    I passed board today. I only used these CZcams videos and the purple book and I believe these are all you need. There is another channel on CZcams the one with the light 💡that I used. I didn't buy any questions or review. Purple book I got from a friend. Thank you so much for these videos they really helped me pass. Good luck.

      @@only1mesabby the purple book is the ANCC guide to passing boards for PMHNP. The purple book and this book, along with the Fitzgerald course provided by my school is all I am using. Just those three items alone are enough to keep me busy.

    NOTES:
    3 RULES of Neurotransmission:
    1. What goes up, must come down: Intoxication and Withdrawal
    2. A neurotransmitter is not easily fooled: Up regulation (decrease amt. of neurotransmitter, synapse will make itself more sensitive) and Down regulation (increase the amount of neurotransmitter, synapse removes receptors, making it less sensitive to the drug), observed during drug tolerance and withdrawal, regulation of G protein and DNA
    3. With great power comes great responsibility: More efficacy and More Severe side effects
    • full agonist mimics the effect of a neurotransmitter
    • a partial agonist mimics it but only to a certain lower point
    • an antagonist blocks the effect of a neurotransmitter
    • inverse agonist produces an opposite effect to the neurotransmitter
    Dopamine: Reward pathway located in VENTRAL TEGMENTAL AREA, Nucleus Accumbens is imp area
    - D: Drive (governs motivation and reward)
    - O: Psychosis (blockade mitigates some features like delusions and hallucinations)
    - P: Parkinsonism (decreased secretion linked to Parkinson's pathology)
    - A: Attention (boosting dopamine improves attention and concentration)
    - M: Motor (strongly linked to motor function, imbalances cause conditions like Parkinson's)
    - I: Inhibition of prolactin (crucial in regulating prolactin release) (prior name: Prolactin inhibiting factor)
    When dopamine is blocked, one side effect is milk release from the breasts.
    - N: Narcotics (release of dopamine plays a role in addiction)
    - E: Extrapyramidal (controls motor functions, blocking leads to significant motor side-effects)
    Serotonin: complex molecule with many roles, comes from the RAPHE NUCLEI
    Also known as 5-HT (5-hydroxytryptamine)
    - Head: Depression, anxiety, social interaction (sociality), impulsivity, sex drive, migraines, satisfaction
    - Red: Platelet binding and adhesion, interfering with its function cause bleeding
    - Fed: GI tract motility (90% of all serotonin in GI tract), nausea (serotonin blocking medications effective)
    Serotonin Syndrome: 2 serotonergic drugs are taken at the same time
    Head: Headache, Agitation, Confusion
    Red: Flushed, warm skin (Hyperthermia, Hypertonia, Sweating, Tachycardia)
    Dead: Mortality 2 to 12%
    Norepinephrine: LOCUS COERULEUS origin, regulates Sympathetic nervous system
    - Fight-or-flight response
    - when active, Norepinephrine lots into the brain and epinephrine peripherally into the bloodstream
    - Sympathetic Innervation
    Central (Concentration, attention, vigilance, energy)
    Peripheral (Tachycardia, Hypertension, Glucose, Essential organs)
    Brain off and on switches: Gaba (off), Glutamate (on)
    GABA (Gamma-Aminobutyric Acid):
    - Inhibitory neurotransmitter
    - "Gaba" association with a boring lecturer inducing sleepiness
    - Relaxation (breathing and muscles), euphoria, no anxiety
    - Drugs that enhance GABA are often used to break a seizure.
    Glutamate:
    - Excitatory neurotransmitter
    - Association with mating for recall
    Histamine: The upper brain cortex depends upon a constant stream of histamine for activation, once supply is cut off, cortex shuts down
    - H for hay fever
    - I for itching
    - S for sleeping
    Antihistamine: Itching and hay fever disappears, patient gets sleep
    First generation anti-histamines: (diphenhydramine or benadryl) used for sedation as they work in both central and peripheral NS
    Newer antihistamines: (loratadine or claritin) works peripherally therefore advertised as non-drowsy
    Acetylcholine (ACh): opp of Norepinephrine, responsible for regulating Parasympathetic system
    - A: Autonomic functions (rest and digest functions: Bradycardia, GI motility, Salivation, Lacrimation, Urination and Sexual Arousal)
    - C: Contraction (neuromuscular junction) drugs that affect ACH peripherally are used against
    neuromuscular diseases like myasthenia gravis
    - H: Hippocampus (memory, learning, awakeness and attention), helps combat Alzheimer’s dementia, geriatric psychiatry
    Opioids:
    - Armed Chinese man association with the Opium Wars

    • A: Analgesia (pain relief)
    • R: Respiratory depression (opioids make the respiratory center in the brain insensitive carbon dioxide so death and opioid overdoses via Ondine's curse)
    • M: Meiosis/ Constriction of pupils (pinpoint pupils)
    • E: Euphoria
    • D: Drowsiness
    • C: Constipation

    Important historical point: the Opium Wars were not fought because people wanted more access to opium, as you suggest. The Chinese tried to ban British opium sales in China to protect their citizens from addiction. The British, not wanting to lose their massive profits, started a war and forced the Chinese government to set up protected trade ports allowing them to continue shipping opium into China. Otherwise, great mnemonics and info, thank you!

    Neurotransmitter: A neurochemical emitted between the junction or synapse between neurons causing bio-electrical impulses to travel between neurons and increase synaptic efficiency (connectivity), and as an emergent property, comprises thinking. For cognitive and evolutionary psychologists, the bio is removed from the electrical, and the electrical metaphor is used, making the brain into a computer, neurons into circuitry, and neurotransmitters into the stuff that powers a light bulb, which metaphorically came on for the dim bulb psychologists who came up with the idea.

      *SCHIZOPHRENIA TREATMENT BREAKTHROUGH: My heart goes out to everyone who have or cares for a mentally ill person, there should be no shame. I once believed Schizophrenia or mental illness has no cure... Well, it is true with antipsychotic medicine, but not with Consummo Herbal Medicine. To be clear, there is no pharmaceutical medicine, no magic pill that has any significant effect on the progressive downhill course of this disease. My daughter's experience opened my eyes to the reality of a cure through the wonders of herbs. My daughter was diagnosed with schizophrenia many years ago... I spent more time in hospital than out of hospital. She had a major breakthrough only with CONSUMMO treatment. She has been well and living her best life. While there may be other different options to look into, never make your own success path a secret. I consider myself an advocate for people who don’t have a voice. I don't want people to feel that suicide is their only option.

  • @MsMadamadamada
    @MsMadamadamada Před 2 lety +1

    You say everytime you give a drug to increase a neurotransmitter receptors for that neurotransmitter will downregulate..? I'm confused because SSRIs work by increasing serotonin in the synapse because there's lack of it. So per your sentence our body would downregulate receptors for serotonin... but that's bad because when we take away the drug we will be left with less receptors--> less serotonin binding--> unsolved issue. What am I missing?

    • @MemorablePsych
      @MemorablePsych  Před 2 lety

      While the brain does down regulate serotonin receptors in response to increased serotonin in the synapse, there is a limit to how much it can do this! Eventually the brain won't down regulate any further, but the extra serotonin will still be there. It is thought that this, at least in part, may explain the delayed effect of antidepressants!

    Is there a reason why ADHD patients are put on stimulants instead of depressants? like why should the intoxication be high?

    • @Seebzters
      @Seebzters Před 4 lety

      A stimulant is methamphetamine and a depressant is benzodiazepine. So, essentially an agonist when bound to a receptor produces a certain effect and an antagonist blocks the natural effect of the receptor. So far, dopamine is for drive and reward, blocking delusions and hallucinations, increases concentration, used for motor function (and thus why Parkison's disease patients can't walk as well), and it also blocks the release of milk from breasts
