The peak age of onset of shcizophrenia is ________ for men and _________ for women.
|
15-25 years old for men
25-35 years for women schizophrenia occurs equally in men and women, all cultures and all ethnic groups studied |
|
|
Symptoms of schizophrenia can be classified as positive or negative. Describe the classification categories and name examples of symptoms in each.
|
Positive symptoms = things additional to expected behavior (delusions, hallucinations, agitation, talkativeness) ; these respond well to both traditional and atypical antipsychotic agents.
Negative symptoms = things missing from expected behavior (lack of motivation, social withdrawal, flattened affect, cognitive disturbances, poor grooming, impoverished speech content); these respond better to atypical (rather than typical) antipsychotic agents. |
|
|
Patients with [ positive / negative ] symptoms respond well to traditional and atypical antipsychotic agents whereas patients with [ positive / negative ] symptoms respond better to atypical than to traditional antipsychotics.
|
Positive symptoms = both typical and atypical
Negative symptoms = moreso to atypical |
|
|
Patients with [ positive / negative ] symptoms have more neuroanatomic and metabolic abnormalities than those with predominantly the other kind of symptoms.
|
Patients with NEGATIVE symptoms (lack of motivation, social withdrawal, flattened affect, cognitive disturbances, poor grooming, impoverished speech content) usually have more neuroanatomic and metabolic abnormalities
|
|
|
Schizophrenia ha three phases: prodromal, active and residual phase. Describe each.
|

ACTIVE PHASE: patient loses touch with reality. Disorders of perception, thought content, thought process, and form of thought occur during an acute psychotic episode. RESIDUAL PHASE: time between psychotic episodes where the patient is in touch with reality but does NOT behave normally. Typically characterized by negative symptoms. |

|
|
Anatomical neural pathology of someone with schizophrenia includes
A. abnormalities of the frontal lobes - how so? B. lateral and third ventricle size change - how so? C. limbic structure volume change - how so? |
A. abnormalities of the frontal lobes - DECREASED USE OF GLUCOSE IN FRONTAL LOBES UPON PET SCAN
B. lateral and third ventricle size change - ENLARGEMENT, ABNORMAL CEREBRAL SYMMETRY C. limbic structure volume change - DECREASED VOLUME OF LIMBIC STRUCTURES |
|
|
Which of the following is NOT implicated in neurotransmitter abnormalities present in schizophrenia?
A. ACh B. Dopamine C. Glutamate D. Serotonin |
NOT implicated in schizophrenia is : A. ACh
Excessive dopamine hypothesis of schizophrenia, Serotonin hyperactivity is (since hallucinogens that increase serotonin concentrations can cause psychotic symptoms), Glutamate is also implicated |
|
|
Psychotic disorders are ALL characterized at some point during their course by ...... Name other psychotic disorders besides schizophrenia.
|
a loss of touch with reality!
Brief psychotic disorder: psychotic symptoms lasting more than one day but less than one month. Schizophreniform disorder : psychotic and residual symptoms lasting 1-6 months Schizoaffective disorder : symptoms of a mood disorder plus psychotic symptoms Delusional disorder : fixed persistent delusions Shared psychotic disorder : development of delusions in a person in a close relationship with someone with delusional disorder |
