Ten Weirdest Psychological Disorders

Updated on August 6, 2014


They say one out of five Americans suffer from some kind psychological illness, most are common disorders like depression, anxiety, schizophrenia, but what about those who believe that they are a cow or eat inedible items like drywall, or those who believe that a baby doll is their baby? In a world where many shy away from talking about the weird habits that people can develop, there are some really crazy reports of people suffering from the strangest of disorders. Through research, ten psychological disorders stood out the most and here they are.

Number Ten


Erotomania is a strange disorder in which a person believes that somebody is in love with them. This disorder gets stranger as the supposedly 'in love' person turns out to be either a politician or a celebrity, This illness is usually seen with some sort of a psychosis state and is typical with those with schizophrenia and those who suffered from a cerebral aneurysm.

Erotomania patients usually believe that somebody in the media or a politician are sending messages of love through the media to them or by using telepathy to admit their love. The patients then would response by sending letters, videos, and texts to the so-called secret admirer.

Usually this illness is confused with obsessive love although it is different because usually with this illness, the patient can believe multiple people are declaring love to them through the media so they are not signaled on one person.

Since usually this is linked to a psychotic illness, psychotic drugs can decrease or stop this illness.

Number Nine


Life would be so much simpler with this disorder. It is simply the act of believing you are a cow. The patients with this disorder are easy to spot. They usually are on all fours, eat grass, and moos. That's all the information that can be found sadly about this disorder.

I did find a small article that said that the case is an obsessive compulsive disorder that starts with the love of eating greens like salads and then over time that turns into grass and wildflowers,and then eventually going into the cow state. That theory make sense because there is nothing to do with being a cow.

Another theory is that people, definitely those who are very stressed or have trauma, see how simple the lives of cows are and so to escape trauma and stress, the individual starts to act like cows letting them escape from what they are trying to escape from.

Number Eight

Cotard's Syndrome

This is a bizarre disorder in which a person believes that they are dead or that they cannot die and are immortal. Most of the patients have this syndrome triggered when they have a traumatic experience which they believe that they are going to die and so when they wake up in the hospital they will not accept that they are not dead.

There are three stages to this syndrome. The first stage is a state of depression and hopelessness and the hope to die. The second stage is when they supposedly died from a car accident, mugging from wrong, a cold that they believed they got over, just about anything. The third stage is back into depression and delusions.

The patient withdraw from family members. They will withdraw from eating, washing, working, an drinking to the point where if family members do not intervene they will die from dehydration or starvation usually.

They will also start to delusions on the world to the point where it can be confused with Schizophrenia delusions and hallucinogens. There is no cure for this illness and it very rare so they is not that much information on it. Most of what I have found online is individual case studies or experimental cures like using a cold sore medicine and shown to reverse it.

Number Seven

Genital Retraction Syndrome or Koro

Genital Retraction Syndrome is a male psychological illness in which a man believes that his genitalia is shrinking. this would include a obsessive need to measure the length of a male genitalia to ensure that it is not shrinking. The biggest fear is that not only is it shrinking but eventually it would shrink inside of the body which would lead to death.

Although it is more common in males, there has been cases where females would also believe that their nipples and breasts are shrinking and get obsessive just like the males.

Most of the cases in western countries, has to do with the infertility, that they feel so depressed with the lack of being fertile that this illness occurs and usually with therapy and anti-depressive pills this illness will be gone within a couple of weeks.

There is barely any information about the disease itself, just case studies, so it is still quite unknown. Western countries link to infertility cases, and other cultures link this to everything to a flu-like illness to witchcraft.

Number Six

Capgras Delusion

This is an odd illness in which a person believes that a loved one has been replaced by a clone or a look-a-like. Rather the CIA is trying to spy on them, aliens replaced their loved one, or a secret twin switched with her, the sufferer stops trusting the person they perceived to have taken the place of a loved one. This is not like other related diseases where you do not recognize a loved one, instead they will know that the loved one looks and acts and knows all personal secrets but they do not have the feelings they usually have which is why they believe they are impostors. It is basically like a stranger replaced a family member to the patient. They do not have any emotional attachment.

There is no real known cause however it is suspected that usually a head injury is involved. Lesions or damage to the brain can cause a lot of issues. Most patients show psychotic episodes as well as other organic causes which makes it had to pinpoint. Most researchers now believe that it is a mix of organic and psychotic causes.


Number Five

Paris Syndrome

Ever been on vacation and been really disappointed? Well Paris Syndrome is exactly that. Usually only seen in Japanese who travel to Paris, it is sad that they are so disappointed in Paris that they have a major breakdown.

Anybody who have been to Paris probably will agree, the hype of a romantic city full of beauty love is not really reality. Most people actually who have traveled to Paris have come back with the same response which is that it was a let down.

While, Paris is such a huge ideal place in Japan that when they get there everything they believed to be is different from what they imagined. This leads to a panic attack due to culture shock. In the media, Paris is this beautiful open city that is friendly and quiet and in reality it is like every city, there is parts that are loud, and people who are friendly, and overcrowded transportation which is not what is expected. So Japanese people feel like the city they want to visit is gone.

Some of the signs include acute delusions, dizziness, sweating, hallucinations, depression and feelings of persecution. French are a lot more open in terms of talking than the Japanese who are raised to be quiet and humble in public so that can be one of the reasons they have such a hard time. Luckily this is short lived although it does make some not want to travel again for a while.

Number Four

Stockholm Syndrome

Stockholm Syndrome is a strange disorder in which a kidnapped victim emotionally bonds with their kidnapper. This is done in stages. The first stage is learning to stop grieving for their situation and instead focus on the kidnapper's perspective for the kidnapping and the rapes and disciplines that the kidnapper does.

From that stage comes the next where the victim will start to try to please the kidnapper in order to keep themselves alive. If the kidnapper wants him or her to cook dinner they will do that, if they want to do anything sexual, the victim would do that.

Then comes the stage where the victim starts to understand that the kidnapper is just as human as everybody else. This in returns lowers the threat level of the kidnapper to the victim. This in return will make the kidnapper lower his or her guard and even share personal information with the victim. This turns into conflicting emotions of anger, pity, and even some confusion in terms of love for the victim which is dangerous because they can stop seeing it as a kidnapping

After this point, the victim will start hating her or his family members, friends, and relatives, and instead start to love the kidnapper and want to protect him or her from getting arrested.It is hard for the victim to separate their feelings after the kidnapping ends leading to problems with reporting them and years of therapy to get over it.

Number Three

Lima Syndrome

Linked to Stockholm Syndrome, Lima Syndrome is the development for sympathy for victims by abductors. Although there is barely any information about this disorder, there has been many cases of it including an 1996 hostage situation in Peru when within hours, the abductors let all of the victims go without demanding any money or anything. They felt so much sympathy that they could not continue with the hostage situation.There has also been reports of kidnappers letting their victims go and even drive them back to their homes due to feeling attached to the victims.


Number Two


Bibliomania is a wonderful strange and rare disorder in which a person gets so obsessed with books that they overcome their lives. It's a form of hoarding. The patients would spend all of their paychecks on buying books, they can buy the same book countless of times, definitely in different editions and copies and translations.They will also hoard books that have little value but because it's a book they will buy.

Just like any other obsessive traits, the cure is by cognitive behavioral therapy. The only symptoms involved seems to hoarding a lot of books and the finical and social damage that it does.

Number One


The last one is a very interesting psychological disorder in which a person decides that they taste better than anything else. In other words they start to eat themselves. Although also used to describe the process of a person's body eating itself, usually the tissues and then the organs.

Although most people have a mild form of this by biting nails or biting lips, only a few go onto actually trying to eat their own flesh and is usually just tear into the dead skin around the fingernails or lips making a lot of damage and can even cause bacterial infections or gnaw off fingers.

This does not include instances where self mutation is used to cut off limbs and then eat, that is another form of a eating disorder which is related to a different variety of self-cannibalism. Autophagia is usually just focused on the skin around cuts or died skin around fingernails and lips.

The causes are unknown but the best one they have is a stress related OCD episode, where they just tear and tear with teeth over skin. It could also be a form of self-injury, or a sign of malnutrition,

This is the only one which is common in its mild form but in itrs severe form is very uncommon. Also I believe its more uncommon because most people involve from just biting the skin around nails and sucking blood that causes injury to actually cutting and doing another disorder of the self-cannibalism slide.

In Conclusion

What makes people so interesting is how different everybody is and how odd a chemical switch, a misplaced axon in the brain, genetics, or even depression/anxiety can produce such strange disorders. Some disorders I did not include are just as interesting and will be added in upcoming hubpage post of mine including the weirdest phobias that I will post on Friday. I hope somebody learned something new from this post and you got some information on some of the more misrepresented disorders like Autophagia which many believe they full on cannibalize themselves or Riley-Day Syndrome who many believe is just the inability to feel pain even through there is a lot more to the disorder than what most people describe on posts like this.
