Shaking hands, also known as tremors, can indicate a serious problem, but this is not always the case; tremors can be symptomatic ofParkinson's disease, Graves' disease or Huntington's disease, according to Healthline. Tremors can also be a symptom of several medical emergencies, including alcohol withdrawal delirium, sepsis, severe acute respiratory syndrome (SARS), and overdose of adrenergic bronchdilators that results when someone uses too much of an inhaled asthma or bronchitis medication.
Essential tremor can be a symptom of neurodevelopmental disorders, including autism. Tremors can also be induced by drugs or alcoholism, or drug or alcohol abuse. Because it affects the central nervous system, multiple sclerosis, which is a chronic autoimmune disease, can also cause tremors. Fetal alcohol syndrome can cause tremors in those born with it.
Some rare diseases and conditions can also cause hand shaking or tremors. Phenylketonuria, which is a rare conditioncharacterized by the body's inability to break down an essential amino acid known as phenylalanine, can cause hand shaking. A very rare form of partial albinism known as Chediak-Higashi syndrome, or CHS, can also cause problems with the nervous and immune systems, including tremors. The rare but inherited neurological disorder Hallervorden-Spatz disease, which can be fatal, also causes tremors and hand shaking.
