Overview

The majority of patients with [disease name] are asymptomatic.

OR

The hallmark of [disease name] is [finding]. A positive history of [finding 1] and [finding 2] is suggestive of [disease name]. The most common symptoms of [disease name] include [symptom 1], [symptom 2], and [symptom 3]. Common symptoms of [disease] include [symptom 1], [symptom 2], and [symptom 3]. Less common symptoms of [disease name] include [symptom 1], [symptom 2], and [symptom 3].

History and Symptoms

History

• Drug history
• Diet history
• History of volume loss: diarrhea, vomiting

Common Symptoms

• Asymptomatic
• Acute neurologic changes (seizures, altered mental status, coma or focal neurologic signs)

• Moderate symptoms
  • Nausea
  • Headache
  • Confusion
  • Loss of energy and fatigue
  • Restlessness and irritability

• Severe
  • Vomiting
  • Cardio-respiratory distress
  • Abnormal and deep somnolence
  • Seizures
  • Coma (Glasgow Coma Scale B8
  • Delirium
  • Impaired consciousness

• Mild chronic hyponatremia (plasma sodium 125–135 mEq/L) may cause subtle neurocognitive deficits that can only be detected by careful testing; these deficits improve when the plasma sodium is normalized.

Less Common Symptoms

• cardiorespiratory arrest
