It has been hypothesized that dissociation may provide a temporarily effective defense mechanism in cases of severe trauma; however, in the long term, dissociation is associated with decreased psychological functioning and adjustment.Other symptoms sometimes found along with dissociation in victims of traumatic abuse (often referred to as "sequelae to abuse") include anxiety, PTSD, low self-esteem, somatization, depression, chronic pain, interpersonal dysfunction, substance abuse, self-harm and suicidal ideation or actions. These symptoms may lead the victim to present the symptoms as the source of the problem.Child abuse, especially chronic abuse starting at early ages, has been related to high levels of dissociative symptoms in a clinical sample, including amnesia for abuse memories. It has also been seen that girls who suffered abuse during their childhood had higher reported dissociation scores than did boys who reported dissociation during their childhood. A non-clinical sample of adult women linked increased levels of dissociation to sexual abuse by a significantly older person prior to age 15, and dissociation has also been correlated with a history of childhood physical and sexual abuse. When sexual abuse is examined, the levels of dissociation were found to increase along with the severity of the abuse.A 2012 review article supports the hypothesis that current or recent trauma may affect an individuals assessment of the more distant past, changing the experience of the past and resulting in dissociative states. Psychoactive substances
Psychoactive drugs can often induce a state of temporary dissociation.
Prevention is the first step in avoiding the development of an arterial insufficiency ulcer. These steps could include annual podiatry check ups that include, "assessment of skin, checking of pedal pulses (assessing for blood flow) and assessing physical sensation". The management of arterial insufficiency ulcers depends on the severity of the underlying arterial insufficiency. The affected region can sometimes be revascularized via vascular bypass or angioplasty. If infection is present, appropriate antibiotics are prescribed. When proper blood flow is established, debridement is performed. If the wound is plantar (on walking surface of foot), patient is advised to give rest to foot to avoid enlargement of the ulcer. Proper glycemic control in diabetics is important. Smoking should be avoided to aid wound healing. Epidemiology
These ulcers are difficult to heal by basic wound care and require advanced therapy, such as hyperbaric oxygen therapy or bioengineered skin substitutes. If not taken care of in time, there are very high chances that these may become infected and eventually may have to be amputated. Individuals with history of previous ulcerations are 36 times more likely to develop another ulcer. See also
