Tourette syndrome or Tourette's syndrome is a common neurodevelopmental disorder that begins in childhood or adolescence. It is characterized by multiple movement (motor) tics and at least one vocal (phonic) tic. Common tics are blinking, coughing, throat clearing, sniffing, and facial movements. These are typically preceded by an unwanted urge or sensation in the affected muscles known as a premonitory urge, can sometimes be suppressed temporarily, and characteristically change in location, strength, and frequency. Tourette's is at the more severe end of a spectrum of tic disorders. The tics often go unnoticed by casual observers.
A tic is a sudden and repetitive motor movement or vocalization that is not rhythmic and involves discrete muscle groups. It is typically brief, and may resemble a normal behavioral characteristic or gesture.
Excoriation disorder, more commonly known as dermatillomania, is a mental disorder on the obsessive–compulsive spectrum that is characterized by the repeated urge or impulse to pick at one's own skin, to the extent that either psychological or physical damage is caused.
Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) is a controversial hypothetical diagnosis for a subset of children with rapid onset of obsessive-compulsive disorder (OCD) or tic disorders. Symptoms are proposed to be caused by group A streptococcal (GAS), and more specifically, group A beta-hemolytic streptococcal (GABHS) infections. OCD and tic disorders are hypothesized to arise in a subset of children as a result of a post-streptococcal autoimmune process. The proposed link between infection and these disorders is that an autoimmune reaction to infection produces antibodies that interfere with basal ganglia function, causing symptom exacerbations, and this autoimmune response results in a broad range of neuropsychiatric symptoms.
Stereotypic movement disorder (SMD) is a motor disorder with onset in childhood involving restrictive and/or repetitive, nonfunctional motor behavior, that markedly interferes with normal activities or results in bodily injury. To be classified as SMD, the behavior in question must not be due to the direct effects of a substance, autism, or another medical condition. The cause of this disorder is not known.
Tourette syndrome is an inherited neurodevelopmental disorder that begins in childhood or adolescence, characterized by the presence of motor and phonic tics. The management of Tourette syndrome has the goal of managing symptoms to achieve optimum functioning, rather than eliminating symptoms; not all persons with Tourette's require treatment, and there is no cure or universally effective medication. Explanation and reassurance alone are often sufficient treatment; education is an important part of any treatment plan.
Causes and origins of Tourette syndrome have not been fully elucidated. Tourette syndrome is an inherited neurodevelopmental disorder that begins in childhood or adolescence, characterized by the presence of multiple motor tics and at least one phonic tic, which characteristically wax and wane. Tourette's syndrome occurs along a spectrum of tic disorders, which includes transient tics and chronic tics.
Sensory phenomena are general feelings, urges or bodily sensations. They are present in many conditions including autism spectrum disorders, epilepsy, neuropathy, obsessive–compulsive disorder, pain conditions, tardive syndromes, and tic disorders.
Habit reversal training (HRT) is a "multicomponent behavioral treatment package originally developed to address a wide variety of repetitive behavior disorders".
The Yale–Brown Obsessive–Compulsive Scale (Y-BOCS) is a test to rate the severity of obsessive–compulsive disorder (OCD) symptoms.
The obsessive–compulsive spectrum is a model of medical classification where various psychiatric, neurological and/or medical conditions are described as existing on a spectrum of conditions related to obsessive–compulsive disorder (OCD). "The disorders are thought to lie on a spectrum from impulsive to compulsive where impulsivity is said to persist due to deficits in the ability to inhibit repetitive behavior with known negative consequences, while compulsivity persists as a consequence of deficits in recognizing completion of tasks." OCD is a mental disorder characterized by obsessions and/or compulsions. An obsession is defined as "a recurring thought, image, or urge that the individual cannot control". Compulsion can be described as a "ritualistic behavior that the person feels compelled to perform". The model suggests that many conditions overlap with OCD in symptomatic profile, demographics, family history, neurobiology, comorbidity, clinical course and response to various pharmacotherapies. Conditions described as being on the spectrum are sometimes referred to as obsessive–compulsive spectrum disorders.

Obsessive–compulsive disorder (OCD) is a mental and behavioral disorder in which an individual has intrusive thoughts and feels the need to perform certain routines (compulsions) repeatedly to relieve the distress caused by the obsession, to the extent where it impairs general function.
Susan Swedo is a researcher in the field of pediatrics and neuropsychiatry. Beginning in 1998, she was Chief of the Pediatrics & Developmental Neuroscience Branch at the US National Institute of Mental Health. In 1994, Swedo was lead author on a paper describing pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), a controversial hypothesis proposing a link between Group A streptococcal infection in children and some rapid-onset cases of obsessive-compulsive disorder (OCD) or tic disorders such as Tourette syndrome. Swedo retired from the NIH in 2019, and serves on the PANDAS Physician Network.
The cause of obsessive–compulsive disorder is understood mainly through identifying biological risk factors that lead to obsessive–compulsive disorder (OCD) symptomology. The leading hypotheses propose the involvement of the orbitofrontal cortex, basal ganglia, and/or the limbic system, with discoveries being made in the fields of neuroanatomy, neurochemistry, neuroimmunology, neurogenetics, and neuroethology.
