The suspected cause of schizophrenia is an abnormal increase in the neurotransmitter dopamine in the brain. This dysregulation is thought to contribute to the positive symptoms of schizophrenia, such as hallucinations and delusions. Researchers believe that an overactivity of dopamine pathways, particularly in regions like the mesolimbic system, plays a significant role in the development of the disorder.
The action of the excitatory neurotransmitter will increase, since its concentration in the synapse will rise.
Beta 1 receptors
Dopamine is the neurotransmitter that drugs increase, leading to pleasurable feelings. It plays a key role in the brain's reward system and is associated with motivation, reinforcement, and pleasure.
-cytosis indicates an abnormal increase in a type of cell, and -penia indicates an abnormal decrease. So leukocytosis is abnormal increase in white blood cells, and leukopenia is an abnormal deficiency of white blood cells.

Leukemia is an increase in the number of abnormal white blood cells in the bloodstream. These abnormal cells do not function properly and can crowd out normal white blood cells, leading to a weakened immune system.
Infection is one possible reason for an abnormal increase in the number of WBC's (white blood cells).
