Behavioral symptoms are well-recognized concomitants of the progression of dementia. These symptoms include agitation, aggression, anxiety, depression, disinhibition, delusions, hallucination, and sleep disturbance. Because these symptoms are a major source of impaired quality of life for patients and their caregivers, appropriate pharmacological management of them may reduce the burden of caregivers and postpone institutionalization. Furthermore, behavioral symptoms may be more amenable to pharmacological intervention than cognitive symptoms. For that reason, detailed evaluation and appropriate treatment are the mainstay in the management of dementia patients. In this article, we reviewed symptomatology and psychopharmacology for behavioral symptoms of dementia.

BACKGROUND: The conventional electroencephalography (EEG) is commonly used as an aid in the diagnosis of Alzhiemer's disease (AD). Recently developed quantitative electroencephalography (qEEG) provides data that are not achievable by conventional EEG. Nevertheless, the clinical reliability and usefulness of spectral analysis and topographic mapping is still a matter of controversy in the diagnosis of Alzheimer's disease. The aim of this study was to compare the topographical quantitative EEG (qEEG) changes between elderly controls and AD patients. METHODS: We analyzed the absolute, relative spectra power and occipital peak frequency taken from 16 derivations by averaging twenty-2-sec epoch in elderly controls and AD patients. After logarithmic transformations of absolute and relative power, a statistical test was done and occipital peak frequency was compared with each other. RESULTS: (1) Compared with normal controls, AD patients had a significantly lower alpha and beta spectra power as well as a significant higher delta spectra power. (2) In AD patients, the peak frequency in occipital lead had a significantly lower frequency than that of elderly controls. (3) Korean Mini-Mental State Examination(K-MMSE) scores were closely related in delta and alpha band power in nearly all electric leads. (4) Compared to absolute power, relative power was a more sensitive tools in detecting changes of EEG in AD patients. CONCLUSIONS: This study suggests that qEEG is a useful tool for detecting the electroencephalographic changes of AD, and correlated with the severity of cognitive dysfunction. Moreover, absolute and relative spectra power is complementary in the clinical utility of qEEG.

BACKGROUND: Neuropsychological Differentiation between Alzheimer's disease and vascular dementia has been controversial. The aim of this study was to detect neuropsychological differences between Alzheimer's disease (AD) and vascular dementia (VD). METHODS: Twenty one patients who met the criteria for probable AD according to the National Institute of Neurological Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) and 22 patients who met criteria for probable VD according to the National Institute of Neurological Disorders and Stroke and the Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS-AIREN), were included in this study. These two dementia groups were matched for age, sex, education, Mini-Mental State Examination score, and severities of dementia. All patients underwent the Seoul Neuropsychological Screening Battery (SNSB). RESULTS: Patients with VD showed greater deficits in verbal fluency (P<.05) than AD patients. However, AD patients, compared with VD patients, showed greater deficits in verbal memory functions including the 3 words recall task. Otherwise, no significant between-group differences were found in task results. CONCLUSIONS: Neuropsychologically, patients with VD differ from patients with AD only in a few cognitive domains.

The July issue of Clinical Endoscopy deals with selected articles covering the state-of-the-art lectures delivered during the 50th seminar of the Korean Society of Gastrointestinal Endoscopy (KSGE) on March 30, 2014, highlighting educational contents pertaining to either diagnostic or therapeutic gastrointestinal (GI) endoscopy, which contain fundamental and essential points in GI endoscopy. KSGE is very proud of its seminar, which has been presented twice a year for the last 25 years, and hosted more than 3,500 participants at the current meeting. KSGE seminar is positioned as one of premier state-of-the-art seminars for endoscopy, covering topics for novice endoscopists and advanced experts, as well as diagnostic and therapeutic endoscopy. The 50th KSGE seminar consists of more than 20 sessions, including a single special lecture, concurrent sessions for GI endoscopy nurses, and sessions exploring new technologies. Nine articles were selected from these prestigious lectures, and invited for publication in this special issue. This introductory review, prepared by the editors of Clinical Endoscopy, highlights core contents divided into four sessions: upper GI tract, lower GI tract, pancreatobiliary system, and other specialized topic sessions, including live demonstrations and hands-on courses.

In recent days quantitative electroencephalography (QEEG) has grown rapidly and QEEG techniques and EEG mapping have shown localizing functional imaging. We report two cases of falsely lateralized EEG mapping in stroke patients. Both cases had right hemispheric stroke, but presented bilateral clinical symptoms. Contrary to structural imaging, EEG mapping displayed left hemispheric dysfunction and SPECT displayed bilateral perfusion Aegects. These findings suggest that false lateralization of EEG mapping in unilateral stroke patients may show bilateral cerebral dysfunction not detected in conventional imaging technique.

Rapid advances in the technology of gastrointestinal endoscopy as well as the evolution of science have made it necessary for us to continue update in either various endoscopic techniques or state of art lectures relevant to endoscopy. International Digestive Endoscopy Network (IDEN) 2013 was held in conjunction with Korea-Japan Joint Symposium on Gastrointestinal Endoscopy (KJSGE) during June 8 to 9, 2013 at Seoul, Korea. Two days of impressive scientific program dealt with a wide variety of basic concerns from upper gastrointestine (GI), lower GI, pancreaticobiliary endoscopy to advanced knowledge including endoscopic submucosal dissection forum. IDEN seems to be an excellent opportunity to exchange advanced information of the latest issues on endoscopy with experts from around the world. In this special issue of Clinical Endoscopy, we prepared state of art review articles from contributing authors and the current highlights will skillfully deal with very hot spots of each KJSGE, upper GI, lower GI, and pancreaticobiliary sessions by associated editors of Clinical Endoscopy.
