Marchiafava-Bignami disease

Last edited: 4/23/2026

Overview

Marchiafava-Bignami disease (MBD) is a rare neurological disorder primarily associated with chronic alcohol abuse, characterized by corpus callosum atrophy and often accompanied by cognitive deficits, disturbed consciousness, dysarthria, and motor impairments including tetraparesis and astasia-abasi 1.

Diagnosis

  • Clinical Features: Chronic alcohol abuse history, symmetrical corpus callosum lesions, disturbed consciousness, dysarthria, tetraparesis, astasia-abasia, and cognitive decline 1.
  • Imaging: Susceptibility-weighted imaging (SWI) can detect cerebral microhemorrhages (CMH) in multiple cortico-subcortical regions, indicative of MBD 1.
  • Management

  • Primary Intervention: Cessation of alcohol consumption is crucial 1.
  • Supportive Care: Management of symptoms including physical therapy for motor deficits and cognitive rehabilitation for dementia 1.
  • No Specific Pharmacological Treatment: No specific drug classes or doses are mentioned for MBD treatment 1.
  • Special Populations

  • Chronic Alcohol Abuse: All reported cases involve chronic alcohol abuse, highlighting the necessity of addressing alcohol use disorder across all age groups 1.
  • Key Recommendations

  • Utilize SWI for Diagnosis: Incorporate susceptibility-weighted imaging to identify cerebral microhemorrhages in suspected MBD cases (Evidence: Moderate) 1.
  • Prioritize Alcohol Cessation: Emphasize cessation of alcohol consumption as the primary intervention for patients diagnosed with MBD (Evidence: Expert opinion) 1.
  • Monitor Cognitive Decline: Regularly assess cognitive function in MBD patients, particularly noting the association between CMH and dementia progression (Evidence: Moderate) 1.
