Most head injuries are of a benign nature and require no treatment beyond analgesics and close monitoring for potential complications such as intracranial bleeding. If the brain has been severely damaged by trauma, neurosurgical evaluation may be useful. Treatments may involve controlling elevated intracranial pressure. This can include sedation, paralytics, cerebrospinal fluid diversion. Second line alternatives include decompressive craniectomy (Jagannathan et al. found a net 65% favorable outcomes rate in pediatric patients), barbiturate coma, hypertonic saline and hypothermia. Although all of these methods have potential benefits, there has been no randomized study that has shown unequivocal benefit.
Clinicians will often consult clinical decision support rules such as the Canadian CT Head Rule or the New Orleans/Charity Head injury/Trauma Rule to decide if the patient needs further imaging studies or observation only. Rules like these are usually studied in depth by multiple research groups with large patient cohorts to ensure accuracy given the risk of adverse events in this area.
DAI currently lacks a specific treatment beyond what is done for any type of head injury, including stabilizing the patient and trying to limit increases in intracranial pressure (ICP).
Diffuse axonal injury (DAI) is a brain injury in which damage in the form of extensive lesions in white matter tracts occurs over a widespread area. DAI is one of the most common and devastating types of traumatic brain injury, and is a major cause of unconsciousness and persistent vegetative state after severe head trauma. It occurs in about half of all cases of severe head trauma and may be the primary damage that occurs in concussion. The outcome is frequently coma, with over 90% of patients with severe DAI never regaining consciousness. Those who do wake up often remain significantly impaired.
DAI can occur in every degree of severity from very mild or moderate to very severe. Concussion may be a milder type of diffuse axonal injury.
In children with uncomplicated minor head injuries the risk of intra cranial bleeding over the next year is rare at 2 cases per 1 million. In some cases transient neurological disturbances may occur, lasting minutes to hours. Malignant post traumatic cerebral swelling can develop unexpectedly in stable patients after an injury, as can post traumatic seizures. Recovery in children with neurologic deficits will vary. Children with neurologic deficits who improve daily are more likely to recover, while those who are vegetative for months are less likely to improve. Most patients without deficits have full recovery. However, persons who sustain head trauma resulting in unconsciousness for an hour or more have twice the risk of developing Alzheimer's disease later in life.
Head injury may be associated with a neck injury. Bruises on the back or neck, neck pain, or pain radiating to the arms are signs of cervical spine injury and merit spinal immobilization via application of a cervical collar and possibly a long board.If the neurological exam is normal this is reassuring. Reassessment is needed if there is a worsening headache, seizure, one sided weakness, or has persistent vomiting.
To combat overuse of Head CT Scans yielding negative intracranial hemorrhage, which unnecessarily expose patients to radiation and increase time in the hospital and cost of the visit, multiple clinical decision support rules have been developed to help clinicians weigh the option to scan a patient with a head injury. Among these are the Canadian Head CT rule, the PECARN Head Injury/Trauma Algorithm, and the New Orleans/Charity Head Injury/Trauma Rule all help clinicians make these decisions using easily obtained information and noninvasive practices.
For most balance and gait disorders, some form of displacement exercise is thought helpful (for example walking, jogging, or bicycling but not on a treadmill or stationary bicycle). This has not been well-studied in MdDS. Medications that suppress the nerves and brain circuits involved in balance (for example, the benzodiazepine clonazepam) have been noted to help and can lower symptoms, but it is not a cure. It is not known whether medication that suppress symptoms prolongs symptom duration or not. Vestibular therapy has not proved to be effective in treating MdDS.
Additional research is being undertaken into the neurological nature of this syndrome through imaging studies. The disorder remains incurable and permanent if the symptoms do not remit in a short period of time.
At least one clinical trial on readaptation of the vestibulo-ocular reflex undertaken by Dr Mingjia Dai from Mount Sinai Hospital in New York City has produced results for a significant percentage of patients who have participated in the program.
Dai has developed an intervention that provided improvement in symptoms for 70% of the patients in the clinical trial phase. The protocol involves a physical manipulation of the patient intended to readapt the vestibulo-ocular reflex. While the program is no longer in the research phase, Dai continues to accept patients. According to Dai, "success" is measured as a 50% reduction of symptoms.
Recent research reveals a very small percentage of MdDS cases may be related to optokinetic nystagmus (OKN).
The terms attachment disorder, attachment problems, and attachment therapy, although increasingly used, have no clear, specific, or consensus definitions. However, the terms and therapies often are applied to children who are maltreated, particularly those in the foster care, kinship care, or adoption systems, and related populations such as children adopted internationally from orphanages.
Outside the mainstream programs is a form of treatment generally known as attachment therapy, a subset of techniques (and accompanying novel diagnosis) for supposed attachment disorders including RAD. These "attachment disorders" use diagnostic criteria or symptom lists different to criteria under ICD-10 or DSM-IV-TR, or to attachment behaviors. Sufferers of "attachment disorder" are said to lack empathy and remorse.
Treatments of this pseudoscientific disorder are called "Attachment therapy". In general, these therapies are aimed at adopted or fostered children with a view to creating attachment in these children to their new caregivers. The theoretical base is broadly a combination of regression and catharsis, accompanied by parenting methods which emphasize obedience and parental control. There is considerable criticism of this form of treatment and diagnosis as it is largely unvalidated and has developed outside the scientific mainstream. There is little or no evidence base and techniques vary from non-coercive therapeutic work to more extreme forms of physical, confrontational and coercive techniques, of which the best known are holding therapy, rebirthing, rage-reduction and the Evergreen model. These forms of the therapy may well involve physical restraint, the deliberate provocation of rage and anger in the child by physical and verbal means including deep tissue massage, aversive tickling, enforced eye contact and verbal confrontation, and being pushed to revisit earlier trauma. Critics maintain that these therapies are not within the attachment paradigm, are potentially abusive, and are to attachment theory. The APSAC Taskforce Report of 2006 notes that many of these therapies concentrate on changing the child rather than the caregiver. Children may be described as "RADs", "Radkids" or "Radishes" and dire predictions may be made as to their supposedly violent futures if they are not treated with attachment therapy. The Mayo Clinic, a well known U.S. non-profit medical practice and medical research group, cautions against consulting with mental health providers who promote these types of methods and offer evidence to support their techniques; to date, this evidence base is not published within reputable medical or mental health journals.
Assessing the child's safety is an essential first step that determines whether future intervention can take place in the family unit or whether the child should be removed to a safe situation. Interventions may include psychosocial support services for the family unit (including financial or domestic aid, housing and social work support), psychotherapeutic interventions (including treating parents for mental illness, family therapy, individual therapy), education (including training in basic parenting skills and child development), and monitoring of the child's safety within the family environment
In 2005 the American Academy of Child and Adolescent Psychiatry laid down guidelines (devised by N.W. Boris and C.H. Zeanah) based on its published parameters for the diagnosis and treatment of RAD. Recommendations in the guidelines include the following:
1. "The most important intervention for young children diagnosed with reactive attachment disorder and who lack an attachment to a discriminated caregiver is for the clinician to advocate for providing the child with an emotionally available attachment figure."
2. "Although the diagnosis of reactive attachment disorder is based on symptoms displayed by the child, assessing the caregiver's attitudes toward and perceptions about the child is important for treatment selection."
3. "Children with reactive attachment disorder are presumed to have grossly disturbed internal models for relating to others. After ensuring that the child is in a safe and stable placement, effective attachment treatment must focus on creating positive interactions with caregivers."
4. "Children who meet criteria for reactive attachment disorder and who display aggressive and oppositional behavior require adjunctive (additional) treatments."
Mainstream prevention programs and treatment approaches for attachment difficulties or disorders for infants and younger children are based on attachment theory and concentrate on increasing the responsiveness and sensitivity of the caregiver, or if that is not possible, placing the child with a different caregiver. These approaches are mostly in the process of being evaluated. The programs invariably include a detailed assessment of the attachment status or caregiving responses of the adult caregiver as attachment is a two-way process involving attachment behavior and caregiver response. Some of these treatment or prevention programs are specifically aimed at foster carers rather than parents, as the attachment behaviors of infants or children with attachment difficulties often do not elicit appropriate caregiver responses. Approaches include "Watch, wait and wonder," manipulation of sensitive responsiveness, modified "Interaction Guidance", "Clinician-Assisted Videofeedback Exposure Sessions (CAVES)", "Preschool Parent Psychotherapy", "Circle of Security", "Attachment and Biobehavioral Catch-up" (ABC), the New Orleans Intervention, and parent–child psychotherapy. Other treatment methods include Developmental, Individual-difference, and Relationship-based therapy (DIR, also referred to as Floor Time) by Stanley Greenspan, although DIR is primarily directed to treatment of pervasive developmental disorders.
The relevance of these approaches to intervention with fostered and adopted children with RAD or older children with significant histories of maltreatment is unclear.
There are a variety of mainstream prevention programs and treatment approaches for attachment disorder, attachment problems and moods or behaviors considered to be potential problems within the context of attachment theory. All such approaches for infants and younger children concentrate on increasing the responsiveness and sensitivity of the caregiver, or if that is not possible, changing the caregiver. Such approaches include 'Watch, wait and wonder,' manipulation of sensitive responsiveness, modified 'Interaction Guidance,'. 'Preschool Parent Psychotherapy,'. Circle of Security', Attachment and Biobehavioral Catch-up (ABC), the New Orleans Intervention, and Parent-Child psychotherapy. Other known treatment methods include Developmental, Individual-difference, Relationship-based therapy (DIR) (also referred to as "Floor Time") by Stanley Greenspan, although DIR is primarily directed to treatment of pervasive developmental disorders Some of these approaches, such as that suggested by Dozier, consider the attachment status of the adult caregiver to play an important role in the development of the emotional connection between adult and child. This includes foster parents, as children with poor attachment experiences often do not elicit appropriate caregiver responses from their attachment behaviors despite 'normative' care.
Treatment for reactive attachment disorder for children usually involves a mix of therapy, counseling, and parenting education. These must be designed to make sure the child has a safe environment to live in and to develop positive interactions with caregivers and improves their relationships with their peers.
Medication can be used as a way to treat similar conditions, like depression, anxiety, or hyperactivity; however, there is no quick fix for treating reactive attachment disorder. A pediatrician may recommend a treatment plan. For example, a mix of family therapy, individual psychological counseling, play therapy, special education services and parenting skills classes.
Attachment disorder is a broad term intended to describe disorders of mood, behavior, and social relationships arising from a failure to form normal attachments to primary care giving figures in early childhood. Such a failure would result from unusual early experiences of neglect, abuse, abrupt separation from caregivers between 6 months and three years of age, frequent change or excessive numbers of caregivers, or lack of caregiver responsiveness to child communicative efforts resulting in a lack of basic trust. A problematic history of social relationships occurring after about age three may be distressing to a child, but does not result in attachment disorder.
The term attachment disorder is used to describe emotional and behavioral problems of young children, and also applied to school-age children, teenagers and adults. The specific difficulties implied depend on the age of the individual being assessed, and a child's attachment-related behaviors may be very different with one familiar adult than with another, suggesting that the disorder is within the relationship and interactions of the two people rather than an aspect of one or the other personality. No list of symptoms can legitimately be presented but generally the term attachment disorder refers to the absence or distortion of age appropriate social behaviors with adults. For example, in a toddler, attachment-disordered behavior could include a failure to stay near familiar adults in a strange environment or to be comforted by contact with a familiar person, whereas in a six-year-old attachment-disordered behavior might involve excessive friendliness and inappropriate approaches to strangers.
There are currently two main areas of theory and practice relating to the definition and diagnosis of attachment disorder, and considerable discussion about a broader definition altogether. The first main area is based on scientific enquiry, is found in academic journals and books and pays close attention to attachment theory. It is described in ICD-10 as reactive attachment disorder, or "RAD" for the inhibited form, and disinhibited attachment disorder, or "DAD" for the disinhibited form. In DSM-IV-TR both comparable inhibited and disinhibited types are called reactive attachment disorder or "RAD".
The second area is controversial and considered pseudoscientific. It is found in clinical practice, on websites and in books and publications, but has little or no evidence base. It makes controversial claims relating to a basis in attachment theory. The use of these controversial diagnoses of attachment disorder is linked to the use of pseudoscientific attachment therapies to treat them.
Some authors have suggested that attachment, as an aspect of emotional development, is better assessed along a spectrum than considered to fall into two non-overlapping categories. This spectrum would have at one end the characteristics called secure attachment; midway along the range of disturbance would be insecure or other undesirable attachment styles; at the other extreme would be
non-attachment. Agreement has not yet been reached with respect to diagnostic criteria.
Finally, the term is also sometimes used to cover difficulties arising in relation to various attachment styles which may not be disorders in the clinical sense.
In Chinese alchemy, elixir poisoning refers to the toxic effects from elixirs of immortality that contained metals and minerals such as mercury and arsenic. The official "Twenty-Four Histories" record numerous Chinese emperors, nobles, and officials who ironically died from taking elixirs in order to prolong their lifespans. The first emperor to die from elixir poisoning was likely Qin Shi Huang (d. 210 BCE) and the last was Yongzheng (d. 1735). Despite common knowledge that immortality potions could be deadly, fangshi and Daoist alchemists continued the elixir-making practice for two millennia.
Needham and Lu's third justification for taking poisonous elixirs is a drug-induced "temporary death", possibly a trance or coma. In the classic legend (above) about Wei Boyang drinking an elixir of immortality, he appears to die, subsequently revives, and takes more elixir to achieve immortality.
The "Baopuzi" describes a Five Mineral-based multicolored Ninefold Radiance Elixir that can bring a corpse back to life: "If you wish to raise a body that has not been dead for fully three days, bathe the corpse with a solution of one spatula of the blue elixir, open its mouth, and insert another spatula full; it will revive immediately." (tr. Ware 1966:82).
A Tang Daoist text prescribes taking an elixir in doses half the size of a millet grain, but adds, "If one is sincerely determined, and dares to take a whole spatula-full all at once, one will temporarily die ["zànsǐ" 暫死] for half a day or so, and then be restored to life like someone waking from sleep. This however is perilous in the extreme." (tr. Needham and Lu 1974: 295).
The distinction between Hua () and Yi (), also known as Sino–barbarian dichotomy, is an ancient Chinese concept that differentiated a culturally defined "China" (called Hua, Huaxia 華夏, or Xia 夏) from cultural or ethnic outsiders (Yi "barbarians"). Although Yi is often translated as "barbarian", other translations of this term in English include "foreigners",
"ordinary others" "wild tribes", and "uncivilized tribes."
The Hua–Yi distinction asserted Chinese superiority, but implied that outsiders could become "Hua" by adopting Chinese values and customs.
Ancient China was composed of a group of states that arose in the Yellow River valley. According to historian Li Feng, during the Zhou dynasty (ca. 1041–771 BCE), the contrast between the 'Chinese' Zhou and the 'non-Chinese' Xirong or Dongyi was "more political than cultural or ethnic". Lothar von Falkenhausen argues that the perceived contrast between "Chinese" and "Barbarians" was accentuated during the Eastern Zhou period (770–256 BCE), when adherence to Zhou rituals became increasingly recognized as a "barometer of civilization."; a meter for sophistication and cultural refinement. It is widely agreed by historians that the distinction between the Hua and the Yi emerged during that period.
Gideon Shelach claimed that Chinese texts tended to overstate the distinction between the Chinese and their northern neighbors, ignoring many intergroup similarities. He doubted the existence of the Hua–Yi distinction. Nicola di Cosmo doubted the existence of a strong demarcation between the "Zhou Universe" and "a discrete, 'barbarian', non-Zhou universe" and claimed that Chinese historian, Sima Qian's popularized this concept, writing of the "chasm that had always existed between China – the Hua-Hsia [Huaxia] people – and the various alien groups inhabiting the north."
The conclusion of the Warring States period brought the first unified Chinese state-established by the Qin dynasty in 221 BCE-who established the imperial system and forcibly standardized the traditional Chinese script, leading to the first of the distinctions between the refined Hua and the increasingly marginalized Yi. The Han dynasty (221 BCE-206 CE) further contributed to the divide with its creation of a persistent Han cultural identity.
The Han Chinese civilization influenced neighboring states Korea, Japan, Vietnam and Thailand and other Asian countries. Although Han Chinese superiority had only been sporadically reinforced by displays of Chinese military power, the Sinocentric system treated these countries as vassals of the emperor of China, literally "the Son of Heaven" (天子), who was in possession of the Mandate of Heaven (天命), the divine right to rule. Areas outside Sinocentric influence and the divine rule of the Emperor were considered to consist of uncivilized lands inhabited by barbarians.
Throughout history, Chinese frontiers had been periodically attacked by nomadic tribes from the north and west. These people were considered "barbarians" by the Chinese who believed themselves to be more refined and who had begun to build cities and live an urban life based on agriculture. It was in consideration of how best to deal with this threat that the philosopher, Confucius (551 – 479 BCE) was prompted to formulate principles for relationships with the barbarians, briefly recorded in two of his "Analects".
The arrival of European trade and colonialism in the 18th and 19th centuries, exposed Chinese civilization to the developments that had long outstripped China's. As such, the nation was forced to undergo a modification of its traditional views of its relationships with those "barbarians".
