Objectives

Narrative objectives1

Elucidation of causative genes, disease susceptibility genes, and modifier genes in neurosurgical diseases (cerebrovascular disorders, epilepsy)

Basic objectives2

Others

Basic objectives -Others

Neurosurgical procedures allow to obtain tissue samples from pathological brain and vascular structures and be submitted to genetic analysis. Such samples, complemented with post-mortem samples from neurosurgical patients and parallel blood samples makes possible the identification of somatic mutations related to important neurosurgical conditions and investigation of their expression.

Assessment

Primary outcomes

Elucidate disease pathogenesis by identifying disease-causing, disease-susceptibility, and modifying genetic mutations.

Key secondary outcomes

Paired tissue and blood analysis can reveal the presence of somatic mutations that are important for pathogenesis.

Key inclusion criteria

1) Patients with established diagnosis of cerebrovascular disease and epilepsy and a control group (patients who were treated for conditions other than the target diseases) will be included in the analysis. If intrafamilial clustering or inherited disease is strongly suspected, and the importance and validity of linkage analysis are considered to be very high, family members (siblings, parents, children, other relatives etc.) will be included in the analysis of this study.
2) Patients who have visited an affiliated to the study hospital that was approved by the Ethics Committee to conduct the study.
3) Regardless of age or gender.
4) Adults who have given their written consent. Minors under 20 years of age or patients with cerebrovascular diseases and epilepsy who cannot be held legally responsible will require a consent of their parents or guardians.


Key exclusion criteria

Exclude cases where the above eligibility criteria are not met.

Other related information

The purpose of this study is to elucidate the pathogenesis of some most common neurosurgically treated diseases (cerebrovascular disorders, epilepsy) by identifying causative, disease susceptibility, and modifier genetic mutations.
The ability to obtain directly specimens of diseased intracranial and brain structures during neurosurgical operations for cerebrovascular disease and epilepsy is a unique opportunity to investigate these structures. Investigated together with parallel blood samples and collecting autopsy specimens can allow extensive genetic analysis for the presence of somatic mutations in potential causative relation to the investigated neurological diseases. In the cerebrovascular diseases domain, the main focus will be on cerebral aneurysms that lead to frequent disability and death after rupture, and cerebral arteriovenous malformations, which also often cause hemorrhage, epilepsy and ischemia.
