Transcript of Biology TechYes Project

By: Delia Sandoval How does Schizophrenia affect the mind? Is there a cure? Standard 9b: Video: Schizophrenia is a group of psychotic disorders that make it hard to tell what is real and not real, think clearly, have normal emotional responses, and act normally in social situations. Schizophrenia means "split mind", it's like having two different personalities. Standard 9e: - Students know the roles of sensory neurons, inter neurons, and motor neurons in sensation, thought, and response Negative Symptoms A lack of behaviors or feelings that usually are present, such as: Positive Symptoms Extra feelings or behaviors that are usually not present, such as: - Actually there is no cure for Schizophrenia. However, the symptoms can be treated with medication and therapy. - Students know how the nervous system mediates communication between different parts of the body and the body's interactions with the environment. About Schizophrenia Schizophrenia symptoms are generally separated into 2 categories (positive & negative). Believing that what other people are saying is not true (delusions).
Hearing, seeing, tasting, feeling, or smelling things that others do not experience (hallucinations).
Disorganized speech and behavior.
Being paranoid. Losing interest in everyday activities, like bathing, grooming, or getting dressed
Feeling out of touch with others
Lack of feeling or emotion
Having little emotion or inappropriate feelings in certain situations
Having less ability to experience pleasure More Information: People with Schizophrenia may hear voices in their head that others do not hear. They also may think that others are reading their minds, controlling what they are thinking, and/or planning some sort of harm towards them. The cause of Schizophrenia is unknown. There is no single cause for Schizophrenia. It seems to be the outcome of multiple causes: genetic factors, environmental and psychological assaults. ~ Mediates: goes between ~Sensory Neurons: a neuron that conducts impulses to the brain or spinal cord. The Nervous System: The nervous system is the body's central control system. It basically controls how the whole body functions, how it reacts to certain temperatures, the movements it does, and the how it sensors everything. The nervous system helps function the body by sending electrochemical impulses through nerves to muscles and glands. *Most doctors think the most common cause for Schizophrenia is drugs. ~ The positive symptoms have to do with matters of thinking and behavior, negative symptoms have to do with lack of doing activities. - Neuroleptics are psychiatric medications that are used to treat symptoms of certain types of mental illnesses, for example: Schizophrenia. Catatonic Schizophrenia: Catatonic Schizophrenia is a type of schizophrenia that has extremes of behaviors. There is a dramatic reduction in activities where almost all movements stop, the person may not be able to speak, move, or respond. (Could be known as a catatonic stupor).
Other extremes of behaviors are being over excited or hyperactive, mocking sounds or movements around them.
Catatonic Schizophrenia is rarer than usual because the treatments there is for it have improved. Schizophrenia affects the brain, there are abnormalities with the brain's structure due to Schizophrenia. These abnormalities can cause nerve damage in the nervous system, also can cause problems with the pathways that carry brain chemicals. Neurons: Neurotransmitters are the "messengers" of the brain, they carry information from brain cell to the other.
Dopamine is a neurotransmitter that is involved with the movements and thoughts. Also with feelings of pleasure and well-being, Schizophrenia affects dopamine by having lack of being able to experience pleasure. Dopamine pathways in the brain could influence different kinds of behavior or thinking, high dopamine in parts of the brain can cause paranoid thinking, which is a symptom of Schizophrenia.
Glutamate is another type of neurotransmitter, it has to do with the formation of memory. Dopamine also reduces the act of glutamate. Some hallucinogenic drugs block glutamate receptors; they can also cause paranoia that imitates the schizophrenic symptoms.

N.d. Photograph. N.p. Why I Chose This Topic I chose to do my project on Schizophrenia because I found this mental illness interesting.
Also because I know a couple of people who suffer from this illness and I wanted to do further research on it and let others know about it since it is not very known.
