What are the symptoms of schizophrenia?
Symptoms of schizophrenia can be divided into categories of postive and negative symptoms.
Schizophrenia symptoms usually develop slowly over months or years. Sometimes you may have many symptoms, and at other times you may only have a few symptoms
At first, you may have the following symptoms:
•Irritable or tense feeling
As the illness continues, you may have problems with thinking, emotions, and behavior, including:
•Hearing or seeing things that are not there (hallucinations)
•Lack of emotion (flat affect)
•Problems paying attention
•Strongly held beliefs that are not real (delusions)
•Thoughts that "jump" between different topics (“loose associations”)
Symptoms depend on the type of schizophrenia you have.
Paranoid schizophrenia symptoms may include:
•Anger or arguing
•False beliefs that others are trying to harm you or your loved ones
Disorganized schizophrenia symptoms may include:
•Problems thinking and explaining your ideas clearly
•Showing little emotion
Catatonic schizophrenia symptoms may include:
•Grimacing or other odd expressions on the face
•Lack of activity
•Not responding much to other people
•Rigid muscles and posture
In schizophrenia , the concordance rate is about
50 percent in identical twins and about 17 percent in fraternal twins. Abnormal eye movements might represent deficits in executive cognitive functions, normally carried out by the frontal lobes, and in goal-related behaviors in particular.
Rates of schizophrenia are somewhat higher in urban environments.
may arise from poverty, poor nutrition, and the stress related to racism.
It is five times more likely in lower than in the middle or higher socioeconomic groups.
Treatments for schizophrenia &
Typical anti psychotics primary benefit patients with schizophrenia by reducing positive symptoms. Negative symptoms, such as social withdrawal and emotional disturbances, do not appear to respond much to these medications.
Tardive dyskinesia is a common and troubling side effect of these drugs. ( tardive refers to 'slow' and dyskinesia means 'difficulty moving' )
Advantages of these newer medications is a reduction in negative symptoms as well as in positive symptoms, in some patients.
Weight gain and diabetes in many patients and still carry the risk of producing tardive dyskinesia.
What is a Mood Disorder?
Mood disorder is the term designating a group of diagnoses in the DSM-IV classification system where a disturbance in the person's mood is hypothesized to be the main underlying feature
Major Depressive disorder (MDD)
DSM-IV defines major depressive episodes as periods pf pervasive sadness that last for at least 2 weeks.
Genetics of depression
Genes play a major role in MDD
33 percent of depression in twins appear.
A number of genes have been implicated in depression, including those involved with serotonin reuptake and the clock genes.
In the absence os stressful life events, having a short copy is not sufficient to cause depression.
Prenatal events might contribute to a vulnerability to mood disorder. Stress often serves as a trigger for depressive episodes.
Treatments for major depression
Treatment for major depressive disorders takes a number of pathways. Prescription of some type of antidepressant medication, partculary an SSRI.
The ability to stimulate neurogenesis in the hippocampus.
Animal studies, drugs that block neurogenesis also prevent the therapeutic effects of antidepressants (ibid).
30-35 % with MDD treated SSRIs meet criteria.
* Cognitive behavioral therapy typically produces the best long-term outcomes for patients with depression.
What is Bipolar Disorder?
Bipolar disoder is characterized be alternating cycles of depression and mania. Mania consists of " a distinct period of abnormally and persistently elevated, expansive.
Genes appear to play a more significant role in bipolar disoder than in major depressive disorder.
Adoption studies also support a powerful role of genetic in the development of bipolar disoder.
Bipolar disorder is 3 to 4 times more common.
As for many of the environmental factors Diet is a great cause.
Dietary omega-3 fatty acids, generally found in fish might provide some protection from bipolar disorder.

•Little need for sleep
•Poor temper control
•Reckless behavior and lack of self control
•Binge eating, drinking, and/or drug use

ECT therapy relaxant while seizures are induced by electricity.
Any duration if hospitalization is necessary.
What is Anxiety Disorder?
Anxiety disorder take many forms, but all share the core element of anxiety, a strong negative emotion arising from the anticipation of danger.
Treatment for anxiety disorders typically combines medication with cognitive- behavioral therapy to help the person learn to manage reactions to anxiety producing stimuli.

Typical obsessions include thoughts of germs and disease, fear for safety of the self or others, symmetry, and religious or moral concerns.
counting & arranging
OCD is treated using medications and therapy.
The first medication usually considered is a type of antidepressant called a selective serotonin reuptake inhibitor (SSRI).
