American psychiatric association and has been revised several times since it was first published in 1952. Numerous kinds of brain problems are linked to abnormal functioning. For example, huntington"s disease, a disorder marked by violent emotional outbursts, memory loss, suicidal thinking, involuntary body movements, and absurd beliefs, has been linked to the loss of cells in the striatum (part of the basal ganglia). Neuroscientists have linked some mental disorders to deficient or excessive activity of different neurotransmitters in the brain. Depression, for example, seems to be related to insufficient activity of the neurotransmitters norepinephrine and serotonin (beck & alford, 2009). Another possible source of abnormal brain structure or biochemical abnormal functioning appears to be viral infections.
