Psychosis

Psychosis is a mental health condition characterized by a disruption in an individual’s perception of reality. This disturbance may manifest in various forms, including delusions (firmly held false beliefs), hallucinations (perceiving sights, sounds, or sensations that are not present), disorganized speech, and impaired insight or judgment. These experiences can significantly impact the person’s daily life, relationships, and sense of identity.

While psychosis is a hallmark feature of several primary psychotic disorders, it can also occur as a symptom in other mental health conditions such as bipolar disorder and post-traumatic stress disorder (PTSD). The severity, frequency, and duration of psychotic symptoms can vary greatly depending on the underlying cause and individual factors.

Stages of Psychosis

  1. Prodromal Phase- This is the initial stage, where early warning signs begin to emerge. Individuals may notice subtle shifts in their thinking, mood, or behavior. Common symptoms include increased anxiety, withdrawal from social interactions, difficulty concentrating, and a sense that thoughts are scattered or confusing. These signs are often overlooked or misattributed to stress or adolescence.
  2. Acute Phase- In the acute stage, psychotic symptoms become more pronounced and disruptive. The person may experience vivid hallucinations, persistent delusions, and markedly disorganized thoughts or speech. These symptoms can severely impair functioning and may lead to hospitalization or intensive care.
  3. Recovery Phase- Recovery typically begins once treatment is initiated or the underlying cause is addressed. Symptoms gradually diminish in intensity, and individuals begin to regain a sense of clarity and stability. Ongoing therapeutic support, medication adherence, and relapse prevention strategies are essential to sustaining recovery and rebuilding functional capacity.

Types of Psychosis

  • Brief Psychotic Disorder- A sudden onset of psychotic symptoms that lasts for less than one month, typically triggered by a highly stressful or traumatic event. The individual usually makes a full recovery once the episode resolves.
  • Bipolar Disorder with Psychotic Features- Psychosis may occur during manic or depressive episodes in bipolar disorder. During mania, it may involve delusions of grandeur or invincibility; in depressive phases, it may involve delusions of guilt or worthlessness.
  • Schizoaffective Disorder- A complex condition that features a combination of psychotic symptoms (such as hallucinations or delusions) and mood disorder episodes (either depressive or manic). It is distinguished by the persistence of psychotic features even in the absence of mood symptoms.
  • Schizophreniform Disorder- This condition includes symptoms similar to schizophrenia but lasts between one and six months. If symptoms persist beyond six months, a diagnosis of schizophrenia may be considered.
  • Substance/Medication-Induced Psychotic Disorder- Psychosis may be triggered by substance use, withdrawal, or adverse reactions to certain medications. Common substances linked to psychosis include cannabis, amphetamines, hallucinogens, and stimulants. Early identification and cessation of the substance often lead to symptom resolution.
  • Postpartum Psychosis- A rare but severe psychiatric condition that occurs shortly after childbirth. Symptoms may include hallucinations, delusions, mood swings, and severe confusion. It constitutes a medical emergency and requires immediate intervention to ensure the safety of both mother and child.

Causes of Psychosis

  • Genetic Predisposition- A family history of psychotic disorders significantly increases the likelihood of developing psychosis. Although genetics alone do not determine the onset, they contribute to an individual’s vulnerability. Inherited traits can affect how a person responds to environmental stressors, potentially influencing the onset, intensity, and course of psychotic symptoms.
  • Neurobiological Factors- Alterations in brain chemistry and structure are strongly associated with psychotic experiences. Specifically, dysregulation of neurotransmitters—particularly dopamine—plays a central role. Excess dopamine activity in certain brain pathways is linked to hallucinations and delusions. Additionally, abnormalities in brain regions such as the prefrontal cortex and temporal lobes may contribute to disorganized thinking and impaired judgment.
  • Psychosocial and Environmental Stressors- Exposure to chronic stress, especially during formative years, is a significant risk factor. Traumatic experiences such as physical or emotional abuse, neglect, or the loss of a caregiver can disrupt emotional development and increase susceptibility. High-stress environments can also act as a trigger for psychotic episodes in genetically predisposed individuals.
  • Substance Use- The use of psychoactive substances such as cannabis, cocaine, LSD, and methamphetamines can induce psychotic symptoms, particularly in vulnerable individuals or when use begins during adolescence. Repeated or high-dose exposure may not only trigger acute psychosis but also contribute to the development of chronic psychotic disorders.
  • Medical and Neurological Conditions- Psychosis can also be secondary to underlying medical issues. These include infections affecting the brain (e.g., encephalitis), autoimmune disorders, metabolic imbalances, brain injuries, and neurodegenerative conditions such as dementia. In such cases, identifying and treating the primary medical condition is crucial to resolving psychotic symptoms.

Signs and Symptoms of Psychosis 

  • Hallucinations (hearing, seeing, smelling, or feeling things that are not present)
  • Delusions (false, fixed beliefs not based in reality, such as paranoia or grandiosity)
  • Disorganized speech (incoherent, rapid, or tangential speech patterns)
  • Disorganized behavior (unpredictable or inappropriate actions)
  • Diminished emotional expression (flat affect)
  • Social withdrawal or lack of interest in relationships
  • Low motivation and difficulty initiating tasks
  • Reduced verbal communication and non-verbal expressions
  • Anhedonia (inability to feel pleasure)
  • Problems with memory, attention, or abstract thinking
  • Difficulty making decisions or following instructions
  • Anxiety, mood swings, irritability, and inappropriate emotional responses
  • Impaired insight into one’s condition

Treatment for Psychosis

  • Psychotherapy- Psychotherapy provides a structured and supportive space to help individuals make sense of confusing or distressing experiences. It helps address feelings of fear, alienation, or mistrust, which are common during psychotic episodes. Therapy also aids in rebuilding identity and improving interpersonal relationships, contributing to emotional recovery and overall well-being.
  • Cognitive Behavioural Therapy (CBT)- CBT is particularly effective for managing persistent psychotic symptoms such as delusional beliefs or hallucinations. This therapeutic approach helps individuals develop insight into their experiences, challenge irrational thoughts, and adopt healthier coping mechanisms. CBT also promotes emotional regulation and reduces distress associated with psychotic episodes.
  • Antipsychotic Medication- Pharmacological treatment plays a central role in managing psychosis. Antipsychotic medications target neurotransmitter systems—primarily dopamine—to reduce hallucinations, delusions, and disorganized thinking. Early and consistent use of these medications can significantly shorten the duration of untreated psychosis and enhance long-term recovery. Ongoing monitoring for side effects is essential to ensure treatment adherence.

Though psychosis can be deeply disorienting, it is a treatable condition. With timely intervention, supportive therapy, and consistent care, individuals can regain clarity, rebuild their lives, and move forward with resilience and hope.
