OCD Obsessive Compulsive Disorder Explained: Causes, Symptoms & Treatments

What is OCD Obsessive Compulsive Disorder?

OCD, short for Obsessive Compulsive Disorder, is a mental health condition that affects millions of people worldwide. It’s characterized by unwanted thoughts (obsessions) and repetitive behaviors (compulsions) that individuals feel driven to perform. OCD is characterized by obsessional thinking, compulsive behaviour, and varying degrees of anxiety,depression, and depersonalization. The outstanding symptom is a feeling of subjectivecompulsion— which must be resisted to carry out some action, to dwell on an idea, to recall an experience, or ruminate on an abstract topic.

Unlike common habits such as double-checking the door lock, OCD behaviors can be time-consuming, distressing, and disruptive to everyday life. People with OCD often recognize their thoughts and behaviors as irrational, yet feel powerless to stop them.

Key Characteristics of OCD

• Persistent, intrusive thoughts that trigger anxiety.
• Repetitive actions or rituals meant to reduce anxiety.
• An ongoing cycle of obsessions and compulsions.

Difference Between OCD and Normal Habits

Many people like order, cleanliness, or double-checking things, but OCD goes far beyond that. A person with OCD might wash their hands 50 times a day or spend hours rearranging items until they feel “just right.” The difference lies in the level of distress and interference in daily life.

Causes of OCD: Why Does It Happen?

OCD doesn’t have a single cause but develops from a mix of biological, genetic, and environmental factors.

Genetic and Biological Factors

• Research shows that OCD tends to run in families.
• Imbalances in serotonin, a brain chemical, may contribute to symptoms.

Environmental Triggers

• Trauma, stress, or major life changes can trigger OCD.
• Childhood infections like strep throat may increase risk in rare cases.

Brain Chemistry and OCD

Brain scans reveal differences in the frontal cortex and subcortical structures of individuals with OCD, highlighting its neurological roots.

Symptoms of OCD Obsessive Compulsive Disorder

OCD symptoms fall into two main categories: obsessions and compulsions.

Obsessions: Unwanted Thoughts and Images

Obsessions are recurrent persistent thoughts, impulses,
or images that enter the mind despite efforts to exclude
them. One characteristic feature is the subjective sense
of a struggle— the patient resists the obsession, which
nevertheless intrudes into awareness. Another charac-
teristic feature is the conviction that to think something
is to make it more likely to happen. Obsessions are rec-
ognized by the person as his own and not implanted
from elsewhere (in contrast to delusions of thought
insertion). Another important distinction from delu-
sions is that obsessions are regarded as untrue or sense-
less. They are generally about matters that the patient
finds distressing or otherwise unpleasant. They are
often, but not always, accompanied by compulsions.   

Although the content (or themes) of obsessions are
various, most of them can be grouped into one or other
of six categories:

● dirt and contamination
● aggression
● orderliness
● illness
● sex
● religion.

Thoughts about dirt and contamination are usually
associated with the idea of harm to others or self through
the spread of disease. Aggressive thoughts may be about
striking another person or shouting angry or obscene
remarks in public. Thoughts about orderliness may be
about the way objects are to be arranged or work is to be
organized. Thoughts about illness are usually of a fearful
kind— for example, a dread of cancer. Obsessional ideas
about sex usually concern practices that the individual
would find shameful. Obsessions about religion often
take the form of doubts about the fundamentals of belief
(e.g. ‘does God exist?’) or repeated doubts about whether
sins have been adequately confessed (‘scruples’).

Compulsions: Repeated Actions and Rituals

Compulsions are repetitive and seemingly purposeful
behaviours that are performed in a stereotyped way
(hence the alternative name, ‘compulsive rituals’) in
response to an obsession. They are accompanied by a
subjective sense that the behaviour must be carried
out and by an urge to resist it. The compulsion usually
makes sense given the content of the obsession. For
example, a compulsion to wash the hands repeatedly is
usually driven by obsessional thoughts that the hands
are contaminated. Sometimes obsessional ideas concern
the consequences of failing to carry out the compulsion
in the ‘correct’ way— for example, that another person
will suffer an accident. Compulsions may cause prob-
lems for several reasons.

● They may cause direct harm (e.g. dermatitis from
excessive washing).

● They may interfere with normal life because of the
time they require.

● Although the compulsive act transiently reduces the
anxiety associated with the obsession, in fact the com-
pulsions help to maintain the condition. Strategies to
reduce them are central to behavioural treatments of
obsessive– compulsive disorder.
There are many kinds of compulsive acts, but four
types are particularly common.

● Checking rituals are often concerned with safety— for
example, checking over and over again that the fire has
been turned off, or that the doors have been locked.

● Cleaning rituals often take the form of repeated hand
washing, but may involve household cleaning.

● Counting rituals usually involve counting in some spe-
cial way— for example, in threes— and are frequently
associated with doubting thoughts such that the count
must be repeated to make sure that it was carried out
adequately in the first place. The counting is often
silent, so an onlooker may be unaware of the ritual.

● In dressing rituals the person lays out clothes, or puts
them on, in a particular way or order. The ritual is
often accompanied by doubting thoughts that lead to
seemingly endless repetition.

How OCD Affects Daily Life

OCD can consume several hours a day, making work, school, and relationships difficult. Many sufferers feel embarrassed or ashamed, leading to isolation.

Types of OCD

1. Contamination and Cleaning OCD – Fear of germs, leading to excessive cleaning.
2. Checking and Safety OCD – Constant checking of doors, stoves, and safety hazards.
3. Symmetry and Order OCD – Need for things to look perfect or symmetrical.
4. Intrusive Thoughts OCD – Disturbing mental images or fears without visible rituals.

Diagnosis and Misconceptions

How OCD is Diagnosed by Professionals

• Conducted by psychiatrists using structured interviews.
• Often involves standardized tools like the Yale-Brown Obsessive Compulsive Scale (Y-BOCS).

Myths and Misunderstandings about OCD

• Myth: OCD is just about being neat.
• Truth: OCD is a serious mental illness with many subtypes beyond cleanliness.

Effective Treatment Options for OCD

What patients need to know :

Treatment should begin with an explanation of the
symptoms, and, if necessary, with reassurance that these
symptoms are not an early sign of insanity (a common
concern of obsessional patients). If the patient agrees,
their partner or another close relative can be involved
in educational sessions about the nature and treatment
of the disorder. Patients and family members are often
helped by reading a book on OCD.
Obsessional patients may attempt to involve other
family members in their rituals. If this happens, the
relatives should be helped to find ways of resisting such
requests in a way that is firm and appropriately sym-
pathetic. In particular, they need to understand that
repeated reassurances about obsessional ruminations do
not help.

Cognitive Behavioral Therapy (CBT) and ERP

Exposure and Response Prevention (ERP), a type of CBT, is considered the gold standard treatment. Patients face their fears gradually without performing compulsions.

Medication and Brain Chemistry Balance

Selective Serotonin Reuptake Inhibitors (SSRIs) help balance brain chemicals and reduce OCD symptoms.

Lifestyle and Self-Help Strategies

• Regular exercise to reduce stress.
• Healthy sleep patterns.
• Limiting caffeine and alcohol intake.

Living with OCD: Coping Strategies

Building a Support System

Joining OCD support groups or talking with loved ones reduces feelings of isolation.

Stress Management and Relaxation Techniques

Breathing exercises, yoga, and progressive muscle relaxation ease anxiety.

Mindfulness and Meditation Practices

Mindfulness helps sufferers detach from intrusive thoughts without judgment.
