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.
A schizophrenic episode can last days or weeks, and in rare cases, months, says Dr. D'Souza. Some people may experience only one or two schizophrenic episodes in their lifetime, whereas for others the episodes may come and go in phases.
Research suggests schizophrenia may be caused by a change in the level of 2 neurotransmitters: dopamine and serotonin. Some studies indicate an imbalance between the 2 may be the basis of the problem. Others have found a change in the body's sensitivity to the neurotransmitters is part of the cause of schizophrenia.
Loss of interest in activities and other things. Mood swings and outbursts. Emotional numbness. Significant changes in daily patterns, such as sleep, appetite and eating, or self-care.
The last stage is the residual phase of schizophrenia. In this phase, you're starting to recover, but still have some symptoms.
This is a psychotic break — when someone loses touch with reality, experiencing delusions (false beliefs) or hallucinations (seeing or hearing things that are not there) and what's called “disorganized” speech.
Schizophrenia usually involves delusions (false beliefs), hallucinations (seeing or hearing things that don't exist), unusual physical behavior, and disorganized thinking and speech. It is common for people with schizophrenia to have paranoid thoughts or hear voices.
Early Warning Signs of Schizophrenia
One is that people with the disorder often don't realize they're ill, so they're unlikely to go to a doctor for help. Another issue is that many of the changes leading up to schizophrenia, called the prodrome, can mirror other normal life changes.
During a psychotic episode, a person's thoughts and perceptions are disrupted, and they may experience hallucinations, delusions, abnormal behavior, disorganized speech, and incoherence. A mental breakdown does not rule out the possibility of psychosis, but a psychotic break refers specifically to a psychotic episode.
It is possible to experience hallucinations while being aware that they aren't real. As with delusions, this would require a meta-awareness of the unreality of what appears to be a real experience.
Early warning signs of schizophrenia
In this early phase of schizophrenia, you may seem eccentric, unmotivated, emotionless, and reclusive to others. You may start to isolate yourself, begin neglecting your appearance, say peculiar things, and show a general indifference to life.
Those risk factors include genetic mutations you inherit from one or both parents, exposure to certain chemicals or substances, complications during pregnancy and recreational drug use. However, experts have yet to uncover any confirmed triggers or causes for this condition.
Social withdrawal
Schizophrenia can lead you to withdraw from socializing or that you isolate yourself in your home. This can be due to, for example, your hallucinations, thought disorders or lost social skills or fear of social contacts.
Although the majority of patients with schizophrenia are not actually violent, an increased tendency toward violent behaviors is known to be associated with schizophrenia. There are several factors to consider when identifying the subgroup of patients with schizophrenia who may commit violent or aggressive acts.
Borderline schizophrenia is held to be a valid entity that should be included in the DSM-III. It is a chronic illness that may be associated with many other symptoms but is best characterized by perceptual-cognitive abnormalities. It has a familial distribution and a genetic relationship with schizophrenia.
Auditory hallucinations, “hearing voices,” are the most common in schizophrenia and related disorders. Disorganized thinking and speech refer to thoughts and speech that are jumbled and/or do not make sense.
Schizophrenia can usually be diagnosed if: you've experienced 1 or more of the following symptoms most of the time for a month: delusions, hallucinations, hearing voices, incoherent speech, or negative symptoms, such as a flattening of emotions.
The peak age of onset of schizophrenia is 15 – 25 years in men and 20 – 30 years in women. It is often preceded by a prodromal phase of vague symptoms, some odd behaviours and a decline in functioning at school or work and interpersonally.
In most people with schizophrenia, symptoms generally start in the mid- to late 20s, though it can start later, up to the mid-30s. Schizophrenia is considered early onset when it starts before the age of 18. Onset of schizophrenia in children younger than age 13 is extremely rare.
