Paranoid delusions are false beliefs where a person feels they are being targeted, harmed, or persecuted by others. These beliefs are not based on reality and can lead to significant distress and dysfunction in daily life. Individuals may think that people are plotting against them or that they are under constant surveillance. These delusions can occur in various mental health conditions, such as schizophrenia or delusional disorder. Treatment often involves therapy and medication to help manage symptoms and improve the individual's quality of life. Understanding and support from loved ones can also be crucial in the recovery process.
