"With further refinement, the findings may improve physicians' ability to predict who will fail to respond to antidepressants. Such patients may need close follow-up and different treatments such as psychotherapy or novel medications. Second, our findings can be used in the development of new treatments for those who do not respond to classical antidepressants," Alexopoulos said in a prepared statement.
He and his team are currently studying how parts of the frontal lobes are activated when depressed patients do cognitive tasks that activate this area.

Preliminary findings show that depressed older patients cannot activate these frontal lobe parts as efficiently as non-depressed older adults," Alexopoulos said.
In other research, a team at the University of Iowa found that vascular depression can be treated with an experimental technique called repetitive transcranial magnetic stimulation (rTMS). They found that rTMS led to better remission rates than standard medication treatment, and that increasing the number of magnetic pulses significantly improved remission rates.
"These findings suggest that this new method of treatment may be particularly useful for these late life onset depressions and that even greater response rates might be achieved by utilizing more pulses of magnetic stimulation," Dr. Robert Robinson, a professor of psychiatry, said in a prepared statement.
In other reports presented at the conference, scientists urged caution in the use of antipsychotic drugs in elderly people and other patients in order to minimize metabolic, heart and stroke risks.
