A terminal illness is a medical condition that is expected to lead to a person's death within a specific time frame, often within six months to a year. These illnesses can include various types of cancer, advanced heart disease, or neurological disorders like Alzheimer's disease. Patients with terminal illnesses typically experience a decline in health and may require palliative care to manage symptoms and improve their quality of life. Diagnosis of a terminal illness can be emotionally challenging for both patients and their families. It often leads to discussions about end-of-life care, including options like hospice services, which focus on comfort rather than curative treatment. Support from healthcare professionals, family, and friends is crucial during this difficult time.
