People strive to understand each other. Yet, there are some things and attitudes of others that are beyond our understanding. Thankfully, there are certain individuals whose endeavour is to study the traits of other people. We have heard a lot about some famous psychological disorders such as schizophrenia, obsessive-compulsive disorder and so on. However, there are disorders that most people have not heard of - since, there are also rare cases involving these bizarre mental disorders. As to help us understand, here are the five weird psychological disorders ever noted. Alien Hand Syndrome Having heard of alien may sound cool. However, alien hand syndrome can be hard to imagine especially for the person who suffers from it. This disorder refers to a person whose arms seem to have a mind of its own. It moves around and grabs anything. But, it does it without the control of the person to whom it belongs. Expectedly, this syndrome brings nightmare to the sufferer. Thus, it may lead to distress, who to the part of the sufferer, refer to a rogue arm as though it was another entity. Autophagia Autophagia is serious condition of eating yourself, or parts of your body - often by simply biting and chewing impulsively. This type of disorder can range from very mild to life-threatening. A person with autophagia apparently begins by merely biting his own nails - but may end up mutilating himself/herself. Psychological or mind therapy like Hypnotherapy SA is beneficial to this condition. Still, this is a serious matter that highly needs the intervention of specialists. Taijin Kyofusho This is a weird psychological disorder common in Japan, or at least to those people who were raised according to the customs and social expectations of Japanese culture. This phenomenon is not surprising in Japan, since their culture is known for placing great value in appearances and social etiquette. Taijan Kyofusho is described as having extreme fear of social interactions. The sufferer has great anxiety that things could go wrong like having offensive body odour or offending someone as they interact. Thus, this may result to being aloof. Talking to a counsellor or a therapist will greatly help to develop optimistic views. Erotomania This disorder is characterised by having a delusion that someone is madly in love with him. What makes this more bizarre is that the person who is supposedly in love is someone of higher status - commonly a celebrity. The delusion of the person having erotomania is hard to break even if the person who is supposedly in love with them strongly denies it. It is hard to convince the deluded individual having a thought that the supposed lover is taking advantage of him/her. Unfortunately, there is no special treatment to this case. But undergoing hypnotherapy Adelaide sessions are said to help restructure the delusion. Riley-Day Syndrome It is also known as Familial Dysautonomia. Riley-Day Syndrome is genetically inhabited but it can only be passed on by both parents. This disorder affects the development of the autonomous nervous system. Thus, the highlight of this disorder is the inability to produce tears and feel pain. That may sound pretty cool. Yet, the sensation of pain will help us acknowledge when something needs fixing. Thus, without pain we may not understand what our body is up to. These fascinating mental disorders truly exist. The point of discussing this is to bring enlightenment to recognise these people suffering from psychological disorders. They are not meant to be despised nor feared, rather to be understood.
