This understanding helps guide treatment approaches that focus on education, rehabilitation, psychological support and lifestyle adjustments to improve symptoms and your overall well-being. Ask your provider if it is OK to take over-the-counter medicines that contain stimulants or theophylline. Theophylline is a drug used to treat wheezing and shortness of breath. Several family members on my father’s side have essential tremor, including my aunt and cousin, so I am part of the majority. “Essential tremor is highly, highly heritable,” says Debra J. Ehrlich, M.D., director of the Parkinson’s Disease Clinic at the National Institute of Neurological Disorders and Stroke. In fact, about half of all essential tremor cases are inherited, according to Mayo Clinic; however, the genetic mutations and variants responsible are still unknown, Ehrlich says.
What triggers functional movement disorder?
“More studies and data are needed to assess its effectiveness across a broader range of patients,” says Sharma, who was not involved in the new research. Krehbiel was the first participant to enroll in a clinical trial testing a new form of deep-brain stimulation (DBS), a technology that gained approval from the U.S. Food and Drug Administration for Parkinson’s tremor and essential tremor in 1997 (it was later approved for other symptoms and conditions). The new adaptive system adjusts stimulation levels automatically based on the person’s individual brain signals. It depends on the type of abnormal movements and other factors unique to you. Your healthcare team will give you a better idea of what to expect.
Many tremors are a result of neurological disorders or nervous system diseases causing hyperkinetic movements, which refer to abnormal, excessive, and involuntary movements. In addition to these disorders, certain medications can cause drug-induced tremors. Please keep reading to find out which commonly prescribed medications can cause hand tremors as a side effect. Your doctor may reduce your medication dose or stop the offending drug and then switch you over to a different medication. If it is not possible to stop a medicine, your doctor may prescribe an additional medication to control the rhythmic shaking. A medication called tetrabenazine is sometimes prescribed to patients with a severe type of tremor called tardive tremor that occurs due to the long-term use of certain psychiatric drugs.
Exams and Tests
Unlike traditional surgical interventions, Focused Ultrasound allows patients to return home the same day with little to no recovery time. Your doctor will ask you for a list of medications you are taking, what medications cause tremors paying special attention to any new drugs that could be causing your symptoms. There are exceptions to the “rest” versus “active” rule , Louis cautions, so if you have a tremor that concerns you, make an appointment with a movement disorder neurologist for a diagnosis. 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.
The main difference between drug-induced tremor and essential tremor is that the exact mechanism and cause of essential tremor are not known. Another difference between these two types of tremor is that drug-induced tremor tend to be quick and usually occur in cycles that last about 10 seconds. While you must be at least 22 years old, there is no upper age limit. If you meet the eligibility requirements, can fit into an MRI scanner, and have essential tremor or tremor-dominant Parkinson’s disease, you are eligible for this life-changing procedure. With Focused Ultrasound, patients like Mr. Kircher can receive life-changing treatment without incisions, anesthesia or permanent implants. The procedure uses MRI-guided sound waves to target and treat the source of the tremor in the brain, providing almost immediate relief.
- Do not stop taking any medicine without first talking to your provider.
- Talk to your doctor about the medications you’re taking, and consult them before adding any new over-the-counter medications.
- This resting, pill-rolling tremor can occur with or without the degenerative neurological condition Parkinson’s disease.
- Blood tests and imaging studies (such as a CT scan of the head, brain MRI, and x-rays) are usually normal.
- Tardive dyskinesia is a late-onset movement disorder that affects around 20-30% of patients who have been on long-term antipsychotic medications.
- While resting tremors are common in patients with Parkinson’s disease, they are not as common in pseudoparkinsonism.
Recognizing that exercise helps slow down progression, Lipp wanted “to be as proactive as possible.” He ran his first marathon in 2016. “In the course of training, I lost weight, got stronger, and, ironically, got in the best shape of my life,” he says. Not all therapists are familiar with FMD, so it’s best to see a therapist who has experience treating FMD. Other brain networks involved may include those regulating emotions, sensation awareness and interpretation.

HCN Medical MemoRegular monitoring and patient education are essential in managing medication-induced tremors, ensuring therapeutic efficacy while minimizing adverse effects. If you develop tremor — or an existing tremor gets worse — after starting a medication, tell your healthcare provider. Contact your provider if you are taking a medicine and a tremor develops that interferes with your activity or is accompanied by other symptoms. Severe tremor can interfere with daily activities, especially fine motor skills such as writing, and other activities such as eating or drinking. Tricyclic antidepressants like amitriptyline can cause tremor progression or an increase in tremor amplitude or tremor severity, i.e., it can make a tremor more noticeable.

The movements look like trembling or shakiness and can range from mild to severe. Rarely a medicine like propranolol, used to treat essential tremor, may be prescribed to control a medication-induced tremor. Treatments like deep brain stimulation and surgery are usually reserved for severe tremors that do not respond to other therapies. Talk to your doctor if you notice symptoms of tremors while on medication for high blood pressure.
It can be an action tremor that occurs when you try to do simple tasks like picking up something or drinking from a glass. While it is not life-threatening, many patients find an essential tremor affects their quality of life. For decades, Keith Krehbiel took high doses of medications with a debilitating side effect—severe nausea—following his diagnosis with early-onset Parkinson’s disease at age 42 in 1997. When each dose wore off, he experienced dyskinesia—involuntary, repetitive muscle movements.
How doctors diagnose functional movement disorder
These abnormal movements aren’t caused by damage to your brain, spinal cord or nerves. However, this doesn’t mean nothing is wrong or that the condition isn’t real. This is similar to a computer with fully working hardware but malfunctioning software. A tremor that occurs when the muscles are relaxed or that affects the legs or coordination may be a sign of another condition, such as Parkinson disease. The speed of the tremor can be an important way to determine its cause.
Patient involvement in management
Being diagnosed with and treated for drug-induced parkinsonism can be a long journey. The diagnostic process may involve several tests and a lot of waiting. Find ways for stress relief, including connecting with loved ones, performing gentle physical activity, and meeting with a licensed therapist.
Health Conditions
Medication-induced movement disorders occur when certain medications interfere with the brain’s ability to regulate movement. These disorders can manifest as involuntary muscle contractions, tremors, or difficulty with coordination. The most common types of MIMDs include tardive dyskinesia, drug-induced parkinsonism, and akathisia. Tardive dyskinesia, for example, is characterized by repetitive, jerky movements, often in the face or limbs. Drug-induced parkinsonism mimics Parkinson’s disease symptoms, such as stiffness and slow movements. Dystonia, or involuntary muscle contractions that cause abnormal postures or twisting movements, affects 10-20% of patients with medication-induced movement disorders.
Anticonvulsant drugs are among the most common causes of drug-induced tremors. Anticonvulsants are used for a variety of medical conditions, including epilepsy and bipolar disorder. Bronchodilators, which are commonly used in the treatment of conditions such as asthma, can also cause tremors.

Immunosuppressants, which are used to prevent the rejection of transplanted organs, can also lead to drug-induced tremors. Drugs used to treat a variety of psychiatric disorders such as antipsychotics, lithium, and certain antidepressants are also potential causes of drug-induced tremors. Caffeine is a stimulant that can also cause you to have tremors or can worsen existing tremors. If you cannot discontinue the medicine that is causing your tremor, your healthcare provider may change your medication dose or switch you to another medicine to treat your health condition. Placed under the skin of the chest, a DBS device transports electrical signals through very thin wires to an area in the brain that controls movement. Because FMD isn’t caused by permanent brain damage, your brain has the potential to “relearn” movements.
