Denial and minimizing is often seen in genuine PTSD and, hence, should be a target of detection and measurement.

Do You Have DID?Determining if you have DID isn’t as easy as it sounds. In fact, many clinicians and psychotherapists have such difficulty figuring out whether or not people have DID that it typically takes them several years to provide an accurate diagnosis. Because many of the symptoms of DID overlap with other psychological diagnoses, as well as normal occurrences such as forgetfulness or talking to yourself, there is a great deal of confusion in making the diagnosis of DID. Although this section will provide you with information which may help you determine if you have DID, it is a good idea to consult with a professional in the mental health field so that you can have further confirmation of your findings.

My own studies on the natural history of DID indicate only 20% of DID patients have an overt DID adaption on a chronic basis, and 14% of them deliberately disguise their manifestations of DID. Only 6% make their DID obvious on an ongoing basis. Eighty percent have windows of diagnosability when stressed or triggered by some significant event, interaction, situation or date. Therefore, 94% of DID patients show only mild or suggestive evidence of their conditions most of the time. Yet DID patients often will acknowledge that their personality systems are actively switching and/or far more active than it would appear on the surface (Loewenstein et al., 1987).R.P.

In general, fatigue is not as severe in depression as in ME/CFS. Joint and muscle pains, recurrent sore throats, tender lymph nodes, various cardiopulmonary symptoms (55), pressure headaches, prolonged post-exertional fatigue, chronic orthostatic intolerance, tachycardia, irritable bowel syndrome, bladder dysfunction, sinus and upper respiratory infections, new sensitivities to food, medications and chemicals, and atopy, new premenstrual syndrome, and sudden onset are commonly seen in ME/CFS, but not in depression. ME/CFS patients have a different immunological profile (56), and are more likely to have a down- regulation of the pituitary/adrenal axis (57). Anhedonia and self- reproach symptoms are not commonly seen in ME/CFS unless a concomitant depression is also present (58). The poor concentra- tion found in depression is not associated with a cluster of other cognitive impairments, as is common in ME/CFS. EEG brain mapping (59,60) and levels of low molecular weight RNase L (21,26) clearly distinguish ME/CFS from depression.

The SCID-D may be used to assess the nature and severity of dissociative symptoms in a variety of Axis I and II psychiatric disorders, including the Anxiety Disorders (such as Posttraumatic Stress Disorder [PTSD] and Acute Stress Disorder), Affective Disorders, Psychotic Disorders, Eating Disorders, and Personality Disorders.The SCID-D was developed to reduce variability in clinical diagnostic procedures and was designed for use with psychiatric patients as well as with nonpatients (community subjects or research subjects in primary care).

Depression, somehow, is much more in line with society's notions of what women are all about: passive, sensitive, hopeless, helpless, stricken, dependent, confused, rather tiresome, and with limited aspirations. Manic states, on the other hand, seem to be more the provenance of men: restless, fiery, aggressive, volatile, energetic, risk taking, grandiose and visionary, and impatient with the status quo. Anger or irritability in men, under such circumstances, is more tolerated and understandable; leaders or takers of voyages are permitted a wider latitude for being temperamental. Journalists and other writers, quite understandably, have tended to focus on women and depression, rather than women and mania. This is not surprising: depression is twice as common in women as men. But manic-depressive illness occurs equally often in women and men, and, being a relatively common condition, mania ends up affecting a large number of women. They, in turn, often are misdiagnosed, receive poor, if any, psychiatric treatment, and are at high risk for suicide, alcoholism, drug abuse, and violence. But they, like men who have manic-depressive illness, also often contribute a great deal of energy, fire, enthusiasm, and imagination to the people and world around them.

...The vast majority of these [dissociative identity disorder] patients have subtle presentations characterized by a mixture of dissociative and PTSD symptoms embedded with other symptoms, such as posttraumatic depression, substance abuse, somatoform symptoms, eating disorders, and self-destructive and impulsive behaviors.2,10A history of multiple treatment providers, hospitalizations, and good medication trials, many of which result in only partial or no benefit, is often an indicator of dissociative identity disorder or another form of complex PTSD.

In this chapter I restrict myself to exploring the nature of the amnesia which is reported between personality states in most people who are diagnosed with DID. Note that this is not an explicit diagnostic criterion, although such amnesia features strongly in the public view of DID, particularly in the form of the fugue-like conditions depicted in films of the condition, such as The Three Faces of Eve (1957). Typically, when one personality state, or ‘alter’, takes over from another, they have no idea what happened just before. They report having lost time, and often will have no idea where they are or how they got there. However, this is not a universal feature of DID. It happens that with certain individuals with DID, one personality state can retrieve what happened when another was in control. In other cases we have what is described as ‘co-consciousness’ where one personality state can apparently monitor what is happening when another personality state is in control and, in certain circumstances, can take over the conversation.

...When different identity states convey contradictory information and then have amnesia for what the other identity states said, the patient may be thought to be lying. This can appear to be characterological mendacity when it is not.

Interestingly, the patients who presented to me self-diagnosed [with Dissociative Identity Disorder had tried to tell previous therapists of their plight, but had been disbelieved. These therapists had used fallacious 'capricious criteria' (KIuft, 1988) to discredit the diagnosis; e.G., that the patient could not possibly have MPD because she was aware of the other alters [sic!].
