Executive Function Diabetes Management: 8 Essential Skills for Neurodivergent Diabetics
- 2 days ago

As an ADHDer, I forget things on the reg. Left my phone downstairs (I think), no clue where my keys are so I guess I’m never leaving the house again, and I can’t for the life of me remember why I came into this room…
Forgetting gets a dangerous upgrade when it leaks into my diabetes management though. Whether that’s forgetting the insulin in the hotel refrigerator on vacation or forgetting to take my meds all together, my neurodivergent brain throws a wrench in my diabetes care routines all the time.
Surprisingly, I’m not alone.
In 2025, a survey of 1,150 insulin users across the US, UK, and Germany found that 59.6% missed at least one bolus dose in the past 30 days (Newson et al., Patient Preference and Adherence, 2025). The number one reason was forgetting.
Forgetfulness is a working memory failure. And working memory is one of EIGHT executive functions your diabetes care demands from you, every single day, with no PTO and no sick leave for relief. Nobody hands you this list, and your endo certainly doesn't screen for your neurodivergence at diagnosis. But when one of these functions is impaired (hi, it's me), specific and predictable things break, and they break in ways that get labeled as "noncompliance" instead of what they actually are: a brain being asked to run an operating system it’s not compatible with.
So here's the list. All eight of ‘em. What each one does, what breaks when it fails, and one accommodation per function that doesn't require you to become a different person entirely.
Diabetes management requires all 8 executive functions simultaneously. In a 2025 study of 173 adults with T1D, executive function explained 24% of self-management variance, and nearly 30% of participants scored above the clinical dysfunction threshold (Shanley et al., Journal of Health Psychology, 2025). The fix is reducing the cognitive demand on each function until your system survives a low-capacity day. Trying harder was never the solution.
Why Does Diabetes Management Tax Executive Function So Hard?
In 2025, a study of 173 adults with type 1 diabetes published in the Journal of Health Psychology found that stronger executive function significantly predicted better self-management, explaining 24% of the variance after controlling for demographics. Nearly 30% of participants (29.71%) scored above the clinical threshold for executive dysfunction (Shanley et al., 2025).
Read that again, boo. Almost one in three adults with diabetes is managing a 24/7 medical condition with a brain that clinically qualifies as executive-function impaired. If that's you, you are not an outlier. You're a third of the room (FOR ONCE).
Executive functions are the cognitive processes that turn intention into action: planning, remembering, starting, stopping, adapting. Diabetes is essentially an unpaid administrative job that runs on all of them at once (lucky us). Carb math requires working memory. Pre-bolusing requires time management. Supply reorders require task initiation and organization. Looking at a rough CGM graph without seriously spiraling requires emotional regulation.
And it stacks with the disease itself. In 2024, a meta-analysis of 12 studies found mean HbA1c runs 0.60 percentage points higher in people with T1D and ADHD, with substantially more DKA, hypoglycemia, and hospitalization (Dehnavi et al., Diabetes Research and Clinical Practice, 2024). High blood sugars impair cognition. Impaired cognition makes management harder. Harder management produces higher blood sugars. The loop feeds itself.
The 2025 ADA Standards of Care now formally recommend monitoring cognitive capacity throughout the lifespan for all people with diabetes (American Diabetes Association, Standards of Care in Diabetes, 2025). The clinical world is catching up to what you've been living. Slowly, but it’s happening.
Now let's name all eight of those pesky things.
1. Working Memory: The Thought That Doesn't Stick
Working memory holds information in your head long enough to act on it. Diabetes asks it to hold A LOT: you ate 45 minutes ago, your last correction of 2.5 units was at 2pm which means you probably have like 1.8 units still on board, and your infusion set tis on day three (you think?!)
What breaks is what clinicians call thought slippage. You think "I need to bolus." Then, one second later the thought is gone, and you move on with your day. Three hours later your CGM is screaming and you're genuinely confused about how this happened, again, when you knew you needed to bolus.
I once lost my train of thought mid-sentence while educating a patient about basal rates, and in the same moment realized I'd forgotten to pre-bolus for the lunch I ate twenty minutes earlier. I'm a CDCES. The knowledge was never the problem. The thought didn't stick because there was nothing to anchor it to.
The accommodation: Stop asking your brain to hold the thought. Anchor the bolus to a physical action instead: the coffee cup hitting the counter, sitting down at the table, unzipping the lunch bag. A behavior attached to something tangible or something you do regularly has much better survival odds than the free-floating intention in your brain.
2. Task Initiation: The Gap Between Knowing and Starting
Task initiation is the ability to start a task without a crisis forcing your hand, and it is by far my biggest ADHD kryptonite. I will frequently stare into the refrigerator, become overwhelmed by what’s in there, close the door and ignore what just happened, and then only decide to throw back a bowl of Fruity Pebbles when my blood sugar is bottoming out.
Diabetes asks for task initiation constantly: reorder supplies while you still have three sites left, call the pharmacy before the vial runs dry, open the app when the alert fires. In the 2025 Shanley study, task initiation showed the single strongest correlation of any executive function subdomain, at r = −0.416 with physical activity (p < 0.001). Initiation deficits weren't a minor player. They were the headliner. Lucky us.
ADHD makes future deadlines feel abstract until they're right in front of your face, and "I still have three infusion sets left" is not emergent enough to get the ball rolling.
The accommodation: Minimize the amount of tasks it takes to start the momentum of initiating the task. Think automatic refills from your mail-order pharmacy. Or my personal favorite: infusion sets in every room (you read that right) in a clear bin, so it is minimal movement for you to grab one when your pump runs out of insulin. The less steps involved, the less your brain is going to freak out about starting.
3. Self-Monitoring: Reading Your Own Body
Self-monitoring is noticing your own state of being: behavior, feelings, body signals. Diabetes assumes you'll notice you feel off, catch the slow-rising high, or register that it's been 12 hours since you checked your blood sugar.
It wasn’t until recently I found out that my AuDHD sister had trouble identifying how she feels and has no inner monologue going on in her brain. What must THAT silence be like?! But it also makes it difficult for her — and many other neurodivergent people — to self monitor.
There's a deeper layer here: interoception differences. Some autistic people genuinely cannot feel a high or a low the way textbooks describe. The body's built-in warning system is unreliable hardware. That's a sensing difference, and no amount of "what are you feeling in your body" fixes a signal that isn't arriving.
Not to mention, many people with long standing diabetes develop a degree of nerve damage which can contribute to making highs and lows difficult to feel as well.
The accommodation: Let technology be your interoception. A CGM is an external self-monitoring system, and that is a legitimate, clinically sound use of it. Set alert thresholds you'll actually respond to instead of ones so tight they become background noise.
4. Emotional Regulation: The Data-to-Spiral Pipeline
"You’re too sensitive!”
If I had a dime for every time I’ve heard this growing up — and as an adult — I’d be freaking rich. And also still unable to ask for help or express my feelings properly, but at least I'd be rich.
Emotional regulation is keeping your response proportional to the event. Diabetes hands you between dozens and hundreds of data points a day as if you’ve never been deeply traumatized by grades in school and perfectionist standards.
Emotional dysregulation can lead to things like rage bolusing: you see the high, you're MAD because you really tried to carb count that bowl of pasta, so you slam in a correction you know is too big, and you accept the future low as the price of feeling something happen NOW. You might also notice it as avoidance: you stop looking at the CGM entirely, because every number has started to feel like those SAT scores which are partially responsible for the inadequacy you now have to work through in therapy as an adult.
If you have Rejection Sensitivity Dysphoria (RSD), a "we'd like to see this trending down" from your endo, delivered in a perfectly neutral tone, can land like an indictment. Plenty of us have cried in the parking garage afterward. You're in good company, babe.
The accommodation: Data is information, not an indictment. Not a grade. If possible, widen your CGM alert ranges during high-stress periods so the alarms stop triggering you.
Try out this iOS shortcut I made. It shows you a brief love letter and let’s you take a breath before displaying your current blood sugar.
5. Flexible Thinking: When the Plan Breaks Down
Flexible thinking is adapting to changes in plans or your beliefs. Diabetes ignores your plan daily. You probably feel this most when the restaurant's carb count is unavailable online, the door knob rips your infusion set off right as your on your way out, and the meeting ran long and lunch is now at 2:30.
For autistic brains that rely on routine as infrastructure, a schedule disruption doesn't just inconvenience the system, it can take the whole thing down at once.
The accommodation: This one is a little more difficult to accomodate because it’s just the way the brain is set up. Write “if this, then that statements while your brain is calm: if a site fails, do this. If the carb count is unknowable, estimate with "usual, less, or more" logic and correct later. A decision made in advance is one your brain doesn't have to flex for in the moment.
6. Time Management: Dosing Lives in Time
Time management is estimating, tracking, and acting on time. Insulin is fundamentally a timing drug: pre-bolus 15 to 20 minutes before eating, know whether your last correction was two hours ago or four, and change the sensor before it expires at 2am.
Time blindness is the persistent difficulty in perceiving the passage of time and estimating how long tasks will take. In diabetes management, this is commonly manifested as seeing the alert to change your infusion set “soon” and not really understanding that soon should mean now if you’re about to leave the house.
The accommodation: Externalize time because your brain ‘aint gonna do it for you. I find timers best for this because I can see the countdown happening which makes more sense to me. So I’ll set a timer for when I need to start getting dressed, when I need to prebolus, when I need to begin eating, and when I need to be out the door. If alarms work for you, use those! It all depends on what helps your perception of time.
7. Impulse Control: The Pause Before the Action
When I was first diagnosed with ADHD, I was convinced impulsivity didn’t apply to me. That is, until I saw how it manifested in my diabetes management. Impulse control is the gap between urge and action. I’m a chronic rage bolus-er. If I’m not seeing my blood sugar come down expeditiously, I will be giving myself more insulin. Low blood sugar? Screw the rule of 15, I want to feel better NOW.
I want to be honest here, because the "eat 15 and wait 15" rule deserves scrutiny: waiting calmly for fifteen minutes while hypoglycemic assumes a regulated nervous system at the exact moment yours is least regulated. You don’t even need a neurodivergent brain to struggle with this one!
The accommodation: Automation removes the decisions that need the pause. Closed-loop AID systems handle correction timing math autonomously, which means there’s a little less room for rage bolusing (I said a little). For lows: pre-portioned treatments staged where you'll grab them, so the impulsive grab IS the correct amount.
8. Organization: The Stack That Has to Stay Standing
Organization is building and maintaining systems for stuff: supplies, information, logistics. Diabetes is a supply chain. Sites, sensors, insulin, strips, backup insulin, the backup meter, low treatments in the car, the travel kit.
What breaks: the backup insulin that expired in a drawer. The infusion set that wasn't in your bag the one day you needed it. The prescription that lapsed because the bottle was inside a cabinet, and out of sight is out of existence.
Supplies on the counter has been the single biggest system change for me. I know it looks cluttered. I've made peace with that, because visible supplies get used and hidden supplies get discovered after they expire. Decor is negotiable. DKA is not.
Neurodivergent organization is NOT going to look like the aesthetic Instagram systems you see in your doom scroll - it will probably look “messy.” AND THAT’S OK. We are looking for functional, not beautiful.
The accommodation: Change. Your. Environment, babe. Supplies live where your eyes naturally go: the counter, not the closet. One complete site-change kit in every bag you own. Let the environment hold the organization so your brain doesn't have to.
You probably are looking at the wrong thing when it comes to taking insulin
Here's the finding that should reshape how providers think about this. In the 2025 Shanley study, executive function did NOT significantly predict medication-taking (r = 0.076, p = 0.323) or cooperation with healthcare teams. It predicted eating behavior (r = −0.278), glucose monitoring (r = −0.161), and physical activity (r = −0.391).
Executive dysfunction doesn't primarily break the act of injecting. It breaks everything around it: the monitoring, the eating patterns, the movement, the supporting infrastructure that makes dosing decisions accurate.
So when a healthcare provider responds to a high A1c with "let's review how to take your insulin," it's reinforcing the behavior that was least likely to have been the issue. We gotta dig DEEPER. The leverage lives in the scaffolding, not the insulin pen.
This also explains a pattern I see clinically all the time: the client who never misses her basal insulin but hasn't looked at her CGM report in three weeks. Same brain, different executive function demands, but completely different break down points
So What Actually Reduces the Demand?
In 2025, a study in Diabetes Technology & Therapeutics found that teens with T1D and executive function challenges using insulin pumps had A1c averaging 0.65 percentage points lower than non-pump users, without increased DKA or severe hypoglycemia risk (Vitale et al., 2025). Automation accomplished what motivation could not, in the exact population where motivation gets blamed.
Three categories, in priority order:
Technology that automates, not technology that alerts. Closed-loop AID systems, automatic pharmacy refills, and CGM over fingersticks (when possible). An alert demands executive function at a random moment. Automation demands nothing.
Externalized memory. Physical staging, behavior-named alarms, bolus cues chained to objects and routines. Every item in this category is a job your brain no longer holds.
Simplified targets for low-capacity days. During hard periods, track one thing. Time in range or breakfast boluses only. A system you can run at 30% capacity beats a perfect system you abandon entirely.

Frequently Asked Questions
Which executive function matters most for diabetes management?
Task initiation showed the strongest single correlation in 2025 research (r = −0.416 with physical activity, Shanley et al., Journal of Health Psychology, 2025). But the honest answer is that it varies by person, neurotype, and which part of management keeps breaking. Map your own failure points first, then accommodate the function behind them.
Why do I keep forgetting to bolus even though I know better?
Because knowing was never the failure point. In 2025, 59.6% of insulin users reported missing at least one bolus in the past 30 days, and the top reason was forgetting (Newson et al., Patient Preference and Adherence, 2025). That's working memory failing under load, which is a mechanical problem with mechanical fixes: anchored cues, automation, staged supplies.
Does ADHD medication improve blood sugar control?
Not by itself, based on current evidence. A 2024 meta-analysis found no significant HbA1c difference between people with T1D and ADHD who received ADHD treatment and those who didn't (Dehnavi et al., Diabetes Research and Clinical Practice, 2024). Treatment can absolutely help your life. The glycemic gains seem to require system redesign alongside it.
Is executive dysfunction the same as low intelligence?
No, and the gap between the two is the entire story. Executive function is a set of management processes, separate from analytical intelligence. Nearly 30% of T1D adults in 2025 research scored above the EF dysfunction threshold (Shanley et al., 2025), and plenty of them are the hyper-researchers who know more about CGM data than their PCP. Knowing and doing run on different circuits.
How do I explain executive dysfunction to my diabetes care team?
Lead with the specific function and the specific failure: "Pre-bolusing fails for me because I lose track of time during work" gives your provider something actionable. The 2025 ADA Standards of Care now recommend monitoring cognitive capacity across the lifespan for all people with diabetes, so this is a clinically grounded conversation you have every right to start.
Phew. You've been running eight cognitive systems around the clock to stay alive, while being graded on the output and never told about the systems. That you're here, reading this, still managing, is not a small thing, friend.
Pick ONE function, and try its accommodation for two weeks. See how it feels and adjust as needed. You’ve got this.
