Aplasia of the right A1 segment + a prominent meningohypophyseal trunk

Hello,

I've found I have this about this 10~ years ago, and for a long time I've been wondering on how both affect me, both psychologically and physiologically, and I of course have even more questions...

Could these variations influence things like cognitive processing, mood regulation and others? What does the ACA supply blood to? What about the meningohypophyseal trunk?

How frequent should I have MRI/CT scans? And how much more am I at risk of a stroke and others because of my anomalies?

Thank you tons.
