Schizophrenia
The
brain is one of the most vital organs of the
central nervous system along with the spinal cord.
It controls physical body functions like the heart
rate and respiration, and also controls our
emotions, thoughts, etc.
The
brain is a collection of 10 billion interconnected
neurons in which messages are passed from one
neuron to another through neurotransmitters like
dopamine and serotonin.
Schizophrenia is a syndrome characterized by
disturbances in emotions, thought, activity, and
language, that leaves patients fearful and
withdrawn.
The
cause of schizophrenia is not entirely clear. It
may occur due to an increase in the level of
dopamine in the mesolimbic pathway which leads to
positive symptoms such as delusions,
hallucinations and conceptual disorganization.
Schizophrenia may also occur due to a decrease in
the level of dopamine in the prefrontal cortex
which leads to negative symptoms such as loss of
function, lack of interest, impaired
concentration, lack of energy and lack of
motivation.
