  • Parkinson's disease is one of the most frequent neurodegenerative diseases, which mainly affects the elderly. Parkinson's disease is often difficult to differentiate from atypical parkinson diorder such as progressive supranuclear palsy, multiple system atrophy, dementia with Lewy body, and corticobasal ganglionic degeneration, based on the clinical findings because of the similarity of phenotypes and lack of diagnostic markers. The accurate diagnosis of Parkinson's disease and atypical Parkinson disorders is not only important for deciding on treatment regimens and providing prognosis, but also it is critical for studies designed to investigate etiology and pathogenesis of parkinsonism and to develop new therapeutic strategies. Although degeneration of the nigrostriatal dopamine system results in marked loss of striatal dopamine content in most of the diseases causing parkinsonism, pathologic studies revealed different topographies of the neuronal cell loss in Parkisonism. Since the regional cerebral glucose metabolism is a marker of integrated local synaptic activity and as such is sensitive to both direct neuronal/synaptic damage and secondary functional disruption at synapses distant from the primary site of pathology, an assessment of the regional cerebral glucose metabolism with F-18 FDG PET is useful in the differential diagnosis of parkinsonism and evaluating the pathophysiology of parkisonism.

  • Parkinson's disease (PD) is clinically characterized by a variety of motor and non-motor symptoms, including cognitive and neuropsychiatric symptoms. Integrating a large variety of symptoms into a small number of clinical subtypes could be valuable for appropriate and early therapeutic intervention. As a first step toward this aim, this study attempted to identify correlation patterns among motor, cognitive and neuropsychiatric symptoms in PD without dementia. One hundred four non-demented patients with PD underwent a comprehensive motor, neuropsychological, and neuropsychiatric assessments. Factor analysis was performed to identify correlation patterns among demographic, motor, cognitive and neuropsychiatric variables. The eight factors were extracted: 1 motor-related, 3 cognitive-related and 4 neuropsychiatric factors. We indentified that characteristics of correlation can have associated symptom pattern in the disease process of Parkinson's disease. The current results suggest that a broad range of motor and non-motor symptoms in PD may be reducible to a small number of clinical parameters, which may be useful for identifying clinical subtypes of PD for individual patients.

  • Dementia with Lewy bodies (DLB) is the second most common causes of dementia. It can exhibit a variety of clinical symptoms including cognitive decline, cognitive fluctuation, visual hallucinations, parkinsonism, REM sleep behavior disorder, hypersensitivity to neuroleptics and autonomic dysfunctions. Despite more well-known criteria for DLB, there are often misdiagnosis and inappropriate treatment. It gives a lot of clinical burden to the clinician as well as to patients and families. When reducing the misdiagnosis, the burden of all will be reduced. The special concern and solicitation are needed in order not to miss the diagnosis when the cardinal features of DLB may not be volunteered by patients and the caregivers. To control the symptoms, clinicians must find and reduce drugs that can have the negative effects on DLB symptoms. There is limited evidence about specific interventions but available data suggest cholinesterase inhibitors improve the cognitive and behavioral symptoms and menmantine slightly improves the global impression.

  • Purpose: The aim of this study was to evaluate the discriminating nature of $^{123}I-FP-CIT$ SPECT in patients with parkinsonism. Methods: $^{123}I-FP-CIT$ SPECT images acquired from the 18 normal controls; NC ($60.4{\pm}10.0$ yr) and 237 patients with parkinsonism ($65.9{\pm}9.2$ yr) were analyzed. From spatialIy normalized images, regional counts of the caudate, putamen, and occipital lobe were obtained using region of interest method. Binding potential (BP) was calculated with the ratio of specific to nonspecific binding activity at equilibrium. Additionally, the BP ratio of putamen to caudate (PCR) and asymmetric Index (ASI) were measured. Results: BPs of NC $3.37{\pm}0.57,\; 3.10{\pm}0.41,\; 3.23{\pm}0.48$ for caudate, putamen, whole striatum, respectively) had no significant difference with those of essential tremor; ET ($3.31{\pm}0.64,\; 3.06{\pm}0.61,\; 3.14{\pm}0.63$) and Alzheimer's disease; AD (3.33 $\pm$0.60, 3.29$\pm$0.79, 3.31$\pm$0.70), but were higher than those of Parkinson's disease; PD (1.92$\pm$0.74, 1.39$\pm$0.68, 1.64$\pm$0.68), multiple system atrophy; MSA (2.36$\pm$1.07, 2.16$\pm$0.91, 2.26$\pm$0.96), and dementia with Lewy body; DLB (1.95$\pm$0.72, 1.64$\pm$0.65, 1.79$\pm$0.66)(p<0.005). PD had statisticalIy lower values of PER and higher values of ASI than those of NC (p<0.005). And PD had significantIy lower value of PCR, higher ASI and lower BP in the putamen and whole striatum than MSA (p<0.05). Conclusion: Dopamine transporter image of $^{123}I-FP-CIT$ SPECT was a good value in differential diagnosis of parkinsonism.

  • Purpose: The purpose of this paper is to provide nurses with a concise review on neurodegenrative dementias. This review includes pathophysiology, clinical course, and tips on management of dementias from Alzheimer's disease (AD), Parkinson disease (PD) and lewy body dementia (LBD). Considering increasing numbers of dementia cases among older adults, nurses who are cognizant about dementia care are instrumental in maximizing daily activities and quality of life of patients with cognitive impairment and dementia.

  • Anumber of prior studies have reported eye movement dysfunction in patients with dementia. The eye movement test which is non-invasive can evaluate the local brain function quantitatively. Therefore, it can be a useful method for characterizing regional brain abnormalities of patients with dementia. The aim of this paper is to review the literatures on eye movement abnormalities in dementia patients. Saccade system dysfunctions in Alzheimer disease include increased latency, reduced accuracy, and increased antisaccade error rates. Patients with frontotemporal dementia showed impaired reflexive saccade inhibition and increased latency and errors of antisaccade task. And delayed initiation of voluntary saccades, slow saccades, and increased errors and latency on antisaccade task were found in Huntington's disease. Patients with Parkinson’s disease dementia and dementia with Lewy bodies have characteristics of impaired in both reflexive saccade execution and complex saccade performance. However, there were few reports of abnormal eye movements in Creutzfeldt-Jakob disease; they could be found at the later stages after symptoms of dementia came to be evident, and secondary to cerebellar and vestibular involvement. Slowing of saccades and hypometric saccades might precede the supranuclear limitation of vertical gaze in PSP. Dysfunction of voluntary eyelid movements was a characteristic finding of PSP as well. In conclusion, patients with dementia can show various abnormal eye movements and they are related with cortial and subcortical brain dysfunctions. The research on localization of brain relevant to each symptom can promise more clinical implications of eye movement of dementia.

  • Sleep disturbances are frequently associated with neurological disorders. Sleep disorders interfere with rehabilitation of patients with neurological disorders such as stroke and may increase the severity of their symptoms and recurrence rate of stroke. The treatment of sleep apnea syndrome is particularly important in managing patients with cerebral infarction of whom 50-80% have moderate to severe sleep apnea. Sleep apnea produces not only poor quality sleep but also excessive daytime sleepiness, fatigue and lack of energy. Sleep problems frequently found in patients with dementia are sleep-wake cycle abnormality, fragmentation of sleep, nocturnal insomnia, decreased slow wave sleep and REM sleep, and sleep disordered breathing. The management of sleep disturbances is very important for controlling symptoms such as nocturnal wandering and sundowning syndrome in patients with dementia. Parkinson's disease and epilepsy are other neurological disorders that may have sleep disturbances.
