Neurofeedback: Treatment For Brain Injury

Can Neurofeedback help with Brain Injury ?

In the same way that Neurofeedback can help with brain development issues that are present at birth, it can also help with what are called Acquired Brain Injuries (ABI), or deterioration in brain function over time, known as Neurodegeneration. These include Traumatic Brain Injuries (caused by a physical impact to the head), Non- traumatic Brain Injuries (e.g. strokes, ruptured brain aneurysm, chemical brain injury), and Alzheimer’s and Parkinson’s diseases. father with dementia

Neurofeedback for Traumatic Brain Injury

‘Traumatic Brain Injury’ refers to brain injury caused by external force.  TBIs are often categorised as mild, moderate or severe; however these categories refer to how long consciousness was lost at the time of the injury, and don’t necessarily relate to the severity of the symptoms experienced afterwards. The external force either directly damages the brain by penetrating the skull, or rapid acceleration/deceleration and impact with the skull causes lesions (bruising) to the brain’s surface as it hits the uneven inner surface of the skull), or nerve cell fibres to be stretched, strained or torn; this damage may be microscopic but can still severely disrupt the regulation of the brain, and therefore impact brain function or behaviour. Even so-called mild TBI can result in debilitating ‘post concussion syndrome’ symptoms including depression, ADHD-like symptoms, headaches, anxiety, fatigue, irritability, temper outbursts and aggression, memory problems, sleep disorders and sexual dysfunction, depending on which part of the brain was damaged. Neurofeedback cannot repair physical damage to the brain’s physical structure, but it can use neuroplasticity to exercise and develop new neural pathways and restore brain function. In the early stages after a traumatic brain injury, neurofeedback can be helpful with the head pain that is often experienced, as well as with nausea, irritability, mental confusion, and sleep difficulties. Over the longer term, neurofeedback can be helpful with energy level, vigilance, effort fatigue, cognitive dysfunction traceable to the injury, sensory hypersensitivity, and executive function. Eventually memory function should recover as well. Many of these symptoms are known to recover spontaneously, so how do we know that neurofeedback has helped and the recovery it not just part of the natural process ? It is known that the spontaneous recovery process plateaus out within about 18 months post- trauma. In actual clinical experience, most head-injured clients don’t find their way to a neurofeedback practice until years have passed since the trauma, so the symptoms are quite stable and the natural recovery process has run its course.

Margaret Ayers was one of the early neurofeedback practitioners to treat traumatic brain injury, treating hundreds of patients and achieving remarkable results particularly with recovery from coma in the 1980s. Dr. Jonathan Walker, a Dallas neurologist, observed significant improvement in 88% of a group of 26 patients with mild closed-head traumatic brain injury. Every one of them who had held a job prior to their injury was able to resume productive employment after neurofeedback. The average number of neurofeedback sessions was 19. These results were obtained with techniques that are now nearly ten years old and significant improvements in training methods have been made within the last decade. The result is that head injury symptoms showing themselves to be resistant to remediation may be targeted more specifically.

Neurofeedback for Nontraumatic Brain Injury

There are three aspects of stroke that NF can help with:

  1. The specific loss of function associated with the damage – e.g. language (aphasia), movement, vision;
  2. The more diffuse symptoms that may have emerged after the stroke or any associated surgical procedure, including irritability, pain, sleep problems, mood swings, effort fatigue, or cognitive fog;
  3. The psychological impact of any major loss of function and the acceptance of this – the potential loss of career, relationship issues, reduced social circle.

The normal order in which to tackle these is first the diffuse symptoms, then psychological impacts, and then the specific loss of function. Regaining lost function is understood as a two stage process:

  1. The first stage involves the functional reintegration of neuronal resources that remained structurally sound after the stroke but are no longer functionally integrated. This process is similar to what takes place in other recovery conditions such as Parkinson’s, dementia, and chemical injury (e.g. CO poisoning). Progress is expected to be seen in a modest number of sessions, and progress may start to plateau in the range of twenty to forty sessions.
  2. Over the longer term, dendritic regrowth may present a further opportunity for functional recovery. One can sample this process by training at some interval, like once a month, and that process may continue for years. Also, the gradual reassignment of function that can occur in the brain may also be reinforced by neurofeedback.

In developing a training plan for stroke recovery, we would want to understand how the client was before the stroke, for example if they were a hard-driving individual with high blood pressure we would focus on the right-side for physical and emotional calming. If the a left brain stroke had caused loss of language and right side physical strength we would train both left and right sides.

What is the evidence for Neurofeedback’s efficacy for Brain Injury ?

Margaret Ayers was one of the early pioneers to apply Neurofeedback to brain injury and become well know for assisting coma victims to recover. One of her case study collections published in Head Injury Frontiers, describes 250 cases of closed head brain injury she treated. Some of the peer-reviewed studies that have been published on Neurofeedback’s ability to help brain injury are listed below:

Publication Date Reference Summary of Research Summary of Findings
Head Injury Frontiers 1987 Ayers, M. E. “Electroencephalic neurofeedback and closed head injury of 250 individuals.” Head injury frontiers (1987): 380-392. Large case study of 250 patients with head injury treated with 24 sessions of Neurofeedback. Most patients returned to pre-injury function.
Journal of Head Trauma Rehabilitation
2000
Case studies to assess how EEG biofeedback could improve memory deficit problems as a result of brain injury.
Improvements ranged from 68% to 181% in the group of patients with brain injury, as a result of the EEG biofeedback interventions.
Journal of Neurotherapy
2002
26 patients with mild closed head injury had neurofeedback, training continued until the patient indicated that significant improvement had occurred or 40 sessions were reached.
Significant improvement (>50%) was noted in 88% of the patients (mean = 72.7%). All patients that were employed before the injury returned to work. On average, 19 sessions were required.
