Medication for Autism and ADHD
Parents of children and youth with co-occurring ASD and ADHD report high levels of use of medications. However, research on psychopharmacological treatments is limited in both number and type.
Risperidone (Risperdal) and Aripiprazole (Abilify) are the only medications approved by the FDA for use by children with autism to help reduce anger and irritability. But some other drugs can also prove beneficial.
Antipsychotics
While the interest in co-occurring ADHD and ASD symptoms has increased however, research is still limited. There are a variety of psychosocial treatment options that are available for each disorder however, few studies have evaluated effectiveness of treatments in the context of co-occurring symptoms. An improved understanding of how co-occurring psychiatric disorders develop and interplay with time will be crucial for determining both pharmacological as well as psychosocial approaches.
Many people who suffer from ASD also have co-occurring ADHD and other mental health issues like depression or anxiety. There are a variety of psychosocial treatments available for these disorders, such as cognitive behavioral therapy (CBT) and interpersonal therapy, and family therapy. These psychosocial treatments are more effective than pharmacological treatments for those who suffer from ADHD/ASD comorbidity.
For the core ASD symptoms such as inability to communicate socially and rigid thinking, non-pharmacological interventions are usually preferred. These include peer support groups as well as behavioral training. Medication can be helpful for ASD symptoms that are comorbid with ADHD like irritability and aggression, or mood dysregulation. However Atypical antipsychotics haven't been proven to reduce the fundamental ASD symptoms and the evidence for these medicines is limited at best.
The current theories suggest that symptoms of autism spectrum disorders (ASD) and ADHD are caused by alterations in neurotransmitter pathways, especially ones that involve glutamate, dopamine, and serotonin.2 This changes impact mesocorticolimbic and prefrontal cortex which is involved in the regulation of emotions and control of behavior.
These abnormalities could be caused by reduced brain activity in certain regions such as the striatum. In order to treat ADHD and ASD various medications that alter dopamine or glutamate levels are under investigation.
Several types of dopamine antagonists are being investigated for the treatment of co-occurring ADHD and ASD symptoms, including risperidone (Risperdal, Janssen Pharmaceutical Inc.; Titusville, NJ) as well as Aripiprazole (Abilify, Otsuka America Pharmaceutical Inc.; Rockville, MD) and domperidone (Motilium, Johnson & Johnson; New Brunswick, NJ). A consensus nomenclature is pending for dopamine-antagonists.
Like all medications there are a variety of people who respond the same way to antipsychotics. The most reliable data available on aripiprazole and risperidone in adults suffering from ASD and ADHD come from controlled, randomized trials. These trials utilized crossover, parallel, and withdrawal designs. In general, these drugs are more effective than placebo at reducing irritability, aggression and enhancing performance. They are also generally tolerated. However, only one-third of people who take these medicines will discover that they are effective for all or the majority of their symptoms. However, the remaining two-thirds of them will see only minor improvement.
Stimulants
Despite the fact that non-medicated treatment is generally recommended for autism, medication can be beneficial to some children and adults. Antipsychotics can reduce anxiety and self-injurious behaviours and stimulants like methylphenidate (which aids in reducing ADHD symptoms) can help improve concentration. However, they don't address core autism behaviors like repetitive and limited interests or difficulties communicating. Many adults and children with autism also have co-occurring mental health issues like depression, mood disorders or anxiety that interfere with daily functioning.
Autism can also cause anger in adults and children. It can result in anger outbursts, self-injury or difficulty with transitions or following routines. Atypical antipsychotics like risperidone (Risperdal) and aripiprazole (Abilify) are the only approved medications for treating autism-related irritation. adhd medications for adults are believed to affect the brain's dopamine system which is involved in emotions as well as decision-making.
The most commonly prescribed ADHD medication is methylphenidate such as Ritalin. It also contains mixed amphetamines salts which boost dopamine levels in the frontal brain lobes. adhd and medication suggest that these drugs are just as effective in treating patients with autism and ADHD than they are for those with pure ADHD. However, other studies indicate they may be less effective. It is important for parents to consult their physician about whether the benefits of these medications outweigh any potential negative side effects.
Some researchers believe that second line ADHD medications like atomoxetine and guanfacine, may be more effective in reducing ADHD symptoms in people with autism. These drugs are believed function by interfacing with the norepinephrine and dopamine systems, which are connected with mood and motivation.
The therapist and psychiatrist for Connor are working hard to teach him social skills and assist him in overcoming his fears. Even with these interventions hyperactivity and inattention can continue to hinder his development. So his family decided to try an ADHD medication to help him concentrate.
After three months, he's more focused in school and his daily activities. His parents can see that he's more attentive and listens to what other people say and participates in group activities. His mother says that the medication has been a lifesaver.
Benzodiazepines
The benzodiazepines are a class of drugs that slow down the central nervous system, producing sleepiness and a calm mood. These are used to treat a wide variety of ailments that include anxiety disorders, seizures, and insomnia. They target specific GABA receptors (gamma aminobutyric acid) which is a neurotransmitter, which blocks brainwaves and the communication between neurons. By opening GABA receptors and keeping them open for a longer period benzodiazepines increase inhibition and prevent excitatory neurons from becoming hyperactive. The theory is that the characteristic autism-related behaviors are caused by an imbalance between the excitatory and inhibitory neurons in the brain. This hypothesis is supported by animal models, which show that clonazepam can reverse certain autism-related behaviors in mice suffering from Dravet Syndrome, which is a type of epilepsy.
Anxiety is often a comorbid disorder in people with autism spectrum disorders. In some instances anxiety can be the reason behind an individual's aggressive or self-injurious behavior. In others it's a reaction to sensory issues that cause difficulty and trigger anxious feelings.
Antidepressants are among the treatments available. They increase the amount of norepinephrine a chemical that is found in the brain believed to improve self-esteem and cope. They also reduce reuptakes of neurotransmitters like serotonin, dopamine and norepinephrine. This reduces irritability and anxiety. Atypical antipsychotics like risperidone and aripiprazole are able to aid people suffering from autism, anger, irritability, or Tourette syndrome.
There is evidence that melatonin may increase the duration and quality of sleep in adults with ASD. There aren't any studies that have been conducted in this group. Methylphenidate can be effective in treating ADHD in children who have ASD. However it's not as effective in typical-developing kids.
Medications for autism and ADHD could be harmful when not used correctly. It's important to work with your physician to find the appropriate dosage and medication for your child or teen. Always adhere to the instructions on the label of the medication. Don't discontinue or start taking your medication abruptly, as it could be extremely risky. If you suspect you or someone you know has taken too much, seek emergency help immediately. Also, keep track of your child's height and weight frequently as well as their menstrual cycle to ensure that the medications aren't causing any unwanted negative effects.
Medication Options
Both of these conditions are common among children with autism. Treatment is often a part of the treatment program for both. The drugs that are commonly used to treat ADHD -the methylphenidate (Ritalin), amphetamines (Adderall, Vyvanse), atomoxetine (Strattera) and Guanfacine (Intuniv, Tenex) -- can be effective in treating the hyperactivity and impulsivity that are associated with autism.
Some children with autism also have severe irritability or aggression. These behaviors can be difficult for parents to manage by using only methods for managing behavior. Medications like Abilify and Risperdal can help to reduce aggression and self-injury through altering a neurotransmitter known as dopamine. These medications aren't endorsed by the FDA to be used with children with autism, but they are often prescribed "off-label" to treat specific symptoms.
It's important that parents discuss with their pediatricians if medication is appropriate for the child. A number of studies show that children who are on ADHD medications for coexisting autism may enjoy a better quality of life at home as well as at school and can make significant academic, behavioral and social progress.
Psychiatrists are trained to assist children who suffer from the symptoms of ADHD and autism. They can recommend behaviorally oriented parent training, which involves classes that are both group-based and manual. These programs help parents develop skills to reduce disruptive behavior. They can also offer psychosocial treatments that are focused on improving relationships and communication between family members.
Some families, however, opt to use medication to control their child's behavior. Parents have reported that the antipsychotics' calming effects can help reduce their child's anger, aggression as well as self-injury. They may be inclined to look into this option if other treatments do not work.
In the same way, many children with autism also suffer from a mental illness that hinders their ability to learn and function like anxiety or depression. These conditions are often co-occurring and may affect therapy effectiveness. For these children using a combination of cognitive behavioral therapy and medication can be beneficial. This approach is particularly helpful for kids who have severe autism or who do not respond to other interventions.
