| Abstract:: |
| bjective To evaluate the effects of long-term low dose and low dose-rate ionizing radiation exposure on the prevalence rate of senile dementia,further assess the effects of low dose radiation exposure on central nervous system and study the pathogen of senile dementia,and provide direct observational data of human beings. Methods A cross-sectional study of the prevalence of senile dementia was carried out in high background radiation areas in Yangjiang,Guangdong Province,China.The survey was conducted in two stages.For the initial screening,Hasegawa Dementia Scale (HDS) was used for all subjects.In the second stage, the stage of diagnosis,special questionnaires of healthy state of old people were used. The final diagnoses were made according to the third revised edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM Ⅲ-R) of American Psychiatric Association. Results 1018 inhabitants aged 65 years and over,including 513 persons in HBRA and 505 in CA were oberved.According to DSMⅢ-R,61 cases (31 cases in HBRA and 30 cases in CA)of senile dementia were diagnosed.The prevalence rates of senile dementia are 6.04% in HBRA and 5.94% in CA,the total prevalence rate being 5.99%. Conclusion No significant statistical difference in the prevalence rate of senile dementia between the two areas was found,suggesting that the prevalence rate of senile dementia in these areas is not associated with the high background radiation exposure. |
