Final answer:
Tourette's syndrome is often associated with Obsessive-compulsive disorder (OCD). This link is due to shared characteristics such as repetitive behaviors and potential genetic factors. Techniques like relaxation and exercise can help manage symptoms of both conditions.
Step-by-step explanation:
Tourette's syndrome often involves psychiatric manifestations, and among the options provided, Tourette's syndrome is most commonly associated with Obsessive-compulsive disorder (OCD). This neurological disorder is characterized by involuntary vocal sounds and movements. Relaxation techniques and exercise may help to reduce symptoms. However, it's important to note that anxiety disorders are the most common mental disorders in the United States, with a significant portion of the adult population likely to be affected at some point in their lifetimes.
Individuals with Tourette's may display impaired social skills and exhibit repetitive behaviors, which can be similar to those seen in OCD. Studies, such as those by Bolton et al. (2007) and Abramowitz & Siqueland (2013), support the evidence of a linkage between Tourette's syndrome and OCD. Moreover, these disorders have a genetic component, adding to the complexity of their relationship. Therefore, among the psychiatric manifestations listed, OCD is the one most often involved with Tourette's.
