Study of Factors Influencing Post-stroke Dementia (strokdem)

March 25, 2021 updated by: University Hospital, Lille

Characterization of Clinical, Biological, Morphological and Pharmacological Factors Influencing Occurrence of Dementia or Cognitive Disorders After Stroke

If the risk of dementia occurrence after stroke is well known, few data exist about the factors influencing positively or negatively the developement of cognitive disorders or dementia. The aim of the study is so to determine prospectively the clinical, biological, lesional and pharmacological factors associated with post-stroke dementia by the long-term follow-up of a stroke patient cohort.

Detailed Description

The STROKDEM study is based on the 5-year prospective follow-up of a population of 1100 stroke patients without dementia. At inclusion in the cohort, main antecedents and risk factors, previous treatment and lifestyle, initial severity and etiology are recorded. Biological samples (for standard ans specialized analyses) and MRI are performed at 72h after stroke occurrence. Thereafter, patients are regularly (6 months, 12 months, 36 months, 60 months) examined for clinical and cognitive assessment with biological samples and Magnetic Resonance Imaging. Patients with dementia will be compared to patients without stroke to identify, by logistic regression analysis and Cox model, the factors associated with dementia occurrence.
