Paranoia is a mental disorder in which a person begins to see signs of conspiracy or danger in those around him or in current events. He becomes suspicious, often to the point of paranoia. A person suffering from this disease develops delusions of persecution, as well as excessive fears for his life and safety. Due to frequent experiences of panic, people suffering from paranoia experience disturbed sleep, hand tremors, and problems with speech and coordination of movements. Some patients with paranoia are also prone to excessive suspiciousness, delirium and phobias.
Paradoxically, this behavior is also typical for many healthy people, who are still prone to various types of suspicion. This to some extent protects them from the aggressive, unpleasant society in which they live. It is impossible to recognize paranoia in yourself or another person without a psychiatric examination and detailed diagnosis. However, paranoia can manifest itself without the participation of doctors. So, for example, if a person constantly finds differences in passers-by on the street, looks at them suspiciously, and contacts the investigative service or the police, then with a high degree of probability it can be argued that he has some kind of mental disorder, including paranoia.
