OBJECTIVE To determine the long-term prognosis of neurologic involvement in Behçet syndrome. DESIGN Forty-six patients with Behçet syndrome, who had been the subjects of a previous report with short-term follow-up, were reexamined 7 years later; 42 of them could be reexamined neurologically. Neuropsychological testing, magnetic resonance imaging,(More)
Obsessive-compulsive disorder (OCD) is a chronic disease characterized by repetitive, unwanted intrusive thoughts and ritualistic behaviors. Studies of neuropsychological functions in OCD have documented deficits in several cognitive domains, particularly with regard to visuospatial abilities, executive functioning, and motor speed. The objective of the(More)
Alzheimer's disease (AD) is a progressive neurodegenerative disorder with a poorly understood etiology. There is considerable evidence that oxidative stress occurs in AD and increased DNA damage has been found in brain tissues and leukocytes of AD patients. Base excision repair (BER) is the major pathway responsible for removing oxidative DNA damage.(More)
Identifying early-detection biomarkers have become an increasingly important approach in the treatment and prevention of Alzheimer's disease (AD). In this study, we investigated the potential of brain-derived neurotrophic factor (BDNF), complement factor H (CFH), tumor necrosis factor-α (TNFα), interleukin 10 (IL-10), and heat shock protein 90 (Hsp90) as(More)
BACKGROUND/AIMS The polymorphism (rs1800587) in the 5'-flanking regulatory region at -889 of the interleukin-1alpha gene has been shown to be associated with inflammatory diseases and Alzheimer's disease (AD). The aim of the current study is to determine whether there is an association between the promoter region polymorphism of the interleukin-1alpha gene(More)
Vitamin D(3) is known to be involved in neuroprotection and exert its neuroprotective effects by modulating neuronal calcium homeostasis and production of neurotrophins. The single nucleotide polymorphisms (SNP) in vitamin D receptor (VDR) gene which can influence the affinity of vitamin D(3) to its receptor may be related to neurodegenerative diseases and(More)
Sleep disturbances including excessive daytime sleepiness (EDS) are encountered in frontotemporal dementia (FTD). To investigate the relationship between the plasma orexin-A levels and sleep disturbance patterns, we measured the plasma orexin-A levels and performed sleep studies in patients with FTD. The orexin-A levels were measured in 10 consecutive(More)
Alzheimer's disease (AD) is defined pathologically by the presence of β-amyloid plaques, neurofibrillary tangles and extensive neuronal loss. Evidence indicates that increased DNA damage may contribute to neuronal loss in AD. Recently, it has been shown that in AD neurons have a reduced capacity for some types of DNA repair. Polymorphisms in DNA repair(More)
OBJECTIVE Deficient executive functioning (EF) has been reported in several neurodevelopmental disorders, including autistic spectrum disorders; however, many studies included heterogeneous groups and few have focused on EF in individuals with Asperger's disorder (AD) in relation to attentional performance. The aim of the present study was to compare(More)
There have been no serial studies about neuroradiological findings of neurosyphilis in the literature. There have been only case reports concerning HIV negative patients with neurosyphilis. We present 8 HIV negative neurosyphilis patients two of whom are women. The mean age of the patients was 48 years±12.37. Five of the 8 patients had general paresis, two(More)
