Mr. Harris' memory has begun to exhibit signs of decline. Complicating matters is the knowledge that Mr. Harris's mother battled Alzheimer's disease.
Mr. and Mrs. Harris have met with Dr. Cohen about these concerns. She has administered a cognitive test, and requested some blood work and an MRI scan to exclude causes other than Alzheimer's.

Today, Mr. Harris, and his wife, Jen, are meeting with Dr. Cohen to talk about the test results and seek further insight and guidance.

Dr. Cohen: Mr. And Mrs. Harris, it's great to see you again. May I call you Jen and George? You were okay with that before?
Jen and George: Yes, of course.
Dr. Cohen: Yes? Okay. It's really good to see you. We were together a few weeks ago. We did some cognitive testing. You had some blood tests, and you had an MRI scan since I last saw you. So I want to go over all of those results, and then we can talk about next steps.
Dr. Cohen: How was the MRI?
George: Well, it's actually kind of noisy, you know, a little bit scary, you know, And you have to be like, really still, you know. So I had to go to the beach. I have to go somewhere or Hawaii or something.
Dr. Cohen: Yeah, you're picturing being on the beach. Good strategy. Good idea. You got through it. I'm glad.
Dr. Cohen: And I've got the results and we'll talk about that, okay?
Dr. Cohen: So just to recap how we got to this point, you had come to me not too long ago saying “something's going on with my memory. It's just not as reliable as it has been in the past. I'm still working.” You're in investments, correct?
George: Yes, yes.
Dr. Cohen: And you're still successful there and you're doing everything else for yourself, driving and shopping. And does he help with the cooking?
Jen: Yes, he does. He’s a good cook.
Dr. Cohen: Oh, he’s a good cook? Okay.
Dr. Cohen: So you're doing everything independently. And your sleep is good, your general health is good.
Dr. Cohen: And then you disclosed to me that mom had Alzheimer's- or we think it was Alzheimer's- in her seventies. So that sensitized you to the fact that there's something to check out here.
Dr. Cohen: So we did some cognitive testing together, and your score overall is quite good. You got 25 out of 30 on a test called the Montreal Cognitive Assessment- the MOCA for short- and that's a test of mild cognitive impairment.
Dr. Cohen: And it was just on the memory part of that that you had trouble. When we gave you five words, do you recall? And you were able to repeat them after me, but then after a distraction task, you could only come back with one of those five words. And that mirrors the memory problem you're noticing in day-to-day life.
Dr. Cohen: So I'm able to see what you're telling me about or what Jen's noticing. And the rest of the test, you did well. There's one other item that was tricky. It was copying a geometric figure. Do you remember that? The cube? It gave you some trouble?
George: Yeah. Yeah, it kind of- it gave me a little bit of trouble.
Dr. Cohen: Yeah. The perspective and the angles were a little wonky, so you lost a point on that. It's not, you know, a make-or-break thing. It just, again, gives us a little bit of a window into how the brain is working. But mainly it was the memory part that is telling me, ‘Yes, there is something going on’. You're noticing it. I can see it.
Dr. Cohen: We call this mild cognitive impairment- that's the syndrome diagnosis. But we need to dig deeper. What's causing it? Because I'm telling you what you already know- there's mild memory impairment- but this term, ‘mild cognitive impairment’, really refers to memory impairment or cognitive impairment while people are still functioning well and independently.
Dr. Cohen: So that that's you, as opposed to dementia, where people are no longer independent in all activities. So you did some blood work because we wanted to rule out things like thyroid disease or other things we can see in the blood that could cause memory problems.
Dr. Cohen: Your blood work is beautiful. That's good. So there's no deficiencies of any kind. B12 levels- good. As I said, the thyroid level, the cell counts, kidneys are functioning- all that's good. So, nice to have normal blood work. But we still need an answer. What's causing the memory problem?
Dr. CohenThen we did the MRI scan. And the MRI scan is nice. It's good. The structure of the brain looks good.
Jen: Good.
Dr. Cohen: That's a relief.
Dr. Cohen: No strokes, no tumors, no scars in the brain. Yeah. So, yeah, we want good news. We don't want to have tumors and strokes. That's good.
Dr. Cohen: No strokes, no tumors, no scars in the brain. Yeah. So, yeah, we want good news. We don't want to have tumors and strokes. That's good.
Dr. Cohen: But it's still not showing us that memory problem. And it still leaves open the possibility that Alzheimer's disease may be creeping up. And we want to rule that out, or be clear about whether that's what we're dealing with.
Dr. Cohen: So the next step to get greater confirmation on the diagnosis would be to send you for a scan called a PET scan. Okay? If you're willing to put up with another scan, it's not a noisy scan this time. It's not as tight or claustrophobic, but it is a scan. And it will give us a much clearer idea about specifically whether amyloid plaque is building up in the brain.
Dr. Cohen: And amyloid is a protein that starts accumulating in the brain very early in people who are developing Alzheimer's- even before symptoms. So it's a very, very early warning of Alzheimer's, and it's helpful to be clear about the diagnosis, because then that's the gateway to ‘how do we manage it, what do we do? How do we plan for the future? What treatments are relevant?’
Dr. Cohen: So if you're willing to go for this PET scan, that will give us good information to go forward with next steps. Does that sound okay?
George: Yeah. Yeah, it does. That sounds good.

Mr. Harris completed the additional PET scan. Dr. Cohen requested. He and his wife now return to see the doctor and discuss the results of his full diagnostic evaluation.

Dr. Cohen: George, Jen, great to see you again. Very glad to see you.
Dr. Cohen: So just to recap, we're here to talk about the PET scan results, and we talked about the fact that you have mild cognitive impairment. The MRI and the bloodwork weren't showing us the cause. We wanted to dig deeper and see “is this Alzheimer's disease?” So that's what we're here to talk about.
Dr. Cohen: So the PET scan does show this protein amyloid accumulating. And I know that's not what we were hoping for, but it is the reality that amyloid plaque is developing in the brain. And amyloid is that early, early change of Alzheimer's disease.
Dr. Cohen: So how are you doing with that now?
George: You know, I'm I was really hoping that there would be a different reason.
Dr. Cohen: That's very understandable.
George: But yeah, I had a feeling.
Dr. Cohen: You kind of felt that if it might show Alzheimer's and yet, of course, we're hoping for something else.
George: Yeah. Yeah. This- it's going to be- it's going to be difficult for me. You know- I don't want to forget about my kids. I don't want to forget about my grandkids.
Dr. Cohen: Of course, family is important and our memories are precious. Yeah.
Dr. Cohen: You know, this is a tough disease, Alzheimer's. But again, you've caught it early. And you're doing well day to day. The disease brings this cloud over your head. But our job now is to say, “let's live well, despite Alzheimer's”.
Dr. Cohen: Now that we know what this is, we could talk about treatment options, which we wouldn't be able to talk about very sensibly without having a diagnosis.
Dr. Cohen: And that's going to be important. And let's talk about, you know, bringing the family into the mix.
George: Yeah.
Dr. Cohen: Fortunately, as I said, you've caught this early, that gives us the best chance to try and keep this stable.
Dr. Cohen: When we talk about Alzheimer's disease, people often think right away of someone very disabled. Right. And they don't realize this is a very slowly progressive disease that starts almost imperceptibly. You know, where does normal aging end and Alzheimer's begin? A little bit of forgetfulness... You know, this is the very early, early stage.
Dr. Cohen: And we don't want him to feel less capable than he is. He's very capable. But we do also not want to ignore the diagnosis. So we'll talk more about the treatments that are possible. Okay. Okay. And I'll look forward to that detailed conversation. And you can decide if you want to bring your children in to join us. Okay?
Jen: Okay.
George: All right. Sounds good, Doctor.
Dr. Cohen: Okay. So, good to speak with you. And to be continued. Okay.
George: Thank you.
Dr. Cohen: You’re welcome.
