Risk factors Risk factors for<unk>  include excess exposure to heavy metals, such as mercury and lead, as well as an increased intake of various drugs and toxins. Researchers found that raising the dose of antidepressants or neuroleptics elevate the risk for developing<unk> . Increasing intake of coffee, tea, or other stimulants can also cause for greater risk of development. Tremors depend on dosage and amount of exposure to these factors and will typically decrease dramatically if the intake is reduced. Hyperthyroidism and hyperglycemia also increase the likelihood of developing<unk> . Triggers Similar to the causes of most tremors,<unk>  is triggered by lesion damage to a circuit controlling a physiological task such as precision movements, motor learning, the control of muscle groups, etc.<unk>  specifically occurs as a delayed reaction to lesion damage of the dopaminergic and cerebellothalamic systems. The most common cause of this lesion damage is brainstem stroke and trauma. The lesion damage to the dopamine pathways is associated with the neurological signs and symptoms. Genetics/Genome Because brainstem stroke and lesions are typically the causes of<unk> , there is little research supporting a genetic factor to the disease. However, one could be more susceptible to developing<unk>  if there is a familial history of stroke, substance abuse, or other disorders that increase risk.
