Self-injurious behavior, self-restraint, and compulsive behaviors in Cornelia de Lange syndrome.

Researchers have argued that individuals who show self-restraint are more likely to show self-injurious behavior (SIB) that is compulsive. Self-injurious behavior, self-restraint, and compulsive behaviors have been described as features of Cornelia de Lange syndrome. We examined whether individuals with this syndrome displaying SIB and self-restraint exhibit more compulsive behaviors than do those without SIB and self-restraint. Main caregivers of individuals with the syndrome completed questionnaires. A significant association was found between SIB and self-restraint, and those displaying both behaviors displayed significantly more compulsions than did those not exhibiting them. Findings extend the compulsive behavior theory and highlight areas for further research.

The role of cognitive and affective processing in a transgenic mouse model of cortical-limbic neuropotentiated compulsive behavior.

Obsessive compulsive disorder (OCD) may involve abnormal cortical-limbic processing or responsiveness. Mice with behaviors resembling the symptoms of OCD and related disorders were made by expression of a neuropotentiating cholera toxin (CT) transgene in cortical-limbic D1 receptor-expressing neurons. Because these D1CT mice express CT in the piriform cortex and amygdala (major cognitive and affective olfactory processing areas) it was tested whether abnormal odor perception, discrimination, or responsiveness facilitates their compulsion-like behavior. The mice exhibited normal olfactory discriminative capability. An anxiogenic odor potentiated their abnormal repetitive leaping, but novel or familiar nonthreatening odors did not. These data suggest that compulsions can be triggered not by impaired cortical-limbic processing but by increased cortical-limbic responsiveness, particularly to sensory or cognitive stimuli with affective properties.

Substance dependence as a compulsive behavior.

A compulsion to take a drug combined with a loss of control in limiting intake is the defining feature of substance dependence or addiction, and is the conceptual framework for the criteria of substance dependence or addiction outlined by the World Health Organization and the American Psychiatric Association. However, defining exactly what constitutes loss of control and compulsive drug taking at the level of animal models is a daunting task, and it is clear that no validated animal model exists for the whole syndrome of addiction. The present discussion redefines loss of control as a narrowing of the behavioral repertoire toward drug-seeking behavior and suggests that there are many sources of reinforcement that contribute to this behavioral focus on drug seeking. Evidence is presented demonstrating separate animal models for many of these sources of reinforcement as well as for most of the criteria for substance dependence. Evidence is also presented showing that the brain neurochemical systems involved in processing drug reward are altered by chronic drug exposure to contribute additional sources of reinforcement. Challenges for the future involve not only elucidation of the neurobiological substrates of the different behavioral components of addiction, but better animal models of these components with which to effect such studies.

"Just right" perceptions associated with compulsive behavior in Tourette's syndrome.

OBJECTIVE: Tourette's syndrome is a chronic disorder of childhood onset that is characterized by motor and phonic tics and a broad range of associated behavior including obsessive-compulsive symptoms. Less well appreciated are the sensory and other perceptually tinged mental phenomena associated with both tic and compulsive behavior. This cross-sectional study evaluated the "just-right" phenomena commonly associated with compulsive behavior in subjects with tic disorders. METHOD: A total of 134 subjects with tic disorders, aged 9 to 71 years, completed a questionnaire concerning their current and past tic symptoms. Subjects were also asked to describe their "just right" perceptions. The Yale-Brown Obsessive Compulsive Scale was used to assess severity of current obsessive-compulsive symptoms. RESULTS: Eight-one percent of the subjects with both Tourette's syndrome and obsessive-compulsive disorder (N = 31) and 56% of the subjects with Tourette's syndrome and obsessive-compulsive symptoms (N = 61) reported being aware of a need to perform compulsions until they were "just right." This awareness most commonly referred to visual or tactile (as opposed to auditory) features of the compulsive act or its consequences. Three-quarters of the subjects with these perceptions reported that they usually were aware of them immediately before or concurrently with the initiation of compulsions. CONCLUSIONS: While epidemiological studies of tic disorders and obsessive-compulsive disorder have yet to incorporate questions concerning "just right" perceptions, these results suggest that such perceptions may be commonplace in adolescent and adult subjects with both obsessive-compulsive disorder and tic disorders. They also implicate brain regions involved in the processing of sensorimotor information in the pathobiology of tic disorders.

Compulsive behaviors and obsessive-compulsive disorder (OCD): lack of a relationship between OCD, eating disorders, and gambling.

The lifetime prevalence of eating disorders and pathologic gambling was assessed in first-degree relatives of subjects with obsessive-compulsive disorder (OCD) and well controls. There were no significant differences between the groups. The authors conclude that eating disorder and pathologic gambling have no familial relationship to OCD.

An examination of the phenomenology and the reliability of ratings of compulsive behavior in autism.

To clarify the nature of compulsive behavior in autism, staff reports of behavioral patterns of 17 young autistic adults living in a farmstead residential facility were analyzed. Three staff members, who had worked most closely with each resident for at least 3 months completed three questionnaires, including Quantitative and Qualitative compulsive behavior scales, and the Childhood Autism Rating Scale (CARS). The questionnaires were completed on two occasions with a 2-week interval between administrations. Test-retest and interrater consistencies were examined for each of the scales. Both the Qualitative and Quantitative questionnaires show promise as instruments that could be used as objective baselines or descriptors for compulsive behavior in autism. Information gathered from these scales could be utilized to determine how to intervene in the behavior, and to assess progress in treatment programs.

Compulsive behavior in tobacco users.

Addictions have been associated with compulsive behaviors, which serve to reduce emotional distress. Tobacco use has been associated with increased adverse moods such as anxiety. Nicotine has established anxiolytic effects through modulation of central neurotransmitters, including monoamines. Both obsessive-compulsive behaviors and tobacco use have both been associated with dysfunction in orbitofrontal-subcortical circuits. This study demonstrated greater intensity of compulsive behaviors (as measured by the Yale-Brown Obsessive Compulsive Scale [Y-BOCS]) in tobacco users compared to nonusers, which was not due to demographic influences or use of other psychoactive drugs. Both the frequency of tobacco use and level of overall emotional distress correlated positively with the severity of compulsive symptoms. The results are consistent with tobacco use as a form of self-medicating compulsive symptoms, likely through monoamine modulation of orbitofrontal-subcortical circuits.

Compulsive behaviors as presenting symptoms of frontotemporal dementia.

Frontotemporal dementia (FTD) is a common neurodegenerative dementia syndrome. Compulsive behaviors frequently occur in FTD and may be presenting symptoms of this disorder. This study evaluated compulsive behaviors as presenting symptoms in 29 patients with FTD compared to 48 patients with Alzheimer's disease (AD) enrolled in the UCLA Alzheimer's Disease Center. The FTD patients met the Lund and Manchester criteria for FTD and had predominant frontal hypoperfusion on single-photon emission computer tomography neuroimaging. The AD patients met National Institute of Neurological and Communicative Disorders-Alzheimer's Disease and Related Disorders criteria for clinically probable AD. Compulsive behaviors occurred in 11 FTD patients (38%) versus 5 AD patients (10%) (chi2 = 6.73, P < .01). This difference persisted after controlling for the younger age of the FTD group. There was a range of compulsive behaviors, with the most frequent being repetitive checking activities. Compulsive behaviors are common presenting symptoms among FTD patients and may result from an inability to inhibit urges to perform compulsive movements from damage to frontal-striatal circuits.

Treatment of crack-cocaine-induced compulsive behavior with trazodone.

Foraging is a compulsive behavior of searching for pieces of crack cocaine that the individual believes might have been accidentally misplaced. Three clinical cases of compulsive foraging behavior associated with crack cocaine are described. Due to the development of side effects secondary to the antidepressant desipramine, the patients were switched to the antidepressant trazodone. The use of trazodone led to remission of the foraging behavior. The authors hypothesize this remission was due to trazodone serotonin reuptake inhibitory action. In all three cases, the patients did not relapse into abusing crack cocaine.

Estrogen deficient male mice develop compulsive behavior.

BACKGROUND: Aromatase converts androgen to estrogen. Thus, the aromatase knockout (ArKO) mouse is estrogen deficient. We investigated the compulsive behaviors of these animals and the protein levels of catechol-O-methyltransferase (COMT) in frontal cortex, hypothalamus and liver. METHODS: Grooming was analyzed during the 20-min period immediately following a water-mist spray. Running wheel activity over two consecutive nights and barbering were analyzed. COMT protein levels were measured by Western analysis. RESULTS: Six-month old male but not female ArKO mice develop compulsive behaviors such as excessive barbering, grooming and wheel-running. Excessive activities were reversed by 3 weeks of 17beta-estradiol replacement. Interestingly, the presentation of compulsive behaviors is accompanied by concomitant decreases (p < .05) in hypothalamic COMT protein levels in male ArKO mice. These values returned to normal upon 17beta-estradiol treatment. In contrast, hepatic and frontal cortex COMT levels were not affected by the estrogen status, indicating region- and tissue-specific regulation of COMT levels by estrogen. No differences in COMT levels were detectable between female animals of both genotypes. CONCLUSIONS: This study describes the novel observation of a possible link between estrogen, COMT and development of compulsive behaviors in male animals which may have therapeutic implications in obsessive compulsive disorder (OCD) patients.

Obsessive compulsive behavior, hyperactivity, and attention deficit disorder in Sydenham chorea.

The authors investigated obsessive-compulsive behavior, obsessive-compulsive disorder (OCD), and attention deficit and hyperactivity disorder (ADHD) in 50 healthy subjects, 50 patients with rheumatic fever without chorea, and 56 patients with Sydenham chorea. Obsessive-compulsive behavior, OCD, and ADHD were more frequent in the Sydenham chorea group (19%, 23.2%, 30.4%) than in the healthy subjects (11%, 4%, 8%) and in the rheumatic fever without chorea group (14%, 6%, 8%). ADHD was more common in persistent Sydenham chorea.

Compulsive behavior and eye blink in Prader-Willi syndrome: neurochemical implications.

Compulsive behavior in Prader-Willi syndrome is well-documented, though the neurochemical basis of these behaviors remains unknown. We studied a group of 16 people with Prader-Willi syndrome and a comparison group of 19 people with intellectual disability. Using eye-blink rate as an indirect measure of central nervous system dopamine, we found a higher eye-blink rate in the Prader-Willi syndrome group and a relationship between compulsive behavior and eye-blink rate across both groups. Our findings indicate a relationship between compulsions and an indirect measure of dopamine in people with intellectual disability. Our findings may provide evidence for a gene-brain-behavior link between dopamine levels and GABAergic mechanisms in individuals with Prader-Willi syndrome.

Linkage analysis for autism in a subset families with obsessive-compulsive behaviors: evidence for an autism susceptibility gene on chromosome 1 and further support for susceptibility genes on chromosome 6 and 19.

Although there is considerable evidence for a strong genetic component to idiopathic autism, several genome-wide screens for susceptibility genes have been carried out with limited concordance of linked loci, reflecting numerous genes of weak effect and/or sample heterogeneity. In the current study, linkage analysis was carried out in a sample of 62 autism-affected relative pairs with more severe obsessive-compulsive behaviors, selected from a larger (n=115) set of autism-affected relative pairs as a means of reducing sample heterogeneity. Obsessive-compulsive behaviors were assessed using the Autism Diagnostic Interview-Revised (ADI-R). In the sample with more severe obsessive-compulsive behaviors, multipoint NPL scores above 2 were observed on chromosomes 1, 4, 5, 6, 10, 11 and 19, with the strongest evidence for linkage on chromosome 1 at the marker D1S1656, where the multipoint NPL score was 3.06, and the two-point NPL score was 3.21. In follow-up analyses, analyzing the subset of families (n=35) where the patients had the most severe obsessive-compulsive behaviors generated a multipoint NPL score of 2.76, and a two-point NPL score of 2.79, indicating that the bulk of evidence for linkage was derived from the families most severely affected with obsessive-compulsive behaviors. The data suggest that there is an autism susceptibility gene on chromosome 1 and provide further support for the presence of autism susceptibility genes on chromosomes 6 and 19.

Normative and pathological obsessive-compulsive behavior and ideation in childhood: a question of timing.

This study was designed to test whether obsessive-compulsive behavior declines over development. A cross-sectional design was used on a large community sample of children. Children in grades four, six, and eight (N = 1083), 8 to 14 years of age, were administered the Maudsley Obsessive Compulsive Inventory (MOCI) and the Spielberger State Trait Anxiety Scales. Whereas the mean MOCI score was significantly lower in the eighth grade than in the sixth and fourth, there was an elevation of children with very high MOCI scores in the eighth grade. Obsessive ideas and compulsive behaviors that were common for fourth-grade children were present in only a minority of children in the eighth grade, and were associated with high levels of anxiety. No gender differences were observed for overall obsessive-compulsive behavior, but checking behavior was higher in boys, and cleaning behavior in girls. State anxiety was higher in girls than in boys, and was also higher in older than in younger children.

Maladaptive and compulsive behavior in Prader-Willi syndrome: new insights from older adults.

Although maladaptive and compulsive behaviors are increasingly well-described in young persons with Prader-Willi syndrome, it is unclear how these problems manifest in older adults with this syndrome. In Part I, I compared maladaptive and compulsive behaviors in 45 older adults with Prader-Willi syndrome (ages 30 to 50 years) to 195 children, adolescents, and young adults. Young adults were at highest risk for problems. In contrast, maladaptive and compulsive symptoms diminished significantly in older adults with Prader-Willi syndrome. In Part II, I examined predictors of problems other than age: IQ, gender, BMI, and-for adults-living status. Gender and BMI were significant predictors of skin-picking and other symptoms. Possible reasons are discussed for sweeping declines in problems among older adults.

Error-related electrocortical responses are enhanced in children with obsessive-compulsive behaviors.

The error-related negativity (ERN or Ne) and positivity (Pe) are event-related potential components elicited during simple discrimination tasks after an error response. The ERN and Pe have a fronto-central scalp distribution and may be an indirect measure of anterior cingulate (AC) activity as it relates to performance monitoring. Brain imaging studies suggest that obsessive-compulsive disorder (OCD) is associated with exaggerated activity of the AC while electrophysiological studies have found an association between OCD and pronounced ERNs in adults. The present study explored the relation between obsessive-compulsive behaviors, the ERN, and the Pe in a sample of nonclinical 10-year-old children. It was found that more parent-reported obsessive-compulsive behaviors were associated with larger ERN and Pe components in the children. Results suggest unique contributions of the ERN and Pe in predicting obsessive-compulsive behaviors.

Animal models of compulsive behavior.

A convergence of clinical and pathological evidence points to the basal ganglia as the site of disturbance in compulsive disorders. However, the limbic system may be implicated as well. This article draws upon various lines of animal research in an attempt to explain how disturbances in one or another of these systems may produce compulsive behavior. Possible models include stimulation of the reinforcement mechanism, manipulation of the striatal "comparator" function, production and blockade of displacement behavior, and interference with the hippocampus' modulation of the stereotypy-inducing effect of reward. The common denominator of these models is a relative excess of dopaminergic activity in the basal ganglia. However, this does not necessarily implicate a primary dopaminergic disturbance in all human compulsive behavior.
