Dance therapy improves motor and cognitive functions in patients with Parkinson's disease.

Objective: To explore the effects of Dance Therapy (DT) and Traditional Rehabilitation (TR) on both motor and cognitive domains in Parkinson's Disease patients (PD) with postural instability.

Methods: Sixteen PD patients with recent history of falls were divided in two groups (Dance Therapy, DT and Traditional Rehabilitation, TR); nine patients received 1-hour DT classes twice per week, completing 20 lessons within 10 weeks; seven patients received a similar cycle of 20 group sessions of 60 minutes TR. Motor (Berg Balance Scale - BBS, Gait Dynamic Index - GDI, Timed Up and Go Test - TUG, 4 Square-Step Test - 4SST, 6-Minute Walking Test - 6MWT) and cognitive measures (Frontal Assessment Battery - FAB, Trail Making Test A & B - TMT A&B, Stroop Test) were tested at baseline, after the treatment completion and after 8-week follow-up.

Comparison of two neural network classifiers in the differential diagnosis of essential tremor and Parkinson's disease by (123)I-FP-CIT brain SPECT.

Purpose: To contribute to the differentiation of Parkinson's disease (PD) and essential tremor (ET), we compared two different artificial neural network classifiers using (123)I-FP-CIT SPECT data, a probabilistic neural network (PNN) and a classification tree (ClT).

Methods: (123)I-FP-CIT brain SPECT with semiquantitative analysis was performed in 216 patients: 89 with ET, 64 with PD with a Hoehn and Yahr (H&Y) score of ≤2 (early PD), and 63 with PD with a H&Y score of ≥2.5 (advanced PD).

Restless legs syndrome and periodic limb movements after ischemic stroke in the right lenticulostriate region.

We report the first instance of restless legs syndrome (RLS) associated with periodic limb movements (PLM) and disruption of sleep architecture occurring in a patient following ischemic infarction in the right lenticulostriate region. Recently, a role for the basal ganglia-brainstem system in the control of motor behaviors and in the regulation of awake-sleep states has been proposed. The purported roles of these structures may be relevant in explaining the occurrence of the RLS in our patient.

Neuropsychophysiological findings in a case of long-standing overt ventriculomegaly (LOVA).

Long-standing overt ventriculomegaly in adults (LOVA) is a clinical entity characterized by chronic hydrocephalus with infant onset, slow evolution and clinical disturbances during adulthood. Few cases are reported in literature describing the evident contrast between the severity of hydrocephalus and the relatively spared neurological functioning and cognitive aspects. The authors describe a 59-year-old man with congenital hydrocephalus complaining of persistent gait impairment.
