Disorders characterized by recurrent TICS that may interfere with speech and other activities. Tics are sudden, rapid, nonrhythmic, stereotyped motor movements or vocalizations which may be exacerbated by stress and are generally attenuated during absorbing activities. Tic disorders are distinguished from conditions which feature other types of abnormal movements that may accompany another another condition. (From DSM-IV, 1994)
Habitual, repeated, rapid contraction of certain muscles, resulting in stereotyped individualized actions that can be voluntarily suppressed for only brief periods. They often involve the face, vocal cords, neck, and less often the extremities. Examples include repetitive throat clearing, vocalizations, sniffing, pursing the lips, and excessive blinking. Tics tend to be aggravated by emotional stress. When frequent they may interfere with speech and INTERPERSONAL RELATIONS. Conditions which feature frequent and prominent tics as a primary manifestation of disease are referred to as TIC DISORDERS. (From Adams et al., Principles of Neurology, 6th ed, pp109-10)
A neuropsychological disorder related to alterations in DOPAMINE metabolism and neurotransmission involving frontal-subcortical neuronal circuits. Both multiple motor and one or more vocal tics need to be present with TICS occurring many times a day, nearly daily, over a period of more than one year. The onset is before age 18 and the disturbance is not due to direct physiological effects of a substance or a another medical condition. The disturbance causes marked distress or significant impairment in social, occupational, or other important areas of functioning. (From DSM-IV, 1994; Neurol Clin 1997 May;15(2):357-79)
An anxiety disorder characterized by recurrent, persistent obsessions or compulsions. Obsessions are the intrusive ideas, thoughts, or images that are experienced as senseless or repugnant. Compulsions are repetitive and seemingly purposeful behavior which the individual generally recognizes as senseless and from which the individual does not derive pleasure although it may provide a release from tension.
Persistent, unwanted idea or impulse which is considered normal when it does not markedly interfere with mental processes or emotional adjustment.
A behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood. (From DSM-V)
Assessment of sensory and motor responses and reflexes that is used to determine impairment of the nervous system.

Recognition and management of Tourette's syndrome and tic disorders. (1/76)

Tic disorders and Tourette's syndrome are conditions that primary care physicians are likely to encounter. Up to 20 percent of children have at least a transient tic disorder at some point. Once believed to be rare, Tourette's syndrome is now known to be a more common disorder that represents the most complex and severe manifestation of the spectrum of tic disorders. Tourette's syndrome is a chronic familial disorder with a fluctuating course; the long-term outcome is generally favorable. Although the exact underlying pathology has yet to be determined, evidence indicates a disorder localized to the frontal-subcortical neural pathways. Tourette's syndrome is commonly associated with attention-deficit/hyperactivity disorder, obsessive-compulsive disorder, behavior problems and learning disabilities. These comorbid conditions make the management of Tourette's syndrome more challenging. Management of Tourette's syndrome should include timely and accurate diagnosis, education, and behavior or pharmacologic interventions. Use of neuroleptic medications and dopamine D2 antagonist drugs can be effective but may be associated with significant side effects.  (+info)

Parent perceptions of symptom severity in Tourette's syndrome. (2/76)

The families of 66 consecutive children with Tourette's syndrome were surveyed for their perception of symptom significance using a questionnaire. Families considered attention deficit and learning difficulties to be most significant, while motor and vocal tics were least important. When present, episodic rage was the most impairing symptom. Physicians must be aware of the significance of these comorbid symptoms for patients with Tourette's syndrome.  (+info)

Adult onset tic disorders. (3/76)

BACKGROUND: Tic disorders presenting during adulthood have infrequently been described in the medical literature. Most reports depict adult onset secondary tic disorders caused by trauma, encephalitis, and other acquired conditions. Only rare reports describe idiopathic adult onset tic disorders, and most of these cases represent recurrent childhood tic disorders. OBJECTIVE: To describe a large series of patients with tic disorders presenting during adulthood, to compare clinical characteristics between groups of patients, and to call attention to this potentially disabling and underrecognised neurological disorder. METHODS: Using a computerised database, all patients with tic disorders who presented between 1988 and 1998 to the movement disorders clinic at Columbia-Presbyterian Medical Center after the age of 21 were identified. Patients' charts were retrospectively reviewed for demographic information, age of onset of tics, tic phenomenology, distribution, the presence of premonitory sensory symptoms and tic suppressibility, family history, and associated psychiatric features. These patients' videotapes were reviewed for diagnostic confirmation and information was obtained about disability, course, and response to treatment in a structured follow up interview. RESULTS: Of 411 patients with tic disorders in the database, 22 patients presented for the first time with tic disorders after the age of 21. In nine patients, detailed questioning disclosed a history of previous childhood transient tic disorder, but in 13 patients, the adult onset tic disorder was new. Among the new onset cases, six patients developed tics in relation to an external trigger, and could be considered to have secondary tic disorders. The remaining patients had idiopathic tic disorders. Comparing adult patients with recurrent childhood tics and those with new onset adult tics, the appearance of the tic disorder, the course and prognosis, the family history of tic disorder, and the prevalence of obsessive-compulsive disorder were found to be similar. Adults with new onset tics were more likely to have a symptomatic or secondary tic disorder, which in this series was caused by infection, trauma, cocaine use, and neuroleptic exposure. CONCLUSIONS: Adult onset tic disorders represent an underrecognised condition that is more common than generally appreciated or reported. The clinical characteristics of adults newly presenting to a movement disorder clinic with tic disorders are reviewed, analysed, and discussed in detail. Clinical evidence supports the concept that tic disorders in adults are part of a range that includes childhood onset tic disorders and Tourette's syndrome.  (+info)

Significant linkage for Tourette syndrome in a large French Canadian family. (4/76)

Family and twin studies provide strong evidence that genetic factors are involved in the transmission of Gilles de la Tourette syndrome (TS) and related psychiatric disorders. To detect the underlying susceptibility gene(s) for TS, we performed linkage analysis in one large French Canadian family (127 members) from the Charlevoix region, in which 20 family members were definitely affected by TS and 20 others showed related tic disorders. Using model-based linkage analysis, we observed a LOD score of 3.24 on chromosome 11 (11q23). This result was obtained in a multipoint approach involving marker D11S1377, the marker for which significant linkage disequilibrium with TS recently has been detected in an Afrikaner population. Altogether, 25 markers were studied, and, for level of significance, we derived a criterion that took into account the multiple testing arising from the use of three phenotype definitions and three modes of inheritance, a procedure that yielded a LOD score of 3.18. Hence, even after adjustment for multiple testing, the present study shows statistically significant evidence for genetic linkage with TS.  (+info)

Bereitschaftspotential in tic disorders: a preliminary observation. (5/76)

Sensory phenomena in tic disorders such as Tourette's syndrome are known but are substantiated by only a handful of studies. In this preliminary report, we studied premonitory urge, a type of sensory phenomenon in three patients of tic disorders. Bereitschaftspotential, a movement-related cognitive potential indicative of motor preparation, was assessed in these patients. As bereitschaftspotential was observed in all our cases prior to occurrence of tics, it is speculated that tics are not entirely involuntary but are quasi-volitional in nature. Bereitschaftspotential may thus represent a neurophysiological marker of premonitory urge in tic disorders. Implications of exploring the voluntary nature of tics are discussed.  (+info)

Prevalence of tic disorders among primary school students in the city of Pavia, Italy. (6/76)

BACKGROUND: The prevalence of tic disorders in children varies from 1% to 29% depending on the characteristics of the study population, the diagnostic criteria, and the study design and methods. AIMS: To calculate the prevalence of tic disorders among primary school children in Italy. METHODS: The study population comprised 2347 primary school children from the city of Pavia (pop. 80 073), Northern Italy. Using trained school teachers as the source of cases, all children with motor or vocal tics occurring intermittently and unpredictably out of a background of normal motor activity were accepted. The type, frequency, and circumstances of tic disorders were noted. School performance was correlated to the presence of tics. RESULTS: A total of 68 children (56 boys, 12 girls) aged 6-11 years were identified with tic disorders. The period prevalence was 2.9% (95% CI 2.3 to 3.7). The prevalence was 4.4% in boys and 1.1% in girls, with no detectable trends at age 6-11. Motor tics were present in 46 cases, vocal tics in 6, and motor and vocal tics in 16. Situation related tics were noted in 37 cases. A significant correlation was found between the presence of tic disorders and impaired school performance. DISCUSSIONS: Tic disorders are a fairly uncommon but disabling clinical disorder among primary school children from an urban community. The fairly low prevalence of this clinical condition, as compared to other reports, can be explained by the choice of stringent diagnostic criteria and the exclusion of patients with other movement disorders.  (+info)

Eye movement tics. (7/76)

An 8-year-old girl presented with opsoclonus-like eye movement and an 18 month history of intermittent facial tics. Investigations were all normal. Electro-oculography showed the eye movements to be of variable amplitude (10-40 degrees), with no intersaccadic interval, and with a frequency of 3-4 Hz. Saccades, smooth pursuit, optokinetic, and vestibular reflexes were all normal. These abnormal eye movements eventually disappeared. It is thought that they were a form of ocular tics.  (+info)

Anti-basal ganglia antibodies: a possible diagnostic utility in idiopathic movement disorders? (8/76)

BACKGROUND: The spectrum of post-streptococcal brain disorders includes chorea, tics, and dystonia. The proposed mediators of disease are anti-basal ganglia (neuronal) antibodies (ABGA). AIM: To evaluate ABGA as a potential diagnostic marker in a cohort of UK post-streptococcal movement disorders. METHODS: Forty UK children presenting with movement disorders associated with streptococcal infection were recruited. ABGA was measured using ELISA and Western immunoblotting. To determine ABGA specificity and sensitivity, children with neurological diseases (n = 100), children with uncomplicated streptococcal infection (n = 40), and children with autoimmune disease (n = 50) were enrolled as controls. RESULTS: The mean ELISA result was increased in the post-streptococcal movement disorder group compared to all controls and derived a sensitivity of 82.4% and specificity of 79%. The Western immunoblotting method to detect ABGA derived a sensitivity and specificity of 92.5% and 94.7% respectively. There was common binding to basal ganglia antigens of 40, 45, and 60 kDa. Immunofluorescence localised the antibody binding to basal ganglia neurones. CONCLUSION: ABGA appears to be a potentially useful diagnostic marker in post-streptococcal neurological disorders. Western immunoblotting appears to be the preferred method due to good sensitivity and specificity and the ability to test several samples at once.  (+info)

Tic disorders are a group of conditions characterized by the presence of repetitive, involuntary movements or sounds, known as tics. These movements or sounds can vary in complexity and severity, and they may be worsened by stress or strong emotions.

There are several different types of tic disorders, including:

1. Tourette's disorder: This is a neurological condition characterized by the presence of both motor (movement-related) and vocal tics that have been present for at least one year. The tics may wax and wane in severity over time, but they do not disappear for more than three consecutive months.
2. Persistent (chronic) motor or vocal tic disorder: This type of tic disorder is characterized by the presence of either motor or vocal tics (but not both), which have been present for at least one year. The tics may wax and wane in severity over time, but they do not disappear for more than three consecutive months.
3. Provisional tic disorder: This type of tic disorder is characterized by the presence of motor or vocal tics (or both) that have been present for less than one year. The tics may wax and wane in severity over time, but they do not disappear for more than three consecutive months.
4. Tic disorder not otherwise specified: This category is used to describe tic disorders that do not meet the criteria for any of the other types of tic disorders.

Tic disorders are thought to be caused by a combination of genetic and environmental factors, and they often co-occur with other conditions such as attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). Treatment for tic disorders may include behavioral therapy, medication, or a combination of both.

A tic is a sudden, repetitive, involuntary movement or vocalization that occurs frequently. Tics can be simple, involving only one muscle group, or complex, involving several muscle groups or coordinated patterns of movements. Common motor tics include eye blinking, facial grimacing, and shoulder shrugging, while common vocal tics include throat clearing, sniffing, and grunting.

Tics can vary in severity and frequency over time, and they may be exacerbated by stress, anxiety, or fatigue. In some cases, tics may be suppressible for brief periods of time, but this can lead to a buildup of tension that eventually results in an explosive release of the tic.

Tourette syndrome is a neurological disorder characterized by the presence of both motor and vocal tics that persist for more than one year. However, tics can also occur as a symptom of other medical conditions, such as Huntington's disease, Wilson's disease, or certain infections. In some cases, tics may be caused by medication side effects or substance abuse.

Tourette Syndrome (TS) is a neurological disorder characterized by the presence of multiple motor tics and at least one vocal (phonic) tic. These tics are sudden, repetitive, rapid, involuntary movements or sounds that occur for more than a year and are not due to substance use or other medical conditions. The symptoms typically start before the age of 18, with the average onset around 6-7 years old.

The severity, frequency, and types of tics can vary greatly among individuals with TS and may change over time. Common motor tics include eye blinking, facial grimacing, shoulder shrugging, and head or limb jerking. Vocal tics can range from simple sounds like throat clearing, coughing, or barking to more complex phrases or words.

In some cases, TS may be accompanied by co-occurring conditions such as attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, and depression. These associated symptoms can sometimes have a greater impact on daily functioning than the tics themselves.

The exact cause of Tourette Syndrome remains unclear, but it is believed to involve genetic factors and abnormalities in certain brain regions involved in movement control and inhibition. There is currently no cure for TS, but various treatments, including behavioral therapy and medications, can help manage the symptoms and improve quality of life.

Obsessive-Compulsive Disorder (OCD) is a mental health disorder characterized by the presence of obsessions and compulsions. Obsessions are recurrent and persistent thoughts, urges, or images that are intrusive, unwanted, and often distressing. Compulsions are repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession or according to rigid rules, and which are aimed at preventing or reducing anxiety or distress, or preventing some dreaded event or situation. These obsessions and/or compulsions cause significant distress, take up a lot of time (an hour or more a day), and interfere with the individual's daily life, including social activities, relationships, and work or school performance. OCD is considered a type of anxiety disorder and can also co-occur with other mental health conditions.

Obsessive behavior is defined in the medical context as repetitive, persistent, and intrusive thoughts, images, or urges that cause distress or anxiety. These obsessions are not simply excessive worries about real-life problems, but rather they are irrational and uncontrollable. Often, individuals with obsessive behavior attempt to ignore or suppress their obsessions, which can lead to increased distress and anxiety. In some cases, the obsessions may become so overwhelming that they interfere with a person's daily life and ability to function.

Obsessive behavior is a key feature of several mental health conditions, including obsessive-compulsive disorder (OCD), body dysmorphic disorder (BDD), and hoarding disorder. In these conditions, the obsessions are often accompanied by compulsive behaviors that are performed in an attempt to alleviate the anxiety or distress caused by the obsessions.

It is important to note that everyone experiences unwanted thoughts or urges from time to time. However, when these thoughts become so frequent and distressing that they interfere with a person's daily life, it may be indicative of an underlying mental health condition. In such cases, it is recommended to seek professional help from a qualified mental health provider.

Attention Deficit Hyperactivity Disorder (ADHD) with hyperactivity is a neurodevelopmental disorder that affects both children and adults. The condition is characterized by symptoms including:

1. Difficulty paying attention or staying focused on a single task
2. Impulsivity, or acting without thinking
3. Hyperactivity, or excessive fidgeting, restlessness, or talking

In order to be diagnosed with ADHD with hyperactivity, an individual must exhibit these symptoms to a degree that is developmentally inappropriate and interferes with their daily functioning. Additionally, the symptoms must have been present for at least six months and be present in multiple settings (e.g., at home, school, work).

It's important to note that ADHD can manifest differently in different people, and some individuals may experience predominantly inattentive or impulsive symptoms rather than hyperactive ones. However, when the hyperactive component is prominent, it is referred to as ADHD with hyperactivity.

Effective treatments for ADHD with hyperactivity include a combination of medication (such as stimulants) and behavioral therapy. With appropriate treatment, individuals with ADHD can learn to manage their symptoms and lead successful, fulfilling lives.

A neurological examination is a series of tests used to evaluate the functioning of the nervous system, including both the central nervous system (the brain and spinal cord) and peripheral nervous system (the nerves that extend from the brain and spinal cord to the rest of the body). It is typically performed by a healthcare professional such as a neurologist or a primary care physician with specialized training in neurology.

During a neurological examination, the healthcare provider will assess various aspects of neurological function, including:

1. Mental status: This involves evaluating a person's level of consciousness, orientation, memory, and cognitive abilities.
2. Cranial nerves: There are 12 cranial nerves that control functions such as vision, hearing, smell, taste, and movement of the face and neck. The healthcare provider will test each of these nerves to ensure they are functioning properly.
3. Motor function: This involves assessing muscle strength, tone, coordination, and reflexes. The healthcare provider may ask the person to perform certain movements or tasks to evaluate these functions.
4. Sensory function: The healthcare provider will test a person's ability to feel different types of sensations, such as touch, pain, temperature, vibration, and proprioception (the sense of where your body is in space).
5. Coordination and balance: The healthcare provider may assess a person's ability to perform coordinated movements, such as touching their finger to their nose or walking heel-to-toe.
6. Reflexes: The healthcare provider will test various reflexes throughout the body using a reflex hammer.

The results of a neurological examination can help healthcare providers diagnose and monitor conditions that affect the nervous system, such as stroke, multiple sclerosis, Parkinson's disease, or peripheral neuropathy.
