Recruitment & Eligibility

Status
Recruiting
Sex
Not specified
Target Recruitment
250
Inclusion Criteria

- First-ever ischemic stroke.
- MMSE score *15 (to ensure valid testing).
- Written informed consent.
- Sufficient knowledge of the Dutch language.
- Participation of informant.

Exclusion Criteria

- Recurrent stroke.
- Age younger than 40 years (to exclude atypical strokes).
- Pre-stroke dementia (assessed by a semi-structured interview with a relative, based on DSM-IV criteria of dementia).
- Psychiatric and neurological disease other than the qualifying event known to affect cognition such as schizophrenia, bipolar disorder, substance abuse, Parkinson*s disease, or epilepsy.
- Current episode of depression at admission (as evidenced by medical records and patient or informant interview). In contrast, a lifetime history of depression will not be considered as a reason for exclusion as this is considered a potential risk factor for PSD.
- Severe aphasia (as it interferes with understanding and following test instructions).

Primary Outcome Measures
NameTimeMethod
<p>The main study parameters are a) vascular cognitive impairment (this term<br /><br>includes both vascular MCI and post-stroke dementia and is therefore broadly<br /><br>defined as a score * 1.5 standard deviations below the general population mean<br /><br>(based on available norm scores); also, it must represent a significant decline<br /><br>from premorbid levels of functioning (based on informant interview and<br /><br>patient's self-report), and considered a consequence of vascular<br /><br>insufficiency/disease), b) minor or major depression as defined by a diagnostic<br /><br>interview and severity ratings, and c) apathy defined by symptoms frequency<br /><br>severity ratings.</p><br>
Secondary Outcome Measures
NameTimeMethod
<p>Secondary endpoints include a) slope analyses of neuropsychological<br /><br>trajectories in the domains of memory, executive functions, attention and<br /><br>information processing speed during the observational period, b) incident<br /><br>post-stroke dementia, c) mortality, d) recurrent stroke events, e) quality of<br /><br>life and f) level of disability.<br /><br><br /><br>Other study parameters are: comprehensive baseline assessments, which include<br /><br>history of depression, medical history, 3T structural brain MRI, blood samples<br /><br>to determine levels of inflammatory and immunological markers (acute response<br /><br>proteins, cytokines, cell adhesion molecules, antibodies), and DNA (for genetic<br /><br>testing of candidate genotypes). </p><br>
