Brief Summary:
This study will evaluate the effectiveness of memantine in improving rehabilitation outcomes and preventing major depressive disorder in older adults who have been admitted to a rehabilitation hospital for a hip fracture or cardiopulmonary condition.

Condition or disease Intervention/treatment Phase
Depression Drug: Memantine Other: Placebo Phase 4

Detailed Description:

Depression is a serious medical illness that is often difficult to diagnose and treat. It occurs in people of all ages, but is often overlooked in older adults. Depression frequently co-occurs with other serious illnesses, and may be mistaken by both patients and health care givers as a normal consequence of the illness. However, these misconceptions toward depression contribute to the underdiagnosis and undertreatment of depressive disorders in older people. In turn, depression may hinder a patient's recovery from an illness. This study will evaluate the effectiveness of memantine in improving rehabilitation outcomes and preventing major depressive disorder in older adults who have been admitted to a rehabilitation hospital for a hip fracture or a cardiopulmonary condition.

This double-blind study will last for 12 months. Participants will be randomly assigned to receive either placebo or memantine, which is a drug that is often used to treat Alzheimer's disease. Both memantine and placebo will be administered to participants for 12 weeks. All participants will be followed for an additional 40 weeks. Outcome measurements will include participants' depressive symptoms, motivation, and learned helplessness. In addition, medication side effects, functional outcome, and incidence of major depressive disorder will be measured. All measurements will be taken at Week 12 and Month 12.
