Published: December 2016

Background: Marchiafava-Bignami (MB) disease is a rare disorder that causes primary degeneration of the corpus callosum. It is associated with chronic alcohol consumption caused by either a toxic or nutritional etiology.

Case Report: We report a case of a 54-year-old woman who presented to our emergency department with complete mutism caused by MB disease that completely resolved with intravenous thiamine and dextrose therapy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians frequently encounter patients with alcohol abuse and its complications. We report a rare presentation of a potential alcohol-related spectrum disease that may be encountered by an emergency physician. Early diagnosis and prompt management are critical to potentially reversing the disease, and this case shows the importance of including this disease in the differential diagnosis in patients with speech difficulty and alcohol abuse.

Cerebellar mutism syndrome (also known as posterior fossa syndrome) has been mostly seen in pediatric patients after surgery for neoplastic disease and is characterized by mutism, with variable symptoms such as emotional lability, ataxia, apraxia, and hypotonia. While the mechanism is not precisely defined, it is thought to result from disconnections between the cortical and cerebellar brain networks. Presentation in adult patients is rare, with various etiologies including posterior fossa ischemia, hemorrhage, and tumors being most reported.

Catatonia is a serious neuropsychiatric syndrome of motor and behavioral dysfunction where electroconvulsive therapy (ECT) is a well-proven treatment modality. ECT is also preferred as it is a low-risk procedure compared to chronic medications having significant side effects. However, the cardiovascular events that occur during ECT are a major cause of morbidity and mortality in patients with an abnormal cardiovascular pathophysiology.

This is the case of a 22-year-old female who arrived at our institution after experiencing refractory insomnia, disorganized behavior, inappropriate laughter, and anorexia. Upon admission, a physical examination revealed mutism, irritability, and visual hallucinations. Infectious, metabolic, and other, alternative, causes for the presenting symptoms were excluded.

Article Synopsis
  • - Creutzfeldt-Jakob disease (CJD) is a rare and fatal brain disorder that typically affects people in their 60s and manifests as rapid cognitive decline due to the accumulation of abnormal prion proteins, leading to death within a year of diagnosis.
  • - Diagnosis of CJD is complicated by overlapping symptoms with other degenerative and infectious diseases, requiring a comprehensive approach that includes clinical evaluations and advanced imaging techniques.
  • - A case study of a 60-year-old man with probable sporadic CJD highlights symptoms such as dementia and rigidity, as well as MRI findings that indicate severe neurodegeneration, demonstrating the need for early identification for palliative care, since there is no effective treatment.
