First-line treatments
Dietary counseling and physical activity plan
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Facial muscle rehabilitation
Targeted exercises and neuromuscular retraining to improve voluntary facial movement control and symmetry through repetitive practice.
Muscle relaxant injections
Botulinum toxin injections to specific facial muscles to reduce involuntary dissociation and improve movement coordination.
Additional treatment options
Neurobehavioral therapy
Cognitive-behavioral approaches to address associated anxiety, self-consciousness, and develop coping strategies for social situations.
psychologicalNeuromuscular agents
Oral muscle relaxants such as baclofen or benzodiazepines may be prescribed to reduce muscle tension and involuntary dissociation.
medicationNeurological assessment
Regular follow-up with neurologist to monitor progression, rule out underlying conditions, and adjust management plan.
