Schizophrenia is a mental disorder characterized by an inability to maintain normal thought processes and a lack of normal emotional responses. Around 50 million people worldwide have schizophrenia, which commonly involves auditory hallucinations, paranoid or bizarre delusions, and disorganized speech and thinking. Paranoid schizophrenia is the most common type, dominated by relatively stable delusions and hallucinations without prominent disturbances in affect, volition, or speech. Common paranoid symptoms include persecutory or referential delusions and threatening voices.

4. 
. Paranoid Schizophrenia
-Paranoid Schizophrenia is the most common type of Schizophrenia in most parts of the world. The clinical
picture is dominated by relatively stable, often paranoid, delusions, usually accompanied by hallucinations,
particularly of the auditory variety, and perceptual disturbances. Disturbances of affect, volition, and speech,
and catatonic symptoms, are not prominent.
. Examples of the most common paranoid symptoms are:
-delusions of persecution, reference, exalted birth, special mission, bodily change or jealousy
-hallucinatory voices that threaten the patient or give commands, or auditory hallucinations without verbal
form, such as whistling, humming or laughing
-hallucinations of smell or taste, or of sexual or other bodily sensations; visual hallucinations may occur but
are rarely predominant

5. Thought disorder may be obvious in acute states, but if so it does not prevent the typical delusions or
hallucinations from being described clearly. Affect is usually less blunted than in other varieties of
schizophrenia, but a minor degree on incongruity is common, as are mood disturbances such as irritability,
sudden anger, fearfulness, and suspicion. “Negative” symptoms such as blunting of affect and impaired
volition are often present but do not dominate the clinical picture.
