Abstract
Key Clinical Message Creutzfeldt-Jakob disease is a neurodegenerative disorder caused by brain accumulation of a misfolded form of the cellular prion protein, whose diagnosis is challenging, particularly in early stages, due to the variability and nonspecificity of the clinical and radiological features. 18F-fluorodeoxyglucose positron-emitted tomography has the potential to be considered a crucial investigation in these patients, revealing metabolic abnormalities earlier than the conventional neuroimaging analysis. Abstract A 59-year-old man, the military officer, was referred to our Units for the onset of neurological symptoms rapidly evolving within a month, characterized by akinetic mutism, constructional apraxia, and disorders of spatial orientation. Brain 18F-fluorodeoxyglucose (18F-FDG) positron-emitted tomography (PET)/CT depicted an asymmetric hypometabolism in the left fronto-temporo-parietal cortex, as well as in the left thalamus and the right cerebellar hemisphere, while the glucose metabolism appears to be preserved in the somatosensory cortex and the basal ganglia. Laboratory routine analyses, cerebrospinal fluid routine, infective tests, electroencephalography (EEG), and brain magnetic resonance (MR) were all unremarkable. A positive RT-QuIC result on cerebro-spinal fluid (CSF) was subsequently shown, without any pathogenic gene mutations and, therefore, the result was consistent with a diagnosis of sporadic Creutzfeld-Jacob disease. The clinical evolution was quickly unfavorable, and the patient died about 4 months after hospital admission. FDG PET/computed tomography (CT) has the potential to be considered a crucial investigation in these patients, documenting metabolic changes long time before other diagnostic investigations such as CSF, EEG, brain CT, and brain MR, thus suggesting a greater sensitivity of glucose metabolic evaluation in the early stage of the disease in question.

Abstract
Prion diseases are rare, rapidly progressive, and fatal incurable degenerative brain disorders caused by the misfolding of a normal protein called PrPC into an abnormal protein called PrPSc. Their highly variable clinical presentation mimics various degenerative and non-degenerative brain disorders, making diagnosis a significant challenge for neurologists. Currently, definitive diagnosis relies on post-mortem examination of nervous tissue to detect the pathogenic prion protein. The current diagnostic criteria are limited. While structural magnetic resonance imaging (MRI) remains the gold standard imaging modality for Creutzfeldt-Jakob disease (CJD) diagnosis, positron emission tomography (PET) using 18fluorine-fluorodeoxyglucose (18F-FDG) and other radiotracers have demonstrated promising potential in the diagnostic assessment of prion disease. In this context, a comprehensive and updated review exclusively focused on PET imaging in prion diseases is still lacking. We review the current value of PET imaging with 18F-FDG and non-FDG tracers in the diagnostic management of prion diseases. From the collected data, 18F-FDG PET mainly reveals cortical and subcortical hypometabolic areas in prion disease, although fails to identify typical pattern or laterality abnormalities to differentiate between genetic and sporadic prion diseases. Although the rarity of prion diseases limits the establishment of a definitive hypometabolism pattern, this review reveals some more prevalent 18F-FDG patterns associated with each disease subtype. Interestingly, in both sporadic and genetic prion diseases, the hippocampus does not show significant glucose metabolism alterations, appearing as a useful sign in the differential diagnosis with other neurodegenerative disease. In genetic prion disease forms, PET abnormality precedes clinical manifestation. Discordant diagnostic value for amyloid tracers among different prion disease subtypes was observed, needing further investigation. PET has emerged as a potential valuable tool in the diagnostic armamentarium for CJD. Its ability to visualize functional and metabolic brain changes provides complementary information to structural MRI, aiding in the early detection and confirmation of CJD.

Abstract
ABSTRACT Early diagnosis of Creutzfeldt-Jakob disease (CJD) patients is often challenging due to the low sensitivity of the current clinical diagnostic criteria. We describe MRI and dual-phase 18 F-FP-CIT PET findings in 2 cases of sporadic CJD presenting different clinical phenotypes (Heidenhain variant and corticobasal syndrome). Our case series suggest that dual-phase FP-CIT-PET findings may improve the diagnosis of CJD by combining the perfusion patterns in early phase with the dopamine transporter density in delayed phase. Familiarity with these dual-phase FP-CIT PET findings is helpful for early correct diagnosis of CJD.

Abstract
Corticobasal syndrome is a disorder of movement, cognition and behaviour with several possible underlying pathologies, including corticobasal degeneration. It presents insidiously and is slowly progressive. Clinicians should consider the diagnosis in people presenting with any combination of extrapyramidal features (with poor response to levodopa), apraxia or other parietal signs, aphasia and alien-limb phenomena. Neuroimaging showing asymmetrical perirolandic cortical changes supports the diagnosis, while advanced neuroimaging may give insight into the underlying pathology. Identifying corticobasal syndrome carries some management implications (especially if protein-based treatments arise in the future) and prognostic significance. Its treatment is largely symptomatic and is best undertaken within a multidisciplinary setting, including a neurologist, physiotherapist, occupational therapist, speech language therapist, psychiatrist and, ultimately, a palliative care clinician. Corticobasal syndrome can be a confusing entity for neurologists, not least because it has over time evolved from being considered predominantly as a movement disorder to a condition spanning a wide range of cognitive and motor manifestations. In this practical review, we attempt to disentangle this syndrome and provide clarity around diagnosis, its underlying pathological substrates, key clinical features and potential treatments.

Abstract
The spectrum of tauopathy encompasses heterogenous group of neurodegenerative disorders characterized by neural or glial deposition of pathological protein tau. Clinically they can present as cognitive syndromes, movement disorders, motor neuron disease, or mixed. The heterogeneity in clinical presentation, genetic background, and underlying pathology make it difficult to classify and clinically approach tauopathy. In the literature, tauopathies are thus mostly highlighted from pathological perspective. From clinical standpoint, cognitive syndromes are often been focussed while reviewing tauopathies. However, the spectrum of tauopathy has also evolved significantly in the domain of movement disorders and has transgressed beyond the domain of primary tauopathies. Secondary tauopathies from neuroinflammation or autoimmune insults and some other "novel" tauopathies are increasingly being reported in the current literature, while some of them are geographically isolated. Because of the overlapping clinical phenotypes, it often becomes difficult for the clinician to diagnose them clinically and have to wait for the pathological confirmation by autopsy. However, each of these tauopathies has some clinical and radiological signatures those can help in clinical diagnosis and targeted genetic testing. In this review, we have exposed the heterogeneity of tauopathy from a movement disorder perspective and have provided a clinical approach to diagnose them ante mortem before confirmatory autopsy. Additionally, phenotypic variability of these disorders (chameleons) and the look-alikes (mimics) have been discussed with potential clinical pointers for each of them. The review provides a framework within which new and as yet undiscovered entities can be classified in the future.

Abstract
We report the case of a 64-year-old man referred for optic ataxia, constructional apraxia, and spatial orientation disorders evolving for 2 months. Benson syndrome (posterior cortical atrophy) was initially suspected. Brain F-FDG PET/CT depicted an asymmetric decreased uptake pattern consistent with Creutzfeldt-Jakob disease. 14-3-3 proteins were detected in the cerebrospinal fluid. Clinical evolution was quickly unfavorable. The patient died 1 month after the PET/CT, and Creutzfeldt-Jakob disease was confirmed on postmortem examination of brain tissue.

Abstract
The introduction of prion RT-QuIC, an ultrasensitive specific assay for the in vivo detection of the abnormal prion protein, has significantly increased the potential for an early and accurate clinical diagnosis of Creutzfeldt-Jakob disease (CJD). However, in the clinical setting, the early identification of patients with possible CJD is often challenging. Indeed, CJD patients may present with isolated symptoms that remain the only clinical manifestation for some time, or with neurological syndromes atypical for CJD. To enhance awareness of unusual disease presentations and promote earlier diagnosis, we reviewed the entire spectrum of atypical early manifestations of CJD, mainly reported to date as case descriptions or small case series. They included sensory either visual or auditory disturbances, seizures, isolated psychiatric manifestations, atypical parkinsonian syndromes (corticobasal syndrome, progressive supranuclear palsy-like), pseudobulbar syndrome, isolated involuntary movements (dystonia, myoclonus, chorea, blepharospasm), acute or subacute onsets mimicking a stroke, isolated aphasia, and neuropathy. Since CJD is a rare disease and its clinical course rapidly progressive, an in-depth understanding and awareness of early clinical features are mandatory to enhance the overall diagnostic accuracy in its very early stages and to recruit optimal candidates for future therapeutic trials.

Abstract
Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare neurodegenerative disease that can mimic other neurological disorders. We present a case of sCJD in a 64-year-old man that presented with corticobasal syndrome and survived for 3 years. He presented initially with dementia, hemiparkinsonism and alien limb phenomenon and was diagnosed with corticobasal degeneration, ultimately progressing to immobility and akinetic mutism. With a normal MRI 1 year before onset, his neuroimaging 1 year later revealed abnormal DaTscan, cortical and hippocampal atrophy with ventricular dilatation on MRI, and diffusion-weighted cortical ribboning and thalamic hyperintensity. Postmortem, the patient's brain was collected by the Parkinson's UK Tissue Bank. Prion protein immunohistochemistry revealed widespread diffuse microvacuolar staining without kuru-type plaques. Hyperphosphorylated tau was only found in the entorhinal cortex and hippocampus. This case highlights the clinical heterogeneity of sCJD presentation and the important inclusion of CJD in the differential diagnosis of atypical presentations of neurodegenerative disease.

Abstract
Sporadic Creutzfeldt-Jakob disease (sCJD) is a fatal progressive neurodegenerative disease. Multimodal approaches, including electroencephalogram, diffusion-weighted imaging (DWI) of brain MRI, and cerebrospinal fluid biomarkers, have been applied to increase the diagnostic accuracy of sCJD. Although previous studies suggested DWI could be the most useful modality for sCJD diagnosis, whether metabolism changes underlying in sCJD are still poorly understood. To the best of our knowledge, there are only one case using the technique of arterial spin labeling (ASL) to detection and follow-up of perfusion changes in CJD. Herein, we described a 71-year-old woman presented with progressive cognitive decline, behavioral and psychological symptoms for two months. The patient died one month later after her admission. As far as we know, this is the first report using the combination of fluorodeoxyglucose positron emission tomography and ASL to explore the metabolism changes in sCJD. Our case exemplifies the difficulty clinicians may face in the diagnosis of sCJD.

Abstract
A 78-year-old man received a diagnosis of sporadic Creutzfeldt-Jakob disease based on symptoms and findings of MRI, FDG PET, and cerebrospinal fluid markers. PET with 3-dimensional stereotactic surface projection (3D-SSP) showed that the distribution of hypometabolism mimicked that of Alzheimer disease. A 68-year-old woman was treated under a diagnosis of convulsion. Findings of MRI, PET, familial history, and cerebrospinal fluid markers revealed familial Creutzfeldt-Jakob disease. FDG PET with 3D-SSP disclosed that the hypometabolic pattern mimicked that of dementia with Lewy bodies. FDG PET with 3D-SSP can demonstrate similar patterns in various neurodegenerative disorders.

Abstract
Atypical parkinsonism syndromes, such as dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy and corticobasal degeneration, are neurodegenerative diseases with complex clinical and pathological features. Heterogeneity in clinical presentations, possible secondary determinants as well as mimic syndromes pose a major challenge to accurately diagnose patients suffering from these devastating conditions. Over the last two decades, significant advancements in genomic technologies have provided us with increasing insights into the molecular pathogenesis of atypical parkinsonism and their intriguing relationships to related neurodegenerative diseases, fueling new hopes to incorporate molecular knowledge into our diagnostic, prognostic and therapeutic approaches towards managing these conditions. In this review article, we summarize the current understanding of genetic mechanisms implicated in atypical parkinsonism syndromes. We further highlight mimic syndromes relevant to differential considerations and possible future directions.

Abstract
Here, we present a patient with Creutzfeldt-Jakob disease (CJD) who developed initial symptoms mimicking progressive supranuclear palsy (PSP). Before the development of typical CJD symptoms, functional imaging supported a diagnosis of PSP when [(123)I]-FP-CIT-SPECT showed a defect in striatal dopamine transporter binding, while [(18)F]-fluorodeoxyglucose PET showed cortical hypometabolism suggestive of Lewy body dementia. However, the postmortem neuropathological examination was indicative of CJD only, without tau protein or Lewy body findings. This case demonstrates that CJD should be taken into account in rapidly progressing atypical cases of parkinsonism, even when functional imaging supports a diagnosis of a movement disorder.
