1. The role of dopamine in psychotic alterations.
· Role
The role of dopamine can best be explained or described as the neurochemical switch that is capable of converting the neural representation of the neural response into a motivationally important experience. Research shows that their idea into the psychiatric areas by elongating the role or function of the dopamine from the motivational indication to the mediator. Due to this idea or perception, the formation of psychotic sign is associated with the disordered and stimulus-independent production of the dopamine from the
ain. The immediate firing of the dopaminergic neurons to trivial on a daily basis results in a raised attention as well as attribution of an excessive motivational effect to this stimuli. This evident clarifies why a random daily activities, for example; an account of a television anchorperson on the earth’s surface layer, is capable of being assigned with inadequate significance, for instance, the person is credited to the own individual in the situation of illusions of the reference, and may at the same time gain motivational control to drive a raised strange behaviors, for example, hiding off the apartment walls using the metal panels (Heike, 2013).
· How the role of first-generation and second-generation antipsychotics diffe
First generation ‘typical’ antipsychotic is a sequence of class of the antipsychotic as compared to the second generation antipsychotics (Ruben, 2016). First generation antipsychotics are applied or used majorly in treating the positive symptoms, for example; hallucinations as well as delusions. The Second generation antipsychotics are as well helpful for the positive signs but for the schizophrenia and at the same time it is claimed that they are more effect as compared to the First generation antipsychotics in treating the negative symptoms of the schizophrenia (Pmhdev, n.d.). Furthermore, the negative signs of symptoms comprises of the emotional expressions, social contacts, mindset or a state of thinking and motivation. High potency first generation antipsychotics always have a high affinity for the dopamine receptor and hence, they induce extra-pyramidal risks or side effects through the blockage of the dopamine receptors. Extra-pyramidal risks or side effects comprises of the dysknessias: (repetitive, involuntary as well as facial movements or meaningless body movements), Parkinsonism;...
