In the scenario described, Andy experiencing sudden blindness with no physical cause found suggests a psychological issue rather than a physical one. Given the details provided, the likely disorder classifying Andy's experience is conversion disorder.
Here's why conversion disorder is the probable classification:
1. Conversion Disorder: This disorder involves experiencing physical symptoms, like blindness, that have no clear physical explanation. The symptoms are thought to be a manifestation of psychological distress or conflict. In Andy's case, the sudden onset of blindness without any apparent medical cause aligns with the characteristics of conversion disorder.
2. Resolution of Symptoms: Conversion disorder symptoms can often resolve with psychological intervention or counseling, as seen in Andy's situation where the blindness vanished after undergoing psychotherapeutic counseling sessions with a psychiatrist.
In conclusion, based on the sudden onset of blindness with no physical evidence and the subsequent resolution after psychological intervention, conversion disorder is the disorder that likely classifies Andy's experience.
