Why take care of our cognitive functions?
Cognitive disorders are affecting more and more people: memory difficulties, loss of attention, mental fog, even dementia linked to diseases such as Alzheimer's.
These manifestations weigh heavily on daily life, autonomy and family life. Faced with the limitations of current medications, photobiomodulation or PBM could represent a gentle, non-invasive approach that naturally supports the neurological sphere.
Understanding neurological and cognitive disorders
These signs can appear after prolonged stress or infection, or as part of inflammatory and neurodegenerative diseases.
Assigned function
Memory, attention, executive functions, mood and motivation
Common symptoms
Recent forgetfulness, misplaced objects, Distractions, inattention errors, attention disorders, Difficulty planning, deciding, Apathy, irritability
Possible impact
Impairment in professional life, Decreased performance at school or at work, Progressive loss of autonomy, Social withdrawal, Mental fatigue
Diseases concerned: a quick overview
Some cognitive disorders that can be improved with PBM:
Alzheimer's and other disorders
Progressive disorganization of memory and reference points.
Post-infection mental fog
Persistent cognitive difficulties after certain viral diseases.
ADHD in children and adults
Attention deficit disorder with impulsivity and hyperactivity.
Age-related decline
Slower cognitive processes and reduced mental alertness.
How light naturally supports your brain
Transcranial photobiomodulation (PBM) involves applying red or near-infrared light directly to the scalp to support brain cells without surgery, injections or pain. The specific wavelengths (usually around 810 nm) pass safely through the skull and reach the cortical layer of the brain, where key areas linked to memory, concentration and emotional regulation reside. Why does it work?
Mitochondrial stimulation
Light increases cellular energy, essential for neuronal function.
Optimizing cerebral circulation
It improves blood perfusion, promoting the supply of oxygen and nutrients to cortex cells.
Regulation of neuroinflammation
It improves blood perfusion, promoting the supply of oxygen and nutrients to cortex cells.
Safety first
Modern protocols guarantee safe exposure, without tissue heating or damage to deep brain structures. Protective eyewear is used to shield the eyes from intense photons during sessions.
Reported clinical benefits
In practice, many users report a positive experience from the very first weeks, with a gradual improvement in mental clarity and quality of life. These results support autonomy, concentration and cerebral comfort in everyday life. Numerous studies and clinical observations show that transcranial photobiomodulation (PBM) can actively support several major cognitive functions. Transcranial photobiomodulation sessions are associated with several significant benefits observed in the user experience:
Improved working memory
Some studies have shown up to +25% increase in performance after 8 weeks, greater autonomy and more fluid memories.
Reduced cognitive stress
Perceived 30% reduction in mental fog in people after convalescence or cognitive overload.
Increased attention and reaction time
Enhanced concentration, increased alertness, fewer attention problems and improved response time on simple cognitive tasks.
Boosting morale and motivation
Many testimonials point to greater emotional stability and an increased desire to resume social or professional activities.
Practical applications and profiles
Photobiomodulation or cerebral PBM can be used in a variety of situations:
1.
Seniors in cognitive maintenance
Sessions can support memory, slow the loss of mental agility, and prolong independent quality of life in the face of natural brain aging.
2.
People living with early-onset neurodegenerative disorders
In the early stages of diseases such as Alzheimer's or Lewy body dementia, photobiomodulation can complement conventional approaches by supporting residual neuronal activity.
3.
Students and workers under cognitive stress
Preparing for exams, mental overload at work: a light photobiomodulation protocol can help restore clarity of mind and improve performance.
4.
Children and adolescents with attention deficit disorder (ADHD)
Under specialized supervision, photobiomodulation (PBM) can support attention span and reduce mental agitation, complementing educational and behavioral strategies.
5.
Focus on personalization
Every inflammatory situation is unique: adapting light care to the user's profile, the underlying problem and the stage of inflammation is essential to maximize effectiveness.
Recommendations for optimizing results
Some numerical recommendations to help you better understand photobiomodulation sessions:
Sessions per week
Ideal frequency over an initial period of 6 to 8 weeks to gradually build up cognitive benefits.
Each session lasts between 12 and 20 minutes, depending on the objective and the frontal or parietal area targeted.
Use devices emitting between 630 and 850 nm, with a delivered energy of 8 to 12 J/cm² to guarantee effective stimulation without overheating.
Moderate physical activity
Maintain moderate physical activity, a good sleep pattern and a balanced diet to maximize the positive impact on cognitive health.
Professional follow-up
Follow-up by a trained professional can enable the protocol to be adapted according to the evolution of cognitive symptoms and individual response.
