Cell loss in the locus ceruleus leads to decreased noradrenergic stimulation of Purkinje celis, which reduces their inhibitory effect on the dentate nucleus and the other components of the triangle of Guillain and Mollaret. A wide array of treatment modalities are available for tremor, and most depend on the type or the underlying cause of the tremor. The overall effectiveness of pharmacologic treatments of tremor unfortunately remains mediocre, and patients frequently decide to discontinue such treatments. A fraction of patients with tremor has such severe symptoms that surgical procedures, such as deep brain stimulation (DBS), may be necessary.

Given the etiology of the tremor to be central, a causal therapeutic approach with botulinum toxin seems not feasible. The impact of medication-induced hand tremors extends beyond the physical symptoms, influencing all aspects of a patient’s life from daily routines to emotional states. It is essential for individuals experiencing these tremors to seek medical advice to address both the physical and psychological effects. Adjusting medications, when possible, and exploring therapeutic strategies can help manage the tremors and improve quality of life. A variety of treatment options for essential tremor are available today which makes it possible, but also necessary, to select the most appropriate solution for the individual patient.

• Nicotine can cause tremors.3 Therefore, smoking a blunt or consuming nicotine alongside cannabis could contribute to a twitchy feeling.
• Dealing with tremors that arise as a side effect of medication requires a collaborative and strategic approach, drawing on the expertise of healthcare providers and the active participation of patients.

Tardive Dyskinesia

The shaking movement created by tremors is usually quick and tends to occur in cycles lasting six to 10 seconds. Drug-induced tremors may also be referred to as drug-induced Parkinson’s (DIP). In fact, 10 percent of Parkinson’s cases at a Parkinson’s disease treatment center turned out to be DIP.

A double-blind placebo-controlled crossover study conducted by Hellriegel et al. 11, investigated the efficacy of levetiracetam in comparison to placebo in twelve patients. At the beginning, the patients received 500 mg levetiracetam twice a day, with the dosage subsequently escalated to a maximum of 3000 mg per day for those whose renal function could tolerate such high doses. The primary endpoint of the study was the time to onset of instability in standing position.

Lifestyle Quizzes

Exceptions include tremor secondary to valproate, which can appear at therapeutic or during stable treatment, or, rarely, tardive tremor. Tremor can occur secondary to many drugs, including SSRIs, lithium, tricyclic antidepressants, antiepileptics (particularly valproate), bronchodilators, amiodarone and immunosuppressives. Another underlying aetiology, such as Parkinson’s disease, essential tremor or hyperthyroidism, needs to be excluded. One limitation in the comparison of these studies lies in the inconsistent diagnostic criteria employed.

Other movement disorders

CT and MRI scans are done by a computer and allow your doctor to see your brain. Using these scans, your doctor can potentially rule out defects in your brain that may be causing tremors. If the benefit of the medicine is greater than the problems caused by the tremor, your provider may have you try different dosages of the medicine.

Do I have carpal tunnel syndrome?

DIMDs are often underrecognized, and knowledge of DIMDs will allow clinicians, pharmacists, and other health care professionals to better identify and manage patients with these conditions. Dystonia, or involuntary muscle contractions that cause abnormal postures or twisting movements, affects 10-20% of patients with medication-induced movement disorders. It is often seen in patients taking antipsychotic or anti-nausea medications. Dystonia can affect any part of the body, including the neck, face, or limbs. These contractions can be painful and may interfere with daily activities. Dystonia is believed to result from an imbalance in neurotransmitters, particularly dopamine, which leads to abnormal muscle control.

No good evidence exists regarding the management of tardive drug-induced movement disorders.15 Treatment usually consists of withdrawing the offending drug, and a trial of a combination of drugs. Resuming the offending drug or changing to an atypical antipsychotic is sometimes required.16 In patients with a chronic psychotic disorder clozapine is preferred. Most recently, vesicular monoamine transporter 2 inhibitors deutetrabenazine and valbenazine have been proposed as treatment options.17,18 Other oral drugs have been tried, including tetrabenazine, amantadine and propranolol. The frequency of a tremor can be approximated by observation with the naked eye, and more accurately measured with surface electromyography. 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 any concerns or questions about laws, regulations, or your health, you should always consult with an attorney, physician or other licensed professional. So, it may not be just the form of cannabis (edibles or otherwise) that makes muscle tension feel worse, but the frequency and dosage that aggravates the pain. Terpenes, the aromatic molecules in cannabis and other plants, may also contribute to the overall positive effects of cannabis. Specific studies on terpenes’ impact on muscle tension and spasms are ongoing.

Asthma Medicines

In rare cases, a medicine such as propranolol may be added to help control the tremor. There were no conflicts of interest to declare relevant to this study. Focusing on pain-relieving CBD and lower THC may avoid aggravating pain sensations. THC, the active ingredient in cannabis, can change how our body responds to the environment. Other brain networks involved may include those regulating emotions, sensation awareness and interpretation. One key network, called the “self-agency” network, helps you feel in control of your movements.

Consuming low to moderate doses might provide relief, whereas higher doses could worsen muscle pain. Dr. Kessler cautions, “We do have some research that suggests high doses of THC can cause pain symptoms to worsen, which is why starting at low doses if you’re taking edibles is important.” Some, like dehydration or an overused muscle, are usually easy to pinpoint and can be corrected with hydration, electrolytes, or rest. Other more severe causes, like multiple sclerosis or ALS, require a medical diagnosis and treatment. Tremors usually begin in adolescence (between ages 10 and 19) or middle age (between 40 and 50), according to the National Institute of Neurological Disorders and Stroke, but can appear at any time.

According to Johns Hopkins Medicine, essential tremor is most common in people older than 65. Medication-induced hand tremors, though often overlooked as a minor side effect, can significantly impinge on a person’s daily functioning and overall well-being. For enhanced physiologic tremor, you may just need to cut back on caffeine or manage stress. Tremors caused by thyroid disorder or alcohol withdrawal may be reduced by treating those conditions. This resting, pill-rolling tremor can occur with or without the degenerative neurological condition Parkinson’s disease.

The patient’s subjective experience of the tremor’s severity and the degree of impairment and disability that it causes in what medications cause tremors the patient’s life are more important than the objective assessment during the patient’s clinic visit. The nonpharmacologic treatment options outlined above are considered for all patients with essential tremor. As with other movement disorder symptoms, the severity of a patient’s tremor may wax and wane considerably over time, and is influenced by the patient’s emotional state.

ACTIONS

The frequency in the electrophysiologic activity on the left and on the right side differs slightly, with 13 activations in the left anterior tibial muscle, but only 12 in the right side during the period represented in the figure. This indicates that tremors originate in separate circuits in the left and right sides, and the overall picture underscores the central origin and complex nature. In the outpatient setting, the clinical features and neurologic examination findings are the most important assessment tools in evaluating patients with tremor. For routine evaluation, thyroid function tests are performed in most or all patients with tremor to exclude hyperthyroidism. In patients under 55 years, serum and urine tests for Wilson’s disease may be indicated. It is interesting to note that Raethjen et al.10 published the first work that demonstrated a definitive effect on the central component of physiological tremor by any drug (amitriptyline) in 2001.

Although the opposite may be true, generally action tremors will be more severe during an office visit (which usually is accompanied by some uneasiness or anxiety), and tremors at rest will become less obvious or not visible at all. Thus, observations made during a short office visit may be misleading, and information from the patient (or proxy) is important. Assessment of a patient with tremor starts with the characterization of the tremor phenomenology, which narrows down the differential diagnosis and often can establish a diagnosis. 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.
