Impact of co-morbid attention-deficit and hyperactivity disorder on cognitive function in male children with Tourette syndrome: A controlled study.

Tourette syndrome (TS) and attention-deficit and hyperactivity disorder (ADHD) are co-morbid neurodevelopmental conditions affecting more commonly male patients. We set out to determine the impact of co-morbid ADHD on cognitive function in male children with TS by conducting a controlled study. Participants included four matched groups of unmedicated children (age range 6-15 years): TS (n=13), TS+ADHD (n=8), ADHD (n=39), healthy controls (n=66).

The effects of Gilles de la Tourette syndrome and other chronic tic disorders on quality of life across the lifespan: a systematic review.

Gilles de la Tourette syndrome (GTS) and other chronic tic disorders are neurodevelopmental conditions characterized by the presence of tics and associated behavioral problems. Whilst converging evidence indicates that these conditions can affect patients' quality of life (QoL), the extent of this impairment across the lifespan is not well understood. We conducted a systematic literature review of published QoL studies in GTS and other chronic tic disorders to comprehensively assess the effects of these conditions on QoL in different age groups.

Personality Profile of Male Adolescents With Tourette Syndrome: A Controlled Study.

Tourette syndrome is a neurodevelopmental disorder characterized by multiple tics and commonly associated with behavioral problems, especially obsessive-compulsive disorder and attention-deficit hyperactivity disorder (ADHD). The presence of specific personality traits has been documented in adult clinical populations with Tourette syndrome but has been underresearched in younger patients. We assessed the personality profiles of 17 male adolescents with Tourette syndrome and 51 age- and gender-matched healthy controls using the Minnesota Multiphasic Personality Inventory-Adolescent version, along with a standardized psychometric battery.

Antiepileptic drugs and Tourette syndrome.

Tourette syndrome is a neurodevelopmental disorder characterized by the chronic presence of multiple motor tics and at least one vocal/phonic tic for the duration of 1 year. The clinical picture of patients with Tourette syndrome is often complicated by tic-related behavioral problems and associated psychopathology. The pathophysiology of Tourette syndrome is not thoroughly understood, however converging evidence from neuroimaging studies suggests abnormalities within the frontostriatal pathways which are mediated by several neurotransmitters.

Tourette syndrome and consciousness of action.

Background: Tourette syndrome (TS) is a neuropsychiatric disorder characterized by the chronic presence of multiple motor tics and at least one vocal/phonic tic since childhood. Tics typically change and vary in both intensity and severity over time, with remission and exacerbation common. In the vast majority of patients, tic expression is characteristically accompanied by discomforting bodily sensations, known as sensory phenomena or premonitory urges.

Parkinsonian features in a case of pellagra: a historical report.

Pellagra is a complex systemic disease resulting from inadequate dietary intake of coenzyme precursors nicotinamide and tryptophan. Improved nutritional habits in most developed economies have led to a decrease in clinicians' and researchers' attention to this condition and its pathophysiological bases, although new cases of pellagra have recently been identified in association with alcohol abuse and HIV infection in Western countries. Pellagra is characterized by a complex clinical picture, which can include neuropsychiatric symptoms and Parkinsonian features.
