Virtually every aspect of early human development, from the brain's evolving circuitry to the child's capacity for empathy, is affected by the environments and experiences that are encountered in a cumulative fashion, beginning early in the prenatal period and extending throughout the early childhood years.

The predominant view as of 2018 is that genetic, psychological, and environmental factors all contribute to the development or progression of mental disorders. Different risk factors may be present at different ages, with risk occurring as early as during prenatal period.

Hence, it is imperative to educate mothers regarding the significance of oral health. Moreover, collaboration and support among physicians across various fields, especially among family practitioners and obstetricians, is essential in addressing the concerns for maternal oral health.Brown A. 2008. Access to Oral Health Care During the Prenatal Period: A Policy Brief.

Margaret Mahler (1965) modified Benedek's concept of symbiosis. Mahler described a parasite-host relationship between the fetus and mother during the prenatal period. During the postnatal period, the baby enters a phase called the "symbiotic envelope" where their primary task is to separate from the mother, instead of forming a relationship of attachment.

Congenital cytomegalovirus (CMV) infection refers to a condition where cytomegalovirus is transmitted in the prenatal period. CMV is a member of the virus family herpesviridae and is the most common intrauterine infection. Human cytomegalovirus is one of the vertically transmitted infections that lead to congenital abnormalities. Others include toxoplasmosis, rubella, herpes simplex, and syphilis.

The primary functions of Reelin are the regulation of corticogenesis and neuronal cell positioning in the prenatal period, but the protein also continues to play a role in adults. Reelin is found in numerous tissues and organs, and one could roughly subdivide its functional roles by the time of expression and by localisation of its action.

In the prenatal period, virilization refers to closure of the perineum, thinning and wrinkling (rugation) of the scrotum, growth of the penis, and closure of the urethral groove to the tip of the penis. In this context, masculinization is synonymous with virilization. Prenatal virilization of genetic females and undervirilization of genetic males are common causes of ambiguous genitalia and intersex conditions.
|
|
This is to be expected because female dogs retain perineal muscles whereas female rats do not have perineal muscles. As in humans, prenatal androgen plays an important role in establishing the sex differences in Onuf's nucleus of these species. If a female is exposed to excess androgen during the prenatal period, the sexual dimorphism does not occur in Onuf's nucleus.

Hypoxic-ischemic brain injury is a form of cerebral hypoxia in which oxygen cannot perfuse to cells in the brain. Lesions in the putamen and thalamus caused by this type of brain injury are primary causes of ADCP and can occur during the prenatal period and shortly after. Lesions that arise after this period typically occur as a result of injury or infections of the brain.Facts about cerebral palsy.

The children of Kauai : a longitudinal study from the prenatal period to age ten. Honolulu: University of Hawaii Press, . Werner noted that of the children who grew up in these detrimental situations, two-thirds exhibited destructive behaviors in their later teen years, such as chronic unemployment, substance abuse, and out-of-wedlock births (in case of teenage girls). However, one-third of these youngsters did not exhibit destructive behaviours.

By the time they are born, infants can recognize and have a preference for their mother's voice suggesting some prenatal development of auditory perception. Prenatal development and birth complications may also be connected to neurodevelopmental disorders, for example in schizophrenia. With the advent of cognitive neuroscience, embryology and the neuroscience of prenatal development is of increasing interest to developmental psychology research. Several environmental agents—teratogens—can cause damage during the prenatal period.

Prenatal cocaine exposure (PCE), theorized in the 1970s, occurs when a pregnant woman uses cocaine and thereby exposes her fetus to the drug. Teratogens are environmental agents, substances that can cause serious damage if exposure occurs to a fetus in the prenatal period. These can potentially cause there to be long-term effects or even be fatal to the fetus. Mothers that are using this drug while pregnant risk exposure to their unborn babies.

Isolated levocardia is congenital, and so far, there is no efficient way to prevent it. However, in the prenatal period, a prenatal evaluation is suggested. It is recommended to include determination of the situs, identification of heart anomalies, and detection of the major vessels and abdominal viscera in the prenatal evaluation. In the postnatal period, a detection of IVC interruption may be helpful and a prophylactic lifelong antibiotic should be prescribed for the neonate to treat the increase of incidence of overwhelming sepsis in congenital asplenia.

The correct function of the gastric tract and the internal health is related to the nutrition that the child or its mother receives. From the prenatal period, correct nutrition can affect the developing of the system, short bowel syndrome (the most common one), necrotizing enterocolitis, gastroschisis or omphalocele to the postnatal period with diseases such as diarrhea. One of the principal problems of a newborn is an iron deficiency, which will generate anemia. This is caused when the only food that the baby receives is maternal milk which does not fulfill the baby’s nutrition.

The bond between mothers and infants has been determined to be the core bond during the lifespan for mothers and children. At birth, mothers go through a postpartum period where they feel detached from their infant and need to create a new bond different from the one that was created during the prenatal period. The bond between mother and infant is just as important to the mother as it is to the infant. This bond can be formed after the once believed critical period of postpartum skin contact.

Recent works on the morphological changes of the mandible during development have shown that the human chin, or at least the inverted-T shaped mental region, develops during the prenatal period, but the chin does not become prominent until the early postnatal period. This later modification happens by bone remodeling processes (bone resorption and bone deposition). Coquerelle et al. show that the anteriorly positioned cervical column of the spine and forward displacement of the hyoid bone limit the anterior–posterior breadth in the oral cavity for the tongue, laryngeal, and suprahyoid musculatures.

The volume of SDN in medial preoptic area is modified by hormones, among which testosterone is proved to be of much importance. The larger volume of male SDN is correlated to the higher concentration of fetal testosterone level in males than in females. Also, there is evidence that testosterone acts during specific prenatal period to organize the development of aromatase-expressing neurons into the male-typical SDN (testosterone is transformed to estrogen by aromatase). The effect of testosterone is also shown by the influence of fetal intrauterine position on the morphology of SDN-POA.

In nearly 95% of the cases, death occurs in the neonatal period due to respiratory distress, generally related to small chest size or insufficient development of the trachea and other upper airway structures. Among survivors of CMD, the skeletal malformations change over time to include worsening scoliosis or kyphosis resulting in decreased trunk size relative to the limb length. Neurological damage is also often seen including mental retardation and deafness. Even among survivors of the prenatal period, CMD patients have shortened life spans due to lifelong respiratory issues.

Mental stress in men is associated with various complications which can affect men's health: high blood pressure and subsequent cardiovascular morbidity and mortality, cardiovascular disease, erectile dysfunction (impotence) and possibly reduced fertility (due to reduced libido and frequency of intercourse). Fathers experience stress during the time shortly before and after the time of birth (perinatal period). Stress levels tend to increase from the prenatal period up until the time of birth, and then decrease from the time of birth to the later postnatal period. Factors which contribute to stress in fathers include negative feelings about the pregnancy, role restrictions related to becoming a father, fear of childbirth, and feelings of incompetence related to infant care.

Advocates of this treatment also believe that emotional attachment of a child to a caregiver begins during the prenatal period, during which the unborn child is aware of the mother's thoughts and emotions. If the mother is distressed by the pregnancy, especially if she considers abortion, the child responds with distress and anger that continue through postnatal life. If the child is separated from the mother after birth, no matter how early this occurs, the child again feels distress and rage that will block attachment to a foster or adoptive caregiver. If the child has had a peaceful gestation, but after birth suffers pain or ungratified needs during the first year, attachment will again be blocked.

In 1983, 25 low-risk mother-infant pairs participated in a research project to predict the performance of 21 month olds on the Mental Scale of the Bayley Scale of Infant Development (BSID-1) from characteristics of infants and mothers. Questionnaires given assessed maternal responsive attitude during the prenatal period, the Neonatal Behavioral Assessment Scale was administered at 5 and 10 days, and mothers and infants were observed together at 3 months. Babies were then tested on the BSID-1 when they were 21 months of age. Mothers level of education, a responsive maternal attitude and 3-month smiling and eye contact was found to predict infant performance on the Mental Scale of the BSID-1, lending support to its validity.

At a press conference, Palmer stated that "This is not a definitive study, but just one more that furthers the association between environmental mercury and autism." Thomas Lewandowski stated in a viewpoint that "... the conclusions drawn from the analysis are questionable", and Palmer told WebMD that this type of study is not necessarily proof of a causative link between mercury and autism. Palmer has studied baby teeth for environmental toxins the children could have been exposed to during the prenatal period; this research was funded by a Suzanne and Bob Wright Trailblazer grant from Autism Speaks. He has also studied the differences in autism rates between Hispanic children and white children, and has concluded that the former are less likely to be diagnosed with the disorder than the latter.

Since the late 1980s, Perera has led studies applying molecular and imaging techniques within longitudinal cohort studies of pregnant women and their children in the U.S., Poland, and China, with the goal of identifying preventable environmental risk factors for developmental disorders, asthma, obesity, and cancer in childhood. These exposures include toxic chemicals, pesticides, and air pollution, with particular focus on the adverse effects of prenatal and early childhood exposures. This research has revealed that the prenatal period of development is especially vulnerable to toxic environmental exposures and that prenatal exposures such as air pollutants, chemicals in plastics, pesticides and flame retardants are linked to neurodevelopmental problems, obesity and/or asthma in childhood. The research also found that stress and maternal hardship can increase the harm from chemical exposures.

Because of the prevalence of birth defects due to Agent Orange in Vietnam, ultrasounds are often a means for quelling the fears of expectant mothers.[9] The Vietnamese Commission for Population, Family, and Children, gave a statement in 2004 describing their support for prenatal screening in hopes that it may promote population quality that would allow Vietnam to enter into a phase of modernization and industrialization alongside other Southeast Asian countries.[9] This focus on Vietnam's national "stock" was in part based on Japan's efforts beginning in 1945 to strengthen the physicality and quality of their population through genetics programs, encouraging scientists to have many children, and the legalization of marriage with foreigners.[9] Because of the particularly high prevalence of HIV infections in women of childbearing age world wide, in addition to Vietnam's high HIV/AIDS diagnosis rate, health counseling during the prenatal period is also focused on HIV positive expectant mothers.

The leading causes of mortality for all age groups are cerebrovascular diseases (11.6%); ischemic heart disease (9.9%); immunity disorders (7.1%); diseases of the respiratory system (6.8%); diseases of pulmonary circulation and other forms of heart disease (6.6%); endocrine and metabolic diseases (5.5%); diseases of other parts of the Digestive System (5.2%); violence (5.1%); certain condition originating in the prenatal period (4.3%); and hypertensive diseases (3.9%). The ten leading causes of morbidity for all age groups are, in decreasing order: malaria; acute respiratory infections; symptoms, signs and ill defined or unknown conditions; hypertension; accident and injuries; acute diarrhoeal disease; diabetes mellitus; worm infestation; rheumatic arthritis; and mental and nervous disorders. This morbidity profile indicates that it can be improved substantially through enhanced preventive health care, better education on health issues, more widespread access to potable water and sanitation services, and increased access to basic health care of good quality. A number of non-governmental organisations, including Health and Educational Relief for Guyana (HERG, INC) and Guyana Medical Relief (GMR, INC) are currently working to address these issues by improving healthcare access and educational infrastructure.
