-
A rare genetic human prion disease characterised by adult-onset neurodegenerative manifestations associated with a movement disorder and psychiatric/behavioural disturbances. Patients typically present personality changes, aggressiveness, manias, anxiety and/or depression in conjunction with rapidly progressive cognitive decline (presenting with dysarthria, apraxia, aphasia and eventually leading to dementia) as well as ataxia (manifesting with gait disturbances, unsteadiness, coordination problems), Parkinsonism, myoclonus, and/or chorea. Additional features may include generalised spasticity, seizures, urine incontinence and pyramidal abnormalities. There is evidence the disease is caused by 8 extra octapeptide repeats in the PRNP gene on chromosome 20p13.
