Risk factors for impulse control disorders and related behaviors in Parkinson's disease: secondary analyses of the ICARUS study.

Impulse control disorders and related behaviors (ICDs) are common in patients with Parkinson's disease (PD), yet incidence and predictive factors are not fully understood. We examined the epidemiology of ICDs in PD through secondary and analyses of data from the ICARUS (SP0990) study, which enrolled >1000 patients. Using a modified-Minnesota Impulsive Disorders Interview (mMIDI), ICD incidence was calculated for patients who were ICD-negative at baseline but ICD-positive at year 1, and year 1 and/or 2 (cumulative 2-year ICD incidence).

ICARUS study: prevalence and clinical features of impulse control disorders in Parkinson's disease.

Background: Impulse control disorders/other compulsive behaviours ('ICD behaviours') occur in Parkinson's disease (PD), but prospective studies are scarce, and prevalence and clinical characteristics of patients are insufficiently defined.

Objectives: To assess the presence of ICD behaviours over a 2-year period, and evaluate patients' clinical characteristics.

Methods: A prospective, non-interventional, multicentre study (ICARUS (Impulse Control disorders And the association of neuRopsychiatric symptoms, cognition and qUality of life in ParkinSon disease); SP0990) in treated Italian PD outpatients.

Chronic treatment with reboxetine by osmotic pumps facilitates its effect on extracellular noradrenaline and may desensitize alpha(2)-adrenoceptors in the prefrontal cortex.

1. This study investigated the effect of acute (2 days) and chronic (14 days) treatment with a selective inhibitor of noradrenaline uptake, reboxetine (10 mg kg(-1) day(-1)) by osmotic pumps, on extracellular noradrenaline and the sensitivity of alpha(2)-adrenoceptors in the prefrontal cortex of rats. 2.

Long-Term Nicergoline Treatment of Mild to Moderate Senile Dementia : Results of a Multicentre, Double-Blind, Placebo-Controlled Study.

The efficacy and tolerability of nicergoline were evaluated in a long-term, double-blind, placebo-controlled trial. 108 patients, fulfilling DSM III-R criteria for mild to moderate senile dementia of degenerative, vascular or mixed origin, were selected from a pool of outpatients attending five Italian neurological centres and randomised to receive nicergoline 30mg twice daily (54 patients) or placebo (54 patients) for 12 months. Treatment efficacy on cognitive and behavioural performances was assessed by the Sandoz Clinical Assessment Geriatric scale (SCAG) and Mini Mental State Examination (MMSE), at baseline and after 3, 6, 9 and 12 months of treatment.
