Summary
Oromandibular (OM) tics are common in Tourette syndrome (TS), often causing severe symptoms. Differentiating OM tics from tardive dyskinesia (TD) is key, as TD typically involves continuous movements.
Area of Science:
- Neurology
- Movement Disorders
Background:
- Tourette syndrome (TS) is a common cause of chronic tics, frequently affecting the eyes and face.
- Oromandibular (OM) tics in TS have been understudied despite their potential severity.
Approach:
- Reviewed medical records and video-recordings of 155 TS patients.
- Compared 41 TS patients with OM tics to 35 patients with classic tardive dyskinesia (TD).
Key Points:
- OM tics were identified in 26.5% of TS patients.
- Patients with OM tics showed greater overall tic severity and complex motor/phonic tics.
- Comorbid dystonic tics and more affected body parts were associated with OM tics.
Conclusions:
- OM tics are a frequent and potentially disabling symptom in TS.
- Distinguishing OM tics from TD is important; TD often presents with continuous orolingual and masticatory movements.

180
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

01:30Oppositional Defiant Disorder
111
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

197
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...

01:15REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

01:22Cranial Nerves: Types Part II
2.6K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

01:24Parkinson's Disease: Treatment
330
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
