Diagnosis is similar, but slightly different for each type of PD. Some types are more understood than others, and therefore have more criteria for diagnosis. PKD The guidelines for diagnosing PKD were reviewed and confirmed by Unterberger and Trinka. PKD consists of unexpected forms of involuntary movements of the body. The patient is usually diagnosed sometime before their 20s, and is more likely diagnosed during childhood than early adulthood. Almost all PKD's are idiopathic, but there have been examples of autosomal dominant inheritance as well. Physical examination and brain imaging examinations show normal results, and an EEG shows no specific abnormalities as well. However, the negative synchronous EEG results can be used to prove that PKD is not a sort of reflex epilepsy, but a different disease. PKD is the most prevalent subtype of<unk> , encompassing over 80% of all given PD diagnosis. PKD is more prevalent in boys, usually as high as 3.75:1. PNKD PNKD has a set guideline for diagnosis that is slightly different from PKD. PNKD usually occurs unexpectedly, and is not brought on by sudden movements or exercise. Instead the attacks are brought on by stresses such as emotional stress, fatigue, alcohol, or caffeine consumption. Just like PKD, PNKD also shows autosomal dominance in family history. Physical examination and brain imaging examinations show normal results, and EEG shows no specific abnormalities as well. PNKD is more prevalent in boys, with ratios of 1.4:1. PED PED has a set guideline for diagnosis that is similar, but slightly different from both PKD and PNKD. PED attacks consist of dystonic and bilateral movements usually in the lower limbs of the body. These attacks are usually brought about only by exercise and physical exhaustion. PED patients do not feel an aura-like sensation before an attack occurs, unlike PKD and PNKD. These attacks usually last from 5 to 30 minutes, and can occur once a day or once a month. Physical examination and brain imaging examinations show normal results, and EEG shows no specific abnormalities as well. PED is the rarest<unk>  subtype.
