Paranoia: the causes

Paranoia is a relatively rare psychiatric disorder, affecting about 0.03% of the general population. Paranoid personality disorders are more common, with 0.4 to 4.4% of the population affected.

The causes of paranoia are multifactorial. Family first. The existence of a family history of schizophrenia is indeed associated with a greater risk of developing a paranoid personality or paranoia. Without the link between schizophrenia and paranoia being well understood.

In the same way, it is more common to suffer from a paranoid personality when a primary parent has suffered from paranoia. These family aggregations have been corroborated by genetic studies. It is known, however, that genetic influence exists as well as environmental factors.

In the nineteenth century, Sigmund Freud described paranoia as a neurosis designed to combat unconscious homosexual tendencies. But fortunately, nowadays, this understanding has evolved. Today, psychoanalysts believe that early developmental suffering (emotional deprivation, humiliation, maltreatment) could be involved in the appearance of paranoia or paranoid personality. Self-representation as someone great would hide a deep sense of inferiority.

Certain psychiatric pathologies are likely to provoke a paranoid delusion, especially in the moments of anxious or delusional decompensation: bipolar disorder, dementia and schizophrenia.

Finally, the causes of a paranoid delirium can be toxic, without it being possible to speak properly of paranoia. In particular, alcohol, cannabis and cocaine may cause temporary paranoid delusions.
