What causes trembling in elderly people?

Generally, tremors in the elderly may be caused by natural aging, excessive fatigue, hyperthyroidism, Parkinson's syndrome, coronary atherosclerotic heart disease, and other conditions. Treatment under medical guidance may include general management and medication. Specific analyses are as follows:

1. Natural Aging

With increasing age, the nervous and muscular systems of older adults gradually degenerate, which may reduce muscle control and lead to mild trembling in the hands or body. Maintaining a healthy lifestyle with balanced nutrition and adequate sleep is recommended.

2. Excessive Fatigue

After prolonged physical or mental exertion, muscles and the nervous system may become fatigued, leading to unstable muscle control and resulting in tremors. It is important to ensure sufficient rest and avoid overexertion.

3. Hyperthyroidism

Hyperthyroidism occurs when the thyroid gland produces excessive thyroid hormones, causing increased metabolic activity and sympathetic nervous system excitation. Excess thyroid hormones can overstimulate the muscles and nervous system, leading to tremors. Symptoms may also include increased appetite with weight loss, and exophthalmos (protruding eyes). Patients should follow medical advice to take medications such as methimazole tablets, propylthiouracil tablets, and metoprolol tablets.

4. Parkinson's Syndrome

Parkinson's syndrome is a neurodegenerative disorder characterized primarily by resting tremor, bradykinesia (slowness of movement), muscle rigidity, and postural instability. Degeneration and loss of dopaminergic neurons in the substantia nigra may lead to reduced dopamine levels in the striatum, causing tremors. Additional symptoms may include bradykinesia, postural imbalance, and masked facies. Medications such as levodopa tablets, pramipexole hydrochloride tablets, and selegiline hydrochloride tablets should be used as directed by a physician.

5. Coronary Atherosclerotic Heart Disease

Coronary atherosclerotic heart disease is a cardiac condition caused by atherosclerosis of the coronary arteries, leading to narrowed or blocked vessels and resulting in myocardial ischemia or infarction. Atherosclerosis-induced myocardial ischemia and hypoxia impair the heart’s pumping function, indirectly causing generalized or localized muscle tremors. Common accompanying symptoms include chest pain, palpitations, shortness of breath, and dyspnea. Treatment under medical supervision may include aspirin enteric-coated tablets, atorvastatin calcium tablets, and sustained-release isosorbide mononitrate tablets.

In daily life, it is important to maintain regular作息 (sleep-wake cycles), balanced nutrition, moderate exercise, and avoid excessive fatigue to support overall health and reduce physical discomfort caused by various factors.
