The efficacy of a centrally active cholinesterase inhibitor, rivastigmine tartrate (ENA 713), in patients with advanced moderate Alzheimer's disease (AD) was evaluated in a 12-month placebo-controlled study. We aimed to investigate whether there was any evidence for the benefits of rivastigmine in patients with severe disease. These patients were compared(More)
OBJECTIVES The aim of this study was to evaluate the relationship between homocysteine (Hcy), folate and vitamin B12 levels in vascular dementia (VaD) and Alzheimer Disease (AD) to elucidate if they had similar pathogenesis due to cerebrovascular injury. DESIGN AND METHODS Plasma Hcy and serum folate, vitamin B12 levels were studied 67 VaD, 51 AD and 40(More)
BACKGROUND Alzheimer's disease (AD) is a neurodegenerative disorder in middle and late age. Ribosomal RNA (rRNA) genes are located in the nucleolus (nucleolar organizer regions = NORs). There are increased deposits of beta-amyloid protein in the brains of the patients with AD and aged individuals with Down's syndrome (DS). The beta-amyloid gene is located(More)
Sarcoidosis is a multisystemic disease characterized by granulomatous inflammation. Lung or lymph node involvement is common. We present a rare case of sarcoidosis that began with orbital involvement, and a month later, due to insufficient treatment, it involved the central nervous system. A 49-year-old female patient began suffering from swelling in her(More)
Alzheimer's Disease is the leading neurodegenerative cause of dementia. The pathogenesis is not clearly understood yet, is believed to be the complex interaction between genetic and environmental factors. Consequently vascular risk factors and Apolipoprotein E genotyping are increasingly gaining importance. This study aimed at assessing the relationships(More)
Status epilepticus (SE) can be harmful to the developing brain. Our knowledge of the emotional and behavioral consequences of generalized SE in developing animals remains limited. Therefore, we investigated the short- and long-term effects of pentylenetetrazole (PTZ)-induced SE on emotional memory and learning and behavioral parameters in immature rats. SE(More)
