Post-traumatic stress disorder,¹ commonly referred to as PTSD, is a psychiatric condition provoked by a traumatic event. Such an event could include war, sexual violence, abuse, torture, or neglect, all of which can be experienced directly or indirectly (i.e., witnessing it happening to someone else or learning that it happened to someone else).
While these traumatic events naturally produce fear and stress, people often recover from these symptoms naturally. However, someone experiencing PTSD continues to experience symptoms after the event, even years into the future.
To be diagnosed with PTSD, an individual must experience the symptoms for at least one month after the traumatic event occurred and experience significant distress or impairment. PTSD can affect anyone, independent of age, ethnicity, or culture.

The symptoms of PTSD can be grouped into four categories:
Intrusion
Avoidance
Negative alterations in cognition and mood
Alterations in arousal and reactivity
Every person with PTSD will present differently, but symptoms typically include:
Flashbacks (dissociative reactions)
Nightmares related to the event
Involuntary and distressing memories of the event
Intense psychological and physiological distress in response to triggers² of the event (e.g., certain smells or noises)
Avoiding triggers that prompt distressing memories or feelings of the event (e.g., external reminders of the trauma)
Avoiding thinking about the event or feelings related to it
Memory loss related to the event
Reduced pleasure in once-enjoyed activities
Increased negative emotional state
Negative beliefs about yourself, other people, and the world in general
Distorted thoughts about situations surrounding the event
Persistent feeling of a low emotional state or constantly in a bad mood
Easily startled
Issues with concentration
Recklessness
Irritability
Sleep disturbance
Hypervigilance
Some symptoms are more obvious than others, but all tend to cause significant problems.
While paranoia is not a symptom of PTSD according to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), it may be exacerbated by other PTSD symptoms.
As mentioned above, hypervigilance is a common symptom of PTSD. Some use the words "paranoia" and "hypervigilance" interchangeably, but they have different definitions.
Hypervigilance³ tends to refer to being very aware of your surroundings, sometimes referred to as “always on guard.” Hypervigilant people are in a constant fight-or-flight state and startle easily.
Paranoia,⁴ however, refers to a mental state in which people are irrationally suspicious of others. They tend to have negative thoughts and delusions about others, as though other people are out to get them.
Another key distinction between the two is that hypervigilant people are often aware of their symptoms but a paranoid person may not be.
While the concepts of hypervigilance and paranoia are different, the two may be related.⁵ The state of constantly being aware of your surroundings can mean that hypervigilant people feel suspicious of those around them. This can prompt paranoia because they’re constantly on the lookout for betrayal.
Other symptoms of PTSD may bring on paranoid symptoms, including sleep disturbance.
One particular study⁶ demonstrated that veterans with PTSD were more likely to struggle with sleep disturbance and paranoid ideation than non-PTSD veterans. Reduced sleep quality has been extensively shown⁷ to promote psychotic-like symptoms, mostly paranoia.
Some researchers have even suggested a new diagnosis⁸ for PTSD that occurs with psychotic symptoms, including paranoia. These people often have far more severe symptoms of PTSD and tend to experience more serious impairments in well-being and overall functioning.
Some studies⁹ suggest that, while paranoia and PTSD are different and distinguishable conditions, they are positively correlated. In other words, they can be predicted by similar factors, which include:
Self-blame
Worry
An altered information-processing style during a traumatic event
Feelings of mental defeat
Studies¹⁰ concerning gang membership also note an increased prevalence of PTSD and paranoia compared to non-gang members.
Additional studies¹¹ have also revealed that negative thoughts about one’s self and others tend to be associated with the relationship between traumatic experiences and paranoia.
Paranoia is a common symptom in other disorders, and paranoid feelings are present in many conditions, including:
Paranoid schizophrenia¹²
Dementia¹³
Psychosis¹⁴
Paranoid personality disorder¹⁵
Paranoid thoughts and symptoms may also be prompted by the use of certain drugs such as cannabis, MDMA, and high doses of methamphetamine.
Both PTSD and paranoia can cause significant harm and various problems in the daily life of the affected person, but many possible treatment options are available. PTSD is often treated using:
Cognitive behavioral therapy
Cognitive processing therapy
Cognitive therapy
Prolonged exposure therapy
Such interventions are strongly recommended by the American Psychiatric Association (APA) for their efficacy. Medications are also helpful and include:
Sertraline
Paroxetine
Venlafaxine
Fluoxetine
These are under conditional recommendation, meaning that they’re prescribed only when necessary. Other non-conventional treatments are also available.
For example, running and other forms of exercise can greatly reduce the symptoms of PTSD when used in combination with talk therapy.
Paranoia treatment¹⁶ may involve talk therapies such as cognitive behavioral therapy and family intervention. When paranoia is in the context of PTSD, treatment of PTSD symptoms may relieve the feelings of paranoia.
Antipsychotics¹⁷ may also be used. Alternative therapies are available as well, including treatments using virtual reality.¹⁸ This targets negative thoughts about oneself and others by using compassionate imagery.
Trauma-focused treatment¹⁹ in PTSD patients with associated psychosis has also demonstrated significant reductions in paranoia without worsening PTSD-related symptoms.
Self-care and coping options are also helpful for paranoia. These include:
Keeping a diary or making notes about your thoughts
Trying to catch paranoid thoughts and challenge them
Looking for support from family or friends
Trying to get enough sleep, eat well, and exercise
While paranoia is not a symptom of PTSD according to the DSM-5, it can occur in people diagnosed with PTSD. These people experience distrust of others and often have difficulty functioning in their daily lives because of their paranoia combined with other PTSD symptoms.
Luckily, a multitude of treatment options is available for PTSD and paranoia.
