There are different subtypes of depressive syndromes in geriatrics with particular characteristics not considered in the diagnostic criteria of DSM IV and ICD 10. Objective: To study the depressive syndromes present in the geriatric population. Materials and Methods: 109 elderly depressed patients were evaluated and 30 normal controls matched for age and schooling with a neuropsychiatric interview, an extensive neuropsychological battery and neuroimaging study. Depressed patients were classified into 4 groups using the SCAN 2005 (WHO): major depression (n = 34), dysthymia (n: 29), Depression Subsindromática (n: 28), depression associated with medical illness (dementia) (n: . 18) Results: marital status (OR: 3.4, CI: 1.2-9.6), work (OR 5.3, CI: Among depressive patients and controls significant differences (p <.05) in the risk factors found 2-14), cardiac history (OR: 12.5 CI: 1.6-96.3) and dyslipidemia. Significant differences on neuroimaging in the neuropsychological tests, activities of daily living and caregiver burden were also demonstrated. Among the different groups of depressive there were significant differences in neuropsychological assessment and neuroimaging. Conclusion: There are different subtypes of depression in geriatrics with clinical features that distinguish depression in young adults. Among other causes, depression in the elderly may be the initial symptom of a dementing process or the expression of cerebrovascular disease.
