ICD-10: G93.41

Metabolic encephalopathy, classified under ICD-10 code G93.41, is a significant medical condition characterized by a diffuse brain dysfunction resulting from metabolic disturbances. This condition can arise from various underlying causes, including systemic illnesses, toxic exposures, and metabolic imbalances. Below is a detailed overview of metabolic encephalopathy, including its clinical description, causes, symptoms, diagnosis, and treatment options.

Clinical Description

Metabolic encephalopathy refers to a state of altered mental status and neurological function due to metabolic derangements. It is not a specific disease but rather a syndrome that can manifest in various clinical settings. The brain's function is heavily reliant on a stable metabolic environment; thus, any significant disruption can lead to neurological impairment.

Pathophysiology

The pathophysiology of metabolic encephalopathy involves the brain's response to systemic metabolic disturbances. Common mechanisms include:

• Hypoxia: Reduced oxygen supply can lead to neuronal injury.
• Toxicity: Accumulation of toxins (e.g., ammonia in liver failure) can disrupt neurotransmission.
• Electrolyte Imbalances: Abnormal levels of sodium, potassium, calcium, or magnesium can affect neuronal excitability.
• Hypoglycemia or Hyperglycemia: Fluctuations in blood glucose levels can impair brain metabolism.

Causes

Metabolic encephalopathy can be triggered by a variety of factors, including:

• Liver Disease: Hepatic encephalopathy due to liver failure or cirrhosis.
• Renal Failure: Uremic encephalopathy resulting from the accumulation of waste products.
• Endocrine Disorders: Conditions such as diabetic ketoacidosis or thyroid dysfunction.
• Infections: Sepsis or systemic infections can lead to metabolic derangements.
• Nutritional Deficiencies: Thiamine deficiency (Wernicke's encephalopathy) is a notable example.
• Toxic Exposures: Alcohol, drugs, or heavy metals can induce encephalopathy.

Symptoms

The clinical presentation of metabolic encephalopathy can vary widely but often includes:

• Altered Mental Status: Confusion, disorientation, or decreased consciousness.
