1. Brain - disorders

According to current medical thinking, actual physical problems in the brain may cause many behavioural disorders in humans. Problems with depression, insomnia and other disorders have been linked to the presence or absence of certain chemical neurotransmitters in the brain. However, it is not clearly understood if the unusual levels of transmitters is the cause of disorder or just a side effect of the disorder itself.

Review the following effects of neurotransmitters focusing on the problems associated with each type.
