What Causes Tremors In Stroke Patients

Stroke is a complex medical issue, also the aftereffects of stroke are even worse than that, the common challenge faced by stroke survivors is tremors. But you may think that both tremor and stroke are two different conditions, why do they overlap? If you are curious, read on to uncover the science behind the tremors in stroke patients and know how it can be managed. 

Why do stroke patients experience tremors? 

Typically, tremors are involuntary, rhythmic muscle movements that may lead to shaking in various parts of the body. Several stroke patients experience tremors due to the damage to the brain. Further, the frequency of tremors in stroke patients differs from person to person like some individuals may experience mild shaking, while others may have visible, uncontrollable movements. 

Even researchers have shown that tremors in stroke patients are common, notably when a few regions of the brain that are responsible for movements are disturbed. Also, you need to understand that not all stroke survivors will experience tremors. However, these tremors in stroke patients will delay the process of the recovery journey. Whenever facing stroke and tremor together, consider visiting the nerve doctor in Coimbatore for better outcomes. 

What types of tremors in stroke patients are common? 

Not all tremors are the same, they come in distinct forms based on the movement patterns and the areas of the brain that have been affected. 

– Resting tremors: These type of tremors in stroke patients occurs when an individual is at rest and not trying to move. Also, the shaking subsides when they try to do some actions. 

– Postural tremors: This type of tremor occurs when an individual is trying to maintain a position, like holding their arm out straight. Stroke and tremors patients find it difficult to keep their limbs steady when trying to stay still. 

– Intention tremors: When an individual is trying to grab something, this tremor will occur. 

– Action tremors: When an individual tries to move actively or perform tasks, this tremor will occur. This will disturb your daily activities like eating or writing. 

Why do tremors occur after a stroke? 

The brain plays a crucial role in tremors in stroke patients because it controls voluntary movements. When the regions that are responsible for motor functions are impaired, the signal between the brain and muscles can become disrupted. This results in irregular muscle contractions, that is tremors. Simply, the human brain is an intricate organ, so even small changes can affect the body’s movements. 

These basal ganglia are a bunch of structures deep within the brain, and it’s mainly involved in controlling movement. When a stroke strikes this region, it can result in tremors because the brain struggles to regulate smooth, purposeful movements. 

How does the cerebellum affect tremors? 

The cerebellum is also referred to as the little brain, which plays a crucial role in fine-tuning movements and maintaining balance. In case there is any damage to the cerebellum during the stroke, it can also lead to intentional tremors in stroke patients, when small movements like reaching for an object become hard and difficult to control. 

Further, certain factors will trigger the likelihood of tremors in stroke patients: 

  • Age: Elderly stroke patients are more prone to tremors. 
  • Pre-existing neurological conditions: If an individual already experienced conditions like Parkinson’s disease, they are at the highest risk. 
  • Severity and location of the stroke: There are certain complex regions in the brain like basal ganglia and cerebellum, if they are affected they are more prone to experience tremors.

What diagnostic and treatment methods for stroke-related tremors? 

To get the correct treatment, an accurate diagnosis is crucial. Neurologists employ numerous tools, like MRI and CT scans, to diagnose the area of the brain affected by the stroke. Further, they observe the patterns to classify them like resting or intention tremors. 

The treatment for stroke patients varies based on the severity and type: 

– Physical therapy for tremor management: The first line of treatment to manage tremors is physical therapy. Further, therapists play a crucial role in assisting patients in regaining their strength and coordination, at times it will reduce the severity of tremors. 

– Medications to control tremors: Certain medications greatly assist in reducing the tremor frequency and intensity. Also, medications cannot offer complete relief but will assist a few patients. 

– Assistive devices to manage tremors: Individuals with severe tremors can benefit by using utensils or braces, which can make their daily tasks easier. These tools assist in stabilizing the hands and reduce the impact of shaking. 

– Surgical interventions: In rare cases where tremors severely disturb the quality of life, deep brain stimulation (DBS) might be considered. In DBS a device will be implanted in the brain that sends electrical impulses to regulate abnormal movement signals. 

These are the holistic stroke treatment in Coimbatore, your doctor will cater a treatment plan based on your condition. 

Can tremors be prevented? 

No one can give assurance that tremors in stroke patients can be preventedz, but timely detection and comprehensive rehabilitation can make a huge difference. Physical therapy, medications, and lifestyle changes may assist in reducing or minimizing their severity. 

Further, tremors can last for weeks to years, depending on the patient’s recovery progress and the area of the brain affected. In a few cases, tremors can be minimized over time, but for others, they can persist for some time. 

The practical tips to manage tremors include: 

  • Use heavy utensils to stabilize your hand movements. 
  • Engage in relaxation techniques to reduce the intensity of the tremor. 
  • Try adaptive tools like grab bars or non-slip mats to simplify your daily tasks. 

Final thoughts: 

In conclusion, we can say that tremors post-stroke are one of the common conditions and also a side effect of brain damage. When they affect the quality of your life, the appropriate treatment and support can help manage them effectively. By being aware of the causes, types, and treatments of tremors, stroke survivors and their families can take possible steps toward improving their quality of life.
