Differential Diagnosis for a 50-year-old Male Heavy Drinker with Recent Weight Loss and Personality Changes

  • Single most likely diagnosis:
    • Wernicke-Korsakoff Syndrome: This condition is a brain disorder caused by a lack of thiamine (vitamin B1) and is commonly seen in heavy drinkers. The recent weight loss and change in behavior (becoming mean and nasty) could be indicative of this syndrome, especially if the patient has been experiencing memory problems, confusion, and difficulty with coordination and balance.
  • Other Likely diagnoses:
    • Alcohol Withdrawal: The patient's history of heavy drinking and recent weight loss could suggest alcohol withdrawal, which can cause irritability, mood swings, and other behavioral changes.
    • Liver Disease: Heavy drinking can lead to liver disease, such as cirrhosis, which can cause weight loss, personality changes, and other systemic symptoms.
    • Depression: The patient's recent weight loss and change in behavior could also be indicative of depression, which is common in individuals with a history of heavy drinking.
  • Do Not Miss diagnoses:
    • Pancreatic Cancer: Although less likely, pancreatic cancer can cause significant weight loss and changes in behavior, especially if the tumor is affecting the pancreas's ability to produce hormones that regulate mood and appetite.
    • Hypothyroidism: Untreated hypothyroidism can cause weight loss, depression, and changes in behavior, and is essential to diagnose and treat to prevent long-term complications.
    • CNS Infection (e.g., meningitis or encephalitis): Infections of the central nervous system can cause rapid changes in behavior, weight loss, and other systemic symptoms, and require prompt diagnosis and treatment to prevent serious complications.
  • Rare diagnoses:
    • Creutzfeldt-Jakob Disease: A rare, degenerative brain disorder that can cause rapid weight loss, changes in behavior, and other neurological symptoms.
    • Wilson's Disease: A rare genetic disorder that can cause liver disease, neurological symptoms, and changes in behavior, especially if left untreated.
