Clinical studies in the past have shown that the pathology of Alzheimer’s disease (AD) initiates, 10 to 15 years before the visible clinical symptoms of cognitive impairment starts to appear in AD diagnosed patients. Therefore, early diagnosis of the AD using potential early stage cerebrospinal fluid (CSF) biomarkers will be valuable in designing a clinical trial and proper care of AD patients....

Parkinson`s disease (PD) is the second most common neurodegenerative disorder after Alzheimer`s disease. It is a chronic and progressive disease, and mostly afflicts elderlies. PD starts with sudden onsets and the exact cause of the disease is still unknown, however there are some early symptoms that can help us to diagnose the disease and ameliorate its effects. PD is a multi-factorial disease...

Down syndrome, trisomy of chromosome 21, is well investigated because it is a genetic disease with characteristic mental retardation and precocious dementia of Alzheimer type. Maternal serum markers of human chorionic gonadotrophin unconjugated estriol and amyloid precursor protein, nuchal skinfold on ultrasound and new genetic probes are developed to allow better detection of Down syndrome. Th...

The science of medical genetics is progressing rapidly. The practical importance of this pro­gress should be considered by medical doctors. Both genetic and environmental factors are involved in the abnormail phenotypes considered diseases. The relative significance of the two factors varies from disease to disease. All di­seases can be viewed as falling on a spectrum in this regard. Hereditary...

Alzheimer's disease is considered the most common cause of dementia. At present, no definite cure is available for healing the disorders and stopping the disease progress. The aim of this study is to study the effects of piracetam, rivastigmine and their joint consumption on MMSE score status in patients with Alzheimer disease. This interventional study was carried out on 64 patients with ...

Nowadays, air pollution is one of the major problems in developed and developing countries. In recent years, effects of air pollution on neuroinflammatory diseases such as Alzheimer disease and Parkinson disease have been studied. Researches on polluted cities citizens indicate increasing in central nervous system (CNS) inflammatory factors in comparison with clean cities; also air pollution ex...

BACKGROUND Pathogenic mutations in the presenilin 1 (PS1) gene leading to early-onset Alzheimer disease have been described in various populations. The different mutations are not distributed randomly in the PS1 protein but are clustered in some PS1 exons. OBJECTIVE To screen the PS1 gene in search of a potential mutation in a Spanish family with early-onset Alzheimer disease. METHODS Singl...
