Tremor: What It Is, Causes & Treatment

The history and temporal development can provide clues, as these tremors develop within a shorter time.74 Treatment of the underlying disorder is paramount. Symptomatic treatments of the tremor include similar options as for other types of tremor. A number of medications can cause parkinsonism because they block the dopamine receptor and thereby mimic the symptoms of PD that are caused by loss of dopamine neurons in the brain. Reviewing a patient’s medications is therefore a critical step for a neurologist when seeing someone with parkinsonism. Anti-psychotics and anti-nausea treatments make up the bulk of the problematic medications, although there are other medications that can also cause parkinsonism. The primary treatment for this type of parkinsonism is weaning off of the offending medication, if possible.

Clinician Reviewer

• It occurs due to the relationship between dopaminergic loss and the resultant response to levodopa, rather than being due to excess levodopa ingestion only.
• Exposure to toxic levels of certain drugs (e.g., ethanol, lithium, etc.) for longer periods of time can lead to permanent tremors, especially if they affect the cerebellum.
• Tremors aren’t life-threatening, but they may be embarrassing for you if they happen in public.
• The most often encountered tremors have frequencies between 4 and 12 Hz.1 Tremor in PD usually has a slower frequency of between 3 and 5 Hz, and essential tremor and enhanced physiologic tremor range from 5 to 10 Hz.
• If you have diabetes, tremor can be a symptom of low blood sugar levels.
• There clearly is a need for more effective treatments for most forms of tremor, and the underlying neurologic disorders that cause tremor.
• Levodopa-induced dyskinesia is a common cause of dyskinesia in individuals with Parkinson’s disease.

However, for some patients, even mild physiologic tremor can lead to large degrees of embarrassment and functional disability, such as the violinist at a decisive audition, or any professional giving an important presentation. The use of a β-blocker (e.g., propranolol) before such a situation may alleviate the tremor, but the optimal dose should be found prior to the important event. Tremors can occur in the setting of withdrawal states, especially with benzodiazepines, ethanol, and opiates.

Bring all your concerns to the attention of your physicians and remember to always consult with your physician before you make any changes to your medication regimen. Tremor is significant as a medical symptom when it affects your daily activities, like your ability to eat food, walk, dress or work. Some conditions — like essential tremor — only have tremor as a symptom. In other conditions (like Parkinson’s disease and multiple sclerosis), tremor can be one of many symptoms (or features) of them. Finally, it will be important to further define the most vital anatomical structures for the generation of tremor in the CNS and further understand the physiology of these interconnected players. It will also be important to develop further knowledge of neurotransmitters and their receptors that may influence tremor or actually suppress it.

Selective serotonin reuptake inhibitors

As the injectable drug has a short half-life it is followed by a short course of oral anticholinergic drugs.4,5,7 Benzodiazepines have also been used. It is what medications cause tremors important to avoid the offending drug in the future due to the risk of a recurrent dystonic reaction. To decrease fall risk, medicines such as opioids and antidepressants may need to be slowly decreased and eventually stopped. However, stopping medicines could create a greater risk of health issues. For some people, the benefits of taking certain medicines outweigh the risks.

Living with Parkinson’s Disease

• Intention tremor is a subheading of kinetic tremor that is a terminal kinetic tremor (as can be seen when nearing the target on finger-to-nose testing).
• The most important parameter for tremor evaluation is describing when the tremor occurs in relation to movements or position of the affected body part, distinguishing between tremor at rest (rest or resting tremor) and action tremor.
• This can help you and your doctor figure out which specific medication, or combination of medicines, is causing your symptoms.
• On the other hand, computational modeling and circular dichroism indicated that the p.L259P mutation affects the structure of the M-motif by reducing its helicity, potentially rendering the mutant protein relatively unstable (Shashi et al. 2019).
• If you develop tremor — or an existing tremor gets worse — after starting a medication, tell your healthcare provider.
• Typical parkinsonian or cerebellar gait may be noted, and muscular rigidity in combination with a tremor at rest is typical for PD, whereas spasticity may develop in multiple sclerosis.
• ZKW is partially supported by the NS40256, NS057567, AG017216, NS070276, Mayo Clinic Florida Research Committee CR program, and a gift from Carl Edward Bolch, Jr. and Susan Bass Bolch.

The most important parameter for tremor evaluation is describing when the tremor occurs in relation to movements or position of the affected body part, distinguishing between tremor at rest (rest or resting tremor) and action tremor. This distinction helps in grouping tremors according to their pathophysiology and etiology, which in turn is highly relevant for choosing the most promising treatment option. Newborn babies with ANM develop tremor within a few days after birth, followed by progressive muscle weakness, rigidity and contractures (Johnston et al. 2000). Muscle biopsies from four ANM patients obtained within the first year of their life displayed prominent type 1 fiber disproportion in quadriceps muscle, Z-band streaming, central refractile rods, myofibrillar disruption, and myofiber degeneration (Johnston et al. 2000). In six patients of the multi-generation Swedish carrier family (Martinsson et al. 2000), type 2A fibers were small and infrequent, while other fiber types appeared normal. Moreover, rimmed vacuoles were frequent with inclusions of 15–20 nm tubulofilaments (Martinsson et al. 2000).

But there are actions you can take to manage the underlying condition and take back some control. The treatment for tremor depends largely on the type and the underlying cause. But tremor that happens due to medications, substances or metabolic conditions typically is. Stop the offending drug, and give an intravenous or intramuscular anticholinergic drug (such as benzatropine or trihexyphenidyl (benzhexol) hydrochloride).

Medicines that increase fall risk in older adults

The clinical and electrophysiological features of valproic acid-induced tremor appear typical of EPT given treated patients had a reduction in their tremor frequency by 3 Hz or more by weight loading.15,45 This is typical of an alteration in the frequency of the mechanical component of physiological tremor. Taken together, we propose to establish this form of myopathy accompanied by tremor, of likely myogenic origin, as a new disease entity with the ultimate goal to improve diagnosis and develop more appropriate and effective therapies. It is our hope that in the immediate future, an emphasis will be given by the muscle scientific community in dissecting the complexity and intricacies of this new form of sarcomeric myopathy with tremor. Furthermore, tremor may diminish in later stages of the disease, when bradykinesia becomes more prominent.46 The typical and rather complex movements of parkinsonian rest tremor (Fig. 2) indicate PD with high specificity. They include agonist and antagonist activation alternating in a precisely tuned manner, often leading to a stereotypical series of movements, such as the typical pill-rolling tremor. Sometimes, a person without a diagnosis of PD is prescribed a medication which leads to a side effect of drug-induced parkinsonism.
