Is repeating own last word or sound a complex vocal tic?

Repeating one's last word or sound, often referred to as palilalia, is a vocal tic, but not necessarily a complex one. Here's why:

* Simple vs. Complex Tics: Tics are involuntary, sudden movements or vocalizations. Simple tics are brief, isolated movements or vocalizations, while complex tics involve a sequence of movements or vocalizations.

* Palilalia: Repeating a word or sound is generally considered a simple vocal tic, as it involves a single, repetitive vocalization. It can occur alone or be part of a larger tic disorder.

* Complexity Varies: However, palilalia can sometimes be more complex. For example, repeating a phrase or sentence, or repeating a sound with increasing speed or volume, could be considered more complex.

Important Note: If you are experiencing any involuntary movements or vocalizations, it's crucial to consult a healthcare professional. They can assess your symptoms, diagnose any underlying conditions, and recommend appropriate treatment.
