How BioFlex laser therapy is effective in treating various neurological conditions?

Neurological disorders are diseases of the central and peripheral nervous system. In other words, the brain, spinal cord, cranial nerves, peripheral nerves, nerve roots, autonomic nervous system, neuromuscular junction, and muscles. These disorders include epilepsy, Alzheimer’s disease and other dementias, cerebrovascular diseases including stroke, migraine and other headache disorders, multiple sclerosis, Parkinson’s disease, neuro-infections, brain tumours, traumatic disorders of the nervous system due to head trauma, and neurological disorders as a result of malnutrition.


A concussion is a mild traumatic brain injury (TBI). It can occur after an impact to your head or after a whiplash-type injury that causes your head and brain to shake quickly back and forth. A concussion results in an altered mental state that may include becoming unconscious. The most common symptoms are headache, irritation, dizziness and memory loss. It can be mild as well as severe. If it is mild, it could heal up immediately otherwise in chronic or severe conditions it might take a lot of time to heal ranging from days to years. Like many diseases concussions also has its after-effects like headache, dizziness, insomnia, fatigue, cognitive impairment, and behavioural changes. Around 80% suffering from concussions have these effects known as post-concussive syndrome.

Nowadays, laser therapy has done wonders with its uses and it is also used in the treatment of concussions. The process of laser therapy is very simple in which photons which are energy particles are released and absorbed by cellular structures activating the process of metabolism in affected tissues and healing all kinds of swellings thus removing symptoms.

Dr Kahn is one of the renowned doctors in the field of laser therapy, he has treated many patients, one of the patients wrote that he had concussions which caused stiffness in his neck, severe fatigue and restlessness and sensitivity towards light and noise. He said that he had lost hope but then he got treatment from Dr Kahn. He had sessions two times a week for about ten weeks. And, after ten weeks, he steadily and slowly recovered, physically as well as emotionally. The flag bearers of the BioFlex low-level laser therapy, Meditech Laser Rehabilitation Center in Toronto, have announced great success in treating post-concussive syndrome with laser therapy.


Headaches are one of the most common medical complaints; most people experience them at some point in their life. They can affect anyone regardless of age, race, and gender.

The World Health Organization (WHO) reports that almost half of all adults worldwide will experience a headache in any given year.

A headache can be a sign of stress or emotional distress, or it can result from a medical disorder, such as migraine or high blood pressureanxiety, or depression. It can lead to other problems. People with chronic migraine headaches, for example, may find it hard to attend work or school regularly.

Low light laser therapy can cure many disorders including temporomandibular joint disorders (TMJ), sinus headaches, tension and cluster headaches, migraines, and cervicogenic headaches. The process by which LLLT treats these disorders involves elevating local micro-inoculation and raising the amount of serotonin in the blood. These hormones naturally occur in the body to operate the excretion of endogenous opioids (natural pain-relieving system) which changes cholinesterase levels (enzyme for normal functioning of the nervous system). Studies have shown that light therapy elevates blood circulation and serotonin in patients suffering from TMJ syndrome. On average, pain decreased from 9.1 to 3.3 (on the scale of 1-10).


A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures). When that happens, part of the brain cannot get the blood (and oxygen) it needs, so it and brain cells die. A stroke is a medical emergency. Prompt treatment is crucial. Early action can minimize brain damage and potential complications. Symptoms include:

  1.  The trouble with speaking and understanding
  2. Paralysis or numbness of the face, arm or leg
  3. The difficulty is seeing with one or both eyes
  4. Headache and migraine
  5. Cannot walk properly

The success of cold laser therapy depends upon increase activation of mitochondrial pathways and an increase in the energy state. The same process of cellular activity in the brain with laser exposure was observed. Studies have shown that this technique is used for improved neurological and functional outcome.

Parkinson’s disease

 Parkinson’s disease is a progressive nervous system disorder that affects movement. It is one of the fast-growing diseases and develops through regression of nerve cells in the substantia nigra part of the brain which controls movement. Due to the degeneration of nerve cells, they cannot produce dopamine which is a crucial chemical. Symptoms of Parkinson’s disorder include:

  • Difficulty in movement trembling in hands
  • Loss of balance and coordination in body parts
  • Fixed facial expressions due to alteration in nerves controlling face muscles
  • Gait issues
  • Trembling voice
  • Loss of senses and restlessness due to sleep deprivation
  • Depression
  • Constipation
  • Mood swings

To treat Parkinson’s disease Cold laser therapy is a targeted therapy and is being used effectively in this regard. This technique basically utilizes oriented therapy used for stabilizing defective neurons. In Cold laser therapy, light illumination is used to heal tissues of the brain which are suffering from oxygen deficiency, degraded environment, and mitochondrial dysfunction. Cold laser therapy protects dopamine-producing neurons by minimizing loss and death and by reducing swelling in the affected areas and by upgrading mitochondrial functions.


Depression (major depressive disorder) is a common and serious medical illness that negatively affects how you feel, the way you think and how you act. Fortunately, it is also treatable. Depression causes feelings of sadness and/or a loss of interest in activities once enjoyed. It can lead to a variety of emotional and physical problems and can decrease a person’s ability to function at work and at home. Symptoms of depression include:

  • Tension
  • Loss of interest
  • Abrupt weight loss
  • Insomnia
  • Restlessness
  • Fatigue
  • Loss of appetite
  • Suicidal thoughts

Low-level laser therapy is used to increase the number of monoamine neurotransmitters in the brain as pathogenesis of depression is mainly dependent upon neurotransmitters. Depression happens mainly due to monoamine neurotransmitters including dopamine, serotonin, and norepinephrine. These hormones regulate emotions mainly through serotonin. Moreover, in depression, ATP synthesis is reduced so mitochondria do not function properly hence, LLLT increases the amount of ATP synthesis, fixing mitochondria.

Alzheimer’s disease

It is a growing disorder which degenerates brain cells causing memory loss. Alzheimer mostly leads to dementia which disturbs a person’s ability to function properly. Symptoms of Alzheimer’s include:

  • Forgetting recent events or conversation and memory impairment
  • Got lost in thoughts
  • Forget names
  • Repeat statements in conversation

Alzheimer’s affects a person’s memory, decision-making ability, planning, personality, and thinking. It is impossible to cure Alzheimer permanently, medications may improve symptoms for time being or slow down the process but it cannot heal the disorder. Alzheimer’s disease may lead to death even in chronic stages. Application of low-level laser therapy (LLLT), with its reasonable emission of photons, has been shown to adjust cellular metabolism and changes the transcription factors responsible for gene expression to produce cell regeneration translating to a beneficial clinical effect. Through the application of LLLT to individuals with AD, improvement in the expression of symptoms of AD had been observed. Low-level Laser therapy trials have shown helpful clinical effects for other neurodegenerative and neurodevelopmental disorders such as Parkinson’s disease and Autism Spectrum Disorder. It is hoped that one day, it might heal up Alzheimer permanently.
