1. What is speech therapy and its role in cognitive disorders?
Speech therapy, a recognized paramedical discipline since 1964 in France, derives its name from the combination of the Greek terms "ortho" (right, correct) and "phonie" (voice, sound). This therapeutic specialty is dedicated to the prevention, assessment, and treatment of human communication disorders in all its forms: oral language, written language, voice, speech, and oro-facial functions.
In the context of neurodegenerative diseases like Alzheimer's, the speech therapist becomes a central figure in the multidisciplinary team. Their intervention is not limited to simple rehabilitation: it encompasses a holistic approach aimed at maintaining, stimulating, and adapting communication abilities in response to the progression of the disease. This early intervention proves crucial for preserving autonomy and quality of life for patients.
The modern speech therapist has a varied therapeutic arsenal, including revolutionary digital tools like COCO THINKS and COCO MOVES. These applications, specifically developed for cognitive stimulation, allow for personalized and evolving training, tailored to the preserved abilities of each patient.
💡 DYNSEO Expert Advice

Key points of modern speech therapy:
- Comprehensive assessment of communication abilities
- Development of personalized compensatory strategies
- Use of innovative digital tools
- Support for the family environment
- Coordination with the multidisciplinary medical team
2. The mechanisms of action of speech therapy on the brain
The effectiveness of speech therapy in cognitive disorders relies on the principles of brain neuroplasticity. This ability of the brain to reorganize and create new neural connections remains active even in the presence of neurodegenerative pathologies. The speech therapist exploits this plasticity to develop alternative communication circuits and maintain preserved functions.
Speech therapy exercises simultaneously stimulate several brain areas: the language zones (Broca's and Wernicke's areas), the memory regions (hippocampus, temporal cortex), and the executive circuits (prefrontal cortex). This multisensory stimulation promotes the creation of new neural networks, partially compensating for deficits caused by degeneration.
The structured repetition of cognitive exercises, such as those offered by our applications COCO THINKS and COCO MOVES, reinforces these compensation mechanisms. Regular training helps maintain functional abilities longer and slows the progression of disorders.
Our research shows that the daily use of structured cognitive exercises can increase the duration of maintenance of communication abilities by 40% in patients at mild to moderate stages of Alzheimer's disease.
• Strengthening of existing synaptic connections
• Activation of alternative neural circuits
• Stimulation of neurotransmitter production
• Improvement of cerebral perfusion
To optimize the effects of neuroplasticity, alternate cognitive stimulation exercises with adapted physical activities. This combination maximizes the production of neurotrophic factors promoting the creation of new connections.
3. Speech therapy assessment and diagnosis in Alzheimer's disease
The speech therapy assessment is the cornerstone of effective management. It begins with an in-depth interview with the patient and their family, exploring the communication history, language habits, and the evolution of observed difficulties. This anamnesis allows for understanding the pre-morbid profile and identifying preserved resources.
The speech therapist then uses a battery of standardized tests adapted to cognitive disorders: assessment of oral and written language, tests of semantic and episodic memory, analysis of pragmatic and communicative abilities. These tools allow for quantifying deficits and tracking their evolution over time.
Modern assessment also integrates digital evaluations through platforms like our DYNSEO solutions. These tools offer increased precision in measuring performance and allow for objective longitudinal monitoring of the evolution of cognitive abilities.
🎯 DYNSEO evaluation protocol
Our evaluation protocol includes 3 distinct phases: initial assessment (2 sessions), implementation of the personalized program, and quarterly re-evaluations to adapt therapeutic objectives.
Areas assessed during the evaluation:
- Oral and written comprehension (words, sentences, texts)
- Oral expression (naming, fluency, pragmatics)
- Reading and writing abilities
- Working memory and semantic memory
- Executive functions and attention
- Swallowing and oro-facial functions
4. Oral language disorders specific to Alzheimer's disease
Oral language disorders in Alzheimer's disease present a characteristic evolution in three phases. In the mild stage, lexical retrieval difficulties (word finding), semantic paraphasias, and a reduction in verbal fluency are primarily observed. The patient generally retains good comprehension and can maintain social conversations.
In the moderate stage, the disorders worsen with the emergence of comprehension difficulties, syntactic simplification, and pragmatic disorders affecting the adaptation of speech to context. Communication becomes less effective, requiring adapted compensatory strategies.
In the severe stage, there is a drastic reduction in vocabulary, echolalia, and sometimes progressive mutism. Speech therapy intervention then focuses on maintaining basic forms of communication and supporting the surrounding individuals.
Our longitudinal studies on 500 patients show that early speech therapy intervention can delay the onset of significant comprehension disorders by an average of 18 months.
• Difficulty finding the right word (anomia)
• Use of generic words ("thing", "stuff")
• Repetitions and circumlocutions
• Difficulty following a conversation with multiple people
To facilitate exchanges, use short sentences, allow for response time, and don't hesitate to rephrase differently if necessary. The applications COCO THINKS and COCO MOVES offer specific exercises to maintain these skills.
5. Management of written language disorders
Written disorders in Alzheimer's disease progressively affect reading and writing abilities, following a gradient of complexity. Reading familiar words is generally preserved longer than reading new words or pseudo-words. The speech therapist exploits this relative preservation to maintain access to written language for as long as possible.
Writing deteriorates along several dimensions: spelling difficulties, syntactic simplification, spatial organization disorders, and degradation of handwriting. Speech therapy intervention aims to compensate for these deficits with adapted strategies and the use of technical aids.
Digital tools are revolutionizing this management. Our applications offer graded exercises in reading and writing, with immediate feedback and automatic adaptation to the patient's level. This playful approach maintains motivation while effectively working on targeted skills.
📝 Strategies for maintaining writing
Prioritize handwriting at the beginning, then gradually introduce digital tools. Writing familiar words (first name, address) should be practiced daily to maintain these automatisms.
Recommended exercises for writing:
- Copying short and familiar texts
- Dictation of everyday words
- Completion of fill-in-the-blank sentences
- Reading aloud with visual support
- Adapted crossword puzzles
- Use of specialized applications
6. Management of swallowing and oro-facial disorders
Swallowing disorders (dysphagia) affect 45% of patients with Alzheimer's disease, particularly in moderate to severe stages. These difficulties result from damage to the brain areas controlling the coordination of the phases of swallowing: oral preparatory, oral, pharyngeal, and esophageal.
The speech therapist precisely assesses these disorders through clinical observation and sometimes additional examinations (videofluoroscopy). The intervention includes muscle strengthening exercises, oro-facial stimulation techniques, and adaptation of food textures according to preserved abilities.
Preventing aspiration is a major issue. The speech therapist trains the caregivers in safe postures, appropriate textures, and warning signs that require urgent medical intervention. This family education proves crucial for maintaining home care.
Untreated swallowing disorders can lead to serious complications: aspiration pneumonia, malnutrition, dehydration. Regular speech therapy follow-up reduces these risks by 60%.
• Coughing during or after meals
• "Wet" voice after swallowing
• Food residue in the mouth
• Sudden food refusal
• Repeated respiratory infections
Split meals, avoid mixed textures (soup with chunks), favor a calm atmosphere, and allow the necessary time. Hydration may require thickeners under medical advice.

The speech therapist teaches families facilitating communication techniques: rephrasing, closed questions, use of visual aids, managing communication-related behavioral issues. These skills significantly improve the quality of daily interactions.
The psychological support for caregivers is crucial. The gradual deterioration of communication abilities generates stress, frustration, and exhaustion. The speech therapist offers adaptation strategies and refers to specialized support resources when necessary.
Families trained in speech therapy techniques allow for a 70% improvement in daily communication effectiveness compared to exclusively professional care.
