6 Types of Schizophrenia Disorganized Schizophrenia Disorganized Schizophrenia Catatonic Schizophrenia Catatonic Schizophrenia Paranoid Schizophrenia Paranoid Schizophrenia

7 Brain and Schizophrenia Larger than normal lateral ventricles – part of the ventricular system; contain cerebrospinal fluid Larger than normal lateral ventricles – part of the ventricular system; contain cerebrospinal fluid

8 Causes of Schizophrenia: Genetics Twin studies have shown that tendency for both monozygotic twins to develop schizophrenia is between 30 to 50%; the tendency for dizygotic twins and siblings to develop schizophrenia is 15% Twin studies have shown that tendency for both monozygotic twins to develop schizophrenia is between 30 to 50%; the tendency for dizygotic twins and siblings to develop schizophrenia is 15% Adoption Studies – 13% of biological relatives of adoptees with schizophrenia had the disease, but only 2% of biological relatives of normal adoptees had schizophrenia Adoption Studies – 13% of biological relatives of adoptees with schizophrenia had the disease, but only 2% of biological relatives of normal adoptees had schizophrenia

9 Causes of Schizophrenia: Environment Family Stress Family Stress Poor social interactions Poor social interactions Infections or viruses at an early age Infections or viruses at an early age Trauma at an early age Trauma at an early age Genetic makeup combines with non- genetic factors to cause schizophrenia Genetic makeup combines with non- genetic factors to cause schizophrenia

10 Causes of Schizophrenia: Neurotransmitters Dopamine Theory – schizophrenia caused by an overactive dopamine system in the brain; dopamine is a neurotransmitter that allows nerve cells in the brain to send messages to each other; dopamine imbalance may affect the way a person’s brain can react to stimuli Dopamine Theory – schizophrenia caused by an overactive dopamine system in the brain; dopamine is a neurotransmitter that allows nerve cells in the brain to send messages to each other; dopamine imbalance may affect the way a person’s brain can react to stimuli Many drugs for schizophrenia block dopamine receptors Many drugs for schizophrenia block dopamine receptors

11 Schizophrenia: Medication Antipsychotic medications – drugs do not cure disease, but reduce symptoms Antipsychotic medications – drugs do not cure disease, but reduce symptoms Some drugs have Parkinson’s Disease- like side effects Some drugs have Parkinson’s Disease- like side effects Counseling also helps Counseling also helps

12 Bipolar Disorder Characterized by changes in mood, behavior, and energy levels Characterized by changes in mood, behavior, and energy levels Affects approximately 1.2% of the population Affects approximately 1.2% of the population First episode often occurs in adolescence and can be triggered by a traumatic event; some people are symptom-free in between episodes First episode often occurs in adolescence and can be triggered by a traumatic event; some people are symptom-free in between episodes

13 Symptoms: Mania phase Abnormally elevated mood Abnormally elevated mood Inflated self-esteem Inflated self-esteem Reduced need for sleep Reduced need for sleep Excessive talkativeness Excessive talkativeness Racing thoughts Racing thoughts Distractibility Distractibility Activities done to excess Activities done to excess Pursuit of risky behavior or activities Pursuit of risky behavior or activities

14 Symptoms: Depression Phase Mania can quickly and without warning change to depression/sadness Mania can quickly and without warning change to depression/sadness Loss of interest Loss of interest Changes in appetite – weight gain/loss Changes in appetite – weight gain/loss Changes in sleep patterns Changes in sleep patterns Agitation Agitation Loss of energy Loss of energy Trouble concentrating/thinking Trouble concentrating/thinking Repeated thoughts of suicide/death Repeated thoughts of suicide/death

15 Accompanying Symptoms Psychosis Psychosis Delusions Delusions

16 Bipolar Disorder and the Brain Examination of brain tissue after people with BD have died Examination of brain tissue after people with BD have died Brain imaging Brain imaging New theory – mitochondrial malfunction New theory – mitochondrial malfunction Mitochondria – vital organelle for energy production Mitochondria – vital organelle for energy production 2000 – Kato, University of Tokyo – based on abnormal brain energy metabolism in bipolar patients measured by brain scans and mitochondrial depletion in autopsied bipolar brains; searched for mutant mitochondrial DNA – two suspect genes 2000 – Kato, University of Tokyo – based on abnormal brain energy metabolism in bipolar patients measured by brain scans and mitochondrial depletion in autopsied bipolar brains; searched for mutant mitochondrial DNA – two suspect genes March 2004, Archives of General Psychiatry, Christine Konradi - Harvard and McLean Hospital - studied brain tissue in hippocampus and found expression of genes that coded for mitochondrial proteins in bipolar patients decreased March 2004, Archives of General Psychiatry, Christine Konradi - Harvard and McLean Hospital - studied brain tissue in hippocampus and found expression of genes that coded for mitochondrial proteins in bipolar patients decreased

17 Famous People with BD Abraham Lincoln and Theodore Roosevelt Abraham Lincoln and Theodore Roosevelt George Handel, Robert Schumann, Ludwig van Beethoven George Handel, Robert Schumann, Ludwig van Beethoven Leo Tolstoy, Virginia Woolf, Ernest Hemingway, Charles Dickens Leo Tolstoy, Virginia Woolf, Ernest Hemingway, Charles Dickens Sir Isaac Newton Sir Isaac Newton Patty Duke, Linda Hamilton, Jean- Claude van Damme Patty Duke, Linda Hamilton, Jean- Claude van Damme
