Older individuals are more likely to develop symptoms of essential tremor. Despite this, essential tremor is not a part of the natural aging process. The first symptoms of essential tremor do not manifest in most patients until the fourth or fifth decade of their life. Around four percent of individuals who are forty years old or older are affected by some tremors. The mean age of affected individuals at the time of their first symptoms is between thirty-five and forty-five years old.
Most individuals who will develop essential tremor will see symptoms by sixty-five years old and most definitely by seventy years old. There is a negative correlation between the severity and frequency of essential tremor as it progresses over time. The severity of essential tremor tends to worsen as patients age. In contrast, the frequency of their tremor episodes tends to decrease as they age. It is rare for essential tremor to be seen in children, newborns, and infants.
