Symptoms may include:
Hallucinations: Sensory experiences in the absence of a sensory stimulus, which can occur in any sensory modality (auditory, visual, gustatory, olfactory, somatic/tactile). That is, the person, hears, sees, tastes, smells, or feels in their body or on their skin, things that aren’t there. Common symptoms include: hearing single or multiple voices (simple or complex, abusive, neutral and even soothing), visual hallucinations (seeing people or objects that others do not) body sensations or feelings that are new and strange (electrical charges or small bugs crawling over a person’s limbs), tasting/smelling things that others do not (often unpleasant, but not exclusively so).
Delusions: Often referred to as fixed, false beliefs. The person believes, with full conviction, in something that most other people don’t believe. Common delusions include: persecutory delusions (false belief that someone or something is trying to trick, torment, spy or follow them), referential delusions (television, music or signs in the world refer specifically to them), grandiose delusions (believing they have special powers or abilities, or are a famous or very important person/being, such as a religious figure, musician, actor).
Cognitive disorganization: Speech and writing become disorganized and/or tangential. Individuals may formulate connections between words that seem illogical and/or they may have difficulty following conversations.
Negative Symptoms: A diminishing or absence of usually present emotions or behavior. Common negative symptoms include flattened affect (decreased expression of emotion in face, vocal intonations, and bodily gestures), avolition (diminished volition or will to initiate or sustain goal directed activities), anhedonia (decreased interest or pleasure in previously enjoyed activities); decreased emotional experience (feeling emotionally deadened or flat),
It is important to keep in mind that any given individual with psychosis may experience all, or only a few, of the above symptoms, and may experience them in a different way than we have described. The intensity and impact of particular symptoms can also vary enormously from individual to individual.
