Default mode network resting state activity in posterior cingulate cortex is abnormally reduced in Alzheimer disease (AD) patients. Fluctuating cognition and electroencephalogram abnormalities are established core and supportive elements respectively for the diagnosis of dementia with Lewy bodies (DLB). Our aim was to assess whether patients with DLB with(More)
Autoscopic phenomena are psychic illusory visual experiences consisting of the perception of the image of one's own body or face within space, either from an internal point of view, as in a mirror or from an external point of view. Descriptions based on phenomenological criteria distinguish six types of autoscopic experiences: autoscopic hallucination,(More)
AIMS OF THE STUDY Earlier P300 studies were conducted when the prevalence of dementia with Lewy Bodies (DLB) was unknown. Our study aims to examine whether P300 abnormalities are present in DLB and to evidence possible differences between DLB and Alzheimer's disease (AD). A second aim of this study is to look for correlations between P300 recordings and(More)
Persistent Genital Arousal Disorder (PGAD) refers to the experience of persistent sensations of genital arousal that are felt to be unprovoked, intrusive and unrelieved by one or several orgasms. It is often mistaken for hypersexuality since PGAD often results in a high frequency of sexual behaviour. At present little is known with certainty about the(More)
The study was designed to investigate the possible occurrence of “wearing-off” (WO) during dopamine agonist (DA) monotherapy. Sixty patients with “de novo” idiopathic PD were randomised into one of two DA monotherapy branches to receive oral ropinirole at 15 mg per day, or pramipexole at 2.1 mg per day. DA doses could be increased in the following two years(More)
Blink reflexes (BR) to electric stimuli of the supraorbital nerve were recorded in 26 patients with dementia with Lewy bodies (DLB), 26 patients with multiple system atrophy, 26 patients with Parkinson's disease, with or without REM sleep behaviour disorder (RBD), and in 20 patients with Alzheimer's disease and 20 with progressive supranuclear palsy without(More)
Visual Hallucinations (VH) are a common non-motor symptom of Parkinson's Disease (PD) and the Lewy body dementias (LBD) of Parkinson's disease with dementia (PDD) and Dementia with Lewy Bodies (DLB). The origin of VH in PD and LBD is debated: earlier studies considered a number of different possible mechanisms underlying VH including visual disorders, Rapid(More)
Paradoxical kinesia (PK) is the sudden resolution of a previously stabilized akinesia in an advanced idiopathic Parkinson’s disease (IPD) patient facing an immediate threat. We are reporting the effect of PK, as a consequence of a life threatening event (earthquake), in a group of 14 patients with parkinsonism and dementia in Hoehn/Yahr (H/Y) stage 3–5. All(More)
Our review summarizes the five main studies conducted to evaluate the efficacy and pharmacokinetics of ropinirole prolonged release (PR) in Parkinson's disease (PD). The PR formulation was developed with Geomatrix coating technology in order to obtain constant pharmacokinetics throughout 24 hours. The areas under the curve were not significantly different(More)
