Biofeedback and Self-Regulation

|September 1, 1995

Summary

This study shows that a neurotherapy approach improved speech, memory, and mood in a stroke patient. Neurofeedback effectively reduced abnormal brainwave activity, leading to significant functional recovery.

Background:

Stroke, or cerebrovascular accident (CVA), can lead to persistent cognitive and motor deficits.
Left internal carotid artery occlusion can cause left posterior temporal/parietal infarctions, impacting various neurological functions.
Neurotherapy offers potential avenues for stroke recovery and symptom management.

Observation:

A 55-year-old male with a left-side CVA presented with speech difficulties, visual disturbances, balance issues, memory and concentration deficits, anxiety, depression, and tinnitus.
Quantitative electroencephalograph (QEEG) revealed increased left-side 4-7 Hz activity and alpha persistence.
The patient underwent a six-month, two-tiered neurotherapy program involving electroencephalographic entrainment feedback (EEF) and targeted neurofeedback.

Findings:

Neurotherapy successfully reduced abnormal slow-wave activity (4-7 Hz) and increased faster brainwave activity (15-21 Hz) over sensorimotor and speech areas.
Significant improvements were observed in speech fluency, word finding, balance, coordination, attention, and concentration.
The patient experienced substantial reductions in anxiety, depression, and tinnitus.

Implications:

This case study suggests neurotherapy is a promising intervention for post-stroke neurorehabilitation.
Targeted neurofeedback may effectively address specific EEG abnormalities linked to stroke-related symptoms.
Further research is warranted to validate these findings in larger stroke patient cohorts.
