Brief Summary
Cognitive impairments such as memory impairments, word-finding difficulties, compromised orientation and perception are often observed in stroke patients. Low serum-mg-concentrations are associated with cognitive impairments in ischemic stroke patients one month after stroke onset. It is not clear, if cognitive impairments after stroke is caused by the mg-deficiency or by the stroke itself. Until now, no studies investigating the relationship between mg-concentration, stroke severity and cognition during treatment course are available. Thus, this study aimed to investigate the relationship between mg-concentration and cognition of stroke patients.

Stroke Patients
Ischemic-/hemorragic stroke patients, who admitted on the stroke unit.
Interventions
The cognitive state of the patient is measure by the Kölner Neuropsychologische Screening (KöpSS) and by the Mini Mental Status Test (MMST). The MMST is a popular often used test, which makes comparisons to other international studies possible. However, even though this test was specifically designed for stroke patients, it has a limited sensibility. Thus the KöpSS is being used as an additional test demonstrating satisfactory sensibility and specificity. It is suitable for acute and subacute strokes and covers all stroke relevant domains.
Eligibility Criteria
The sample is comprised of 80 stroke patients (ischemic/hemmorgic) of both genders and age ≥ 18 years. A written consent form is signed before inclusion.
You may qualify if:
- ischemic/hemmorhagic stroke
- written consent form
You may not qualify if:
- pre-existing dementia or cognitive impairment before stroke onset
- pre-existing mental disorder (depression) or present/prior long-term treatment (\> 6 months) with psychotropic drugs
- pre-existing malign tumor disease
- participation in another clinical trial within the past 30 days
- pregnancy or breastfeeding
