| A rare neurodegenerative disease characterized by extrapyramidal symptoms (rigidity, tremor, bradykinesia) and dementia, typically beginning in the fifth or sixth decade of life and progressing to a vegetative state with pelvicrural flexion contractures within few years. Oculomotor signs, olfactory dysfunction, and autonomic disturbances may also be observed. Neuropathological hallmarks are frontotemporally accentuated cerebral atrophy, as well as neurofibrillary tangles and neuronal loss in a characteristic distribution in cortical and subcortical regions. The disease is endemic to the Pacific Island of Guam. |

| A rare autosomal dominant hereditary axonal motor and sensory neuropathy characterized by predominantly distal weakness and muscle atrophy, decreased or absent tendon reflexes, and reduced vibratory sensation in the lower and upper extremities. Pes cavus develops in many patients. Additional symptoms like ataxia, tremor, or swallowing difficulties have been reported. Patients usually remain ambulatory even late in the disease. Age of onset ranges from childhood to adulthood, with earlier onset tending to be associated with a more severe disease phenotype. |
