Provide a 5 pages analysis while answering the following question: Psychiatric Disorders. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required.
A very complex relationship of causation factors and the manifestation of the various psychiatric disorders make it difficult to diagnose and treat them, with a huge gap still existing on their development mechanisms. In this discourse, several psychiatric disorders are discussed with a presentation of views on theory and effective drug regimes, also accompanying the presentation. .  . .
Schizophrenia(s) involves a spectrum of disorders characterized by disjointed psychic functioning earlier though to be constituted by the breakdown in the coordination of emotions, thinking and actions among the victims.
Usually, extreme mental illnesses such as madness are linked with schizophrenia. A major observation in the spectrum of disorders referred to as schizophrenia is a changing manifestation pattern as the victim progresses in age. The difficulty in devising appropriate interventions in this category of disorders is spelled by several overlapping symptoms that may also be experienced by victims of neurological disorders. Some of the key diagnosis symptoms for schizophrenia include. delusional thoughts, inappropriate effects, hallucinations, incoherent thinking, and odd behavior.
Repetitive occurrence and the manifestation of any two of these symptoms is sufficient to suspect schizophrenia (Pinel, 2009).
Major theoretical explanations for the establishment of schizophrenia are developmental and dopamine theories. Developmental theories attach meaning to faulty brain development possibilities at the fetal or infant stages that subsequently affect psychological development. Dopamine theory relies on the premise that a high concentration of dopamine leads to schizophrenia.
Drugs of choice over the research period have included chlorpromazine and other phenothiazines (inactivation of dopamine receptors D1 and D2 and its activity but reduces severity in some schizophrenias but activates others), reserpine (abandoned because effective dosage generates severe drops in blood pressure). Haloperidol, droperidol and other butyrophenones act similarly as chlorpromazine but only on D2 receptors and have a higher receptor binding effectiveness than chlorpromazine. Both drugs cause Parkinson’s related symptoms.
