Team Work in Geriatrics
Elderly individuals are the ones who are intensively exposed to the complex effects of various interactive factors on healthiness and functional capacity.

For this reason, geriatrics emerges as an approach which necessitates collaboration of various branches.
In this regard, in accordance with needs of an elderly patient, some or all experts, specialized in their fields, may have to take place in the geriatric assessment team.
Team head is Geriatrist , who has specialized in prevention and treatment of multiple and complex problems of elderly individuals. As for other team members, they are specialists such as a Nurse, a Social Worker, a Physiotherapist, a Workshop Therapist, a Dietician, a Psychotherapist and a Pharmacologist. Meanwhile, it should be kept in mind that in case an elderly individual does not have a capacity to make a decision about himself or herself, then, his or her relatives are irreplaceable members of the team, too. 
Each team member, in accordance with his or her expertise, evaluates elderly individual generally. Later, team members get together to discuss the individual with all aspects of his or her problems and determine a treatment and a follow-up plan, commonly decided by all branches, which will enable the individual to maintain the ability to perform his or her daily activities independently at the highest level. Here, although geriatrist heads the team work, it is important to emphasize the fact that all team members are experts of their fields and have important roles in evaluation and treatment of elderly individuals.
