Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The authors submitted a research paper in which they reported the results of the longitudinal genome-wide association study for the first time to identify genetic modifications associated with cognitive defection after subarachnoid hemorrhage. They established genotype difference in the rs76507772 SNP for  developing incidental events of the cognitive impairment after SAH. Yet, they identified 5 SNPs including rs138753053, rs56823384, rs145397166, rs10503670, and rs76507772, which were significantly associated with cognitive impairment in patients with APOE É›3/É›3. The findings seem to be impressive and having serious clinical significance. However, I would like to make some comments to discuss them.

1. Although GWAS technology allows to identify loci in individuals at high risk, there is a problematic issue whether genetic predictive score is sufficient tool for reclassification of the CVD and cerebrovascular disease individuals. Please, discuss the issue taking into consideration current clinical guideline for CVD prevention of ESC

2. Please, link polygenic risk assessment with additional economic burden and rpovid your opinion on it.

Reviewer 2 Report

Comments and Suggestions for Authors    

In this study, the researchers investigated genetic factors associated with cognitive impairment following subarachnoid hemorrhage (SAH). Conducted on 153 SAH patients, the study identified five significant genetic loci linked to cognitive decline. A weighted polygenic risk score based on these loci predicted cognitive impairment with an AUROC of 0.745. This study may suggest new genetic markers that could help predict and manage cognitive outcomes in SAH patients.

1. The tables are very difficult to read. They should be reformatted.

2. The results of APOE É› alleles are contradictory throughout the manuscript and should be revised.

3. The discussion is confusing and loose. Most of it seems to me irrelevant.

 

Comments on the Quality of English Language

The language of the manuscript should be revised.
