Keeping these things in mind, the theme issue of Asian Journal
of Psychiatry on Geriatric Psychiatry is a step in the right direction.
The population based study from Karachi which assessed the
relationship of functional status and physical activity with
depression among elderly is a brave effort to understand the role
of physical activity in countering depression. This study shows that
spending more time per week in physical activity reduces the
chances of developing depression (Bhamani et al., 2015). There is a
need for similar large sample, multicentric studies from other parts
of the Asia to understand other important preventive aspects
related to geriatric mental health. The Magnetic Resonance
Imaging study on patients with late onset depression elucidates
the role of hippocampal atrophy, especially posterior hippocampus
in elderly depression (Sivakumar et al., 2015).
