Hello my friend Thanks for your question on HCM Essential tremor is known to be an familial condition, meaning that it runs in families. At least 5-7 out of 10 people with essential tremor have other members of the family with the same condition. Genes are passed on to a child from each parent and determine what we look like, how our body functions and even what diseases we get. Particular genes have been shown to have certain changes present in families with essential tremor It is not clearly understood how this genetic change leads to essential tremor. However, it is likely that it somehow affects some parts of the brain that are responsible for controlling movement. Essential tremor cannot be cured. Treatment reduces the severity of the tremor, sometimes greatly. There are various treatments that are used but given only by your neurologyst doctor after making an physical examination. Many people find that alcohol is helpful in reducing their tremor. It needs to be used with caution to avoid developing an alcohol problem. It is not advisable to drink more than the normal recommended amount of alcohol. Men should drink no more than 21 units of alcohol per week, no more than four units in any one day, and have at least two alcohol-free days a week. Hope this information is helpful to you Best regards
