What are two examples of idiopathic disorders?

Idiopathic disorders are conditions with no identifiable cause. Two examples include idiopathic pulmonary fibrosis, a progressive lung disease characterized by scarring of lung tissue, and idiopathic thrombocytopenic purpura, an autoimmune disorder that leads to a low platelet count and increased risk of bleeding. In both cases, the underlying mechanisms remain unclear despite extensive research.
