Recent research has focused on clarifying the neurological basis of symptoms associated with dissociation by studying neurochemical, functional and structural brain abnormalities that can result from childhood trauma. Others in the field have argued that recognizing disorganized attachment (DA) in children can help alert clinicians to the possibility of dissociative disorders. In their 2008 article, Rebecca Seligman and Laurence Kirmayer suggest the existence of evidence of linkages between trauma experienced in childhood and the capacity for dissociation or depersonalisation. They also suggest that individuals who are able to utilise dissociative techniques are able to keep this as an extended strategy to cope with stressful situations.Clinicians and researchers stress the importance of using a developmental model to understand both symptoms and the future course of DDs. In other words, symptoms of dissociation may manifest differently at different stages of child and adolescent development and individuals may be more or less susceptible to developing dissociative symptoms at different ages. Further research into the manifestation of dissociative symptoms and vulnerability throughout development is needed. Related to this developmental approach, more research is required to establish whether a young patients recovery will remain stable over time. Current debates and the DSM-5
A number of controversies surround DD in adults as well as children. First, there is ongoing debate surrounding the etiology of dissociative identity disorder (DID). The crux of this debate is if DID is the result of childhood trauma and disorganized attachment.
Nightmares can also have negative impact on the bed partners life. Content of idiopathic nightmares
Physical aggression is the main theme of nightmares. Other fields, such as interpersonal conflict, failure, helplessness, apprehension, being chased, accidents, evil forces, disasters, insects and environmental abnormalities may also feature in nightmares. Fear is the most frequent emotion associated with nightmares, even if other emotions such as sadness, anger, and confusion can also be present. Criteria
According to the International Classification of Sleep Disorders, the criteria needed to diagnose a nightmare disorder are the following. First, the presence of frequent nightmares that imply danger for the person and impact mood in a negative way is needed. Second, when waking up from nightmares, the person behaves in an alert way. Finally, the disorder has to have a significant impact on the patients personal, social or professional functioning, in areas like mood, sleep, cognition, behaviour, fatigue, family and occupation. Causes
Nightmares can be caused by extreme pressure or irritation if no other mental disorder is discovered. The death of a loved one or a stressful life event can be enough to cause a nightmare but conditions such as post-traumatic stress disorder and other psychiatric disorders have been known to cause nightmares as well. If the individual is on medication, the nightmares may be attributed to some side effects of the drug. Amphetamines, antidepressants, and stimulants like cocaine and caffeine can cause nightmares.
