Unawareness of deficits is a symptom of Alzheimer's disease that can be observed even in the early stages of the disease. The frontal hypoperfusion associated with reduced awareness of deficits has led to suggestions of the existence of a hypofunctioning prefrontal pathway involving the right dorsolateral prefrontal cortex, inferior parietal lobe, anterior(More)
The comprehension of non-literal language was investigated in 20 probable Alzheimer's disease (pAD) patients by comparing their performance to that of 20 matched control subjects. pAD patients were unimpaired in the comprehension of conventional metaphors and idioms. However, their performance was significantly lower in the case of non-conventional (novel)(More)
20 depressed and 20 non depressed patients with Parkinson disease were rated for disability on the Northwestern University Disability Scale and for severity of the "typical" motor symptoms on the Columbia University Rating Scale and were assessed for mental deterioration. The severity of the "typical" symptoms was practically equivalent in the two groups(More)
The present study analyzed the awareness of deficits in 117 mild Alzheimer's disease participants. Since few studies have examined the cognitive and behavioral domains of reduced awareness in detail, we performed a domain-specific assessment using the Awareness of deficit Questionnaire - Dementia scale with the novel aim of describing the relationship with(More)
BACKGROUND Although dyskinesias-reduced-self-awareness (DRSA) in Parkinson's disease (PD) is related to deficit in metacognition, other factors, such as "Theory of Mind" (ToM), could operate. METHODS Forty-one PD patients were assessed using the Global Awareness of Movement Disorders (GAM) and the Dyskinesias Subtracted-Index (DS-I). To study whether GAM(More)
Chronic inflammation significantly contributes to the pathogenesis of several neurodegenerative disorders. In physiological conditions, a chronic inflammatory state is prevented through the termination of the acute inflammatory response once the triggering insult is eliminated. Several mechanisms regulate the resolution of inflammation. Among these, a(More)
Parkinson’s disease (PD) is a neurodegenerative pathology characterized by the degeneration of midbrain dopamine neurons, whose development and maintenance in brain is related to the transcription factor NR4A2 (also called Nurr1). Notably, NR4A2 is a neuroprotective agent with anti-inflammatory role in microglia and astrocytes. Furthermore, mutations in(More)
Reduced awareness of illness is a well-known phenomenon that has been studied in patients with vascular disease, but the precise nature of their executive dysfunction is an intriguing question that still has to be resolved. It would be particularly interesting to study patients with reduced awareness of disease possibly related to vascular lesions of the(More)
The study analyzes the presence of dyskinesias-reduced-self-awareness in forty-eight patients suffering from Parkinson's disease (PD). As the association with executive dysfunction is a matter of debate and we hypothesize it plays an important role in dyskinesias self-unawareness, we analyzed the role of dopaminergic treatment on the(More)
