Does a hand tremor mean Parkinson’s disease, or are there other causes?
Normal hand tremor may become more noticeable with anxiety, fatigue, caffeine or some medicines. Essential tremor and other conditions can also cause shaking. Tremor alone does not diagnose Parkinson’s disease; rest versus action patterns and daily impact guide assessment.

What should you observe?
Record onset, whether one or both hands shake, and whether it occurs while writing, holding a cup or resting. Mention family history, medicines, stimulants and symptoms such as slowed movement, palpitations or weight change.
Useful steps without self-treatment
Reducing caffeine and improving sleep may help when these trigger symptoms. Do not stop prescribed medicines, start tremor drugs yourself or use alcohol as treatment. Examination determines whether blood tests or neurological review are needed.
When review should be faster
Book assessment if shaking worsens or interferes with eating, writing or work. Sudden onset with weakness, speech disturbance or major balance problems needs urgent care; new neurological symptoms should not simply be attributed to anxiety.
