Top 10 Rarest Mental Illnesses in the World: You will discover a list of some of the most uncommon mental diseases ever documented below. Their symptoms range from having skewed perceptions of the world to complete blindness.
Patients suffering from mental problems often find it difficult to convince others of the seriousness of their conditions because barely one-third of Americans receive appropriate treatment for mental illness.
Having a mental condition that is so extraordinarily unusual makes it even more difficult to detect and, as a result, treat symptoms, which amplifies the difficulty of the situation.
It is my hope that an increased understanding of these conditions would bring some alleviation to those who are affected by them.
Top 10 Rarest Mental Illnesses in the World 2023
1. Body Identity Integrity Disorder
- Symptoms: Intense desire for paralysis or amputation of certain limbs
- Causes: Congenital damage to the parietal lobe
- Number of Cases: Unknown
Body Identity Integrity Disorder (BIID) is an extremely uncommon disorder that has received very little research attention.
Sufferers of BIID express a desire to become paralyzed or to amputate certain limbs because they do not consider those parts of their bodies to be genuine.
Few patients have come out about having BIID since it is considered to be a taboo disease, and many medical experts have failed to recognize it as a valid sickness.
In the past, researchers hypothesized that BIID was caused by a sexual fetish or psychosis; however, recent findings reveal that it is actually an identity disorder.
Damage to the parietal lobe, which is responsible for sensation, perception, and integrating sensory data, was most likely present at birth and is the likely source of the condition.
Have you any idea?
BIID is not mentioned in the International Statistical Classification of Diseases 11 or the Diagnostic and Statistical Manual of Mental Disorders IV due to the fact that so few people have come forward with their experiences.
2. Kluver-Bucy Syndrome
- Symptoms: Several, including inappropriate sexual behaviors, memory loss, and the urge to put various objects in one’s mouth
- Causes: Brain damage
Even though the precise number of people affected by Kluver-Bucy syndrome is unknown, the National Institutes of Health has determined that the condition is an exceptionally rare one.
The condition comprises a multitude of symptoms, some of which are inappropriate sexual behavior, a lack of fear, memory loss, the need to put different objects in one’s mouth, the need to examine everything, visual confusion, and an enormous hunger.
Head trauma, stroke, and herpes simplex encephalitis are the conditions that are responsible for the majority of cases of Kluver-Bucy syndrome.
However, this syndrome can be caused by a very long number of diseases and disorders. Even though there is no known cure for Kluver-Bucy syndrome, there are treatments that have been demonstrated to alleviate its symptoms.
Did you know that humans and rhesus monkeys have been found to have Kluver-Bucy disease? Because specific regions of our brains are more resistant to damage than monkeys are, humans have a significantly lower risk of experiencing the complete spectrum of symptoms than monkeys do.
3. Conversion Disorder
- Symptoms: Any number of neurological difficulties
- Causes: Severe stress
- Number of Cases: 2 to 3 patients per every 100,000 (est. 9,000)
Patients who have conversion disease suffer from neurological symptoms such as blindness and lack of motor function, even though there is no obvious underlying explanation for these symptoms in their physical bodies.
After a period of intense stress, the majority of patients report experiencing symptoms. People who are regularly subjected to sources of stress, such as those with lower socioeconomic situations and officers in the armed forces, are more likely to be affected by post-traumatic stress disorder (PTSD).
Brain imaging studies have demonstrated that people who suffer from conversion disorder have irregular blood flow to various parts of their brains.
The specific source of this condition is not yet established. Symptoms frequently disappear without medical intervention, however, those who experience repeated symptoms have access to treatment options in the field of mental health.
Have you any idea?
Although the symptoms of conversion disorder are not produced by any kind of physical trauma, they are every bit as severe and real as those that are brought on by conventional brain damage.
4. Jerusalem Syndrome
- Symptoms: Anxiety and religious fervor
- Causes: Difficulty coping with reality versus fantasy
- Number of Cases: About 100 people annually
The term “Jerusalem Syndrome” refers to a feeling of being overpowered by the experience of being in Jerusalem. It is likely the outcome of an exaggerated idealization of the location as a sacred land colliding with the fact that it also functions as a conventional city at the same time.
Different degrees of psychosis is caused by the failure of the mind to successfully combine these two concepts and the ensuing disappointment brought on by expectations that are not met.
A compulsive need to recite religious texts, sing holy songs, or deliver sermons are some of the symptoms of religious compulsion.
Other symptoms include anxiousness, a want to view the city alone, a desire to be clean or pure, and a desire to be clean or pure. In general, hospitalization is not necessary for the majority of instances.
Did you know that there is a disorder known as the Paris Syndrome? People suffer from this condition when they visit Paris and find that the city does not live up to their expectations of what it should be like there.
5. Alien Hand Syndrome
- Symptoms: Hand moves autonomously
- Causes: Multiple, all related to brain damage
- Number of Cases: 150, but most likely higher
Because of Alien Hand Syndrome, the affected hand behaves as if it were its own independent entity. The hand maintains the same level of strength as previously and moves in a methodical and organized fashion rather than erratically
. Patients frequently comment that it feels as though someone else is controlling their hands. Alzheimer’s disease, a damaged corpus callosum, and brain lesions are some of the causes that can contribute to this condition, all of which are related to the deterioration of the brain.
Did you know that the “autonomous” hands may conduct routine chores without the owner’s prompting? For example, putting on clothes is one example.
6. Stendhal Syndrome
- Symptoms: Dizziness, heart palpitations, exhaustion, disorientation
- Causes: The art museums in Florence, Italy
- Number of Cases: Unknown, but most likely in the hundreds
The Stendhal Syndrome is an extremely uncommon condition that manifests itself as aggressive and, on occasion, even life-threatening responses to works of art and other culturally significant monuments.
It is something that can only be found in Florence, Italy, which was an essential city in the development of the Renaissance. The earliest case of Stendhal Syndrome ever documented was in the year 1817, and the most recent one was in 2018.
Dizziness, heart palpitations, hallucinations, confusion, and weariness are some of the symptoms that may be experienced.
Psychiatrists believe that the psychological burden of knowing that one stands in a city with an overwhelming history is related to Stendhal Syndrome, despite the fact that there are no causes of Stendhal Syndrome that have been discovered.
When it comes to getting treatment, the physicians advocate getting out of Florence as quickly as you can.
Did you know that people who have suffered in Florence typically worry that the city is full of famous ghosts and death?
7. Cotard’s Syndrome
- Symptoms: Belief that one is dead, nonexistent, or that parts of their body are missing
- Causes: Unknown, but probably brain damage or a history of mental illness
- Number of Cases: 200
When a patient believes that they are dead or that parts of their body are not truly existent, this is a symptom of Cotard’s syndrome, which is also known as the “Walking Corpse” Syndrome.
In the most severe situations, the individual may believe that nothing in the world is real. Having the mistaken belief that one is already deceased might cause a variety of health problems.
Because dead people have no need for food or care, many people with Cotard’s disease choose not to eat or take care of themselves.
In addition to this, they become increasingly antisocial and occasionally hear voices telling them that they are already dead.
People in their middle years who have a history of anxiety, schizophrenia, or substance addiction are most likely to be affected by Cotard’s syndrome.
Have you any idea?
The first person who is known to have suffered from this sickness was a neurologist by the name of Dr. Jules Cotard who lived during the nineteenth century.
8. Gardner Diamond Syndrome
- Symptoms: Spontaneous bruising, swelling, headache, etc
- Causes: Extreme stressors and a history of mental illness
- Number of Cases: 200
Gardner Diamond Syndrome may be a stress reaction, despite the fact that the spontaneous occurrence of bruising is more likely to be interpreted as pointing to a physical than a mental problem.
The body produces chemicals that have a blood-thinning effect when it is under an intense amount of stress.
These chemicals can then cause bruising to occur. In addition to experiencing excruciating bruises, individuals may also experience edema, headaches, and gastrointestinal problems.
The process of diagnosis and therapy typically begins with a psychiatric evaluation, during which the attending physician will ask the patient about the ways in which they have responded to stressful events throughout their lifetime.
Did you know that women under the age of 30 are most likely to be affected by Gardner’s Diamond Syndrome?
9. Alice in Wonderland Syndrome
- Symptoms: Perceiving the world through a distorted lens
- Causes: Brain swelling, Migraine, Creutzfeldt-Jakob Syndrome
- Number of Cases: 180
People who have this illness have a distorted view of the world, similar to how Alice felt after going through the process of growing and shrinking in the children’s books written by Lewis Carroll.
They, along with the things in their environment, have a sense that they are either greater or smaller than they actually are.
In addition to this, they have an erroneous perception of distances and see curves when there should be straight lines.
The Alice in Wonderland Syndrome, also known as AWIS, is typically brought on by brain inflammation in young children.
Migraines are frequently the cause of the syndrome in adults. Around fifty percent of patients are able to make a full recovery with the help of treatment, the specifics of which can change depending on the underlying cause.
However, in severe situations, AWIS can be an indicator of Creutzfeldt-Jakob disease, which is a neurodegenerative condition that ultimately results in death.
Did you know that Creutzfeldt-Jakob disease is a human prion disease? The disease affects one person out of every million.
10. Mietens-Weber Syndrome
- Symptoms: Intellectual disability, small pointed nose, deformed elbows, and opacity in the corneas
- Causes: Genetics
- Number of Cases: 9
The most uncommon form of mental illness on this list is known as Mietens-Weber Syndrome. It is a hereditary illness that can cause mild to moderate mental impairments, as well as dislocated and/or contracted elbows.
Other symptoms may include a shortened or contracted elbow. This far, there have only been nine cases reported.
When four out of six children in a single-family were born with these symptoms, this is when the first known examples of the condition occurred.
The fact that the parents were related is noteworthy; nevertheless, subsequent occurrences have occurred in children whose parents are not related, which rules out incest as the primary cause of the sickness.
Have you any idea?
The first known instances of Mietens-Weber disease were reported in 1966, and the most recent one was documented in 2006.
