what does serotonin do and what is the precursor
Neurotransmitter. Precursor is tryptophan found in protein foods. Sleep, appetite, pain aggression libido, hormones
what does norepinephrine do and what is the precursor
Neurotransmitter. Precursor is dopamine. Arousal, Fight or Flight, Mood
what does dopamine do and what is the precursor
Neurotransmitter. Precursor is phenylalanine found in protein foods. Fine muscle movement, emotions-thinking, hypothalamus to release hormones, pleasure response
what does histmaine do
Neurotransmitter. Alertness, inflammation, gastric secretion
what does tyramine do
Not a neurotransmitter and cannot pass the BB barrier. Vasoconstrictor, found in food– especially fermented foods. MAO in the gut break it down—unless a drug inhibits MAO
what category does fluoxetine (prozac) fall into
SSRI
what is a syndrome caused by prosac
serotonin syndrome
what is serotonin syndrome
Rare and life-threatening event
Risk greatest when SSRI is administered in combination with monoamine oxidase inhibitor (MAOI), some cold medicines
how does SSRIs work
By blocking neuronal uptake there is more serotonin left at the synapse
why do SSRIs take up to 6 weeks to have full effect
The way SSRI block reuptake is by affecting the creation of transporter molecules which carry the serotonin back to the neuron. At first, there are plenty of old transporter molecules to do the job. It takes time to clear these out.
what happens if you suddenly stop SSRIs
Withdrawal sx: dizziness, tremors, GI
what are the rare life threatening symotomss of serotonin syndrome
Abdominal pain, diarrhea, bloating Restlessness, fever, high b/P Mood swings, Delirium, seizures Tonic rigidity Apnea, death
how do you stop increased risks of taking SSRIs and MAOI
Need to wait 5 weeks after stopping SSRI before switching to MAOI, and 2 wks if going to SSRI from MAOI
what are the emergency measures to stop serotonin syndrome
- Discontinue SSRI
2. Symptomatic TX

A. Drugs to block serotonin receptors B. Cooling blankets. C. Dantrolene or diazepam for rigidity D. anticonvulsants E. artificial respiration

Increased levels (tyramine) lead to HTN, hypertensive crisis, CVA, and possible death
what does transcutaneous delivery of an MAOI with a patch called the selegiline transdermal system (STS). help in
At doses up to 6mg over 24 h—no tyramine restriction in diet. Higher doses still require diet.

what is an SARI
Nefazodone (Serzone) or Buspirone (Buspar)
what is an SSNRI
Venlafaxine (Effexor) and others inhibit reuptake of serotonin and norepinephrine
what does an Electroconvulsive therapy (ECT) do
Procedure (like surgery) consents, anesthesia, muscle paralytics.
what are the potential adverse reactions of Electroconvulsive Therapy (ECT)
Confusion, Memory lapses
when would Electroconvulsive Therapy (ECT) be indicated
Patient is suicidal or homicidal.
Agitation or stupor is extreme.
Life-threatening illness is a result of the refusal of foods or fluids.
History includes a poor drug response or a good ECT response.
Standard medical treatment has no effect.
Bipolar spectrum disorders arecharacterized by two opposite poles:
mania and depression
what are the Psychological Co-morbidity of bi polar
Anxiety disorders

Behavioral disorders
Substance and anxiety disorders worsen the prognosis and greatly increase the risk of suicide
what are the medical co-morbidity of bi polar
Cardiovascular
Cerebrovascular
Metabolic disorders
Conditions associated with manic symptoms (e.g., central nervous system [CNS] tumors or trauma, hypothyroidism, seizure disorders, human immunodeficiency virus [HIV])
what are the biological theories of bi polar
Genetics
Neurobiological
Neuroendocrine
Neuroanatomical
what are the psychological influences and cultural considerations of bi polar
- Stressful life events can trigger bipolar spectrum disorders(BSDs).
- Child abuse a factor in severity
- Cultural differences and beliefs can
- vastly complicate the issue.
- Hearing voices may be seen as divine
what are some hypomania symptoms
- Talks, jokes, may be crude or sexual
- Pressured speech
- Mood persistently elevated, euphoric inappropriate
- Grandiose, judgement is poor
- Deceased attention span
- Overactive
- Hypersexual, voracious appetite, decreased need for sleep, financially extravagant
what are some symptoms of acute mania
- Labile Mood, good humor to rage
- Intrusive, demanding of attention
- Profane, sexually crude remarks
- Flight of Ideas and clang -association (Manic Mechanic)
- Grandiosity that is out of contact with reality, extremely poor judgement
