The involvement of monoaminergic neurons in Dementia of Alzheimer Type (D.A.T.) is still a matter for debate. In a selected group of patients with D.A.T. we evaluated monoamine levels in cerebrospinal fluid (CSF) and plasma and found a significant decrease in serotonin and dopamine metebolite levels. Dopamine levels were reduced in both CSF and plasma. Moreover, a significant correlation was found between the duration of the illness and the decrease in monoamine levels. These findings suggest that there is systemic damage to monoaminergic neurons in D.A.T.

Abstract
The involvement of monoaminergic neurons in Dementia of Alzheimer Type (D.A.T.) is still a matter for debate. In a selected group of patients with D.A.T. we evaluated monoamine levels in cerebrospinal fluid (CSF) and plasma and found a significant decrease in serotonin and dopamine metebolite levels. Dopamine levels were reduced in both CSF and plasma. Moreover, a significant correlation was found between the duration of the illness and the decrease in monoamine levels. These findings suggest that there is systemic damage to monoaminergic neurons in D.A.T.
