Psychosis is a mental state defined by a significant disconnection from reality, which manifests as severe disturbances in a person’s thinking, emotions, and behavior. It is a collection of symptoms, not a diagnosis itself, that can be a feature of various mental health conditions like schizophrenia or bipolar disorder, or result from medical issues or substance use. During a psychotic episode, an individual often struggles to distinguish between what is real and what is not, leading to unusual or strange ideas and perceptions. This experience can be extremely distressing and alarming for the person affected, making a timely response important. Psychosis generally follows a progression that can be understood in three distinct stages.
Stage 1: The Prodromal Phase
The first stage is known as the prodromal phase, which represents a period of gradual, non-specific changes that occur before the full experience of psychosis. This phase can last for weeks, months, or even years, and its symptoms are often so subtle that they are only recognized in hindsight. The changes involve a decline across several areas of functioning, which may initially be mistaken for typical adolescent behavior or a reaction to stress.
A common manifestation is a functional decline, such as dropping grades in school or decreased performance at work. Individuals frequently begin to withdraw socially, preferring solitude over spending time with friends and family. Mood changes are also prominent, including increased anxiety, irritability, or the onset of a depressed mood.
Sleep disturbances are a frequent complaint during this time, alongside a general lack of energy and motivation. While not yet full delusions, a person may start to develop vague, unusual thoughts, such as a growing suspiciousness or a sense of being disconnected from their surroundings. These shifts in perception and thinking are typically mild.
Stage 2: The Acute Phase
The prodromal phase transitions into the acute phase, which is when the characteristic symptoms of psychosis emerge with full intensity. This stage is defined by the presence of “positive symptoms,” which are experiences that are added to a person’s normal mental functioning. It is during this time that a person’s disconnection from reality is most profound and noticeable.
One hallmark positive symptom is hallucinations, which are sensory experiences that occur without any external stimulus. These can affect any of the five senses, though auditory hallucinations, such as hearing voices, are the most common. The person may also experience visual, tactile, or olfactory hallucinations that feel completely real to them.
Another core symptom is the presence of delusions, which are fixed, false beliefs that are firmly held despite clear evidence to the contrary. Common types include persecutory delusions, where the person believes they are being harmed or conspired against, or grandiose delusions, where they believe they possess special powers or importance.
The acute phase also involves disorganized thinking, which is apparent through incoherent or rapid speech patterns that jump illogically from one topic to another. Disorganized behavior, such as unpredictable agitation or catatonia, can also occur, making immediate intervention necessary to manage the severe disruption to daily life.
Stage 3: The Recovery and Residual Phase
Following the peak intensity of the acute phase, the individual enters the recovery and residual phase, where the focus shifts toward stabilization and long-term management. With appropriate treatment, the acute positive symptoms, like severe hallucinations and delusions, typically begin to diminish in intensity and frequency. The person slowly starts to regain insight, meaning they are better able to recognize that their recent experiences were not real, though this realization can sometimes cause emotional distress.
Even as the dramatic positive symptoms subside, a different set of challenges, known as “negative symptoms,” often become more prominent. Negative symptoms represent a reduction or loss of normal functions, which can include a lack of motivation, a flattened emotional expression (blunted affect), or a loss of interest or pleasure in activities (anhedonia). These symptoms tend to be the most persistent and can significantly impact the person’s functional recovery and social reintegration.
Ongoing treatment, typically involving a combination of antipsychotic medication and psychotherapies, is important to manage these residual symptoms and prevent a relapse. The goal of this phase is functional adaptation, where the individual works to resume educational, occupational, and social roles, often requiring therapeutic support to build coping skills. While many people successfully recover, some residual symptoms or functional impairments may remain, highlighting the need for consistent, long-term care.
