The exact combina- tion and severity of these symptoms varies widely between cases and types of prion disease. CJD, the most common of the human prion diseases, is characterized by a rapid deterioration in mental func- tion from confusion and memory loss into severe, accompanied by loss of muscular control (ataxia) and twitching or spasmodic motion (myoclonus). A scan of electrical activity in the brain, called an elec- troencephalogram (EEG), will often show an abnormal periodic spike pattern. The onset of symptoms usually occurs when the patient is over age 50 and death follows within one to five years. Microsopic holes, or vacuoles, in the brain tissue, which give it a “spongiform” appear- ance, are characteristic of CJD. One form of the dis- ease (the ataxic form) is first characterized by an unsteady walk sometimes accompanied by leg pains. These motor problems get worse over several years and are finally accompanied by mental and behavioral break- down. By contrast, dementia is the main characteristic of the telencephalic form of GSS, accompanied by rigidity, the inability to make facial expressions, tremors, and stuttering or stammering. In another form of the disease, GSS with neurofibrillary tangles, the main features are loss of muscle coordination (ataxia), tremors, and pro- gressive insanity. As in CJD, the affected individuals are usually in their fifties or older, and the progression of the disease may take from two to six years. The most noticeable sign of fatal familial insomnia (FFI) is the untreatable and progressively worse difficulty in sleeping. The affected individual then begins to experi- ence complex hallucinations which are often enacted dreams. The onset of symptoms usually blood pressure, and hyperventilation are other symptoms. The average age at The early signs of new variant CJD are most often onset of symptoms is the mid-forties, and the disease pro- psychiatric disturbances. Abnormal sensations of prick- gresses rapidly with death resulting after about one year. The duration Kuru was called the “shivering” disease by the Fore of the disease is one to two years. As in CJD, vacuoles are tribe members because its primary symptom was twitch- present in the brain, but they are associated with dense ing and shaking of the body.

PXE is caused by changes in the genetic material, called mutations, that are inherited in either a dominant or recessive mode. A person with the recessive form of the disease (which is most common) must possess two copies of the PXE to be affected, and, therefore, must have received one from each parent. In the domi- nant form, one copy of the abnormal gene is sufficient to cause the disease. In some cases, a person with the dom- inant form inherits the abnormal gene from a parent with PXE. More commonly, the mutation arises as a sponta- neous change in the genetic material of the affected per- son. These cases are called “sporadic” and do not affect parents or siblings, although each child of a person with sporadic PXE has a 50% risk to inherit the condition. Both males and females can develop PXE, although the skin findings seem to be somewhat more common in females. The recessive, dominant, and spo- radic forms of PXE all appear to be caused by different mutations or deletions in a single gene called ABCC6 (also known as MRP6), located on chromosome 16.
