Terminal illness refers to a disease or medical condition that is incurable and is expected to result in the patient’s death within a relatively short period. Patients diagnosed with a terminal illness typically have a prognosis indicating a limited lifespan, often measured in months or years. Terminal illnesses may include advanced stages of cancer, neurodegenerative diseases, or end-stage organ failure. Individuals with terminal illnesses often require specialized palliative or hospice care to manage symptoms, provide comfort, and support quality of life during their remaining time. Medical decisions for patients with terminal illnesses often focus on alleviating suffering and ensuring dignity in the final stages of life.
