OBJECTIVETo study the effects of acupuncture on Chinese medicine syndromes of vascular dementia (VaD).

METHODSSixty-three VaD patients were divided into three groups. Those willing to be randomized were randomly assigned to receive either acupuncture (random acupuncture group, 24 cases) or rehabilitation training (guided rehabilitation group, 24 cases) for 6 weeks. Those unwilling to be randomized also received acupuncture for 6 weeks (non-random acupuncture group, 19 cases). Patient syndromes and their severity were evaluated before treatment (baseline), at the end of treatment, and at 4-week follow-up after the completion of treatment using a CM scoring system (scale of differentiation of syndromes of vascular dementia, SDSVD). The SDSVD scores of the random and non-random acupuncture groups, and of all patients who received acupuncture (combined acupuncture group, 43 cases), were compared with those in the guided rehabilitation group.

RESULTSIn the random, non-random, and combined acupuncture groups, SDSVD scores were significantly reduced at the end of treatment and at follow-up than at baseline. In the guided rehabilitation group, SDSVD scores were similar to baseline scores at the end of treatment and at follow-up. However, there were no significant differences in SDSVD scores among the three groups or between the combined acupuncture group and the guided rehabilitation group at any time points. In the non-random and combined acupuncture groups, SDSVD scores were significantly reduced at the end of treatment than at baseline in patients with hyperactivity of Liver (Gan)-yang or phlegm obstruction of the orifices.

CONCLUSIONSAcupuncture reduced the severity of VaD. The improvement was the greatest in patients undergoing their treatment of choice. Treatments in this study were more effective for excess syndromes, such as Liver-yang hyperactivity or phlegm obstruction of the orifices than deficiency syndromes, such as Kidney (Shen)-essence deficiency.

Alzheimer's disease (AD) is characterized by decreased neuronal activity and atrophy, while hyperactivity of neurons seems to make them resistant to aging and neurodegeneration, a phenomenon which we have paraphrased as 'use it or lose it'. Our hypothesis proposes that (1) during their functioning, neurons are damaged; (2) accumulation of damage that is not repaired is the basis of aging; (3) the vulnerability to AD is determined by the genetic background and the balance between the amount of damage and the efficiency of repair, and (4) by stimulating the brain, repair mechanisms are stimulated and cognitive reserve is increased, resulting in a decreased rate of aging and risk for AD. Environmental stimulating factors such as bilingualism/multilingualism, education, occupation, musical experience, physical exercise, and leisure activities have been reported to reduce the risk of dementia and decrease the rate of cognitive decline, although methodological problems are present.

INTRODUCTIONHyperfamiliarity, a phenomenon in which feelings of familiarity are evoked by novel stimuli, is well described in epilepsy and the lesioned brain. Abnormality of familiarity in Alzheimer's disease (AD) and mild cognitive impairment (MCI) have also been described in the literature, but more from a neuropsychological approach perspective. Currently, there is a lack of study on the real-life experience of familiarity abnormality in dementia and MCI. Our aim was to compare the occurrence of hyperfamiliarity among dementia and MCI.

MATERIALS AND METHODSWe recruited 73 participants, 29 with AD, 10 with vascular dementia, 7 with MCI and 27 healthy controls, and administered a questionnaire to assess hyperfamiliarity frequency.

RESULTSHyperfamiliarity was observed in real-life in cognitive impairment, but was unrelated to its severity or underlying aetiology.

CONCLUSIONThis study highlights the similar rate of occurrence of hyperfamiliarity in the daily life of individuals with cognitive impairment. Future research should examine neuropsychological correlations and mechanisms that contribute to such observations.

OBJECTIVETo verify the therapeutic effect of vascular dementia treated with three-line puncture on the Governor Vessel and Bladder Meridian on head.

METHODSSixty cases were randomly divided into a head-line puncture group and a routine acupuncture group, 30 cases in each group. In head-line puncture group, line puncture was applied on three lines of the Governor Vessel and Bladder Meridian from anterior hairline to occipital tuberosity. In routine acupuncture group, Yintang (GV 29), Fengchi (GB 20), Sishencong (EX-HN 1) penetrating to Baihui (GV 20) and Shenting (GV 24) penetrating to Shangxing (GV 23) were selected. Once a day, 5 times in a week and 8 weeks totally. Score was evaluated with Mini-Mental State Examination scale (MMSE) before and after treatment, and the therapeutic effects in both groups were compared.

RESULTSThe total effective rate of cognitive function was 76. 7% (23/30) in head-line puncture group, superior to that of 43.3% (13/30, P < 0.05) in routine acupuncture group. The MMSE scores in both groups were improved after treatment (both P < 0.01), and it in head-line puncture group was superior to that in routine acupuncture group (P < 0.01).

CONCLUSIONThree-line acupuncture on the Governor Vessel and Bladder Meridian on head can remarkably improve the cognitive function of vascular dementia, and the therapeutic effect is superior to that of routine acupuncture.

OBJECTIVETo study the effects of electro-acupuncture (EA) on electroencephalography (EEG) in vascular dementia (VD) patients.

METHODSAccording to the Hasegawa dementia scale (HDS), the severity of 46 VD patients were classified into three grades as gentle, medium and severe, in the same time, they were divided into the EA group (n = 23) and the nimotop group (n = 23) randomly. Changes of EEG in the patients were observed before and after treatment.

RESULTSThe degree of normality of EEG in VD patients were positively correlated with the severity of their illness, i. e. the severer VD, the more obvious the abnormal EEG changes.

CONCLUSIONEEG can be accessible for evaluating the severity of VD, and the electrical activity of brain in VD patients could be improved by EA therapy.

The Seoul Neuropsychological Screening Battery (SNSB) is one of the standardized neuropsychological test batteries widely used in Korea. However, it may be a bit too lengthy for patients with decreased attention span; and it does not provide the score of global cognitive function (GCF), which is useful for monitoring patients longitudinally. We sought to validate a dementia version of SNSB (SNSB-D) that was shorter than the original SNSB and contained only scorable tests with a GCF score of 300. We administered SNSB-D to patients with mild cognitive impairment (MCI) (n=43) and Alzheimer's disease (AD) (n=93), and normal controls (NC) (n=77). MCI and AD groups had GCF scores significantly different from NC group, and GCF scores were able to distinguish patients with Clinical Dementia Rating of 0.5 and 1. Test-retest reliability was high, with a correlation coefficient of 0.918 for AD, 0.999 for MCI, and 0.960 for NC. The GCF score significantly correlated with the Mini-Mental State Examination (MMSE). Through ROC-curve analysis, GCF scores were found to yield more accurate diagnoses than the MMSE. The SNSB-D is a valid, reliable tool for assessing the overall cognitive function, and can be used to monitor cognitive changes in patients with dementia.
