[Wernicke Encephalopathy In Refeeding Syndrome]

Area of Science:

• Neurology
• Psychiatry
• Internal Medicine

Background:

• Recurrent depressive disorder and restrictive anorexia nervosa can coexist.
• Malnutrition from anorexia nervosa poses risks during depressive episodes.
• Refeeding syndrome is a critical complication in nutritional rehabilitation.

Purpose of the Study:

• To describe a case of Wernicke encephalopathy secondary to refeeding syndrome.
• To highlight the pathophysiology linking anorexia, depression, and thiamine deficiency.
• To emphasize the importance of early diagnosis and management of Wernicke encephalopathy in malnutrition.

Main Methods:

• Case report of a patient with a history of recurrent depressive disorder and anorexia nervosa.
• Analysis of clinical presentation, metabolic state, and neurological symptoms.
• Review of pathophysiology related to thiamine metabolism during refeeding.

Main Results:

• A patient developed Wernicke encephalopathy during refeeding for anorexia nervosa, precipitated by a depressive episode with increased appetite.
• The condition was linked to rapid thiamine consumption during the transition to an anabolic state.
• Nonspecific symptoms in malnourished patients can mask Wernicke encephalopathy.

Conclusions:

• Wernicke encephalopathy is a potential complication of refeeding syndrome in patients with anorexia nervosa and depression.
• Early recognition of nonspecific symptoms in malnutrition is vital.
• Immediate B1 vitamin and electrolyte replacement, alongside nutritional support, is essential to prevent irreversible damage.
