Details

Ictus [1, 2] is a cohort of 1380 patients with Alzheimer disease followed-up in 12 European countries. These patients were included between February 2003 and July 2005 in 29 centres specialized in neurology, geriatrics, psychiatry, or psycho-geriatrics with a recognized experience in the diagnosis and management of Alzheimer disease. Most of these patients were seen during memory consultations and included consecutively. These patients were examined at six-month intervals over two years. Each examination included (though not exclusively) an Mini Mental Score (MMS) assessment.

The dataset "ictusShort" is a subset of the cohort Ictus. Since the acces to Ictus is submited to conditions, the original data have been transform before inclusion in the package, but the results of the analysis using kmlShape are the same on the real Ictus and ictusShort.
