Obsessive Compulsive Disorder


It has recently been found that OCD is linked to chromosome 9, in a gene called Protein Tyrosine Phosphokinase (PTPRD). Chromosome 9 has relations to learning and memory in animals, similar to side effects seen in people with OCD.


Symptoms can range from compulsive behavior to social isolation. The most common symptoms are: Compulsive behavior, agitation, compulsive hoarding, hyperactivity, hypervigilance, impulsivity, meaningless repetition of words, social isolation, and ritualistic behavior.

Some of these symptoms can make it very hard to enjoy life to the fullest. Severe OCD cases can result in not even leaving the house due to compulsory tasks.

General Information

It is largely unknown what causes OCD, but it is thought to be genetic or acquired by traumatic experiences, similar to Post Traumatic Stress Disorder (PTSD). OCD causes obsessions in the brain, things such as repeating thoughts, images, or audio in the brain. These obsessions then lead to compulsory habits, taking from a few minutes up to hours on end. Thus is why it is called Obsessive Compulsive Disorder.

Scientists are not exactly sure about how OCD is caused, but due to the relation to chromosome 9, it is thought to be autosomal, but it is unknown on which allele it is carried.


Scientists think that OCD may be caused by lack of serotonin, a neurological "communication device." This is also support that many people with OCD that take serotonin shots have said they feel better and less struck with the obsessions. Other treatments include physical therapy, talk therapy, medication, and sometimes a mix of both.

Research Outlook

Research on OCD is not very high in priority. OCD is not life threatening like other disorders and big research programs are focused on other, more important things. However, there are private scientists researching OCD and are gaining new information each day.

In the US, 1 in 40 adults live with OCD, and 1 in 100 children have OCD.
