What is the difference between the abnormal signal of hand tremor and Parkinson's disease?

The natural tremor often worsens with age, and can suffer from severe hand or head tremors in daily life. In many cases, people do not recognize the symptoms of trembling in the head, but they listen to the stories of their surroundings and know them. Therefore, they become conscious of other people's eyes and may shrink psychologically when symptoms worsen.
Diseases that can be suspected of hand tremors include natural tremors and Parkinson's disease. Both diseases cause hand tremors, but the patterns and treatments of tremors are different. Hand tremors caused by Parkinson's disease usually occur when stabilized, and if you move with intention or do something else, the tremors are somewhat alleviated. On the other hand, if you have no symptoms when you are still and your hands shake when you write or eat, it is highly likely to be your natural tremor.
Intrinsic tremors usually result in tremors in both hands, while Parkinson's disease begins to tremble first in one hand. In addition, the hand trembles up and down, and Parkinson's disease trembles back and forth. There is also a difference in age groups, but essential tremors occur at all ages, while Parkinson's disease is mainly for the elderly aged 60 or older.
In most cases, essential tremors can relieve symptoms with medications. If you are refractory to drugs or have a disability in your daily life due to severe tremors, you may consider performing deep brain stimulation. Although essential tremors are a disease that must be managed for life, the progress is relatively good because no other complications have occurred.
In the diagnosis process of essential tremors, it is also important to identify other diseases that can cause tremors, such as hyperthyroidism, decreased renal or liver function, drugs, peripheral neuropathy, or wrist tunnel syndrome. To this end, you can carefully identify the drugs you are taking, perform blood tests and brain MRI tests, and evaluate the severity through spiral drawing tests.
Parkinson's disease patients exceeded 140,000 in 2023. Parkinson's disease is the second most common degenerative brain disease after dementia and is a fatal disease for the elderly, characterized by motor symptoms such as muscle hardening, bradykinesia, and unstable walking posture, constipation, autonomic neurological symptoms, REM sleep disorders, and depression.
Parkinson's disease is found to be caused by the gradual loss of dopamine neurons in the dark matter in the midbrain, so administering drugs such as dopamine precursors (L-dopa) or dopamine enzymes can improve motor symptoms. However, Parkinson's syndrome has similar symptoms to Parkinson's disease, but the main damaged area of the brain is different, so the response to the drug is not good.
Son Sung-yeon, head of the neurology department at Seran Hospital, said "If only one hand trembles while lying still or sitting, it is likely to be Parkinson's disease, and when writing or using chopsticks. If both hands tremble more clearly when the hand is stretched forward, it is possible that it is the natural tremor. "In addition, some constipation drugs, antidiarrheal drugs, or neuropsychiatric drugs, including depression drugs, can also cause tremors, so check all drugs you are taking.", he explained.
Director Son Seong-yeon then explained, "Intrinsic tremors tend to be genetic, worsen with age, and symptoms are likely to be worsened by anxiety, stress, and caffeine."If you often walk due to narrow steps, tremors are observed when walking or resting, and you feel unpleasant feelings in your limbs, you should keep in mind the possibility of Parkinson's disease. It is recommended to seek medical attention from a neurologist, diagnose accurately through objective tests such as brain MRI and PET-CT if necessary, and start treatment early."
