Predictors of the Outcome of Late Life Depression
Study Details
Study Description
Brief Summary
Predictors of response to pharmacological treatment of major depressive disorder will be investigated. One hundred and twenty patients will be included in a naturalistic clinical trial. Psychopathology, personality traits, cognitive performance, brain structural changes and genetic polymorphisms will be evaluated. Patients will be followed for 18 months with a pharmacological treatment algorithm and will be evaluated monthly until 6th month and every 3 months, up to 18 months. Psychoeducation will be offered to patients who did not remit until 3 months of pharmacological tretment.

Detailed Description
The relevance of depression prevention and treatment in older people tend to raise in future years, considering the rapid increase of the elderly population in Brazil and the growing impact of depression (the third cause of global burden of diseases in the world according to the World Health Association 2004 report). The association between structural brain changes and treatment response in patients with late-life depression (LLD) remains an intriguing area of research. Predictors of response to pharmacological treatment of major depressive disorder will be investigated in 120 elderly patients, who will be included in a naturalistic clinical trial, that will evaluate psychopathology, personality traits, cognitive performance, brain structural changes and genetic polymorphisms. Patients will be followed for 18 months with a treatment algorithm for depression and will be evaluated monthly until 6th month and every 3 months, up to 18 months, to assess factors associated to response to treatment.
Patients who are in the antidepressant treatment group and does not reach remission (MADRS score <or =8) until 3 months of pharmacological treatment will be invited to be part of a psychoeducation program. If the patient accepts the psychoeducation intervention, he will be randomized to psychoeducation (pharmacological treatment plus psychoeducation) or treatment as usual (only pharmacological treatment). The psychoeducation program consists of 10 individual weekly sessions, conducted by a trained psychologist who will explain the main concepts of depression and its symptoms, the importance of adhering to treatment, the main side effects of pharmacological treatment, and how to cope with daily difficulties.

Outcome Measures
Primary Outcome Measures
- Change from Baseline Montgomery-Asberg Depression Scale (MADRS) below 8 during the initial 12 weeks of the study and remained below 8 until 18 months [18 months]
The investigators will consider patients remitted when their MADRS scale score decreased below 8 during the initial 12 weeks of the study and remained below 8 until 24 weeks. All patients whose MADRS scores decreased to 8 but rose above 8 during the study or whose MADRS score remained at 8 or above throughout the study were considered not remitted
Secondary Outcome Measures
- Change from baseline Clinical Global Impression (CGI) up to 18 months [18 months]
It will be applied on 1st, 2nd, 3rd, 4th, 5th, 6th, 9th, 12th, 15th, and 18th months of follow-up. On the 6th, 12th, and 18th months, the Mini Mental State Examination (MMSE), the Cognitive and self-contained part of the Cambridge Examination for Mental Disorders of the Elderly (CAMCOG)and the Bayer Activities of Daily Living Scale (B-ADL) will be applied.
- Change from baseline Hamilton-D Scale (HAM-D) up to 18 months [18 months]
It will be applied on 1st, 2nd, 3rd, 4th, 5th, 6th, 9th, 12th, 15th, and 18th months of follow-up. On the 6th, 12th, and 18th months, MMSE, the CAMCOG and the B-ADL will be applied.
- Change from baseline Mini Mental State Examination (MMSE) up to 18 months [18 months]
It will be applied on 1st, 12th, and 18th months of follow-up. On the 6th, 12th, and 18th months, MMSE, the CAMCOG and the B-ADL will be applied.
- Change from baseline Cognitive and self-contained part of the Cambridge Examination for Mental Disorders of the Elderly (CAMCOG) up to 18 months [18 months]
It will be applied on 1st, 12th, and 18th months of follow-up.
