Why did they need to test the first degree relatives? I dont understand. If they have not inherited schizophrenia, why was they expecting there to be a difference? I mean they found out that there is not, but surely that is obvious.

For this kind of thing .

The present study tested the hypothesis that first‐degree relatives who are affected with BP would have a higher polygenic risk load of common risk variants in comparison to their relatives without BP, and that individuals at increased familial risk of BP would have a higher polygenic load of risk variants than control individuals. We tested this hypothesis using three cohorts:

It’s standard practice.

I dont know, maybe they are just confirming the obvious.

I’ve been fairly lucky when it comes to cognitive symptoms. I have some issues with focusing for long periods of time and an IQ test showed I have some minor difficulty in switching my attention from one task to another compared to the average person and have a somewhat slowed reaction time to things. But that’s it.

Cognition is a deceptive thing with me . Most people jump to the conclusion that because I/m very good verbally , then I must be very good in other areas of cognition . That couldn’t be further from the truth if one tried.
