A client exhibits sudden blindness with no organic cause following a traumatic incident. This condition is likely indicative of what disorder?

The situation described, where a client experiences sudden blindness with no apparent organic cause following a traumatic incident, is most indicative of conversion disorder. Conversion disorder, which falls under somatic symptom disorders in the DSM-5, is characterized by neurological symptoms that cannot be explained by medical conditions. In this case, the blindness serves as a psychological response to trauma, reflecting the individual's inner emotional conflicts or stressors manifesting as physical symptoms.

Clients with conversion disorder usually experience significant distress related to these symptoms and may not consciously choose to produce them. The sudden onset of blindness in connection with the traumatic incident underscores the link between psychological factors and physical symptoms present in conversion disorder. This disorder often presents in a dramatic fashion, similar to what is observed in this client, reinforcing its diagnosis.

Conversely, other disorders mentioned do not directly correlate with the acute, physical manifestation of symptoms in response to trauma as conversion disorder does. Psychosis involves a disconnection from reality and often includes symptoms like hallucinations or delusions, which are not part of this scenario. Dissociative disorders often relate to memory or identity disruption rather than the physical symptoms exhibited here. Repressive disorder is not a recognized term in current psychological nomenclature. Thus, conversion disorder is the most fitting diagnosis
