This case report describes the sporadic Creutzfeldt-Jakob disease (CJD) of a 53-year-old man who initially complained about vertigo and dizziness. Within 18 weeks, he developed impaired memory, hemineglect, and sensory impairment of the left half of the body. A CSF tap was positive for 14-3-3 protein and showed increased tau protein, neuron-specific enolase (NSE), and the astroglial protein S-100 B. The EEG showed right temporal sharp waves without periodicity. Diffusion-weighted MRI revealed hyperintensities in the right temporo-occipital cortex which corresponded well with hypometabolic areas in a PET scan and the neurological and neuropsychological deficits. The morphological FLAIR T2 MRI showed no pathological changes. Within 20 weeks, the patient developed severe dementia with decreased spatial orientation and myoclonia, became incontinent, and was confined to bed. He died within 22 weeks after the first presentation of symptoms.

A case of Creutzfeldt-Jakob disease (CJD) with a rare mutation of the prion protein (PrP) gene (PRNP) at codon 208 (R208H), while the codon 129 was a methionine homozygous genotype is reported. The patient initial displayed hand tremor, dizziness and progressive cognitive dysfunction. Subsequently, other symptoms gradually appeared, including cerebellar ataxia and mental disorder. No periodic activity was recorded at electroencephalography (EEG) and 14-3-3 protein in cerebrospinal fluid was negative. Total clinical course was about 4 months. Retrospective investigation of this family across seven generations did not figure out clear family history. However, genetic analyses revealed six first-degree family members with the R208H allele.

Here, we report a Chinese case of Creutzfeldt-Jakob disease (CJD) with a rare mutation in the prion protein gene (PRNP) leading to an exchange of amino acid from valine (Val) to isoleucine (I) at codon 203 (V203I). The 80-y-old male presented with sudden memory loss, rapid loss of vocabulary, inattention and slow responses, accompanied by dizziness, blurred vision and ataxia. Two weeks after admission, he exhibited tremor, myoclonus and bilateral Babinski signs. At the end of the clinical course, he developed severe akinetic mutism. The cerebrospinal fluid (CSF) was positive for 14-3-3 protein. Increased bilateral signal intensity in the frontal and parietal lobes was seen on diffusion-weighted imaging (DWI); periodic activity was recorded on an electroencephalogram (EEG). There was no family history of similar symptoms. The total clinical course was approximately two months.

Sporadic Creutzfeldt-Jakob disease (CJD) is clinically characterized by rapidly progressive dementia combined with other cardinal symptoms, such as myoclonus, visual or cerebellar disturbances, extrapyramidal or pyramidal disturbance, and akinetic mutism. However, as an initial manifestation, focal neurologic deficits other than the aforementioned or nonspecific generalized symptoms may lead to a misdiagnosis or a delayed diagnosis. The authors report a case of 66-year-old male patient with sporadic CJD who had dizziness, gaze-evoked nystagmus (GEN), and other central eye signs (impaired smooth pursuit, saccadic dysmetria) as an initial manifestation without dementia. The central eye signs led us to perform brain magnetic resonance images, which showed abnormal cortical high-signal intensity in both the cerebral and cerebellar hemispheres including the vestibulocerebellum. We reached a presumptive diagnosis of CJD, but the findings did not meet diagnostic criteria for probable CJD at that time. Three weeks after the initial work-ups, the patient presented with typical neurological findings of CJD: rapidly progressive dementia, akinetic mutism, and myoclonus of the left arm. Cerebrospinal fluid was positive for 14-3-3 protein, and electroencephalography showed periodic sharp wave complexes. In this patient, GEN and other central eye signs provided diagnostic clues for CJD. These unusual neurological manifestations may help physicians have a thorough knowledge of early deficits of CJD.

We reported the case of a patient with Wernicke-Korsakoff syndrome (WKs) as an early clinical manifestation of sporadic Creutzfeld-Jakob disease (sCJD). The 66-year-old female complained of dizziness and imbalance which mostly occurred while walking. A neurological examination revealed a triad of symptoms characteristic for WKs such as gaze paresis, ataxia of limbs and trunk as well as memory disturbances with confabulations. The disturbances increased during the course of the disease, which led to the death of the patient four months after the appearance of the signs. The patient was finally diagnosed with sCJD disease. The most useful ancillary examination results supporting sCJD diagnosis were brain diffusion DWI MRI (diffusion weighted magnetic resonance imaging) and the presence of 14-3-3 protein in CSF (cerebrospinal fluid). Since that manifestation of sCJD is very unique other causes should be taken into consideration while making a final diagnosis.

Creutzfeldt-Jakob disease (CJD), also known as corticostriate spinal degeneration, subacute spongiform encephalopathy or infectious spongiform encephalopathy, is a type of degenerative disease of the central nervous system caused by prion protein (PrP) infection, which is the most common type of human PrP disease. CJD is genetic and infectious, and is one of the most common causes of rapid progressive dementia with rare clinical occurrence. Herein, we report the clinical conditions of 2 cases of patients with different type of CJD we treated and followed up recently, and a review of relevant literature. The patient in case 1 was admitted due to 'dizziness with hypomnesis, and mental and behavior disorder'. He was considered to suffer from a central nervous system infection - a viral encephalitis, but one month later, a repeated cranial MRI showed lace sign of bilateral frontotemporal parietal lobe in DWI sequence, an AEEG indicated periodic synchronous discharge, and the detection of cerebrospinal fluid 14-3-3 protein was positive. It was suggested to be diagnosed as the sporadic CJD. The patient in case 2 was admitted because of 'progressive hypomnesis'. Cerebrospinal fluid 14-3-3 protein detection was negative, but the V203I-related mutation was found in the PRNP gene detection. The patient was suggested to be diagnosed as genetic CJD. Both patients died in a short time. An earlier diagnosis can provide a time window for treatment, and avoid unnecessary transmission in hospital, as well as doctor-patient dispute.
