Functional impairment can arise from various causes, including:
Inflammation: Acute or chronic inflammation can lead to tissue damage and loss of function. Degeneration: Age-related or pathological degeneration affects tissue integrity and function. Neoplasia: Tumor growth can disrupt normal tissue architecture and function. Trauma: Physical injury can cause immediate and long-term functional deficits. Infection: Pathogens can induce cellular damage and inflammatory responses.
