destruction that leads to disease In contrast, familial cases of prion disease are thought to be the result of one of several gene aberrations residing in the region that codes for PrPc Of some interest is the nding by Zanusso and colleagues of the infectious prion protein in the nasal mucosa of all nine patients studied with the sporadic disease This suggests a route for entry into the nervous system of the aberrant prion and also a potential diagnostic test Clinical Features Transmissible SSE is in most cases a disease of late middle age, although it can occur in young adults The sexes are affected equally In the large series of pathologically veri ed cases reported by Brown and coworkers, prodromal symptoms consisting of fatigue, depression, weight loss, and disorders of sleep and appetite lasting for several weeks were observed in about one-third of the patients The early stages of the disease are characterized by a great variety of clinical manifestations, but the most frequent are changes in behavior, emotional response, and intellectual function, often followed by ataxia and abnormalities of vision, such as distortions of the shape and alignment of objects or actual impairment of visual acuity Typically, the early phase of the disease is dominated by symptoms of confusion, with hallucinations, delusions, and agitation In other instances, cerebellar ataxia (Brownell-Oppenheimer variant) or visual disturbances (Heidenhain variant) precede the mental changes and may be the most prominent features for several months Headache, vertigo, and sensory symptoms are complaints in some patients but become quickly obscured by dementia and muteness As a rule, the disease progresses rapidly, so that obvious deterioration is seen from week to week and even day to day Sooner or later, in almost all cases, myoclonic contractions of various muscle groups appear, perhaps unilaterally at rst but later becoming generalized Or, infrequently, the myoclonus may not appear for weeks or even months after the initial mental changes The myoclonus is associated with a striking startle response, mainly to a loud noise In a few patients, a startle response, which is elicitable for a brief period of time, is the only manifestation of myoclonus In general, the myoclonic jerks are evocable by sudden sensory stimuli of all sorts (noise, bright light, touch), but they occur spontaneously as well Twitches of individual ngers are typical but it should be emphasized that well-formed seizures are not a component of the illness These changes gradually give way to a mute state, stupor, and coma, but the myoclonic contractions may continue to the end Signs of degeneration of the pyramidal tracts or anterior horn cells, palsies of convergence and upgaze, and extrapyramidal signs occur in a small number of patients as the disease advances The clinical diagnosis during life rests mostly on the recognition of one of the clusters of typical clinical features, particularly the unique syndrome of dementia which progresses much more quickly than that of common degenerative diseases coupled with stimulus-sensitive myoclonus and the characteristic EEG changes that occur in most patients (see below) The disease is invariably fatal, usually in less than a year from the onset In about 10 percent of patients, the illness begins with almost stroke-like suddenness and runs its course rapidly, in a matter of a few weeks At the other extreme, a small number of patients have reportedly survived for 2 to 10 years, but these cases should be accepted with caution; in some of them, SSE appears to have been superimposed on Alzheimer or Parkinson disease or some other chronic condition that predated the prion illness.

Laboratory Diagnosis The routine CSF and other laboratory tests are normal useful ndings in that they exclude a number of chronic in ammatory causes of dementia In most patients, the EEG pattern is distinctive, changing over the course of the disease from one of diffuse and nonspeci c slowing to one of stereotyped high-voltage slow- (1- to 2-Hz) and sharp-wave complexes on an increasingly slow and low-voltage background (see Fig 2-3G, page 27) The high-voltage sharp waves, which give the appearance of periodicity (pseudoperiodic), are synchronous with the myoclonus but may persist in its absence Imaging studies of the brain had been thought until recently to be of little value, but up to 80 percent of cases show a subtle hyperintensity of the lenticular nuclei on T2-weighted images when the disease is fully established (Fig 335) Even more striking in some cases are the changes in diffusionweighted imaging sequences (DWI) Long segments of the cortex as well as various parts of the basal ganglia show these alterations in a pattern that, in our experience, is characteristic and mistakable only perhaps for the appearance of diffuse cerebral anoxia (Fig 335B) According to Shiga and colleagues, these changes occur in 90 percent of cases (cortex more often than caudate or lenticular nuclei and sometimes both), making them potentially the most sensitive test for the disease There are now helpful con rmatory diagnostic tests but they are often unnecessary Hsich and colleagues have described a sensitive test of CSF the nding by immunoassay of a particular peptide fragments of normal brain proteins, termed 14-3-3, This test is particularly useful in separating SSE from other chronic nonin ammatory dementing diseases, but it has been disappointing on our wards, giving both false-positive and false-negative results A number of other tests are emerging from specialized laboratories that detect the abnormal PrPSc isoform of the prion protein in the spinal uid Prusiner s laboratory can detect eight prion strains by uorescence immunoassay Also, enolase and neopterin concentrations in CSF are elevated in most cases, but the release of these substances may also be found with other types of brain lesions, particularly infarction.
