Neurofeedback, a form of biofeedback, provides a visual and/or audio representation of an individual's neural electrical activity from live EEG recording. Using operant conditioning principles, individuals are trained to increase or reduce patterns of brainwave activity to modify behavior and performance. Although neurofeedback has not yet been investigated as a treatment for aphasia or other communication deficits due to stroke or neurodegenerative disease, it may be effective. Previous studies have observed improvement in cognitive and behavioral measures in those with conditions such as Attention Deficit Disorder and Attention Deficit Hyperactivity Disorder. Furthermore, it has been associated with reduced anxiety and sleep disruption, which both exacerbate language and communication impairments. Research is needed to determine if neurofeedback may be an effective treatment for language disorders such as PPA and post-stroke communication disorders.
It is possible that EEG neurofeedback, which focuses on improving abnormal brainwave patterns, could provide certain therapeutic benefits to individuals with PPA or post-stroke aphasia, either by directly affecting neural networks that underlie language, or more generally by reducing anxiety and inattention through behavioral conditioning. Reduction of anxiety in neurological diseases can be beneficial not only for functional performance but also sleep duration and quality.
