Aging is a natural and inevitable process leading organizations live to change over time after the phase of maturity. His progress is highly variable from one individual to another. So that the old population is very heterogeneous. But this heterogeneity is also and especially due to the very high frequency and diversity of chronic diseases in this population.

The aim of our study was to evaluate the different patterns of psychiatric consultations in the elderly.

This is a retrospective study conducted in the outpatient hospital razi, involving 90 patients aged consultant during 2011.

In total, 90 cases were recorded. The average age of patients was 77.5 years.

The sex ratio (M / F) was 1.04. The majority of consultants had an iron status of married (51.1%) and widowed (41.1%). 77.8% of patients were illiterate. 63% of patients were retired and 49% of cases were low socioeconomic level. Personal psychiatric histories were found in 12% of consultants. The two reasons for consultation were the most common symptoms of depression (sleep problems, headaches, food refusal, sad mood, psychomotor retardation, somatic complaints) and behavioral disorders with 50 and 42.2% of cases.

The prevalence of psychiatric disorders is important in the elderly because half of those over age 65 suffer from a psychiatric disorder.
