Understanding Tremors in Older Adults

Today we are discussing a symptom that is becoming increasingly common among older adults: tremors.

A tremor is the most common type of movement disorder. It is defined as an involuntary, rhythmic movement of a body part, most often affecting the hands.

Common Types of Tremors

1. Physiological Tremor
This is the most common form of tremor and can occur occasionally in otherwise healthy individuals. It is typically a fine shaking movement that may appear during:

• Stress or anxiety.
• Caffeine intake
• Side effects of certain medications

2. Essential Tremor
This type is known as an action tremor, meaning it occurs during voluntary movement such as:

• Holding a cup
• Writing
• Using utensils

Essential tremors usually affect both sides of the body and may worsen with stress or caffeine. Fortunately, medications are available to help manage symptoms.

3. Parkinson’s Disease Tremor
This is a resting tremor, meaning it occurs when a body part is relaxed and not in use. A common early sign is a thumb or hand movement while resting in the lap.

Characteristics may include:

• Often begins on one side of the body.
• May spread to the opposite side over time.
• It can eventually affect walking, balance, and memory.

What Causes Tremors?

Tremors can result from a wide range of conditions, including:

• Medical diseases or neurological disorders
• Medication side effects
• Exposure to certain toxins
• Genetic or unknown causes

Evaluation and Treatment

A medical evaluation may include:

• Detailed medical history
• Physical examination
• Laboratory testing
• Imaging studies

There are several treatment options available depending on the cause and severity.

When to Seek Medical Care

If you or a loved one is experiencing tremors or changes in movement, evaluation by a primary care provider or neurologist is recommended. Early assessments can help identify the cause and guide proper treatment.
