What Causes Tremors in Older People?

Tremors in Older People

Tremors in older people can be caused by various factors, including:

  • Essential Tremor: Essential tremor is one of the most common causes of tremors in older adults. It typically affects the hands, but it can also affect the head, voice, or other parts of the body. Essential tremor tends to run in families and may worsen with age.
  • Parkinson’s Disease: Parkinson’s disease is a neurodegenerative disorder that commonly causes tremors, along with other symptoms such as rigidity, bradykinesia (slowed movement), and postural instability. Tremors in Parkinson’s disease often start on one side of the body and progress over time.
  • Medication Side Effects: Certain medications, particularly those used to treat psychiatric disorders such as antidepressants, antipsychotics, or mood stabilizers, can cause tremors as a side effect. Other medications, such as certain asthma drugs or stimulants, can also contribute to tremors.
  • Stroke: Stroke or other cerebrovascular accidents can damage areas of the brain responsible for motor control, leading to tremors, weakness, or other neurological symptoms.
  • Alcohol Withdrawal: Tremors can occur as a withdrawal symptom in individuals with alcohol use disorder who abruptly stop drinking alcohol. These tremors, known as alcohol withdrawal tremors or alcohol withdrawal syndrome, typically occur within 6-24 hours after the last drink.
  • Neurological Disorders: Other neurological conditions, such as multiple sclerosis, Huntington’s disease, or Wilson’s disease, can cause tremors as a result of damage to the nervous system.
  • Thyroid Disorders: Hyperthyroidism, an overactive thyroid gland, can cause tremors as a result of excess thyroid hormone affecting the nervous system.
  • Hypoglycemia: Low blood sugar levels (hypoglycemia), particularly in individuals with diabetes, can cause tremors, along with other symptoms such as sweating, confusion, and weakness.
  • Age-Related Changes: Normal aging can lead to changes in muscle control and coordination, which may contribute to tremors in older adults, although these tremors are typically mild and not disabling.
  • Other Causes: Tremors can also be caused by factors such as stress, fatigue, caffeine consumption, or dehydration, although these tremors are usually temporary and resolve with rest or hydration.

If you or someone you know is experiencing tremors, particularly if they are persistent or affecting daily activities, it’s important to consult with a healthcare professional for proper evaluation and diagnosis. Treatment for tremors will depend on the underlying cause and may include medication, physical therapy, lifestyle modifications, or other interventions tailored to individual needs.
