I've posted before about having chemo brain, which can last years. I was previously least concerned about being unable to "find words", but now it's the symptom that bothers me the most, almost distressingly, as its frequency of occurrence has increased greatly.
Everybody has that experience of forgetting a word once in a while, when it's on the tip of your tongue but you just can't come up with it. This happens to me literally every day, multiple times a day. In fact, I'd say it happens any time I have any kind of conversation that goes beyond a few sentences. People with whom I'm speaking will generally graciously ignore my verbal bumbling, or chalk it up to aging, but I know a lot of people my age and older and the extent to which I can't produce the words I want is simply not typical.
My husband agrees that I am "not finding words" much more often compared to a few years ago, and I sometimes wonder if getting covid in December 2022 could have exacerbated the problem.
Recently, another possible factor has come to my attention. When I had both my ovaries removed, I knew that "increased risk of dementia and other changes in mental function" were possible, though my OB/GYN dismissed that particular concern based on lack of evidence, especially when weighed against the more immediate risks of breast cancer recurrence or ovarian cancer.
Now, a new study has come out connecting bilateral oophorectomy with reduced white matter in the brain. The article refers to other research that "found that patients who've had both of their ovaries removed before they hit menopause face a higher risk of cognitive impairment and dementia later in life."
But how much later? Is it possible that early signs of cognitive impairment might show up within a couple years? I got my ovaries out in June 2022, which means my post-oophorectomy period basically overlaps with my post-covid period. Might either or both these events have been a contributing factor to my increased inability to find words?
Yet another consideration is my hormone therapy, which completely eliminates estrogen in my body. There's a lot going on between estrogen and the brain, and lots of research that studies it. I started taking an aromatase inhibitor right after finishing chemo, so again, those potential causes overlap, and also wouldn't explain the worsening of symptoms. Still, it probably doesn't help that one study found, "A pattern of decline in working memory and concentration with initial exposure to anastrozole was observed," with a caveat saying, "The longer term (> 18 months) effects of anastrozole on cognitive function remain to be determined." I am holding out just a little bit of hope that maybe I'll see some kind of improvement when I stop anastrozole in about 5 years.
Who knows. Without formal cognitive testing, including baselines, I'll never know for sure what's going on. It's just something I've been thinking about lately.
Suffice it to say, my medical history includes multiple things that could have negatively affected my brain function in very noticeable ways. It's just one more reason for me to continue to be covid-cautious; I can't do anything about having had chemo or a bilateral oophorectomy, and I choose to continue with anastrozole to help prevent cancer recurrence, but since every covid infection carries a risk of damage to the brain, I can try to preserve what brain function I have left by trying not to get covid again (by masking indoors, avoiding crowds, staying up-to-date with vaccinations, rapid testing before gatherings, meeting others outdoors when possible, using air purifiers and promoting ventilation with open windows where possible, monitoring wastewater data and staying informed, i.e., the type of things recommended by Yale School of Public Health).
