Executive functions and Parkinson's: practical exercises to preserve them
Parkinson's disease affects executive functions from early stages — planning, flexibility, inhibition, working memory, attention. This program of 20 targeted exercises, adapted to the specifics of Parkinson's, helps preserve them and maintain autonomy longer.
Parkinson's disease is known for its motor symptoms — tremors, rigidity, bradykinesia. But beyond the motor picture, another neuropsychological terrain gradually erodes, often silently: executive functions. These high-level abilities — planning a sequence of actions, adapting when rules change, resisting an impulse, maintaining multiple pieces of information in mind simultaneously — are precisely those upon which daily autonomy depends. Preparing in the morning, managing medications, cooking a meal, managing one's schedule: all these activities mobilize executive functions. This guide offers a program of 20 practical exercises organized by executive function, specifically designed for the constraints of Parkinson's disease — adapted to on/off fluctuations, accessible despite motor symptoms, and progressive to follow each patient's evolution.
1. Executive functions in Parkinson's disease
1.1 Why Parkinson's specifically affects executive functions
Executive functions (EF) are primarily underpinned by the prefrontal cortex and its connections with the basal ganglia — the central gray nuclei at the heart of Parkinsonian pathology. Parkinson's disease causes dopaminergic depletion in the nigrostriatal circuits that govern not only motor control but also the frontostriatal loops involved in EF. From the early stages of the disease, even before motor disorders become disabling, subtle deficits in executive functions can be detected by sensitive neuropsychological tests.
These Parkinsonian executive deficits have a characteristic profile: they primarily affect cognitive flexibility (difficulty in changing strategy or adapting to new rules), verbal fluency (notably generation fluency), planning (difficulty organizing complex action sequences), and working memory (reducing the ability to maintain and manipulate multiple pieces of information simultaneously). These deficits are distinct from those observed in Alzheimer's disease — where episodic memory is primarily affected — which explains why people with Parkinson's may have difficulty planning a trip while perfectly remembering their last birthday.

1.2 The clinical picture: how executive deficits manifest in daily life
Parkinsonian executive deficits do not always manifest obviously during ordinary conversation — which is why they are often underestimated by the patients themselves and by those around them. They become apparent during tasks that require complex organization, rapid adaptation, or simultaneous management of multiple pieces of information.
| Executive function | Deficit in Parkinson's | Daily manifestation | Impact on autonomy |
|---|---|---|---|
| Planning | Moderate to severe | Difficulty organizing a sequence of actions (recipe, route), forgetting steps | Cooking, managing medications, preparing outings |
| Cognitive flexibility | Affected early | Perseveration on a strategy even when it no longer works, difficulty changing topics or tasks | Adapting to unforeseen events, social conversations, driving |
| Inhibition | Variable | Tendency to complete automatic movements (paradoxical freeze), impulsive responses, difficulty ignoring distractors | Safety at home, managing impulsive purchases, conversations |
| Working memory | Moderate | Loses track of a conversation, forgets what they were doing when moving from one room to another, difficulty doing two things at once | Dual tasking, managing the agenda, following conversations |
| Divided attention | Affected early | Marked difficulties sharing attention between two simultaneous tasks — particularly the dual task of walking + talking | Safety while walking, cooking, conversation during an activity |
1.3 The dual task: a specific challenge of Parkinson's
One of the most specific and well-documented manifestations of executive deficits in Parkinson's is the difficulty with dual tasks — performing two activities simultaneously. A well-known phenomenon among clinicians is the deterioration of walking when the patient talks at the same time: the conversation absorbs attentional resources that should be available for the automatic regulation of walking, leading to slowing, instability, or even freezing. This is not ordinary distraction — it is a direct manifestation of the frontal executive deficit in managing limited attentional resources.
This peculiarity has an important implication for the exercise program: stimulating EF in Parkinson's patients must include progressive dual task exercises, but always ensuring physical safety — never during fast walking or on uneven terrain in moderate or advanced stages.
🧠 Parkinson's specificity: Unlike general cognitive stimulation programs, a specific program for Parkinson's must systematically take into account the on/off windows of dopaminergic treatment. The most cognitively demanding exercises (flexibility, inhibition, dual task) should be planned during "on" phases — that is, 30 to 90 minutes after taking medication. Softer exercises (simple planning, autobiographical anchoring) can be practiced during periods of lower treatment effectiveness.
2. Program of 20 exercises by executive function
FE 1 — Sequential Planning
Organize a sequence of actions to achieve a goal · Exercises 1–4Planning the Day in Time Slots
Every morning, plan the day by noting 4 to 6 activities with their estimated time and optimal order. At the end of the day, compare plan and realization: what was modified? Why? This meta-planning reflection strengthens the prefrontal circuits of planning while remaining close to real life.
Simplified Tower of Hanoi
Version with 3 disks of the classic game (available in physical version or free app): move all disks from one peg to another while respecting the rule (never a large disk on a small one). Requires planning of at least 7 moves. Start with 3 disks, aim for 4. Excellent tree planning exercise.
Imaginary Route
Choose a known route (going to the pharmacy, to the market) and plan it verbally out loud in the exact order: starting points, route, stops, order of purchases to optimize the journey, return. Then repeat with a less familiar route. Strengthens spatial and sequential planning.
Mental Recipe
Choose a familiar recipe and mentally reconstruct all the steps in the exact order — with the ingredients, durations, order of using the equipment. Then check with the actual recipe. Difficult variant: plan two simultaneous dishes while managing overlapping cooking times. Very close to the daily requirements of autonomy.
FE 2 — Cognitive Flexibility
Adapting when the rules change · Exercises 5–8Alternating Sorting Task (Simplified DCCS)
Sort image cards by color for 2 minutes, then change the rule (sort by shape, or by the number of items) on signal. The exercise is difficult not because of the rules themselves, but because of the need to inhibit the previous rule. Repeat the alternation 4 to 6 times during the session.
Alternating News Reading
Read a newspaper article, then immediately give the opposite opinion orally to that expressed in the article. This perspective reversal exercise engages cognitive flexibility and theory of mind. Start with neutral topics (sports, culture), progress to more complex topics (politics, society).
Fluency by Alternating Categories
Name alternately an animal, then a piece of furniture, then an animal, then a piece of furniture (etc.) for 3 minutes. The alternation constraint — changing category with each item — directly tests cognitive flexibility and verbal fluency, both affected in Parkinson's. Difficult variant: 3 categories in rotation.
Contextual Opposites Game
Give the antonym of randomly presented words (fast/slow, big/small) — easy exercise. Then reverse: each time a word is presented, give a synonym EXCEPT for color words (give the antonym). This change of contextual rule mimics daily challenges of adapting to changing rules.
FE 3 — Inhibition and response control
Resist an automatic response · Exercises 9–12Simplified oral Stroop
The adult presents color words written in a different ink (the word "RED" written in blue). The patient must name the color of the ink — not the written word. Resisting the impulse to read the word is the main difficulty. Start slowly, without time constraints, progressing to a faster pace.
Vocal Stop-and-Go
The patient recites the days of the week or the months. On signal (hand raised or noise), they stop immediately. On a second signal, they resume where they left off. Inhibiting a well-learned automatic sequence is particularly relevant in Parkinson's (freezing). Repeat 8 to 10 times during the session.
Inverted Yes-No
Ask questions to which the natural response would be "yes" — the patient must respond "no" and vice versa. "Is it dark right now? (no) → respond yes." A simple and playful inhibition exercise, easily doable at home or in session. Progress to more complex questions.
Selective reading with inhibition criterion
Read a short text while skipping all words from a defined category (e.g., skip all color words, or all animal names) without saying them aloud. Inhibiting specific words in a continuous reading flow is an advanced form of the inhibition exercise, closer to daily cognitive demands.
FE 4 — Working Memory
Maintain and manipulate short-term information · Exercises 13–16Reverse Digit Span
The caregiver or speech therapist states a series of digits (starting with 3) that the patient repeats in reverse. E.g.: “4 – 7 – 2” → respond “2 – 7 – 4”. Gradually increase the length of the series. This is the working memory exercise most directly correlated with daily life performance in Parkinson's patients.
Multi-step Message
Memorize 3 to 4 actions to be performed in order in different rooms (e.g.: “1. Place a book in the bedroom, 2. Turn off the hallway light, 3. Return by taking the longest route”). Prospective and spatial working memory is one of the most functionally important in daily life for Parkinson's patients.
Series Mental Calculation
Start at 100, subtract 7 each time: 100, 93, 86, 79... Maintaining the current result while calculating the next subtraction is a double demand on working memory. Adjust according to the level (subtract 3 for ease, subtract 7 for standard difficulty, 13 for a challenge).
Delayed Reading Summary
Read a short text (10 lines), set the text aside, wait 5 minutes (during which another activity is performed), then summarize the text from memory — main ideas, retained details, opinion. The voluntary interference between encoding and recall simulates the distractions of daily life that disrupt working memory in Parkinson's patients.
FE 5 — Divided attention and secure dual task
Share attention between two tasks · Exercises 17–20 · Safety first⚠️ These exercises should never be performed while walking on uneven ground or in a fall-risk situation. Always seated or standing stable, on flat and clear ground for motor variants.
Seated dual task: counting + sorting
Seated, sort colored cards with one hand while the other taps a steady rhythm on the table. Then switch hands. Next, sort the cards while counting aloud backwards from 20. This seated dual task is secure and directly targets central attentional sharing.
Rhythmic walking with counting (flat ground, accompanied)
On flat, clear ground, accompanied by a relative or a physiotherapist: walk while counting aloud by 2s. Start with 30-second periods, gradually increasing. The goal is not speed but the simultaneous maintenance of walking AND counting. Stop as soon as the gait deteriorates.
Conversation during a simple manual task
Perform a simple and automated manual task (folding laundry, sorting coins) while maintaining a normal conversation with a relative. Deliberately shift the main attention from the task to the conversation and vice versa. Exercise close to the most demanding daily situations in terms of divided attention.
Reading aloud + sensory monitoring
Read a text aloud while being simultaneously attentive to the sounds of the environment — signal each time a particular sound (bird, car, clock) is heard. Exercise of auditory-visual divided attention that involves no motor risk and can be practiced independently.
3. Adapt the program to Parkinson's fluctuations
3.1 Understand and use on/off windows
The vast majority of Parkinson's patients treated with levodopa experience fluctuations in treatment effectiveness throughout the day. "On" periods — when the treatment is effective — offer better mobility, greater energy, and optimized cognitive abilities. "Off" periods — at the end of treatment effectiveness — are accompanied by motor and cognitive slowing, increased fatigue, and sometimes dysphoria. Adapting the executive function stimulation program to this cycle is essential to maximize its effectiveness and to avoid counterproductive sessions conducted during periods of low cognitive availability.
Not recommended exercises
Dual task, Stroop, Tower of Hanoi, mental calculation in series — these demanding exercises during reduced effectiveness periods generate frustration, errors, and can discourage the continuation of the program.
Light and maintenance exercises
Planning the day, simple mental recipe, gentle thematic conversation, emotional recognition exercises (Facial Expression Decoder). These activities maintain cognitive engagement without overloading.
Ideal window for demanding exercises
30 to 90 minutes after taking the treatment: this is the ideal time for flexibility, inhibition, dual task, and intensive working memory exercises. Plan the most ambitious sessions at these times.
Complete program of 25-30 minutes
5 min heart coherence (activation) → 8 min demanding EF exercise (flexibility or inhibition) → 8 min moderate EF exercise (working memory) → 5 min gentle exercise (planning or emotional recognition) → assessment.
3.2 The role of the Facial Expression Decoder in Parkinson's
A often overlooked deficit in Parkinson's disease is the difficulty in recognizing and interpreting the emotional expressions of others — a disorder related to hypomimia (reduction of the patient's own facial expressions) and changes in amygdaloid and striatal circuits. This social cognition deficit has direct consequences on daily interactions: the patient may miss important emotional signals in a conversation, leading to misunderstandings and gradual social withdrawal.
Daily exercise with the DYNSEO Facial Expression Decoder — identifying and naming emotions on photographed faces — is a direct and targeted training of this ability. It can be integrated into the EF stimulation program as an exercise of social attention and recognition of non-verbal cues, particularly suited for periods of cognitive fatigue as it does not require complex verbal production.
3 bis. Integrate EF into daily activities
Ordinary activities as a continuous stimulation ground
Beyond structured exercise sessions, daily life itself offers permanent opportunities for executive function stimulation — provided they are approached deliberately and consciously. For Parkinson's patients, whose windows of cognitive availability are limited, maximizing the impact of each ordinary activity is as important a strategy as formal exercises.
The meal preparation is one of the richest domestic activities in terms of executive stimulation: planning (defining the order of preparations), flexibility (adapting if an ingredient is missing), working memory (remembering the steps completed and upcoming), inhibition (resisting tasting before finishing), and divided attention (monitoring cooking while preparing something else). Encouraging the patient to prepare their own meal for as long as possible — with safety adaptations if necessary — is an invaluable daily executive exercise.
The medication management is another central executive activity for Parkinson's patients: noting their doses, planning times according to meals, anticipating restocking, adapting if a pill has been forgotten. Using a weekly pill organizer, a displayed tracking chart, or a reminder app is not a capitulation to the disease — it is an executive compensation strategy that frees cognitive resources for other more stimulating activities.
The DYNSEO Wheel of Choices makes perfect sense here: faced with Parkinsonian apathy that can paralyze initiative (“I don’t know what to do, so I do nothing”), the wheel of choices visually offers options for cognitively stimulating activities — gardening, reading, calling a friend, preparing a recipe. Each small act of decision and initiation exercises the prefrontal circuits against apathy, gradually preserving decision-making autonomy.

❓ FAQ — Executive functions and Parkinson's disease
1. What is the difference between memory deficits in Parkinson's and those in Alzheimer's?
The difference is fundamental and clinically important. In Alzheimer's disease, it is recent episodic memory that is affected first — the person forgets recent events irreversibly. In Parkinson's disease, it is first working memory and executive functions that are affected — the person has difficulty organizing and planning, but can often remember recent facts if provided with retrieval cues. The neuropsychological profile is distinct enough to require different assessments and stimulation programs, even though both can coexist in advanced stages.
2. Are these exercises compatible with levodopa treatment?
Yes — and they are more effective in combination with optimized treatment. Dopaminergic treatment improves executive functions by partially restoring fronto-striatal circuits. Complementary cognitive stimulation acts on other mechanisms — neuroplasticity, strengthening of alternative circuits, improvement of cognitive reserve — which add to the effects of the treatment. The important thing is to synchronize the most demanding cognitive sessions with the on periods of treatment, and to communicate regularly with the neurologist about observed progress and difficulties.
3. Are dual-task exercises dangerous for Parkinson's patients?
Improperly supervised, yes. Properly supervised, no — and they are even particularly beneficial as they directly address the dual-task deficit that characterizes Parkinson's. The fundamental precautions: never perform motor-cognitive dual tasks standing or walking without physical support from a relative or physiotherapist, always on flat and clear ground, during on periods, with the possibility of immediate stopping. Pure cognitive dual tasks (counting + sorting cards while seated) are safe and very effective without these risks.
4. How can I tell if my executive functions are deteriorating despite the exercises?
Several practical indicators: daily activities that were easy become difficult (preparing a complex meal, managing one's schedule), errors increase during usual exercises, or cognitive fatigue occurs earlier in the session. For an objective assessment, the DYNSEO executive functions test provides a non-medical indication. A complete neuropsychological assessment, conducted by a neuropsychologist every 12 to 18 months, is the clinical reference for tracking progress and adjusting the program.
5. Can stimulating executive functions delay Lewy body dementia?
No study currently proves that cognitive stimulation prevents or delays Lewy body dementia specifically. What it does — and this is clinically significant — is maintain a higher level of cognitive functioning for longer, by increasing cognitive reserve that compensates for progressive damage. Patients who maintain regular cognitive stimulation generally show better quality of life and preserved autonomy for longer, even though neuropathological progression is not stopped.
6. Can these exercises be conducted by a non-professional relative?
The vast majority of these exercises can be conducted by a trained relative — with the natural limits of non-professional competence. Motor dual-task exercises ideally require supervision from a physiotherapist. Other exercises (planning, flexibility, cognitive inhibition, working memory) are accessible to a motivated and informed relative. DYNSEO training for relatives provides a practical framework for conducting these exercises at home in a structured and safe manner. Regular validation by the neuropsychologist or speech therapist allows for level adjustment and detection of regressions.
7. Is SCARLETT really usable by a Parkinson's patient with tremors?
SCARLETT was designed to be accessible to individuals with motor difficulties — the interface features large buttons, adjustable touch sensitivity, and vocal feedback for important elements. For patients with significant tremors, a suitable grip stylus (available at specialized pharmacies) can facilitate navigation. For severe fluctuations, it is recommended to use SCARLETT during on periods of treatment. An initial presentation by an occupational therapist is often helpful to optimize the personalized configuration of the interface.
8. Does DYNSEO training for relatives cover the cognitive specifics of Parkinson's?
The training "Behavioral changes related to the disease — Practical guide for relatives" covers behavioral and cognitive changes related to chronic neurological diseases, including Parkinson's disease. It provides guidelines on executive deficits and their daily manifestations, communication strategies adapted to on/off fluctuations, and practical tools to support cognitive activities at home.
