Which statement is true regarding essential tremors?

Essential tremors are indeed characterized by slow tremors that typically involve the hands, particularly during voluntary movements such as reaching for an object or holding something steady. This type of tremor is different from resting tremors seen in conditions like Parkinson's disease, which are often more pronounced when the person is not actively using their hands.

In essential tremors, the involuntary movements generally increase with posture or intent to use the affected limbs. While they can be distressing and may impact daily activities, the nature of these tremors is distinct in their presentation as being more noticeable during specific actions rather than at rest. The correct categorization of essential tremors helps differentiate them from other neurological conditions, guiding appropriate management and treatment options for affected individuals.
