Psychotic disorders include schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, delusional disorder, shared psychotic disorder, substance-induced psychotic disorder, and paraphrenia.
Signs and symptoms of schizophrenia include false perceptions called hallucinations. Auditory hallucinations of voices are the most common hallucinations in schizophrenia, but affected individuals can also experience hallucinations of visions, smells, or touch (tactile) sensations.
The most common psychotic disorder is schizophrenia. This illness causes behavior changes, delusions and hallucinations that last longer than six months and affect social interaction, school and work.
Residual Schizophrenia
This specific type is characterized by when an individual doesn't display positive symptoms of paranoid schizophrenia (hallucinations, delusional thinking), although they still have the negative symptoms or more mild schizophrenia symptoms (no expression of emotions, strange speech).
Although schizophrenia can occur at any age, the average age of onset tends to be in the late teens to the early 20s for men, and the late 20s to early 30s for women. It is uncommon for schizophrenia to be diagnosed in a person younger than 12 or older than 40.
Of those, the three most common diagnoses are anxiety disorders, depression and post-traumatic stress disorder (PTSD). These three conditions make up around 30 percent of all diagnoses of mental illness in America.
The exact causes of schizophrenia are unknown. Research suggests a combination of physical, genetic, psychological and environmental factors can make a person more likely to develop the condition. Some people may be prone to schizophrenia, and a stressful or emotional life event might trigger a psychotic episode.
People with schizophrenia experience psychosis, which means they can have serious problems with thinking clearly, emotions, and knowing what is real and what is not. This can include hearing or seeing things that are not there (hallucinations), and having very strange beliefs that are abnormal or not true (delusions).
Schizophrenia involves a range of problems with thinking (cognition), behavior and emotions. Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized speech, and reflect an impaired ability to function.
Personality disorders such as antisocial, borderline, histrionic, narcissistic, avoidant, dependent and obsessive-compulsive types have been detected in one third to one half of schizophrenia patients (Nielsen, Hewitt & Habke, 1997; Solano & Chavez, 2000).
Individuals with Borderline Personality Disorder (BPDs) become overwhelmed and incapacitated by the intensity of their emotions, whether it is joy and elation or depression, anxiety, and rage. They are unable to manage these intense emotions.
How are personality disorders treated? Personality disorders are some of the most difficult disorders to treat in psychiatry. This is mainly because people with personality disorders don't think their behavior is problematic, so they don't often seek treatment.
Behavioral warning signs for psychosis include: Suspiciousness, paranoid ideas, or uneasiness with others. Trouble thinking clearly and logically. Withdrawing socially and spending a lot more time alone.
Psychosis can also be triggered by traumatic experiences, stress, or physical conditions, such as Parkinson's disease, a brain tumour, or as a result of drug misuse or alcohol misuse. How often a psychotic episode occurs and how long it lasts can depend on the underlying cause.
The symptoms of schizophrenia are usually classified into: positive symptoms – any change in behaviour or thoughts, such as hallucinations or delusions. negative symptoms – where people appear to withdraw from the world around then, take no interest in everyday social interactions, and often appear emotionless and flat.
Unfortunately, most people with schizophrenia are unaware that their symptoms are warning signs of a mental disorder. Their lives may be unraveling, yet they may believe that their experiences are normal. Or they may feel that they're blessed or cursed with special insights that others can't see.
