Common symptoms of psychosis include: Delusions: False beliefs that are firmly held, despite evidence to the contrary. Delusions can involve a wide range of themes, such as paranoia (believing others are plotting against you) or grandiosity (believing you have exceptional abilities or importance). Hallucinations: Perceiving things that are not actually present. Auditory hallucinations (hearing voices) are the most common type, but hallucinations can also affect other senses, such as seeing, smelling, tasting, or feeling things that are not there. Disorganized thinking: Individuals with psychosis may struggle to organize their thoughts and have difficulty expressing themselves coherently. Their speech may become incoherent or fragmented, making it hard to follow their conversations. Disrupted emotions: People experiencing psychosis can display intense and unpredictable emotional responses. They may exhibit a flat affect (reduced emotional expression) or inappropriate emotional reactions to situations. Impaired functioning: Psychosis can significantly impact an individual's ability to carry out daily activities, maintain relationships, or fulfill responsibilities at work or school.
