Late-onset delirious mania: Does it ring a bell?

BACKGROUND: Bell's mania was first described in 1849, and other terms have been used to describe this condition, including delirious mania, mania with delirium, and excited delirium. However, no international diagnostic manual has included mania as an independent diagnostic tool. The criteria for delirious mania were proposed by Bond et al. METHODS: We present a case of a man without a personal or family psychiatric history who experienced his first manic episode of delirium and psychosis at 76 years old. CONCLUSIONS: The case described in this study is compatible with mood disorders, the original description of Bell's mania, and Bond's definition of delirious mania. Although rare, extremely late-onset primary mania can occur without personal or family psychiatric history. The initial clinical presentation of delirium requires a thorough medical investigation, including magnetic resonance imaging (MRI) and lumbar puncture with neuronal antibodies. The addition of delirious mania to the group of bipolar disorders in future editions of The International Classification of Diseases (ICD) and Diagnostic and Statistical Manual of Mental Disorders (DSM) has therapeutic and prognostic implications. The Bond criteria can provide valuable information in this respect. Further investigations are necessary to clarify the pathophysiology and epidemiology of delirious mania.

Risk factors for suicide among patients having received treatment with electroconvulsive therapy: A nationwide study of 11,780 patients.

OBJECTIVES: Despite the putative anti-suicidal effect of electroconvulsive therapy (ECT), patients receiving ECT remain at high risk of dying from suicide due to the severity of their underlying mental illness. We aimed to quantify this risk and to identify risk factors for suicide among patients receiving ECT. METHODS: Using nationwide Danish registers, we identified all patients that initiated ECT between 2006 and 2016. These patients were matched on sex and age to 10 reference individuals from the general Danish population. Firstly, we compared 2-year suicide risk between patients initiating ECT and the matched reference individuals. Secondly, we investigated if any patient characteristics were associated with suicide following ECT via Cox proportional hazards regression. RESULTS: A total of 11,780 patients receiving ECT and 117,800 reference individuals were included in the analyses. Among the patients receiving ECT, 161 (1.4%) died from suicide within two years. Compared to the reference individuals, patients having received ECT had a substantially elevated suicide rate (Hazard rate ratio (HRR) = 44.48, 95%CI = 31.12-63.59). Among those having received ECT, the following characteristics were associated with suicide: Male sex (adjusted HRR (AHRR) = 2.32, 95%CI = 1.63-3.30), medium-term higher education (AHRR = 2.64, 95%CI = 1.57-4.44); long-term higher education (AHRR = 3.16, 95%CI = 1.68-5.94), history of substance use disorder (AHRR = 1.51, 95%CI = 1.01-2.26) and history of intentional self-harm/suicide attempt (AHRR = 4.18, 95%CI = 2.76-6.32). CONCLUSIONS: Those who are male, have obtained medium-/long-term higher education, or have a history of substance use disorder or intentional self-harm/suicide attempt, are at particularly elevated risk of suicide following ECT. These findings may guide clinical initiatives to reduce suicides.
