From the Guidelines
Botulinum neurotoxin injections, specifically OnaBoNT-A and incoBoNT-A, are the most effective treatment options for involuntary nodding movement of the head, also known as essential head tremor (EHT) or cervical dystonia. When considering treatment for EHT, it is crucial to prioritize the patient's morbidity, mortality, and quality of life. According to the American Academy of Neurology's updated guidelines on the uses of botulinum neurotoxin 1, OnaBoNT-A and incoBoNT-A are equally effective and should be considered for treatment of blepharospasm and cervical dystonia. Some key points to consider when treating EHT include:
- The use of botulinum neurotoxin injections to treat cervical dystonia, despite differing evidence levels 1
- The effectiveness of OnaBoNT-A and incoBoNT-A in treating cervical dystonia, with similar efficacy to AboBoNT-A and rimaBoNT-B 1
- The importance of consulting a neurologist for proper diagnosis, as the nodding could result from various conditions including essential tremor, cervical dystonia, Parkinson's disease, or medication side effects, each requiring different treatment approaches. It is essential to note that the treatment approach may vary depending on the underlying cause of the involuntary nodding movement, and a thorough evaluation by a neurologist is necessary to determine the best course of treatment.
From the Research
Treatment Options for Involuntary Nodding Movement of the Head
- The treatment for involuntary nodding movement of the head, also known as essential head tremor (EHT), includes botulinum toxin injections, which have been shown to be effective in treating various movement disorders, including dystonias and tremors 2, 3.
- Botulinum toxin injections can be used to treat focal dystonias, such as blepharospasm, and can provide significant improvement in symptoms 4.
- The use of botulinum toxin injections has been found to be safe and effective in treating patients with dystonic tics, including those with Tourette's syndrome 4.
- Other treatment options for abnormal involuntary movements, including EHT, may include pharmacotherapy, physical therapy, and surgical interventions, depending on the underlying cause and severity of the condition 3, 5.
- A comprehensive treatment approach that takes into account the physical, psychological, and social aspects of the condition is essential for providing patient-centered care and promoting overall well-being 6.
Botulinum Toxin Injections
- Botulinum toxin injections work by inhibiting the release of acetylcholine at the neuromuscular junction, causing weakness in the affected muscles 2.
- The use of electromyography and ultrasound can improve the accuracy of botulinum toxin injections and reduce the risk of side effects 2.
- Botulinum toxin injections are generally well-tolerated, with few side effects, and can provide significant improvement in symptoms for several months 2, 4.
Assessment and Diagnosis
- Accurate assessment and diagnosis of abnormal involuntary movements, including EHT, are crucial for developing an effective treatment plan 6.
- The use of well-validated measurement scales, such as the Abnormal Involuntary Movement Scale (AIMS), can help clinicians quantify the severity and progression of symptoms and track treatment response over time 6.
