2017 Sistemi Evoluti per Basi di Dati  
Electroencephalography (EEG) is one of the main methods to perform clinical diagnosis of CJD, mainly because of Periodic Sharp Wave Complexes (PSWCs).  ...  Furthermore, network motifs are able to detect what the most active and/or connected brain areas are in the tracing segments with PSWCs.  ...  In fact, in the EEG of patients with sCJD, it is often possible to observe three-phase periodic spikes with sharp waves known as "Periodic Sharp Wave Complexes" (hereafter, PSWCs).  ...

Due to low rate of brain autopsy in China, performances of other CJD-associated examinations as much as possible are extremely important for the distinguish diagnosis of young probable sCJD patients.  ...  Special sCJD-associated abnormalities on EEG and MRI were noticed in 7 and 10 cases. CSF 14-3-3 was positive in 7 cases. CSF RT-QuIC showed positive reactive curves in 9 cases, with short lag phases.  ...  As shown in Fig. 2B , periodic sharp wave complexes (PSWC) were noted in 7 (58.33%) patients out of 12 who received EEG examinations. sCJD-associated abnormalities (high signal abnormalities in caudate  ...
