La Belle Indifference is a term used to describe a lack of concern or distress about physical symptoms that are typically associated with a conversion disorder. Signs and symptoms of La Belle Indifference may include:
- Lack of emotional distress or concern about physical symptoms, such as blindness, paralysis, or other nervous system symptoms.
- Inconsistency in the person's signs and symptoms when performing activities and when being examined.
- Variable strength of weakness at different locations.
- Co-contraction of muscles, where both the triceps and biceps muscles contract when asked to bend the elbow.
- Tremor changes when the person is distracted.
- Variation in the pattern of tremor.
- Tremor syncing with rhythmic movements or sounds.
It is important to note that La Belle Indifference is not a diagnostic criterion for conversion disorder, but rather an observation of a specific type of response to physical symptoms. A complete physical and neurological examination is necessary to rule out other medical and neurological conditions that may present with similar symptoms.
