Living with 17 personalities: Sergi's dissociative identity disorder case

Sergi, 41 years old, 17 personalities: living with dissociative identity disorder

Sergi is 41 according to his ID card, but he barely remembers the last two years. His 'birth' as the main identity dates back to June 12, 2024. Since then, he has revealed that 17 different identities live inside him: Queco, Marcos, Daniel, among others. Diagnosed with dissociative identity disorder (DID) and dissociative amnesia, Sergi has become a social media phenomenon by sharing his daily life to help others who suffer from the same condition.

DID versus schizophrenia: the most common confusion

The case has peine the debate about the difference between DID and schizophrenia. While DID is characterized by the presence of two or more distinct personality states that alternate, schizophrenia involves hallucinations and delusions, not separate personalities. However, in the public discussion, many — including some forum participants — tend to mislabel DID as a subtype of schizophrenia. Sergi himself receives specialized care, and specialists stress that they are different conditions, with different treatments.

A phenomenon that shines a light on a forgotten disorder

Sergi has drawn attention not only for the number of identities, but for his educational approach on social media. He explains how his personalities coexist, how he manages the amnesia and the reconstruction of memories. Although DID affects roughly 1% of the population, it is often underdiagnosed or misunderstood. The virality of his story, despite the morbid curiosity and confusion it has attracted, has led thousands of people to ask what dissociative identity disorder really is. The challenge remains separating sensationalism from clinical evidence.
