    ABSTRACT: Cranial movement disorders are a common neurological problem. These disorders can be limited to the cranial muscles alone or manifest as part of a more generalized movement disorder. Cranial movement disorders can originate from the highest (motor cortex) to the lowest (cranial nerve and muscle) levels of the motor system. Owing to the lack of diagnostic tests and biomarkers for these disorders, their differential diagnosis can be difficult even for the experienced neurologist. Advances have, however, been made in the identification and treatment of these conditions, and most can be managed effectively with appropriate knowledge of the diagnostic signs and effective treatments. Here, we review the clinical features, pathophysiologies and therapies of the main movement disorders that affect the face, jaw, tongue and palate.

    ABSTRACT: We hypothesize that a smaller posterior fossa (PF) CSF space may be a risk factor for hemifacial spasm (HFS). We conducted a case-control 3-dimensional magnetic resonance (MR) volumetric study in patients with HFS and determined the clinical predictive factors of PF CSF volume. Patients with clinically diagnosed HFS and controls matched for age, sex, race, and hypertension underwent MRI/magnetic resonance angiography examination. The PF CSF space was segmented and quantified on a heavily T2-weighted high-resolution 3-dimensional MR volume slab, centered over the porus acusticus. Eighty-two study subjects (41 patients and 41 controls) were included. The mean PF CSF volume in patients with HFS and controls was 17,303.0 +/- 3,900.0 vs 19,216.0 +/- 3,912.0 mm(3). The mean volume in patients with HFS was 11.4% smaller than in controls (p = 0.015). Analysis of differences between individually matched pairs and controls also revealed that PF CSF for controls was larger than that for patients with HFS (p = 0.007). A multivariate linear regression analysis revealed that a small PF CSF volume was associated with HFS (p = 0.01). Decreasing age (p = 0.001) and female gender (p < 0.0005), but not hypertension (p = 0.892), were also found to be predictors of a low PF CSF volume. Our results showed that the posterior fossa (PF) CSF volume was lower in patients with HFS compared with matched controls. HFS, female gender, and younger age were associated with smaller PF CSF volume. These observations could explain the strong female preponderance in both clinic- and population-based epidemiologic studies.
