Friday Factoids Catch-Up: New Treatments For Tic Disorders Associated With Tourette’s

 

Tics, which are characterized by sudden, repetitive, non-rhythmic body movements and/or vocalizations associated with tic disorders and Tourette’s syndrome, are involuntary movements that may involve the hands, shoulder shrugging, eye blinking, etc.  In many cases, these tics do not get in the way of living a relatively normal life and consequently little if any treatment is required.  At the other end of the spectrum, the tics may be so severe that they require treatment with medication and behavioral therapy, especially if they are causing pain/injury, are interfering with a normal daily routine in one’s education, job performance, or social life, or are responsible for inducing excessive stress. Prior to the treatment of the presenting tics, the presence of other movement-related disorders like chorea, dystonia, as well as the movements displayed by those with autism (stereotypic movement disorder), or those movements manifested as compulsions of OCD or seizure-related activity, must be ruled out to ensure the patient receives the proper care and treatment that is best suited to address his or her needs.

 

There are various methods for treating the tics that are so often associated with Tourette’s syndrome, including medication, behavioral therapies, and habit reversal.  While medication is most often the go-to panacea for controlling tics, the medications themselves may carry side effects that are as bad, or even worse, than the condition that they may be used to treat.  Behavioral therapies can also be effective as well by teaching those with Tourette’s to manage their tics.  While these can be effective in reducing the number, severity, and impact of the tic behaviors, it is important to realize that behavioral therapy is not a cure, and that although effective it does not mean that tics are merely psychological in their nature.  While these treatment methods are effective in aiding the treatment of, and helping to manage, the tic symptoms of Tourette’s syndrome, it is important to note that they are varied in their efficacy, are not one-size-fits-all in their nature, and in the case of medication, may produce unwanted side effects ranging from mild to debilitating in and of themselves.

 

One of the most promising methods recently developed for the treatment of tics associated with Tourette’s is the Comprehensive Behavioral Intervention for Tics, or CBIT.  This new, evidence-based therapy includes the use of education, teaching relaxation techniques, and habit reversal in a combination that is shown to be effective in reducing symptoms of tics and their related impairments, and seems to work equally well for both children and adults. CBIT involves those with Tourette’s working with a therapist to gain a greater understanding of their particular type of tic and learning to recognize situations that worsen tic symptoms.  When possible, a change in environment may be initiated, and using habit reversal, a new behavior is modeled so that when the urge to tic occurs, the new behavior is substituted.  This method helps to lessen tic occurrences through substituting the new behavior for the tic through repetition, under the guidance of an experienced therapist.

 

Over the last few years, the number of health professionals that have come to know and appreciate the benefits and effectiveness of CBIT has increased; however, there are still relatively few therapists that have the specific training in these methods of treatment targeted specifically at tic disorders and Tourette’s, and work is currently being done by The Tourette Association of America and the Centers for Disease Control and Prevention to provide education for more health professionals with the training necessary to incorporate and apply this method in their treatment approach to managing the symptoms of Tourette’s and other tic disorders.

Friday Factoids: Disruptive Mood Dysregulation Disorder

Disruptive mood dysregulation disorder (DMDD) is a newer diagnosis in childhood that is depicted by extreme irritability, anger, and frequent outbursts (National Institute of Mental Health [NIMH], 2016).  Irritability is a clinical symptom of both bipolar disorder and DMDD (Wiggins et al., 2016).  Comparatively, irritability in DMDD is “severe and relatively invariant over time,” yet irritability experienced with bipolar disorder may occur while a child is euthymic and may increase during manic or depressive episodes (Wiggins et al., 2016, p. 722). Thus the inclusion of DMDD in part allows for appropriate diagnosis for children with “severe, nonepisodic irritability” that is distinct from bipolar disorder (Wiggins et al., 2016, p. 722).

 

With DMDD being a new diagnosis, treatment is often based on other disorders with shared symptomatology (e.g., attention-deficit/hyperactivity disorder, anxiety disorders, oppositional defiant disorder, and major depression; NIMH, 2016). Cognitive-behavior therapy (CBT), parent training, and computer-based training are recommended psychological interventions (NIMH, 2016) for DMDD, where as medications may also be considered.  For instance, stimulants may help address irritability, antidepressants may mitigate irritability and mood problems, and atypical antipsychotics could be used to alleviate severe outbursts with physical aggression (NIMH, 2016).

 

The potential for adverse effects with some treatments limit their use in children, resulting in the necessity to explore noninvasive means for treatment (Wiggins et al., 2016).  For instance, the use of a video game to reduce the misinterpretation of ambiguous faces in children with irritability has shown to help reduce anger-based reactions found in DMDD.  The literature has shown that children with DMDD and bipolar disorder tend to rate neutral faces as angry (Wiggins et al., 2016). Research conducted by Wiggins et al. (2016) has demonstrated that a computer game helped to change the tendency to misinterpret ambiguous faces as angry in irritable children.  After training, children were more likely to rate ambiguous faces as happy (Wiggins et al., 2016).  Such an intervention may appear superficial, however this research has demonstrated that brain activation patterns when labeling emotional faces differs between DMDD and bipolar disorder (Wiggins et al., 2016).  Specifically, amygdala activation related to irritability differed between children with DMDD and bipolar disorder; and temporo-occipital regions of the brain had “associations between irritability and activation in response to ambiguous angry faces” (Wiggins et al., 2016, p. 728).

 

Thus, differing brain activation patterns helped distinguish the clinical presentation of DMDD versus bipolar disorder (Wiggins et al., 2016).  As a result, the authors conclude that though irritability is a common symptom of both DMDD and bipolar disorder, they are in fact distinct disorders and given the different neural correlates, treatments may also be different (Wiggins et al., 2016).

Friday Factoids: Methamphetamine Psychosis

 

As reported by the National Institute on Drug Abuse (NIDA; 2013) methamphetamine use continues to be a significant problem, with over 12 million people or 4.7 percent of the population having tried methamphetamine at least one time.  According to NIDA (2013), methamphetamine use can cause memory loss, aggression, psychotic behavior, damage to one’s cardiovascular system, malnutrition, and dental problems.

 

Chronic use may cause an individual to have difficulty feeling pleasure outside of use, as well as anxiety, confusion, insomnia, mood disturbance, and violent behavior. Psychotic features experienced include paranoia, delusions, and visual, auditory, and tactile hallucinations.  Stress has also been related to spontaneous methamphetamine psychosis in individuals who have abused methamphetamine in the past (NIDA, 2013).  With acute methamphetamine intoxication individuals may experience hallucinations (auditory, visual, tactile), persecutory, influence, and control delusions, as well as are prone to violence (Zarrabi, Khalkhali, Hamidi, Ahmadi, & Zavarmousavi, 2016).

 

Even after intoxication passes, psychosis may occur over a prolonged period of time (Zarrabi et al., 2016).  Acute psychosis usually has a maximum period of four to five days (Zarrabi et al., 2016); yet, a differing course of psychosis has been documented in the literature. For instance, three clinical groups for stimulant-induced psychosis have been identified:  the first group is characterized by transient psychosis, where the duration of symptoms is limited to four or five days and may be associated with withdrawal; with the second group, psychosis is typically resolved in less than one month; and in the third group, psychosis may last several months or years (Zarrabi et al., 2016).  It has been estimated that between 5-10% of individuals with methamphetamine-induce psychosis may not fully recover (as cited in Zarrabi et al., 2016).

 

Risk factors for methamphetamine-induced psychosis are duration, frequency, and amount of use, history of sexual abuse, family history, other substance use, and co-occurring personality and mood disorders (Grant et al., 2012). Of note, substance intoxication is differentiated from a substance/medication-induced psychotic disorder if reality testing for altered perceptions remains intact (American Psychiatric Association, 2013).

 

Zarrabi, Khalkhali, Hamidi, Ahmadi, and Zavarmousavi (2016) indicate there are no structured treatment guidelines for methamphetamine-induced psychosis.  In their study, risperidone and olazapine were most frequently used, as well as benzodiazepines to reduce restlessness. Antipsychotics were reportedly preferred due to better control of violent behaviors.  Another study indicated that quetiapine could also be used as an antipsychotic treatment with comparable effects to haloperidol (Verachai et al., 2014). Electroconvulsive therapy (ECT) has been used to control severe aggression and violent behaviors, as well as thoughts of suicide and homicide in methamphetamine-induced psychosis (Zarrabi et al., 2016).  Results indicated that after six to nine sessions of ECT, symptoms began to disappear.  Though limited by constraints of a case study, Grelotti, Kanayama, and Harrison (2010) again demonstrated the positive effects of ECT on methamphetamine-induced psychosis.

 

Overall, the most common symptoms with methamphetamine-induced psychosis are paranoid delusions and auditory hallucinations, and such symptoms may prove resistant or refractory to antipsychotic medications (Grelotti, Kanayama, & Pope, 2010).  As indicated in the literature, clinicians faced with refractory cases of methamphetamine-induced psychosis may consider ECT as a treatment option.
