Obsessive-Compulsive Disorder (OCD), in conjunction with other anxiety disorders, is the sixth largest contributor to non-fatal health loss globally, according to the World Health Organization. More than half a million Australians, or 2% of our population, are living with the disorder.

 

What causes OCD is unknown, but researchers believe that people with OCD have certain areas of their brain that may not respond normally to serotonin, a chemical that some nerve cells use to communicate with each other.

Several studies have shown that lower levels of serotonin can trigger OCD, but there are a number of risk factors that increase a person’s chance of developing this life-altering disorder.

“Although serotonin plays a part in OCD onset, the range of external factors impacting people living with the disorder are varied with some people significantly more likely to develop OCD before adulthood,” The Banyans Health and Wellness Clinical Director Peter Hayton says.

The Spectrum of OCD

Obsessive-Compulsive Disorder (OCD) can also be referred to as Obsessive-Compulsive Spectrum Disorder, as several varying disorders are encompassed in the OCD classification.

The obsessive–compulsive spectrum is a model of medical classification where various psychiatric, neurological and/or medical conditions are described as existing on a spectrum of conditions related to OCD. OCD is usually considered a lifelong disorder and can be mild to moderate, or be so severe and time-consuming that it becomes disabling

Obsessive-Compulsive Spectrum Disorder (OCSD) can include different severities of other disorders, such as Body dysmorphic disorder, Hypochondriasis, Tic disorders, Trichotillomania (hair pulling disorder), Hoarding Disorder, and Excoriation (skin-picking) disorder.

 

Risk factors for OCD

Risk factors for developing Obsessive-Compulsive Disorder (OCD) include:

  • Age and gender;
  • Genetics;
  • Presence of other mental health conditions;
  • Life events;
  • Stress;
  • Pregnancy and postpartum; and
  • Learning.

While the above factors often cannot be controlled, the risk of developing OCD is increased when other manageable risk elements, such as drug and alcohol use, marital status, and unemployment, are considered.

Alcohol and drug consumption increases the risk of developing OCD in people who are predisposed to the disorder.

 

Age and gender

OCD is most commonly triggered in older teens or young adults. Studies indicate that late adolescence is a period of increased vulnerability for the development of OCD. Boys are more likely to experience the onset of OCD prior to puberty and those who have a family member with OCD or Tourette Syndrome are most at risk.

Females are more likely to develop OCD in adolescence and in their 20s.

The disorder affects predominantly female adults, male children, and adolescents.

 

Gender

Gender is a risk factor for developing OCD that varies with age.

Males are at greater risk of developing OCD in childhood, while women have a greater lifetime risk of developing OCD, according to the Journal of Clinical Psychiatry.

Men and women often exhibit different types of OCD. Males are more likely to report obsessions related to sexuality, exactness, and symmetry, while contamination and cleaning obsessions are more likely to be experienced by women.

Genetics

Your genetics are 50% responsible for determining your risk of developing OCD. Having family members with OCD is a high-risk factor, with the likelihood of developing the disorder increasing significantly based on the closeness of that family member. If their OCD began in childhood or as a teenager, the probability rises.

If you, your parent, or a sibling have OCD, there’s a 25% or one in four chance that another immediate family member will also have OCD.

Presence of other mental health conditions

People living with OCD have a higher risk of comorbidity with another mental illness.

“A high percentage of people presenting with OCD also live with depression, anxiety, bipolar disorder, Tourette Syndrome, borderline personality disorder, and schizophrenia,” says Peter.

According to a 2017 study, the most common mental illnesses to exist in conjunction with OCD are major depressive disorder (28.4%), obsessive-compulsive personality disorder (24.5%), generalised anxiety disorder (19.3%), specific phobia (19.2%), and social phobia (18.5%).

Over half (50.5%) of the people with OCD who participated in the study had a co-occurring lifetime diagnosis of major depression.

 

Life events and stress

Traumatic life events, particularly those that occurred in childhood or adolescence, such as sexual and physical assault, death of a parent or loved one, divorce of parents, and witnessing marital violence are major risk factors that can trigger the onset of OCD.

For someone genetically predisposed to OCD, symptoms of the disorder are worsened by stress, but stress alone does not cause OCD.

 

Pregnancy and postpartum

High levels of stress in expectant mothers can impact offspring, increasing the risk of the child developing OCD later in life. For some women, pregnancy and birth itself can trigger OCD.

Extreme stress or OCD in pregnancy can transfer to the unborn child. In some cases, pregnancy and birth can trigger OCD.

 

Learnt behaviours

Obsessive fears and compulsive behaviours can be learned from watching family members or gradually learned over time in home situations. Some people who are predisposed to OCD have learnt unhealthy coping mechanisms during stressful situations by observing parents, siblings, and those living with them.

 

OCD Controllable risk factors

Drug and alcohol use and misuse

People who develop OCD in childhood and the teen years are more likely to engage in drug and alcohol use as a coping mechanism to deal with fear and anxiety. Additionally, drug and alcohol misuse are also linked to the onset of OCD.

“Substance misuse can cause chemical changes in the brain that creates a vulnerability to OCD,” says Peter. “Drug use in conjunction with OCD can create added stress that is triggered by conflict with loved ones, addiction, and difficulty in maintaining employment.”

 

Marital Status

Being married is known to be a buffer against the stresses of everyday life. It is debatable if the distressing nature of OCD is the reason behind a lack of relationship stability, or if being unmarried creates more personal stress and the likelihood of OCD developing is increased.

Marriage can act as a buffer against the stresses of daily life, and OCD is less likely to be overwhelming for married people.

 

Employment status

Being unemployed is a risk factor for OCD, and has wide-ranging effects on both physical and mental wellbeing. Unemployment can be both a cause and a consequence and is like marriage in that respect.
