A premonitory urge is a sensory phenomenon associated with Tourette syndrome and other tic disorders. Premonitory urges are "uncomfortable feelings or sensations preceding tics that usually are relieved by [a particular] movement". [1]
"Individuals with tics may have either a generalized or a localized sensation of tension that is relieved by movement, [that is] the tic." [2] Sensory phenomena in tic disorders include bodily sensations, mental urges, and a sense of inner tension, feelings of incompleteness, and a need for things to be "just right". Bodily sensations include focal or generalized body sensations (usually tactile, muscular-skeletal/visceral, or both); mental sensations include urge only, energy release (mental energy that builds up and needs to be discharged), incompleteness, and just-right perceptions. [3] Published descriptions of the tics of Tourette's identify sensory phenomena as the core symptom of Tourette syndrome, even though they are not included in the diagnostic criteria. [4] [3]
In contrast to the stereotyped movements of other movement disorders such as choreas, dystonias, myoclonus, and dyskinesias, the tics of Tourette's are temporarily suppressible and preceded by this premonitory urge. [5] Immediately preceding tic onset, most individuals with Tourette syndrome are aware of an urge, [6] which is similar to the need to sneeze or scratch an itch. Individuals describe the need to tic as the buildup of tension in a particular anatomical location, [7] which they consciously choose to release, as if the subject "had to do it". [8] Examples of the premonitory urge are the feeling of having something in one's throat, or a localized discomfort in the shoulders, leading to the need to clear one's throat or shrug the shoulders. The actual tic may be felt as relieving this tension or sensation, similar to scratching an itch. Another example is blinking to relieve an uncomfortable sensation in the eye. [4]
The presence of sensory phenomena differentiates subjects with Tourette syndrome plus obsessive–compulsive disorder (OCD) from subjects with OCD alone, [9] and may be an important measure for grouping patients along the OCD-Tourette's disorder spectrum. [3]
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.
Coprolalia is involuntary swearing or the involuntary utterance of obscene words or socially inappropriate and derogatory remarks. The word comes from the Greek κόπρος, meaning "dung, feces", and λαλιά "speech", from λαλεῖν "to talk".
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.
Sensory overload occurs when one or more of the body's senses experiences over-stimulation from the environment.
Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS) is a 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.
Tic disorders are defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM) based on type and duration of tics. Tic disorders are defined similarly by the World Health Organization.
An intrusive thought is an unwelcome, involuntary thought, image, or unpleasant idea that may become an obsession, is upsetting or distressing, and can feel difficult to manage or eliminate. When such thoughts are associated with obsessive–compulsive disorder (OCD), Tourette syndrome (TS), depression, body dysmorphic disorder (BDD), and sometimes attention deficit hyperactivity disorder (ADHD), the thoughts may become paralyzing, anxiety-provoking, or persistent. Intrusive thoughts may also be associated with episodic memory, unwanted worries or memories from OCD, post-traumatic stress disorder (PTSD), other anxiety disorders, eating disorders, or psychosis. Intrusive thoughts, urges, and images are of inappropriate things at inappropriate times, and generally have aggressive, sexual, or blasphemous themes.
Societal and cultural aspects of Tourette syndrome include legal advocacy and health insurance issues, awareness of notable individuals with Tourette syndrome, and treatment of TS in the media and popular culture.
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.
Arthur K. Shapiro, M.D., was an American psychiatrist and expert on Tourette syndrome. His "contributions to the understanding of Tourette syndrome completely changed the prevailing view of this disorder"; he has been described as "the father of modern tic disorder research" and is "revered by his colleagues as the first dean of modern Tourette syndrome researchers".
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 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.
Tourette syndrome (TS) is an inherited neurological disorder that begins in childhood or adolescence, characterized by the presence of multiple physical (motor) tics and at least one vocal (phonic) tic.
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.
