Thought Disorders Flashcards
Schizophrenia
A group of psychotic disorders that affect the perception of thought, the way language is spoken as well as how it is perceived, emotions, social behavior, and the ability to perceive reality
How does schizophrenia progress?
It is a chronic illness that worsens with time and with an eventual halt in the progression of the symptoms
** Only for elderly patients with schizophrenia has it been suggested that improvement might occur
Is there a standard treatment for schizophrenia?
No, treatment is so customized and unique that it can vary from one person to the next, as well as one episode of an individual to the next
Early Age Onset of Schizophrenia is usually associated with what?
18-25 years old
- More often male
- Poorer premorbid adjustment
- More structural brain abnormalities
- More prominent negative symptoms
* * The younger the patient is at the onset of schizophrenia, the more discouraging the prognosis
Later Age Onset of Schizophrenia is usually associated with what?
25-35 years old
- More female cases
- Less structural brain abnormalities
- Better outcomes
Which has a more favorable prognosis, an abrupt onset or a slow onset?
An abrupt onset
Characteristics of Schizophrenia
- Dependency
- Depressive symptoms
- Anxiety disorders
- Psychosis-Induced Polydipsia
Characteristics of Schizophrenia: Dependency
Very common characteristic, 75-85% schizophrenic client’s smoke. They tend to smoke 2-3 times more than the average smoker
Characteristics of Schizophrenia: Depressive Symptoms
Suicide is the leading cause of premature death and 20 times higher with schizophrenics than those of the general population
Characteristics of Schizophrenia: Anxiety Disorders
Significantly higher in those with schizophrenia than those in the general population
Characteristics of Schizophrenia: Psychosis Induced Polydipsia
Compulsive drinking of water (up to 4-10 L/day) seen in those with schizophrenia and severe mental illness. May result in severe hyponatremia, cerebral edema, and death
Diagnostic Criteria for Schizophrenia
The criteria for the diagnosis of schizophrenia includes a mixture of core (positive and/or negative) symptoms for a significant portion of a one month period but with continuous signs of disturbance persisting for at least 6 months
Types of Schizophrenia
- Disorganized
- Catatonic
- Paranoid
- Undifferentiated
- Residual
* * Recent research indicates that subtyping schizophrenia is not useful for predicting course of disease and subtypes may no longer be recognized by DSM
Disorganized Schizophrenia Onset
Before the age of 25, usually early to mid-teens
Characteristics of Disorganized Schizophrenia
- Chronic
- Behavior is aggressive and primitive
- Poor reality orientation
- Flat or incongruent affect
- POOR prognosis, usually institutionalized
- Hebephrenic
- Word salad, thought blocking, clang association
How would get a Disorganized Schizophrenic to communicate with you?
Parallel play
Catatonic Schizophrenia
Its essential feature is extreme abnormal motor behavior. They exhibit either extreme motor agitation or extreme psychomotor retardation
- Echolalia
- Echopraxia
Two Types of Catatonic Schizophrenia
- Catatonic stupor
2. Catatonic excitement
Catatonic Stupor
Characterized by extreme psychomotor retardation such as a pronounced decrease in spontaneous movements and activity
- May have mutism
- May have negativism (an apparent senseless resistance to all instructions or attempts to be moved)
- May have waxy flexibility
Catatonic Excitement
- Extreme psychomotor retardation
- Frenzied and purposeless movements accompanied by incoherent verbalizations and shouting
Why does a patient in catatonic excitement require urgent medical attention?
They require physical and medical control due to destructive and violent behavior to others. Excitement may cause them to injure themselves or collapse from exhaustion
Paranoid Schizophrenia Onset
Mid to late 20s-30s
Characteristics of Paranoid Schizophrenia
- Delusion of persecution or grandeur
- Hallucinations (usually auditory - most common)
- Usually centered on a single theme (hurt themselves, degrade themselves)
- Often have good social/occupational function with help
- Unable to trust
- They are guarded, apprehensive, and reserved
- Projection is the most common defense mechanism used
* * TRUST is very important with these patients
Undifferentiated Schizophrenia Onset
Begins early and has insidious onset (early to middle teens)
Characteristics of Undifferentiated Schizophrenia
- Psychosis with a mixture of positive and negative behaviors
- Active signs of disorder, but does not meet the criteria for a specific sub-schizophrenia
- Premorbid state is less predictable, and disability remains fairly stable, although persistent over time
Residual Schizophrenia
- Active phase symptoms (delusions, hallucinations, or disorganized speech) no longer exist, but at least 2 residual symptoms are present
- Residual symptoms include lack of initiative, social withdrawal, inability to work or study, vague or lack of content in speech, and magical thinking or odd beliefs
Phases of Schizophrenia
- Prodromal Phase
- Acute Phase
- Maintenance Phase
- Recovery Phase (Stabilization)
Prodromal Phase
- May appear in a month or a year before the first psychotic break
- Occurs in up to 80-90% of people before the acute phase
- Has early and late symptoms
Early Symptoms of Prodromal Phase
- More withdrawn, and have odd behavior (neglect personal hygiene/grooming)
- There is a lack of initiative, interests, or energy
- Blunted or inappropriate affect
- Speech may be characterized by unclear symbolism
Late Symptoms of Prodromal Phase
- Words and phrases may become indecipherable
Three Kinds of Symptoms in the Acute Phase
- Positive symptoms
- Negative symptoms
- Cognitive symptoms
Positive Symptoms of the Acute Phase
- Hallucinations
- Delusions
- Disorganized behavior
- Bizarre behavior
Negative Symptoms of the Acute Phase
- Blunted affect
- Alogia
- Avolation
- Anhedonia
Alogia
“Poverty of thought”
- Alogia is the inability to speak because of mental defect, mental confusion, or aphasia. It is a speech disturbance that can be seen in people with dementia. However, it is often associated with the negative symptoms of schizophrenia.
