The objective of this study was to evaluate the relationship between REM sleep behavior disorder (RBD), hallucinations, and cognitive impairment in Parkinson's disease (PD). One hundred and ten PD patients, divided into three groups (without RBD or hallucinations; with RBD but no hallucinations; with RBD and hallucinations), were submitted to(More)
Estrogens are known to act selectively on some components of memory, exerting beneficial effects on cognitive performances. However, there are few data on the long-term effect of the lack of estrogen in postmenopausal women. Therefore, we investigated attentive and verbal memory performances in physiological and surgical menopause, drawing attention to the(More)
There is debate over the cognitive and behavioral effects of deep brain stimulation (DBS) of the subthalamic nucleus (STN) in advanced Parkinson's disease (PD). To evaluate these effects, we performed a prospective, naturalistic controlled, 3-year follow-up study. A total of 65 PD patients were enrolled, of whom 32 underwent STN-DBS (PD-DBS) and 33, even(More)
It is well established that a reciprocal control exists between the brain and glucocorticoid hormones. The brain regulates adrenocortical function via hypothalamic corticotrophin releasing hormone-41 (CRH-41), glucocorticoids act at specific receptors in the hippocampus, thus promoting negative feedback mechanisms. Because the hippocampus is a major site(More)
A rehabilitation program of 6 weeks, including both motor and cognitive training, was applied to 20 patients affected by Parkinson's disease (PD) in the early stages, presenting with mild cognitive deficits, but no dementia. Cognitive rehabilitation has been performed by utilizing a software elaborated for neuropsychological training (TNP). At the end of(More)
In Parkinson's disease (PD) the presence of REM parasonnias as REM Behaviour Disorder (RBD) or vivid dreams/nightmares, is recognized as largely associated with hallucinations, even if the risk of the development of hallucinations seem not to depend on how long the REM parasomnias had been occurring. The aim of this study was to establish if RBDs occurring(More)
In 31 patients with probable Alzheimer’s disease (AD), 19 with probable vascular dementia (VaD) and 20 with Possible AD and Possible VaD, cerebrospinal fluid (CSF) tau levels hyperphosphorylated at threonine 181 (Ptau) were measured by ELISA. Thirty-six age-matched subjects were used as controls. The severity of the cognitive decline was assessed at the(More)
Hippocampal damage, by DTI or MR volumetry, and PET hypoperfusion of precuneus/posterior cingulate cortex (PC/PCC) were proposed as biomarkers of conversion from preclinical (MCI) to clinical stage of Alzheimer's disease (AD). This study evaluated structural damage, by DTI and MR volumetry, of hippocampi and tracts connecting hippocampus to PC/PCC(More)
Brain-derived neurotrophic factor (BDNF) promotes neuronal survival during development and protects neurons from insults of various kinds. Changes in production of BDNF have been reported in differing neurodegenerative pathologies and, in particular, in Alzheimer disease (AD). We studied 200 AD patients and 408 healthy controls for BDNF Val66Met(G196A)(More)
BACKGROUND Defects of the ubiquitin-proteasome (UP) system, a multicatalytic complex degrading polyubiquitinated proteins, may intervene in the pathogenesis of neurodegenerative disorders characterized by intracellular formation of protein aggregates such as Parkinson disease (PD) and Alzheimer disease (AD) by inducing proapoptotic conditions. METHODS The(More)
