Global Burden of Disease 2017 estimates for Major Depressive Disorder: a critical appraisal of the epidemiological evidence.

Objectives: To critically appraise the quality of the studies underpinning the Global Burden of Disease (GBD) 2017 estimates for Major Depressive Disorder (MDD) with respect to i) the GBD 2017 inclusion criteria and ii) population coverage. Design: Systematic critical appraisal. Setting: Not applicable. Participants: Not applicable. Main outcome measures: Each study was critically appraised with respect to the four GBD 2017 inclusion criteria: representativeness, study method and sample, diagnostic criteria and publication from 1980 onwards. Population coverage was calculated. Results: Less than half of studies (221/467, 47.3%) were nationally representative. Only 262/467 (56.1%) of studies reported specifically on MDD and more than a third did not use DSM or ICD diagnostic criteria: 94/467 (20.1%) did not specify any diagnostic criteria and 68/467 (14.6%) relied on self-reported depression for diagnosis. Only 62/467 (13.3%) of studies were conducted during the period 2011-2017. Only 107/195 (54.9%) of countries had one or more prevalence studies. Conclusions: GBD 2017 estimates for MDD are based on incomplete country and population coverage. The inclusion of studies with non-representative populations, that do not use diagnostic criteria and the lack of specific data on MDD reduces the reliability of estimates and limits their value for policy making.

The use of Tablo continuous veno-venous haemodialysis to rapidly remove lithium in a patient with severe lithium toxicity.

We report a case of severe, life-threatening lithium toxicity in a patient with bipolar I disorder who presented with altered mental status and acute renal failure. At admission, serum lithium level was well above toxic levels (>2 mEq/L). The signs and symptoms of lithium toxicity significantly improved after treatment with continuous veno-venous haemodialysis (CVVHD). The patient was discharged with no neurological or renal sequelae. Herein is the first case report using the Tablo CVVHD system to treat severe lithium toxicity.

Efficacious retrial of electroconvulsive therapy for major depressive disorder after a prolonged seizure in an older adult.

This is a case of a woman in her 70s with treatment-resistant major depression who was admitted psychiatrically for the fifth time in 1.5 years. She had a history of intensive psychotherapy and psychotropic medication trials with poor efficacy. She also had a history of adverse complications to electroconvulsive therapy (ECT) with prolonged seizures and postictal confusion during her third hospitalisation. At her fifth hospitalisation, due to poor response to routine psychiatric treatment, ECT was pursued. We discuss challenges in pursuing ECT and the outcome of the retrial of an acute ECT series, in the context of a paucity of similar literature regarding geriatric depression.

Visual hallucinations following electroconvulsive therapy for major depressive disorder.

A female geriatric patient with major depressive disorder, current episode severe, received eight right unilateral electroconvulsive therapy (ECT) treatments over the course of 3 weeks. After her third treatment, she began experiencing brief visual hallucinations, each lasting less than 5 s, consisting of dark to grey coloured, poorly defined geometric shapes and objects. These episodes occurred only during the day with no change in consciousness. With each additional treatment, the episodes increased in frequency, reaching a crescendo of approximately 20 episodes per day. After terminating ECT, the frequency of these episodes decreased and then ceased 6 weeks later. Neuroimaging and ophthalmological investigations discounted a space occupying lesion or vision loss. This case demonstrates a close temporal relationship between ECT and new onset visual hallucinations. Clinicians should be aware of the possibility that elderly depressed patients may develop visual hallucinations during a course of ECT.

Haloperidol-induced isolated lingual dystonia.

A 28-year-old woman presenting with agitation and mania with psychotic features developed symptoms of isolated lingual dystonia shortly after the initiation of a haloperidol concentrate regimen.

Lithium-induced ECG modifications: navigating from acute coronary syndrome to Brugada syndrome.

Lithium is frequently used in the treatment of bipolar disorders and is known to induce ECG alterations. This case study describes various patterns of lithium-induced ECG modifications in a patient with acute-on-chronic lithium intoxication. Clinicians should be familiar with this problem as it can have life-threatening consequences and lead to important changes in patient's management. Our patient was admitted for acute delirium with an ECG showing atrial fibrillation with wide QRS and ST-segment elevation. These modifications were first mistaken for an acute myocardial infarction and a diagnosis of Brugada syndrome was finally reached. Treatment after the acute phase implied changes in the therapeutic modality and required frequent monitoring.

Nicotinic ganglionic acetylcholine receptor autoantibodies associated with paraneoplastic disease in a neuropsychiatric patient.

Nicotinic ganglionic acetylcholine receptor autoantibodies (alpha-3-AChR Ab) are associated with paraneoplastic syndromes when present in low elevations. These antibodies can be tested for as part of an autoimmune encephalopathy panel in neuropsychiatric patients; a mildly elevated titre of alpha-3-AChR Ab that may start as an incidental finding can lead to the diagnosis of a previously undetected cancer. While alpha-3-AChR Ab are most typically associated with thymomas and small cell lung cancer, the presence of these antibodies can suggest a diverse range of other cancers. This case presents a patient with longstanding neuropsychiatric symptoms and possible functional hypothyroidism for whom a low elevation in alpha-3-AChR Ab led to the finding of papillary thyroid carcinoma.

Episode of mixed mood with psychotic features secondary to Binswanger disease: a case report with a literature review.

Neurodegenerative and mood disorders in the geriatric population might exhibit interchangeable cognitive and behavioural symptoms. This overlap in presentation might raise a diagnostic challenge for psychiatrists evaluating elderly patients who are presenting with such symptoms. Additionally, there is limited data published about early psychiatric manifestations of neurodegenerative disorders in the elderly. We report a case of a 71-year-old with a history of refractory depressive disorder and multiple cardiovascular risk factors presenting with verbalisation of suicidal and homicidal intent as well as mixed mood and psychotic symptoms. The patient was diagnosed with Binswanger's disease (BD). We also provide a literature review of challenging early psychiatric presentations of neurocognitive disorders and a summary of similar cases to help facilitate diagnosis of BD cases in future.

Successful electroconvulsive therapy for depression in a man with cerebral amyloid angiopathy.

Cerebral amyloid angiopathy (CAA) is a condition characterised by accumulation of amyloid beta protein (Aß) in the wall of cerebral blood vessels which increases the risk of intracranial haemorrhage and contributes to cognitive impairment. We describe the case of a man around the age of 70 with 'probable' CAA according to the modified Boston criteria and severe depression whose depression was treated successfully with electroconvulsive therapy (ECT). To the best of our knowledge, there are no earlier published reports of ECT in a patient with CAA. We briefly discuss possible safety measures for these patients, the impact of ECT on cognition in CAA and a possible influence of ECT on Aß clearance.

Treatment of a self-inflicted intracranial nail gun injury.

A 30-year-old man walked into the emergency department after a suicide attempt by firing a nail from a pneumatic nail gun directed at his left temple. He was haemodynamically stable and neurologically intact, able to recall all events and moving all extremities with a Glascow Coma Scale of 15. CT of the brain showed a 6.3 cm nail in the right frontal region without major intracerebral vessel disruption. He was taken to the operating room for left temporal wound washout, debridement of gross contamination and closure with titanium cranial fixation plate. The foreign body was not accessible on initial surgical intervention and was left in place to define anatomy and plan for subsequent removal. Thin slice CT images were used to create 3D reconstructions to facilitate stereotactic navigation and foreign body removal via right craniotomy the following day. The patient tolerated the procedures well and recovered with full neurological function.

PTSD and bipolar II disorder in Fukushima disaster relief workers after the 2011 nuclear accident.

The global threat posed by the COVID-19 pandemic has highlighted the need to accurately identify the immediate and long-term postdisaster impacts on disaster-relief workers. We examined the case of a local government employee suffering from post-traumatic stress disorder (PTSD) and bipolar II disorder following the Great East Japan Earthquake. The complex and harsh experience provoked a hypomanic response such as elated feelings with increased energy, decreased need for sleep and an increase in goal-directed activity, which allowed him to continue working, even though he was adversely affected by the disaster. However, 3.5 years later, when he suffered further psychological damage, his PTSD symptoms became evident. In addition to treating mood disorders, trauma-focused psychotherapy was required for his recovery. Thereafter, we considered the characteristics of mental health problems that emerge in disaster-relief workers, a long time after the disaster, and the conditions and treatments necessary for recovery.

Cognitive behavioural therapy for chronic fatigue and chronic fatigue syndrome: outcomes from a specialist clinic in the UK.

OBJECTIVES: Cognitive behavioural therapy is commonly used to treat chronic fatigue syndrome and has been shown to be effective for reducing fatigue and improving physical functioning. Most of the evidence on the effectiveness of cognitive behavioural therapy for chronic fatigue syndrome is from randomised control trials, but there are only a few studies in naturalistic treatment settings. Our aim was to examine the effectiveness of cognitive behavioural therapy for chronic fatigue syndrome in a naturalistic setting and examine what factors, if any, predicted outcome. DESIGN: Using linear mixed effects analysis, we analysed patients' self-reported symptomology over the course of treatment and at three-month follow-up. Furthermore, we explored what baseline factors were associated with improvement at follow-up. SETTING: Data were available for 995 patients receiving cognitive behavioural therapy for chronic fatigue syndrome at an outpatient clinic in the UK. PARTICIPANTS: Participants were referred consecutively to a specialist unit for chronic fatigue or chronic fatigue syndrome. MAIN OUTCOME MEASURES: Patients were assessed throughout their treatment using self-report measures including the Chalder Fatigue Scale, 36-item Short Form Health Survey, Hospital Anxiety and Depression Scale and Global Improvement and Satisfaction. RESULTS: Patients' fatigue, physical functioning and social adjustment scores significantly improved over the duration of treatment with medium to large effect sizes (|d| = 0.45-0.91). Furthermore, 85% of patients self-reported that they felt an improvement in their fatigue at follow-up and 90% were satisfied with their treatment. None of the regression models convincingly predicted improvement in outcomes with the best model being (R2 = 0.137). CONCLUSIONS: Patients' fatigue, physical functioning and social adjustment all significantly improved following cognitive behavioural therapy for chronic fatigue syndrome in a naturalistic outpatient setting. These findings support the growing evidence from previous randomised control trials and suggest that cognitive behavioural therapy could be an effective treatment in routine treatment settings.

Neurotropism of SARS-CoV-2: COVID-19 presenting with an acute manic episode.

A 41-year-old man with no significant medical history presented with acute behavioural disruption on the background of a 1-day history of severe headache and a 10-day history of dry cough and fever. He was sexually disinhibited with pressured speech and grandiose ideas. His behaviour worsened, necessitating heavy sedation and transfer to intensive care for mechanical ventilation despite no respiratory indication. Investigations confirmed that he was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Neuroimaging and a lumbar puncture were normal. Initial screening for SARS-CoV-2 in the cerebrospinal fluid was negative although no validated assay was available. The patient's mental state remained abnormal following stepdown from intensive care. Psychiatric assessment found features consistent with acute mania, and he was detained under the Mental Health Act. This case indicates the need to consider COVID-19 in a wider series of clinical presentations and to develop a validated assay for SARS-CoV-2 in the cerebrospinal fluid.

Natural recovery from long-lasting generalised dissociative amnesia and of cerebral blood flow.

A 40-year-old man presented with generalised dissociative amnesia. At 2 weeks after onset, N-isopropyl-[123I] p-iodoamphetamine-single-photon emission CT imaging of the brain revealed hypoperfusion in the right medial temporal area. Organic brain damage was ruled out. His inability to recall information was attributed to psychological stress related to his employment. Consistent with this diagnosis, his generalised dissociative amnesia lasted 6 years and 10 months; however, he recovered from amnesia naturally on starting a new job. Perfusion of his right medial temporal area also returned to normal levels. Longitudinal reports for generalised dissociative amnesia with natural recovery are exceedingly rare. It is important to confirm whether dissociative amnesia and cerebral blood flow recover in parallel, even in cases where dissociative amnesia is long-lasting.

A 22q13.33 duplication harbouring the SHANK3 gene: does it cause neuropsychiatric disorders?

A young man with neuropsychiatric problems has a small 22q13.33 duplication. We suggest this causes his condition. His disorder may represent a 22q13.33 behavioural phenotype. In childhood, he was diagnosed with mild intellectual disability. He was later diagnosed with Tourette syndrome, atypical autism spectrum disorder and bipolar disorder. Lithium seems effective in treating his affective symptoms. He has mild dysmorphic features, full lips and protruding ears. An array comparative genomic hybridisation showed a 300 kb duplication. The duplication harbours several genes, notably SH3 and multiple ankyrin repeat domain 3 (SHANK 3). The small size helps focus on a critical region for a 22q13.33 duplication syndrome. Mutations, deletions and duplications should be kept in mind as causes of neuropsychiatric disorders, especially in a patient with dysmorphic traits.

Acute suicidal ideations responsive to hydromorphone.

A 72-year-old woman with suicidal ideations for the first time was seen for a follow-up medical visit. Patient diagnosed with bipolar disorder II, chronic complex pain and other complex medical issues. Patient was on long-standing chronic opioid agonist therapy. Patient was prescribed oral hydromorphone to supplement her chronic opioid regimen. Within 24 hours, the patient reported no further suicidal ideations and there were no reported complications. The case provides impetus for further study as to what interventions work best for patients who present with acute suicidal ideations. The case acknowledges cultural issues and implicit biases that can influence medical care and perceptions thereof. Implicit biases may be particularly apparent as they relate to mental health concerns and the use of substances that are susceptible to abuse. The most important clinical lesson reminder may be the importance of adequate documentation and discussion be provided when one prescribes an opioid in a novel way in a special clinical context.

Managing psychotic depression and diagnostic uncertainty in liaison psychiatry.

A middle-aged woman presented with a history of symptoms of depression with psychotic features severely affecting her physical health. Neuroimaging of her brain suggested pathological changes out of keeping with her age, leading to further investigations including genetic testing for cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis was also considered as a differential diagnosis as an initial serum test for anti-NMDAR autoantibodies was positive. Her symptoms resolved following treatment with electroconvulsive therapy. Despite her initial neuroimaging, her genetic test for CADASIL was negative and her subsequent test for anti-NMDAR autoantibodies was negative, suggesting that the initial test may have been a false positive.

Lithium neurotoxicity presenting as dementia with therapeutic serum lithium levels.

After 25 years of continuous lithium therapy, a woman with moderate intellectual disability and bipolar disorder developed symptoms suggestive of dementia. In fact, she had developed lithium neurotoxicity, but this was overlooked for 18 months as serial lithium levels were in the therapeutic range.
