Undernutrition is a frequent problem in hospitals (at least 30% of patients, SENECA-NHANES studies). Its impact on morbidity and mortality is well known in gerontology, oncology and intensive care. There are very few neurovascular studies dealing with the consequences of undernutrition present before the stroke. Indeed, most of the medical literature concerns only undernutrition acquired after a stroke. The investigator propose to analyze medical data from a cohort of patients over 70 years of age thrombolysed and/or thrombectomized in the neurovascular department between the years 2014 and 2019.

Inclusion Criteria:

• Patients over 70 years of age with cerebral infarction, thrombolysed and/or thrombectomized between 2014 and 2019, managed in the Neurology and Neurovascular Department of the Paris Saint-Joseph Hospital
• French-speaking patient

Exclusion Criteria:

• Patients with non-thrombolyzed stroke
• Patient with a TIA (Transient Ischemic Attack)
• Patient under guardianship or curatorship
• Patient deprived of liberty
• Patient under court protection
• Patients who object to the use of their data for this research
