Absent sleep EEG spindle activity in GluA1 (Gria1) knockout mice: relevance to neuropsychiatric disorders
(2018-08)Sleep EEG spindles have been implicated in attention, sensory processing, synaptic plasticity and memory consolidation. In humans, deficits in sleep spindles have been reported in a wide range of neurological and psychiatric ... -
Bidirectional associations between COVID-19 and psychiatric disorder: retrospective cohort studies of 62 354 COVID-19 cases in the USA
(2020)Background Adverse mental health consequences of COVID-19, including anxiety and depression, have been widely predicted but not yet accurately measured. There are a range of physical health risk factors for COVID-19, but ... -
Cerebral venous thrombosis: a retrospective cohort study of 513,284 confirmed COVID-19 cases and a comparison with 489,871 people receiving a COVID-19 mRNA vaccine
(2021-04)Objectives To estimate the absolute risk of cerebral venous thrombosis (CVT) and portal vein thrombosis (PVT) in the two weeks following a diagnosis of COVID-19, and to assess the relative risks (RR) compared to influenza ... -
Cognitive Behavioural Therapy for Nightmares for Patients with Persecutory Delusions (Nites): An Assessor-Blind, Pilot Randomized Controlled Trial
(2019-05)Objective:Nightmares are relatively common in patients experiencing psychosis but rarely assessed or treated. Nightmares may maintain persecutory delusions by portraying fears in sensory-rich detail. We tested the potential ... -
Dopaminergic modulation of regional cerebral blood flow: An arterial spin labelling study of genetic and pharmacological manipulation of COMT activity
(2021-07)Dopamine has direct and complex vasoactive effects on cerebral circulation. Catechol-O-methyltransferase (COMT) regulates cortical dopamine, and its activity can be influenced both genetically and pharmacologically. COMT ... -
Ethical Issues in Consent for the Re-use of Data in Health Data Platforms
(2020-12)Data platforms represent a new paradigm for carrying out health research. In the platform model, datasets are pooled for remote access and analysis, so novel insights for developing better stratified and / or personalised ... -
Genetics of self-reported risk-taking behaviour, trans-ethnic consistency and relevance to brain gene expression
(2018)Risk-taking behaviour is an important component of several psychiatric disorders, including attention-deficit hyperactivity disorder, schizophrenia and bipolar disorder. Previously, two genetic loci have been associated ... -
The genomic basis of mood instability: identification of 46 loci in 363,705 UK Biobank participants, genetic correlation with psychiatric disorders, and association with gene expression and function
(2019)Genome-wide association studies (GWAS) of psychiatric phenotypes have tended to focus on categorical diagnoses, but to understand the biology of mental illness it may be more useful to study traits which cut across traditional ... -
Incidence and outcomes of eating disorders during the COVID-19 pandemic
(2021-07)There are concerns that eating disorders have become commoner during the coronavirus disease 2019 (COVID-19) pandemic. Using the electronic health records of 5.2 million people aged under 30, mostly in the USA, we show ... -
Incidence of neurodegenerative and cerebrovascular diseases associated with antihypertensive drug classes
(2021-01)Antihypertensive drugs (AHTs) are associated with lowered risks of neurodegenerative diseases and stroke. However, the relative risks associated with different AHT classes are unclear. Using an electronic health record ... -
Incidence of Parkinson’s disease, dementia, cerebrovascular disease and stroke in bipolar disorder compared to other psychiatric disorders: An electronic health records network study of 66 million people
(2020-10)Bipolar disorder has been associated with an increased risk for neurodegenerative diseases, but uncertainties remain. The risk relative to other psychiatric disorders is not established. Methods We used a federated ... -
Induced pluripotent stem cells in psychiatry: a critical review
(2021-01)A key challenge in psychiatry research is the development of high-fidelity model systems that can be experimentally manipulated to explore and test pathophysiological mechanisms of illness. In this respect, the emerging ... -
Onset and recurrence of psychiatric disorders associated with anti-hypertensive drug classes
(2021-05)The major anti-hypertensive (AHT) drug classes have been associated with differential risks of psychiatric disorders. However, existing data are limited largely to depression, and confounding variables have not always been ... -
Patient fibroblast circadian rhythms predict lithium sensitivity in bipolar disorder
(2020-05)Bipolar disorder is a chronic neuropsychiatric condition associated with mood instability, where patients present significant sleep and circadian rhythm abnormalities. Currently, the pathophysiology of bipolar disorder ... -
The psychopathology of NMDAR-antibody encephalitis in adults: a systematic review and phenotypic analysis of individual patient data
(2019-03)Early immunotherapy administration improves outcomes in patients with N-methyl-D-aspartate receptor (NMDAR)-antibody encephalitis. As most patients with NMDAR-antibody encephalitis present to psychiatrists, the psychopathology ... -
Six-month Neurological and Psychiatric Outcomes in 236,379 Survivors of COVID-19
(2021-01)Background. Neurological and psychiatric sequelae of COVID-19 have been reported, but there are limited data on incidence rates and relative risks. Methods. Using retrospective cohort studies and time-to-event analysis, ... -
Sleep disturbance and psychiatric disorders
(2020-07)Signs of mental ill health that cut across psychiatric diagnostic categories at high rates are typically viewed as non-specific occurrences, downgraded in importance and disregarded. However, problems not associated with ... -
A Structural Brain Network of Genetic Vulnerability to Psychiatric Illness
(2020-05)Psychiatry is undergoing a paradigm shift from the acceptance of distinct diagnoses to a representation of psychiatric illness that crosses diagnostic boundaries. How this transition is supported by a shared neurobiology ... -
Voltage-gated calcium channel blockers for psychiatric disorders: genomic reappraisal
(2019-06)We reappraise the psychiatric potential of calcium channel blockers (CCBs). First, voltage-gated calcium channels are risk genes for several disorders. Second, use of CCBs is associated with altered psychiatric risks and ... -
Which Dopamine Polymorphisms are Functional? Systematic Review and Meta-Analysis of COMT, DAT, DBH, DDC, DRD1-5, MAOA, MAOB, TH, VMAT1 and VMAT2
(2019-05)BACKGROUND: Many polymorphisms in dopamine genes are reported to affect cognitive, imaging or clinical phenotypes. It is often inferred or assumed that such associations are causal, mediated by a direct effect of the ...
