Prevalence of Diagnosed Tourette Syndrome in Persons Aged 6--17 Years --- United States, 2007 (MMWR 2009)

The course of panic attacks in individuals with panic disorder and subthreshold panic disorder: A population-based study. (J Affect Disord. 2009) “RESULTS: Thirty-nine percent of those with panic disorder and 17% of those with subthreshold panic disorder reported panic episodes during more than 75% of the observed time periods in the Life Chart Interview. Forty-three percent of those with panic disorder and 14% of those with subthreshold panic disorder reported over 24 attacks per 3-month period. Male gender, severity of panic and agoraphobia predicted a high proportion of time spent in panic episodes. Low self-esteem, limited positive life events and severity of panic predicted highly frequent attacks.”

Three in Every One Thousand U.S. Children Diagnosed with Tourette Syndrome “The study, “Prevalence of Diagnosed Tourette Syndrome in Children in the United States, 2007,” found that a TS diagnosis is three times more common in boys than in girls, and approximately twice as common in children between 12-17 years as those aged 6-12 years. Among children with TS, 27% were reported as having moderate or severe TS and 79% of children had also been diagnosed with at least one additional mental health or neurodevelopmental condition. Tourette Syndrome is a neurological disorder that typically begins during early childhood, with symptoms being most severe between the ages of 10 and 12 years. TS is characterized by recurring multiple motor tics and at least one vocal tic. Tics are involuntary, repetitive, stereotyped, usually sudden and rapid movements or vocalizations that may be suppressed for short periods of time. “TS and tic disorders have been linked to higher rates of Attention Deficit/Hyperactivity Disorder, obsessive-compulsive disorder, and impairments associated with these conditions, such as learning disabilities and problems with peer relations,” said Dr. Rebecca Bitsko, Health Scientist at the Centers for Disease Control and Prevention. “Given the high number of children diagnosed with TS who have another mental health or neurodevelopmental condition, it is necessary to further study the relation between these conditions.” “
