![]() ![]() When you have an infection from a bacteria, the underlying cause is etiology. For example, when you have an infection from a virus, the underlying cause is pathogenesis. In the medical field, pathogenesis is used to classify the disease. However, pathogenesis and etiology are different. For example, when you eat a food containing a toxin or a virus, you may experience negative effects. It explains how and why a disease developed. Pathogenesis is the underlying cause of a disease. For example, when you eat a food containing a toxin, you may experience these negative effects. It explains how and why a disease developed in its initial stage. However, they have different applications.Įtiology is the origin of a disease. The two terms pathogenesis and etiology are quite similar. The difference between etiology and pathogenesis However, the negative effects are not caused by the food. These negative effects are caused by the food containing a toxin or a virus. For example, when you eat a food containing a toxin or a virus, you may experience negative effects like: When the underlying cause of a disease isn’t known, it can be classified as etiology. However, the positive effects are not caused by the food itself. These positive effects are caused by the food containing a toxin or virus. For example, when you eat a food that contains a toxin or a virus, you may experience positive effects like: When the underlying cause is known, it can be classified as pathogenesis. ![]() It explains how and why a disease develops. Pathogenesis refers to the underlying cause of a disease. These positive effects are caused by eating the food. It explains how and why the disease developed in its initial stage.įor example, when you eat a food, you may experience positive effects like: However, the effects are not caused by the alcohol itself.Įtiology is the origin of a disease. These negative effects are caused by drinking alcohol. A cause is something or a situation that is responsible for causing an effect.įor example, when you drink alcohol, you may experience negative effects like: Causes and effectsĪ cause is a reason for an effect to occur. To understand the difference between pathogenesis and etiology, it’s essential to understand the difference between cause and effect. It explains how the disease developed in its initial stage. We propose more focused studies that examine the role of the immune system together with characterized pathogenesis to determine when, where, and if immune and inflammatory processes are critical to disease progression, and thus worthy targets of intervention.Pathogenesis refers to the underlying cause of a disease. Although immune system components may indeed play a role in ALS pathogenesis, studies implicating immune cells, antibodies, and cytokines in early disease pathology are limited. Herein we discuss the potential role of the immune system in ALS pathogenesis and critically review evidence from patient and animal studies. It is apparent that new paradigms must be investigated to understand the effectors of ALS, including inflammation, immune responses, and the body's response to stress and injury. Charcot first described ALS in 1869 1 however, its pathogenesis remains unknown, and effective treatments remain elusive. Amyotrophic lateral sclerosis (ALS) is a severely debilitating disease characterized by progressive degeneration of motor neurons. ![]()
