Depression leads to appetite and weight changes that results in malnutrition, and poor nutrition predispose old individuals to psychiatric upset (depression, agitation, and irritability). Loss of appetite and weight and major criteria for diagnosis of depression. It is suggested that the neurotransmitters and hormonal changes occurring in depressing are responsible for alteration in appetite. On the other hand, dietary supplements are essential for mood regulation.

There is a vicious circle between depression and malnutrition. Therefore, clinicians should pay attention to both psychological and physical aspects during treating elderly with depression, malnutrition, or both.
