Midterm Exam Study Guide Flashcards
LITHIUM
USES
- Lithium is the drug of choice for controlling acute manic episodes in patients with bipolar disorders AND for long-term prophylaxis for against recurrence for mania and/or depression. Gotta stabilize that mood fam.
- Reduced euphoria, hyperactivity, BUT does not cause sedation.
LITHIUM
DANGER
- DANGER DANGER: Because lithium is excreted by the kidneys, watch out for patients who have renal problems! If ya can’t piss it out, we in trouble.
- Dehydration will cause lithium retention , so increase fluids!
- Taking diuretics and drinking alcohol increases your serum lithium levels
LITHIUM
LEVELS
- Maintenance (What we should keep it around): 0.4 - 1.0 mEq/L
- What dose should we give: 900 to 1200 mg
- TOXICITY: Lithium levels must be kept under 1.5 mEq/L, levels above this can produce significant toxicity.
- So make sure, you gotta draw lithium blood levels to see how your body handles it!
LITHIUM
SIDE EFFECTS
- GI effects such as nausea, vomiting, abdominal bloating, and diarrhea.
- Tremor (Produce fine hand tremor)
- POLYURIA - You piss alot, like a bunch. Some patients almost 3 L a day.
- Renal Toxicity (Assess kidney function before treatment
- Goiter & Hypothyroidism
- Teratogenesis
- Use in lactation (Lithium goes into breast milk. So no no lithium guys)
- Rare chance of leukocytosis.
LITHIUM
TOXICITIES TABLE
SIDE EFFECTS OF
MOOD-STABILIZERS
(ANTI-CONVULSANTS)
- Anticonvulsant medications also are used as mood stabilizers.
- DANGER WILL ROBINSON, DANGER! Life-threatening side effect is Stevens-Johnson Syndrome (SJS), a severe rash which can affect the trunk OR mucous membranes can occur with anticonvulsants, esp. lamotrigine (Lamictal). Advance dose VERY SLOWLY:
- Patient needs regular blood draws to measure therapeutic levels. Can cause weight gain, sleepiness, N&V. May increase the risk of suicidal thoughts.
- -Hives, a rash, fever, or swollen glands.
- -Signs of Stevens-Johnson syndrome, which causes dangerous sores on the mucous membranes of the mouth, nose, genitals, and eyelids.
- -Confusion.
- -Slurred speech.
- -Nausea, vomiting, and diarrhea.
- -Trembling.
- -Increased thirst and increased need to urinate.
- -Weight gain in the first few months of use.
- -Drowsiness.
WHICH NEUROTRANSMITTERS
ARE AFFECTED BY
WHICH FAMILIES
OF ANTIDEPRESSANTS (SSRIs, SNRIs)
- SSRI’s (Guys its in the name!!) - Selective SEROTONIN reuptake inhibitors
- SNRI’s - SEROTONIN and NOREPINEPHRINE reuptake inhibitors
- NDRI’s- NOREPINEPHRINE and DOPAMINE reuptake inhibitors
- Monoamine Oxidase Inhibitors (TRICK QUESTION), it doesn’t affect a neurotransmitter directly. Monoamine oxidase is an enzyme responsible for breaking down the three (Serotonin, Norepinephrine, and Dopamine). SO by inhibiting the enzyme, we increase the levels of all three! Tho its a bad medication lol…
EPS and Metabolic Syndrome
Which drugs are they associated with
- EPS (Extrapyramidal Symptoms): rigidity, persistent muscle spasms, tremors, restlessness . Parkinsonianism is another type of EPS.
- Metabolic Syndrome: significant weight gain, increased blood sugar, increased triglycerides . This increases risk for CVD and diabetes . Some people get gynecomastia & galactorrhea. Patient’s weight, glucose levels, prolactin levels and lipid levels should be monitored regularly.
FOR ANTIPSYCHOTICS!!!
- First Gen Antipsychs: Causes EPS
- Second Gen Antipsychs: Metabolic syndrome AND a little bit of EPS as well!!

WHAT IS
ANXIETY
Anxiety and depression are often two sides of the same coin
A feeling of worry, nervousness, or unease, typically about an imminent event or something with an uncertain outcome. BASICALLY me before every exam
GAD (Generalized Anxiety Disorders)
Experiences excessive or unreasonable worry or apprehension.
- Patients have great difficulty controlling their anxiety. You basically worry about everything- Help
- Medications: Include Benzos (SHORT TERM ONLY!), Busiprone, and Antidepressants for long term care (SSRI or SNRI)
PANIC DISORDER
Pt. who have recurrent panic attacks or worried about having panic attacks
A panic attack is an abrupt surge of intense fear or discomfort that peaks at 10 mins. (FEELS like you having a heart attack)
Medications: SSRI and SNRI’s. Benzo’s to immediately reduce somatic symptoms until the antidepressants start working (So short term!)
AGORAPHOBIA
Agoraphobia - Anxiety triggered by real life situations or anticipated exposure such as open areas, small areas, public transportations
Can start panic like symptoms
Social phobia-Fear of social or performance situations in which embarrassment may occur, such as public speaking, going to parties.
Specific phobias
- Animal type: snakes, insects, etc. (childhood onset)
- Natural environment type: heights, water, storms (childhood onset)
- Blood, injection, injury type (familial, strong vasovagal reaction)
- Situational type: airplanes, elevator (bimodal peaks in childhood & in 20’s)
- Other: fear of choking, vomiting, illness
Medications: ALL PHOBIAS TREAT WITH SSRIS. Can give clonidine or propranolol before social situations. Also, cognitive behavioral therapy and systematic desensitization really helps :)
OCD
OBSESSVIE COMPULSIVE DISORDER
A common, chronic and long-lasting disorder in which a person has uncontrollable, reoccurring thoughts (obsessions) and behaviors (compulsions) that he or she feels the urge to repeat over and over.
Compulsions are rituals or repetitive behaviors that MUST be done for that individual to function.
MEDS:
SSRIs such as
fluoxetine (Prozac)
sertraline (Zoloft)
fluvoxamine (Luvox)
paroxetine (paxil)
PTSD
(Post traumatic stress disorder)
A disorder in which a person has difficulty recovering after experiencing or witnessing a terrifying event. This is usually associated with War vets or sexual trauma.
First line treatment for PTSD: SSRIs
Paroxetine, sertraline and fluoxetine
Secondline treatmetns: Tricyclic antidepressants and monoamine oxidase inhibitors
Trazadone to help sleep. Benzo’s for short term anxiety (Risk of dependence). Can give clonidine or propranolol. Finally, atypical antipsychotics such as olanzapine, risperidone, and quetiapine.
BIPOLAR DISORDER
- Bipolar I: Manic & depressed symptoms are present Most patients are depressed most of the time (More common in men)
- Bipolar II: Hypomania and depression (more common in females)
- Cyclothymic Disorder: The “lite” version of Bipolar II
BIPOLAR DISORDER
SIGNS & SYMPTOMS
MANIA
DIGFAST
- *D**istractibility
- *I**nsomnia (decreased need for sleep)
- *G**randiosity
- *F**light of ideas or racing thoughts
- *A**gitation
- *S**peech pressured, talkative
- *T**aking risks without regard for consequences
BIPOLAR DISORDER
KEY CONCEPTS
& DRUGS
- *Manic people like to be manic; depressed people don’t like to be depressed.** This affects motivation for treatment
- Mania is euphoric mood
Medications:
Antidepressants:
SSRIs (Prozac),
SNRIs (Effexor),
NDRIs (Wellbutrin),
tricyclic antidepressants (Trazodone),
MAOIs (Emsam)
Lithium for BIPOLAR Disorders. Help stabilize mood.
SCHIZOPHRENIA
- a long-term mental disorder of a type involving a breakdown in the relation between thought, emotion, and behavior, leading to faulty perception, inappropriate actions and feelings, withdrawal from reality and personal relationships into fantasy and delusion, and a sense of mental fragmentation.
- Delusions
- Hallucinations
- Disorganized speech
- Disorganized catatonic behavior
- Psychotic symptoms more pronounced and disruptive than in other psychotic disorders
- Schizophrenia does NOT mean split personality or multiple personality
- There are 2 types of symptoms seen in schizophrenia: negative and positive.
SCHIZOPHRENIA
POSITIVE SYMPTOMS
- caused by excessive dopamine in mesolimbic tract; Type I: symptoms are an embellishment of normal cognition and perception…symptoms are additional…believed to be a result of elevated dopamine levels affecting limbic areas of the brain
- Abnormal thoughts, Agitation, Bizarre behavior, Delusions, Excitement, Feelings of persecution, Grandiosity, Hallucinations, Hostility, Illusions, Insomnia, Suspiciousness
SCHIZOPHRENIA
NEGATIVE SYMPTOMS
- caused by too little dopamine in mesocortical tract; Type II: symptoms are essentially an absence or diminution of normal cognition and perception (ex: lack of energy)..Type II is related in part to hypodopaminergic process.
- Alogia (Poverty of speech), Anergia (lack of energy), Asocial behavior, Attention deficits, Avolition (decrease in the motivation to initiate and perform self-directed purposeful activities), Blunted affect (reduction in the intensity of an individual’s emotional response), Communication difficulties, Difficulty with abstractions, Passive social withdrawal, Poor grooming, hygiene, andt rapport
- FGA’s target positive symptoms, but don’t do much for negative symptoms. SGA’s target both types of symptoms.
- Symptoms of schizophrenia, such as agitation and hallucinations, can diminish within 1-2 weeks. Delusions can diminish within a few weeks . The average patient can expect only a 30-50% reduction in symptoms with treatment. If the patient stops taking meds, the symptoms will return.
- Medications: FGA, SGA, and last resort is clozapine.
TBI
TRAUMATIC BRAIN INJURY
- Disruption of normal brain function that occurs when the skull is struck, suddenly thrust out of position, or penetrated
- Symptoms may appear right away or may not be present until days or weeks or months after the injury
- TBI can affect a single, specific region of the brain (focal injury), be distributed throughout the brain (diffuse injury), or both
- Open wound injury: BAM a bullet to my head, or a pole
- Close Wound Injury: BAM I fell and hit the concrete (No penetration of the skull)
- Deceleration Injury: Shaken Baby syndrome. Occurs with differential movement of the skull and the brain when the head is struck
- BASED on loss of consciousness of how severe it is
- Mild: Loss of consciousness under 30 mins
- Moderate: More than 30 but less than 24 hours
- Severe: Shit…. Alot lol. Over 24 hours of no consciousness
- Always, look for risk for suicide!! Chance increases and substance abuse
- NO MEDICATIONS FOR TBI!!
