The aim of this study was to determine whether pattern-reversal Visual Evoked Potential (PRVEP) is affected in mild cognitive impairment (MCI). Participants aged ≥ 60 years diagnosed as MCI were invited to participate in a study together with a group of controls. PRVEP was measured using A RETI-port/Scan 21 and stimuli of large and small checks sizes, 1° (60 min of arc) and 0.25° (15 min) respectively were used to obtain responses. The amplitude and implicit times of the MCI and control groups were then compared. A total of 18 MCI participants (age 65.7 ± 3.1 years) and 18 controls (65.1 ± 3.8 years) consented to participate in the study. The amplitude and implicit times for the MCI group using the target sizes of 60 min of arc were 9.80 ± 4.06 μV and 108.83 ± 7.63 ms and for 30 min of arc were 11.00 ± 7.44 μV and 123.96 ± 6.18 ms respectively. Consecutively for the control groups the amplitudes and implicit times were 8.96 ± 3.52μV, 105.85 ± 3.60 ms and 11.97± 6.11 μV, 122.57 ± 8.28 ms. PRVEP results did not reveal significant differences in P100-wave amplitude nor implicit time between the two groups under investigation. This study concluded that the visual pathway of MCI participants may be unaffected in the early part of the disease process.

From this study, the authors have concluded: - The elderly Mong have high longevity and better health in comparison with the elderly San Diu. - The conditions of laubour, the vital enviroment and the socio- familial medium have great significant on health and sensible influence on longevity.

This study included 448 patients older than 60 years during 1992 with the following characteristics: sex: 55.58% male; 44.42% female. Geographic repartition: 57.14% from country side: 42.86% from town. Ethnic repatition: 94.64% Kinh; 3.35% Tay; 1.12% Nung and 0.89% (3 other ethnic minorities). Diseases of: gastro- intestinal tract: 27.23%. Respiratory tract: 26.56%. Cardiovascular system: 21.65%. Nervous system: 10.26%. Urinary- genital tract: 6.47%. Blood system: 2.9%. Others: 3.34%.

Subject: 1994 senior persons who were working as chiefs and managers of the Ministry of Health. Method: survey. Data was analysed by statistic method. Results: average age of senior persons is relative high. Most of them are 50-60 years old. Rate of university and upper university graduates is high. But some of them are limited in foreign language and informatics.

Changes of cardiac structure and action in elderly led to the arrhythmia such as extrasystole (symptoms, treatment and prognosis), arterial fibrillation (anticoagulation for reduction of the risk of cardiovascular accidents, reduction of ventricular rhythm, normalization of sinal rhythm), sick sinal syndrome and transmission disorders were studied.

The study was carried on 3 communes of Giao Thuy district, 2 communes of Xuan Truong district, Nam Dinh province and 3 communes of Dong Hung district, Thai Binh province. The results showed that hemoglobin levels are similar between two genders, reduce gradually consistent with age and are lowest in interior field residents. Total cholesterol level at more than 5.2mmol/l accounts for average of 12.4%; triglycerid level at more than 2.3mmol/l accounts for average of 19.9% and HDL cholesterol at less than 0.9mmol/l makes 26.4%. The rates are highest in older population. These indices have high rate in town areas, followed by coastal areas and lowest in interior field areas. The mean rate of older people who have dyslipidemia is 5.1%.

The tear production of 192 eyes was evaluated by shirmer I and 171 eyes were evaluated by shirmer II among 106 patients (male: 30). The results showed that the average value of total tear production in elderly was 8.7±6.6mm and average value of basic tear production was 6.1±4.3 mm. There was no difference of tear production was reduced with increased ages
