Have you ever felt like someone is watching you? Or maybe you were convinced your coworker was trying to take your job. In these cases, you might be feeling paranoid. Paranoia is the feeling of being threatened or persecuted without any proof of that being the case. Paranoia persists even as evidence stacks up against it. Although it is not a diagnosable mental health condition, it is a common symptom of many mental illnesses. This article will cover the signs, causes, and treatment for paranoia.

What Is Paranoia?

Paranoia is a feeling. It can come in many shapes and sizes, but the basic thought behind it is that someone is out to get you. The harm you fear could be physical, financial, relational, or emotional. 

For example, people with paranoia might be convinced someone is following them, stealing from them, lying to them, or cheating on them. This belief will persist despite proof of the contrary. 

Symptoms of Paranoia

Symptoms of Paranoia will depend on the exact type of paranoia, but general symptoms will include:

  • Constant suspicion or mistrust of others
  • Belief that people are lying, deceiving, or plotting harm
  • Feeling targeted, watched, or followed
  • Interpreting harmless remarks or events as personal threats
  • Difficulty confiding in or trusting even close friends or family
  • Defensive or hostile reactions to perceived criticism
  • Extreme sensitivity to rejection or slights
  • Holding strong, unfounded beliefs despite evidence to the contrary
  • Anxiety, agitation, or restlessness
  • Social withdrawal or isolation to avoid perceived threats
  • Difficulty relaxing or feeling safe

A paranoid person will get defensive when they are challenged and may even turn on the person helping them, claiming that they’re out to get them as well.

What Are the Four Types of Paranoia?

4 types of paranoia

Symptoms of paranoia will depend on the underlying belief. For example, someone who is paranoid that their partner is cheating on them will have a different belief system and behaviors than someone who is paranoid that they are being stalked. 

There are many different ways to define paranoia and the many subtypes it can present. One way is to group it by its underlying belief. In this way, there are four types of paranoia:

Here are brief definitions of those types of paranoia:

  • Persecutory paranoia: The belief that others are out to harm, spy on, harass, or conspire against you. Example: Checking your car, clothes, and house every night for recording equipment because you believe someone is stalking you. 
  • Grandiose paranoia: The belief that you have special powers, importance, or status, often combined with suspicion that others envy or oppose you. Example: Believing a coworker is trying to undermine and sabotage you so they can take your job. 
  • Jealous paranoia: The irrational belief that a partner is unfaithful, despite little or no evidence. Example: Going through your partner’s phone because they “sounded a little off” that morning. 
  • Somatic paranoia: The belief that your body is diseased, infested, or abnormal in some way, even when medical evidence shows otherwise. Example: Going to the doctor when you have a minor headache because you’re convinced it’s a tumor.

These are far from the only ways paranoia can show up. In paranoid disorders, which we talk about below, it can show up differently. 

What Causes Paranoia

Paranoia is a common symptom in many mental health disorders, although these disorders are not the only cause of paranoia. Trauma, substance abuse, insomnia, anxiety, and medical changes can also cause paranoia.

Paranoia disorders can include:

  1. OCD ParanoiaObsessive-Compulsive Disorder (OCD) involves unwanted, intrusive thoughts (obsessions) and repetitive behaviors or mental rituals (compulsions) that try to reduce anxiety. Some people with OCD may feel paranoid about contamination, safety, or harm. For example, they might think they will get sick from touching objects or worry that others will be hurt if they don’t perform certain rituals.

  1. Bipolar ParanoiaBipolar disorder causes extreme mood changes between manic highs and depressive lows. During these episodes, some individuals may experience paranoid thoughts. They might feel that others are out to get them, that there is a plot against them, or that people are judging their actions. Paranoia is not present in everyone who has Bipolar Disorder.

  1. SchizophreniaSchizophrenia is a serious mental health disorder that features distorted thinking, hallucinations, delusions, and difficulty distinguishing reality from imagination. Paranoia is a key symptom, often appearing as persecutory delusions. This means the person believes others are spying on them, trying to control them, or wanting to harm them. It can also show up as grandiose delusions, where individuals think they are sent by a higher power or have special abilities.
  2. Paranoid Personality Disorder (PPD): PPD is a personality disorder defined by a long-term pattern of distrust and suspicion of others without good reason. Paranoia is the primary trait—people with PPD often misinterpret others’ actions as hostile or deceptive, even when there is no evidence to support such views.
  3. Delusional Disorder: Delusional disorder includes strong, persistent false beliefs (delusions) that are not based in reality. Paranoia appears as persecutory or jealous delusions. For example, an individual may believe that someone is plotting against them or that their partner is unfaithful.

If you believe you have a paranoid disorder or are experiencing large amounts of paranoia, reach out to a mental health professional. Psychiatrists and licensed therapists can diagnose and treat paranoid disorders. 

How to Treat Paranoia

Treatment of paranoia will depend on the underlying cause. For psychiatric conditions like the ones listed above, treatment usually involves a combination of medication and therapy. In both cases, a primary goal will be building trust with your therapist and psychiatrist. 

Paranoia, like most mental health symptoms and conditions, exists on a spectrum. On the high end of the spectrum are disorders like Schizophrenia or Paranoid Personality Disorder. On the lower end of the spectrum can exist people who don’t have a diagnosis and aren’t fully impaired by their paranoia, but who still struggle with it.

For example, someone may have trouble keeping long-term relationships because they always end up paranoid that their partner is cheating. Or someone with acute anxiety is paranoid that something bad will happen to them whenever they leave the house.

Therapy is still recommended in these cases, as the paranoia may be a symptom of a deeper anxiety disorder. However, it is also possible to treat this level of paranoia through coping mechanisms and a strong support system. Here are some tips:

  1. Identify your triggers: What causes your paranoia? What happens directly before a spike of paranoia?
  2. Communicate your triggers to your loved ones: A strong support system is crucial. Even if it’s difficult, try talking to someone you trust about your paranoia and triggers. They can help you get through difficult times. 
  3. Challenge the thoughts: Try replacing paranoid thoughts with positive (or neutral) thoughts. For example, whenever you think, “My neighbor is spying on me.” Try to rebuke that thought with “I know my neighbor, and it’s unlikely they are spying on me.” Even if you don’t fully believe this new thought, it’s good practice. 
  4. Self-regulate and ground through mindfulness exercises: When you’re feeling paranoid, don’t act on that feeling. Instead, take a breath and engage in a coping mechanism. It could be going for a walk, baking bread, taking a cold shower, listening to music, calling a friend, or anything else that regulates your nervous system and reminds you that you are safe. 

Finally, it’s a good idea to talk to a therapist, especially if the paranoia persists. 

Treating paranoia can take time because of the fear and mistrust that surround the emotion. Remember that it is possible with patience and the right therapist.

For example, someone might think they are being followed, believe they have special abilities, or feel that others are plotting against them.
