1cite The Readings And Multimedia In The Module To Support Your Comme

Cite the readings and multimedia in the module to support your comments. In your own words, describe what would happen in your brain from a neurobiological perspective if you were experiencing psychosis. How might you convey to a client what is happening in their brain when they experience psychosis? Highlight and summarize at least two insights you have from the Preston and Bentley texts, readings, and videos in the module.

Paper For Above instruction

Understanding psychosis from a neurobiological perspective involves examining the complex interactions within the brain that give rise to the symptoms experienced during a psychotic episode. According to Preston (2011), psychosis is associated with dysregulation in dopamine pathways, particularly an overactivity of dopamine in the mesolimbic pathway. This overactivity results in the brain interpreting normal stimuli as threatening or false, leading to hallucinations and delusions. Bentley (2012) further explains that neuroanatomical alterations, such as enlarged ventricles and reduced gray matter in certain brain areas like the prefrontal cortex, contribute significantly to the cognitive disruptions observed in psychosis.

From a neurobiological standpoint, if I were experiencing psychosis, my brain would likely be experiencing an abnormal release or heightened sensitivity to dopamine neurotransmitters. This imbalance would affect various neural circuits, particularly those involved in perception, thought processes, and emotional regulation. As a result, I might perceive vivid hallucinations—seeing or hearing things that are not present—due to hyperactive sensory processing. Simultaneously, the brain’s interpretation of reality would be distorted, leading to paranoid delusions or disorganized thinking. These symptoms arise because the brain’s usual filters and interpretative mechanisms are compromised, making it difficult to distinguish reality from hallucination or delusion (Preston, 2011; Bentley, 2012).

When conveying this to a client, I would emphasize that psychosis involves real changes in brain chemistry and structure. I would explain that their brain is experiencing a temporary imbalance in neurotransmitters, which causes the perception of things that aren’t really there. It is akin to a malfunction in the brain’s software, leading to distorted perceptions and beliefs. Assuring the client that these experiences are rooted in biological processes can help normalize their symptoms and remove stigma, fostering trust and encouraging treatment adherence.

Two key insights from the Preston and Bentley texts are the importance of understanding the neurochemical basis of psychosis and the impact of structural brain changes on cognitive function. Preston (2011) emphasizes that antipsychotic medications primarily target dopamine dysregulation, which alleviates hallucinations and delusions. Bentley (2012) highlights that neuroimaging studies reveal consistent structural abnormalities in individuals with psychosis, underscoring the biological underpinnings of the disorder. The videos further illustrated how neurobiological models bridge the gap between underlying brain mechanisms and clinical symptoms, providing a comprehensive understanding of psychosis that informs treatment strategies.
