Alpha-dihydroergocryptine in Parkinson's disease: a multicentre randomized double blind parallel group study.

Introduction: A multicentre randomized double-blind parallel group study was carried out on 68 patients suffering from idiopathic Parkinson's disease (PD) treated with L-dopa for at least 1 year with inadequate therapeutic responsiveness. The aim of the study was to compare the efficacy of alpha-dihydroergocryptine (alpha-DHEC) vs lisuride as an adjunct therapy to L-dopa on dyskinesias and clinical fluctuations (Unified Parkinson's Disease Rating Scale [UPDRS] part IV), on the symptoms pattern (Columbia University Rating Scale [CURS]), on disability (Northwestern University Disability Scale [NUDS]), and to evaluate the incidence of adverse events.

Patients And Methods: Thirty-two patients (18 males, 14 females with a mean age of 64.

Platelet glycine, glutamate and aspartate in primary headache.

Platelet levels of glutamic and aspartic acid and glycine were measured in patients with migraine with aura, migraine without aura, tension headache and cluster headache. High levels of these amino acids were found in patients with migraine with aura compared to normal subjects and other headache groups. During headache, glutamate levels further increased in migraine with aura patients.

Personality and memory in childhood migraine.

A series of neuropsychological tests were administered to a group of healthy children and another group suffering from common migraine. The tests demonstrated that children with common migraine do not have definitely abnormal personality traits even though inhibition of aggressivity and greater anxiety levels following certain environmental stimuli were seen. We also observed a decreased short- and long-term memory function in children with common migraine.
