Autism and Drugs

This kind:

...not this kind:
Like many parents, I would rather not use drugs on my child unless absolutely necessary. On the other hand, I believe they might be useful with some children in augmenting behavioral intervention programs, sensory integration techniques, and occupational or physical therapy. Temple Grandin, a high-functioning autistic herself, has some great advice on the use of drugs for the treatment of autism: http://www.autism.org/temple/meds.html

During James’s first visit with the neurologist, back when he was four, we discussed ADHD medication. James’s neurologist mentioned that a lot of his PDD patients that had speech delay also had ADHD characteristics; on the other hand, he thought James was too young, and I also wanted to give James a break and wait. (See the blog on “Dr. Kendal Stewart” for our experience with Valtrex and Strattera.)

Last December, when he was five, James began to exhibit more aggressive behavior. Today James is in a “Functional Life Skills” program, and we are still working on his behavior issues. Although he can academically do most of the work assigned to him, he is impulsive, “testy” or defiant, often refuses to work, needs constant redirection, and hits other children on a regular basis—behaviors that are keeping him out of the mainstream classroom.

Because I was hesitant to jump right into ADHD medications, I went to a nutritional oncologist who recommended nutritional supplements often used for increasing serotonin levels. This did not work so well. I stopped his supplementation after five months.

A few months ago James’s neurologist and I discussed using a norepinephrine antagonist, Catapres (Clonidine), as a safer, milder alterative to ADHD medication; something to take the edge off of his tantrums and aggressive behaviors. After trying Clonidine for a month, we met again and looked at James’s aggressive behavior and obsessive-compulsive tendencies.

The clonidine seemed to help a little bit. We also discussed two other stronger classes of drugs, neuroleptics for aggression and antidepressants for obsessive-compulsive tendencies. For the time being we’ll stick with Catapres because of the lower risk.

I’ll go into a bit more details on these five classes of drugs. Here they are, as grouped by lower-risk, higher risk:

Lower Risk :
Nutrients affecting Methylation, Serotonin Production
Norepinephrine Antagonist

Higher Risk:
Neuroleptics
Serotonin-Selective Re-uptake Inhibitors (SSRI), or “Antidepressants”
Stimulants (ADHD drugs)


Nutrients affecting methylation of Serotonin
TMG (tri-methyl-glycine)
DMG (di-methyl-glycine)
5-HTP (5-hydroxy-tryptophan),
SAMe (S-adenosylmethionine)

Serotonin (5-Hydroxytryptamine, 5-HT) is an important neurotransmitter that affects mood, hunger and sleep. TMG breaks down into DMG and SAMe. TMG, DMG, 5-HTP, and SAMe are nutritional supplements (therefore not regulated by the FDA) commonly used to enhance the methalation of serotonin.

Companies that sell 5-HTP claim that it “passes into the brain immediately” or “easily crosses the blood-brain barrier”, while tryptophan “must compete with other protiens [sic; amino acids] to be transported across the blood-brain barrier.” But there seems to be challenges to this claim (see http://www.ceri.com/rev-sero.htm), which makes me skeptical.

Nevertheless, after meeting with a nutritional oncologist for a couple of hours, I put James on daily regimen of TMG, 5-HTP, and “pharmaceutical grade” lecithin supplements for over five months. (Extremely low risk.) Unfortunately, I observed no significant changes. When I discussed this with our neurologist, his opinion was that 5-HTP and tryptophan simply does not work because increasing serotonin levels isn’t enough for many people. Instead, establishing the correct ratio of serotonin at the brain synapses is what is important.

Although I’m sure many people have benefited from 5-HTP, DMG, TMG, and SAMe (I’ve talked to some that swear by it), James does not seem to fall into this category.

James does take two types of liquid vitamins which certainly don't hurt:
Liquid Health™ Children's Multiple and
Liquid Health™ Children's Attention



Serotonin-Selective Re-uptake Inhibitors (SSRI), or “Antidepressants”
In contrast to 5-HTP and SAMe, which work by increasing the overall amount of serotonin in the body, Serotonin-Selective Re-uptake Inhibitors (SSRI), or “antidepressants,” such as Prozac and Zoloft, work by changing serotonin ratios within the brain. Only one or two percent of the serotonin in the body is in the brain, and that amount is independently synthesized from tryptophan transported across the blood-brain barrier. SSRIs raise serotonin levels within the brain by inhibiting the reuptake (recycling) of serotonin.

SSRIs are commonly prescribed as a treatment for Obsessive/Compulsive Disorder (OCD). Many PDD and autistic children exhibit obsessive-compulsive behaviors, such as impulsiveness, repetitive preoccupations, and perseveration. James’s speech and physical/occupational therapists have noted that his obsessive/compulsive tendencies are strong, even when compared to other autistic and ADHD children they have encountered in their practice.

Unfortunately, the side effects associated with Prozac and Zoloft can be rather severe. Because of James’s age and other factors, I’m not going to try SSRIs at this point but have not ruled them out for future evaluation.

Stimulants
According to James’s neurologist, a lot of kids that are autistic/PDD with speech delay tend to exhibit ADHD characteristics. Many of these children are on ADHD drugs (stimulants) such as Ritalin and Adderall.

Although ADHD children are hyperactive, stimulants at the dosages used for ADHD can appear to calm many hyperactive children. Although how stimulants exactly do this still isn’t exactly known, many studies and a lot of research indicates that stimulants work primarily by increasing dopamine levels in the brain. Dopamine helps regulate inhibitions but also promotes feelings of well-being and satisfaction. Stimulants also enhance levels of the neurotransmitters serotonin and noradrenaline (norepinepherine), which can help regulate impulsiveness. Stimulants have been also shown to increase the blood flow in the brain and neural activity in the frontal lobes.

I have known several children and adults who have taken these drugs, and their experience varies. For example, James’s uncle said it would always have him feeling “sick” or “not right,” so he would spit the pills out; on the other hand, my nine-year-old neighbor is doing great on it. Some of these variances may be due to quality of dosing and appropriate “matching” of the drug to the individual: you’ve got to remember, except for Strattera, most ADHD drugs are stimulants. Cocaine and methamphetamines are stimulants and share some of the same pharmacological effects as ADHD medication; then again, so does caffeine.

I’ve also noticed that some of the people who complain about ADHD drugs the most are parents or kids who felt coerced somehow by school districts. Schools can no longer do this. ADHD medication isn't for everyone and should always be used in conjunction with therapy, not as a substitute for it. I haven’t had this type of experience with the school so far; they’ve been helpful in providing me with observational data and seem to respect the parents’ choices. James’s neurologist did warn me that ADHD drugs are often hit-or-miss, and it may take a few tries to find one that works at the proper dosage. We still don’t know if ADHD medication would help James or not.

Even some ADHD kids don’t respond well to any ADHD stimulant; those kids may have to try the family of tricyclic antidepressants (TCA’s) instead. (Antidepressants will be discussed later in this posting—specifically, the family of atypical antidepressants.) Another alternative to stimulants is Strattera (atomoxetine): unlike stimulants, which works primarily by increasing dopamine levels, Strattera works by increases norepinephrine levels in the brain. While under the care of Dr. Kendal Stewart, James tried Strattera for two weeks because of a study linking Strattera with improved speech. It had no effect. When I mentioned this to my neurologist, he urged me to stop for three reasons: James was only four at the time, the study wasn’t compelling enough, and Strattera was very new. Several months later the liver damage lawsuits came to light, so we won’t be trying Strattera again.

The last thing I want to do is turn James into a zombie or stress his body out at a young age. I have mixed feelings about going down the ADHD drug route, and many people have strong feelings both ways. I do not believe it is necessary for us at this time, but I have not ruled it out for future use. As James matures and progresses in school I’ll keep re-evaluating, and do a bit more research in this area. The day may come when we will have to try ADHD medication, but only for the right reasons.

Neuroleptics
Atypical Neuroleptics (a.k.a. Atypical Antipsychotics) target dopamine and serotonin receptors, which control behavioral problems such as self-injury, aggression, hyperactivity, and tantrums. Common side effects include weight gain. Rare but serious side effects include neuroleptic malignant syndrome (very rare but serious neuro-muscular rigidity symptoms, sometimes life-threatening) and tardive dyskinesia (motor dysfunctions, such as tongue movements, facial tics).

Of the following Atypical Neuroelptics:
Risperdal (risperidone),
Seroquel (quetiapine),
Zyprexa (olanzapine),
Zeldox (ziprasidone), and
Clozaril (clozapine),

James’s neurologist recommended that if we were to try a neuroleptic, consider Seroquel because of reduced side effects. James does exhibit some aggressive behavior at school, but a lot of it can still be controlled simply through redirection and discipline. The milder Clonidine (a norepinephrine antagonist, not a neuroleptic) that James is taking seems to be helping, so I’m going to wait before going to something stronger—again, the side-effects are a big concern for me. I’m also still trying to figure out if his aggression is more related to his obsessive-compulsive traits, environment, or other social factors.

Norepinephrine Antagonist
Since norepinephrine agonists such as amphetamines or methylphenidate have been shown to worsen autistic behaviors, one rationale for using a norepinephrine antagonist such as Catapres (clonidine hydrochloride USP) is that it could reduce autistic behaviors. Several double-blinded placebo-controlled studies in the 1990s appear to confirm this.

Catapres (clonidine) is commonly used for reducing hypertension and is an extremely safe drug, easy on the liver and kidneys. Clonidine basically has a mild calming effect, and has been demonstrated to be effective also as a sleeping agent (mild sedative). The effects are short (four to five hours), so it is typically dosed early in the morning and at noon.

Although clonidine is not as strong as stimulants (ADHD medication), neuroleptics (antipsychotics), or antidepressants, the negative side effects are generally mild and low risk. (They are “easy on the organs.”) It has to be taken at reduced dosages for a couple of weeks at the beginning and end of treatment; otherwise, blood pressure will drop at the beginning or rise when abruptly stopped. It also has to be taken regularly for similar reasons. Blood pressure and heart rate should be monitored regularly, especially during the two weeks or so it takes to come on and off the drug. Other than low blood pressure, the main side effects are fatigue and sleepiness. Since the body can get used to it, its effectiveness may be reduced over time.

James has been on clonidine for over a month now (started on October 30th). Although it hasn’t given anyone a “Wow!” effect, I’ve seen a few mild positive changes: he sleeps longer at night, and goes to bed earlier; he is a little bit easier to redirect; his tantrums are shorter, milder. The change is subtle but noticeable also by his teachers, therapists, and myself. Although feedback from his therapists has been positive, his teacher at school (where he spends the most time) did say that although the intensity of his behaviors has decreased slightly, and his tantrums are milder, he is misbehaving more often. He is also coming up with progressively worse negative behaviors, such as throwing objects at the window (used to throw at wall), picking up computers (rather than just pushing them).

Oh well, medication isn’t going to solve everything.

For now, I’m going to stick with it a little longer. Even a 10% improvement is worth it, since the risks with this drug are low. Also I’ve noticed that around this time of the year—when it gets darker and the temperature drops—he can work himself into these giddy, manic fits where he won’t stay still, can’t be held still, gets into everything, and won’t make eye contact even if you’re right up in his face. It’s similar to but not quite a “glazed” look. His speech therapist summed it up rather well: “it’s as if he isn’t with us today.” Two weeks or so before we started clonidine he had a few episodes like this, and I thought, “Oh no, not again.” But this hasn’t happened since. I’m not sure if it is the clonidine, or if it’s just on his own. I’ll probably stick with it at least a few more months, until it gets warmer, with longer days (early Spring). Last Winter was especially bad.

Wow. Thanks for all that great information. I read your Blog often and applaud everything that you do for your son. My son is PDDNOS and is 2 1/2 years old. Although our sons are far apart age wise, I value reading about older children who have Autism and the victories and struggles that they and their parents go through. There isn't much out there about kids with Autism after they pass the age of 5. Keep up the great work.

Hi there my name is Kiralea i live in Australia Sydney. I am new at blogging though i have managed to finish so far what i started out to accomplish. Your information is just fantastic. As parents of these special individuals you can never do enough research into finding out what may be best for our children.I am the mother of 3 and all 3 have different challenging aspects of life that awaits them to conqour. As i am new to this ring I hope you will get the time to read my story about Jordan who is Autistic, Nicolas has just been diagnosed with OCD, ODD & mild aspergers, and our daughter who was born with a rare chromosone disorder. Our blog page is jordanpowell.bloggers.com or under the surf ring Jordan story. Thankyou for adding so much useful information about aspergers, this sheds a new light on Nicolas behavioural problems that we are still learning and understanding about because Jordan and he are two different kettle of fish. Take care and thanks again. Kind regards Kiralea

hi, Jason Powell here. Father of Jordan Powell. You recently commented on my wifes blog about Jordans bus scenario with suspected abuse.
I have just read your blog with my wife and can appreciate your efforts in raising James on your own.
It's like looking into a mirror at times (with regards to bahaviours) and makes us realise the struggles we have all gone through. (primarily my wife, while i'm at work)
Having to fight the system to find the right solutions to your childs needs is frustrating but in the end it is all worth it. Only the parents have a real insight to their childs needs are and without our help they would be even more helpless.

Keep up the good work and we'll keep reading your sight with great anticipation.

Hi, my name is John. I came across your blog because I am doing research on something to help my 6 yr old son (with autism) and his tantrums, which are part panic attacks. His doctor recommended 5HTP but I am skeptical just like you. I was wondering if you had ever considered Effexor, which supposedly is a cross between Prozac and something that would help "panic attacks". I know some people out there wont like me for thinking about this, but his behavior at the mall is starting to get really out of hand. Yes, I have tried everything else. You mention it, and I'll bet we have tried it. If you have time please write me at evans6removethis2@hotmail.com, just delete the removethis before sending.

Hi James Short -

I'm brand new to your blog, but have you considered trying anti fungal agents for the aggression your son is exhibiting? My son used to attack any child who made a loud noise and many children for no apparent reason; this included newborns and infants. He was also banging his head 50+ times a day and we were going insane along with him.

We saw nearly all of his unprovoked aggression and head banging dissipate when we started Nystatin and enzymes. Testing for yeast infections is relatively simple and many, many autistic children have intestinal yeast issues. Beware, if you son exhibits behavior like ours, your first few days on an antifungal agent are likely to be rather 'spectacular'. But that tells you that you're killing some bugs and things should calm down soon.

Good luck!

Hi,

Great site! Just have a little comment... You provide a link to an article called "the myth of 5-htp" (or something to that effect). This article is written by a student, not a doctor or psychologist. The professor himself writes about this website: "The students each defined an area of interest, explored information about this interest on the world wide web, then examined the scientific literature and prepared a summary. Clearly, the student's reviews are not comprehensive and in each case the opinions and conclusions are their own. But in every case, I believe you will find the results interesting and informative."

I know from experience that there is little information about 5-htp on the net (most of it is from health food and vitamin stores), but I think it's a bit misleading to use this student's citation.

5-htp worked miracles for my daughter, but it had absolutely no effect on my nephew...As we all know, there isn't ONE solution to the problems of autism.

Good luck to you and your son!

Hi there, that was amazing information. I have saved this site as a favorite so I can come back and look again. We are also going through a very similar situation. We have a 4 1/2 yr old autistic boy. Aggression, oppositional defiance, behaviors..and he also opperates on a "manic" level on a daily basis. We are also doing clonidine with him. We started it at nightime for sleeping, but then started using 1/4 of a .01mg pill. First few days he was drowsy...but definately more calm. I am keeping notes as to behaviors, if the intesity is changing, etc.... He still isn't too connected right now...but after 1 week, the drowsiness has subsided and he is just more calm...but definately NOT like a zombie. Our fingers are crossed that this med works. We also tried Concerta...he tweeked out from first dose. Almost had terrets for a day, and was raged out of his mind, banging his head etc... That didn't work He seemed to have some TD side effects and was a complete zombie. I wasn't happy with that med either. Clonidine has the least side effects and I feel safe giving it to him. I'm going to post again and leave notes as to his progress.. Thank you so much for sharing your information...it helps other parents goin through the same situation. Please keep us posted!! tminor42608@yahoo.com is my email if you would like to talk more about it.

I am 40 years old. Have been on Seroquel for 9 months now. I would love to know how people sleep after having huge insomnia before seroquel as it is the most potent sleep inducer known to mankind.

I have experienced some of these side effects-
lack of motivation, extreme depression, headaches, hypotension, increased pulse, dizziness, weight gain, dry mouth, constipation, personality change, puffy gums, no interest in activities other than sleeping.

I hope this information will be useful to others,

Hello
What an informative blog lovely. My son is an adult with autism, nearly 30 years old and I am his single parent mum. On the medication side I have been through them all bar SSRI's because of the mania risks. Anti-adrenergic Clonidine is by far the safest we found in terms of paradoxical effect, on which we found neuroleptic to have by far the worst long term irreversible damage. Clonidine doesn't cover all the bases though as adulthood approaches and body mass increases accordingly. We are considering for the same reasons as you -love and care- the arachidonic acid side of things and so bi-polar avenues for the explosivity and irritability and migraine/photo sensitivity etc that go along with autism. Problem too is so little approved off label and research so poor, though Arbaclofen and the like are currently under clinical trial apparently. I got so desperate at the lack of option once I wrote to Bill Gates once with appeal for more funding to go into research. You sound like you have a really sound neurologist I envy you on that. Make sure he advises you fully on dopamine hypersensitivity potentials from neuroleptic exposure, the brain compensates for dopamine suppression by developing additional receptors in opposition. One means we found helpful for interpreting the behaviours sympathetically and so finding remedies equally so, is that you are dealing with behaviour highly susceptible and vulnerable to newtons cradle compulsion with no other means or freedom of expression. Really tough, hope this helps.

Try 5-htp with L-Thianine.
My son has PDA (which is essentially Asperger's, bipolar, OCD, and ODD wrapped into one). He has unfortunately been a bit nightmare to himself and others since birth. That is until we started giving him 5-htp with L-Thianine.. He's now a completely different happy child and I actually and so happy I have to cry.
There is enough quantitative and qualitive evidence to promote the effectiveness of these two supplements. If you are sceptical, I would suggest trying it on yourself. For the child I would recommend starting with a low dose and raising it appropriately to see if it makes any difference. I can tell you honestly that my son is finally happy and able to play independently and is not tortured and riddled by/with anxiety and panic attacks by all the little things that can and do go wrong in a day.
All the best.
