Final answer:
A symptom that leads to suspecting conversion disorder is one that does not align with known medical conditions. Conversion disorder symptoms are usually psychological and don't have a physiological basis that can be identified. A careful evaluation is necessary to distinguish between this disorder and medical conditions.
Step-by-step explanation:
The finding that would lead to a suspicion of conversion disorder rather than another medical cause for the condition is c) Symptoms inconsistent with known medical conditions. Conversion disorder is a mental condition in which a person has blindness, paralysis, or other neurologic symptoms that cannot be explained by medical evaluation. Symptoms may occur because of emotional distress or psychological conflict. They are not under the person's conscious control and can be very disruptive. This condition is distinguished from other medical conditions by the presentation of symptoms that are incongruent with, or not fully explained by, known anatomical paths and physiological mechanisms.
In contrast, symptoms that are consistent over time, have a gradual onset, or respond to medication, are often more indicative of medical conditions with an identifiable physical basis. In clinical practice, it is crucial to perform a thorough evaluation to exclude medical conditions before diagnosing conversion disorder.
