Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to learn about epilepsy after a stroke (post-stroke epilepsy). The main questions it aims to answer are:

* What make some patients develop epilepsy after a stroke?
* Does sleep have an impact on the development of post-stroke epilepsy?

Participants will undergo:

* Electroencephalography (EEG)
* Magnetic resonance imaging (MRI)
* Polysomnography (only patients)

Blood tests will also be taken. The patient group will be compared to the healthy controls. Researchers will also look into medical records of stroke patients hospitalized at St. Olavs hospital and collect relevant information.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aims to study risk factors and clinical factors which might contribute to the development of post-stroke epilepsy. Researchers will look at the volume and size of the stroke-induced brain lesions and analyze inflammation markers. Patients and controls will undergo EEG and MRI. The correlations between sleep and epilepsy after a stroke will also be investigated through polysomnography. Relevant information about for instance age, comorbidities and NIHSS will be collected. Researchers will also collect relevant information from medical records of stroke patients hospitalized at St. Olavs hospital.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Stroke patients

Patients with first time stroke admitted to the stroke unit, St. Olavs hospital, Trondheim, Norway. The planned cohort size is 15-20 patients.

No interventions assigned to this group

Healthy controls

Age and gender matched healthy volunteers without previous stroke. The same number of healthy controls as recruited patients will be recruited through ads in the local newspaper.

No interventions assigned to this group
