Tremor or Shaking
Hands | - Others | Tremor or Shaking (Symptom)
The hand tremor is due to the small muscle fibers located in our hands and arms constantly contract and relax at random. It becomes a problem when the tremors of the hands begin to interfere with writing, when holding a cup of coffee or a knife, etc. When people see that their hands are unstable, they often begin to worry that this necessarily the symptoms associated with Parkinson's disease, but usually this is not always the case.
Tremor is generally caused by problems in parts of the brain that control muscles throughout the body or in particular areas, such as the hands. Neurological disorders or conditions that can produce tremor include multiple sclerosis, stroke, traumatic brain injury, and neurodegenerative diseases that damage or destroy parts of the brainstem or the cerebellum. Other causes include the use of some drugs (such as amphetamines, corticosteroids, and drugs used for certain psychiatric disorders), alcohol abuse or withdrawal, mercury poisoning, overactive thyroid, or liver failure. Some forms of tremor are inherited and run in families, while others have no known cause.
Among the most common causes of shaking hands are: (i) anxiety, (ii) low blood sugar causes shakiness because the nerves and muscles are deprived of fuel, (iii) Essential tremor is one of the most common types of tremors, the fibers contract and relax together (timing), resulting in more noticeable movements.
