Bipolar Disorder Midterm 2 Review -
Thursday Jan 30, 2025
Bipolar I and Bipolar II
Symptoms of Manic ep:
Mood changes
Long period of feeling “high”, overly happy/outgoing mood
Irritable mood agitation, jumpy, wired
Behavioral changes:
Very fast talking
Easily distracted
Increase goal-directed activities
restless/not sleeping
Impulsive (high risk behaviors)
Depression/Depressive Episodes:
Mood changes:
Long period of feeling worried/empty
Loss of interest in activities
Behavioral Changes
Tired “slowed down”
Problems concentrating
Thinking of death/suicide - attempting suicide
Bipolar 1-
Less Mania More Depressed
It happens more in males
At least ONE manic ep that lasts for 7 days
Bipolar II-
Depressive ep shifting
Hypomanic eps
NO FULL BLOWN manic/mixed eps.
BP-NOS
Symptoms of illness but NOT ENOUGH to meet specific criteria for BP I OR II
Cyclothymic Disorder, Cyclothymia
Mild form of BP
At least 2 years of hypomania eps
Does not meet specific criteria
Rapid Cycling Bipolar Disorder
When a person has four or more eps of mj depression, hypomania, mixed sympt within a year.
MANIA STATES:
Hypmania
Acute Mania- transition delusion
Delusional Maia
Delerious Mania
Schizoaffective Disorder vs. Bipolar
BOTH have PSYCHOTIC symptoms:
Hallucination
Delusion
Incoherence
Schizo is better tolerated by families
“Unipolar” manic
Depressive is dominant in FEMALES
Mania is dominant in MALES
The difference between major depression and depressive eps is the fluctuation/shifts
Risks of Bipolar Disorder:
Spending sprees/business ventures
Hypersexuality
Run in w/ law
Accidents-speed limits
Poor relationships
Suicide 10-20%
Atman self-rating mania scale - designed to assess the presence/severity of manic symptoms.
Can be used as a psycho-educational tool to help patients recognize and monitor their own symptoms.
Lecture 8:
Changes in ppl w/ Bipolar Disorder
Increased ventricle size
Corpus Callosum
Decreased white matter associated w/ suicidality
Whiter matter lays in between gray matter.
Hyperintensity- signals areas of cell death

Left side of brain→ more literal, language, analytical thinking
Right side→ involves more motor control
Amygdala– helps u determine/read facial expressions
Right amygdala activity
Both at-risk and bipolar groups have higher amygdala activity

Gout - disease of kings
Henry the VIII– had gout, diabetes, obesity, 6 wives, 2 beheadings
Purines (nitrogenous bases)
What causes GOUT?
Purines (meats)
Fructose (sugar)
Lithium: → Mood Stabilizer
Discovered in 1817
-7UP lithiated LEMON SODA
1929-1948
Lower suicide rate, crime and homicide rates
1949 John Cade
Published a paper on lithium’s calming effects in bipolar patients.
Injected pee from patients into guinea pigs
Pee from Psychotic patient injected into pig:
Pig got sick and didn’t act normal
Non- Psychotic patient:
Pig was fine
Uric Acid crystals– were blocking the needle
The avg level of uric acid → HIGHER in those having manic ep.
Hypothesis: Higher levels of uric acid = more risk of manic episodes.
Ex: more sugar u drink per day → INCREASED uric acid
URIC ACID→ INCREASE INFLAMMATION
Glutamate– #1 excitatory neuron (causes neurons to fire)
Too excitable can kill neurons surrounding
Causes the amygdala and hippocampus to be excitable
Too much Dopamine in the frontal cortex → causes psychosis
Amphetamine/Cocaine
Drug increases dopamine-> psychotix
Antagonists- Drugs that blogs receptors
Can block psychosis if blocking the right receptors.
Dyskinesias
Caused by long-term use of antipsychotics
Corticoid steroids–
Hyper-exitation → leads to oxygen radicals
Neuron death- leads to more exitation
Inflammation → increase glutame → increased excitation→ cell death —-(cycle back)

Bipola Disorder Review
Enlarged ventricles
Mania
Comorbidities govt/ metabolic disorder
Amygdala & ParaHipgy Hyperactive
Phases Mania Depression Rapid Cycling
Lithium
White matter - axonal projections
Cortex Grey matter thinning
Mania→ high uric acid = purines
Glutamate- #1 Excitatory NT
Dopamine - Psychosis - frontal cortex
More neurons firing
Drug that treats too much glutamine→ anticonvulsive / antiepileptic
Eating a diet high in purines —> MORE uric acid (greater lvls in men)
MORE URIC ACID—> Inflammation —> Cytokines that Call the Immune Response → Excitation = Glutamate —> more neurons firing & Dying
Neuron Death
Loss of Brain Tissue
(Insert notes from lec)
Hyper (methylation)– stop signs
More methylation– gene is expressed more protein
Ex: blonde hair gene – more blonde (expressed)
Discordant—> 1 twin HAS it one DOESN'T
Tues Feb 18th, 2025
Drugs used to treat depression→ Reuptake blockers
Increases serotonin by keeping transmitters longer
More methylation— less protection (less product)
Less methylation→ more expression
COX 2– Inflammatory (bad)
Rapid Cycling
Dangerous symptoms
Fast shifts between high and lows
Patients are more at risk for self-harm
Estrogen – protective of inflammatory
