostic group, prior treatment in secondary psychiatric care and age made the largest contributions to the model (R2 difference: 16.05%, 1.72% and 1.61%, respectively).
Conclusions
Although over 90% of primary care patients with CMDs received pharmacological and/or psychological therapy, specific patient groups were less likely to receive treatment.
