Sychiatry is Pseudo Pscience. HARM is the middle word in PsychopHARMacology. These are torture drugs of permanent harm. There are no therapeutic effects or any side effects; only toxicity spectra. Psychiatry is a criminal enterprise that has deceived and silenced government by it's craft. Psychiatry is not science. Psychiatry is not medicine. Psychiatry is an activity of fortune seeking soldiers and greedy witches. One who first sets mind or hand to the practice of Psychiatry has abandoned the value of "Do No Harm".

Sir, I thought Atypical Antipsychotics blocks D4 receptor and 5-hydroxytryptamine. So what's the difference between D2 and D4 receptor?
Kayla Añasco (28 дней назад)
+Speed Pharmacology Thank you sir. Now I understand the difference between the two.

"The higher affinity of clozapine for D4 than for D2 receptors led to the speculation that the superior clinical profile of this drug was due to D4 receptor blockade (Van Tol et al. 1991). However, several typical antipsychotic drugs, including haloperidol, have similar affinity for D2 and D4 receptors (Roth et al. 1995), whereas several atypical drugs, including quetiapine and amisulpride, have very low D4 affinity, suggesting that D4 affinity per se does not confer therapeutic efficacy or low EPS liability. Moreover, several clinical trials with D4 selective antagonists failed to show antipsychotic efficacy (Bristow et al. 1997; Corrigan et al. 2004; Kramer et al. 1997)" Source: "Current Antipsychotics" by Gerhard Gross & Mark A. Geyer eds., 2012 page 35-36.

Is there more dopamine in the mesocortical pathway which is why there is less negative symptoms when taking Atypical antipsychotics? And theres less risk of Extra Pyramidial Side Effects because of more Dopamine in the striatial pathway? Can someone clarify my brains fried.
Half Tomato (1 месяц назад)
Atypicals block seratonin receptors causing Dopamine to increase. And this Dopamine attaches to D2 receptor but removed quickly. Attaches and go! And this might give the similar function of normal level of dopamine. Dopamine is more but action is less!
Malek Bitar (1 месяц назад)
Blockade of serotonin receptors will increase dopamine levels in desirable area. Thus, less Extra Pyramidial side effects.

Is there more dopamine in the mesocortical pathway which is why there is less negative symptoms when taking Atypical antipsychotics? I guess there is something to do with antagonist effects on 5HT2A receptor. There is less risk of Extra Pyramidal Side Effects because of more Dopamine in the striatial pathway? Atypical antipsychotics has less suppression effects on migrostriatal pathway due to less affinity on dopamine receptor. (That's my understanding, not 100% sure it's accurate)

Nice video. I like the fact that you went into specific dopamine receptor selectivity and the different dopaminergic pathways that can be implicated. Subscribed to your channel. :)

How doe you differentiate between positive and negative phychotic symptoms that you speak of?
Mental Health with Dr Elliott (2 месяца назад)
Negative symptoms are incredibly hard to treat and can often appear similar to extra-pyrimidal side effects from first generation antipsychotics (usually in people taking these via depots) or from sedation on olanzapine or clozapine. Amisulpride is a 2nd generation with (I believe) some loose evidence for improving negative symptoms but it's still a tricky one.
Speed Pharmacology (3 месяца назад)
Positive symptoms refer to an excess or distortion of normal functions (hallucinations and delusions). Negative symptoms refer to a decrease or absence of normal behavior (lack of motivation, restrictions in emotional and verbal expressiveness, social disengagement)
