While there is no cure for Tourette syndrome, there are several available options to treat severe tics. These include behavioral (e.g. psychotherapy and cognitive behavioral therapy), pharmacological (e.g. medications that block dopamine in the brain), and more intrusive surgical interventions (e.g. deep brain stimulation, whereby motor areas of the brain receive electrical stimulation). However, the efficacy of these treatments can vary, and patients still frequently suffer from physical, mental, and social disabilities. As an alternative treatment option, researchers at Osaka University have developed a custom-made oral splint. These are typically used for unconscious teeth clenching and grinding, and for temporomandibular disorders such as misalignment of the teeth or jaw. The oral splint is applied to the molars to increase the occlusal vertical dimension, which essentially means that the alignment of the nose, lips, and chin is altered. The study was recently published in Movement Disorders.
