"So, should I medicate my child?" helping parents determine when medication may be effective and how to navigate the pharmaceutical choices Joshua D Feder, MD Faculty, Interdisciplinary Council on Developmental and Learning Disorders Assistant Clinical Professor, Department of Psychiatry, University of California at San Diego, School of Medicine January 23, 2008 at Crimson Center for Speech & Language 9606 Tierra Grande #107 San Diego, CA 92126 Preamble How is this handout different from my prior handouts? • So many similar talks – so what’s new? • I considered adding jokes: monster under bed, stealing… • Research: mirrors, joint attention, GxE • Updated meds appendix (to include steroids) • This time it’s about whether to medicate, all else is commentary… Ambling... Being stuck. • Most people consider meds because they feel stuck, maybe desperate • Emergencies: aggression, depression, others? • Lack of progress: in what areas? What kind of progress is important? • What do you want for your child? • What the meaning of the disability is to you and to your child? • Goal: a meaningful life socially, emotionally, and cognitively. • Requires a plan, and medication alone is not a plan. Do I have good enough program in place? • regulatory issues/ motor and sensory areas addressed • engagement and reciprocity • language/ communication • cognition/ learning • daily living skills followed by broader and broader areas of life skills, from
school and playground to vocational skills.
Current trends in research: • Mirror neuron systems • Joint attention and relationship-based intervention • GxE: genetics and environment The Impossible Program: • Are you asking too much of the child? • Of the family? • Of the school? Will meds work? • Is the program adequate? • Will they change my child’s brain and fix it? • Will they injure my child? • What should I expect? Why wait at all? • Losing time while pulling the program together • Doing as much as possible • Awakenings – should we go for a miracle? Coming to rest Every family is different • We do not know enough to say ‘you really should medicate’ • If there is no emergency, you have more time to think about it • When parents differ, if makes for more thoughtful planning Notes:

Appendix C Summary of Greenspan on Empathy (5/04 podcast): Empathy is not inborn. It’s not like fear or anger, but more like love and compassion. The mechanisms are there to develop it, but it depends on the person’s experiences to develop. A truly empathic person can understand how another person feels; tunes in and listens and truly understands and is there w/ you – emotional tone, posture convey can be in your shoes and make you feel better but not so much that they exaggerate your feelings not just a few mechanical questions w/out the feeling level beyond intellectually. Can be taought to any child, and if you start late it is harder to do but it is still possible. level 1 - Shared Attn and Regulation (0-3 months): • First relationship, experience empathy for the first time level 2 - Engagement and Relating (2-6 mo) • Depth of that relationship is the depth of empathy. level 3 - Two-Way Purposeful Communication (4-9 mo) • Reading and responding to emotional signals at 8-9 mo • Sense them and feel them in the body, physically level 4 - Shared Social Problem Solving (9-18 mo) • Negotiating problems – 18 mo • Beginning of cooperative, collaborative interaction – 18 mo • Shared humor between toddlers at 18 mo • Behavioral evidence of altruism: pat mommy’s arm (may be imitation at this point), also around 18 mo level 5 - Creating ideas (18-30 mo) • Shared pretend play at a symbolic level • Shared world of emotions – joy, anger, sadness, etc. • Child not only feels empathically but can think empathically. level 6 - Building Bridges Between Ideas: Logical Thinking (30-48 mo) • Cause and effect: asks why you feel that way • Can separate his internal world from your world, and still feel concerned level 7 - Multi-Cause Comparative Thinking (4-6 yr) • Mom’s mad, bad day at work, but asks if there are other reasons.
level 8 - Emotionally Differentiated Gray-Area Thinking (6-10 yr) • Hierarchies, playground politics • The best time for disappointment – better to lose now and have mom’s support than to lose as an adult and have no experience to fall back on. • Emotional experiences define, expand, and deepen the boundaries for the self. Without anger we don’t know what annoys us, without joy we don’t know what makes us happy. • Refining the gradations of these emotions • This expanded and deepened appreciation for emotional experience makes us more able to appreciate it in others. level 9 - Intermittent Reflective Thinking, A Stable Sense of Self, and an Internal Standard (9-12 yr and beyond) • Really adolescence and beyond… • the ability to empathize in a truly reflective manner • able to understand a range of feeling in others and compare it to your stable sense of self, retaining who you are • helps you to be truly a great friend or partner. • Reflecting on yourself and others w/o taking over nor removing yourself • Expanding sense of empathy, more and more inclusive: other kids, groups, school, country, … the world (other races, religions, etc.). Advice, in general in working with people with special needs, is to provide more than usual opportunites for experiences that reflect empathic thinking, in pretend play and everyday life, asking about what others might be feeling, asking opinions and avoiding rote thinking.

Appendix D Medication for the Treatment of Autism and Autism Spectrum Disorders Many families wonder about the use of medications to treat autism and related disorders (ASDs). For decades doctors have been using many different medications ‘off-label’ to treat various symptoms of these disorders. In 2007 one medication, risperidone (Risperdal) was given the first FDA approval for marketing a medication for autism, specifically for the control of aggression. Medication can sometimes be very helpful, making it possible to utilize other treatments more effectively. At their best, some people have remarkable improvement in social awareness. However, medication cannot make up for an inappropriate placement or poor staff training. Also, families need to weigh the benefits of medications against side effects and work closely with the prescribing physician. Here are examples of medications and classes of medications often used: Neuroleptics (Antipsychotics): These medications have the most research about their use in persons with ASDs. All are FDA approved for schizophrenia, but virtually all can help with mood stabilization in bipolar illness and with mood stabilization and aggression in ASDs. Neuroleptics are very helpful for tic disorders (Tourette’s, etc.). These medications can also occasionally create significant improvement in social function, leading many doctors to recommend them as first line treatments for ASDs. These are, however, powerful medications and side effects, depending on the medication, can include weight gain, insulin resistance, sedation, agitation, changes in cardiac conduction, higher risk for seizure, new abnormal movements and muscle spasms (dystonias, Tardive Dyskinesia), and rarely a dangerous fever with muscle stiffness (Neuroleptic Malignant Syndrome). These medicines are often used safely but require good follow up and good communication between family and the physician. Members of this class include chlorpromazine (Thorazine), molindone (Moban), fluphenazine (Prolixin), thioridazine (Mellaril), haloperidol (Haldol), trifluoperazine (Stelazine), etc.; and the new: clozapine (Clozaril), risperidone (Risperdal), olanzapine (Zyprexa), quetiapine (Seroquel), ziprasidone (Geodan), and aripiprazole (Abilify). Serotonin Specific Reuptake Inhibitors (SSRI’s): These medicines are often used with persons with ASDs to target depression, anxiety, obsessiveness/perseveration, and rigid thinking. While often helpful, they also frequently create ‘behavioral activation’, i.e., make the person more active and impulsive. This can interfere with learning. People sometimes gain weight on these medicines over time (many months or years). People at risk for manic episodes can become manic or hypomanic on these medications. These medicines can also raise seizure risk, and in combination with other medicines (MAOIs, buspirone, etc.) can create a risk for a potentially dangerous Serotonin Syndrome. Again, used with care these medicines can be very helpful. The SSRI’s include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), fluvoxamine, citalopram (Celexa), and escitalopram (Lexapro).
Stimulants: These are the medications most used for Attention Deficit Hyperactivity Disorder (ADHD), and given the apparent genetic overlap between ADHD and autism, and the frequency of ADHD symptoms in persons with ASDs, it makes sense to consider these medications too. While early studies found them ineffective in autism, more recent work and clinical experience shows they can help with inattention and overactivity in some persons with ASDs, but they do tend to have more trouble side effects. Side effects can include loss of appetite, sleep disturbance, irritability when the medicine is wearing off, tics, increased sensory sensitivity, increased obsessiveness/ perseveration or rigid thinking. Stimulants are a good example of a class of medication that can often be used with good effect when in combination with another medicine that balances the side effects, and equally a good example of medications that are pretty safe but easy to dislike because of side effects. Most stimulant medications in use are different packing and delivery systems of either methylphenidate or dextroamphetamine. Names of methylphidate type medications include Ritalin, Metadate, Methylin, Concerta, Focalin, and Daytrana. Dextroamphetamine type stimulates include Adderall, and ‘mixed amphetamine salts’. A ‘prodrug’ called Vyvanse has just been releases on the market. It becomes dextroamphetamine once in the body and may have less street value because of this. Despite real concerns about addiction to stimulants, it is important to note that most people are not as risk for addiction and, when used appropriately, the risk of substance abuse for people with ADHD using these medicines is actually lower than expected, presumably because they make better decisions. In any case, people treated with stimulants require cardiovascular screening and follow up (history, blood pressure, pulse) as well as monitoring of weight and growth as these can be affected (likely due to reduced appetite). Tricyclic Antidepressants, such as clomipramine (Anafranil), imipramine, desipramine (Norpramin), nortriptyline (Pamelor), and amitriptyline (Elavil) are older medications that some people still use for depression and anxiety, inattention,and bedwetting. While clomipramine can be an excellent medication for obsessive-compulsive symptoms too, these medicines require careful cardiac monitoring and can be cardiotocix in overdose and must be used with caution. Norepinephrine-Serotonin Reuptakes Inhibitors: these include venlafaxine (Effexor), mirtazapine (Remeron), duloxetine (Cymbalta), and nefazadone. They are ‘dual-action’ antidepressants and as a class they tend to be about as effective as SSRI’s for depression but often have less activation associated with them. Cautions are similar to SSRIs with additional need to monitor blood pressure if there is already a concern for high blood pressure. Bupropion (Welbutrin) is another antidepressant that is dopaminergic and therefore in a class of it’s own. Like stimulants, which also affect dopamine systems, it tends to help focus and concentration, reduces craving for carbohydrates (and also tobacco and
alcohol), and may have a place for some persons with ASDs who otherwise lack energy as they are generally activating. They also increase seizure risk in those who are susceptible (with ASDs, the more challenged the person is the higher the seizure risk, also there seems to be an increased risk in the teenaged years for seizures in persons with autism). Antiseizure medications, also known as Antiepileptic Drugs or AED’s, include valproate (Depakote), carbamazepine (Tegretol), lamotragine (Lamictal), oxycarbazine (Trileptal), topiramate (Topomax), gabapentin (Neurontin), ethosuccimide (Zarontin), and others. These are medications used for various kinds of seizures and all, to some degree, are used for mood stabilization in persons with Bipolar Disorder. They are often used to help persons with ASDs attain better mood stability, however they all have different side effects and many require blood levels. A full discussion is not possible here, but it is important that your doctor knows and discusses with you the various options and ways these medications are prescribed. As a class, AEDs are also often quite useful in the treatment of persons with ASDs, particularly when there is suspicion that part of the underlying difficulty includes subclinical seizure activity that makes the person seem unfocused and at times unruly. Often a 24 hour EEG and a neurologic evaluation are helpful in deciding whether to try these medications. Central Alpha Agonists such as guanfacine (Tenex, Guanfacine XR) and clonidine (Catapres) are medicines that were originally marketed for high blood pressure in adults but because they reduce the ‘fight-flight’ function of the autonomic nervous system they have a role in the treatment of many other disorders. These medications can help with attention and focus, reduce tics and sensory sensitivity, and generally calm people with ASDs. They can also make people sleepy, dizzy, or cranky. Used with care these medicines are usually helpful, and often used in combination with other medications such as stimulants. Atamoxetine (Strattera) is a non-stimulant medication for ADHD, that is a lot like an NSRI and carries similar cautions to NRSI’s and SSRI’s. Like with all persons with ASDs, some people respond well, others have significant side effects, e.g. agitation. Benzodiazepine medications such as diazepam (Valium), alprazolam (Xanax), clonazepam (Klonopin), and lorazepam (Ativan) are excellent anti-anxiety medications, but they tend to interfere in learning, memeory, and coordination, and they can be addicting for both persons with ASDs and for family members who might borrow them, and their role in the safe treatment of ASDs is limited by these cautions. Naltrexone (Revia) is an opioid antagonist used in the treatment of alcohol and drug addiction, which has also been tried for persons with ASDs, specifically to help with self-
injurious behaviors. While no good research studies have proven that this helps controlled populations, but like with most treatments for ASDs, there are scattered reports of good success attributed to naltrexone. Liver function should be monitored. Memantine (Namenda) is a medication marketed to help persons with Alzheimer’s Disease retain cognitive function, and there are now several reports of its use in persons with ASDs, again with scattered reports of success in improving cognitive function. While it appears to be fairly safe, the long term effects of the use of this medication, like with most medications, particularly in developing children, is unknown. Steroid Treatment: Some doctors prescribe courses of steroids, usually Prednisone, and usually to infants and very young children with autism or with sudden regression of development, whom they believe may have a variant of Landau-Kleffner Syndrome (LKS). LKS is a disorder typically seen in infants or very young children who have severe seizures, and the steroids seem to help some of them stabilize and allow for more normal development. The treatment has potentially serious side effects which must be discussed with your doctor, although different methods of timing the steroids can help reduce side effects. This is by no means an exhaustive list as there are many other medications used in the treatment of ASDs. It is important to work closely your doctor, to avoid rapid or large or multiple changes in medication if possible, and to be sure to look at the entire range of interventions for the person rather than to become focused on medication as the ‘answer’ to the many many challenges of living with Autism and autism spectrum disorders.
