  • 1. Out of 21 examples on a clinical base Alzheimer type dementia were 8 examples(38%), 11 vascular types(52%), 1 Alzheimer and vascular mixed type and rest 1 was secondary dementia type(NPH).2. Between the genders, there were 5 males and 3 females for Alzheimer types, 6 males and 5 females for the vascular types, 1 male for Alzheimer and vascular mixed type, and 1 female for secondary dementia type(NPH).3. For the degrees of Alzheimer type dementia there were 2 mild dementia, 4 moderate dementia, and 2 severe dementia. 4. Among the Alzheimer types 2 mild dementia were almost recovered back to normal in approximately 2 months, 2of 4 moderate dementia became significantly better in approximately 2 months and recovered to almost normal state in 3 to 5 months. The rest 2 have been under treatment for 3 months, but showed a little improvement. Out of 2 severe dementia examples, one showed a little improvement even if it has been under treatment over 2 years. The other example did not show any improvement, but dementia did not proceed any more.5. Among the 11 vascular examples, 7 recovered in 2 to 3 months, 1 in 5 months, 2 recovered in a year, and the treatment was stopped arbitrary for the last one.6 In the case of Alzheimer and vascular mixed type dementia, even the moderate dementia did not show any apparent result in 6 months.7. For NPHI (Normal Pressure Hydrocephalus), there was an improvement on dementia in 2 months after the treatment, but gait disturbance and urinary incontinence did not show any noticeable difference. As a conclusion, almost all the Alzheimer and vascular type patients recovered, but the treatment periods varied depending on the types of the dementia and the degree of seriousness, especially in the case of the severe Alzheimer patients, the treatment oniy suppression the progression of the dementia. The most important aspect from clinical point of view was even if almost all the patients were almost completely cired, they need to keep being cured for a long period of time. The method with respect to Four Constitutions is thought of the most desirable.

  • Objectives : The purpose of this study was to find brain regions in which gray matter volume was reduced and to show the capability of voxel-based morphpmetry(VBM) analysis for lateralizing clinically significant brain regions in dementia of Alzheimer's type patients compared to healthy group. Methods : MR T1-weighted images of the 20 dementia of Alzheimer's type patients were compared with those of the 20 normal controls. Images were transformed to standard MNI space. In order to observe gray matter volume change. Gray matter was smoothed with a Gaussian kernel. After these preprocessing, statistical analysis was performed using statistical parametric mapping software(SPM2). Results : Gray matter volume was significantly reduced in the bilateral parahippocampal gyri, Lt. anterior cingulate gyrus, Lt. posterior cingulate gyrus, bilateral superior temporal gyri Lt. middle temporal gyrus, Lt. superior, bilateral middle, Rt. anterior frontal gyri and Rt. precuneus in dementia of Alzheimer's type patient group. Conclusions : These VBM results confirm previous findings of temporal lobe and limbic lobe atrophic changes in dementia of Alzheimer's type, and suggest that these abnormalities may be confined to specific sites within that lobe, rather than showing a widespread distribution.

  • This study attempted to analyze the contents of the research papers concerning the diagnosis and treatment of Alzheimer-type dementia presented in the magazine of Chinese Medicine published in China over the period between 1998 and 2000. As a result, the following conclusion was drawn: 1. The Chinese medical category of Alzheimer-type dementia includes amnesia, dementia, stupidity, depression symptom complex, insanity and the like and uses the as the criterion for diagnosis and treatment effect evaluation. 2. The clinical symptoms of Alzheimer-type dementia include lowered intelligence, deterioration of memory, understanding and judgemental power, retardation of the reaction, emotional changes, character changes, behavioral changes and the like and are divided into mild, medium and serious according to the degree of symptom. 3. From the perspective of Bon-Heo-Pyo-Shil(state of deficient vital essence and excessive pestilential vapor), the pattern of Byun-Sung(identification) is divided into deficiency symptom complex, excessive symptom complex and indiscernible fullness and emptiness. The deficiency symptom complex includes deficiency of the liver and kidney, deficiency of essence of the kidney, deficiency of the reservoir of marrow and the like. The excessive symptom complex includes internally blocked stagnant blood, blocking of the passageway due to turbid phlegm, blood stasis due to stagnation of chi, and the like. The indiscernible fullness and emptiness symptom complex includes the deficiency of essence of kidney, blocking of the passageway due to stagnant phlegm, blood stasis due to the deficiency of kidney, blood stasis due to the deficiency of heart and the like. 4. The therapeutics and' prescription of Alzheimer-type dementia include the following: Bo-Shin-Ik-Su-Tang for tonifying the kidney, replenishing the marrow and plugging the essence; Ki-Guk-Ji-Hwang-Hwan-Ga-mi for reinforcing the vital essence of the liver and kidney; Kwi-Bi-Tang-Hap-Yang-Shim-Tang for invigorating the functioning of the spleen and nourishing the heart; Hyel-Bu-Chuk-Eo-Tang-Ga-Mi for activating the blood and resolving the stagnancy of the blood; Bo-Yang-Hwan-Oh-Tang for replenishing chi, activating the blood and resolving the stagnancy of the blood; Beoh-Kwang-Mong-Sung-Tang for invigorating the functioning of the spleen, replenishing the kidney, resolving the phlegm and enlivening the brain; n-Dam-Tang-Ga-Mi for invigorating the functioning of the spleen, replenishing chi, and removing the phlegm and unclogging the passageway); Se-Shim-Tang-Ga-Mi for removing the stagnancy of the liver and resolving the phlegm; and the like. 5. The research papers on, the medication cases of Alzheimer-type dementia understand the pathology of Alzheimer-type dementia from a consistent perspective. They view the pathology of Alzheimer-type dementia as the disease of Bon-Heo-Pyo-Shil(state of deficient vital essence and excessive pestilential vapor) with the combination of the deficiency of essence of the kidney, the deficiency of the brain marrow, blood stasis and blocked phlegm and the like and recommend the prescription of using Bo and Sa simultaneously for treating Alzheimer-type dementia. 6. The research papers on the medication cases of Alzheimer-type dementia reported that the use of creative prescriptions such as Si-Sam-Hang-Ji-Tang, Ji-Yung-Tang, Ka-Mi-Yunh-Ji-Hwan, Ja-Sin-Hwal-Hyel-Tang, Kal-Chang-Ik-Ji-Tang, Ho-Su-Bok-Ji-Tang, Kun-Noe-Ok-Ji-Hap-Je and the like led to the average high efficacy of 85.5%.

  • This study is to develop the Alzheimers disease (AD) detection and analysis system using event-related potential (ERP) of AD patients. We recorded ERP in an auditory oddball paradigm in mild AD (n=25), severe AD (n=12), age-matched normal aged controls (n=17), and young controls (n=7). The amplitude and latency of target P300 components were compared among 4 groups. The relationship between P300 measures and neuro psychological test (K-DRS) scores were evaluated by correlations. The latency of P300 was prolonged in AD and the effects were correlated with the severity of dementia. The P300 amplitude was not affected significantly in AD. Theres no difference between normal aged group and young group. These results suggest that the P300 component is specifically affected by Alzheimer type dementia.

  • Objectives : The aim of this study was to describe the clinical aspects in dementia outpatients who visited oriental neuropsychiatry clinic and to analyze the efficacy of herbal medicine. Methods: We analysed medical records of dementia outpatients who visited oriental neuropsychiatry clinic of K medical center from August. 2000 to July, 2010 and matched our criteria. Results: Ninety-two subjects were selected for analysis and consisted of 77.3% dementia of Alzheimer type. 13.0% vascular dementia. and 9.8% mixed type of dementia. Herbal medicine prescribed mainly were Jowjseungchung-tang(Tiaowejshengqing-tang). Kunneo-tang(Jjannao-tang) and Chenwangbosim-dan(Tianwangbuxin-dan) for dementia of Alzheimer type, and Sunghyangjungki-san(Xjngxjangzhengqi-san) and Upung-dan (Yufeng-dan) for vascular dementia. Scores of K-DRS were not changed for some subs cales and decreased but less than natural decline of Alzheimer disease. Score on the Memory subscale in group of Kunneo-tang(Jjannao-tang) increased significantly. Conclusions : These results suggest that the herbal medicine may be effective for dementia. More prospective studies are needed to assess the efficacy and prognosis of herbal medicine for dementia. Clinical guideline is needed for systematic data accumulation.

  • We propose a method to automatically predict Alzheimer's disease from speech data using the ChatGPT large language model. Alzheimer's disease patients often exhibit distinctive characteristics when describing images, such as difficulties in recalling words, grammar errors, repetitive language, and incoherent narratives. For prediction, we initially employ a speech recognition system to transcribe participants' speech into text. We then gather opinions by inputting the transcribed text into ChatGPT as well as a prompt designed to solicit fluency evaluations. Subsequently, we extract embeddings from the speech, text, and opinions by the pretrained models. Finally, we use a classifier consisting of transformer blocks and linear layers to identify participants with this type of dementia. Experiments are conducted using the extensively used ADReSSo dataset. The results yield a maximum accuracy of 87.3% when speech, text, and opinions are used in conjunction. This finding suggests the potential of leveraging evaluation feedback from language models to address challenges in Alzheimer's disease recognition.

  • The changes of electroencephalogram(EEG) in patients with dementia are most commonly studied by analyzing power or magnitude in certain traditionally defined frequency bands. However because of the absence of an identified metric which quantifies the complex amount of information, there are many limitations in using such a linear method. According to chaos theory, irregular signals of EEG can also result from low dimensional deterministic chaos. Chaotic nonlinear dynamics in the EEG can be studied by calculating the correlation dimension. The authors have analyzed EEG epochs from three patients with dementia of Alzheimer type and three matched control subjects. The multichannel correlation dimension is calculated from EEG epochs consisting of 15 channels with 16,384 data points per channel. The results showed that patients with dementia of Alzheimer type had significantly lower correlation dimension than non-demented controls on 12 channels. Topographic analysis showed that the correlation dimensions were significantly lower in patients with Alzheimer's disease on frontal, temporal, central, and occipital head regions. These results show that brains of patients with dementia of Alzheimer type have a decreased complexity of electrophysiological behavior. We conclude that the nonlinear analysis such as calculating correlation dimension can be a promising tool for detecting relative changes in the complexity of brain dynamics.

  • This research explored the clothing behavior of dementia inpatient according to the dementia severity, dementia type and demographic characteristics. Data were collected by surveying 149 dementia inpatients and their caregivers. The collected data were analysed through frequency analysis, $X^2$-test, one way ANOVA, Duncan's multiple range test and t-test. The results were as follows: First, the dementia severity was classified into the severe, moderate and mild dementia by K-MMSE and the dementia types were composed of Alzheimer's disease, vascular dementia and the others. The severe dementia group and Alzheimer's disease group included the more aged and more female inpatients. And the severe dementia group was lower self-support of the basic activities of daily living than the mild dementia group. Second, the change motions of the dementia inpatient's clothing differed from the clothing item and dementia severity. That is, the motions for pants were more difficult than those for upper garment. And the motions for severe dementia group were more difficult than those for the mild dementia group. Third, there were significant differences among the three groups by dementia severity and between the male and female dementia inpatient in the clothing behavior. Most of abnormal clothing behaviors were found in the severe dementia group. The positive clothing behaviors appeared in the mild dementia group. And interests of clothing and appearance appeared in the female inpatients.
