Evolution of migraine after a 10-year follow-up.

Objective: To assess the evolution of headaches in a workplace cohort over a 10-year period.

Background: Migraine headaches are associated with significant handicap in everyday activities and poor quality of life. The prevalence of migraine shows a bell-shaped age distribution with a peak during the third and fourth decades.

Association between Parkinson's disease and exposure to pesticides in southwestern France.

A case-control study was performed in southwestern France in order to assess the relationship between pesticide exposure and Parkinson's disease (PD) in the elderly. During the period from 1997 to 1999, 84 cases were recruited together with 252 population-based controls. Experts in occupational health reviewed job codes and provided pesticide exposure levels, making it possible to calculate cumulated exposure lifelong for individuals.

Application of the International Cooperative Ataxia Scale rating in multiple system atrophy.

We assessed the International Cooperative Ataxia Scale (ICARS) as a means of extracting and rating cerebellar signs in multiple system atrophy (MSA). Cross-sectional analysis of internal consistency, factor structure, and correlation with parkinsonism severity (Unified Parkinson's Disease Rating Scale [UPDRS] III) of the ICARS, in 50 unselected MSA patients (mean age, 67.6 years; mean disease duration, 5.

Parkinsonism in multiple system atrophy: natural history, severity (UPDRS-III), and disability assessment compared with Parkinson's disease.

We analyzed parkinsonian features in multiple system atrophy (MSA) compared with age- and disease duration-matched Parkinson's disease (PD) patients, and assessed the applicability of the Unified Parkinson's Disease Rating Scale (UPDRS) -III motor scale as a means of rating their severity. Cross-sectional analysis of parkinsonism was done using UPDRS-III, International Cerebellar Atatia Rating Scale, and disability scales (Hoehn and Yahr [H&A], Schwab and England, Katz and Lawton) in 50 unselected MSA patients and in 50 matched PD patients. At symptom onset, falls occurred 10 times more frequently in MSA, whereas limb tremor was 10 times more common in PD.
