Taking medication as prescribed sounds simple in theory. In practice, it can be one of the more difficult parts of managing a neurological condition, especially alongside fatigue, brain fog, a changing daily schedule, or several medications with different timing requirements. This is not a reflection of effort or discipline. According to the World Health Organization, adherence to long-term medication regimens averages only around 50 percent among patients with chronic diseases in developed countries, and even lower in developing countries (WHO, 2003). In other words, missed or mistimed doses are common.
For people living with a neurological condition, and for the caregivers supporting them, medication routines often carry a bit more weight, since timing and consistency can be closely tied to symptom control. Understanding why routines slip, and having a few practical strategies on hand, can make this part of daily life noticeably more manageable.
Why medication routines can be hard to maintain
Several overlapping factors tend to make medication routines harder to sustain.
Fatigue and brain fog, whether related to the condition itself or to side effects of the medication, can make it difficult to remember whether a dose was taken, particularly for people managing more than one medication at a time. In epilepsy specifically, cognitive side effects such as difficulty concentrating or memory changes are a recognized possibility with some seizure medications, and up to 40 percent of people with epilepsy report some form of cognitive challenge (Epilepsy Foundation; PMC). In Parkinson's, fatigue is one of the most commonly reported symptoms and can affect the mental energy needed to stay on top of a routine (Parkinson's Foundation).
Changing schedules and daily disruptions play a role too. Travel, illness, work, or simply an unpredictable day can interrupt an otherwise steady routine, and research indicates that these kinds of disruptions are associated with a higher likelihood of missed doses (PMC).
A systematic review of studies on antiseizure medication adherence found that forgetfulness was the most frequently cited barrier, reported by nearly half of respondents, followed by side effects and a perceived lack of effectiveness (Neurology Clinical Practice; PMC). Nonadherence rates among people with epilepsy have been estimated at roughly 29 to 60 percent depending on the study and measurement method used (PMC). In addition, timing sensitivity can matter more for some neurological conditions than others. In Parkinson's, medications such as levodopa are typically short-acting, and research suggests that even a delay of around 30 minutes can be enough for motor symptoms to reemerge as the previous dose wears off (Parkinson's Foundation). This means the margin for a missed or delayed dose can feel narrower than with some other types of medication.
Connecting medication with existing routines
One approach that appears to help is linking medication to something that already happens reliably each day, sometimes called habit stacking. The idea is that an established habit, such as brushing your teeth or making coffee, can act as a dependable cue for a new one. Research on habit formation suggests that repeated pairing of a medication with a stable daily cue can gradually make taking it feel more automatic and less reliant on memory alone (PMC, 2024).
The Epilepsy Foundation suggests a similar approach: setting a plan to take medication at the same time each day, ideally alongside another consistent activity (Epilepsy Foundation). For Parkinson's, where timing precision matters more, some clinicians recommend structuring medication around meals specifically, since high-protein foods can affect how well levodopa is absorbed, so doses are sometimes best taken 30 to 60 minutes before eating or about an hour afterwards (Parkinson's Foundation).
Using reminders, diaries, and medication lists
Reminders can help close the gap that memory alone sometimes cannot. A 2020 meta-analysis of randomized trials found that mobile medication reminder apps were associated with a meaningful improvement in adherence (PMC). Beyond apps, the Epilepsy Foundation suggests a few low-tech options as well: keeping medication somewhere visible, like next to a coffee machine or toothbrush, using a weekly pillbox and checking it daily, and setting a phone reminder about a week before a prescription is due to run out (Epilepsy Foundation). For Parkinson's, similar strategies apply, along with options like pharmacy-prepared blister packs organized by day and time (Parkinson's Foundation).
Diaries can add another layer of useful detail, particularly around symptoms. For Parkinson's, a symptom diary that notes when "off" periods occur in relation to dose timing, meals, or stress can help identify patterns worth discussing with a clinician (Parkinson's Foundation). In epilepsy, a similar log connecting seizure activity to medication timing or missed doses can serve the same purpose.
An up-to-date medication list is worth keeping on hand as well, not only for daily use but for medical visits. The CDC recommends bringing a current list of medications, vitamins, and supplements to any healthcare appointment, and updating it whenever something changes (CDC).
For people living with epilepsy, tools like this are increasingly built directly into the apps that support daily monitoring. The My Diary feature in EpiMonitor by Empatica, for example, lets users log seizures alongside details such as rescue medication taken, triggers, and mood, all in one place alongside sleep and activity data, so this information is on hand for both day-to-day tracking and available as a downloadable report for clinician conversations. We are also excited to share that similar tools designed specifically for the Parkinson's community are currently in development.
How caregivers can help
Caregivers frequently take on a significant share of medication management. According to a Caregiver Action Network survey, about 70 percent of caregivers report being responsible for managing a loved one's medications (Caregiver Action Network). This can include organizing pillboxes, coordinating refills, tracking side effects, and helping notice patterns that the person themselves may not always catch, particularly during periods of fatigue or cognitive difficulty.
That said, involving a caregiver works best as a partnership rather than something done entirely on someone's behalf. Keeping the person living with the condition involved in decisions about their own medication, where possible, tends to support both adherence and a sense of independence. Caregivers can also play a useful role in appointments, helping recall details about missed doses, side effects, or symptom changes that might otherwise be difficult to remember in the moment.
What information to bring to an appointment
A little preparation can make medication-related conversations with a clinician considerably more productive. It is generally useful to bring:
- A current medication list, including dosages and times, plus any vitamins or supplements
- A record of missed or delayed doses, if this has been happening, along with any pattern you have noticed
- Any side effects, even ones that seem minor or unrelated
- A symptom or seizure diary, if you keep one, especially noting timing relative to doses
- Questions about timing, such as whether a dose can be adjusted around meals, sleep, or other medications
Bringing this information along, even in a simple written or app-based format, gives a clinician something concrete to work from, rather than relying on memory during a short appointment window.
In summary
Medication routines are rarely difficult because someone is not trying hard enough. Fatigue, brain fog, complex schedules, and the sheer number of moving parts involved in managing a neurological condition all make consistency genuinely challenging, and this holds true across conditions like epilepsy and Parkinson's. Connecting medication to existing habits, using reminders and diaries, involving a caregiver where helpful, and bringing clear information to appointments can help reduce how much of the routine depends on memory alone.
