<unk>  is a neuronal disease, meaning it affects the nervous system, specifically voluntary movement and intellectual function. Symptoms of<unk>  can manifest anytime between adolescence and adulthood, however it usually appears around age 30. There are two types of<unk> : Type A and Type B. Type A causes seizures, myoclonic epilepsy (muscle jerks), dementia, ataxia (compromised muscle coordination), tremors and tics, dysarthria (speech difficulties), confusion, and psychotic behaviour. Although similar to Type A, patients with Type B do not suffer from myoclonic epilepsy or dysarthria, and they do display changes in personality. It is occasional that patients present with skin disorders causing dryness, roughness, and scaliness. The skin symptoms specifically, are a result of keratin buildup in the skin cells (see ‘Genetic causes’ for more information). Regardless of the type, most<unk>  patients do not survive more than 15 years after their symptoms have manifested.
