Social distancing to limit COVID-19 transmission has led to extensive lifestyle changes, including for people with dementia (PWD). The aim of this study, therefore, was to assess the impact of lockdown on the mental health of PWD and their carers.

Dementia with Lewy bodies (DLB) is the second most common neurodegenerative cause of dementia, behind Alzheimer's disease (AD). The profile of inflammation in AD has been extensively researched in recent years, with evidence that chronic peripheral inflammation in midlife increases the risk of late-onset AD, and data supporting inflammation being associated with disease progression. In contrast, our understanding of the role of inflammation in DLB is less developed. Most research to date has examined inflammation in related disorders, such as Parkinson's disease, but there is now a growing range of literature examining inflammation in DLB itself. We present a review of the literature in this field, exploring a range of research methodologies including those quantifying markers of inflammation in cerebrospinal fluid, peripheral blood, post-mortem brain tissue, and using neuroimaging and preclinical data. Our review reveals evidence from PET imaging and peripheral blood analysis to support an increase in cerebral and peripheral inflammation in mild or prodromal DLB, that dissipates with disease progression. We present evidence from post-mortem brain tissue and pre-clinical studies that indicate α-synuclein directly promotes inflammation, but that also support the presence of AD co-pathology as an important factor in the profile of neuroinflammation in DLB. We propose that specific markers of inflammation may play a sentinel role in the mild stage of the disease, particularly when combined with AD pathology. We advocate further examination of the profile of inflammation in DLB through robust longitudinal studies, to enhance our understanding of the pathogenesis of the disease. The goal should be to utilise future results to develop a composite biomarker to aid diagnosis of DLB, and to potentially identify novel therapeutic targets.

A treatment escalation plan (TEP) enables timely and appropriate decision making in the management of deteriorating patients. The COVID-19 pandemic precipitated the widespread use of TEPs in acute care settings throughout the National Health Service (NHS) to facilitate safe and effective decision making. TEP proformas have not been developed for the inpatient psychiatric setting. This is particularly concerning in old age psychiatry inpatient wards where patients often have multiple compounding comorbidities and complex decisions regarding capacity are often made. Our aim for this quality improvement project was to pilot a novel TEP proforma within a UK old age psychiatry inpatient hospital. We first adapted a TEP proforma used in our partner acute tertiary hospital and implemented it on our old age psychiatry wards. We then further refined the form and gathered data about uptake, length of time to complete a TEP and the ceiling of care documented in the TEP. We also explored staff, patient and family views on the usefulness of TEP proformas using questionaries. TEP decisions were documented in 54% of patient records at baseline. Following revision and implementation of a TEP proforma this increased to 100% on our two wards. The mean time taken to complete a TEP was reduced from 7.1 days to 3.2 days following inclusion of the TEP proforma in admission packs. Feedback from staff showed improvements in understanding about TEP and improved knowledge of where these decisions were documented. We advocate the use of TEP proformas on all old age psychiatry inpatient wards to offer clear guidance to relatives and treating clinicians about the ceilings of care for patients. There are potentially wider benefits to healthcare systems by reducing inappropriate transfers between psychiatry and acute NHS hospitals.

Catatonia is a clinical syndrome characterized by psychomotor disruption, which often goes undiagnosed. Most reports have focused on interventions and outcomes for catatonia in younger people and those with schizophrenia. The clinical characteristics and course of catatonia in old age are poorly understood. We present a report of an older person whose catatonia was refractory to extensive treatment, and we identify important implications for the management of catatonia in old age.

People with dementia (PWD) are vulnerable to abrupt changes to daily routines. The lockdown enforced on the 23rd of March 2020 in the UK to contain the expansion of the COVID-19 pandemic limited opportunities for PWD to access healthcare services and socialise. The SOLITUDE study explored the potential long-term effects of lockdown on PWD's symptoms and carers' burden.
