Occlusions are often considered an obstacle or blockage in different situations. Synonyms for occlusions include blockages, obstructions, impediments or hindrances. These terms can refer to physical or abstract barriers that prevent something from proceeding as intended. For instance, plaque buildup in arteries can create an occlusion, restricting blood flow. In speech therapy, an occlusion can occur when patients have difficulty producing sounds due to restrictions in their vocal tract, creating a speech blockage. Mental health professionals also use the term to describe a form of cognitive bias where people focus on negative events or ignore positive ones, hindering their positive outlook. By using alternative words for occlusions, we can better describe different situations and the impact of obstacles.
