Why do elderly people experience hand tremors?

Possible causes of hand tremors in the elderly may include multiple factors, primarily summarized as follows: 1. Physiological tremor: Caused by environmental stimuli, excessive tension, or fatigue, usually does not affect daily life and work, and can be relieved after rest. 2. Parkinson's disease: This is a common neurodegenerative disorder, where hand tremors often manifest as resting tremors, accompanied by symptoms such as bradykinesia and increased muscle tone. 3. Essential tremor: Related to environmental factors and nervous system abnormalities, it may increase nerve excitability, leading to hand tremors. Symptoms can be controlled with appropriate medications during treatment. 4. Hyperthyroidism: Due to excessive secretion of thyroid hormones, it may cause an accelerated metabolism, resulting in symptoms such as hand tremors and palpitations. Thyroid function tests and treatment are required. If the symptom of hand tremors persists or worsens, prompt medical attention is recommended.
