DYT1 primary torsion dystonia is an autosomal dominant movement disorder due to a 3-bp GAG deletion in the TOR1A gene, which becomes manifest in only 30-40% of mutation carriers. Investigating the factors regulating this reduced penetrance might add new insight into the mechanisms underlying the disease. The pathophysiology of dystonia has been related to(More)
Several lines of evidence indicate that motor cortex excitability can be modulated by manipulation of afferent inputs, like peripheral electrical stimulation. Most studies in humans mainly dealt with the effects of prolonged low-frequency peripheral nerve stimulation on motor cortical excitability, despite its being known from animal studies that(More)
Manipulation of afferent inputs may temporarily modulate dystonic spasms. Ten patients with writer's cramp were enrolled in a double-blind, randomized, crossover study in which the effects of transcutaneous electrical stimulation (TENS) and placebo treatment were compared. Patients were evaluated using four measures of dystonic impairment. The TENS group(More)
Several factors are believed to give rise to the late onset sporadic form of Alzheimer's disease (LOAD). We have studied the variation at the genes of three enzymes of the cholinergic system: acetylcholinesterase, butyrylcholinesterase, and choline acetyltransferase. The single nucleotide polymorphisms (SNPs) examined were: AChE rs2571598, BChE rs1355534,(More)
OBJECTIVE To investigate blood oxygenation level-dependent (BOLD) activation during somatosensory electrical stimulation of the median nerve in acute stroke patients and to determine its correlation with ischemic damage and clinical recovery over time. METHODS Fourteen acute stroke patients underwent functional magnetic resonance imaging (fMRI) during(More)
OBJECTIVE To determine whether pain is more frequent among people with Parkinson disease (PD) than among age-matched controls. DESIGN Case-control study. PATIENTS AND METHODS Logistic regression models taking into account type of pain, time between pain and PD onset, and possible confounders were used to compare 402 PD patients with 317 age-matched(More)
Executive functions play an important role in the maintenance of autonomy in day-to-day activities. Nevertheless, there is little research into specific cognitive training for Mild Cognitive Impairment (MCI). We present the results of a program which aims to teach specific strategies and metacognitive abilities in order for patients to be able to carry out(More)
BACKGROUND Hashimoto's encephalopathy (HE) is a condition believed to complicate Hashimoto's thyroiditis (HT). The diagnosis is suspected in the presence of high levels of serum anti-thyroid antibodies. We have recently demonstrated that in patients with HE there is an intrathecal synthesis of anti-thyroid antibodies, and concluded that the diagnosis of HE(More)
BACKGROUND AND PURPOSE Recent multiple sclerosis (MS) prevalence studies classify Italy as a high-risk area without intra-regional latitude effect. OBJECTIVES To determine MS prevalence in Verona, Italy, and frequency of myelin oligodendrocyte glycoprotein (MOG) gene G511C polymorphism and HLA-DRB1*15 locus in a sample of cases and healthy controls.

Perception of limb position and motion is abnormal in Parkinson's disease (PD). Despite the fact that the processing of proprioceptive inputs is inherently temporal, most studies have assessed spatial aspects of proprioception in PD patients. Here, we use a recently described method to test whether deficits also exist in temporal discrimination of(More)
