What is Schizophrenia?

Schizophrenia is a chronic, severe, and disabling brain disorder that affects about 1 percent of people all over the world. People with schizophrenia sometimes hear voices others don’t hear, believe that others are broadcasting their thoughts to the world, or become convinced that others are plotting to harm them.  The illness usually starts in the teenage years or twenties and alters the person’s experience and interpretation of the world. This may lead to delusions – strongly held false beliefs. scientists think that a malfunction of neurons in the brain areas that deal with emotions, memory, and planning may be to blame. Scientists hope that identifying genes that predispose people to schizophrenia will help find treatments. Traditional antipsychotic drug treatments for schizophrenia block receptors for the neurotransmitter dopamine in the brain. They are effective in relieving hallucinations and delusions but have little effect on other symptoms: lack of motivation, tiredness, and depression.
