Multiple lacunar infarcts

I’m 57yo. I have multiple sclerosis and was having several new symptoms so back in 2021 I went to a neurologist I had seen in 2016 and had a follow up MRI. Now, prior to this appointment I had only been diagnosed with MS. At my follow up appointment, this neurologist nonchalantly told me that my MS was stable. Great news but I also had 4 lacunar infarcts and a meningioma in a not so great location. That’s it, no further conversation. My brain tumor is what I decided to focus on following this little surprise. That’s a whole different horrible story. Now my mind is turning to the lacunar infarcts and obvious concerns with them. My cognitive function has declined since my craniotomy. I’m an RN but I wouldn’t trust myself to work with patients now. Is this due to my craniotomy? My remaining brain tumor? My MS? More likely the 4 lacunar infarcts. I’m very frustrated with my health care providers. I’m very concerned about my future health yet none of my providers are. I hope I can get some advice from this group!
I do have an MRI scheduled in December to monitor my brain tumor; hopefully there aren’t any more lacunae.
