Cognitive-behavioral disorders affect development and behavior, especially during early childhood. Early detection, observation by parents and pediatricians, and targeted interventions based on the cause help optimize learning and minimize long-term effects.
There are two basic aspects in the prevention, detection, and treatment of cognitive-behavioral disorders: observation by the parents and observation by the child’s pediatrician. This highlights the importance of routine visits to the pediatrician.
During the first year of life, stimulation through play and singing is fundamental. The brain’s plasticity for learning during the first year is higher than at any other stage of life, and the brain’s weight grows exponentially. Stimuli are essential; both smiling and passive limb mobilization naturally occur through play. Observing the child is also important to see which areas need more work, such as teaching them to roll over, crawl, or walk. In case of doubt or detection of a significant alteration, a multidisciplinary approach is necessary to establish the diagnosis and appropriate treatment as early as possible.
The treatment of cognitive-behavioral disorders depends on the specific condition detected.
Human genome ultra-sequencing now allows the detection of hundreds of genetic alterations from a small blood sample, from which genetic information is extracted. There are databases in all developed countries that work in a network, sharing information to compile sporadic cases worldwide for joint research into how these alterations affect behavior or learning in individuals.
Similarly, biochemical studies of the body’s metabolic pathways are increasingly comprehensive, allowing the design of specific drugs for each situation.
A treatment shift currently under development involves moving from the pill to the cell, aiming to work directly on the affected cell to modify its behavior. This approach is still very preliminary but is a field that is certain to see significant development in the future.
Immunological diseases can impair the body’s defense system or cause an inappropriate immune response. Proper medical follow-up, adherence to treatment, and healthy lifestyle habits are essential to prevent infections, manage symptoms, and improve quality of life.
A person’s immune status depends on their overall health: proper nutrition and avoiding exposure to tobacco smoke and chemicals whenever possible. In early childhood, the vaccines and immunizations recommended in the vaccination schedule help build a competent immune system.
In primary immunodeficiencies, early detection is important, usually indicated by the presence of frequent infectious diseases. Secondary immunodeficiencies occur during treatment for neoplasms or in transplant patients who must take lifelong immunosuppressive medication.
In autoimmune diseases, it is essential to follow the prescribed medication, often for life, and to avoid excessive cold and sun exposure, which can trigger disease manifestations. To maintain the functionality of joints and muscles, following specific rehabilitation guidelines is important.
In immune deficiency, administering immunoglobulins (blood proteins responsible for our defense) can play an important role. When the deficiency affects immune cells, immunoglobulins are not effective; in such cases, antibiotics can prevent or reduce infections.
In diseases caused by excessive or poorly regulated immune responses, anti-inflammatory drugs and medications that modulate immunity are used, such as corticosteroids and biologics, which block specific inflammatory pathways. Other drugs may also have beneficial effects through less well-understood mechanisms, such as some medications used to treat malaria.
Cognitive-behavioral disorders affect the development of children’s mental, emotional, and behavioral abilities. Early observation by families and pediatricians, along with proper stimulation and a multidisciplinary approach, allows for timely detection and treatment.

Cognitive-behavioral disorders are conditions that affect thinking, behavior, and learning, and their treatment depends on the underlying cause. Early detection is key, as in some cases specific diets or medications can help improve the disorder.

A new treatment approach, currently under development, is the shift from pills to cells as therapy—working directly on the affected cell to modify its behavior. This approach is still very preliminary, but it is a field that will undoubtedly see significant development in the future.
The neurosensory development of children is a complex process that begins during intrauterine life and continues from the neonatal stage throughout childhood and into adolescence. All disorders or dysfunctions related to learning or behavior are grouped under cognitive-behavioral disorders.
Learning is a constant part of human behavior throughout life, but the quantity and quality of knowledge acquired during the first year of life is far greater—or at least comparable—to that acquired over the rest of a lifetime. The human brain increases in weight by one gram per day during the first year, followed by the formation of neuronal connections and networks that enable social smiling at one month of age, recognition of unfamiliar people at seven months, and learning to refuse to release objects around one year of age. In parallel, motor development progresses, allowing children to walk between 12 and 16 months. As development continues, cognitive (learning) and behavioral (approach–avoidance) growth intertwine, along with social interactions with parents and siblings. Many times, it is the parents—and sometimes pediatricians—who first notice that a child seems “different” or shows behaviors that draw attention.
The spectrum of cognitive-behavioral disorders is very broad, as are their symptoms. In general, symptoms include not achieving cognitive or behavioral milestones within the age range considered normal. For example, not exhibiting a social smile by the second month of life or not recognizing strangers by twelve months. Cognitive-behavioral disorders often form part of a broader condition, frequently with a genetic basis that may also affect other organs.
The incidence of cognitive-behavioral disorders is estimated to be between 1% and 3% of all children.
Parents are often the first to notice atypical signs in development or behavior, sometimes by comparing with siblings. During routine visits, the pediatrician evaluates age-appropriate developmental skills. If further assessment is needed, pediatric neurologists and geneticists can provide a more precise diagnosis. Diagnostic tests for these disorders always include a physical examination, genetic analysis, and laboratory tests that evaluate for metabolic diseases. Neuroimaging studies may also be helpful.
Treatment depends on the cause of the cognitive-behavioral developmental disorder. If the cause is metabolic, effective and sometimes curative treatments may exist. If the cause is genetic, it is possible to predict the course of the condition and recommend supportive educational strategies, although fully effective treatments are not yet available.
The physical examination helps determine whether the child is reaching developmental milestones appropriate for their age.
Genetic tests detect whether there is an alteration in the patient’s genes that could explain the observed anomaly.
Laboratory tests—typically using blood or urine—help confirm or rule out abnormalities in the body’s normal metabolic pathways.
Pediatric neurological examination, imaging studies, metabolic laboratory tests, genetic studies based on sequencing or ultra-sequencing, and evaluation by Child Psychiatry (Pediatric Psychiatry).
If there is a family history of cognitive-behavioral disorders, genetic counseling prior to pregnancy may be useful. The neurosensory development of children is a complex process that begins during intrauterine life and continues from the neonatal stage through childhood and adolescence. Adequate monitoring during pregnancy and childbirth is also essential to help prevent these types of disorders.
