Anxiety Disorder: There are five major classes of anxiety disorders: generalized anxiety disorders, phobic anxiety disorders, panic disorders, obsessive-compulsive disorders, and post traumatic stress disorder (PTSD).

Outline and evaluate one or more biological explanations for schizophrenia The biochemical explanation is one explanation for the cause of schizophrenia in terms of the release of neurotransmitters. This suggests that schizophrenia could be caused by an excess amount of dopamine in the brain. This is due to receptor cells requiring dopamine to fire so with a large amount of dopamine present it is activated too much and too many messages are sent. This is what could account for the confused and the erratic behaviour which is seen in schizophrenic patients. Support for this theory is the effect of amphetamines.
Schizophrenia & Other Psychotic Disorders: Schizophrenia, Delusional Disorder, brief Psychosis, Schizo-affective Disorder & Shared Psychotic Disorder. SchizophreniaSchizophrenia is a psychotic illness which can affect people in variety of ways, there is no evidence as yet why one develops the illness. Studies suggest there can be a combination of factors which can trigger the illness. It is agreed by health professionals that schizophrenia is most likely caused by a combination of factors, which can include the following: Dopamine is one of the chemicals that carry messages between brain cells and if there is too much Dopamine it can be a factor of one developing the illness. Genetic can play a big part in someone developing the illness as they are more vulnerable to the illness.
Common side effects from antipsychotics may include: •Sleepiness (sedation) •Dizziness •Weight gain •Increased chance of diabetes and high cholesterol •Feelings of restlessness or "jitters" •Slowed movements •Tremor Long-term use of antipsychotic medications may increase your risk for a movement disorder called tardive dyskinesia. This condition causes repeated movements that you cannot control, especially around the mouth. Call your doctor right away if you think you may have this
Enhancing an inhibitor has the effect of making a person sluggish. Also, alcohol weakens the excitatory neurotransmitter glutamine, which enhances the sluggishness even farther. The Central Nervous System: The central nervous system (CNS) includes the brain, the spinal cord, and the nerves originating from it. Sensory impulses are transmitted to the CNS and motor impulses pass from it. When alcohol acts on the CNS, intoxication occurs, affecting emotional and sensory function, judgment, memory and learning ability.
Heroin Addiction Treatment Options 1 Can Heroin Addiction be treated? Alternative Treatment Modalities for Heroin Dependence. Maritza Padilla Psychology – 230-1241 Professor B. Harrington November 3, 2012 Heroin Addiction Treatment Options 2 Heroin is a powerful narcotic derived from morphine, which is obtained from the opium poppy. Heroin impacts the brain and acts as a painkiller. It affects the brain's pleasure systems and interferes with the brain's ability to perceive pain by depressing nerve transmission in the sensory pathways of the spinal cord and brain that signal pain.
Many researchers, such as Crow (1985) believe there are two different types of SZ with different underlying pathology. Type 1 SZ is the type of SZ which would be associated with the Dopamine Hypothesis; it involves DA dysfunction, is characterised by positive symptoms and responds well to anti-psychotic medication. Type 2 SZ, however, is the type that is unsupportive of the Dopamine Hypothesis- it is a neurodevelopmental disorder arising from prenatal insults or perinatal insults, characterised by negative symptoms and does not respond well to antipsychotic drugs. The idea of different types of SZ suggests that DA is not the only
There are three main types of Schizophrenias. The first type is Paranoid Schizophrenic; people with this suffer preoccupation with persecutory and/or grandiose delusions. The second type is Disorganized Schizophrenic; they suffer from speech and behavior problems and they have a flat of inappropriate affect. The third type is Catatonic Schizophrenic; in this case the person gets motor immobility or excessive motor activity that is purposeless, peculiar movements, echolalia, orechopraxia. In America there are about 2.2 million people with this illness.
With things like diabetes, cancer and so on, the illness can be diagnosed by scans or blood tests. Schizophrenia and other mental illnesses have to be diagnosed and classified purely based on symptoms the patient is experiencing. Schizophrenia is particularly difficult to diagnose because it has many symptoms, some of which are similar to other mental illnesses such as bipolar disorder. This brings up the issue of differential diagnosis. Even some physical illnesses can cause symptoms that appear to be those of schizophrenia, for example temporal lobe epilepsy can have symptoms that can be mistaken for schizophrenia, and this can lead to misdiagnosis and a patient could end up being treated for the wrong illness completely.
Schizophrenia is a complex disorder in which there is a distortion of reality. There are many different explanations for schizophrenia and therefore a number of different treatments based on these explanations which aim to address these different explanations. Some psychologists believe that schizophrenia is due to abnormal neurochemistry and proposed the dopamine hypothesis. This biological approach suggests that schizophrenia can be treated using drug treatments. Chlorpromazine is a type of phenothiazine which is a neuroleptic.
