Testing and Therapy
Botulinum Toxin Therapy (Botox) for Migraine and Other Conditions
Our neurologists are experienced in the use of botulinum toxin therapy for migraine, hyperhidrosis therapy, contractures, and temporomandibular (TMJ) joint disorders.
This involves careful injection around multiple areas of the head and neck, and is able to be performed easily and efficiently.
The term 'Hyperhidrosis' refers to chronic sweating in amounts greater than what the body needs and, understandably, this can have a severe impact on a person’s self-confidence and their professional and social relationships. Patients usually have excessive sweating of the palms, underarms (axillae) or soles of the feet.
Treatment for hyperhidrosis can involve botulinum toxin injection therapy to the affected area, thought it is often recommended as a second line therapy. It reduces sweating temporarily by blocking the neuronal release of the neurotransmitter acetylcholine. A response to treatment with botulinum toxin is usually seen within 2-4 days and an improvement in sweating can last 3-9 months or longer, with significant individual variation.
Nerve Conduction Studies
A neurologist may order testing called nerve conduction studies in order to better understand how the nerve pathways are working from the spinal cord right through to the muscle. Sometimes this is combined with direct testing of the muscle using a small needle to measure activity. The test usually takes between 30 and 60 minutes though this can vary.
These tests are often an important part of investigation into a neurological symptom or symptoms. They can be used to monitor a response to treatment.
The test involves use of small electrical impulses that can be uncomfortable but this is usually transient, with opportunity to rest or take a break, and many patients find the test very tolerable.
Electromyography (EMG) or Muscle Testing
This is the specific evaluation of changes in the muscle relating to nerve disease or direct muscle disease.
It involves insertion of a small needle that cam measure the response of a muscle to activity and when resting. This test is often used in conjunction with nerve conduction studies. It is important to inform your technician or neurologist of any blood thinning medication or bleeding disorder prior to testing. The test usually takes 30-60 minutes but this can vary.
Electroencephalogram (EEG) Brain Wave Testing
An EEG is a test measuring the electrical activity of the brain. It is a safe, monitored test using leads that are temporarily attached or glued to the scalp (please bring a comb) and analysis is performed using a computer screen to record the electrical rhythmical changes or waveforms.
It is often performed for changes of seizure, however it may be used to detect abnormalities that relate to trouble with thinking and memory, or brain infection (encephalitis).
Sometimes patients are asked to become sleep deprived leading up to their EEG to make changes of seizure more easily detected.
