The Multiscale Dissociation Inventory (MDI) is a comprehensive, self-administered, multiscale instrument developed by Paul F. Dell. [1] It is designed to assess the domain of dissociative phenomena. [2] The MDI measures 14 major facets of pathological dissociation and uses 23 scales to diagnose dissociative disorders. [1] [3]
DES is intended to be a screening test, since only 17% of patients with scores over 30 will be diagnosed with having dissociative identity disorder. [2] Patients with lower scores above normal may have other post-traumatic conditions. The DES-II contains the same questions but with a different response scale. [3]
Dissociation is commonly displayed on a continuum. [18] In mild cases, dissociation can be regarded as a coping mechanism or defense mechanism in seeking to master, minimize or tolerate stress – including boredom or conflict. [19] [20] [21] At the non-pathological end of the continuum, dissociation describes common events such as daydreaming.
There are ranges of dissociation and its related symptoms. “Daydreaming can be a very light dissociative state,” says Dr. Clouden. “Your body is physically there, but your mind is off ...
Dissociative identity disorder is a rare condition where a person's mind is divided into various self-states. It looks different in child and adults.
Derealization is a subjective experience pertaining to a person's perception of the outside world, while depersonalization is a related symptom characterized by dissociation towards one's own body and mental processes. The two are commonly experienced in conjunction with one another, but are also known to occur independently.
No laboratory test for depersonalization-derealization disorder currently exists. [11] As patients with dissociative disorders likely experienced intense trauma in the past, concomitant dissociative disorders should be considered in patients diagnosed with a stress disorder (i.e. PTSD or acute stress disorder). [50]
Dissociative disorders are characterized by distinct brain differences in the activation of various brain regions including the inferior parietal lobe, prefrontal cortex, and limbic system. [16] Those with dissociative disorders have higher activity levels in the prefrontal lobe and a more inhibited limbic system on average than healthy ...
