Neurofeedback for Strokesadmin2021-04-02T20:02:24+00:00
What is stroke?
A stroke occurs when blood flow to an area of the brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory, mood, speech, balance, ability to walk and muscle control can be lost.
How a person is affected by their stroke depends on where the stroke occurs in the brain and how much the brain is damaged. For example, someone who had a small stroke may only have minor problems such as temporary weakness of an arm or leg. People who have larger strokes may be permanently paralyzed on one side of their body or lose their ability to speak. Some people recover completely from strokes, but more than 2/3 of survivors will have some type of disability. Stroke is the leading cause of adult disability in the U.S.
How can Neurofeedback help with Stroke?
Neurofeedback is a treatment modality that can help the brain repair itself, even years after damage has been done.
Some common repercussions of stroke that can be helped by neurofeedback are:
What is Neurofeedback Training?
Neurofeedback Training is a simple, painless, drugless and non-invasive therapy. It trains the EEG or brainwaves using operant conditioning. Operant conditioning uses auditory and visual feedback to reward the brainwaves when they change in the desired direction to improve problems of speech, movement and mood. An individual learns to control his own brainwaves through the help of visual and auditory feedback.
Neurofeedback training is simple, painless, drugless, non-invasive and virtually has no harmful side effects.
How does Neurofeedback work?
Neurofeedback is a way to quantify and train brain activity.
The basic principles of how neurofeedback works are deceptively simple.
Communication between groups of cells in the brain generates thoughts, sensations, actions and emotions. This activity is detectable in the form of brainwaves – electrical impulses generated by your brain activity.
During a neurofeedback session, sensors detect your brainwaves to see your brain in action. A computer compares your brain activity to targets or goals for you to reach. Through operant conditioning, sounds and images tell you immediately when your brain reaches your goal and when not – when you are activating or suppressing the target area of the brain.
Through this simple method, you learn how to quiet brainwaves associated with low performance and increase brainwaves associated with optimal brain function. Much like physical exercises strengthen and develop specific muscles, the more your brain is exercised into reaching a new more comfortable, more efficient position, the better and stronger it gets.
How do we decide what needs to change?
A thorough assessment is done to determine what the difficulties a person is experiencing along with the history of the problem, family history, and an assessment of brain functioning. A quantitative EEG (QEEG) is performed to collect data under different conditions, eyes closed, eyes open, reading and doing a performance task. We look at the results of the way the brainwaves are working, and we run the results against a normed data base that is the same as the person’s age, gender and handedness. We determine a direction for treatment based on the symptoms of the individual and the quantitative electroencephalogram (QEEG).
How long does it take?
The length of neurofeedback training sessions always depends on the condition, age and health of the patient as well as any other health conditions that are present and need supportive treatment. We find that an average number of sessions to get a significant change to occur are around 20-30 sessions. However, rarely does a case resolve completely in that few sessions. It usually takes around 40 to get the best results. Individuals that have other health concerns need to recognize that Neurofeedback alone cannot do everything and there needs to be a comprehensive understanding and treatment of the overall health problems.
