Domperidone is effective in the prevention of rivastigmine-related gastrointestinal disturbances.

Nausea and/or vomiting are frequent dose-limiting class effects of cholinesterase inhibitors, occurring mostly during the dose-escalation phase. These untoward effects make it difficult to increase rivastigmine dosage above 6 mg daily in most patients. The antiemetic domperidone was given to 22 patients with Alzheimer's disease (9 men, 13 women; mean age 74.

Pramipexole versus sertraline in the treatment of depression in Parkinson's disease: a national multicenter parallel-group randomized study.

In addition to treating the motor symptoms of Parkinson's disease, the dopamine agonist pramipexole has shown an antidepressant effect. The trials, however, included patients with motor complications, raising the question of whether the antidepressant benefit represented only a treatment-related motor improvement. To address this issue, we have conducted a 14-week randomized trial comparing pramipexole with an established antidepressant in patients without motor complications.

Autonomic nervous function in de novo parkinsonian patients in basal condition and after acute levodopa administration.

The aims of this study were to assess autonomic nervous function in subjects with recently diagnosed Parkinson's disease (de novo patients) and to evaluate its changes following acute levodopa administration. In 13 patients (8 males, 5 females) and 13 age-matched control subjects, three cardiovascular autonomic function tests (Deep Breathing, Valsalva, Lying to Standing) were performed, the QT interval was calculated on a 12-lead electrocardiogram, and the response of plasma norepinephrine to standing was assessed in basal conditions. The cardiovascular tests and the measurement of the QT interval were repeated in de novo Parkinsonian patients 90 minutes after the administration of levodopa 200 mg per os.

Apomorphine SC treatment in parkinsonian patients with long-term L-dopa syndrome during L-dopa drug holiday.

The Long-Term Dopa Syndrome (LTDS) is one of the main problems in the management of advanced parkinsonian patients. A transient L-Dopa withdrawal (Drug Holiday, DH) can be useful to improve the drug response after DH, even if this approach presents risks due to patient akinesia. We tried to verify if Apomorphine sc administration during DH (DH with Apomorphine, DHA) can: a) reduce the risks connected with DH: b) maintain the benefits of DH: c) standardize the duration of DH.

Idebenone, a new drug in the treatment of cognitive impairment in patients with dementia of the Alzheimer type.

Alzheimer's disease (AD) is a central nervous system disorder characterized by the presence of neurofibrillary tangles, neuritic plaques and dystrophic neurones in susceptible areas of the brain. Few options for treatment of AD symptomatology are available. We conducted a multicenter, randomized, double-blind, placebo-controlled, parallel trial consisting of a 90 day treatment period followed by a 30 day single blind placebo administration and by an optional long term period of treatment up to a year with idebenone in open fashion.
