In a large retrospective study in the United States, the prevalence of sexually transmitted diseases was three and a half times higher for men and women who were exposed to three to five adverse childhood experiences compared to adults who had no adverse childhood experiences Hillis et al. Steel and Herlitz determined that factors that may increase the likelihood of engaging in risky sexual behaviours include: the inability to be assertive and prevent unwanted sexual advances, feeling unworthy, and having competing needs for affection and acceptance.
These are all feelings that may occur as a consequence of child abuse and neglect. Strong associations have been made between histories of child abuse and neglect and experiences of homelessness in adulthood. A study by Herman, Susser, Struening, and Link found that the combination of lack of care and either physical or sexual abuse during childhood was strongly associated with an elevated risk of adult homelessness.
Adults who experienced a combination of a lack of care and either child physical or sexual abuse were 26 times more likely to have been homeless than those with no experiences of abuse. Higher rates of homelessness among adult survivors of abuse and neglect could be due to difficulties securing employment or experiences of domestic violence. Although evidence associating past histories of child abuse and neglect and unemployment is limited, a small body of research suggests that children and adolescents affected by abuse and neglect risk poor academic achievement at school, which may lead to difficulties finding employment in adulthood Gilbert et al.
The relationship between homelessness and adult survivors of abuse and neglect may also be connected to other adverse outcomes linked to child abuse and neglect such as substance abuse problems, mental health problems and aggressive and violent behaviour.
These consequences may make it difficult to achieve stable housing. Research investigating the effects of child abuse and neglect in adulthood is extensive. However, in most research studies it is difficult to make casual links between abuse and neglect and adverse consequences due to several limitations. Many research studies are unable to control for other environmental and social factors.
This makes it difficult to rule out influences such as socio-economic disadvantage, disability and social isolation when associating abuse and neglect with negative consequences. Most research studies on adult survivors are based on retrospective reporting of events and are therefore reliant on participants' recollection of events over long periods.
This can limit the data in that participants' recollections may have changed over time. Prospective longitudinal studies have the advantage of tracing participants with reported experiences of child abuse or neglect over several years.
Kendall-Tackett and Becker-Blease argued that there should be a mix of prospective and retrospective studies as both types of research can provide insight into the long-term consequences of child abuse and neglect.
In spite of the various limitations, research consistently indicates that adults with a history of child abuse and neglect are more likely to experience adverse outcomes. The effects of child abuse and neglect can lead to a wide range of adverse outcomes in adulthood. Adverse outcomes associated with past histories of child abuse and neglect are often inter-related. Experiencing chronic and multiple forms of maltreatment or victimisation can increase the risk of more severe and damaging adverse consequences in adulthood.

If you believe a child is in immediate danger call Police on Types of abuse and neglect Child abuse and neglect refers to any behaviour by parents, caregivers, other adults or older adolescents that is outside the norms of conduct and entails a substantial risk of causing physical or emotional harm to a child or young person.
A woman may confuse sex with love and care. This is because the abuser gave her attention and affection mainly through sexual contact. Experiences like this may also put a woman at more risk for unwanted or forced sex as an adult. Some women have learned to avoid sex or intimacy, because these experiences may bring up negative feelings and memories connected with past abuse.
If you have experienced childhood abuse, it can be overwhelming and upsetting to learn how it has affected your life. Remind yourself that you are a survivor. No matter how hard your life has been, you have found the strength to go on.
It is also important to respect the ways of coping that have allowed you to protect yourself, and to survive emotionally and physically. This same strength can be used in your work toward healing from abuse. Healing starts with learning to identify and understand what has happened to you, and how it affects your life today.

In borderline personality disorder, there is one dramatically changeable personality with an intact memory, as opposed to several distinct personalities, each with an incomplete memory. Often there is a passive, depressed primary identity who cannot remember personal history as fully as can the other more hostile, protective, or controlling identities.
People with PTSD keep re-experiencing the traumatic event in waking life or in dreams, and they actively avoid situations that might bring back memories of the trauma. For a century or more, scientists have hotly contested the relative importance of experience versus genetic endowment in the development of the brain and behavior.
We know now that our genes provide the foundation and overall structure of our brain, but that its myriad connections are sculpted and molded by experience. Based on animal studies, scientists have long believed that early deprivation or abuse may result in neurobiological abnormalities, but until recently there has been little evidence for this in humans. Then, in , A. Green and his colleagues suggested that many abused children evidenced neurological damage, even without an apparent or reported head injury.
Interestingly, although minor neurological disturbances and mild brain-wave abnormalities were more common in children who had been abused than in those who had not, Green and his colleagues did not believe that the abuse had caused them. Instead, they saw these neurological disturbances as a possible additional source of trauma, amplifying the damaging impact of an abusive environment.
In , R. Davies reported that in a sample of 22 patients involved as a child or as the younger member in an incestuous relationship, 77 percent had abnormal brain waves and 36 percent had seizures. My hypothesis is that the trauma of abuse induces a cascade of effects, including changes in hormones and neurotransmitters that mediate development of vulnerable brain regions. If we observe an association between a history of abuse and the presence of a physical abnormality, the abuse may have caused that abnormality.
To try to sort out these competing hypotheses, we conducted studies of analogous early stress in animals, where the potentially confusing elements can be carefully controlled. Observing parallel outcomes in animals and people has bolstered our belief that trauma causes brain damage, not the other way around.
Our research and that of other scientists delineates a constellation of brain abnormalities associated with childhood abuse. There are four major components:. Abnormal activity in the cerebellar vermis the middle strip between the two hemispheres of the brain , which appears to play an important role in emotional and attentional balance and regulates electrical activity within the limbic system.
People with temporal lobe epilepsy TLE —. TLE can cause hallucinations or illusions in any sense modality. Other common hallucinations are of a ringing or buzzing sound or repetitive voice, a metallic or foul taste, an unpleasant odor, or the sensation of something crawling on or under the skin.
Emotional manifestations of temporal lobe seizures usually occur suddenly, without apparent cause, and cease as abruptly as they began; they include sadness, embarrassment, anger, explosive laughter usually without feeling happy , serenity, and, quite often, fear. Without this objective EEG data, a diagnosis must be based on the frequency and severity of symptoms and the ruling out of other likely causes of those symptoms. To explore the relationship between early abuse and dysfunction of the temporolimbic system, we devised the Limbic System Checklist LSCL , which calibrates the frequency with which patients experience symptoms of temporolimbic seizures.
Compared to patients who reported no abuse, average LSCL scores were 38 percent greater in the patients with physical but not sexual abuse, and were 49 percent greater in the patients with sexual but not other physical abuse. Patients who acknowledged both physical and sexual abuse had average scores percent greater than patients reporting no abuse.
Males and females were similarly affected by abuse. As we expected, abuse before age 18, when the brain is still rapidly developing, had a greater impact on limbic irritability than later abuse. We reviewed the records of consecutive admissions to a child and adolescent psychiatric hospital to search for a link between different categories of abuse and evidence of abnormalities in brain-wave studies. In the nonabused group, left-sided EEG abnormalities were rare, whereas in the abused group they were much more common, and more than twice as common as right-sided abnormalities.
In the psychologically abused group, all the EEG abnormalities were left-sided. To dig deeper into the possibility that abuse may affect development of the left hemisphere, we looked for evidence of right-left hemispheric asymmetries in the results of neuropsychological testing. This corroborated our hypothesis that abuse is associated with an increased prevalence of left-sided EEG abnormalities and of left-hemisphere defects in neuropsychological testing.
Patients and volunteers were between 6 and 15 years of age, right-handed, and with no history of neurological disorders or abnormal intelligence. Measuring EEG coherence indicated that the left cortex of the healthy controls was more developed than the right cortex, which is consistent with what is known about the anatomy of the dominant hemisphere. The abused patients, however, were notably more developed in the right than the left cortex, even though all were right-handed.
The right hemisphere of abused patients had developed as much as the right hemisphere of the controls, but their left hemispheres lagged substantially, as though arrested in their development. It extended throughout the entire left hemisphere, but the temporal regions were most affected. The hippocampus, located in the temporal lobe, is involved in memory and emotion. Developing very gradually, the hippocampus is one of the few parts of the brain that continues to produce new cells after birth.
Cells in the hippocampus have an unusually large number of receptors that respond to the stress hormone cortisol. Since animal studies show that exposure to high levels of stress hormones like cortisol has toxic effects on the developing hippocampus, this brain region may be adversely affected by severe stress in childhood. Douglas Bremner and his colleagues at Yale Medical School compared magnetic resonance imaging MRI scans of 17 adult survivors of childhood physical or sexual abuse, all of whom had PTSD, with 17 healthy subjects matched for age, sex, race, handedness, years of education, body size, and years of alcohol abuse.
Not surprisingly, given the role of the hippocampus in memory, these patients also had lower verbal memory scores than the nonabused group.
Murray Stein and his colleagues also found left hippocampal abnormalities in women who had been sexually abused as children. Fifteen of the 21 sexually abused women had PTSD; 15 had a dissociative disorder. They suffered a reduction in the size of the left hippocampus proportionate to the severity of their symptoms. The left hemisphere is specialized for perceiving and expressing language, the right hemisphere for processing spatial information and also for processing and expressing negative emotions.
We wondered, then, whether abused children might store their disturbing childhood memories in the right hemisphere, and whether recollecting these memories would activate the right hemisphere more than it is activated in those without such a history. To test this hypothesis, we measured hemispheric activity in adults during recall of a neutral memory, then during recall of an upsetting early memory.
Those in the control group had a more integrated bilateral response. Furthermore, in boys, neglect exerted a far greater effect than any other type of maltreatment; physical and sexual abuse exerted relatively minimal effects. In girls, however, sexual abuse was a more powerful factor, associated with a major reduction in size of the middle portions of the corpus collosum. Building on this work, other scientists discovered that these consequences were less severe if the surrogate mother swung from side to side, a type of movement that may be conveyed to the cerebellum, particularly the part called the cerebellar vermis, located at the back of the brain, just above the brain stem.
Like the hippocampus, this part of the brain develops gradually and continues to create new neurons after birth. It also has an extraordinarily high density of receptors for stress hormone, so exposure to such hormones can markedly affect its development.
We have gone from thinking of the entire cerebellum as involved only in motor coordination to believing that it plays an important role in regulating attention and emotion. The cerebellar vermis, in particular, seems to be involved in the control of epilepsy or limbic activation.
Testing this hypothesis, we found that the vermis seems to become activated to control— and quell—electrical irritability in the limbic system. It appears less able to do this in people who have been abused. If, indeed, the vermis is important not only for postural, attentional, and emotional balance, but in compensating for and regulating emotional instability, this latter capacity may be impaired by early trauma. By contrast, stimulation of the vermis through exercise, rocking, and movement may exert additional calming effects, helping to develop the vermis.
By contrast, long isolation produces stress that has a deleterious effect on brain and behavior development. If we assume that lots of attention, licking, and grooming are the natural state of affairs and that lower levels of attention are a form of neglect, we can use this model to explore some of the biological consequences of neglect or abuse in children.
Low rates of maternal attention decrease the production of thyroid hormone by the rat pups. This, in turn, decreases serotonin in the hippocampus and affects the development of receptors for the stress hormone glucocorticoid. Since corticosterone, one of our primary stress hormones, is kept in check by a complicated feedback mechanism that depends on these same stress hormone receptors, their inadequate development increases the risk of an excessive stress hormone response to adversity.
For this and certain other reasons, lack of maternal attention predisposes the animals to have a heightened level of fear and a heightened adrenaline response. These consequences seem consistent with inadequate development of the corpus collosum, which is a highly myelinated structure, and abnormal development of the hippocampus and cerebellum.
