What term describes the pattern of development and change of a disorder over time?

The term that describes the pattern of development and change of a disorder over time is prognosis. Prognosis refers to the anticipated course and outcome of a condition, including how it may fluctuate, improve, or worsen as time progresses. This concept takes into account various factors such as the nature of the disorder, individual patient characteristics, and responses to treatment.

Understanding prognosis is crucial in clinical settings, as it helps healthcare providers and patients set realistic expectations, plan appropriate interventions, and track progress over time. It contrasts with the other terms, which are more focused on causation, identification, or treatment strategies rather than the developmental trajectory of a disorder.
