Dissociative Identity Disorder (DID) is a severe trauma-related disorder characterised by two or more distinct identity states (or alters), accompanied by significant memory gaps beyond ordinary forgetfulness. Previously called Multiple Personality Disorder, the name was updated in the Diagnostic and Statistical Manual of Mental Disorders to reflect the dissociation of identity that occurs in the condition rather than the literal existence of multiple personalities.
People with DID can develop multiple alters, sometimes numbering into the dozens. ‘Switching’ between alters occurs typically in response to stress, trauma triggers or spontaneously. The frequency of switches also depends from person to person; some individuals rarely switch alters, while others may switch multiple times a day. While alters do not appear simultaneously as separate physical entities, a person may experience internal awareness of them through internal voices or co-consciousness.
Pop fiction often portrays persons with DID as dangerous. In reality, individuals with DID are more likely to harm themselves than others. The risk of self-harm increases with comorbid conditions like depression, PTSD and substance use or poor support. The disorder itself does not inherently make someone violent, rather, it is a response to being a victim of violence.
While data specific to Goa is limited, DID is globally estimated to affect about 1–1.5 per cent of the general population, a prevalence rate similar to schizophrenia. In India, it is frequently underdiagnosed or mislabelled as borderline personality disorder, psychosis, severe depression or even ‘spirit possession’ in certain cultural contexts.
While symptoms often originate in childhood (usually before age nine), a diagnosis is rarely made until adulthood. In children, symptoms may be mistaken for imaginary play or erratic mood shifts. In adults they may manifest as memory gaps (losing time), hearing internal voices, sudden change in voice or body language and childlike behaviour. Because patients may hide symptoms due to shame or fear of stigma, cultural interpretations and media stereotypes, it takes an average of five to twelve years to receive an accurate diagnosis. Diagnosis requires structured clinical interviews, such as the SCID-D, conducted by trained professionals like a psychiatrist or a clinical psychologist specialising in trauma disorders. There are no blood tests or brain scans used in the diagnosis of DID.
People are not born with DID. It develops as a creative coping mechanism in response to chronic, repeated childhood abuse or neglect. When a child lacks a safe attachment figure, dissociation becomes a way to escape an unsupportive reality or a survival strategy, eventually leading to the fragmenting of identity.
DID prevention strategies focus primarily on addressing the root causes of trauma. Preventing childhood trauma, early identification of abuse, providing safe attachment and trauma-informed care are some of the strategies to prevent trauma from escalating and leading to the need to escape the harsh realities. Early trauma therapy may also reduce the severity of DID.
Treatment of DID involves long-term trauma-focused psychotherapy wherein the phases typically include stabilisation and safety, trauma processing and integration or harmonious functioning. While medications do not treat DID directly, they help manage co-morbid symptoms like depression, anxiety and sleep issues. The goal of treatment is to reduce memory gaps, improve emotional regulation and reduce switching. A full ‘fusion’ of identities may happen in some, but many aim for functional multiplicity or stable internal cooperation between the alters.
Individuals with DID can lead stable, productive lives with treatment and support. However, untreated DID may significantly affect daily functioning and relationships. Remember, dissociative identity disorder is not a dramatic movie condition; it is a trauma survival adaptation.
