Reduplicative paramnesia
The patient believes that he has already been there, when he firmly believes in what he sees or perceives in spite of the existence of facts that contrast it. A subset of the delusional misidentification syndromes (DMS) is characterized by the subjective conviction of an individual, that a place, person or event is duplicated and as such, these are described as reduplicative misidentification syndromes (RMS). The subjective belief that a place has been duplicated, existing in at least two locations simultaneously, is termed reduplicative paramnesia (RP) and unlike other duplicative syndromes, is thought to be mainly due to a neurological cause. As such, RP will be the main focus of this review. In general terms, we can mention that reduplicative paramnesia has its origin mainly in neurological damages that affect different areas of the brain in charge of the way of processing the information of the world. This means that if we have a lesion in a certain sector of the brain, this will have as a consequence some alterations in our daily activities.



                                                Capgras syndrome


Capgras syndrome is a rare condition in which someone believes that their loved ones or others they know have been replaced with doubles or imposters. The belief is so real that nothing can correct this illusion. You may also hear it called imposter syndrome. But this condition is different from the more common “imposter syndrome” that you may have heard about. If people have other brain conditions they are also more likely to have Capgras syndromes, such as Parkinson's or epilepsy, in people who've had a stroke or a traumatic brain injury, or those with schizophrenia or bipolar disorder.

There are two systems at work in your brain when you see a familiar face. The central nervous system scans the features of the face. The extended nervous system relays emotional information related to that face. Doctors still don't know exactly how Capgras syndrome develops, but think a broken connection between those two systems prevents normal face recognition.

  Hallucinogen Persistent Perceptual Disorder Hallucinogen Persistent Perceptual Disorder is a disorder characterized by a continuous presence of visual disturbances reminiscent of those generated by the ingestion of hallucinogenic substances, if you have HPPD you will suffer from hallucinations. Prior use of hallucinogens by the person is necessary, though not sufficient, to diagnose someone with the disorder. For an individual diagnosed with HPPD, the symptoms cannot be due to another medical condition, in fact HPPD is distinct from psychological flashbacks for reasons of its relative permanence; while flashbacks are transient, HPPD is persistent. As of today, there is still no cure available for HPPD. The main treatments attempt to reduce symptoms and distress without treating underlying causes, if you have HPPD you should seek professional treatment.

  Stockholm Syndrome It is a temporary psychological disorder that, for example if the abducted person finds something good in the abductor's actions, he or she will fall in love with him or her. In these cases, the person wouldn't know whether what is happening at that moment is good or bad. Many psychologists and medical professionals consider Stockholm syndrome to be a coping mechanism, or a way that helps victims deal with the trauma of a frightening situation. In fact, the history of the syndrome may help explain what it is. It was not until 1973 that this response to captivity or abuse was given a name. On this date two men held four people hostage for six days after a bank robbery in Stockholm, Sweden. After the hostages were released, they refused to testify against their captors and even began raising money for their defense. HIGH PROFILE CASE: Patty Hearst. Perhaps most famously, the granddaughter of businessman and newspaper publisher William Randolph Hearst was kid

  Schizotypal disorder They are considered strange people, when they behave differently and usually have few or no close relationships. They do not understand very well the relationships with one, two or a group of people. For this reason, unfortunately, these individuals if present symptoms or characteristics of social or interpersonal deficits. This is due to the fact that they do not pay due attention to it and that makes it become a much more serious problem, due to their behavior and poor management of their emotions.    This is most often observed in the stages of adolescence and childhood. When they have difficulty communicating properly, this becomes a great source of ridicule towards these individuals.
