The five primary symptoms of psychosis are hallucinations, delusions, disorganized speech, disorganized behavior, and negative symptoms.
Hallucinations are defined as false sensory perceptions that are experienced in the absence of any external stimuli. Examples of hallucinations can include hearing voices, seeing visions, or feeling sensations that are not actually present.
Delusions are false beliefs that an individual holds despite evidence to the contrary. Delusions can be grandiose in nature, such as believing that one is a powerful figure or has special powers, or they can involve paranoid beliefs, such as believing that someone is out to get them.
Disorganized speech is characterized by tangential and circumstantial thinking that often makes it difficult for others to follow the conversation. This can be evidenced by frequent derailment of topics, incoherent speech, and changes in the volume, tempo, and tone of the person's speech.
Disorganized behavior is a symptom of psychosis that can manifest in a variety of ways. Examples include dressing inappropriately for the weather, neglecting hygiene, and engaging in purposeless and repetitive activities.
Negative symptoms are characterized by an absence of behavior or emotion. This can manifest as difficulty initiating or sustaining activities, reduced speech, and decreased emotional expression.
In addition to the five primary symptoms of psychosis, individuals may also experience cognitive symptoms such as difficulty with memory, focus, or decision making.
It is important to note that the symptoms of psychosis can vary significantly from person to person and may vary in severity over time.
