PSYB65H3 Lecture Notes - Lecture 6: Frontal Lobe, Dopamine Receptor, Serotonin
Document Summary
Most commonly associated with hallucinations (auditory: hear someone talking to them) & delusions (weird thoughts) Sudden age of onset: 30 years (after this age quite rare) Predictors: but there are early indications or predictors of it in childhood (usually don"t have warm relationships with people) Poor performance on tests that test frontal lobe function: deficits in memory tests (verbal or non-verbal, other tests show that they"re completely normal. Take into account that these people have been on antipsychotic medication for a long time. So this could account for memory problems: enlarged ventricles and lighter brain weight, this could also be an effect of the medication. 1% of the population is schizophrenia (1 out of 100 people have it) If you look at the immediate family - 10 to 15% have it, not 1% - so there could be a genetic component.
