Which of the following is an example of neurogenic voice disorder?

An example of a neurogenic voice disorder is essential tremor, which involves involuntary muscle contractions that lead to rhythmic shaking. This condition can affect the muscles involved in voice production, causing variations in pitch and loudness that disrupt the normal vocal pattern. Neurogenic voice disorders arise from problems in the nervous system that affect the control of voice production. Essential tremor specifically relates to the neurological aspect, as it originates from issues in the brain that impact motor function.

In contrast, laryngitis is an inflammation of the larynx often caused by infection or overuse, while vocal fold nodules are benign growths resulting from vocal abuse or misuse. Functional dysphonia, on the other hand, is characterized by a voice disorder without identifiable physical or neurological causes and is typically associated with psychological or behavioral factors. These conditions do not stem from neurological dysfunction, making essential tremor the appropriate choice for this question.
