Introduction: Obstructive sleep apneas are a frequent clinical condition in which there are momentary interruptions or reductions in breathing activity. To date, the gold standard therapy is the use of Continous Positive Airway Pressure (CPAP). But, due to the relatevely high frequency of poor compliant patients, there is the need to research...

Sleep represents an active phenomenon regulated by a highly integrated network of cortical and subcortical structures. This complex model results in disruptions at various levels during physiological aging and more deeply during neurodegenerative disorders, thus leading to different sleep alterations. In Alzheimer's disease (AD), sleep-wake...

The presence of polysomnography-confirmed REM sleep behavior disorder (RBD) is the stronger risk factor for having prodromal Parkinson disease (PD), followed by abnormal presynaptic dopaminergic radionuclide neuroimaging. Aim of the review is to conduct a meta-analysis of literature data regarding presynaptic dopaminergic neuroimaging in RBD. A...

The objective of this study was to assess the role of cognitive evaluation in the prediction of phenoconversion in polysomnography-confirmed idiopathic or isolated rapid eye movement sleep behaviour disorder, through a scoping review focussing on a longitudinal comprehensive neuropsychological assessment of patients with idiopathic REM sleep...

To search for a specific neuropsychological profile in idiopathic REM sleep Behavior Disorder (iRBD), able to predict the onset of neurodegenerative disorders.

Graph theory analysis on resting state electroencephalographic rhythms disclosed topological properties of cerebral network. In Alzheimer's disease (AD) patients, this approach showed mixed results. Granger causality matrices were used as input to the graph theory allowing to estimate the strength and the direction of information transfer...

The study of dementia and epilepsy may provide particular insight into behavioural alterations. We describe a rare case of ictal aggressive behaviour in a patient with focal epilepsy associated with a non-dominant dorso-lateral prefrontal lesion. During focal seizures, our patient showed intense agitation and anger, for a long time...

Idiopathic rapid eye movement sleep behavior disorder (iRBD) is considered to be a prodromal stage of Parkinson's disease (PD). At PD onset, 40 to 70% of the dopaminergic neurons in the substantia nigra (SN) are already lost. Thus, milder SN damage is expected in participants with iRBD. We aimed to quantify SN damage in participants with iRBD...
