Approximately 2500 years ago, the great physician-scientist Hippocrates described a condition that is quite compatible with attention-deficit/hyperactivity disorder (ADHD). He described the patient as having “quickened responses to sensory experience, but also less tenaciousness because the soul moves on quickly to the next impression,” and attributed these symptoms to an “overbalance of fire over water.” His treatment recommendation was “barley rather than wheat bread, fish rather than meat, watery drinks, and many natural and diverse physical activities.”24 Hippocrate's formulation was scientific avant-garde for his time, because he hypothesized a disorder that was due to an imbalance of physical elements, fire and water, rather than to divine and supernatural forces. His treatment approach, however, was mainstream classical Greek and rested on the “dietetic” system of maintenance and restoration of mind and body integrity through specific physical, mental, and musical exercises and diet. Hippocrate's management plan contained most of what we currently would consider to be alternative treatments. His dietary prescription interestingly anticipated modern theories of the benefit of a gluten-free diet and essential fatty acids in brain-behavior functions.

Since the publication of the article by Eisenberg et al16 about unconventional medicine usage in the United States, alternative medicine has come out of the closet and has become a significant focus of discussion and funded research within the orthodox medical community. Alternative medicine is a somewhat ambiguous term, spanning a broad spectrum from nonwestern medical traditions to the experimental application of molecular biology research, with many different shades in between. Alternative also implies different disease conceptualization, diagnostic techniques, and treatment expectations in addition to different treatment methods. Alternative approaches often lack scientific validation, sometimes taking isolated facts or findings out of context and turning them into fads. Complementary and alternative treatments are not at all unique in this aspect, however, because only approximately 15% of mainstream medical treatment is evidence based.17 Fortunately, alternative medicine is no longer dogmatically exclusive of mainstream approaches. Proponents often recommend combining mainstream and nonmainstream modalities into a holistic, complementary, and integrative treatment for complex medical conditions.

Alternative treatments often mirror the scientific uncertainty and complexity of the conditions for which they are intended. ADHD is such a complex condition that has diverse symptoms and no clearly identifiable etiology. Stimulant medications are generally recognized as the treatment of choice for ADHD. Because of their effectiveness, relative safety, and enormous frequency of use, stimulant medications have achieved the status of a gold standard against which any treatment for ADHD, mainstream or alternative, is held.

Despite this, alternatives to stimulant medications are sought for many reasons. Many parents turn to alternative treatments because they are concerned about the risk of giving their child a powerful psychoactive medication over an indeterminable and often prolonged period of time. This concern is fueled by negative publicity in the lay press regarding stimulants. To some parents, stimulants represent a symptomatic quick fix rather than a long-term solution. Other parents may seek a more natural approach to treatment or greater involvement in the therapeutic process. Finally, nonpharmacologic alternatives may be sought when stimulants are ineffective, produce unacceptable side effects, or are contraindicated because of a comorbid condition.

Publications on alternative treatments for ADHD are sparse in the peer-reviewed literature but abound in the popular press and on the Internet. A plethora of websites provide information ranging from well-researched articles to pure opinion. Parents often have ready access to these resources and may approach their health care provider for more information regarding alternative treatment options. Consequently, the practitioner must be prepared to provide accurate information and answer questions.

This article strives to give a general overview of those alternative approaches that are commonly discussed in the scientific and lay literature. The intent is to illustrate the diversity of these approaches and not to advocate or endorse any of the discussed treatments as the solution to the problem of ADHD.

DIETARY MANAGEMENT

Dietary management of ADHD remains a controversial topic that has become more complicated rather than simplified over time. The current research into the interaction of diet and behavior focuses primarily on the roles that nutritional deficiency, malnutrition, metabolic disturbances, food allergies, and food sensitivities play in the biochemical basis of behavior. Diet and nutrition can affect general mood and behavior and have wide implications for neurodevelopmental and neurodegenerative

THE ROLE OF ELIMINATION DIETS IN ADHD

Based on the research of the last 20 years, it is difficult to dismiss summarily the findings that a subgroup of children with ADHD responds favorably to individualized elimination diets. A role for behavioral food sensitivity has been defined more clearly. Several specific conclusions can be drawn from this newer research: (1) behavioral improvement is more likely with appropriate elimination diets in individuals with atopic histories, family history of migraine, and a family history of food

SUGAR

The research on sugar is much clearer in disproving its role in ADHD. The preference for the taste of sugar is hardwired in the brain, which depends totally on glucose as its metabolic substrate. This is reinforced by the social role of sugar as treats, rewards, and consolation. Children with ADHD often have conspicuous sugar cravings. This contributes to the tenacious perception that sugar and candy intake can cause hyperactive behavior, despite ample evidence to the contrary.29

ASPARTAME

Aspartame appeared on the market as an artificial sweetener in 1981 and was used as the placebo in several of the aforementioned sugar studies. Aspartame consists of the neurotransmitter precursor aminoacids aspartic acid and phenylalanine. This raised concern that aspartame could precipitate seizures or ADHD behaviors in susceptible individuals. However, no independent neurologic, metabolic, or behavioral-cognitive effects related to aspartame have been found in studies of persons with seizure

THE YEAST CONNECTION

Dr. William Crook, a practicing allergist and pediatrician, noted a 75% success rate in reducing hyperactive behavior in his patients with ADHD using individualized elimination diets.12 Based on prior research on the immunologic effects of candida infection, Crook maintained that prolonged or frequent antibiotic treatment results in chronic candidiasis and candida toxin production. This, in turn, is responsible for a variety of metabolic and behavioral disturbances, including hyperactivity,

DIETARY SUPPLEMENTS AND DIETARY DEFICIENCY

An adequate diet is clearly a necessary requirement for growth and development and is particularly critical in the first few years of life during the periods of most active brain growth and synaptic formation. Protein-calorie deprivation during this time has been associated with later cognitive, learning, and behavioral dysfunction.19 Adequate protein-calorie supplementation during infancy and early childhood improved cognitive, social, and adaptive parameters at 6 to 8 years compared with

ESSENTIAL FATTY ACIDS

The essential fatty acids (EFAs) linoleic acid and linolenic acid are essential to brain development and neuronal functioning. Interest in a relationship between EFAs and ADHD first arose when epidemiologic studies in Britain revealed a higher rate of nonspecific physical symptoms typical of EFA deficiency (increased thirst and atopic conditions) in children with hyperactivity.36 In a carefully conducted study, Stevens et al53 subsequently found significantly lower plasma levels of EFAs in

ROLE OF NUTRITIONAL SUPPLEMENTATION IN THE TREATMENT OF ADHD

Marginal deficiency of many micronutrients has been identified in a significant portion of the average American population. Children with ADHD may be at a somewhat increased risk because their eating habits are often erratic and because they may experience appetite suppression secondary to treatment with stimulant medications. There is inconsistent evidence that specific micronutrient deficiency may enhance ADHD symptoms and may decrease response to pharmacotherapy. If significant dietary

NOOTROPICS

The term nootropic is derived from the Greek words noos (mind) and tropos (turn) and refers to substances that reportedly enhance mental competence and stave off aging. They are classified as cerebral metabolic enhancers because they appear to be effective by potentiating existing metabolic activity (through neurotransmitter and ion channel function) rather than possessing any direct activity of their own. This is also believed to be the explanation for their low toxicity and absence of

ANTIOXIDANTS AND HERBS

Most of the agents in this category have been used in folk and traditional medicine for cognitive improvement and as antiaging remedies for centuries, but it is only recently that their pharmacologic properties are undergoing scientific evaluation. None has been studied systematically in ADHD, and their effectiveness as adjunctive treatment in standard ADHD treatment is not known.

Pycnogenol, a bioflavinoid antioxidant extracted from pinebark,11 has been used in Europe for some time in the

VISION THERAPY AND OCULOVESTIBULAR TREATMENT

Impairment of visual acuity, oculomotor function, and visuospatial perception has been implicated in the etiology of dyslexia and secondary attentional problems. There is no support for this hypothesis, however, or for the claims that specific ocular exercises or colored lenses can alleviate dyslexia or ADHD.31 Anecdotal reports of remarkable improvement of ADHD symptoms when prismatic lenses are introduced to correct alleged dysfunction of the oculovestibular-cerebellar system also have no

HOMEOPATHY

Homeopathy is a therapeutic system developed 200 years ago by Fr. Hahnemann that runs completely counter to conventional scientific principles. It is based on the concept that illness results from a disorder of “vital energies” and that the purpose of treatment is to restore these energies. Treatment consists of extreme dilutions of plant, animal, or mineral extracts that are highly individualized to the symptoms of the patient. There are several randomized, double-blind, placebo-controlled

AUDITORY STIMULATION: TOMATIS METHOD

There is a growing volume of academic research and publications in the popular press regarding the role of music in emotional and cognitive processes and its specific applications in medicine and education. An interesting controlled study by Abikoff et al1 showed that boys with ADHD improved their ability to solve arithmetic problems when they listened to their favorite music. This was interpreted as the effect of increased arousal with a highly salient stimulus. Otherwise there has been little

BIOFEEDBACK HYPNOTHERAPY

Hypnotherapy, self-hypnosis, guided imagery, biofeedback, and relaxation training are related techniques whose goal is to facilitate physiologic and psychological self-regulation of the patient. The mechanisms of action are not known, but effectiveness can be demonstrated by changes in physiologic parameters. These techniques are successful in many common pediatric conditions ranging from eczema to migraines. Children's ready acceptance of suggestion and the ease of mobilizing physiologic

SUMMARY

ADHD is a syndrome that can be treated effectively, safely, and economically with stimulant medications. There is no equal alternative to these agents in short-term treatment of ADHD symptoms. However, many families seek alternatives to stimulants and other drug treatments for a variety of reasons. Alternative approaches reflect the complexity and heterogeneity of the disorder by being equally manifold, complex, and often obscure in their modus operandi.
