A Rare Case Of Sub-Acute Form Of Marchiafava-Bignami Disease Presenting Predominantly With Psychotic Symptoms

Objective: The objective is to present a rare case of sub-acute form of Marchiafava-Bignami disease presenting with psychosis, minimal cognitive impairment and no clinical neurological signs. Methods: This is a case report of a patient with Marchiafava-Bignami disease presenting to a tertiary care psychiatric hospital in Singapore. A review of the literature of the condition is also presented. Results: The patient presented with prominent psychotic symptoms in the context of chronic alcohol abuse. He also had minimal cognitive impairment and clinically no neurological signs. A working diagnosis of alcohol induced psychotic disorder was made. His psychotic symptoms seemed to be resistant to treatment with antipsychotic medications initially and this led to further investigation by MRI scan of brain which revealed atrophy of corpus callosum and no other significant abnormalities. His psychotic symptoms gradually improved with treatment. He is now placed in an intermediate care setting in the hospital while waiting for a suitable community placement. Conclusions: It is rare for Marchiafava-Bignami disease to present with prominent psychotic symptoms with minimal cognitive impairment and no neurological signs clinically. In patients with a history of chronic alcohol abuse presenting with psychotic disorder, Marchiafava-Bignami disease should be suspected as a diagnostic possibility.

A case of prolonged delirium tremens

We present a case of delirium tremens lasting for five weeks in an alcohol-dependent individual. The patient required high-dose benzodiazepines, which is atypical and rare. The clinical presentation and management of this patient is discussed.

Prolonged Delirium Secondary to Hypoxic-ischemic Encephalopathy Following Cardiac Arrest

Hypoxic-ischemic brain injury encompasses a complex constellation of pathophysiological and cellular brain injury induced by hypoxia, ischemia, cytotoxicity, or combinations of these mechanisms and can result in poor outcomes including significant changes in personality and cognitive impairments in memory, cognition, and attention. We report a case of a male patient with normal premorbid functioning who developed prolonged delirium following hypoxic-ischemic brain insults subsequent to cardiac arrest. The case highlights the importance of adopting a multidisciplinary treatment approach involving the coordinated care of medical and nursing teams to optimise management of patients suffering from such a debilitating organic brain syndrome.
