What causes hand tremors in the elderly?

There are many causes of hand tremors in the elderly. Some are physiological and generally do not lead to serious consequences, while others may be due to underlying diseases such as hyperthyroidism, hypoglycemia, or Parkinson's syndrome. The specific analysis is as follows:

I. Physiological factors

Hand tremors in the elderly can occur due to external stimuli such as significant emotional fluctuations, cold exposure, or excessive fatigue. Symptoms usually subside with proper warmth, adequate rest, and emotional relaxation, and typically do not require special treatment.

II. Pathological factors

1. Hyperthyroidism

In elderly individuals with hyperthyroidism, excessive secretion of thyroid hormones increases overall metabolism and neural excitability, raises muscle tone, and leads to hand tremors. Patients should follow medical advice for drug treatment, such as methimazole, carbimazole, or propylthiouracil.

2. Hypoglycemia

Insufficient sugar intake, excessive consumption, or inappropriate medication use in diabetic patients can cause hypoglycemia in the elderly. This triggers increased adrenaline secretion, resulting in sympathetic nervous system activation, muscle twitching, hand tremors, and muscle weakness. Prompt sugar supplementation is required.

3. Parkinson's syndrome

Elderly individuals may develop Parkinson's syndrome due to cerebrovascular disease, infections, poisoning, or other causes, leading to hand tremors. Timely pharmacological intervention is necessary, including medications such as entacapone tablets, trihexyphenidyl hydrochloride, or levodopa-carbidopa.

If hand tremors in the elderly persist over a long period, occur frequently, or worsen rapidly, prompt medical evaluation and detailed examination are essential.
