Caring for a loved one living with dementia often brings unexpected challenges, and tremors—uncontrolled, rhythmic movements—may be one of them. Tremors can make everyday tasks harder and raise questions about what’s causing them. While some tremors are related to the type of dementia your loved one has, others may stem from separate medical issues or even side effects of medications.
By understanding the potential causes of tremors and learning how to address them, you can better support your loved one and help them stay safe and comfortable.
Common Causes of Tremors in Dementia
Tremors can have various origins, including the progression of dementia, underlying health conditions, or the effects of medication. Here’s a closer look at each possibility:
The Dementia Itself
Not all types of dementia cause tremors, but certain forms are more likely to include them:
- Lewy Body Dementia often causes physical symptoms like tremors, stiffness, or difficulty with movement because it shares similarities with Parkinson’s disease.
- Parkinson’s Disease Dementia starts as Parkinson’s and progresses to include dementia, with tremors being a hallmark symptom.
- Vascular Dementia can sometimes lead to tremors if the parts of the brain controlling movement are affected by reduced blood flow.
While tremors might occur with other forms of dementia, they’re less common unless motor functions are specifically impacted.
Medications
Some medications used to manage dementia symptoms or related conditions can cause tremors as a side effect. These include:
- Antipsychotics, antidepressants, and mood stabilizers, often prescribed for behavior changes or mood swings, which may lead to shaky movements.
- Anti-seizure medications, sometimes used in dementia care for mood regulation, can also contribute to tremors.
If medication is suspected, it’s important to consult a doctor before making changes. Adjusting the dosage or switching medications can sometimes resolve the issue.
Other Medical Conditions
Tremors may also be caused by unrelated health conditions that coexist with dementia, such as:
- Essential tremor, a common movement disorder that’s not related to dementia but can occur alongside it.
- Thyroid problems (e.g., hyperthyroidism), which can affect motor control and lead to trembling.
- Vitamin deficiencies, such as low levels of B12, which can cause neurological symptoms, including tremors.
A thorough evaluation by a healthcare provider can help identify and treat these conditions if they’re contributing to the tremors.
What You Can Do to Help
Tremors can make daily life more difficult for your loved one, but there are practical steps you can take to address the issue and maintain their quality of life:
Talk to a Doctor: The first step is understanding what’s causing the tremors. A healthcare provider can evaluate whether they’re related to the type of dementia, a side effect of medication, or another condition. Adjustments to treatment or additional therapies may help.
Simplify Everyday Tasks: Tremors can interfere with activities like eating, dressing, or drinking, but tools and strategies can make these tasks easier:
- Use weighted utensils or plates with edges to prevent spills while eating.
- Offer cups with lids or straws to make drinking less frustrating.
- Provide clothing with Velcro fasteners or elastic waistbands to simplify dressing.
Reduce Stress: Stress and anxiety can worsen tremors. Encourage calming activities, such as listening to soft music, spending time outdoors, or engaging in a favorite hobby. A consistent daily routine can also provide a sense of stability and reduce stress.
Support Their Confidence: Tremors can sometimes embarrass or frustrate your loved one. Offer reassurance and adapt routines as needed to help them feel more at ease. For example, if holding utensils is difficult, finger foods can be a helpful alternative.
Focus on Safety: Tremors can increase the risk of accidents, especially during tasks that require coordination. Be sure to monitor activities closely and adjust the environment to minimize hazards. For example, use non-slip mats on tables and in bathrooms.
When to Seek Immediate Help
If tremors come on suddenly, worsen quickly, or are accompanied by other changes—like confusion, weakness, or fever—contact a healthcare provider right away. These could be signs of a serious issue, such as an infection or stroke, that requires urgent attention.
Tremors in someone with dementia can stem from many causes, including the progression of the condition, other health issues, or medication side effects. By working closely with healthcare providers and making thoughtful adjustments at home, you can help your loved one manage tremors and maintain their dignity and comfort. Caregiving is a journey with many challenges, but with the right support and resources, you can navigate this aspect with confidence and care.
