Eligibility
Inclusion criteria
Inclusion criteria: Patients with lacunar stroke, patients with mild vascular cognitive impairment (VCI), and healthy subjects will be included. Criteria for all subjects: 1. Age >18 year. Criteria specifically for lacunar stroke patients: 1. A first-ever acute lacunar stroke. Criteria specificaly for mild VCI due to cerebral small vessel disease (cSVD): 1. Subjective complaints of cognitive functioning and objective cognitive impairment in at least 1 cognitive domain on cognitive testing, and; 2. A Clinical Dementia Rating ≤1 and a MMSE ≥20 (i.e. no dementia), and; 3. Vascular lesions on brain MRI (lacunar infarts, white matter lesions, deep microbleeds) that suggest a link between the cognitive deficit and cSVD. Healthy control subjects: 1. Healthy control subjects included from the general and matched to the LACI and mild VCI patients according to gender and age.
Exclusion criteria
Exclusion criteria: Exclusion criteria for all subjects: 1. Age <18 year; 2. Cerebrovascular abnormalities in history: A. Ischemic stroke; B. Haemorrhagic stroke (subarachnoid or intracerebral). 3. Contra indications for MRI/DCE-MRI: A. Heart valve prosthesis; B. Pacemaker; C. Intracerebral clips (aneurysm); D. Intra-ocular metal pieces; E. Cochlear implant; F. Claustrophobia; G. Poor kidney function (GFR<30ml/min); H. Previous allergic reaction to contrast agent (gadobutrol). 4. Psychiatric disorders associated with (temporarily) cognitive decline (e.g. depression, psychosis). Group specific exclusion criteria: Lacunar stroke: 1. Potential cardiac embolic source (e.g. atrial fibrillation); 2. Stenosis of ≥50% of one or both internal carotid arteries. Mild VCI due to cSVD: 1. Clinical and/or subclinical cortical events; 2. Other causes for cognitive impairment (e.g. Alzheimers Disease). Healthy subjects: 1. Clinically overt cardiovascular diseases; 2. Clinically overt cerebrovascular diseases; 3. Disease of the central nervous system (e.g. Multiple Sclerosis, brain tumor/metastasis); 4. Extensive structural lesions on MRI associated with cSVD; 5. Cognitive impairment (i.e. objective and/or subjective cognitive deficits).
