Remembering appointments, medicines, and things you meant to do
Use reminders, cues and simple records to keep plans on track after a brain injury
You meant to call the insurance company back. You meant to pick up the prescription on the way home. Both things mattered to you. The intention just did not come back at the right moment.
Problems with this kind of memory are common after a brain injury [1]. These slips can feel more upsetting than forgetting a name, because the cost shows up as missed appointments, late bills or doses of medicine that were skipped or doubled.
Reminders and cues that come from outside your head have helped people in studies. This guide covers how future plans slip, which cues tend to work, and how to build safe routines for medicines with your pharmacist.
Why remembering to do things is its own kind of memory
Researchers call it prospective memory, which means remembering to act on an intention at the right moment in the future [2]. Examples include keeping an appointment, calling someone back or taking a medicine each morning [3, 2]. The Model Systems Knowledge Translation Center (MSKTC), which produces federally funded TBI factsheets, calls this “remembering to remember” [3].
Why it slips after a brain injury
To act on a plan later, you need to hold the plan, notice the right moment, and then switch away from what you are doing. A brain injury can disrupt any of those steps. A 2018 review looked at 84 studies of adults with acquired brain injury. Its most consistent finding was that time based tasks are harder than event based tasks [1]. A time based task depends on the clock, such as a call you must make at 2 in the afternoon. An event based task is set off by something that happens, such as picking up a refill when you pass the pharmacy.
The review notes that “I forget to take my medicine” is among the most frequent memory complaints from survivors [1]. Problems with prospective memory can affect independent living, keeping social plans and holding a job [2].
Who the research covers
Most studies in this area involved people with moderate to severe brain injury. The 2018 review found only two studies focused on mild injury [1]. Still, the same practical tools are offered to people with concussion. Canada’s Living Concussion Guidelines, written for adults whose symptoms linger, list self directed strategies that include outside aids and changes to your surroundings [4].
Turning "later" into a cue you cannot miss
The core idea is simple: arrange for something outside your head to bring the plan back at the right moment.
Comparison compiled by Safety Behind the Wheel Foundation
Types of cues for future tasks
| Cue type | Example | Works well for |
|---|---|---|
| Timed alarm or phone alert | An 8 a.m. alert to take morning pills | Fixed times, medicines |
| Event or routine cue | Pills sit next to the coffee maker | Daily habits |
| Place cue | Library book left in front of the door | Things to take with you |
| Written list or checklist | Errand list on the car seat | Several steps or stops |
| Reminder from a service or person | Text the day before an appointment | Appointments, one time tasks |

Timed reminders
Reminders that arrive at a set time can help a lot. A large British trial sent pager reminders to 143 people aged 8 to 83, most of whom had a head injury from trauma or a stroke. Over 80% of those who completed it handled everyday tasks significantly better while they had the pager. For most, the gains lasted 7 weeks after the pager went back [6].
Phones do the same job today. INCOG 2.0, a 2023 international guideline for memory rehabilitation after TBI, prefers electronic reminders such as smartphones [7]. The 2018 review also describes a small phone study in people with TBI. Most of them (10 of 13) found that an alarm sound and an on screen message helped them keep appointments and finish tasks [1].
Make your reminders specific. A one word alert is easy to dismiss. “Take blue pill with breakfast, then check the box” tells you exactly what to do.
Event cues and place cues
Because clock based tasks are harder, rehabilitation programs teach people to turn them into event based tasks that come with a built in cue [2]. Instead of trying to recall a 9 p.m. dose, you keep the evening pill box beside your toothbrush. Brushing your teeth now prompts the dose.
Place cues work the same way. Put the item you need where you will trip over it. Hang the bag of returns on the front door handle. Leave the lunch you need to pack on top of your car keys.
Brief random check ins
One idea from research uses prompts with no task attached. In a study summarized in the 2018 review, 20 people with brain injury got a text that just said “stop” at random times in the day. On those days, they did better at carrying out planned tasks [1].
What about “if, then” plans?
Many people make “if, then” plans, such as deciding that when they sit down to dinner, they will take their evening pills. Researchers call these implementation intentions. The method has shown promise in other groups. In a study of people with TBI, though, it did not improve performance [1]. The 2018 review suggests it may depend on self monitoring skills that injury can weaken [1]. Pair any plan like this with an outside cue.
Keeping appointments
Appointments are classic time based tasks, often weeks away. That makes them easy to lose.
Capture it on the spot
Enter an appointment into your calendar before you leave the desk or hang up the phone. If that is hard, ask the receptionist to write it on a card, then add it to your calendar that day. Phones offer alarms, task reminders and voice entry, so you can speak the details if typing is slow [8].
Use layered reminders
One alert is easy to swipe away. Set two: one the day before, so you can plan travel, and one with enough time to get ready and leave. Ask the clinic whether it can send a reminder text or call.
Plan the trip as well as the time
Add the address, travel time and anything to bring, such as an insurance card or your medicine list. Use the notes field of the calendar entry to collect questions for the visit as they occur to you, so they are ready when you walk in. If memory or attention problems make you unsure about driving, arrange a ride and raise it with your care team. Losing track of a route while your mind is busy with other plans is a safety risk on the road.
Building a safe medicine routine
Medicines are where slips can matter most, since a skipped or doubled dose may affect your treatment or your safety. The MSKTC lists missed or mistimed medicines among common memory problems after TBI [3]. Work out your routine with your prescriber and pharmacist, and do not change how you take any medicine on your own.
Pill organizers and dispensers
A weekly pill organizer is the most common tool. MedlinePlus, a consumer health site run by the National Library of Medicine, suggests filling it for 7 days and labeling each compartment with the time of day. It also suggests asking your pharmacist which organizer fits your medicines best [9]. Automatic dispensers with a blinking light and an alarm are another option. A trusted friend, relative or pharmacist can fill them [9].
Ask your pharmacist whether other packaging options might suit you, such as doses grouped by time of day.
When your medicines change
Each time a prescriber adds, stops or changes a medicine, update your list and your organizer that same day. The FDA suggests telling your pharmacist about every medicine you use and any you have stopped, especially if you fill prescriptions at more than one pharmacy [10]. The MedlinePlus caregiver guide suggests going over any differences between your list and your provider’s list [5]. If a new schedule is confusing, ask the pharmacist to write it out step by step.
Link doses to daily events
The National Institute on Aging notes that some people tie doses to meals or bedtime, while others rely on charts, calendars, weekly pill boxes or timers [11]. A caregiver guide from MedlinePlus suggests using a watch alarm or phone notification for doses that fall between meals [5]. Phones also offer apps built for medicine reminders [8].
Keep one up to date medicine list
Write down every medicine you take, including those bought without a prescription. The National Institute on Aging suggests keeping one copy at home and one in your wallet [11]. The Food and Drug Administration (FDA) encourages people to keep a record of their medicines and give it to their pharmacist [10]. Bring the list to every appointment, and ask whether each medicine is still needed [5].
Records of what you have already done
A second problem often follows the first. Once you have done something, you may not remember doing it. That can lead to double doses, paying a bill twice or driving back to check the stove.
Make finished tasks visible
The MSKTC suggests using checklists to track what you have done and the steps in a task [3]. A pill organizer works as a record too: an empty slot means the dose is taken. MedlinePlus suggests a medicine list with a place to check off each dose as you take it [9].
Other simple records include:
- A check mark or time written next to each item on today’s list.
- A quick phone photo of the locked door or the switched off stove.
- A note in your calendar when a bill is paid, with the amount and confirmation number.
- A sticky note on the dog food bin with the date and feeding time.
Close the loop right away
Mark a task done the moment you finish, before you move on. If you wait, the mark may never happen. When a task is only half done, such as a message started but not sent, leave yourself a note saying where you stopped.
What rehabilitation programs teach
Therapists can help you set up and practice these tools. A randomized trial enrolled 45 adults with moderate to severe TBI living in the community, on average about 9 months after injury. Each person had eight weekly sessions. Groups whose sessions trained diary use and time management improved more on a prospective memory test. They used their diaries more in daily life [12]. Relatives’ ratings of everyday memory slips, however, did not change significantly. The study had no long term follow up [12].
Newer programs add training in self monitoring, so people learn to notice and correct their own slips [2]. INCOG 2.0 also recommends devices that prompt each step of a complex task [7].
How family can help
Family members help most when they point you to your cues and let you act. Asking what your list says, instead of giving the answer, keeps you in charge of the task. In the first weeks, a partner or friend can remind you to check your list. The MSKTC notes that strategies like this can become habits you manage yourself [3]. Agree ahead of time on how and when someone will remind you, so prompts feel like teamwork.
The evidence has limits. The 2018 review found that many studies were single cases or very small. Only three were randomized controlled trials [1]. Most of the work so far has tested compensatory strategies [1].
A composite example
Imagine a 51 year old woman recovering from a moderate TBI after a highway crash. She kept skipping her evening medicine and twice took her morning pills again by mistake. With her pharmacist, she set up a weekly organizer kept beside the coffee maker. A phone alarm at dinner reminds her to take the evening pills and check the box. Her partner fills the organizer each Sunday while she watches and names each medicine. After a month, the missed and repeat doses have stopped.
A daily checklist for future tasks
Checklist from Safety Behind the Wheel Foundation
- Check today’s calendar at breakfast.
- Take morning medicines from the organizer and check the box.
- Put anything you need to take with you by the door.
- Look at the list again at lunch.
- Mark each finished task with a check and the time.
- Take evening medicines when the alarm sounds, then check the box.
- Before bed, review tomorrow and set any new alarms.
Questions to ask your care team
Question checklist from Safety Behind the Wheel Foundation
- Is remembering to do things later a specific problem for me, and how can we measure it?
- Which reminder tools would suit my injury and my daily routine?
- Could a therapist help me set up and practice a reminder system?
- Can my pharmacist help me choose a pill organizer or packaging that fits my medicines?
- If I skip a dose of one of my medicines by mistake, what is the plan?
- What should I do if I am not sure whether I already took a dose?
- Are all of my current medicines still needed?
- Might one of my medicines be adding to my memory problems?
- Should my memory for appointments and tasks be checked before I return to driving or work?
Frequently asked questions
Why can I remember facts but not what I meant to do?
Remembering to act at the right moment is a distinct skill. Research in brain injury finds that tasks tied to a time are harder than tasks tied to an event [1]. Linking a task to a cue you will meet anyway can help.
Are phone alarms really enough?
They help many people. Most people in one small TBI study found phone alerts helpful, though 5 of the 13 worried about depending on the phone [1]. A paper backup for the most important items is wise.
Can my family manage my medicines for me?
They can help. MedlinePlus notes that a trusted friend, relative or pharmacist can fill a pill dispenser [9]. Watching while they fill it, and checking off doses yourself, keeps you involved.
The bottom line
Recommendation from Safety Behind the Wheel Foundation
Remembering to do things later is a skill that a brain injury often disrupts, and outside cues are the most practical fix. Use timed alerts, tie tasks to daily events and places, and keep a visible record of what you have already done.
For medicines, build your routine with your pharmacist and prescriber, keep one current list, and never take an extra dose because you are unsure.
